• Upgrading Oracle Enterprise Manager: 12c to 12c Release 2

  - by jorge_neidisch

  1 - Download the OEM 12c R2. It can be downloaded here: http://www.oracle.com/technetwork/oem/grid-control/downloads/index.html  Note: it is a set of three huge zips. 2 - Unzip the archives 3 - Create a directory (as the oem-owner user) where the upgraded Middleware should be installed. For instance: $ mkdir /u01/app/oracle/Middleware12cR2 4 - Back up OMS (Middleware home and inventory), Management Repository and Software Library. http://docs.oracle.com/cd/E24628_01/doc.121/e24473/ha_backup_recover.htm#EMADM10740 5 - Ensure that the Management tables don't have snapshots:  SQL> select master , log_table from all_mview_logs where log_owner='<EM_REPOS_USER>If there are snapshots drop them:  SQL> Drop snapshot log on <master> 6 - Copy emkey  from existing OMS:  $ <OMS_HOME>/bin/emctl config emkey -copy_to_repos [-sysman_pwd <sysman_pwd>]To verify whether the emkey is copied, run the following command: $ <OMS_HOME>/bin/emctl status emkeyIf the emkey is copied, then you will see the following message:The EMKey  is configured properly, but is not secure.Secure the EMKey by running "emctl config emkey -remove_from_repos". 7 - Stop the OMS and the Agent $ <OMS_HOME>/bin/emctl stop oms $ <AGENT_HOME>/bin/emctl stop agent 8 - from the unzipped directory, run $ ./runInstaller 8a - Follow the wizard: Email / MOS; Software Updates: disable or leave empty. 8b - Follow the wizard:  Installation type: Upgrade -> One System Upgrade. 8c - Installation Details: Middleware home location: enter the directory created in step 3. 8d - Enter the DB Connections Details. Credentials for SYS and SYSMAN. 8e - Dialog comes: Stop the Job Gathering: click 'Yes'. 8f- Warning comes: click 'OK'. 8g - Select the plugins to deploy along with the upgrade process 8h- Extend Weblogic: enter the password (recommended, the same password for the SYSMAN user). A new directory will be created, recommended: /u01/app/oracle/Middleware12cR2/gc_inst 8i - Let the upgrade proceed by clicking 'Install'. 8j - Run the following script (as root) and finish the 'installation':  $ /u01/app/oracle/Middleware12R2/oms/allroot.sh 9 - Turn on the Agent:  $ <AGENT_HOME>/bin/emctl start agent  Note that the $AGENT_HOME might be located in the old Middleware directory:  $ /u01/app/oracle/Middleware/agent/agent_inst/bin/emctl start agent 10 - go to the EM UI. Select the WebLogic Target and choose the option "Refresh WebLogic Domain" from the menu. 11 - Update the Agents: Setup -> Manage Cloud Control -> Upgrade Agents -> Add (+) Note that the agents may take long to show up. ... and that's it! Or that should be it !

• Come up with a real-world problem in which only the best solution will do (a problem from Introduction to algorithms) [closed]

  - by Mike

  EDITED (I realized that the question certainly needs a context) The problem 1.1-5 in the book of Thomas Cormen et al Introduction to algorithms is: "Come up with a real-world problem in which only the best solution will do. Then come up with one in which a solution that is “approximately” the best is good enough." I'm interested in its first statement. And (from my understanding) it is asked to name a real-world problem where only the exact solution will work as opposed to a real-world problem where good-enough solution will be ok. So what is the difference between the exact and good enough solution. Consider some physics problem for example the simulation of the fulid flow in the permeable medium. To make this simulation happen some simplyfing assumptions have to be made when deriving a mathematical model. Otherwise the model becomes at least complex and unsolvable. Virtually any particle in the universe has its influence on the fluid flow. But not all particles are equal. Those that form the permeable medium are much more influental than the ones located light years away. Then when the mathematical model needs to be solved an exact solution can rarely be found unless the mathematical model is simple enough (wich probably means the model isn't close to reality). We take an approximate numerical method and after hours of coding and days of verification come up with the program or algorithm which is a solution. And if the model and an algorithm give results close to a real problem by some degree that is good enough soultion. Its worth noting the difference between exact solution algorithm and exact computation result. When considering real-world problems and real-world computation machines I believe all physical problems solutions where any calculations are taken can not be exact because universal physical constants are represented approximately in the computer. Any numbers are represented with the limited precision, at least limited by amount of memory available to computing machine. I can imagine plenty of problems where good-enough, good to some degree solution will work, like train scheduling, automated trading, satellite orbit calculation, health care expert systems. In that cases exact solutions can't be derived due to constraints on computation time, limitations in computer memory or due to the nature of problems. I googled this question and like what this guy suggests: there're kinds of mathematical problems that need exact solutions (little note here: because the question is taken from the book "Introduction to algorithms" the term "solution" means an algorithm or a program, which in this case gives exact answer on each input). But that's probably more of theoretical interest. So I would like to narrow down the question to: What are the real-world practical problems where only the best (exact) solution algorithm or program will do (but not the good-enough solution)? There are problems like breaking of cryptographic ciphers where only exact solution matters in practice and again in practice the process of deciphering without knowing a secret should take reasonable amount of time. Returning to the original question this is the problem where good-enough (fast-enough) solution will do there's no practical need in instant crack though it's desired. So the quality of "best" can be understood in any sense: exact, fastest, requiring least memory, having minimal possible network traffic etc. And still I want this question to be theoretical if possible. In a sense that there may be example of computer X that has limited resource R of amount Y where the best solution to problem P is the one that takes not more than available Y for inputs of size N*Y. But that's the problem of finding solution for P on computer X which is... well, good enough. My final thought that we live in a world where it is required from programming solutions to practical purposes to be good enough. In rare cases really very very good but still not the best ones. Isn't it? :) If it's not can you provide an example? Or can you name any such unsolved problem of practical interest?

• Are there any good Java/JVM libraries for my Expression Tree architecture?

  - by Snuggy

  My team and I are developing an enterprise-level application and I have devised an architecture for it that's best described as an "Expression Tree". The basic idea is that the leaf nodes of the tree are very simple expressions (perhaps simple values or strings). Nodes closer to the trunk will get more and more complex, taking the simpler nodes as their inputs and returning more complex results for their parents. Looking at it the other way, the application performs some task, and for this it creates a root expression. The root expression divides its input into smaller units and creates child expressions, which when evaluated it can use to build it's own result. The subdividing process continues until the simplest leaf nodes. There are two very important aspects of this architecture: It must be possible to manipulate nodes of the tree after it is built. The nodes may be given new input values to work with and any change in result for that node needs to be propagated back up the tree to the root node. The application must make best use of available processors and ultimately be scalable to other computers in a grid or in the cloud. Nodes in the tree will often be updating concurrently and notifying other interested nodes in the tree when they get a new value. Unfortunately, I'm not at liberty to discuss my actual application, but to aid understanding a little bit, you might imagine a kind of spreadsheet application being implemented with a similar architecture, where changes to cells in the table are propagated all over the place to other cells that need the result. The spreadsheet could get so massive that applying multi-core multi-computer distributed system to solve it would be of benefit. I've got my prototype "Expression Engine" working nicely on a single multi-core PC but I've started to run into a few concurrency issues (as expected because I haven't been taking too much care so far) so it's now time to start thinking about migrating the Engine to a more robust library, and that leads to a number of related questions: Is there any precedent for my "Expression Tree" architecture that I could research? What programming concepts should I consider. I realise this approach has many similarities to a functional programming style, and I'm already aware of the concepts of using futures and actors. Are there any others? Are there any languages or libraries that I should study? This question is inspired by my accidental discovery of Scala and the Akka library (which has good support for Actors, Futures, Distributed workloads etc.) and I'm wondering if there is anything else I should be looking at as well?

• What do you need to know to be a world-class master software developer? [closed]

  - by glitch

  I wanted to bring up this question to you folks and see what you think, hopefully advise me on the matter: let's say you had 30 years of learning and practicing software development in front of you, how would you dedicate your time so that you'd get the biggest bang for your buck. What would you both learn and work on to be a world-class software developer that would make a large impact on the industry and leave behind a legacy? I think that most great developers end up being both broad generalists and specialists in one-two areas of interest. I'm thinking Bill Joy, John Carmack, Linus Torvalds, K&R and so on. I'm thinking that perhaps one approach would be to break things down by categories and establish a base minimum of "software development" greatness. I'm thinking: Operating Systems: completely internalize the core concepts of OS, perhaps gain a lot of familiarity with an OSS one such as Linux. Anything from memory management to device drivers has to be complete second nature. Programming Languages: this is one of those topics that imho has to be fully grokked even if it might take many years. I don't think there's quite anything like going through the process of developing your own compiler, understanding language design trade-offs and so on. Programming Language Pragmatics is one of my favorite books actually, I think you want to have that internalized back to back, and that's just the start. You could go significantly deeper, but I think it's time well spent, because it's such a crucial building block. As a subset of that, you want to really understand the different programming paradigms out there. Imperative, declarative, logic, functional and so on. Anything from assembly to LISP should be at the very least comfortable to write in. Contexts: I believe one should have experience working in different contexts to truly be able to appreciate the trade-offs that are being made every day. Embedded, web development, mobile development, UX development, distributed, cloud computing and so on. Hardware: I'm somewhat conflicted about this one. I think you want some understanding of computer architecture at a low level, but I feel like the concepts that will truly matter will be slightly higher level, such as CPU caching / memory hierarchy, ILP, and so on. Networking: we live in a completely network-dependent era. Having a good understanding of the OSI model, knowing how the Web works, how HTTP works and so on is pretty much a pre-requisite these days. Distributed systems: once again, everything's distributed these days, it's getting progressively harder to ignore this reality. Slightly related, perhaps add solid understanding of how browsers work to that, since the world seems to be moving so much to interfacing with everything through a browser. Tools: Have a really broad toolset that you're familiar with, one that continuously expands throughout the years. Communication: I think being a great writer, effective communicator and a phenomenal team player is pretty much a prerequisite for a lot of a software developer's greatness. It can't be overstated. Software engineering: understanding the process of building software, team dynamics, the requirements of the business-side, all the pitfalls. You want to deeply understand where what you're writing fits from the market perspective. The better you understand all of this, the more of your work will actually see the daylight. This is really just a starting list, I'm confident that there's a ton of other material that you need to master. As I mentioned, you most likely end up specializing in a bunch of these areas as you go along, but I was trying to come up with a baseline. Any thoughts, suggestions and words of wisdom from the grizzled veterans out there who would like to share their thoughts and experiences with this? I'd really love to know what you think!

• The long road to bug-free software

  - by Tony Davis

  The past decade has seen a burgeoning interest in functional programming languages such as Haskell or, in the Microsoft world, F#. Though still on the periphery of mainstream programming, functional programming concepts are gradually seeping into the imperative C# language (for example, Lambda expressions have their root in functional programming). One of the more interesting concepts from functional programming languages is the use of formal methods, the lofty ideal behind which is bug-free software. The idea is that we write a specification that describes exactly how our function (say) should behave. We then prove that our function conforms to it, and in doing so have proved beyond any doubt that it is free from bugs. All programmers already use one form of specification, specifically their programming language's type system. If a value has a specific type then, in a type-safe language, the compiler guarantees that value cannot be an instance of a different type. Many extensions to existing type systems, such as generics in Java and .NET, extend the range of programs that can be type-checked. Unfortunately, type systems can only prevent some bugs. To take a classic problem of retrieving an index value from an array, since the type system doesn't specify the length of the array, the compiler has no way of knowing that a request for the "value of index 4" from an array of only two elements is "unsafe". We restore safety via exception handling, but the ideal type system will prevent us from doing anything that is unsafe in the first place and this is where we start to borrow ideas from a language such as Haskell, with its concept of "dependent types". If the type of an array includes its length, we can ensure that any index accesses into the array are valid. The problem is that we now need to carry around the length of arrays and the values of indices throughout our code so that it can be type-checked. In general, writing the specification to prove a positive property, even for a problem very amenable to specification, such as a simple sorting algorithm, turns out to be very hard and the specification will be different for every program. Extend this to writing a specification for, say, Microsoft Word and we can see that the specification would end up being no simpler, and therefore no less buggy, than the implementation. Fortunately, it is easier to write a specification that proves that a program doesn't have certain, specific and undesirable properties, such as infinite loops or accesses to the wrong bit of memory. If we can write the specifications to prove that a program is immune to such problems, we could reuse them in many places. The problem is the lack of specification "provers" that can do this without a lot of manual intervention (i.e. hints from the programmer). All this might feel a very long way off, but computing power and our understanding of the theory of "provers" advances quickly, and Microsoft is doing some of it already. Via their Terminator research project they have started to prove that their device drivers will always terminate, and in so doing have suddenly eliminated a vast range of possible bugs. This is a huge step forward from saying, "we've tested it lots and it seems fine". What do you think? What might be good targets for specification and verification? SQL could be one: the cost of a bug in SQL Server is quite high given how many important systems rely on it, so there's a good incentive to eliminate bugs, even at high initial cost. [Many thanks to Mike Williamson for guidance and useful conversations during the writing of this piece] Cheers, Tony.

• Webcast On-Demand: Building Java EE Apps That Scale

  - by jeckels

  With some awesome work by one of our architects, Randy Stafford, we recently completed a webcast on scaling Java EE apps efficiently. Did you miss it? No problem. We have a replay available on-demand for you. Just hit the '+' sign drop-down for access.Topics include: Domain object caching Service response caching Session state caching JSR-107 HotCache and more! Further, we had several interesting questions asked by our audience, and we thought we'd share a sampling of those here for you - just in case you had the same queries yourself. Enjoy! What is the largest Coherence deployment out there? We have seen deployments with over 500 JVMs in the Coherence cluster, and deployments with over 1000 JVMs using the Coherence jar file, in one system. On the management side there is an ecosystem of monitoring tools from Oracle and third parties with dashboards graphing values from Coherence's JMX instrumentation. For lifecycle management we have seen a lot of custom scripting over the years, but we've also integrated closely with WebLogic to leverage its management ecosystem for deploying Coherence-based applications and managing process life cycles. That integration introduces a new Java EE archive type, the Grid Archive or GAR, which embeds in an EAR and can be seen by a WAR in WebLogic. That integration also doesn't require any extra WebLogic licensing if Coherence is licensed. How is Coherence different from a NoSQL Database like MongoDB? Coherence can be considered a NoSQL technology. It pre-dates the NoSQL movement, having been first released in 2001 whereas the term "NoSQL" was coined in 2009. Coherence has a key-value data model primarily but can also be used for document data models. Coherence manages data in memory currently, though disk persistence is in a future release currently in beta testing. Where the data is managed yields a few differences from the most well-known NoSQL products: access latency is faster with Coherence, though well-known NoSQL databases can manage more data. Coherence also has features that well-known NoSQL database lack, such as grid computing, eventing, and data source integration. Finally Coherence has had 15 years of maturation and hardening from usage in mission-critical systems across a variety of industries, particularly financial services. Can I use Coherence for local caching? Yes, you get additional features beyond just a java.util.Map: you get expiration capabilities, size-limitation capabilities, eventing capabilites, etc. Are there APIs available for GoldenGate HotCache? It's mostly a black box. You configure it, and it just puts objects into your caches. However you can treat it as a glass box, and use Coherence event interceptors to enhance its behavior - and there are use cases for that. Are Coherence caches updated transactionally? Coherence provides several mechanisms for concurrency control. If a project insists on full-blown JTA / XA distributed transactions, Coherence caches can participate as resources. But nobody does that because it's a performance and scalability anti-pattern. At finer granularity, Coherence guarantees strict ordering of all operations (reads and writes) against a single cache key if the operations are done using Coherence's "EntryProcessor" feature. And Coherence has a unique feature called "partition-level transactions" which guarantees atomic writes of multiple cache entries (even in different caches) without requiring JTA / XA distributed transaction semantics.

• Zscaler. Certs, cookies, and port 80 traffic

  - by 54's_lol

  So I work at HQ for a large company that shall remain nameless. We use Zscaler and I had to roll out a 2048 cert per zscaler's request. People around me at work dont understand the technology and think that the cert's are what is allowing internet connectivity. From my understanding(and please chime in) is the cookie located C:\Users\$$$$$$4$$\AppData\Roaming\Macromedia\Flash Player#SharedObjects\Q3JQJQJV\gateway.zscaler.net\zscaler.swf here that gets created when you provide your creds the first time you use the browser. The cert's are just simply a way of inspecting the SSL traffic as zscaler had no way of doing this before without them. They are essentially using the classic MITM attack to parse your SSL traffic. Gmail is smart enough to recognize this as you get a warning. My question is this, is there a product or service that I can use to verify my web browser when at home(I.E. off company network) isn't still getting routed to zscaler's cloud? If i do a tracert that will work fine. It's the port 80 and 443 web traffic zscaler and my company is after. I would like to verify that when I'm off their premise that my web traffic is using only my isp and the path to whatever content I'm searching for. Do the cert's i'm pushing and browser authentication do something behind the curtain that forces web traffic to get routed to zscaler? I searched quite a bit and would very much like to know if I'm ever off company scrutiny. I do know zscaler offers the service to force the scenario im asking about. Can I prove how my web traffic is getting routed? Thanks for any insight. I've been a fan for a long time and your guy's kung fu is very strong:-)

• Debian Apache2 and SSL

  - by Topher Fangio

  Hello all, I recently took over a server that is using Apache2 with SSL. I have setup a new server to which I am migrating all of the old websites so that we can more easily scale (it's a cloud server) and so that I can set everything up correctly (or at least with some sort of convention). I have read quite a few articles on setting up Apache2 and SSL with virtual hosts, but I'm a bit confused because all of the examples show three files and I only seem to have two. To compound the problem, they are all named differently (do the file extensions actually make a difference?). The examples show something to this effect: <VirtualHost X.X.X.X:443> ServerAlias something.mydomain.com ServerAdmin [email protected] DocumentRoot /var/www/project/client/site SSLEngine on SSLCertificateFile /etc/ssl/certs/mydomain-cert.pem SSLCertificateKeyFile /etc/ssl/private/mydomain-key.pem SSLCertificateChainFile /etc/ssl/certs/mydomain-ca.crt </VirtualHost> However, the files I have are: _.mydomain.com.crt gd_bundle.crt It is a wildcard certificate that we purchased through GoDaddy I believe. I believe that the first file is the actual certificate file and the gd_bundle.crt is the chain file, but that leaves me without a key file. There is also a random mydomain.csr file lying around on the old server, but it wasn't one of the files bundled with the download from GoDaddy, so I'm not really sure as to what it is. Any help in figuring out what I need to do would be greatly appreciated. I am software developer, so I know my way around computers, but I have only dabbled in server setup/maintenance. Much Thanks!

• Indefinite hang when restoring SQL 2005 database on a SQL 2008 server in EC2

  - by erinloy

  I'm trying to restore a 25 GB database backup taken from a Windows 2003/SQL 2005 machine to a Windows 2008/SQL 2008 machine in the Amazon EC2 cloud, using a .bak file and the SQL Management Studio. SQL Management Studio reports the restore reaches 100% complete, and then just hangs indefinitely (24+ hours) using a lot of CPU, until I restart the SQL Server service. Upon restart, SQL again uses a lot of CPU activity for what seems to be an indefinite amount of time, but the DB never comes online. Here are some details: - I have created two EBS volumes, one for DATA and one for LOGS, and I have set the default directories in SQL Server to the \DATA and \LOG directory on these respective volumes. (I wonder if the issue could be related to this, but the DB is too big to restore on the root drive.) - I have given the SQL Server user group full access to these directories. - The server can create a new empty test DB in these directories just fine, and can backup and restore the test DB. - I have tried both restoring of a .bak file and attaching directly to copies of the original .mdf/.ldf files, and the result is the same in both cases. - Both the .bak restore and the .mdf/.ldf attach occur from/to the EBS volumes. - I've also tried the above via SQL script, and "WITH RECOVERY", with no difference in the result, just less UI. - The backup contains two full text indexes. - I have to use "WITH MOVE" for most of the files in the backup. - There's nothing wrong with the backup or .mdf/.ldf files, as this works just fine on a Windows 2003/SQL 2005 machine in the Amazon EC2, but not Windows 2008/SQL 2008. - The DB is NOT marked as "Restoring" in the SQL Management Studio - it is just listed as a normal database, but throws errors when I try to do anything with it (expand the object browser tree, view properties, etc.) Any ideas?

• Memcached session manager in Azure: Connection gets forcibly closed

  - by Edgar Pérez

  I am using Memcached Session Manager to handle Tomcat sessions in non-sticky mode. My deployment in Azure consists of a Worker Role with two instances which connect to an Azure VM running my Memcached server. Everything works pretty well, my session is persisted and retrieved by any of the two instances transparently. The problem arises when the session is idle for about 4 minutes; everything points out that the Azure Loadbalancer is closing the spymemcached connection to the VM after some period of inactivity. My MSM configuration is this: <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:my-azure-vm.cloudapp.net:11211" sticky="false" sessionBackupAsync="false" sessionBackupTimeout="10000" lockingMode="uriPattern:/path1|/path2" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js|ttf|eot|svg|woff)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" customConverter="de.javakaffee.web.msm.serializer.kryo.HibernateCollectionsSerializerFactory"/> The stacktrace printed by the spymemcached client is this: INFO net.spy.memcached.MemcachedConnection: Reconnecting due to exception on {QA sa=/10.194.132.206:13000, #Rops=1, #Wops=0, #iq=0, topRop=net.spy.memcached.protocol.binary.StoreOperationImpl@1d95da8, topWop=null, toWrite=0, interested=1} java.io.IOException: An existing connection was forcibly closed by the remote host at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(Unknown Source) at sun.nio.ch.IOUtil.readIntoNativeBuffer(Unknown Source) at sun.nio.ch.IOUtil.read(Unknown Source) at sun.nio.ch.SocketChannelImpl.read(Unknown Source) at net.spy.memcached.MemcachedConnection.handleReads (MemcachedConnection.java:303) at net.spy.memcached.MemcachedConnection.handleIO (MemcachedConnection.java:264) at net.spy.memcached.MemcachedConnection.handleIO (MemcachedConnection.java:184) at net.spy.memcached.MemcachedClient.run(MemcachedClient.java:1298) Given this idle time limitation in Azure, is there any other way to make MSM work in the azure cloud?

• Implement QoS/Bandwidth Management or Upgrade Bandwidth?

  - by Michael

  A question that I'm faced with currently. Here's my setup: Cisco ASA 5510 15Mbps Internet Connection @ $1350/month The bandwidth was originally meant for 35-45 people but we've grown quite quickly to roughly 60-65 people. Needless to say, when I check bandwidth logs it's almost always spiked at 15Mbps. I did use Wireshark to do some poking around to see what was hogging up our bandwidth but with everything running through CDNs and Cloud Services it proved difficult to get a good grasp of where our bandwidth was going. So the question is do I ONLY implement bandwidth management through ASA OR upgrade the Internet to 50Mbps ($1600/month) and then implement bandwidth management through ASA? Any suggestions on how to segment the 15Mbps connection if we decided ONLY to go with the bandwidth management solution? Thanks. UPDATE 1 Installed PRTG and used packet content to monitor the traffic. As I suspected still pretty vague. My Top Connections include the following: a204-2-160-16.deploy.akamaitechnologies.com ec2-50-16-212-159.compute-1.amazonaws.com a204-2-160-48.deploy.akamaitechnologies.com a72-247-247-133.deploy.akamaitechnologies.com mediaserver-sv5-t1-1.pandora.com Other than the Pandora destination, the rest doesn't tell me much on how to properly control the bandwidth. Any thoughts or suggestions? Thanks. M

• TeamCity EC2 Integration via ISA Server

  - by Tim Long

  I have a TeamCity server which is actually installed on SBS 2003 Premium with ISA Server (firewall/proxy) installed. My ADSL connection has multiple IP addresses, which all resolve directly to my SBS external NIC. The NIC is therefore multi-homed and I have allocated one of the IP addresses specifically to TeamCity. In ISA, I've created an access rule to allow the traffic in. I can access my TeamCity server externally and view the web interface, that all works fine. I want to use the Amazon EC2 integration in TeamCity to launch build agents 'in the cloud'. The problem I am having is that when the agent starts, it sees the server and registers, then just sits there waiting. On the server side, the agent appears as 'disconnected'. Examining the settings, the agent's IP address appears to be that of the external NIC. What I think might be happening is that the traffic is undergoing Network Address Translation (NAT) so that TeamCity always thinks the agent is locally installed and therefore can't communicate with the actual remote agent. This seems to happen even though I have a permanent static IP address dedicated to TeamCity. So, the question is this. How can I make traffic to a specific IP address pass through the ISA server un-NATted?

• 16-bit MS-DOS Subsystem: csrss.exe

  - by Wesley

  Hi all, I just booted up my Samsung N120 netbook (with Windows XP Home SP3) and a dialog box came up with a command prompt window behind it. The dialog box is titled 16 bit MS-DOS Subsystem and the message is as follows: C:\DOCUME~1\SAMSUNG\csrss.exe The NTVDM CPU has encountered an illegal instruction. CS:0544 IP:0117 OP:63 00 64 00 34 Choose 'Close' to terminate the application. This only started on my most recent boot-up. One thing to note is that when I downloaded the Dropbox installer and opened it up, Panda Cloud Antivirus detected a suspicious file, which was csrss.exe and "neutralized it." However, an actual virus or trojan was not detected immediately before the file was detected and neutralized. Just under two weeks ago, a trojan and two viruses were detected for some odd reason. (I only went to website I knew and I do not torrent or browse adult sites.) Anyhow, the two viruses came up in temporary files and the trojan was "neutralized." Anyways, the main question is: How can I repair the csrss.exe file such that Windows XP starts up properly? A screenshot could be posted upon request. Thanks in advance!

• Amazon AWS EC2 + Puppet, get Puppet to know AWS instance tags

  - by Piotr Jasiulewicz

  I am having a problem with my AWS deployment, fairly new to AWS and Puppet. So coming to my question - can you distinguish puppet nodes with AWS machine tags or CNAME domains? A little background about the plan: have multiple clusters of machines, one php cluster, one legacy php cluster, one java cluster, one perl cluster control configuration with puppet - still pretty new to puppet but as a developer I like the idea of being able to version control configuration of servers have autoscaling enabled on those clusters - obviously the main benefit of the cloud that makes the much hight cost when it comes to any reasonable performance worth it (those amazon machines are slower than my phone...) deployment controlled by Capistrano, this makes things a lot easier So in AWS you get those super nasty public/private machine dns's... no way you can identify machines on those. In order to easer the problem, seams like AWS want's you to tag everything - so I did. Found a script that makes a CNAME record for each machine with the tag "ShortName" thanks to the Route53 API. Every machine has a ShortName tag that becomes its CNAME, unfortunately puppet still resolves the private dns name. I'd like to have node 'perl-cluster'{} in puppet, anyone any clue ho to achieve this? Thanks

• How do I fix issue causing "incomplete startup packet" log message trying to implement replication in Postgresql?

  - by colour me brad

  I've got two cloud servers running Ubuntu 13.04 and PostgreSQL 9.2. I've primarily used this blog post to aid me in setting things up. However, to do the initial database dump to the slave I'm using pg_start_backup/pg_stop_backup strategy used in this other blog post. I've read through the docs and postgres wikis as well. I ran into several problems I was able to solve, but I can't get past this wretched "the database is starting up" failure. I'm not sure if seeing "cp: cannot stat '/var/lib/postgresql/9.2/archive/00000001000000000000003A': No such file or directory" after "consistent recover state reached" is normal or the first sign of a problem. The searching I've done on "the database is starting up" and "incomplete startup packet" tells me that something is sending empty TCP packets to the slave. The only thing that even knows about the slave is the master, so I'm not sure why it's sending empty packets... Has anyone worked with this and have an idea what might be going wrong? The postgres log on the slave looks like so: 2013-08-26 13:01:38 CDT LOG: entering standby mode 2013-08-26 13:01:38 CDT LOG: restored log file "000000010000000000000039" from archive 2013-08-26 13:01:38 CDT LOG: incomplete startup packet 2013-08-26 13:01:39 CDT LOG: redo starts at 0/39000020 2013-08-26 13:01:39 CDT LOG: consistent recovery state reached at 0/390000E0 cp: cannot stat '/var/lib/postgresql/9.2/archive/00000001000000000000003A': No such file or directory 2013-08-26 13:01:39 CDT LOG: streaming replication successfully connected to primary 2013-08-26 13:01:39 CDT FATAL: the database system is starting up 2013-08-26 13:01:39 CDT FATAL: the database system is starting up 2013-08-26 13:01:40 CDT FATAL: the database system is starting up 2013-08-26 13:01:40 CDT FATAL: the database system is starting up 2013-08-26 13:01:41 CDT FATAL: the database system is starting up 2013-08-26 13:01:42 CDT FATAL: the database system is starting up 2013-08-26 13:01:42 CDT FATAL: the database system is starting up 2013-08-26 13:01:43 CDT FATAL: the database system is starting up 2013-08-26 13:01:43 CDT FATAL: the database system is starting up 2013-08-26 13:01:44 CDT FATAL: the database system is starting up 2013-08-26 13:01:44 CDT FATAL: the database system is starting up 2013-08-26 13:01:44 CDT LOG: incomplete startup packet 2013-08-26 13:03:27 CDT FATAL: the database system is starting up 2013-08-26 13:03:27 CDT FATAL: the database system is starting up 2013-08-26 13:03:30 CDT FATAL: the database system is starting up 2013-08-26 13:03:30 CDT FATAL: the database system is starting up thanks! brad

• Active Directory Domain Services - Network Name Cannot be Found

  - by Arief

  I have really weird problem that I could not explain. I am trying to redirect all users home folder to the new server. I have copied all the files including the permissions to the new server. All I need to do is to update the user profile for home folder by changing the server name. However, I got this message when I enter the new server name: My server that serving as AD can resolve the name by ping and nslookup of the server name. The only thing that I don't understand why the MMC cannot resolve the name. I did change with the IP Address and I still get the same error message. Thank you so much for your help. UPDATE: I know what seems to be a problem, but I don't know how to fix it. The new server that will serve all Home folder is actually sitting in the cloud with different IP Address as the Domain Controller. The Domain Controller is sitting locally in the office with 10.0.0.0/24 IP Addresses. The new server that is sitting in on Data Centre is on 172.10.10.10/24 IP Addresses. The static route has been set up on both end, and the DNS as well. I believe this is the issue. Does anyone how to overcome this situation? Thank you.

• Can IIS (Ideally Azure) do SSL Proxying?

  - by Acoustic

  My team has been asked to add a new feature to a project we're working on, and none of can find authoritative details on whether it's possible with Windows/IIS. The short of it is that we're hoping to have customers update their DNS with a CNAME record to point their website to our server instead of theirs (they why's are trivial - it's what the app does on behalf of your site). We're using a reverse proxy with several custom modules to serve particular content from the original servers. So far everything works perfectly until we encounter SSL. Is there a way to have IIS serve up an SSL certificate from another server? In other words, is there a way to be a trusted man in the middle? I'm hoping that's possible so that we don't have to require all our clients to re-issue their SSL certs. Frankly, we don't want to have to manage hundreds of certs. I'd also like to avoid a UCC situation if there's a way to because it seems to require re-creating the cert each time a client is added. So, any pointers on proxying/hosting SSL (or even dynamic SSL hosting like http://www.globalsign.com/cloud/) would be appreciated.
