Queste informazioni sono disponibili solo in inglese.
The following is a quick checklist to run through if you are finding performance issues:
Database
- Clear down the tps_user_message table regularly.
- Archive or clear down outbound Mail Manager entries.
- Check for unbound collections: Community Article.
- Check whether Snapshot Isolation is enabled on SQL Server.
- Update statistics.
- Rebuild indexes on all tables regularly.
IIS
- Turn off Error logging on web sites.
- Turn off Log Site Visits on web sites.
- Consider splitting Service Desk Framework web sites for multiple users.
- Consider separate Service Desk Framework for Services on Application server.
- Ensure separate Application pools for Service Desk Framework and Web Access web sites.
- Set Application pools to recycle each night (or period of low usage) or not at all.
Servers
- Check specification against recommended technical specification guidelines.
- Check disk space (at least 10% free space on OS drives).
- Check memory and CPU usage during poor performance.
- Check Page file size (virtual memory) is set to at least the recommended size in Performance Options.
- Check the event logs for errors.
- Check for other applications that are running (virus scanners, etc). Consider testing with these switched off.
Network
- Check network traffic.
- Check Network Card (speed, usage etc).
- Check routers.
- Make sure a proxy server is not being used.
- Check ping timings from client to web server and web server to database server.
- Check the number of hops as above using tracert to make sure access is short and direct.
Service Desk Framework Configuration
- Ensure Diagnostic logging is switched off in all tps.config files.
- Consider disabling Process Workload business object.
- Increase timeout (see Gestione del timeout).
- Try using IP address in connect string rather than name.
Ivanti Console
- Consider using client side caching for console.
- Consider enabling compression for console if running over WAN.
- Consider loading query definitions from cache.
- Check if attributes on Incident windows set to 'Invoke Search' and consider changing setting or switching off.
- Check that tabs on Incident windows are not running large queries.
- Check dashboards do not contain lots of queries and that queries do not refresh.
- Check if large reports or queries are being run during periods of slow performance.
VMWare
- If you are running servers on VMWare, refer to the performance guides for VMWare Server.
