WebLogic Admin Tricks & Tips

Configure a WebLogic Server Background Service server running in the background which is very much required in Production and Test Environments where your operating platform is Windows NT based. Whenever the Windows server is rebooted the WebLogic Admin server or Managed servers running on it are going to started automatically, when they are configured with windows ‘services’. Use WebLogic existing Domain or Create a Domain for testing  Create a installation Script per WebLogic server such as AdminServer or Managed Server Create a .cmd let us workout per AdminServer  with the following  Open notepad or any editor to write the following Windows batch Script echo off SETLOCAL set DOMAIN_NAME=demoDomain set USERDOMAIN_HOME=F:\irfan\demoDomain set SERVER_NAME=AdminServer call "F:\Oracle\wlserver\server\bin\installSvc.cmd" ENDLOCAL Write the above code and SAVE it with ‘AdminServerSrv.cmd’ in your domain\bin open a n...

jps - Java process list : Java Utilitycommand  I was looking for diagnostic ways with freely available tools from JDK then I found the great valuable command tool 'jps'. The jps command can be used with three options(l, v, m). it can work for any Java - JEE Servers such as WebLogic, WebSphere, JBoss, Tomcat. In other words, any app server that uses the latest JDK 5+ version (version 6, 7, 8 also supports). Let me walk-through those interesting options in Win and *nix platforms. Before you execute this command tool, make sure that JAVA_HOME\bin is in the PATH setting. Java Command tool : jps options jps Option : jps -l this -l option will give the full Java package name that invoked the Java process. C:\Users\pavanbsd>jps -l 9116 sun.tools.jps.Jps 8812 weblogic.Server Filtering the weblogic instance with find command on jps will give you the desired outcome. C:\Users\pavanbsd>jps -l |find "weblogic" 8812 weblogic.Server jps -v this -v option is m...

Problem: Closing startWebLogic.cmd execution window - SHUTDOWN server We were working on Oracle Fusion Middleware environment, where the WLS_FORMS managed server was down. We need to bring it up by starting the server immediately, because it is live we have tried to start with nodemanager. But, it is failed! due to the stdout log rotation failure unable to start the managed server. The servers running on the same Windows machine are well and RUNNING state. Production environments we cannot keep a server DOWN for longer time. So first we tried with immediate temporary solution is to start the managed server from the domain home we need to keep a CMD window open. If someone logged in and closed the window the server will be down again! In UNIX we have nohup and &(ampersand) to run in the background. Now we need similar solution in Windows platform. After working in Unix platform for many years, felt Windows is hard to us!!! There is always a way for this problem. Solution we iden...

To monitor and send the traps for issues we must have mail service enabled. In Linux how to check mail service up? We have tried to test the sendmail command from the Linux machine. with the following command: echo "This is the body."| mailx -s "mailx Test1" bhavanishekhar@gmail.com echo "test" | mailx -s "test_sub" bhavanishekhar@gmail.com When I tested with the above test message got the error saying as follows: postdrop: warning: unable to look up public/pickup: No such file or directory. There is no mail service is running you validate the same with the following: We have several options checking the processes list for the pattern 'mail'. $ ps aux | grep mail |grep -v grep $ or use other option is usually the mail service on Unix machine runs on port 25, so grep it fro...
