Symptoms
Switching from the POA Control Panel to PBA works slowly, it takes up to 30-60 seconds to open PBA CP.
Cause
One of the possible reasons is that POACPor POA UI server can not resolve hostname or IP address of the PBA Application server in timely manner. You may check it logging into the POA Control Panel server by SSHand trying to run the commands below:
# host PBA_SERVER_HOSTNAME
# host PBA_SERVER_IP_ADDRESS
where PBA_SERVER_HOSTNAME and PBA_SERVER_IP_ADDRESS are hostname and IPaddress of the PBA server respectively.
Same check should be performed on POA UI server.
If the commands above take significant time to complete then we will have delays in switching from POACPto PBA.
The reason might be the fact that incorrect or non-fuctioning DNSserver is configured on the POA CPor POA UI server.
Resolution
To resolve the problem you need to correct DNSresolving on the POACPserver so that it can resolve hostname and IPaddress of the PBA server - set correct DNSserver in the /etc/resolv.conf file on the POACPand/or POA UI server.
Another possible solution is to add IP address and hostname of the PBA server to the local hostsfile on the POA Control Panel server and/or POA UI server.
