Upgrading the Agent

This section describes how to upgrade from the VCS enterprise agent 3.5 for Oracle in a VCS cluster.

1. Save the VCS configuration and stop the VCS engine.
     # haconf -dump -makero
     # hastop -all -force
2. Back up the configuration file, main.cf to a location on the cluster node.
3. Follow step a through step c on all systems on which the Oracle agent was installed.
   1. Remove the Oracle agent.
   
      # swremove VRTSvcsor
   2. Delete the file /etc/VRTSvcs/conf/config/OracleTypes.cf.
   3. Install the VCS enterprise agent 4.1 for Oracle. See Installing the Agent Software for instructions.
4. Copy the file OracleTypes.cf from the directory /etc/VRTSvcs/conf/ to the /etc/VRTSvcs/conf/config directory.
5. Copy the main.cf from the backed up location to /etc/VRTSvcs/conf/config.
6. Edit the main.cf located under /etc/VRTSvcs/conf/config.

   Replace all resources of type Sqlnet with resources of type Netlsnr. See Resource Type Definitions for information about the attributes in this version of the Oracle agent.

   # cd /etc/VRTSvcs/conf/config
   # hacf -verify
