Common utility tables

The BMC common utility tables contain information about the BMC utilities that you generate and submit through a BMC utility product.

The following table lists the tables that each utility uses and each table’s default name and synonym:

Table	Default name	Synonym	Utilities that use this table
BMCDICT	CMN_BMCDICT	BMC_BMCDICT	LOADPLUS REORG PLUS
BMCHIST	CMN_BMCHIST	BMC_BMCHIST	CHECK PLUS BMC AMI Copy LOADPLUS BMC AMI Recover REORG PLUS UNLOAD PLUS
BMCLGRNX	CMN_BMCLGRNX	BMC_BMCLGRNX	BMC AMI Copy Log Master BMC AMI Recover BMC AMI Recovery Manager
BMCSYNC	CMN_BMCSYNC	BMC_BMCSYNC	CHECK PLUS BMC AMI Copy DASD MANAGER PLUS (BMCSTATS) LOADPLUS BMC AMI Recover BMC AMI Recovery Manager REORG PLUS UNLOAD PLUS
BMCTRANS	CMN_BMCTRANS	BMC_BMCTRANS	Log Master BMC AMI Recovery Manager
BMCUTIL	CMN_BMCUTIL	BMC_BMCUTIL	CHECK PLUS BMC AMI Copy DASD MANAGER PLUS (BMCSTATS) LOADPLUS BMC AMI Recover BMC AMI Recovery Manager REORG PLUS UNLOAD PLUS
BMCXCOPY	CMN_BMCXCOPY	BMC_BMCXCOPY	BMC AMI Copy Log Master BMC AMI Recover BMC AMI Recovery Manager REORG PLUS UNLOAD PLUS

Warnings and considerations for common utility tables

This section describes important information that you need to know when using the common utility tables.

Warning

The following warnings apply to the common utility tables:

Do not run LOADPLUS, REORG PLUS, or UNLOAD PLUS against the BMC common utility tables or table spaces. Doing so can cause unpredictable results.
Because BMC AMI Recover uses BMC tables during the recovery process, you cannot use BMC AMI Recover to recover any BMC table except the BMCHIST table.
Do not run the RUNSTATS utility against the BMC common utility tables. Doing so can negatively impact utility performance.
We strongly recommend that you use the ISOLATION (UR) bind option and issue SQL COMMIT statements when querying the tables in the BMC database. If objects in the BMC database are restricted for UPDATE, the executing BMC utilities might not be able to complete successfully.

Note the following considerations:

Some columns in the tables are present for compatibility with specific BMC utilities and are not used by all of the utilities.
If you have applications that depend on the structure or content of these tables, be aware that these tables are subject to change.
In general, the utility tables should not require maintenance, with the exception of BMCHIST.
You should back up the BMC table spaces on a regular basis to enable recoveries. If you use BMC AMI Copy as the copy utility, you must use SHRLEVEL CHANGE for the following spaces:
- BMCUTIL
- BMCHIST
- BMCSYNC
- BMCXCOPY
Supported versions of the following BMC products support the LOCKROW installation option:
- CHECK PLUS
- LOADPLUS
- REORG PLUS
- UNLOAD PLUS
If the value of the option is YES (which is the default value), the products use MVS enqueues instead of SQL LOCK TABLE statements to serialize updates to the BMCSYNC and BMCUTIL tables.
The following BMC products always use MVS enqueues for serialization when updating the BMCSYNC and BMCUTIL tables:
- BMC AMI Copy
- DASD MANAGER PLUS
- BMC AMI Recover
