The SAV command provides additional save-while-active options which you specify on the SAVACTOPT parameter. The default is *NONE, which means that no additional options are used during a save-while-active operation.
Applications should only use the allow checkpoint write (*ALWCKPWRT) option to save objects which are associated with the application. Also, the applications should have additional backup and recovery considerations such as Lotus® Domino® databases.
Objects with the QP0L_ATTR_ALWCKPWRT server attribute set will be locked with O_SHARE_RDWR by the save operation. You can update data before the save-while-active operation reaches a checkpoint.
You will need to verify these objects after you restore them. You may also need to perform additional recovery procedures before they are usable.
