Weblogic Domain re-configuration

In this blog we will see domain re-configuration which will be done as part of Weblogic migration from lower version to higher version [ Ex Weblogic 12 to Weblogic 14 or Weblogic 10 to Weblogic 12 or weblogic 10 to 14 version]

/sw/bea14 – path contains weblogic 14.1.1
/sw/java8_64 — path contains Java 1.8 281

/aps for Domains and /sw mount points available software installations in our case

We will bave /sw/bea12 installed and have a domain /aps/tst/tstDomain

Domain Reconfiguration
1) Backup Entire tstDomain before reconfiguring the domain

Note: wlst.sh should be executed from the new version
2) execute /sw/bea14/oracle_common/common/bin/wlst.sh
3) in offline WLST execute in sequence
a) readDomainForUpgrade(‘/aps/tst/tstDomain’)
b) updateDomain()
c) closeDomain()
d) exit()
4) Update setDomainEnv.sh with the new location of commEnv.sh at
${WL_HOME}/../oracle_common/common/bin/commEnv.sh
5) Rename WLS_DIAGNOSTICSxxxxxx.DAT for each instance in {instance folder}/data/store/diagnostics
6) Start the services and verify .

Now verify the Admin console and logs it will reflect latest version of Weblogic .

Error’s that might happen during domain re-configuration

CAUSE

The cause behind the issue is with corrupted config.xml file for the upgrading domain.

SOLUTION

Use the following to resolve:

1. Restore correct config.xml from backup to $DOMAIN_HOME/config/config.xml file for upgrading WebLogic domain.
2. To re-configure / Upgrade a WebLogic Domain Using WebLogic Scripting Tool (WLST)

a. Navigate to <12.2.1.4_ORACLE_HOME>/oracle_common/common/bin
    Invoke WLST using ./wlst.sh or java weblogic.WLST

b. Open the domain for upgrade.

    wls:/offline> readDomainForUpgrade()
    Example:
    readDomainForUpgrade(‘/full-path-to-the WLS-domain-to-be-upgraded’)

    # Save the updated domain.
     wls:/offline/my_domain> updateDomain()

    # Close the domain.
     wls:/offline/my_domain> closeDomain()
 

Try above changes that are provide as part for Oracle Weblogic Documentation .
