Start IR Asynchronous mode

Applies to User Roles:

System Administrator

Asynchronous IR means that instead of every session directly updating IR indexes as data is updated, the IR index changes are logged to an internal table (irqueue), and a background process performs all the IR index updates separately.

To start asynchronous IR:

Stop all HPE Service Manager servers running a horizontal scaling or classic load manager implementation.
Open the Service Manager initialization file (sm.ini) on each system and add the following line.
ir_asynchronous:1
Note: You must add this parameter to each system running in a horizontally scaled implementation so that each server knows that the IR process is running asynchronously.
Save the initialization file.
Open the Service Manager configuration file (sm.cfg) on the system running the load balancer process and add the following line.
sm -que:ir
Save the configuration file.
Restart the Service Manager servers.
