• Install PT8.53 with Linux question: setup.sh can't recreate WebLogic Server PIA

  People,

  Hello. I install PeopleTools 8.53 with the server database Oracle 11 GR 1 material and OS Oracle Linux 5. Data Mover Bootstrap and application designer can connect to the instance of database successfully. About PIA, Oracle Database Server and Application Server Tuxedo11gR1 runs correctly. But when to start WebLogic Server in the opt/PT8.53/webserv/PT853/bin directory, I get an error message like below:

  [user@userlinux bin] $./startPIA.sh

  Its output:

  Try to start WebLogic Server PIA
  No activity will be connected to this window.
  Activity on the server will be connected to /opt/PT8.53/webserv/PT853/servers/PIA/logs/PIA_*
  PID for WebLogic Server PIA is: 5462

  In the direcctory /opt/PT8.53/webserv/PT853/servers/PIA/logs, I run the following command:

  [user@mylinux log] $ vi PIA_stdout.log

  Its release containing the primary error message:

  Another process is using port 80: exception java.net.BindException: Permission denied.

  The 127.0.0.1 address may be incorrect or another process is using port 443: exception java.net.BindException: Permission denied.

  Because I changed the MAX_FILE_DESCRIPTORS from 4096 to 1024 in the file 'setenv.sh', I can't start PIA on the ports lower then 1024 on Linux with a non-root users. I need to recreate PIAS and assign ports like 8000 and 4443. I have remove the PIA installed folder opt/PT8.53/webserv.  I recreate PIA in the directory /opt/PT8.53/setup/PsMpPIAInstall/ as below:

  [user@userlinux PsMpPIAInstall] $./setup.sh

  Its output:

  Select the web server root directory/home/user/oracle/Middleware

  Web server detected version: no choices available

  Error: The web server root directory entered is an invalid or incorrect version.

  Please try again. The version of the required web server is "Weblogic 10.3.

  
  My installed WebLogic directories are /home/user/oracle/Middleware/wlserver_10.3 and /home/user/oracle/Middleware/coherence_3.7 and I run WebLogic Console successfully with http://mylinux.mydomain:7001 / console. I think that the directory/home/user/oracle/Middleware is correct, but it says "no choices available".

  The first time, setup.sh runs correctly. In the second, setup.sh Gets the error above after deleting its previous /opt/PT8.53/webserv file installed.

  My question is:

  Can any folk solve the above problem to make run them "setup.sh" to recreate WebLogic PIA again assign ports greater than 1024?

  
  Thank you.

  See your original thread.

• Install PT8.53 Linux question: startPIA.sh cannot run the WebLogic Server

  
  People,

  Hello. I install PeopleTools 8.53 with the server database Oracle 11 GR 1 material and OS Oracle Linux 5. Data Mover Bootstrap and application designer can connect to the instance of database successfully. About PIA, Oracle Database Server and Application Server Tuxedo11gR1 runs correctly.

  PID for WebLogic Server PIA is: 5462

  According to the site Internet of Nicolas http://gasparotto.blogspot.com/2010/02/web-server-weblogic-11gR1.html, I did 2 things like below:

  
  First of all, in the setenv.sh file, I changed MAX_FILE_DESCRIPTORS to 4096 to 1024.

  
  Secondly, I added the last 4 lines in the /etc/security/limits.conf file as below:

  # - nice - max great priority has led to increase of

  WebLogic - nproc 65536
  WebLogic - unlimited core
  WebLogic - memlock 50000000

  # End of file

  
  I have restart startPIA.sh and get the same error message:

  Try to start WebLogic Server PIA
  No activity will be connected to this window.
  Activity on the server will be connected to /opt/PT8.53/webserv/PT853/servers/PIA/logs/PIA_*
  PID for WebLogic Server PIA is: 5462

  
  My question is: any folk cannot resolve the error above to start the WebLogic for PIA Server?

  Thank you.

  As Nicolas says that you cannot start PIA on ports below 1024 on Linux with a non-root users.

  Recreate your PIA assembly and affect others like 8000 and 4443.

• Question about steps for Weblogic Server 8.1 to 10.3 Upgrade

  Hello!
  
  We have upgraded our server Weblogic 8.1 to 10.3. Could someone advise me:
  
  1. how to upgrade the Weblogic 8.1 to 10.3 Server? The Weblogic Server 10.3 can coexist in a single physical server with Weblogic Server 8.1?
  
  2. when the software upgrade can be downloaded?
  
  3. we have a web service running under Weblogic Workshop, Weblogic Server is started through the workshop. This web service can be run in Weblogic Server 10.3?
  
  4. are there predictable questions/problems that will happen?
  
  Please kindly help me. Thank you very much.
  
  Best regards
  May

  Download location: http://www.oracle.com/technology/software/products/ias/htdocs/wls_main.html
  You can upgrade the domain after you install wls 10.3 using quick start.
  When we migrated, we went from windows to linux. We have installed, created the field, servers managed, configured, etc from scratch. We have no problems "show-stopper".

• ADF Logger | How to configure Weblogic Server

  Hi all

  I use JDev 12 c and weblogic server 10.3.

  I have configured the recorder in my local, using logging.xml and print newspapers in specific file. which works fine locally.

  Now, I have to implement the same stand-alone weblogic Server (production).

  I understand that by the link below is, I'll have logging.xml in the server as well and I have to configure the same setting in weblogic server.

  JDeveloper frequently asked Questions: FAQ #33 - how to set up the recording of WLS, PT. 3 Diagnostics ADF

  But I don't see any of the weblogic server logging.xml file.

  Please suggest how can I implement the same in weblogic server.

• Typical interview question

  Hi all

  I have a typical interview question, I tried the solution, but did not find.

  1 Int that: scheduled backup RMAN is running normal and run DBA "shutdown" command for an interview without knowing about backup, will, RMAN work ends or gets killed?

  My answer: because it's a normal shutdown, it should wait until existing complete process and restrict new connections

  2 Int that: If there are two channels allocated for the backup of the db and a channel separate for archivelog, the rman job status is db backup is complete and has been asked to stop, he will start archivelog backup channel?

  Run {allocate channel d1 type disk;}

  allocate channel d2 type disk;

  backup database;

  output channel d1;

  output channel d2;

  allocate channel d3 type disk;

  ARCHIVELOG backup all;

  output channel d3;

  }

  I'm confused here, I tried to find the answer on the forum, as well as google, but did not find. Unfortunately I do not have a test machine to try this scenario myself. Therefore, ask your valuable contributions.

  Also let me know if my assumption is correct and to expect all connections stop normal and transactional (only users or RMAN, expdp, etc as well), I check this link, but it is not categorize connections http://docs.oracle.com/cd/E11882_01/server.112/e16604/ch_twelve042.htm

  Thank you very much in advance!

  AbbasDBA

  As the session already exists, rman allocates channels at the initial stage only, it reuses just channel placement phase by phase. So in this case it will not stop, it will continue with archives too

• Administration server and the servers managed (WebLogic Server).

  Hello

  What are Server Administration and managed servers , I saw these words as I read the installation guide for WebLogic server,

  but I don't know what they are?

  
  

  I saw them while I was reading on the Node manager that allows me to start the above mentioned.

  
  

  -J' installs the WebLogic to develop applications with oracle reports and forms services.

  
  

  1 - do I need a node Manager, Administration Server or managed servers?

  
  

  2. is the Manager nodes, Server Administration or servers managed as EnterPrise data control manager ?

  
  

  Thank you very much

  Answers to most of your questions WLS lie in WLS documentation:

  http://docs.Oracle.com/CD/E23943_01/Web.1111/e13752/TOC.htm

  However, a simple answer to your questions could be summed up as follows.

  If you are familiar with older versions of application server version 10, which include OC4J as its Java container, as a managed WLS server is basically the same thing.  In the context of WLS, a managed server is responsible for hosting java applications on the server side.  For example, Oracle Forms Servlet.  The WLS management server is actually a java application deployed on a managed server.  So, really, the "Admin" server is a kind of "Managed Server".  In a typical installation of forms/States, you will find that at least three 3 managed servers are created automatically for you:

  • Server Admin
  • WLS_FORMS
  • WLS_REPORTS

  Node Manager is a separate process that is used to allow the two directors of the WLS environment such as command line allowing the administrator of the server to communicate with other servers managed, local or remote.

  http://docs.Oracle.com/CD/E25178_01/Web.1111/e13740/overview.htm

  Then, for simply "run" apply (forms, for example), all you need is the managed server that hosts the forms Servlet.  However, if you want to change the configuration via a web interface, you must also run the administration server (and Node Manager).

  All these components are much more complex than what I've described here.  I would recommend to consider the documentation if you are interested in learning about them.  That said, the best way to really learn about them likely will be to install the product and start using it.

• First construction of DEFAULT DOMAIN for "Integrated Weblogic Server" in jDeveloper 12 c gave ERROR: wlst &gt; error occurred during initialization of the virtual machine;

• Verification of the users belonging to the Group spasfic weblogic server

  I built a simple service application web with jdeveloper 11.1.1.7 strategy (Wssp1.2 - 2007-Https-UsernameToken - Plain.xml) and deploy the weblogic 10.3. Everything works very well in both the client side and server.

  The client side is unable to call any method without specifying the username and password properties. The server automatically checks the user in users values define in weblogic server in the following path (summary of the areas of security > myrealm > users and groups). Hereby, the customer can access the system if he takes one of the users in this group even with the default user weblogic/weblogic.

  Question: How to limit the name to username/password check with specific usergroup?. That is, if the client mentions the name of user and password outside of the Group (even if the values are correct) the server rejects the request

  Problem, solved by (user name: Roque)

  in this link: java - verification of users within the spasfic group of weblogic server for the web service application - Stack Overflow

  Here is his answer for your reference:

  If you use the 'default' weblogic for users authentication method, you can follow these steps to set up an access group policy:

  • Connect to the weblogic administration console
  • Click on the links of deployments
  • Select your webservice
  • Click the Security tab
  • Click the sub-tab political
  • Choose your authorization provider in the menu drop-down (looks like by default)
  • Choose Add Conditions-> Group-> Type in the name of the Group
  • Finishing

  Now that the group you added should be able to invoke the web service. All other users should see something like:

  javax.xml.ws.soap.SOAPFaultException: Access denied to operation myWebService

• Application of the ADF does not work after deployment to weblogic Server (quartz Scheduler is used)

  I created a Web merger Application using Jdeveloper 11.1.1.7. I use quartz Scheduler that will run the application automatically according to a predefined interval.

  The application works perfectly in Jdeveloper and no problem at all. The problem is when the application is deployed on weblogic server.

  Simply, the Scheduler is not rely on weblogic server and the application is not running.

  Any idea what can cause this problem? any idea would be appreciated, thanks in advance

  You should check the server logs in order to understand what happens when you call the Scheduler. There, you will come to know if there is an error message.

  Actually, it's the only way that outside help me to solved the problem. It has nothing to do with the quartz Scheduler , it was question of jdbc where the connection to the application module was not set correctly. Problem solved with application module configuration changed to use instead of the URL JDBC data source

• With regard to Apex configuring the listener using Weblogic Server.

  Dear all,

  Well, I have configured my interlocutor Apex in my Web server and everything worked fine. But my requirement is like I need for my URL should like this format http://hostname/ReportServer: port/dev/apex but by default, as we know it comes as http://hostname/ReportServer: port/apex/dev (as I gave the url mapping path/dev). So I tried by changing its name as DEV while deploying the APEX. File. WAR and I gave the root context than dev. Now question is even if configuration directory given i like "dev" but still its showing as 'Listener not configured'. Pls someone help me in this. Help is very appreciated.

  My configuration file is "/home/oracle/apex_listener.2.0.3.221.10.13/dev"

  But even once apex named subdirectory is created inside this dev automatically.

  In regards to this link, I had an idea but its incomplete since his unanswered, so I'm bit confused too.

  https://community.Oracle.com/thread/2134379

  I thought to change httpd.conf file and give redirect URL but I'm not sure that can we redirect modulewise as separate 'apex' named subdirectory is created in "dev" then configuration gets effect as how it will work and mod_rewrite option I have seen but can't understand as including one to pick up. Please suggest...

  My Version of the apex is 4.2.3

  Apex listener Version is 2.0.3

  As appropriate, any other information please ask me.

  Kind regards

  Nitesh Perron.

  Dear all,

  Finally I found the solution for this.  I put here so that it can be useful to others who may face difficulties like me,.

  Floorconstruction:

  After changing the root of context just start your deployed war file and test it.

  While reaching the URL,

  Web page showing "listener apex not configured" and it will show you the location of the configuration on the Web page itself.

  Then you simply copy all directories and subdirectories (that were created when you set up your database using the file. War) at the location that shown on the Web page.

  As we change the root context so a named directory context root allows to create inside the path configured, if web is unable to find configurations because it happens inside the different directory so just copy everything and try. It worked for me very smoothly.

  My position was ' /home/oracle/apex_listener.2.0.3.221.10.13/apex"(before changing the context root in weblogic server).

  Then after the change and start the deployment once again, it became ' /home/oracle/apex_listener.2.0.3.221.10.13/dev', since I gave my root of context like "dev."

  So here I just copied directory "apex" on the dev directory and it worked fine and I got my desired URL as http://localhost:port/dev/apexhttp://localhostport .

  And all applications also works very well.

  Still, I felt its not correct way to view security, but this is the solution I found and I will try apache to redirect my URL.

  Thank you

  Kind regards

  Nitesh Perron.
