  • How can I enable anonymous access to a Samba share under ADS security mode?

    - by hemp
    I'm trying to enable anonymous access to a single service in my Samba config. Authorized user access is working perfectly, but when I attempt a no-password connection, I get this message: Anonymous login successful Domain=[...] OS=[Unix] Server=[Samba 3.3.8-0.51.el5] tree connect failed: NT_STATUS_LOGON_FAILURE The message log shows this error: ... smbd[21262]: [2010/05/24 21:26:39, 0] smbd/service.c:make_connection_snum(1004) ... smbd[21262]: Can't become connected user! The smb.conf is configured thusly: [global] security = ads obey pam restrictions = Yes winbind enum users = Yes winbind enum groups = Yes winbind use default domain = true valid users = "@domain admins", "@domain users" guest account = nobody map to guest = Bad User [evilshare] path = /evil/share guest ok = yes read only = No browseable = No Given that I have 'map to guest = Bad User' and 'guest ok' specified, I don't understand why it is trying to "become connected user". Should it not be trying to "become guest user"?

  • RHEL kickstart with external DVDrom drive

    - by AndyM
    HI I've an old Dell poweredge server with an CDROM drive. I've attached a USB DVDROM and USB stick with my ks.cfg on so I can install RHEL from DVD not loads of CDs :-) I can boot from the RHEL media in DVDROM and point the installer to the USB ks.cfg. This works but the ks.cfg script has the cdrom keyword in it. The install then stops and asks for the RHEL media to be in the CDROM drive not the DVDROM. How can I change the ks.cfg so it uses the external DVDROM for the install media not servers builtin cdrom drive ? I know I can go and rebuild my DVD image to include the ks.cfg , but this is an extra step I dont want to do if I have to. Regards Andy

  • Remote Desktop over SSH SOCKS proxy to bypass firewall

    - by scrumpyjack
    Hi folks, I'm trying to connect to a Windows server from my Mac using RDC2.1 for Mac. The problem is the server I need to connect to is guarded by the evil dragon - IP-based access control on a completely separate network. I have an IP I can get in on, but it's at my office (i.e. a completely separate network). Because that network isn't set up for VPN, I've set up a SOCKS proxy through an SSH tunnel (which is all working fine). (SSH proxy) Me (on my Mac) ----------> Office Linux box ----> Windows server (home network) (office network) (other network) From my Linux server in my office (the SSH server) I can telnet to port 3389 on the Windows server, no problem. But from my Mac I can't get so much as a squeak out of it. Any ideas?

  • Setup secure shared hosting (Apache, PHP, MySQL)

    - by Apaz
    So I'm setting up a shared hosting with Apache, PHP, MySQL and the biggest question mark is how to do with PHP, since there is a million options out there how to configure it securely. The plan is: Chroot for MySQL (built in support for chroot) Chroot for Apache (mod_security) Each user executing their PHP-scripts as their own user (see below) Set open_basedir Disable all "evil" php-functions (allow_url_fopen, system, exec, and so on) Ive looked at suexec and suphp but they seems very slow; http://blog.stuartherbert.com/php/2007/12/18/using-suexec-to-secure-a-shared-server/ http://blog.stuartherbert.com/php/2008/01/18/using-suphp-to-secure-a-shared-server/ So I've looked some more and found some other solutions: apache2-mpm-itk + mod_php(?) mod_fcgid + php-fpm mod_fastcgi + php-fpm Ive tried a simple setup with mod_fastcgi + php-fpm and it seems to work, runs as correct user and so on, but the protection against directory traveling is still open_basedir(?) One solution for that could be to use php-fpm's chroot option, but that causes a lot of other issues like domain name resolver does not work sending mail does not work Tips?

  • Bind telnetd to specific IP on AIX 5.3?

    - by Sama
    Is it possible to bind telnetd to a specific IP on AIX 5.3? I know telnet is evil. Unfortunately, we have to have it listening on one interface for a specific application, but I want to make sure that's the only interface/IP that it's listening on. I have been searching all over the net and have found some advice for Linux, but it doesn't appear to be applicable to AIX. Full disclosure: I am not the server admin, but I am working closely with them and am familiar with *nix. Add: This is an internal server, which is connected to two different vlans. This is NOT connected to the Internet(!).

  • Same command on multiple servers

    - by w00t
    Hello everyone. I'm just wondering if there is any fellow sysadmin with the need to execute one command on multiple servers. If so, what technique are you using? I have grown tired to ssh-ing to 3-5 servers and executing the same thing over and over again, so I'm thinking to make my life easier. Also, I think I should create keys so I don't have to enter passwords anymore (though I'm using root). After 2 years of doing this, I kind of developed a laziness. I googled it up, I know about cssh, pssh, tentakel (this one seems cool), and the more pro-genre - Puppet (of which I just heard of, didn't invest the time to read the docs). BTW, I'm using XP+putty, so if there is any putty-cool-thingy available, that's welcome too. If not, I can always ssh to one server and from there start my rest-of-the-servers-conquest :) *evil* Hit me up. Thanks.

  • some keyboard keys not working properly

    - by surfmadpig
    I'm using Windows 7. All of a sudden, a couple of hours ago, this happened: My keyboard number keys [above the letters] stopped working properly, both as numbers and as symbols. Only 5 and 6 are functional. Also, I've noticed that the End key isn't working either, and perhaps a couple more from that group. I'm pretty sure it has something to do with those evil Sticky Keys/Filter Keys/ whatever those ease of access things are, BUT I've turned off all the ease of access keyboard options and nothing has changed. Is it possible that something is still turned on while I unchecked it? Are the on/off checkboxes to control WHEN it happens or IF it happens? I also tried rebooting and uninstalling/reinstalling keyboard from device manager, to no avail. It's certainly a software issue and not a hardware issue, as I've tried another keyboard and the problem persists. And, predictably enough, it's annoying. Any ideas?

  • Windows Filtering Platform not turning off until admin logon. Win2008R2sp1

    - by rjt
    Just installed Windows Server 2008R2 SP1 to see if it would fix this problem, but it didn't. Until an administrator logs onto the domain controller, there are many events that WFP blocked a connection from Server60 to Server60 or Server60 to Server70. Both server60 and server70 are the domain controllers. One the admin logs on, the WFP events stop. The firewall is off by default GPO. Yes, i know that the WFP kicks in during the boot up sequence until the firewall takes over or in my case does not take over (since Vista), but i clearly should not have to autologon to a domain controller and call autolock or something. Example event LEVEL = Information Source = Microsoft Windows Security Auditing EventID = 5152 "Filtering Platform Packet Drop" and its evil twin id = 5157 "Filtering Platform Connection" "The Windows Filtering platform has blocked a connection." Direction %%14593 SourceAddress 192.168.10.60 SourcePort 49677 DestAddress 192.168.10.60 DestPort 389 Protocol 6 FilterRTID 65667 LayerName %%14611 LayerRTID 48 RemoteUserID S-1-0-0 RemoteMachineID S-1-0-0 windows-server-2008-r2 WFP BFE WindowsFilteringPlatform BaseFilteringEngine

  • Files beginning with "._"

    - by Cliff_31
    Sometimes when my wife works on photos in Photoshop on her Mac, what she gives me back are all the photos I took, with their .jpg extensions in place, as well as a set of "ghost" files. That is, for every photo, there is an evil twin whose file name is the same ... except that it begins with "._". Also this ghost file are sort of "grayed-out" and don't open when double clicked. I suspect they are hidden files, (I have set windows to show all hidden files) but what find of hidden file -- on that, I'm clueless. I just delete these files and never have a problem with the photo (.jpg) files, but still I'm dying to know; what are they? Thanks

  • Disable incremental search in firefox (and everything else!)

    - by Alan Curry
    All I find from googling "disable incremental search" is a bunch of people telling me how great incremental search is. It isn't. Firefox has the worst version of it, jumping around and making me lose my place because of a search I haven't even finished typing yet. I don't want the window scrolling up and down without my say-so. It would be nice if I could search with regular expressions, like text search has been done in every non-toy application since ed. But the jumpiness of the window is the overriding concern. How can this evil be defeated?

  • Password Security: Short and Complex versus ‘Short or Lengthy’ and Less Complex

    - by Akemi Iwaya
    Creating secure passwords for our online accounts is a necessary evil due to the huge increase in database and account hacking that occurs these days. The problem though is that no two companies have a similar policy for complex and secure password creation, then factor in the continued creation of insecure passwords or multi-site use of the same password and trouble is just waiting to happen. Ars Technica decided to take a look at multiple password types, how users fared with them, and how well those password types held up to cracking attempts in their latest study. The password types that Ars Technica looked at were comprehensive8, basic8, and basic16. The comprehensive type required a variety of upper-case, lower-case, digits, and symbols with no dictionary words allowed. The only restriction on the two basic types was the number of characters used. Which type do you think was easier for users to adopt and did better in the two password cracking tests? You can learn more about how well users did with the three password types and the results of the tests by visiting the article linked below. What are your thoughts on the matter? Are shorter, more complex passwords better or worse than using short or long, but less complex passwords? What methods do you feel work best since most passwords are limited to approximately 16 characters in length? Perhaps you use a service like LastPass or keep a dedicated list/notebook to manage your passwords. Let us know in the comments!

  • MVP Summit 2011 summary and thoughts: The &ldquo;I hope I don&rsquo;t cross a line and lose my MVP status&rdquo; post

    - by George Clingerman
    I've been wanting to write this post summarizing my thoughts about the MVP summit but have been dragging my feet since it's a very difficult one to write. However seeing Andy (http://forums.create.msdn.com/forums/t/77625.aspx) and Catalin (http://www.catalinzima.com/2011/03/mvp-summit-2011/) and Chris (http://geekswithblogs.net/cwilliams/archive/2011/03/07/144229.aspx) post about it has encouraged me to finally take the plunge. I'm going to have to write carefully though because I'm going to be dancing around a ton of NDA mine fields as well as having to walk the tight-rope of not sending the wrong message or having people read too much into what I'm saying. I want to note that most of what I'm about to say is just based on my observations, they're not thoughts that Microsoft has asked me to pass along and they're not things I heard Microsoft say. It's just me sharing what I think after going to the MVP summit. Let's start off with a short imaginary question and answer session.     Has the App Hub forums and XBLIG management been rather poor by Microsoft? Yes.     Do I think we're going to see changes to that overnight? No.     Will it continue to look bad from the outside? Somewhat. Confusing right? Well that's kind of how things are right now. Lots of confusion. XNA is doing AWESOME. Like, really, really awesome. As a result of that awesomeness, XNA is on three major platforms: Xbox 360, WP7 and PC. This means that internally Microsoft is really excited and invested in the technology. That's fantastic for XNA and really should show you the future the framework has. It's here to stay. So why are Xbox LIVE Indie Game developers feeling so much pain? The ironic thing is that pain is being caused by the success of XNA. When XNA was just a small thing, there was more freedom and more focus. It was just us and them. We were an only child. Now our family has grown and everyone has and wants some time with XNA. This gets XNA pulled in all directions and as it moves onto new platforms, it plays catch up trying to get those platforms up to speed to where Xbox LIVE Indie Games has grown. Forums, documentation, educational content. They all need to be there because Xbox LIVE Indie Games has all of that and more. Along with the catch up in features/documentation/awesomeness there's the catch up that the people on the team have to play. New platforms and new areas of development mean new players and those new guys don't have the history of being around from the beginning. This leads to a lack of understanding at times just how important some things are because they seem so small and insignificant (Rich Text defaulting for new forum profiles would be one things that jumps to mind). If you're not aware that the forums have become more than just a basic Q&A, if you're not aware that they're a central hub to a very active community, then you don't understand why that small change should be prioritized over something else. New people have to get caught up and figure out how to make a framework and central forum site work for everyone it's now serving. So yeah, a lot of our pain this last year has been simply that XNA is doing well and XBLIG is doing well so the focus was shifted to catch other things up. It hurts when a parent seems to not have any time for you and they're spending some much time with your new baby brother. Growing pains. All families and in our case our product family experience it to some degree. I think as WP7 matures we'll see the team figuring out how to give everyone the right amount of attention. While we're talking about some of our growing pains, it is also important to note (although not really an excuse) that the Xbox LIVE Arcade developers complain about many of the same things that we do. If you paid attention to talks and information coming out of GDC 2011, most of the the XBLA guys were saying things that sounded eerily similar to what the XBLIG developers are saying (Scott Nichols from GayGamer.net noticed http://twitter.com/#!/NaviFairyGG/status/43540379206811650). Does this mean we should just accept the status quo since we're being treated exactly the same? No way. However it DOES show that the way we're being treated is no indication of the stability and future of the platform, it's just Microsoft dropping the communication ball on two playing fields. We're not alone and we're not even being treated worse. Not great, but also in a weird way a very good sign. Now on to a few tidbits I think I CAN share from the summit (I'm really crossing my fingers I'm not stepping over some NDA line I shouldn't be). First, I discovered that the XBLIG user base is bigger than I personally had originally estimated. I won't give the exact numbers (although we did beg Microsoft to release some of these numbers so maybe someday?) but it was much larger than my original guestimates and I was pleasantly surprised. Maybe some of you guys had the right number when you were guessing, but I know that mine was much too low. And even MORE importantly the number of users/shoppers is growing at a steady pace as well. Our market is growing! That was fantastic news and really something that I had to share. On to the community manager discussion. It was mentioned. I was mentioned. I blushed. Nothing more to report there than the blush in my cheeks was a light crimson color. If I ever see a job description posted for that position I have a resume waiting in the wings. I can't deny that I think that would be my dream job... ...so after I finished blushing, the MVPs did make it very, very clear that the communication has to improve. Community manager or not the single biggest pain point with the Xbox LIVE Indie Game community has been a lack of communication. I have seen dramatic improvement in the team responding to MVPs and I'm even seeing more communication from them on the forums so I'm hoping that's a long term change. I really think they understood the issue, the problem remains how to open that communication channel in a way that was sustainable. I think they'll get it figured out and hopefully that's sooner rather than later. During the summit, you may have seen me tweeting about how I was "that guy" (http://twitter.com/#!/clingermangw/status/42740432471470081). You also may have noticed that Andy and Catalin both mentioned me in their summit write ups. I may have come on a bit strong while I was there...went a little out of character for myself. I've been agitated for a while with the way things have been and I've been listening to you guys and hearing you guys be agitated. I'm also watching some really awesome indie game developers looking elsewhere and leaving the platform. Some of them we might not have been able to keep even with changes, but others are only leaving because of perceptions and lack of communication from Microsoft. And that pisses me off. And I let Microsoft know that I was pissed off. You made your list and I took that list and verbalized it. I verbalized the hell out of it. [It was actually mentioned that I'm a lot nicer on the forums and in email than I am in person...I felt bad about that, but I couldn't stay silent]. Hopefully it did something guys, I really did try hard to get the message across. Along with my agitation, I also brought some pride. I mentioned several things in person to the team that I was particularly proud of. From people in the community that are doing an awesome job, to the re-launch of XboxIndies that was going on that week and even gamers like Steven Hurdle (http://writingsofmassdeduction.com/) who have purchased one XBLIG every day for over 100 days now. The community is freaking rocking it and I made sure to highlight that. So in conclusion, I'd just like to say hang in there (you know, like that picture of the cat). If you've been worried about investing in Xbox LIVE Indie Games because you think it's on shaky ground. It's not. Dream Build Play being about the Xbox 360 should have helped a little to point that out. The team is really scrambling around trying to figure things out and make improvements all around. There’s quite a few new gals and guys and it's going to take them time to catch up and there are a lot of constantly shifting priorities. We all have one toy, one team and we're fighting for time with it. It's also time for the community to continue spreading our wings and going out on our own more often. The Indie Game Winter Uprising was a fantastic example of that. We took things into our own hands and it got noticed and Microsoft got behind it. They do every time we stand up and do something (look at how many Microsoft employees tweeted, wrote about the re-launch of XboxIndies.com or the support I've gotten from them for my weekly XNA Notes). XNA is here to stay, it's time for us to stop being scared of that and figure out how to make our own games the successes they should be. There's definitely a list of things that need to be fixed, things that should be improved and I think we should definitely keep vocal about that with Microsoft. Keep it short, focused and prioritized. There's also a lot of things we can do ourselves while we're waiting on them to fix and change things. Lots of ways we can compensate for particular weaknesses in the channel. The kind of stuff that we can step up and do ourselves. Do it on our own, you know, the way Indies always do. And I'm really looking forward to watching us do just that.

  • Navigating the Unpredictable Swinging of the Financial Regulation Pendulum

    - by Sylvie MacKenzie, PMP
    Written by Guest Blogger: Maureen Clifford, Sr Product Marketing Manager, Oracle The pendulum of the regulatory clock is constantly in motion, albeit often not in any particular rhythm.  Nevertheless, given what many insurers have been through economically, any movement can send shock waves through critical innovation and operational plans.  As pointed out in Deloitte’s 2012 Global Insurance Outlook, the impact of regulatory reform can cause major uncertainty in the area of costs.  As the reality of increasing government regulations settles in, the change that comes along with it creates more challenges in compliance and ultimately on delivering the optimum return on investment.  The result of this changing environment is a proliferation of compliance projects that must be executed with an already constrained set of resources, budget and time. Insurers are confronted by the need to gain visibility into all of their compliance efforts and proactively manage them. Currently that is very difficult to do as these projects often are being managed by groups across the enterprise and they lack a way to coordinate their efforts and drive greater synergies.  With limited visibility and equally limited resources it is no surprise that reporting on project status and determining realistic completion of these projects is only a dream. As a result, compliance deadlines are missed, penalties are incurred, credibility with key stakeholders and the public is jeopardized and returns and competitive advantage go unrealized. Insurers need to ask themselves some key questions: Do I have “one stop” visibility into all of my compliance efforts?  If not, what can I do to change that? What is top priority and how does that impact my already taxed resources? How can I figure out how to best balance my resources to get these compliance projects done as well as keep key innovation and operational efforts on track? How can ensure that I have all the requisite documentation for each compliance project I undertake? Dealing with complying with regulatory efforts is a necessary evil. Don't let the regulatory pendulum sideline your efforts to generate the greatest return on investment for your key stakeholders.

  • Collaborate 2010: Spotlight on Oracle Content Management

    - by [email protected]
    Excitement is building for the Collaborate conference April 18th through the 22nd. Outside of the event being in Las Vegas, which for me often seems to add to the excitement, there will be a great lineup of Oracle Content Management focused sessions. In fact, there are currently over 30 content management sessions scheduled, and attendees will get to hear from customers, partners, as well as Oracle experts. Attendees should expect to hear a lot about Oracle Content Management 11g at Collaborate 2010. Roel Stalman and Andy MacMillan will kick off these discussions on Monday, April 19th as they present Oracle Content Management's product strategy and roadmap (10:45 - 11:45). Monday's lineup also includes sessions on Oracle Imaging and Process Management (I/PM) 11g and Oracle Forms Recognition (2:30 - 3:30), which were both released in January. For those customers using older versions of I/PM or Stellent IBPM, be sure not to miss the "migrating to I/PM 11g" session on Monday as well (1:15 - 2:15) as this should give you some insight into the migration process. Check out the entire list of Oracle Content Management sessions here. Another focus at Collaborate this year is to discuss the benefits of using Oracle Content Management with Oracle Applications - Oracle E-Business Suite, PeopleSoft, and Siebel - so be sure to check out these sessions too: Accelerating Accounts Payable Processes with Integrated Document Imaging(Monday, April 19th, 3:45 - 4:45)Supercharge Your Siebel Sales and Marketing with Integrated Document Management(Tuesday, April 20th, 2:00 - 3:00)Oracle Enterprise 2.0 for Oracle Applications: The Value of an Integrated E2.0 Platform(Tuesday, April 20th, 3:15 - 4:15)Comprehensive Human Resources Automation with Oracle Content Management(Wednesday, April 21st, 1:00 - 2:00) Collaborate is also the perfect opportunity to meet Oracle executives and product experts. Attendees can sign up for 1 on 1 meetings at the event, and there will be someone representing each Oracle Content Management product. These meetings are probably the best way to get your product questions answered in a face-to-face manner. It seems more and more to me that Oracle Content Management customers are viewing Collaborate as "the" conference to attend each year. I hope you have plans to attend and I will see you there.

  • Nuggets of wisdom?

    - by Bill Karwin
    There are many quotes from famous computer scientists that have become the wisdom that guides our profession. For example: "Premature optimization is the root of all evil in programming." Donald Knuth (citing Hoare's Dictum) "Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?" Brian Kernighan And so on. My question is, what are your favorite words of wisdom about programming from someone who is not famous? Was it a friend, a coworker, or a teacher, or a family member? For example, a technical writer friend of mine said: "You can't get the right answers unless you ask the right questions." Thanks for all the contributions! The answer I selected was (a) specifically coding-related, and (b) stated by someone who is not technically famous (though he has a popular blog and a podcast and runs StackOverflow). I.e. he's no Bill Gates or Yogi Berra.

  • ASP.NET mvcConf Videos Available

  • What is the economic rationale behind programmers who work on a open source project (free) instead of a commercial project (not free)?

    - by Kim Jong Woo
    I can't understand why some people dedicate so much hour into a completely open source project without closing it and yielding greater profit from it. I don't think profiting from your code is evil, I think it's a great motivator. Why do some people feel that commercial software and generating money from it is bad? There seems to be this black and white thinking that open source = good, commercial = bad. I hardly find this convincing, and often commercial companies which are supported by sales produce very good results. An open source software in the same niche can't compete against the corporation. Of course, sometimes this is completely the other way around where private companies produce inferior product compared to open source counterparts. So help me understand, why do programmers open source their code when there is commercial prospects for it? Shouldn't the rational programmer or human being make every effort to capitalize on their opportunity cost? Working on a open source project for months when you could've spent the same number of hours at commidity wage or some other monetary compensation?

  • Log shipping and shrinking transaction logs

    - by DavidWimbush
    I just solved a problem that had me worried for a bit. I'm log shipping from three primary servers to a single secondary server, and the transaction log disk on the secondary server was getting very full. I established that several primary databases had unused space that resulted from big, one-off updates so I could shrink their logs. But would this action be log shipped and applied to the secondary database too? I thought probably not. And, more importantly, would it break log shipping? My secondary databases are in a Standby / Read Only state so I didn't think I could shrink their logs. I RTFMd, Googled, and asked on a Q&A site (not the evil one) but was none the wiser. So I was facing a monumental round of shrink, full backup, full secondary restore and re-start log shipping (which would leave us without a disaster recovery facility for the duration). Then I thought it might be worthwhile to take a non-essential database and just make absolutely sure a log shrink on the primary wouldn't ship over and occur on the secondary as well. So I did a DBCC SHRINKFILE and kept an eye on the secondary. Bingo! Log shipping didn't blink and the log on the secondary shrank too. I just love it when something turns out even better than I dared to hope. (And I guess this highlights something I need to learn about what activities are logged.)

  • ODEE Green Field (Windows) Part 5 - Deployment and Validation

    - by AndyL-Oracle
    And here we are, almost finished with our installation of Oracle Documaker Enterprise Edition ("ODEE") in a Windows green field environment. Let's recap what we've done so far: In part 1, I went over the basic process that I intended to show with installing an ODEE on a green field server. I walked you through the basic installation of Oracle 11g database In part 2, I covered the installation of WebLogic application server. In part 3, I showed you how to install SOA Suite for WebLogic. In part 4, we did the first part of the installation of ODEE itself. What remains after all of that, is the deployment of the ODEE components onto the database and application server - so let's get to it! DATABASE First, we'll deploy the schemas to the database. The schemas are created during the ODEE installation according to the responses provided during the install process. To deploy the schemas, you'll need to login to the database server in your green field environment. Open a command line and CD into ODEE_HOME\documaker\database\oracle11g.Run SQLPLUS as SYSDBA and execute dmkr_admin.sql:  sqlplus / as sysdba @dmkr_admin.sql Execute dmkr_asline.sql, dmkr_admin_correspondence_example.sql.  If you require additional languages, run the appropriate SQL scripts (e.g. dmkr_asline_es.sql for Spanish). APPLICATION SERVER Next, we'll deploy the WebLogic domain and it's components - Documaker web services, Documaker Interactive, Documaker dashboard, and more. To deploy the components, you'll need to login to the application server in your green field environment. 1. Open Windows Explorer and navigate to ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts.2. Using a text editor such as Notepad++, modify weblogic_installation_properties and set location of MIDDLEWARE_HOME and ODEE HOME. If you have used the defaults you’ll probably need to change the E: to C: and that’s it. Save the changes.3. Continuing in the same directory, use your text editor to modify set_middleware_env.cmd and set the drive and path to MIDDLEWARE_HOME. If you have used the defaults you’ll probably need to just change E: to C: and that’s it. Save the changes.4. In the same directory, execute wls_create_domain.cmd by double-clicking it. This should run to completion. If it does not, review any errors and correct them, and rerun the script.5. In the same directory, execute wls_add_correspondence.cmd by double-clicking it - again this should run to completion. 6. Next, we'll start the AdminServer - this is the main WebLogic domain server. To start it, use Windows Explorer and navigate to MIDDLEWARE_HOME\user_projects\domains\idocumaker_domain. Double-click startWebLogic.cmd and the server startup will begin. Once you see output that indicates that the server status changed to RUNNING you may proceed.  a. Note: if you saw database connection errors, you probably didn’t make sure your database name and connection type match. You can change this manually in the WebLogic Console. Open a browser and navigate to http://localhost:7001/console (replace localhost with the name of your application server host if you aren't opening the browser on the server), and login with the the weblogic credential you provided in the ODEE installation process. b. Once you're logged in, open Services?Data Sources. Select dmkr_admin and click Connection Pool.  c. The end of the URL should match the connection type you chose. If you chose ServiceName, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<serviceName> and if you chose SID, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<SIDname> d. An example serviceName is a fully qualified DNS-style name, e.g. "idmaker.us.oracle.com". (It does not need to actually resolve in DNS). An example SID is just a name, e.g. IDMAKER. e. Save the change and repeat for the data source dmkr_asline.  f. You will also need to make the same changes in the ODEE_HOME/documaker/docfactory/config/context/.bindings file - open the file in a text editor, locate the URL lines and make the appropriate change, then save the file.  7. Back in the ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts directory, execute create_users_groups.cmd. 8. In the same directory, execute create_users_groups_correspondence_example.cmd. 9. Open a browser and navigate to http://localhost:7001/jpsquery. Replace localhost with the name of your application server host if you aren't running the browser on the application server. If you changed the default port for the AdminServer from 7001, use the port you changed it to. You should see output like this: 10. Start the WebLogic managed servers by opening a command prompt and navigating to MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/. When you start the servers listed below, you will be prompted to enter the WebLogic credentials to start the server. You can prevent this by providing the credential in the startManagedwebLogic.cmd file for the WLS_USER and WLS_PASS values. Note that the credential will be stored in cleartext. To start the server, type in the command shown. a. Start the JMS Server: ./startManagedWebLogic.cmd jms_server b. Start Dashboard/Documaker Administrator: ./startManagedWebLogic.cmd dmkr_server c. Start Documaker Interactive for Correspondence: ./startManagedWebLogic.cmd idm_server SOA Composites  If you're planning on testing out the approval process components of BPEL that can be used with Documaker Interactive, then use the following steps to deploy the SOA composites. If you're not going to use BPEL, you can skip to the next section.1. Stop the servers listed in the previous section (Step 10) in the reverse order that they were started.2. Run the Domain configuration command: navigate to and execute MIDDLEWARE_HOME/wlserver_10.3/common/bin/config.cmd.3. Select Extend and click next. 4. Select the iDocumaker Domain and click Next. 5. Select the Oracle SOA Suite – 11.1.1.0 (this may automatically select other components which is OK). Click Next. 6. View the Configure JDBC resources screen. You should not make any changes. Click Next. 7. Check both connections and click Test Connections. After successful test, click Next. If the tests fail, something is broken. Go back to configure JDBC resources and check your service name/SID. 8. Check all schemas. Set a password (will be the same for all schemas). Enter the database information (service name, host name, port). Click Next. 9. Connections should test successfully. If not, go back and fix any errors. Click Next. 10. Click Next to pass through Optional Configuration. 11. Click Extend. 12. Click Done. 13. Open a terminal window and navigate to/execute: ODEE_HOME/documaker/j2ee/weblogic/oracle11g/bpel/antbuild.cmd14. Start the WebLogic Servers – AdminServer, jms_server, dmkr_server, idm_server. If you forgot how to do this, see the previous section Step 10. Note: if you previously changed the startManagedWebLogic.cmd script for WLS_USER and WLS_PASS you will need to make those changes again. 15. Start the WebLogic server soa_server1: MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/startManagedWebLogic.cmd soa_server116. Open a browser to http://localhost:7001/console and login. 17. Navigate to Services?Data Sources and select DMKR_ASLINE. 18. Click the Targets tab. Check soa_server1, then click Save. Repeat for the DMKR_ADMIN data source. 19. Open a command prompt and navigate to ODEE_HOME/j2ee/weblogic/oracle11g/scripts, then execute deploy_soa.cmd. That's it! (As if that wasn't enough?) DOCUMAKER Deploy the sample MRL resources by navigating to/executing ODEE_HOME/documaker/mstrres/dmres/deploysamplemrl.bat. You should see approximately 500 resources deployed into the database. Start the Factory Services. Start?Run?services.msc. Locate the service named "ODDF xxxx" and right-click, select Start. Note that each Assembly Line has a separate Factory setup, including its own Factory service and Docupresentment service. The services are named for the assembly line and the machine on which they are installed (because you could have multiple machines servicing a single assembly line, so this allows for easy scripting to control all the services if you choose to do so. Repeat for the Docupresentment service. Note that each Assembly Line has a separate Docupresentment. Using Windows Explorer, navigate to ODEE_HOME/documaker/mstrres/dmres/input and select one of the XML files, and copy it into ODEE_HOME/documaker/hotdirectory. Note: if you chose a different hot directory during installation, copy the file there instead. Momentarily you should see the XML file disappear! Open browser and navigate to http://localhost:10001/DocumakerDashboard (previous versions 12.0-12.2 use http://localhost:10001/dashboard) and verify that job processed successfully. Note that some transactions may fail if you do not have a properly configured email server, and this is ok. You can set up a simple SMTP server (just search the internet for "SMTP developer" and you'll get several to choose from.  So... that's it? Where are we at this point? You now have a completely functional ODEE installation, from soup to nuts as they say. You can further expand your installation by doing some of the following activities: clustering WebLogic services configuring WebLogic for redundancy configuring Oracle 11g for RAC adding additional Factory servers for redundancy/processing capacity setting up a real MRL (instead of the sample resources) testing Documaker Web Services for job submission and more!  I certainly hope you've enjoyed this and find it useful. If you find yourself running into trouble, visit the Oracle Community for Documaker - there is plenty of activity there and you can ask questions. For more concentrated assistance, you can engage an Oracle consultant who is a subject matter expert to assist you. Feel free to email me [andy (dot) little (at) oracle (dot) com] and I can connect you with the appropriate resource to get started. Best of luck! -Andy

  • What causes bad performance in consumer apps?

    - by Crashworks
    My Comcast DVR takes at least three seconds to respond to every remote control keypress, making the simple task of watching television into a frustrating button-mashing experience. My iPhone takes at least fifteen seconds to display text messages and crashes ¼ of the times I try to bring up the iPad app; simply receiving and reading an email often takes well over a minute. Even the navcom in my car has mushy and unresponsive controls, often swallowing successive inputs if I make them less than a few seconds apart. These are all fixed-hardware end-consumer appliances for which usability should be paramount, and yet they all fail at basic responsiveness and latency. Their software is just too slow. What's behind this? Is it a technical problem, or a social one? Who or what is responsible? Is it because these were all written in managed, garbage-collected languages rather than native code? Is it the individual programmers who wrote the software for these devices? In all of these cases the app developers knew exactly what hardware platform they were targeting and what its capabilities were; did they not take it into account? Is it the guy who goes around repeating "optimization is the root of all evil," did he lead them astray? Was it a mentality of "oh it's just an additional 100ms" each time until all those milliseconds add up to minutes? Is it my fault, for having bought these products in the first place? This is a subjective question, with no single answer, but I'm often frustrated to see so many answers here saying "oh, don't worry about code speed, performance doesn't matter" when clearly at some point it does matter for the end-user who gets stuck with a slow, unresponsive, awful experience. So, at what point did things go wrong for these products? What can we as programmers do to avoid inflicting this pain on our own customers?
