When the host server for CA Performance Center runs a dual NIC it has been observed that after a restart of the server the IP address CA Performance Center uses changed.
How does CA Performance Center select the IP address of its host in dual NIC configurations?
To override what gets set use the SsoConfig tool. When running SsoConfig, enter 1 for PC, then 3 for PC settings. Within are two values involved, the Web Service Host and Web Site Host values. By default these are set in the netqosportal MySql DB in CAPC. They are found in the performance_center_properties table as field names NpcWebServiceHost and NpcWebSiteHost. They can have three possible Priority values. They are:
1 and 2 map back to the options for where user updates can be made via the SsoConfig CLI tool.
During the sync process during the PC restart, where it’s doing this IP check, it will always write to those 2 attributes at Priority Level 0, the IP that JDK gives back.
The values we sync to the other data sources themselves will come from the Remote Value (Priority 1) that the user can override with a specific IP. This would be the IP you would want things communicating to the PC server on all the time.
Changing the remote values should not require a restart of the services. They should take effect the next sync cycle for the various data sources. You can check Priority 0 is still possibly getting updated, but data_sources2 table in netqosportal has an entry for PC and it should be the remote value, and every sync after that, it should still be the remote value.
Check the URL http://DA:8581/rest/dataaggregator to see what NpcHostName is synced down to the DA.
If for some reason PC didn’t reread the values from performance_center_properties restart the PC services.
