While Installing schemas using RCU utility for the latest SOA 12.2.1 release, following error occurred irrespective of Database version (10g XE, 11g XE, 11gR2, 12c).
After Ignoring the error, rest of RCU installation went through fine. On logging in with MDS schema user account (<prefix>_MDS), JDev shows following error
These kind of errors occur occasionally in 11g and re-compilation in JDev would resolve the issue. However, re-compiling gave “Malformed or Corrupted wrapped unit” error.
I suspected <home>\oracle_common\common\sql\mds\sql\MDSINCB.plb is corrupted and tried Online Unwrap service. The online service was able to unwrap the package without any issue.
Re-running the MDSINCB.plb script from SQL worksheet fixed the issue.
