1 Session: I03 TSM is not just a black box Carolyn Sanders EDS May 19, :30 p.m. 02:30 p.m. Platform: LUW 1

2 Little black box Humor If the "black box" flight recorder is never damaged during a plane crash, why isn't the whole airplane made out of that stuff? Black box" is a serious term with a specific meaning: a piece of hardware or software for which that if you input x it will always give output y but for which you have no knowledge of how the output is generated from the input. 2 2

3 Objectives 1. Verify your configuration of TSM for DB2 LUW 2. Monitor Backups and Archive logs within TSM 3. Determine the health of TSM 4. Perform Problem Determination 5. Verify your DB2 LUW recoverability from TSM 3 3

4 The question then becomes: how many boxes should you open and get to know the inner workings in order to be more effective? TSM 4 4

5 dsmadmc dsm.sys dsm.opt TSM API 5 5

6 What is API The DB2 LUW Interface for TSM communicates with the TSM server using the TSM API. 6 6

7 What is dsm.opt DB2 LUW Interface for TSM uses the client user options file (dsm.opt) who s location is defined in the userprofile DSMI_CONFIG. 7 7

8 What is dsm.sys DB2 LUW Interface for TSM uses client system options file (dsm.sys) located in the TSM API installation directory. 8 8

9 There are two dsm.sys ba/bin/dsm.sys ba/bin/dsm.sys 9 9

10 dsmadmc The administrative command-line client is a program that runs on a file server, workstation, or mainframe that allows administrators to control and monitor the server through administrative commands. You can start an administrative client session in console, mount, batch, or interactive mode by using the DSMADMC command. In each of these modes, you can specify certain options with commands. For details, see Using Administrative Client Options. You can redirect output to a file using redirection characters. To start an administrative client session in command line mode, enter this command on your workstation: dsmadmc -id=admin -password=admin To end an administrative command line client session by entering this command on your workstation: quit 10 10

16 To Display TSM node detail information $DSMI_CONFIG: Find TSM stanza name in $DSMI_DIR/dsm.sys Servername 16 16

17 To Display TSM node detail information in $DSMI_DIR/dsm.sys : Find TSM node used by TSM stanza for DB2 SErvername Node 17 17

18 To Display TSM node detail information $DSMI_CONFIG windows: Find DSMI_CONFIG in environment variables dsm.opt 18 18

19 To Display TSM node detail information in dsm.opt windows: Find TSM node dsm.opt Node 19 19

20 To determine if you have a backup running dsmadmc Node = Client Name 20 20

21 To Display TSM node detail information $DSMI_CONFIG LANFREE: Find TSM stanza name in $DSMI_DIR/dsm.sys Servername 21 21

22 To Display TSM node detail information $DSMI_DIR/dsm.sys LANFREE: Find TSM node used by TSM stanza for DB2 Servername Node 22 22

23 To determine if you have a LANFREE backup running dsmadmc <hostname>_sta 23 23

24 To determine if you have a backup running LANFREE dsmadmc <hostname>_sta 24 24

25 To determine if you have a backup running LANFREE dsmadmc X Node userid 25 25

26 To determine TSM drives are online dsmadmc 26 26

27 To determine if TSM path is online dsmadmc 27 27

28 To view TSM activity log dsmadmc Node 28 28

29 Display TSM node detail information dsmadmc Node Policy 29 29

30 Display TSM node detail information dsmadmc Node Policy 30 30

31 Display TSM node detail information dsmadmc: Find the Number of TSM mount points allowed 31 31

32 Display TSM node detail information dsmadmc: Backup Delete Allowed should be set to yes 32 32

33 Determine Retention Period set in TSM for DB2 dsmadmc : Find management class for the policy domain Policy Mgmtclass Name 33 33

34 Determine Retention Period set in TSM for DB2 backups dsmadmc: Display retention for the policy domain and management class Policy + Mgmtclass Name 34 34

35 Determine Retention Period set in TSM for DB2 backups: Recommend settings for DB2 Backups The following retention settings should be used for the management class that will be bound to the DB2 backups: VEREXISTS=1 Keeps only one version of the backup file as the name of the backup is unique. (There will not be a newer version of the backup image with the same name). VERDELETED=0 If the backup file has been deleted (via db2adutl), then Tivoli Storage Manager should not keep an inactive version of this file. RETEXTRA=0 (the same value as RETONLY) RETEXTRA parameter will never be used as you will never have more than one version of the backup file. To prevent confusion set this parameter to the same value as RETONLY. RETONLY=0 When a backup image file becomes inactive it will be purged from the Tivoli Storage Manager server at the next expiration

36 Determine Retention Period set in TSM for DB2 archive logs dsmadmc Display retention for the policy domain, management class, and type archive Policy Mgmtclass Name 36 36

37 Determine Retention Period set in TSM for DB2 archive logs You should set the retention for the archive copy group to nolimit. RETVER: NOLIMIT 37 37

38 Determine the number of TSM scratch tapes dsmadmc libvolumes 38 38
