Solution 2226827.1 : Oracle Key Manager (OKM) - Potential Timeouts During Join Cluster Of New T7-1 KMA's To Existing X2100/X2200 M2 KMA Cluster

Applies to:

Oracle Key Manager - Version 3.0 and later
Information in this document applies to any platform.

Symptoms

There have been some instances where timeouts are observed when a new NS T7-1 KMA is joining a cluster with x2100/x2200 m2 KMA’s, because the x2100/x2200 m2 platforms are too slow and the T7-1 KMA's sometimes times out as if the x2100/x2200 KMA's are not responding.

Cause

x2100/x2200 m2 KMA performance

Solution

The recommendation is to utilize the Initial Replication Acceleration feature during the join cluster operation.

From the OKM 3 Administration Guide located here:

http://docs.oracle.com/cd/E50985_03/index.html

Reference the "Joining an Existing Cluster" section starting on page 49.

Specifically in Step 9, make sure to answer yes "Y" for the following question:

It might take some time for this KMA to be updated with information from other
KMAs in the Cluster. This amount of time can be greater in Clusters that have
more KMAs or when the KMAs have been online for a long time.
To accelerate these initial updates (that is, to catch up now), you can choose
now to download a backup from another KMA in the Cluster and then restore from
it. There will not be an opportunity to accelerate these updates later.
Catch up now? [y/n]:

9. Type y to accelerate initial updates.
