This section describes how the Accelerator Plus administrator can use
the file $VOVDIR/local/vnclist.config.tcl to modify some defaults for the wx
list command. This file does not exist by default; it must be created when
needed.
Enable List Cache
By default, list results are obtained from the server in real-time. In large-scale
workload environments, repeated queries can impact server performance. To reduce
this impact, a list result cache can be enabled:
set NCLIST(cache,enable) 1
Configure List Cache Expiration
If the list cache is enabled, list results will be written to a client-side file, and
subsequent list requests will be obtained from this file, up to the cache
expiration. The default expiration is 30s from creation. After this time, the cache
file will be regenerated upon the next list request. To set the cache expiration to
a different value:
set NCLIST(cache,timeout,default) 60
Disable Listing by Job Name
Another list operation that can affect server performance in a large-scale workload
environment is listing by job name. This is due to the need to compare string values
across many jobs. Listing by job name can be disabled entirely, this way:
# Fragment of $VOVDIR/local/vnclist.config.tcl
set NCLIST(listbyjobname,enable) 0
