Information Retrieval (IR) expert parameters: ir_asynchronous

Parameter

ir_asynchronous

Description

This parameter defines whether the HPE Service Manager server immediately updates information retrieval files (synchronously) or whether the server creates a schedule record to process the files (asynchronously).

Caution Be aware that the synchronous IR mode could cause performance issues. For this reason, you are not recommended to change this parameter from its default value.

When the server is running in asynchronous IR mode, you can start the processing of scheduled IR records by using the sm -que:ir command. If the scheduled process stops without clearing the shared memory, you can start the process again by using the sm -que:ir command.

Valid if set from

Server's operating system command prompt

Initialization file (sm.ini)

Requires restart of the Service Manager server?

Yes

Default value

Possible values

0 (synchronous record handling)

1	Modify the content of the field in IR key	Yes	Yes
1	Regen IR	Yes	Yes
0	Modify the content of the field in IR key	No	Yes
