A. EEM performance tuning ( if EEM is hooked up with external LDAP ) :
1) login EEM UI as EiamAdmin ( Global )
2) go to Configure -> User Store -> Group Configuration
set Group Resolution Level as "Resolve direct groups" instead of default "Resolve nested groups"
set Application Resolution Level as " Resolve direct groups" instead of default "Resolve nested groups"
3) go on EEM server to enable paging on EEM :
In server.xml under ...\CA\SC\EmbeddedEntitlementsManager\config\server\
save it and recycle EEM service , and after that , make sure you can login EEM UI as EiamAdmin
B. catalog performance tuning on viewService.conf , ehcache.xml , config.properties, server.xml accordingly
1) in config.properties under USM_HOME :
db.max.conn.pool.size needs to set reasonable big . default is 100, you may change it to 300 or 500 .
2) in viewService.conf under USM_HOME\view\conf\
set wrapper.java.maxmemory reasonable . The configurable parameter defines the max RAM that catalog application can use on the machine . You need to give enough RAM for catalog application to use .
3) in server.xml under USM_HOME\view\conf\
In http or https connector setting , make sure maxThreads is set reasonably . For example , default is 400 . You may set it as 800
4) ehcache.xml under USM_HOME\view\conf\
Please refer the tecdoc regarding "Form Caching feature in ehcache.xml and its impact":
Note : you will need to recycle catalog service after performance tuning above
C: Intensive web service calls made to catalog
In view.log , if you find that view.log fills up very quickly with the following error messages repeatedly and frequently , for example :
2018/12/17 126.96.36.1999 ERROR [http-nio-8080-exec-10] [RequestServiceImpl] SOAPREQ010 com.ca.usm.common.CommonException: You do not have access rights to view this request.:276483 at com.ca.usm.billing.ServiceManager.RequestValidator.validate(RequestValidator.java:75) at com.ca.usm.soap.services.RequestServiceImplUtil.validateAccessControl(RequestServiceImplUtil.java:890)
It is likely that other products make web service calls to catalog intensively and constantly , to extent , it could hammer the catalog system . You need to find out where and which application makes those web service calls to catalog . A typical example : if you have OOTB service desk and service catalog integration ( i.e. the integration without using PAM processes ) , you may have the attachment, log, note sync up going on from service desk tickets to catalog requests on Service Desk side :
In Service Desk UI , Administration -> Options Manager -> CA Service Catalog , there are a couple of configurable parameters relating to OOTB service desk and service catalog integration . If those parameters are installed ( turned on ) , one of them is casc_ws_retry :
Enter the no. of retries to synchronize a CA SDM ticket update (activity logs, attachments or status) with CA Service Catalog, in case of failure. Default:0. Enter -1 to try indefinitely.
If the service desk tickets to catalog requests' sync up needs to turn on , you may reduce the number of retries (casc_ws_retry) mentioned above , for example , set as 1 or 2 or 3 , but never set it as -1 ( which is going to retry forever ) .
If your site doesn't really need this sync up at all , please simply uninstall all the parameters under Administration -> Options Manager -> CA Service Catalog via Service Desk UI and recycle service desk service to turn off it .
