IMMEDIATE WRITE field (IMMEDWRI subsystem parameter)

The IMMEDWRI subsystem parameter determines when updates to group buffer pool-dependent buffers are to be written to the coupling facility.

Acceptable values: YES, NO
Default: NO
Update: Start of changeoption 19 on panel DSNTIPBEnd of change
DSNZPxxx: DSN6GRP IMMEDWRI
YES
DB2® immediately writes the page to the coupling facility after the update occurs.
NO
DB2 does not immediately write the change buffer to the coupling facility. Instead, DB2 waits until phase 1 of commit.

If either the IMMEDWRITE bind option or the IMMEDWRI subsystem parameter is set to YES, the value of the immediate write option at run time is also YES.
