Oracle recommends creating a separate MDS schema to store custom Webcenter application metadata. Using existing MDS schemas may corrupt seeded repositories.

1. Run rcu from RCU_HOME/bin folder. Skip the first screen.
2. Specify Database connection parameters in the next step.
3. From “Select Components” screen, specify “ORAFMWSCHOOL” for “Create a new Prefix”. Select Oracle AS Repository Components –> AS Common Schemas –> Metadata Services. Click Next.
4. Enter schema password and confirm the same.
5. Click Next and then Finish.

This creates ORAFMWSCHOOL_MDS schema in the database.

Login to Enterprise Manager console using http://localhost:7001/em

Click on “Metadata Repositories” link from left sidebar.

Click on “mds-soa” to bring up SOA MDS repository detail screen. From “Metadata Repository” menu under mds-soa, select Administration –> Register/Deregister.

From Database Repositories section, click on “Register…”. Enter database details and click on Query.

Select ORAFMWSCHOOL_MDS from the list of displayed Metadata Repositories. Enter a Repository Name and Schema password we created in Step 2.

This completes registration of repository with Oracle Weblogic server domain.
