Supported Upgrade Paths

IDIH 8.2.3.3 is compatible with DSR 9.0. If IDIH is a component of a Network Element, it should only be upgraded after the DSR upgrade.

Following are the steps to be followed after upgrading IDIH to 8.2.3.3.0_82.64.0:

1. Restart the ntp service on Application, Mediation, and Oracle Virtual Machines by running the following command:
   1. "/etc/init.d/ntpd"
2. Log in to Mediation VM as admusr and change to tekelec user, restart all mediation processes by running the following commands:
   1. pm.set off <process-name>
   2. pm.set on <process-name>
3. If <hostname> mapping does not exist for loopback IP and XMI IP in the /etc/hosts file, add the hostname as shown in the following example and restart the VM.

   Example:
   127.0.0.1   localhost localhost4 localhost4.localdomain4 <hostname>
   ::1         localhost localhost6 localhost6.localdomain6
   <int-ip-oracle>          oracle
   <int-ip-mediation>       mediation
   <int-ip-sppserver>       appserver
   <xmi-ip>                 <hostname>

4. If <hostname> mapping exists for loopback IP and XMI IP then no changes are required to be made in the /etc/hosts file.

   Note:

   It is a must to verify the mapping on Application, Mediation, and Oracle VMs.
