Xcelsius Cache Server Setting Time in cache

Former Member

Hi

I have Setup the Xcelsius Cache Server and Processing Servers within Business objects enterprise (available as part of latest BO Service pack) and all appears to be working when accessing data via QWAAS connections within the xcelsius. However the cache server seems to be generating new cache files every 20 minutes. From reading the supporting documentation . The documentation indicate that the session timeout as defined in advanced properties of the QWAAS wizard should determine the length of time that the query remains within the xcelsius cache server.

Has anyone had an experience with setting up the excelsius cache server.

Thanks

There are two kinds of cache in Xcelsius cache server:

1, security cache which will cache query meta data. the default cache time is 20min. and you can modify it by adding '-securityCacheTimeOut' in the Xcelsius cache server command line if you REALLY want to. (time by second)

2, data cache which, as the document said, is controlled by the 'session timeout' property from the Qaaws side to keep it consistent with Qaaws configuration. you can control the cache of each qaaws there.

so the cache files created each 20 minutes by Xcelsius cache server are probably for security cache.

After you enable the QaaWS Accelerator, it is Xcelsius Server handling the query result cache.

To modify the cache and process server default settings, you may launch CMC, go to Servers->Server List and then Properties for Xcelsius servers.

The cache timeout option is called "Oldest On-Demand data Given to Clients(seconds)". You will need to change the setting for both Xcelsius Cache and Processing server.

hope it helps,

Thanks Donna,

That is the sort of parameter i was looking for, however after installing th xcelisus servers and displaying the properties of both the cache server and the xcelsius processing server neither have a property relating to oldest data. The only properties that can be set for the cache server are idle connection time out, cache size, and cache location
