OAM configuration database

The OAM configuration database (CBROAM) contains configuration information related to the target destinations for objects including tape volumes, optical libraries, drives, slots, and volumes. CBROAM also identifies objects to be ultimately deleted by OAM from optical volumes and the file system. It is a DB2 database and consists of the following tables:

Library: Contains one row for each optical library. The DB2 name of this table is OLIBRARY. There is a unique index on the library name.
Drive: Contains one row for each optical drive, whether operator-accessible or library-resident. The DB2 name of this table is DRIVE. There are two indexes defined on the table; one is unique and one is not.
Slot: Contains one row for each of the slots in a 9246 optical library. The DB2 name of this table is SLOT. There is a unique index defined on the slot name in combination with the library name.
Note: The 9246 optical library is no longer supported.
Volume: Contains one row for each optical disk volume. The DB2 name of this table is VOLUME. There is a unique index on the volume serial number.
Deleted-Objects: Contains one row for each object waiting to be deleted from 3995 rewritable optical media. The DB2 name of this table is DELOBJT. There are two indexes defined on the table; one is unique and one is not.
Tape Volume: Contains one row for each tape volume used by OAM for object storage. The DB2 name of this table is TAPEVOL. There is a unique index on the volume serial number.
File System Delete: Contains one row for each object waiting to be deleted from the file system. The DB2 name of this table is FSDELETE.

Table 1 provides DASD space recommendations for storage of the CBROAM tables.

Table 1. CBROAM space recommendations
Description	DB2 name	Primary space 3390 tracks	Secondary space 3390 tracks
Library Table	OCLIBTSP LNAMINDX	1 1	1 1
Drive Table	OCDRVTSP DNAMINDX DRIDINDX	5 1 1	1 1 1
Slot Table	OCSLTTSP SLIBINDX	1 1	1 1
Volume Table	OCVOLTSP VSERINDX	20 2	10 1
Deleted-Objects Table	OCDELTSP DVOLINDX DELOINDX	100 10 100	10 5 10
Tape Volume Table	OCTVLTSP TVOLINDX	10 2	1 1
File System Delete Table	OCFSDTSP FSDTINDX	100 10	10 5

These recommendations allow:

216 optical library definitions
1␠320 drive definitions
1␠404 slot definitions for as many as twenty-two 9246 library definitions
5␠040 volume definitions
39␠600 objects waiting for deletion from rewritable optical media
5␠280 tape volumes to be used for storing objects
34␠900 objects waiting for deletion from the file system

If you do not use a particular level or sublevel of the OAM storage hierarchy, then you can use minimal space values for the tables related to that level or sublevel. For example, if the file system sublevel is not implemented in your installation, then use 1 for the primary and secondary space values for the File System Delete Table and the associated index.

If your installation requires more entry space or if you are using DASD storage that allows fewer than twelve pages per track, the above space recommendations might need to be increased.
