The CA 1 Scratch Pool Management feature allows you to protect defined ranges of tapes in the TMC by restricting nonspecific output access based on data set name, SMS Management Class name, creating job name, creating unit name, expiration date, temporary file status, or by specifying the pool name in the JCL.
Many applications require the use of tapes with specific physical characteristics, such as tape length, quality of tape, reel size, type of container, and so forth. Such requirements may be imposed by government agencies or internal business procedures or simply for operating convenience. The multiple scratch pool management capabilities of CA 1 provide the necessary support to satisfy these requirements in a fully automated manner.
Each scratch pool may optionally be defined as a subpool that allows realtime stacking. While file stacking is common, realtime stacking is different. With realtime stacking there is little control over what file sequence number or which volume within the scratch subpool the file will be added.
Note: Apart from READONLYnnnn subpooling, CA 1 does not support scratch subpooling in an OAM managed robotic environment.
