Enabling interop text mode support in older VOBs

About this task

VOBs created by recent releases of DevOps Code ClearCase® are compatible with views in any text mode. VOBs created in earlier versions of the product are compatible only with views in transparent text mode until you run the msdostext_mode command on the VOB.

Only the VOB owner or a privileged user can run msdostext_mode. The command syntax is

ccase-home-dir/etc/utils/msdostext_mode [ –d ] vob-storage-pname

With no options, msdostext_mode does the following:
  • For all versions of all file elements whose element type is text_file or a subtype of type text_file, generates and stores in the VOB database the information required to support access to these versions by views created in strip_cr or insert_cr text modes.
  • Turns on support for strip_cr and insert_cr text modes, so that this information is recorded for newly created versions.

With the –d option, msdostext_mode disables support for strip_cr and insert_cr text modes.

The msdostext_mode command does not convert or modify files in any way. It affects only the information recorded for text file versions in the VOB database.
