Opatch upgrade, error with central inventory :

OSB > Clean pending sessions :
When there is a genuine session duplicate case, you will find more than one system directory within this directory: $OSB_DOMAIN/osb/config/sessions
– Delete the secondary system directory and try for session activation.
– If that does not work, delete everything under
$OSB_DOMAIN/osb/config/sessions
– Restart your Admin server with the deletion of cache, tmp, data & stage directories
– Make sure, when you are changing anything in OSB console, no other user is trying to change from console at the same time.
No user should know your login credentials. Parallel login with same credentials, trying to activate session at the same time can create such issue.
– Make sure, nobody has clicked on Lock & Edit button in Weblogic server to change any parameter.
– Sometimes, if all of the above steps did not help, go for rolling restart of the entire domain. Delete cache, tmp, data & stage for all managed servers along with admin server including tmp from domain directory itself.
