SW_SET_PRIORITY

The SW_SET_PRIORITY procedure sets the internal message queue priorities. The procedure only changes the priority of the messages SSOLite sends. It does not change the SW_CP_VALUE and SW_IP_VALUE. So any subsequent messages for that case will remain at the default level or will be processed in the order of SW_CP_VALUE or SW_IP_VALUE when using iProcess Workspace (Windows) to process work items.

Syntax

SW_SET_PRIORITY (
message_priority smallint)

where:

•

message_priority is the priority value.

You can set priorities ranging from 1 to 999, where 1 is the highest priority, for internal message queues when passing messages between iProcess processes such as from the Background process to WIS processes, or from SSOLite to the Background process. Its default value is 50. See Prioritizing Messages for more information.

Notes

Use the SW_UNSET_PRIORITY procedure to restore the default message queue priorities.

Example

The following example sets the SW_CASESTART priority of Case1 and Case2 to 70, Case3 and Case4 to 100, and Case5 to the default priority.

CALL swpro.SW_SET_PRIORITY (70)/
CALL swpro.SW_CASESTART ('CUSTREQ', -1, -1, 'Case1', 'user35', '', ?, ?)/
CALL swpro.SW_CASESTART ('CUSTREQ', -1, -1, 'Case2', 'user35', '', ?, ?)/
CALL swpro.SW_SET_PRIORITY (100)/
CALL swpro.SW_CASESTART ('CUSTREQ', -1, -1, 'Case3', 'user35', '', ?, ?)/
CALL swpro.SW_CASESTART ('CUSTREQ', -1, -1, 'Case4', 'user35', '', ?, ?)/
CALL swpro.SW_UNSET_PRIORITY ()/
CALL swpro.SW_CASESTART ('CUSTREQ', -1, -1, 'Case5', 'user35', '', ?, ?)/
