• Getting \r\n newlines to display properly in Mantis database

  - by matt_tm

  I've exported a Mantis project from one server to another and despite the MySQL SQL file (from which it was populated) showing: (15375,'\r\n1. Log out\r\n\r\n2. When logging in, start ... The final end-user view loses the \r\n and shows it only on one line: 1. Log out 2. When logging in, start typing When viewing through phpMyAdmin, I can see the record properly: 1. Log out 2. When logging in, start typing How can I correct this behavior when displaying this data?

• ForceAutoLogon Ignored in windows 7 when setting up Autologin - Autologon

  - by user1082202

  I am attempting to setup automatic logon for a windows 7 kiosk computer via the registry. I have set the values under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon like this: AutoAdminLogon = 1 ForceAutoLogon = 1 DisableCAD = 1 I have filled out the username and password fields. I have also deleted all EULA related values (a prerequisite of ForceAutoLogon) I have done this procedure on 2 computers. On computer A: When rebooting, we logon automatically. When logging out from the start menu, we logon automatically immediately after logging out. On computer B: When rebooting, we logon automatically. When logging out from the start menu, we are presented with a logon menu where the user needs to click a user name & then enter a password. It seems like the value of ForceAutoLogon requires some other prerequisite that is met on computer A, but not on computer B. What do I need to make computer B act like computer A when clicking the log off button from the windows start menu?

• Nginx, logrotate and empty files

  - by tzulberti

  I have a problem with nginx/logrotate. The problems is that nginx is logging access to 2 files (main and data). I have the following contrab setting: 0 * * * * /usr/sbin/logrotate -f /home/orwell/orwell-setup/bin/logrotate-nginx And the file "logrotate-nginx" has the following content: /tmp/data.log { rotate 90 daily missingok notifempty size 1 sharedscripts postrotate [ ! -f /tmp/nginx.pid ] || kill -USR1 `cat /tmp/nginx.pid` MORE THINGS endscript } /tmp/main.log { rotate 90 daily missingok notifempty size 1 sharedscripts postrotate [ ! -f /tmp/nginx.pid ] || kill -USR1 `cat /tmp/nginx.pid` MORE THINGS endscript } The work is done in the two files, but there is a problem that nginx stops logging into those files. Both files are created, but they are empty. Any ideas why nginx stop logging info to both files?

• Log4j: Events appear in the wrong logfile

  - by Markus

  Hi there! To be able to log and trace some events I've added a LoggingHandler class to my java project. Inside this class I'm using two different log4j logger instances - one for logging an event and one for tracing an event into different files. The initialization block of the class looks like this: public void initialize() { System.out.print("starting logging server ..."); // create logger instances logLogger = Logger.getLogger("log"); traceLogger = Logger.getLogger("trace"); // create pattern layout String conversionPattern = "%c{2} %d{ABSOLUTE} %r %p %m%n"; try { patternLayout = new PatternLayout(); patternLayout.setConversionPattern(conversionPattern); } catch (Exception e) { System.out.println("error: could not create logger layout pattern"); System.out.println(e); System.exit(1); } // add pattern to file appender try { logFileAppender = new FileAppender(patternLayout, logFilename, false); traceFileAppender = new FileAppender(patternLayout, traceFilename, false); } catch (IOException e) { System.out.println("error: could not add logger layout pattern to corresponding appender"); System.out.println(e); System.exit(1); } // add appenders to loggers logLogger.addAppender(logFileAppender); traceLogger.addAppender(traceFileAppender); // set logger level logLogger.setLevel(Level.INFO); traceLogger.setLevel(Level.INFO); // start logging server loggingServer = new LoggingServer(logLogger, traceLogger, serverPort, this); loggingServer.start(); System.out.println(" done"); } To make sure that only only thread is using the functionality of a logger instance at the same time each logging / tracing method calls the logging method .info() inside a synchronized-block. One example looks like this: public void logMessage(String message) { synchronized (logLogger) { if (logLogger.isInfoEnabled() && logFileAppender != null) { logLogger.info(instanceName + ": " + message); } } } If I look at the log files, I see that sometimes a event appears in the wrong file. One example: trace 10:41:30,773 11080 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1267093 to vehicle 1055293 (slaveControl 1) trace 10:41:30,784 11091 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1156513 to vehicle 1105792 (slaveControl 1) trace 10:41:30,796 11103 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1104306 to vehicle 1055293 (slaveControl 1) trace 10:41:30,808 11115 INFO masterControl(192.168.2.21): vehicle 1327879 was pushed to slave control 1 10:41:30,808 11115 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1101572 to vehicle 106741 (slaveControl 1) trace 10:41:30,820 11127 INFO masterControl(192.168.2.21): string broadcast message was pushed from 1055293 to vehicle 1104306 (slaveControl 1) I think that the problem occures everytime two event happen at the same time (here: 10:41:30,808). Does anybody has an idea how to solve my problem? I already tried to add a sleep() after the method call, but that doesn't helped ... BR, Markus Edit: logtrace 11:16:07,75511:16:07,755 1129711297 INFOINFO masterControl(192.168.2.21): string broadcast message was pushed from 1291400 to vehicle 1138272 (slaveControl 1)masterControl(192.168.2.21): vehicle 1333770 was added to slave control 1 or log 11:16:08,562 12104 INFO 11:16:08,562 masterControl(192.168.2.21): string broadcast message was pushed from 117772 to vehicle 1217744 (slaveControl 1) 12104 INFO masterControl(192.168.2.21): vehicle 1169775 was pushed to slave control 1 Edit 2: It seems like the problem only occurs if logging methods are called from inside a RMI thread (my client / server exchange information using RMI connections). ... Edit 3: I solved the problem by myself: It seems like log4j is NOT completely thread-save. After synchronizing all log / trace methods using a separate object everything is working fine. Maybe the lib is writing the messages to a thread-unsafe buffer before writing them to file?

• How do you stay productive when dealing with extremely badly written code?

  - by gaearon

  I don't have much experience in working in software industry, being self-taught and having participated in open source before deciding to take a job. Now that I work for money, I also have to deal with some unpleasant stuff, which is normal of course. Recently I was assigned to add logging to a large SharePoint project which is written by some programmer who obviously was learning to code on the job. After 2 years of collaboration, the client switched to our company, but the damage was done, and now somehow I need to maintain this code. Not that the code was too hard to read. Despite problems - each project has one class with several copy-pasted methods, enormous if nestings, Systems Hungarian, undisposed connections — it's still readable. However, I found myself absolutely unproductive despite working on something as simple as adding logging. Basically, I just need to go through the code step by step and add some trace calls. However, the idiocy of the code is so annoying that I get tired within 10 minutes of starting. In the beginning, I used to add using constructs, reduce nesting by reversing if's, rename the variables to readable names—but the project is large, and eventually I gave up. I know this is not the task I should be doing, but at least reducing the mess gave me some kind of psychological reward so I could keep going. Now the trick stopped working, and I still have 60% of my work to do. I started having headaches after work, and I no longer get the feeling of satisfaction I used to get - which would usually allow me to code for 10 hours straight and still feel fresh. This is not just one big rant, for I really do have an actual question: Is there a way to stay productive and not to fight the windmills? Is there some kind of psychological trick to stay focused on the task, instead of thinking “How stupid is that?” each time I see another clever trick by the previous programmer? The problem with adding logging is that I actually have to understand what the code does, and doing so hurts my brain in an unpleasant fashion.

• How to fix the “Live INT automatically logs out”

  - by ybbest

  Problem: Live INT environment automatically logs out I am trying to setup the Authentication with Windows Live ID and followed this blog post ; I have a problem logging in to live INT web site. Whenever I try to log in (https://login.live-int.com/login.srf  this is the internal Live environment to be used in a dev. environment.), after entering valid email/password I get redirected to the logout page. I tried 2 different accounts (one with existing email address, and other one with newly created @hotmail-int.com address) and 3 different browsers so I’m sure that neither account nor the browser are the cause of this. I also tried to enter wrong password, and in that case I get the message that the password is wrong. Solution: All you need is the unique ID in order to add the user to SharePoint , you can get the ID without logging into the Live INT environment. I think the Live internal environment is not working correctly for some reasons , the reason I need to login to the Live internal environment is that I need to get the unique ID for the test account so that I can add the user to SharePoint. All the blogs I have come across require you to login in order to get the unique ID. However, I figured out another way of getting the unique ID without logging in. Steps are below: Register a new test account in the Live internal environment. Go to the SharePoint site collection that has  Live ID authentication enabled and select the LiveID INT(it will be different as you could name it differently when you set up the authentication provider) from the dropdown. Try login using the Internal Live account, you will get an Access Denied Error as below showing your  unique ID for the test account. Add that account to your SharePoint Group, boom, it works. I hope it will help anyone who needs to do this stuff in the future.

• LINQ to Twitter Maintenance Feedback

  - by Joe Mayo

  Originally posted on: http://geekswithblogs.net/WinAZ/archive/2013/06/16/linq-to-twitter-maintenance-feedback.aspxIt’s always fun to receive positive feedback on your work. If you receive a sufficient amount of positive feedback, you know you’re doing something right. Sometimes, people provide negative feedback too. There are a couple ways to handle it: come back fighting or engage for clarification. The way you handle the negative feedback depends on what your goals are. Feedback Approaches If you know the feedback is incorrect and you need to promote your idea or product, you might want to come back fighting. The feedback might just be comments by a troll or competitor wanting to spread FUD. However, this could be the totally wrong approach if you misjudge the source and intentions of the feedback. In a lot of cases, feedback is a golden opportunity. Sometimes, a problem exists that you either don’t know about or don’t realize the true impact of the problem. If you decide to come back fighting, you might loose the opportunity to learn something new. However, if you engage the person providing the feedback, looking for clarification, you might learn something very important. Negative feedback and it’s clarification can lead to the collection of useful and actionable data. In my case, something that prompted this blog post, I noticed someone who tweeted a negative comment about LINQ to Twitter. Normally, any less than stellar comments are usually from folks that need help – so I help if I can. This was different. I was like “Don’t use LINQ to Twitter”. This is an open source project, the comment didn’t come from a competing project, and  sounded more like an expression of frustration. So I engaged. Not only did the person respond, but I got some decent quality feedback. What’s also interesting is a couple other side conversations sprouted on the subject, which gave me more useful data. LINQ to Twitter Thread Actions Essentially, this particular issue centered around maintenance. There are actually several sub-issues at play here: dependencies, error handling, debugging, and visibility. I’ll describe each one and my interpretation. Dependencies Dependencies are where a library has references to other libraries. This means that when you build your application, you need DLLs for the entire dependency graph for your application. There are several potential problems with this that include more libraries for configuration management, potential versioning mismatches, and lack of cross-platform support. In the early days of LINQ to Twitter, I allowed developers to contribute and add dependencies, but it became very problematic (for reasons stated). It was like a ball and chain that kept me from moving forward. So, I refactored and pulled other open-source into my project to eliminate external dependencies. This lets me fix the code in my project without relying on someone else to upgrade or fix their DLL. The motivation for this was from early negative feedback that translated as important data and acted on it. Today, LINQ to Twitter has zero dependencies. Note: Rejecting good code from community members who worked hard to make your project better is a painful experience in itself. I have to point out that any contribution was not in vain because they had a positive influence on my subsequent refactoring that resulted in a better developer experience. Error Handling Error handling has been a problem in the past. I have this combination of supporting both synchronous and asynchronous (APM) processing that can be complex at times. Within the last 6 months, I did a fair amount of refactoring to detect errors and process them properly. I also refactored TwitterQueryException so it includes important data from Twitter. During this refactoring, I’ve made breaking changes that I felt would improve the development experience (small things like renaming a callback property to Exception, rather than Error). I think the async error handling is much better than it was a year ago. For all the work I’ve done, there is more to do. I think that a combination of more error handling support, e.g. improving semantics, and education through documentation and samples will improve the error handling story. Because of what I’ve done so far, it isn’t bad, but I see opportunities for improvement. Debugging Debugging can be painful. Here’s why: you have multiple layers of technology to navigate and figure out where the real problem is – Twitter API, Security, HTTP, LINQ to Twitter, and application. You can probably add your own nuances to that list, but the point is that debugging in this environment can be complex. I think that my plans for error handling will contribute to making the debugging process easier. However, there’s more I can do in the way of documentation and guidance. Some of the questions to be answered revolve around when something goes wrong, how does the developer figure out that there is a problem, what the problem is, and what to do about it. One example that has gone a long way to helping LINQ to Twitter developers is the 401 FAQ. A 401 Unauthorized is the error that the Twitter API returns when a use isn’t able to authenticate and is one of the most difficult problems faced by LINQ to Twitter developers. What I did was read guidance from Twitter and collect techniques from my own development and actions helping other developers to compile an extensive list of reasons for the 401 and ways to fix the problem. At one time, over half of the questions I answered in the forums were to help solve 401 issues. After publishing the 401 FAQ, I rarely get a 401 question and it’s because the person didn’t know about the FAQ. If the person is too lazy to read the FAQ, that’s not my issue, but the results in support issues have been dramatic. I think debugging can benefit from the education and documentation approach, but I’m always open to suggestions on whatever else I can do. Visibility Visibility is a nuance of the error handling/debugging discussion but is deeply rooted in comfort and control. The questions to ask in this area are what is happening as my code runs and how testable is the code. In support of these areas, LINQ to Twitter does have logging and TwitterContext properties that help see what’s happening on requests. The logging functionality allows any developer to connect a TextWriter to the Log property of TwitterContext to see what’s happening. Further, TwitterContext has a Headers property to see the headers Twitter returns and a RawResults property to show the Json string Twitter returns. From a testing perspective, I’ve been able to write hundreds of unit tests, over 600 when this post is published, and growing. If you write your own library, you have full control over all of these aspects. The tradeoff here is that while you have access to the LINQ to Twitter source code and modify it for all the visibility, LINQ to Twitter *will* change (which is good) and you will have to figure out how to merge that with your changes (which is hard). The fact is that this is a limitation of any 3rd party library, not just LINQ to Twitter. So, it’s a design decision where the tradeoff is between control and productivity. That said, there are things I can do with LINQ to Twitter to make the visibility story more compelling. I think there are opportunities to improve diagnostics. This would be a ton of work because it would need to provide multi-level logging that can be tuned for production and support any logging provider you want to attach. I’ve considered approaches such as how the new Semantic Logging application block connects to Windows Error Reporting as a potential target. Whatever I do would need to be extensible without creating native external dependencies. e.g. how many 3rd party libraries force a dependency on a logging framework that you don’t use. So, this won’t be an easy feat, but I believe it can be part of the roadmap. I think that a lot of developers are unaware of existing visibility features, so the first step would be to provide more documentation and guidance. My thought are that this would lead to more feedback that will help improve this area. Summary Recent feedback highlights some of items that are important to LINQ to Twitter developers, such as dependencies, error handling, debugging, and visibility. I know that there are maintenance issues that have been problems for LINQ to Twitter developers in the past. I’ve done a lot of work in this area, such as improving error handling, adding visibility features, and providing extensive API documentation. That said, there is more to be done to make LINQ to Twitter the best Twitter API experience available for .NET developers and I welcome anyone’s thoughts on what I’ve written here or new improvements. @JoeMayo

• Change the Log Level of Node Manager.

  - by adejuanc

  This is useful to troubleshoot issues related to Node Manager, such as problems starting a Managed Server or reasons a server could be (re)started. To change the Log Level of Node Manager, you need to edit the nodemanager.properties file. This is usually located at: <MIDDLEWARE_HOME>/wlserver_10.3/common/nodemanager What you need to modify is property: ...LogLevel=INFO... Information about the appropriate values for this property is available in the Node Manager Documentation at 10.3 WebLogic Documentation (and in further releases) which states: LogLevel: Severity level of logging used for the Node Manager log. Node Manager uses the same logging levels as WebLogic Server. Default value: INFO However, this is incorrect. WLS has its own implementation of LogLevel, but Node Manager uses the standard Log Level from the java.util.logging.Level class. Therefore, the possible values for Node Manager LogLevel, in descending order are: SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value) The highest value provides only messages at the severe level. The warning level provides warning messages and severe messages, and so on. Besides those levels, ALL and OFF are also accepted. For example, if you only want Severe messages to be logged, select SEVERE. If you need the most detailed tracing available, select FINEST. For more information on what it will log at each level, please read the Java SE API for LoggingLevel.

• What's the best way to handle numerous recurring log entries in game loop?

  - by Kaa

  I have a custom logging system, use of which is scattered all over the engine and game. The system is linked to a "LogStore" that has an std::vector<string> logs[NUM_LOG_TYPES] - each vector corresponds with it's log type (info, error, debug, etc.). There's one extra std::vector that has "coordinates" to all log entries in the order they were received. Now, all the logging output is also displayed inside my development console in the game. The game console is handled by HTML-type GUI and therefore requires a new <p> element being added for each log output. My problem is that the log entries that are generated in the main loop each frame freeze the engine, because they continue to add elements to the in-game console, and if the console or guy generates a warning - that creates an infinite logging loop. I want to solve it by handling the recurring log entries in an elegant way that lets you know that something is critically wrong, but won't freeze the engine - like displaying the count of errors in the last 60 frames instead of displaying errors themselves. But how do you guys handle this? Does anyone know any nifty tricks to do this? I understand the question may sound vague, but if someone came across this type of issue I'm sure they would know exactly what's happening. Example problematic log entries: OpenGL warnings (I actually do check for errors every frame in many places) Really any prints anywhere in the main loop (may be debugging, may be warnings)

• java.util.ConcurrentModificationException when serializing non thread-safe maps

  - by [email protected]

  We have got some questions related to exceptions thrown during a map serialization like the following one (in this example, for a LRUMap): java.util.ConcurrentModificationExceptionat org.apache.commons.collections.SequencedHashMap$OrderedIterator.next(Unknown Source)at org.apache.commons.collections.LRUMap.writeExternal(Unknown Source)at java.io.ObjectOutputStream.writeExternalData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java(Inlined CompiledCode))at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java(Compiled Code))at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.writeSerializable(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.util.ExternalizableHelper.writeObjectInternal(ExternalizableHelper.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.serializeInternal(ExternalizableHelper.java(Compiled Code))at com.tangosol.util.ExternalizableHelper.toBinary(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.util.ExternalizableHelper.toBinary(ExternalizableHelper.java(InlinedCompiled Code))at com.tangosol.coherence.servlet.TraditionalHttpSessionModel$OptimizedHolder.serializeValue(TraditionalHttpSessionModel.java(Inlined Compiled Code))at com.tangosol.coherence.servlet.TraditionalHttpSessionModel$OptimizedHolder.getBinary(TraditionalHttpSessionModel.java(Compiled Code)) This is caused because LRUMap is not thread safe, so if another thread is modifying the content of that same map while serialization is in progress, then the ConcurrentModificationException will be thrown. Also, the map must be synchronized. Other structures like java.util.HashMap are not thread safe too. To avoid this kind of problems, it is recommended to use a thread-safe and synchronized map such as java.util.Map, java.util.Hashtable or com.tangosol.util.SafeHashMap. You may also need to use the synchronizedMap(Map) method from Class java.util.Collections.

• Tomcat can't talk to MySql after outage

  - by gav

  I missed a payment for my server and hey suspended my account for a day or so. When they brought the server back up all my data was in tact but for some reason Tomcat can't make a JDBC connection to my MySql server. They both run on the same machine and hence I have a bind address of 127.0.0.1. It's strange because I have reset the machine of my own accord before without issue but clearly something has been reset in the downtime. I followed this guide (Just the bits which don't concern S3, I am not on Amazon infrastructure) originally and everything worked as expected. I'm very new to being a SysAdmin and I'm not sure what to try, how would you go about diagnosing this issue? The stack trace I get is as follows; INFO: Deploying web application archive myapp-1.1.war 2010-05-26 22:07:22,221 [main] ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Cannot resolve reference to bean 'hibernateProperties' while setting bean property 'hibernateProperties'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateProperties': Cannot resolve reference to bean 'dialectDetector' while setting bean property 'properties' with key [hibernate.dialect]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dialectDetector': Invocation of init method failed; nested exception is org.springframework.jdbc.support.MetaDataAccessException: Could not get Connection for extracting meta data; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.

• How do I compile a Wikipedia lens and install?

  I read a tutorial about how to compile and install a Wikipedia lens, but it didn't work. The tutorial sounds easy - i just copied and pasted to the file that was suppose to edit.

• Forwarding rsyslog to syslog-ng, with FQDN and facility separation

  - by Joshua Miller

  I'm attempting to configure my rsyslog clients to forward messages to my syslog-ng log repository systems. Forwarding messages works "out of the box", but my clients are logging short names, not FQDNs. As a result the messages on the syslog repo use short names as well, which is a problem because one can't determine which system the message originated from easily. My clients get their names through DHCP / DNS. I've tried a number of solutions trying to get this working, but without success. I'm using rsyslog 4.6.2 and syslog-ng 3.2.5. I've tried setting $PreserveFQDN on as the first directive in /etc/rsyslog.conf (and restarting rsyslog of course). It seems to have no effect. hostname --fqdn on the client returns the proper FQDN, so the problem isn't whether the system can actually figure out its own FQDN. $LocalHostName <fqdn> looked promising, but this directive isn't available in my version of rsyslog (Available since 4.7.4+, 5.7.3+, 6.1.3+). Upgrading isn't an option at the moment. Configuring the syslog-ng server to populate names based on reverse lookups via DNS isn't an option. There are complexities with reverse DNS and the public cloud. Specifying for the forwarder to use a custom template seems like a viable option at first glance. I can specify the following, which causes local logging to begin using the FQDN on the syslog-ng repo. $template MyTemplate, "%timestamp% <FQDN> %syslogtag%%msg%" $ActionForwardDefaultTemplate MyTemplate However, when I put this in place syslog-ng seems to be unable to categorize messages by facility or priority. Messages come in as FQDN, but everything is put in to user.log. When I don't use the custom template, messages are properly categorized under facility and priority, but with the short name. So, in summary, if I manually trick rsyslog into including the FQDN, priority and facility becomes lost details to syslog-ng. How can I get rsyslog to do FQDN logging which works properly going to a syslog-ng repository? rsyslog client config: $ModLoad imuxsock.so # provides support for local system logging (e.g. via logger command) $ModLoad imklog.so # provides kernel logging support (previously done by rklogd) $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg * uucp,news.crit /var/log/spooler local7.* /var/log/boot.log $WorkDirectory /var/spool/rsyslog # where to place spool files $ActionQueueFileName fwdRule1 # unique name prefix for spool files $ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible) $ActionQueueSaveOnShutdown on # save messages to disk on shutdown $ActionQueueType LinkedList # run asynchronously $ActionResumeRetryCount -1 # infinite retries if host is down *.* @syslog-ng1.example.com *.* @syslog-ng2.example.com syslog-ng configuration (abridged for brevity): options { flush_lines (0); time_reopen (10); log_fifo_size (1000); long_hostnames (off); use_dns (no); use_fqdn (yes); create_dirs (no); keep_hostname (yes); }; source src { unix-stream("/dev/log"); internal(); udp(ip(0.0.0.0) port(514)); }; destination per_host_destination { file( "/var/log/syslog-ng/devices/$HOST/$FACILITY.log" owner("root") group("root") perm(0644) dir_owner(root) dir_group(root) dir_perm(0775) create_dirs(yes)); }; log { source(src); destination(per_facility_destination); };

• feedparser fails during script run, but can't reproduce in interactive python console

  - by Rhubarb

  It's failing with this when I run eclipse or when I run my script in iPython: 'ascii' codec can't decode byte 0xe2 in position 32: ordinal not in range(128) I don't know why, but when I simply execute the feedparse.parse(url) statement using the same url, there is no error thrown.

• Android - Persist file when app closes.

  - by Donal Rafferty

  I am creating a file in my Android application as follows: HEADINGSTRING = new String("Android Debugging " + "\n" "XML test Debugging"); } public void setUpLogging(Context context){ Log.d("LOGGING", "Setting up logging....."); try { // catches IOException below FileOutputStream fOut = context.openFileOutput(FILE_NAME,Context.MODE_APPEND); OutputStreamWriter osw = new OutputStreamWriter(fOut); // Write the string to the file osw.write(HEADINGSTRING); /* ensure that everything is * really written out and close */ osw.flush(); osw.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally{ Log.d("LOGGING", "Finished logging setup....."); } } And I write to the file during the running of the app as follows: public void addToLog(File file, String text) throws IOException { BufferedWriter bw = new BufferedWriter (new FileWriter(file, true)); bw.write ("\n" + text); bw.newLine(); bw.flush(); bw.close(); } This works fine but when my app closes the file gets deleted and when the app is run again all the information I wrote to it is gone. How can I make sure the file persists even after closure of the app? Update: I have changed MODE_PRIVATE to MODE_APPEND but the problem still remains.

• [JAX-B] How can I ignore a superclass?

  - by MrSpandex

  I'm trying to write a web service for the java.util.logging api. So I wrote a class MyLogRecord that inherits from LogRecord. I annotated this class with JAX-B annotations, including @XmlAccessorType(XmlAccessType.NONE) so it would ignore non-annotated fields and properties. When I start up tomcat, I get errors that java.util.logging.Level and other java.util.logging classes do not have a default constructor, but none of my annotated methods make any reference to the Level class or any of the other java.util.logging classes. These are referenced by the parent class. My sub-class has everything it needs defined. How can I get JAX-B to ignore the parent class completely? Update: I found another post on this, which suggests modifying the parent class. This is obviously not possible because I am extending a java.util class. IS there any way to do this without modifying the superclass? Update2: I found a thread on java.net for a similar problem. That thread resulted in an enhancement request, which was marked as a duplicate of another issue, which resulted in the @XmlTransient annotation. The comments on these bug reports lead me to believe this is impossible in the current spec.

• http_access.log on WebSphere 6.1.0.29

  - by DavidG

  I am running WebSphere 6.1.0.29 and I need to track the requests being made to an Enterprise Application. Previously I did this by routing the requests through a proxy server, but I need to repeat the exercise and I figure there must be a simpler way. Does anyone know how to enable HTTP access logging? I have been through the console an thought I had enabled http_access.log and http_error.log via: Application servers server1 HTTP error and NCSA access logging (where 'server1' is the application server) I've enabled the service at startup, and ticked the boxes to enable access logging and error logging - however... nothing has happened. I have restarted the server, restarted the Enterprise apps and even did a "find . -name" for the log files - but they don't seem to be anywhere on the system. I saw on a JavaRanch thread someone suggested writing a custom filter for requests in an application, but this seems like wild overkill - plus I am doing the logs to test a pre-built binary, so I don't want to mess with the code. Anyone have any ideas/suggestions? Help! :-)

• Printing the "source" class in a log statement with a log4j wrapper

  - by Dur4ndal

  My application has a homebrew logging class that I'm migrating to using log4j under the covers. However, since I'm using the homebrew class to pass the rest of the application's logging statements to log4j, the output statements are logged as coming from the wrapper class instead of the source class. Is there a way to ensure that the "correct" source is being shown besides creating new org.apache.log4j.Logger instances for every log statement? I've also tried using the Logger.log(String callerFQCN, Priority level, Object message, Throwable t) method, but it doesnt seem to be working, for example: public class Logger2 { public static org.apache.log4j.Logger log4JLogger = org.apache.log4j.Logger.getLogger(Logger2.class); public static void warning(Object source, String message) { log(source, message, Level.WARN, null) } private static void log(Object source, String message, Level level, Throwable t) { String className = source.getClass().getName(); System.out.println("Logging class should be " + className); log4JLogger.log(className, loggingLevel, message, t); } } When called by: public void testWarning() { Logger2.warning(new Integer(3), "This should warn"); } Prints: Logging class should be java.lang.Integer 2010-05-25 10:49:57,152 WARN test.Logger2 - This should warn

• Uploading multiple files using Spring MVC 3.0.2 after HiddenHttpMethodFilter has been enabled

  - by Tiny

  I'm using Spring version 3.0.2. I need to upload multiple files using the multiple="multiple" attribute of a file browser such as, <input type="file" id="myFile" name="myFile" multiple="multiple"/> (and not using multiple file browsers something like the one stated by this answer, it indeed works I tried). Although no versions of Internet Explorer supports this approach unless an appropriate jQuery plugin/widget is used, I don't care about it right now (since most other browsers support this). This works fine with commons fileupload but in addition to using RequestMethod.POST and RequestMethod.GET methods, I also want to use other request methods supported and suggested by Spring like RequestMethod.PUT and RequestMethod.DELETE in their own appropriate places. For this to be so, I have configured Spring with HiddenHttpMethodFilter which goes fine as this question indicates. but it can upload only one file at a time even though multiple files in the file browser are chosen. In the Spring controller class, a method is mapped as follows. @RequestMapping(method={RequestMethod.POST}, value={"admin_side/Temp"}) public String onSubmit(@RequestParam("myFile") List<MultipartFile> files, @ModelAttribute("tempBean") TempBean tempBean, BindingResult error, Map model, HttpServletRequest request, HttpServletResponse response) throws IOException, FileUploadException { for(MultipartFile file:files) { System.out.println(file.getOriginalFilename()); } } Even with the request parameter @RequestParam("myFile") List<MultipartFile> files which is a List of type MultipartFile (it can always have only one file at a time). I could find a strategy which is likely to work with multiple files on this blog. I have gone through it carefully. The solution below the section SOLUTION 2 – USE THE RAW REQUEST says, If however the client insists on using the same form input name such as ‘files[]‘ or ‘files’ and then populating that name with multiple files then a small hack is necessary as follows. As noted above Spring 2.5 throws an exception if it detects the same form input name of type file more than once. CommonsFileUploadSupport – the class which throws that exception is not final and the method which throws that exception is protected so using the wonders of inheritance and subclassing one can simply fix/modify the logic a little bit as follows. The change I’ve made is literally one word representing one method invocation which enables us to have multiple files incoming under the same form input name. It attempts to override the method protected MultipartParsingResult parseFileItems(List fileItems, String encoding) {} of the abstract class CommonsFileUploadSupport by extending the class CommonsMultipartResolver such as, package multipartResolver; import java.io.UnsupportedEncodingException; import java.util.HashMap; import java.util.Iterator; import java.util.List; import java.util.Map; import javax.servlet.ServletContext; import org.apache.commons.fileupload.FileItem; import org.springframework.util.StringUtils; import org.springframework.web.multipart.MultipartException; import org.springframework.web.multipart.MultipartFile; import org.springframework.web.multipart.commons.CommonsMultipartFile; import org.springframework.web.multipart.commons.CommonsMultipartResolver; final public class MultiCommonsMultipartResolver extends CommonsMultipartResolver { public MultiCommonsMultipartResolver() { } public MultiCommonsMultipartResolver(ServletContext servletContext) { super(servletContext); } @Override @SuppressWarnings("unchecked") protected MultipartParsingResult parseFileItems(List fileItems, String encoding) { Map<String, MultipartFile> multipartFiles = new HashMap<String, MultipartFile>(); Map multipartParameters = new HashMap(); // Extract multipart files and multipart parameters. for (Iterator it = fileItems.iterator(); it.hasNext();) { FileItem fileItem = (FileItem) it.next(); if (fileItem.isFormField()) { String value = null; if (encoding != null) { try { value = fileItem.getString(encoding); } catch (UnsupportedEncodingException ex) { if (logger.isWarnEnabled()) { logger.warn("Could not decode multipart item '" + fileItem.getFieldName() + "' with encoding '" + encoding + "': using platform default"); } value = fileItem.getString(); } } else { value = fileItem.getString(); } String[] curParam = (String[]) multipartParameters.get(fileItem.getFieldName()); if (curParam == null) { // simple form field multipartParameters.put(fileItem.getFieldName(), new String[] { value }); } else { // array of simple form fields String[] newParam = StringUtils.addStringToArray(curParam, value); multipartParameters.put(fileItem.getFieldName(), newParam); } } else { // multipart file field CommonsMultipartFile file = new CommonsMultipartFile(fileItem); if (multipartFiles.put(fileItem.getName(), file) != null) { throw new MultipartException("Multiple files for field name [" + file.getName() + "] found - not supported by MultipartResolver"); } if (logger.isDebugEnabled()) { logger.debug("Found multipart file [" + file.getName() + "] of size " + file.getSize() + " bytes with original filename [" + file.getOriginalFilename() + "], stored " + file.getStorageDescription()); } } } return new MultipartParsingResult(multipartFiles, multipartParameters); } } What happens is that the last line in the method parseFileItems() (the return statement) i.e. return new MultipartParsingResult(multipartFiles, multipartParameters); causes a compile-time error because the first parameter multipartFiles is a type of Map implemented by HashMap but in reality, it requires a parameter of type MultiValueMap<String, MultipartFile> It is a constructor of a static class inside the abstract class CommonsFileUploadSupport, public abstract class CommonsFileUploadSupport { protected static class MultipartParsingResult { public MultipartParsingResult(MultiValueMap<String, MultipartFile> mpFiles, Map<String, String[]> mpParams) { } } } The reason might be - this solution is about the Spring version 2.5 and I'm using the Spring version 3.0.2 which might be inappropriate for this version. I however tried to replace the Map with MultiValueMap in various ways such as the one shown in the following segment of code, MultiValueMap<String, MultipartFile>mul=new LinkedMultiValueMap<String, MultipartFile>(); for(Entry<String, MultipartFile>entry:multipartFiles.entrySet()) { mul.add(entry.getKey(), entry.getValue()); } return new MultipartParsingResult(mul, multipartParameters); but no success. I'm not sure how to replace Map with MultiValueMap and even doing so could work either. After doing this, the browser shows the Http response, HTTP Status 400 - type Status report message description The request sent by the client was syntactically incorrect (). Apache Tomcat/6.0.26 I have tried to shorten the question as possible as I could and I haven't included unnecessary code. How could be made it possible to upload multiple files after Spring has been configured with HiddenHttpMethodFilter? That blog indicates that It is a long standing, high priority bug. If there is no solution regarding the version 3.0.2 (3 or higher) then I have to disable Spring support forever and continue to use commons-fileupolad as suggested by the third solution on that blog omitting the PUT, DELETE and other request methods forever. Just curiously waiting for a solution and/or suggestion. Very little changes to the code in the parseFileItems() method inside the class MultiCommonsMultipartResolver might make it to upload multiple files but I couldn't succeed in my attempts (again with the Spring version 3.0.2 (3 or higher)).

• Overview of SOA Diagnostics in 11.1.1.6

  - by ShawnBailey

  What tools are available for diagnosing SOA Suite issues? There are a variety of tools available to help you and Support diagnose SOA Suite issues in 11g but it can be confusing as to which tool is appropriate for a particular situation and what their relationships are. This blog post will introduce the various tools and attempt to clarify what each is for and how they are related. Let's first list the tools we'll be addressing: RDA: Remote Diagnostic Agent DFW: Diagnostic Framework Selective Tracing DMS: Dynamic Monitoring Service ODL: Oracle Diagnostic Logging ADR: Automatic Diagnostics Repository ADRCI: Automatic Diagnostics Repository Command Interpreter WLDF: WebLogic Diagnostic Framework This overview is not mean to be a comprehensive guide on using all of these tools, however, extensive reference materials are included that will provide many more details on their execution. Another point to note is that all of these tools are applicable for Fusion Middleware as a whole but specific products may or may not have implemented features to leverage them. A couple of the tools have a WebLogic Scripting Tool or 'WLST' interface. WLST is a command interface for executing pre-built functions and custom scripts against a domain. A detailed WLST tutorial is beyond the scope of this post but you can find general information here. There are more specific resources in the below sections. In this post when we refer to 'Enterprise Manager' or 'EM' we are referring to Enterprise Manager Fusion Middleware Control. RDA (Remote Diagnostic Agent) RDA is a standalone tool that is used to collect both static configuration and dynamic runtime information from the SOA environment. RDA is generally run manually from the command line against a domain or single server. When opening a new Service Request, including an RDA collection can dramatically decrease the back and forth required to collect logs and configuration information for Support. After installing RDA you configure it to use the SOA Suite module as decribed in the referenced resources. The SOA module includes the Oracle WebLogic Server (WLS) module by default in order to include all of the relevant information for the environment. In addition to this basic configuration there is also an advanced mode where you can set the number of thread dumps for the collections, log files, Incidents, etc. When would you use it? When creating a Service Request or otherwise working with Oracle resources on an issue, capturing environment snapshots to baseline your configuration or to diagnose an issue on your own. How is it related to the other tools? RDA is related to DFW in that it collects the last 10 Incidents from the server by default. In a similar manner, RDA is related to ODL through its collection of the diagnostic logs and these may contain information from Selective Tracing sessions. Examples of what it currently collects: (for details please see the links in the Resources section) Diagnostic Logs (ODL) Diagnostic Framework Incidents (DFW) SOA MDS Deployment Descriptors SOA Repository Summary Statistics Thread Dumps Complete Domain Configuration RDA Resources: Webcast Recording: Using RDA with Oracle SOA Suite 11g Blog Post: Diagnose SOA Suite 11g Issues Using RDA Download RDA How to Collect Analysis Information Using RDA for Oracle SOA Suite 11g Products [ID 1350313.1] How to Collect Analysis Information Using RDA for Oracle SOA Suite and BPEL Process Manager 11g [ID 1352181.1] Getting Started With Remote Diagnostic Agent: Case Study - Oracle WebLogic Server (Video) [ID 1262157.1] top DFW (Diagnostic Framework) DFW provides the ability to collect specific information for a particular problem when that problem occurs. DFW is included with your SOA Suite installation and deployed to the domain. Let's define the components of DFW. Diagnostic Dumps: Specific diagnostic collections that are defined at either the 'system' or product level. Examples would be diagnostic logs or thread dumps. Incident: A collection of Diagnostic Dumps associated with a particular problem Log Conditions: An Oracle Diagnostic Logging event that DFW is configured to listen for. If the event is identified then an Incident will be created. WLDF Watch: The WebLogic Diagnostic Framework or 'WLDF' is not a component of DFW, however, it can be a source of DFW Incident creation through the use of a 'Watch'. WLDF Notification: A Notification is a component of WLDF and is the link between the Watch and DFW. You can configure multiple Notification types in WLDF and associate them with your Watches. 'FMWDFW-notification' is available to you out of the box to allow for DFW notification of Watch execution. Rule: Defines a WLDF Watch or Log Condition for which we want to associate a set of Diagnostic Dumps. When triggered the specified dumps will be collected and added to the Incident Rule Action: Defines the specific Diagnostic Dumps to collect for a particular rule ADR: Automatic Diagnostics Repository; Defined for every server in a domain. This is where Incidents are stored Now let's walk through a simple flow: Oracle Web Services error message OWS-04086 (SOAP Fault) is generated on managed server 1 DFW Log Condition for OWS-04086 evaluates to TRUE DFW creates a new Incident in the ADR for managed server 1 DFW executes the specified Diagnostic Dumps and adds the output to the Incident In this case we'll grab the diagnostic log and thread dump. We might also want to collect the WSDL binding information and SOA audit trail When would you use it? When you want to automatically collect Diagnostic Dumps at a particular time using a trigger or when you want to manually collect the information. In either case it can be readily uploaded to Oracle Support through the Service Request. How is it related to the other tools? DFW generates Incidents which are collections of Diagnostic Dumps. One of the system level Diagonstic Dumps collects the current server diagnostic log which is generated by ODL and can contain information from Selective Tracing sessions. Incidents are included in RDA collections by default and ADRCI is a tool that is used to package an Incident for upload to Oracle Support. In addition, both ODL and DMS can be used to trigger Incident creation through DFW. The conditions and rules for generating Incidents can become quite complicated and the below resources go into more detail. A simpler approach to leveraging at least the Diagnostic Dumps is through WLST (WebLogic Scripting Tool) where there are commands to do the following: Create an Incident Execute a single Diagnostic Dump Describe a Diagnostic Dump List the available Diagnostic Dumps The WLST option offers greater control in what is generated and when. It can be a great help when collecting information for Support. There are overlaps with RDA, however, DFW is geared towards collecting specific runtime information when an issue occurs while existing Incidents are collected by RDA. There are 3 WLDF Watches configured by default in a SOA Suite 11g domain: Stuck Threads, Unchecked Exception and Deadlock. These Watches are enabled by default and will generate Incidents in ADR. They are configured to reset automatically after 30 seconds so they have the potential to create multiple Incidents if these conditions are consistent. The Incidents generated by these Watches will only contain System level Diagnostic Dumps. These same System level Diagnostic Dumps will be included in any application scoped Incident as well. Starting in 11.1.1.6, SOA Suite is including its own set of application scoped Diagnostic Dumps that can be executed from WLST or through a WLDF Watch or Log Condition. These Diagnostic Dumps can be added to an Incident such as in the earlier example using the error code OWS-04086. soa.config: MDS configuration files and deployed-composites.xml soa.composite: All artifacts related to the deployed composite soa.wsdl: Summary of endpoints configured for the composite soa.edn: EDN configuration summary if applicable soa.db: Summary DB information for the SOA repository soa.env: Coherence cluster configuration summary soa.composite.trail: Partial audit trail information for the running composite The current release of RDA has the option to collect the soa.wsdl and soa.composite Diagnostic Dumps. More Diagnostic Dumps for SOA Suite products are planned for future releases along with enhancements to DFW itself. DFW Resources: Webcast Recording: SOA Diagnostics Sessions: Diagnostic Framework Diagnostic Framework Documentation DFW WLST Command Reference Documentation for SOA Diagnostic Dumps in 11.1.1.6 top Selective Tracing Selective Tracing is a facility available starting in version 11.1.1.4 that allows you to increase the logging level for specific loggers and for a specific context. What this means is that you have greater capability to collect needed diagnostic log information in a production environment with reduced overhead. For example, a Selective Tracing session can be executed that only increases the log level for one composite, only one logger, limited to one server in the cluster and for a preset period of time. In an environment where dozens of composites are deployed this can dramatically reduce the volume and overhead of the logging without sacrificing relevance. Selective Tracing can be administered either from Enterprise Manager or through WLST. WLST provides a bit more flexibility in terms of exactly where the tracing is run. When would you use it? When there is an issue in production or another environment that lends itself to filtering by an available context criteria and increasing the log level globally results in too much overhead or irrelevant information. The information is written to the server diagnostic log and is exportable from Enterprise Manager How is it related to the other tools? Selective Tracing output is written to the server diagnostic log. This log can be collected by a system level Diagnostic Dump using DFW or through a default RDA collection. Selective Tracing also heavily leverages ODL fields to determine what to trace and to tag information that is part of a particular tracing session. Available Context Criteria: Application Name Client Address Client Host Composite Name User Name Web Service Name Web Service Port Selective Tracing Resources: Webcast Recording: SOA Diagnostics Session: Using Selective Tracing to Diagnose SOA Suite Issues How to Use Selective Tracing for SOA [ID 1367174.1] Selective Tracing WLST Reference top DMS (Dynamic Monitoring Service) DMS exposes runtime information for monitoring. This information can be monitored in two ways: Through the DMS servlet As exposed MBeans The servlet is deployed by default and can be accessed through http://<host>:<port>/dms/Spy (use administrative credentials to access). The landing page of the servlet shows identical columns of what are known as Noun Types. If you select a Noun Type you will see a table in the right frame that shows the attributes (Sensors) for the Noun Type and the available instances. SOA Suite has several exposed Noun Types that are available for viewing through the Spy servlet. Screenshots of the Spy servlet are available in the Knowledge Base article How to Monitor Runtime SOA Performance With the Dynamic Monitoring Service (DMS). Every Noun instance in the runtime is exposed as an MBean instance. As such they are generally available through an MBean browser and available for monitoring through WLDF. You can configure a WLDF Watch to monitor a particular attribute and fire a notification when the threshold is exceeded. A WLDF Watch can use the out of the box DFW notification type to notify DFW to create an Incident. When would you use it? When you want to monitor a metric or set of metrics either manually or through an automated system. When you want to trigger a WLDF Watch based on a metric exposed through DMS. How is it related to the other tools? DMS metrics can be monitored with WLDF Watches which can in turn notify DFW to create an Incident. DMS Resources: How to Monitor Runtime SOA Performance With the Dynamic Monitoring Service (DMS) [ID 1368291.1] How to Reset a SOA 11g DMS Metric DMS Documentation top ODL (Oracle Diagnostic Logging) ODL is the primary facility for most Fusion Middleware applications to log what they are doing. Whenever you change a logging level through Enterprise Manager it is ultimately exposed through ODL and written to the server diagnostic log. A notable exception to this is WebLogic Server which uses its own log format / file. ODL logs entries in a consistent, structured way using predefined fields and name/value pairs. Here's an example of a SOA Suite entry: [2012-04-25T12:49:28.083-06:00] [AdminServer] [ERROR] [] [oracle.soa.bpel.engine] [tid: [ACTIVE].ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: ] [ecid: 0963fdde7e77631c:-31a6431d:136eaa46cda:-8000-00000000000000b4,0] [errid: 41] [WEBSERVICE_PORT.name: BPELProcess2_pt] [APP: soa-infra] [composite_name: TestProject2] [J2EE_MODULE.name: fabric] [WEBSERVICE.name: bpelprocess1_client_ep] [J2EE_APP.name: soa-infra] Error occured while handling a post operation[[ When would you use it? You'll use ODL almost every time you want to identify and diagnose a problem in the environment. The entries are written to the server diagnostic log. How is it related to the other tools? The server diagnostic logs are collected by DFW and RDA. Selective Tracing writes its information to the diagnostic log as well. Additionally, DFW log conditions are triggered by ODL log events. ODL Resources: ODL Documentation top ADR (Automatic Diagnostics Repository) ADR is not a tool in and of itself but is where DFW stores the Incidents it creates. Every server in the domain has an ADR location which can be found under <SERVER_HOME>/adr. This is referred to the as the ADR 'Base' location. ADR also has what are known as 'Home' locations. Example: You have a domain called 'myDomain' and an associated managed server called 'myServer'. Your admin server is called 'AdminServer'. Your domain home directory is called 'myDomain' and it contains a 'servers' directory. The 'servers' directory contains a directory for the managed server called 'myServer' and here is where you'll find the 'adr' directory which is the ADR 'Base' location for myServer. To get to the ADR 'Home' locations we drill through a few levels: diag/ofm/myDomain/ In an 11.1.1.6 SOA Suite domain you will see 2 directories here, 'myServer' and 'soa-infra'. These are the ADR 'Home' locations. 'myServer' is the 'system' ADR home and contains system level Incidents. 'soa-infra' is the name that SOA Suite used to register with DFW and this ADR home contains SOA Suite related Incidents Each ADR home location contains a series of directories, one of which is called 'incident'. This is where your Incidents are stored. When would you use it? It's a good idea to check on these locations from time to time to see whether a lot of Incidents are being generated. They can be cleaned out by deleting the Incident directories or through the ADRCI tool. If you know that an Incident is of particular interest for an issue you're working with Oracle you can simply zip it up and provide it. How does it relate to the other tools? ADR is obviously very important for DFW since it's where the Incidents are stored. Incidents contain Diagnostic Dumps that may relate to diagnostic logs (ODL) and DMS metrics. The most recent 10 Incident directories are collected by RDA by default and ADRCI relies on the ADR locations to help manage the contents. top ADRCI (Automatic Diagnostics Repository Command Interpreter) ADRCI is a command line tool for packaging and managing Incidents. When would you use it? When purging Incidents from an ADR Home location or when you want to package an Incident along with an offline RDA collection for upload to Oracle Support. How does it relate to the other tools? ADRCI contains a tool called the Incident Packaging System or IPS. This is used to package an Incident for upload to Oracle Support through a Service Request. Starting in 11.1.1.6 IPS will attempt to collect an offline RDA collection and include it with the Incident package. This will only work if Perl is available on the path, otherwise it will give a warning and package only the Incident files. ADRCI Resources: How to Use the Incident Packaging System (IPS) in SOA 11g [ID 1381259.1] ADRCI Documentation top WLDF (WebLogic Diagnostic Framework) WLDF is functionality available in WebLogic Server since version 9. Starting with FMw 11g a link has been added between WLDF and the pre-existing DFW, the WLDF Watch Notification. Let's take a closer look at the flow: There is a need to monitor the performance of your SOA Suite message processing A WLDF Watch is created in the WLS console that will trigger if the average message processing time exceeds 2 seconds. This metric is monitored through a DMS MBean instance. The out of the box DFW Notification (the Notification is called FMWDFW-notification) is added to the Watch. Under the covers this notification is of type JMX. The Watch is triggered when the threshold is exceeded and fires the Notification. DFW has a listener that picks up the Notification and evaluates it according to its rules, etc When it comes to automatic Incident creation, WLDF is a key component with capabilities that will grow over time. When would you use it? When you want to monitor the WLS server log or an MBean metric for some condition and fire a notification when the Watch is triggered. How does it relate to the other tools? WLDF is used to automatically trigger Incident creation through DFW using the DFW Notification.

• Does IntelliJ-Idea support Groovy 2.x?

  I just tried IntelliJ-Idea 11.x and 12.x (EPA), but when I use Groovy 2.0.1 or 2.0.5, the code can't be run and there are some errors out there.

• Launch script on login to RDS - server side

  - by Jonathan

  I have a logon script that I want to be run when users login to remote desktop on my WinServer2008r2 box. I know I can do this client-side (in the RemoteDesktopClient "Run Program" options) but would rather it be enforced server-side. If I assign the logon script to a GPO, the script will be run whenever the user logs into their local PC.
