You can optimize repository performance on IBM DB2 EEE databases when you store a PowerCenter repository in a single-node tablespace. When setting up an IBM DB2 EEE database, the database administrator can define the database on a single node.
When the tablespace contains one node, the PowerCenter Client and Integration Service access the repository faster than if the repository tables exist on different database nodes.
If you do not specify the tablespace name when you create, copy, or restore a repository, the DB2 system specifies the default tablespace for each repository table. The DB2 system may or may not specify a single-node tablespace.
