Db2inidb ts1 as standby

6.Start the DB2 instance db2ts1 on the Backup server: db2start

7.Place the Backup database into a rollforward pending state, and take it out of its

suspended state:

8.As DB2 log files are successfully getting archived to the archive directory on the Primary database, make them available to the retrieve path for the Backup database. Be careful not to roll forward through a log file on the Backup server that is only partially copied to the retrieve directory.

9.On the Backup database, roll forward through the DB2 logs that have been archived from the Primary database. The rollforward command gives you the options to roll forward to end of logs or to a point in time. Rolling forward to a point in time can be useful if the intention is to keep the Backup database a constant amount of time behind the Primary database:

db2 “rollforward database ts1 to end of logs”

db2 “rollforward database ts1 to 2000-06-19- 19.56.00.0000”

Note: The retrieved log files are copied to /db2/TS1/log_dir by DB2 during the rollforward, which is the current mount point for the log directory. Ensure that the instance owner has write access to this directory and that the directory is large enough. When the log logical volume is copied, and /db2/TS1/log_dir is mounted, the contents of the /db2/TS1/log_dir mount point will no longer be visible. This does not cause a problem, because any log files that may have been in this directory can still be retrieved from the retrieve path.

10.Continue with iterations of the previous rollforward commands until the Primary database fails, a database application logic error occurs, or until use of the Backup database is desired.

If you do not need to roll forward through the most current logs from the Primary system, then proceed to step 16.

11.At this point, ensure all log files that have been archived on the Primary server are available to the Backup server.

12.Copy the log pair from the Primary server:

/usr/opt/ibm2105cli/rsExecuteTask.sh –v –s ESSCSS

ts1dblog

and wait for FlashCopy task to finish.

13.Mount the log filesystem on the Backup server: mount /db2/TS1/log_dir

14.Issue a rollforward stop command on the Backup database. If a database application logic error occurred, the user must rollforward to a point-in-time
