We need to look at the logs:
Open an SR with oracle support
I experienced a similar issue. By any chance do you have BI Publisher installed in your environment?
See if this notes helps resolve your issue: EM 12c: Add OMS fails while Starting the OMS with error "CLONE-20901 Unable to restore permission of a few files" [ID 1503606.1]
Had to apply patch 13349651 for WLS , retried the procedure and then it was successful.
I have SR oponened with Oracle and I am frustrated since all the solutions provided have not worked yet.
My SR is SR 3-7364013631.
no we do not have BI Publisher installed in our environment.
Let me look at the Sr details- SR 3-7364013631 and get back to you, i will also talk with the support engineer
We see following error in logs-
2013-06-10 16:57:42,481 [EMMetadataServiceDriver:Thread-14] ERROR swlib.txfr - There was an exception while uploading file to fileset with guid=DED4DE838BED4F47E0432A43600A2D55 for path=ouiOnlyPrereqs.pl. Setting the file entry status to ERROR.
oracle.sysman.emSDK.swlib.storage.StorageException: *The filesystem for the library is not correctly configured, or the directory /omsshare/3 could not be accessed.*
Suspecting software library some files are all 0 bytes - this was caused due to a problem with the NFS mount-point where software library is configured. This is a know issue Bug16374229 and fixed in next EM release. For now, support will be updating you how to move forward, also refer-1531166.1
I moved all the files from a shared Software location to a different directory. I re-imported Metadata from Console, and indeed the corrupted files that earlier showed to have 0 bytes now showed with some bytes this time. I cleaned up the failed installation and re-tried addiing OMS procedure from the beggining, and completed successfully. Doc ID 1531166.1 resolved the issue.
Thanks for updating us
