Error description
MVFS view-extended ClearCase operations incur greater than 50 percent overhead than setview operations on AIX
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: * **************************************************************** In ClearCase running on AIX, when there are a large number of VOBs mounted (e.g., hundreds in some customer cases) and the user is cd'd into a view-extended directory pathname and uses the getwd() call to find the current directory pathname (e.g., the /bin/pwd command), they may experience a long delay (many seconds) before getting the current directory pathname (e.g., seeing the pathname from /bin/pwd).
Problem conclusion
This is fixed by a combination of ClearCase 7.1.2.9 or 8.0.0.5, together with an AIX kernel patch. These patches be installed independently, but the performance improvement won't be seen until both changes are installed. The AIX kernel APARs containing the AIX changes are: IV22023 (for AIX 5.3 TL12) IV31361 (will be AIX 6.1 TL8) IV31359 (will be AIX 7.1 TL2) IV31750 (will be AIX 6.1 TL9)
