TSM Server Configuration
For demonstration purposes, I have created one multimode
DB2 database named ARTIST, belonging to the TSM API configuration on the
ARTIST_DB2 server machine, running on a SUN Solaris operating system. The TSM
administrators are responsible for the TSM server organization and configuration
, however, they need clear, technical input from the DB2 administrators. The
allied forces of the DB2 and TSM administrators have resulted in the following
exhibit TSM standards and configuration used in this article:

Figure 3. The TSM System configuration files and settings, used
during article test case.
a.)
The node ARTIST_DB2 has been assigned to the policy domain
DB2, which has been created on the TSM server for handling the DB2 backup and
archive data.
b.)
The following
is a configuration review, taken directly from the TSM server configuration
database listing the new node ARTIST_DB2 on Sun Solaris, and belong to the
policy domain DB2:

Displaying
newly defined management classes MGMT_BACKUP and MGMT_LOGS on the TSM server
associated with the new DB2 policy domain:
tsm> q mgmt
Node Name: TESTTSM001
Domain Name : DB2
Activated Policy Set Name : PSDB
Activation date/time : 01.01.2004 16:42:33
Default Mgmt Class Name : MC3650
Grace Period Backup Retn. : 9999 day(s)
Grace Period Archive Retn.: 9999 day(s)
MgmtClass Name : MGMT_BACKUP
Description : MC for DB2 backups
MgmtClass Name : MGMT_LOGS
Description : MC for DB2 logs
MgmtClass Name : MC365
Description : MC for 365 days
MgmtClass Name : MC3650
Description : MC for 3650 days
The newly created management class, MGMT_BACKUP, is the
backup management class, with the associated copy group. The backup copy group
has the following fixed retention settings:
VEREXISTS=1 - every database backup has unique
name, duplicated backups will be deleted, backup is kept according definition
for the management class
VERDELETED=0 deleted backup are automatically
expired from TSM server
RETONLY=0 - inactive, expired backups are deleted
automatically
The new archive management class, MGMT_LOGS, has similar
technical characteristics to the backup management class, MGMT_BACKUP, with one
important exception.
Archive logs are kept on the TSM server for a strictly
defined period only. Upon expiration, the TSM will automatically delete archived
objects. Manual clearing of archive log files from the TSM server using the DB2
commands is prohibited. Supplementary, duplicate archive log files are
accepted, something that is not permitted for the backup management class. The
archive copy group has the following defined retention settings:
RETVER=NOLIMIT

As a last bit
of information, the storage pools listing from TSM server:
tsm> q stgpool
Storage Device Estimated Pct Pct High Low Next
Pool Name Class Name Capacity Util Migr Mig Mig Storage
(MB) Pct Pct Pool
----------- ---------- ---------- ----- ----- ---- --- -----------
BACKUPPOOL DISK 2,048.0 0.0 0.0 80 20 TAPEPOOL

TAPEPOOL1 MAGSTARMP 75,295.0 25.2 100.0 90 70
The archived log files are saved in the ARCHPOOL TSM
storage pool, and the database backup files are saved in the BACKUPPOOL storage
pool.
