This segment documents information that is provided to help you diagnose OAM problems.

OAM allows multiple DB2 databases to be used for object storage. Each object storage database has an object directory table space, a 4 KB Object Storage Table space, and a 32 KB Object Storage Table space. Within each table space is one table (an object directory table, a 4 KB Object Storage Table, and a 32 KB Object Storage Table, respectively). Each database has three indexes into the object directory table and one index into each of the object storage tables. The high-level qualifier on the object storage database must match the high-level qualifier on the object storage definition in the SCDS that was created using ISMF and the high-level qualifier and package name in PBIND.

Object storage administration uses one additional database. The object storage administration database name is OAMADMIN. This database contains a management class table space, a storage class table space, and a collection name table space. Within each table space is one table (a management class table, a storage class table, and a collection name table, respectively). The management class table and the storage class table each have one index, and the collection name table has three indexes.

Each OAM DB2 object storage database has its own separately defined set of VSAM data sets. There is one VSAM data set for each table space, and one VSAM data set for each index within the database.
