EBS 12.1.3 on OUL6x64 database 126.96.36.199
We want to install patch 9452181(Opatch) to upgrade JavaMail API to version 1.4.x (EBS R12 12.1.3 database 11gR2 188.8.131.52)
but got the error message
Conflicting patches: 8999551,
Patch(es) 8999551, conflict with the patch currently being installed (9452181).
If you continue, patch(es) 8999551, will be rolled back and the
new patch (9452181) will be installed
Does anyone has this issue before
Oracle support replied, it is fine to rollback patch 8999551 and apply patch 9452181and use the new JavaMail 1.4.x
-- also 1.4 Javamail Api is what comes with the later 12.2 release.
