=========
The typical activity switches for the TIBCO Messaging Appliance P-7500 redundancy facility includes a failure activity switch and a recovery activity switch as stated in the TMA operation guide. In the lab we can simulate these two switches using TMA CLI.
1). Initially, each TMA system of the redundant pairs has one primary router active and backup server standby. Give an example of a pair of redundancy, TMA3 and TMA12. The status of redundancy are as follows before switching:
======================================================================
tma3.na.tibco.c(config-router-redundancy)# show redundancy
Configuration Status: Enabled
Auto Revert: Yes
VRRP Interface Status: Up
Primary CVRID Backup CVRID
--------------------- ---------------------
CSMP Virtual Router Id 10.97.48.57 10.97.48.23
Activity Status Local Active Mate Active
VRRP Status Master Backup
Local Priority Active Standby
Primary Router 10.97.48.57
VRRP Virtual Router Id 57 23
Last Update Status Ok Ok
tma12.na.tibco.(config-router-redundancy)# show redundancy
Configuration Status: Enabled
Auto Revert: Yes
VRRP Interface Status: Up
Primary CVRID Backup CVRID
--------------------- ---------------------
CSMP Virtual Router Id 10.97.48.23 10.97.48.57
Activity Status Local Active Mate Active
VRRP Status Master Backup
Local Priority Active Standby
Primary Router 10.97.48.23
VRRP Virtual Router Id 23 57
Last Update Status Ok Ok
========================================================================
2). Log on to the TMA system you want to switch activity out, say, TMA3, with user admin and enter the mode of router redundancy as follows:
======================================================================
tma3.na.tibco.c> enable
tma3.na.tibco.c# config
tma3.na.tibco.c(config)# router redundancy
tma3.na.tibco.c(config-router-redundancy)
======================================================================
Enter "release-activity" to surrender activity to the mate router, TMA12, for all virtual router ids. The status of redundancy of TMA3 will become:
======================================================================
tma3.na.tibco.c(config-router-redundancy)# show redundancy
Configuration Status: Released
Auto Revert: No
VRRP Interface Status: Up
Primary CVRID Backup CVRID
--------------------- ---------------------
CSMP Virtual Router Id 10.97.48.57 10.97.48.23
Activity Status Mate Active Mate Active
VRRP Status Backup Backup
Local Priority Release Release
Primary Router 10.97.48.57
VRRP Virtual Router Id 57 23
Last Update Status Ok Ok
========================================================================
3). Log on TMA12 as user admin and check the redundancy status as follows: =====================================================================
tma12.na.tibco.(config-router-redundancy)# show redundancy
Configuration Status: Enabled
Auto Revert: Yes
VRRP Interface Status: Up
Primary CVRID Backup CVRID
--------------------- ---------------------
CSMP Virtual Router Id 10.97.48.23 10.97.48.57
Activity Status Local Active Local Active
VRRP Status Master Master
Local Priority Active Active
Primary Router 10.97.48.23
VRRP Virtual Router Id 23 57
Last Update Status Ok Ok
======================================================================
4). Next, to recover the activity on TMA3 enter "no release-activity" on TMA3, and the activity is returned back to TMA3. The redudancy status will revert to the initial one.
Note: if the "Auto Revert" is "No", it indicates the backup router won't automatically give up activity if primary router is ready to provide service. In our example, it means you have to run "auto-revert" on TMA2 to flip it to "yes". Otherwise, "no release activity" won't recover activity on TMA3.
