I recommend performing the following to help clean up your database in the following order:

1. Delete obsolete test runs from within Performance Center

2. Delete obsolete projects from within Performance Center

**** Before executing steps 3 through 5 below, wait 8 days for the ALM-PC Database to synchronize ****

1. Verify Domains and Projects

? You run the verification process to check the correctness of your data base user schema and data
? Review the ALM 12.01 Administrator Guide Verify Domains and Projects starting on page 115.

2. Realign the Repository

? The realigning process verifies the integrity of the relationship between the logical and physical database tables.
? The realigning process performs the following actions:

§ If a file is indexed in the database but is not located in the file system, the index of the file is removed from the database.

§ If a file is stored in the file system but is not indexed in the database, the file is deleted from the file system.

? Review the ALM 12.01 Administrator Guide Realigning Repositories starting on page 86. This guide has been
uploaded to this case for reference.

5. Ask the DBA to reprofile / re-sequence / clean up the Oracle database
