32.1 Minimize Process Overhead

The most effective measures for ensuring good performance from VOB hosts are also the easiest to implement:

• Keep non-ClearCase processes off the VOB host. Don't use the VOB host as a server host for another application (for example, a DBMS or Web Server) or for a critical network resources such as an NIS server on UNIX or a Primary Domain Controller on Windows.

• Keep ClearCase client processes off the VOB host. Do not use the VOB server host for other ClearCase tasks such as building or other CM activities (diff/merge, cleartool find, and so on). The VOB server host should not also be used as a developer's desktop system.

• Keep view_server processes off the VOB host. This recommendation may be harder to implement; many organizations create shared views on the same hosts as VOBs. If possible, minimize this double use of VOB hosts.

EXCEPTION: For reliable non-ClearCase access (avoiding multihop network access paths), place the VOB and the view through which it is exported on the same host. For more information, see Setting Up an Export View for Non-ClearCase Access.
