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: | option 19 on panel DSNTIPB |
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.
