Weblogic Not Starting with Error: JPS-06514: Opening of file based keystore failed

Recently, I encountered an issue where the Weblogic Admin server did not start due to an error  JPS-06514: Opening of file based keystore failed

Error Message:

Solution:

1.Delete all pki files under /tmp and rename keystores.xml(domain/config) and cwallet.sso(domain/config/fmwconfig/bootstrap).

2. Delete the tmp directory under the $DOMAIN_HOME/servers/AdminServer

3.Start the weblogic server

Happy Learning!
