[ClearCase] How to change UNIX UID and GID for all objects within one VOB?

Question

Subject:

How to change UNIX UID and GID for all objects within one VOB?

Senario:

User wants to change UNIX group from GRP01 to GRP02 for all ClearCase objects in one VOB.

It often happens in design team organization changes.

Solution:

Most CM admin may want to use cleartool project to change UNIX Group, but it is not recommended by IBM Rational ClearCase.

Actually, IBM provided special tools vob_sidwork and vob_siddump to implement UNIX UID and GID changes during VOB data migration from one organization to another one.

Following is a example from my common works recently.  I use the tool vob_sidwalk changed UNIX group from GRP01 to GRP02.

This is a simple example for your referrence. For detail usage, please check the manual of vob_sidwalk.

# the first command is used to change all objects which owner is unknow to default vob administrator.
/opt/rational/clearcase/sun5/etc/utils/vob_sidwalk -unknown -execute /vobs/testvob  /tmp/vob_sidwalk_unknown_testvob

# the file /tmp/groups.txt is used to map old GID 233 to new GID 232
# cat /tmp/groups.txt
domain/GRP01,GROUP,UNIX:GID-233,domain/GRP02,GROUP,UNIX:GID-232
#

# the 3rd command is used to change GID on all objects within the vob /vobs/testvob according the map file /tmp/groups.txt
/opt/rational/clearcase/sun5/etc/utils/vob_sidwalk -map /tmp/groups.txt -execute /vobs/testvob /tmp/vob_sidwalk_map_testvob

# the 4th command is used to change VOB container's GID
/usr/atria/bin/cleartool protectvob -chgrp GRP02 /vobs/testvob
