About checkvob

VOBs have complex internal and external relationships that can sometimes be disrupted by system or network failures or when a VOB is restored from backup. checkvob is a cleartool subcommand that can find, and in many cases fix, a variety of problems in these relationships.

checkvob can find and often fix these problems:
  • Inconsistencies between a VOB’s database and its pools
  • Improper protections on storage pools
  • Improperly configured AdminVOB hyperlinks
  • Local types that eclipse global types
  • Broken cross-VOB hyperlinks, including those that link UCM components to PVOBs.
You can use checkvob for a variety of purposes:
  • When you restore a VOB from backup media without using vob_restore (the vob_restore script runs checkvob as part of its normal operation)
  • When you move a VOB
  • As part of your periodic VOB maintenance routine
