Real time commands for WebLogic and web sphere in Linux environment. 






This blog contains all the basic information to work with the LINUX 

and WebLogic details. Every command is used in the realtime. 

You can refer to this blog to get a glance at all the commands.





CPU information -- This is generally taken care of by system administrator but it is 

better to have an idea on those and recheck them before starting the servers.


                #cat /proc/cpuinfo
                #cat /proc/cpuinfo | grep cores






To change the permission for any folder in the Linux machine.

                        #chown –R user:group foldername







This item to be resolved between the servers. The entries to be checked before starting the 

servers.

                        more /etc/hosts







DNS entries are available in this file. These are to be checked before the process. 

Verify with the system team to avoid issues.


                            more /etc/resolv.conf







The database scan names to be checked. Check the connectivity from the application servers to 

DB servers. If not check the /etc/hosts entries and make surer it is resolved.  





                                nslookup <scanName>









To check the port availability and to confirm the ports are enabled from the security team you 

should telnet the IP and Port as below.


                                    telnet <IP> <port>


















This is an advanced feature to be checked and better to set these values of setting 

PID and thread ID


                         more /proc/sys/kernel/pid_max        (recommendation 65356)
  
                        more /proc/sys/kernel/threads-max   







CRONJOB

To see the list of cron jobs running in the background

                        crontab -l







To set the cronjobs in the servers and execute on restart of the server

                          crontab -e






List all the java process that is running which include the server information and also the 

applications that are running in the server background  


               ps -ef | grep java
  






To get information about all the open ports in the server.


                            sudo lsof -i -P -n | grep LISTEN

                            netstat -tulpn | grep LISTEN
  
    




To get the routing table information from the server


                            netstat -rn ------------- kernel routing table(gateway check)








Get to know the WebLogic version that is running in the server

Go to directory which contains weblogic.jar ($WL_HOME/server/lib)

            kar@sys#>java -cp weblogic.jar weblogic.version

                    WebLogic Server 10.3.5.0  Fri Apr 1 20:20:06 PDT 2011 1398638




Note:
                Use 'weblogic.version -verbose' to get subsystem information
                Use 'weblogic.utils.Versions' to get version information for all modules








Basic commands to get start WebLogic admin server and managed servers.




                ./startWeblogic.sh

                ./startManagedWebLogic.sh Domain_machine1 http://192.199.77.11:7000

                ./startManagedWebLogic.sh saudi_ins1_1 http://192.199.77.11:7000








Creation of security folder and provide user info which will be encrypted and used during the start of 

the managed servers. boot.properties folder setup. Each and every managed server to be set with 

this file. 



cd /u01/app/oracle/Middleware/user_projects/domains/DOMAINNAME/servers/AdminServer 



mkdir security



cd security



vi boot.properties



username=system



password=********



Note: The same to be done with all the managed servers.
















Replace the word in the file that is in Linux machine



vi filename



press esc



%s/prdfshapp1/prdfshapp2/g



:wq!













PACK AND UNPACK commands for migration.

















pack -domain=/opt/bea/bea10.3.6/user_projects/domains/DomainName 

-template=/opt/bea/bea10.3/user_templates/mydomain.jar -template_name="My WebLogic Domain"















unpack -template=/opt/bea/bea10.3.6/user_templates/mydomain.jar 

-domain=/opt/bea/bea10.3/user_projects/domains/NameDomain
















System information related commands.



Get all the details of the host server



more /etc/redhat-release



Get the hostname



uname -a

















SSH between the server. We login to the server within the same subnet and then we 

SSH to the other server using below command.















ssh usename@192.115.16.12






It prompts for a password.


















To copy a file from one server to another. ( SSH with port 22 should be enabled.)



scp fileName.txt username@192.168.11.12:/destination/diectory



If it is a folder



scp -r folderName username@192.168.11.12:/destination/diectory



Setting class path:

change directory to WL_HOME\server\bin\setWLSEnv.sh and set required class paths.

WEBSPHERE INTERVIEW QUESTIONS COVERING ALL TOPICS

Interview questions and also find the realtime usage commands link at the end of the blog. Which will be helpful during the interview. In a Web-based architecture, if you try to hit the URL, it shows an error like page cannot be displayed, How to troubleshoot this issue? Ans: The Flow of Request happens from Load Balancer >> Webserver >> Appserver >> DBso the investigation for such issues should also follow the same routes .. ( well thats how i follow ) Try to check if the url is responding from your end. (This will eliminate if its specific to a user or its error for every one) Check the Webserver if its running or not, If it’s not running start it Check if the application server and application is running.. if not start it Try to access the Application directly from the Appserver .. ie using the http transport port. ie wc_defalut .. ( this will identify if the error is due to App server or is with the Webserver/plugin) check for the e...
