Quiet_Point Noquiet_Point Specifies whether the quiet-point lock will be acquired when an .aij backup operation is performed. The default is the Quiet_ Point qualifier. Use of the Quiet_Point qualifier is meaningful only for a full backup operation; that is, a backup operation that makes a complete pass through all .aij files ready for backup as opposed to one which is done by-sequence (specified with the Sequence qualifier). A full .aij backup operation can be performed regardless of whether an extensible or a fixed-size .aij journaling mechanism is being employed. Each .aij backup operation is assigned an .aij sequence number. This labeling distinguishes each .aij backup file from previous .aij backup files. During a recovery operation, it is important to apply the .aij backup files in the proper sequence. The RMU Recover command checks the database root file structure and displays a message telling you the .aij sequence number with which to begin the recovery operation. The quiet point is a state where all write transactions have either been committed or rolled back and no read/write transactions are in progress. This ensures that the recording of transactions do not extend into a subsequent .aij backup file. This backup file can then be used to produce a recovered database that is in the same state as when the quiet point was reached. When fixed-size journaling is employed, the Quiet_Point qualifier is only relevant when the active .aij file is being backed up. In this case, a quiet point is acquired only once, regardless of the number of .aij files being backed up. There is no natural quiet point if someone is writing or waiting to write to the database at any given time. (A natural quiet point is one that is not instigated by the use of the QP (quiet point) Lock.) The .aij backup operation may never be able to capture a state that does not have uncommitted data in the database. As a result, the Noquiet_Point qualifier creates .aij backup files that are not independent of one another. If you apply one .aij backup file to the database without applying the next .aij backup file in sequence, the recovery operation will not be applied completely. See the Usage_Notes help entry under this command for recommendations on using the Quiet_Point and Noquiet_Point qualifiers. The following combination of qualifiers on the same command line are invalid: o Quiet_Point and Sequence o Quiet_Point and Wait o Noquiet_Point and Format=New
