Common Agent problems

Use this information to solve performance problems related to common agent services (CAS) in the IBM® Flex System Manager management software.

Table 1. Common Agent problems and corrective actions
Problem description Corrective action
You experience either of the following problems:
  • VIOS performance is sluggish after it is started.
  • The following error is displayed after Common Agent (or CAS) is restarted:
    SEVERE: ALR0412E: The authorization property 
com.ibm.lwi.localhost was not found in 
/var/opt/tivoli/ep/conf/admin/adminAuth.properties
 The reason for the problem might be that the Domain Name Server (DNS) that is configured to provide hostname resolution to VIOS is offline. The name resolution order in VIOS is set to bind the hosts by default, which causes CAS to timeout when trying to resolve the hostname from DNS before it gets the hostname from the local hosts file.
To change the DNS hostname resolution and fix the problem, complete the following steps on the managed endpoint that has the error or poor performance:
  1. If CAS is running, stop CAS. See the first step in Restarting Common Agent for more information about how to stop CAS.
  2. Add the local host to the \etc\hosts directory on the managed compute node.
    1. Open the local hosts file on the compute node operating system.
    2. Add an entry in the hosts file for the local hostname and IP address. The entry might be similar to the following: 
      172.16.254.1	  localhost
      where 172.16.254.1 and localhost are the IP address and hostname of the local host.
    3. Save and close the hosts file.
  3. Change the host order in the /etc/netsvc.conf configuration file to local,bind:
    1. Open the /etc/netsvc.conf file on the compute node operating system.
    2. Add the following entry:
      hosts=local,bind
    3. Save and close the configuration file.
  4. Start CAS. See Restarting Common Agent for more information about starting CAS.
