MDS-01330: unable to load MDS configuration document

After successful installation of SOA(11g) 11.1.1.5 on Oracle XE when I started the managed server I faced following exception which makes me worried.... and kept on thinking for few minutes ....do I need to reinstall everything but thanks God I got a solution.
I hope this helps to all who faced such an issue.

Exception

oracle.mds.lcm.exception.MDSLCMException: MDS-01330: unable to load MDS configuration document
MDS-01329: unable to load element "persistence-config"
MDS-01370: MetadataStore configuration for metadata-store-usage "soa-infra-store" is invalid.
ORA-04063: package body "DEV_MDS.MDS_INTERNAL_SHREDDED" has errors
ORA-06508: PL/SQL: could not find program unit being called: "DEV_MDS.MDS_INTERNAL_SHREDDED"
ORA-06512: at line 1.....

Solution

1. First of all drop SOA Suite schemas and associated tablespaces using RUC.
2. Then go to command line (cmd) and set environment variable RCU_JDBC_TRIM_BLOCKS=TRUE
3. Run RCU again to re-create the SOA Suite schemas and tablespace

Now restart server and this time there will be no error associated with "MDS-01330: unable to load MDS configuration document"
