Update the first BSDS with the new alias and correct data
set names for the active logs. In this step, you do not attempt to
change the names of existing archive log data sets.
Before you begin
If these catalog entries or data sets will not be available
in the future, copy all the table spaces in the Db2 subsystem to establish a new recovery point.
You can optionally delete the entries from the BSDS. If you do not
delete the entries, they will gradually be replaced by newer entries.
Procedure
To update the BSDS:
- Run the change log inventory utility (DSNJU003).
Use
the new qualifier for the BSDS because it has now been renamed. The
following example illustrates the control statements required for
three logs and dual copy is specified for the logs. This is only an
example; the number of logs can vary and dual copy is an option. The
starting and ending log RBAs are from the print log map report.
NEWCAT VSAMCAT=newcat
DELETE DSNAME=oldcat.LOGCOPY1.DS01
DELETE DSNAME=oldcat.LOGCOPY1.DS02
DELETE DSNAME=oldcat.LOGCOPY1.DS03
DELETE DSNAME=oldcat.LOGCOPY2.DS01
DELETE DSNAME=oldcat.LOGCOPY2.DS02
DELETE DSNAME=oldcat.LOGCOPY2.DS03
NEWLOG DSNAME=newcat.LOGCOPY1.DS01,COPY1,STARTRBA=strtrba,ENDRBA=endrba
NEWLOG DSNAME=newcat.LOGCOPY1.DS02,COPY1,STARTRBA=strtrba,ENDRBA=endrba
NEWLOG DSNAME=newcat.LOGCOPY1.DS03,COPY1,STARTRBA=strtrba,ENDRBA=endrba
NEWLOG DSNAME=newcat.LOGCOPY2.DS01,COPY2,STARTRBA=strtrba,ENDRBA=endrba
NEWLOG DSNAME=newcat.LOGCOPY2.DS02,COPY2,STARTRBA=strtrba,ENDRBA=endrba
NEWLOG DSNAME=newcat.LOGCOPY2.DS03,COPY2,STARTRBA=strtrba,ENDRBA=endrba
During startup, Db2 compares
the newcat value with the value in the system
parameter load module, and they must be the same.
- Using the IDCAMS REPRO command, replace the contents of
BSDS2 with the contents of BSDS01.
- Run the print log map utility (DSNJU004) to verify your
changes to the BSDS.
- At a convenient time, change the DD statements for the
BSDS in any of your offline utilities to use the new qualifier.
