问题
I have a user who is getting an error when they are trying to access another's view. When they try to do a diff they input/output error on xcompare in unix and in windows they receive failed to display version tree browser for element Encountered an improper argument on the windows side. I have no issues doing this in either of the user's view. They both are a member of the correct group and the view was created with that group. What else could be wrong?
回答1:
It can depend on the exact version of your ClearCase.
For instance, this technote mentions (Windows)
When accessing a file or directory in the IBM Rational ClearCase GUIs, for example, ClearCase Explorer or the Version Tree Browser, that has permissions of 770, you will receive an error: "Encountered an improper argument" rather than "Access Denied" or "Permission Denied" if you are not a member of the group that owns the element.
While the users might be part of the correct group (ie their CLEARCASE_PRIMARY_GROUP) is the same as the Vob group), double-check their permissions and their view permission.
This technote details:
If a principal has not been granted access to a VOB, an attempt to access the VOB from IBM® Rational® ClearCase Explorer returns the error, "Encountered an improper argument."
This error might imply insufficient permissions.
To determine the effective ACL on the object, use the command:cleartool describe -eacl vob:\vobtag \vobtag
Regarding the view:
cd /path/to/my/view
cleartool lsview -l -full -pro -cview
A fix_prot on the view might be necessary: see an example of such a fix_prot in "While creating a view I got this error; cleartool: Error: Failed to record hostname in storage directory"
