I have just recently successfully migrated our Traveler 9.0.1 “Standalone” server to “HA Cluster” mode (using IBM DB2 as the back-end DB), however the new additional Traveler server does not appear to have any users/devices registered (0 users/devices), and only the original Traveler server shows all users registered.
Here’s a summary of the steps I followed:
1 - Converted the current standalone Traveler server to HA Cluster mode (using the travelerUtil.cmd command). Confirmed the server was successfully connected to the DB2 Database server.
2 - Ran up a new Traveler server (initially just as a Standalone server, as per IBM documentation).
3 - Converted the new additional Traveler to HA Cluster mode (using the travelerUtil.cmd command). Confirmed the server was successfully connected to the DB2 Database server.
When I run a “tell traveler hadr show” command (to see the HA Cluster details), it shows both servers successfully registered to the HA pool, and shows the new additional server as having 100% “Availability Index”. However it shows the number of Users and Devices both showing as zero for the new additional Traveler server (the original Traveler server still shows all users/devices registered as per normal).
The only thing I have not done is add the new Traveler server to the “pool” in the IP sprayer / load balancer, as I’m hesitant on doing that until I’m confident the new traveler server is seeing all of the users/devices.
Details of servers: 2 x Domino 9.0.1 FP3 / Traveler 9.0.1 FP5 running on Windows Server 2008 R2 - 1 x IBM DB2 (Work Group Edition) 10.1 FP4 running on RHEL Linux 6.6.
If anyone else has had similar problems, or have any ideas, your feedback would be very much appreciated. Thanks in advance.
