Synchronization-level values for Save Active (SAVACT) parameter

This table shows which synchronization levels are available for each command and the value to specify for each level.

Table 1. SAVACT parameter values
Command	Full Synchronization	Library Synchronization	System-Defined Synchronization
SAVLIB SAVOBJ SAVCHGOBJ	*SYNCLIB	*LIB	*SYSDFN
SAVRSTLIB, SAVRSTOBJ SAVRSTCHG	not available	*LIB	*SYSDFN
SAVDLO SAVRSTDLO	not available	not available	*YES
SAV SAVRST	*SYNC	not available	*YES

Full synchronization
All objects you are saving reach a checkpoint at the same time. The system then saves them to the media. IBM^® strongly recommends that you use full synchronization, even when you are saving objects in only one library.
Library synchronization
All objects in a library reach a checkpoint at the same time. But different libraries reach checkpoints at different times. This option may be useful if all of the following are true.
System-defined synchronization
Using this option could cause lengthy recovery procedures. You should only use this option for objects that you are protecting with journaling or commitment control to avoid extremely complex recovery procedures.
