How to bypass dataset maintenance in Workload Automation Restart Option for z/OS Schedulers?
CA 11 will perform dataset maintenance for any dataset with DISP of NEW or when no DISP is specified which defaults to NEW,DELETE,DELETE.
CA 11 provides facilities to help ensure that data sets which should never be deleted are exempt from normal CA 11 uncatalog/scratch functions. The following facilities are available:
? Reserved Data Set Exit (U11RDSEX)
? Uncatalog/Scratch Exit (U11UCSEX)
? Volume Include/Exclude List
User exit U11RDSEX (Reserve Dataset Exit) can be coded to indicate to CA 11 not to perform dataset maintenance to the datasets specified in the exit. Any dataset name specified will not have dataset maintenance done to it by CA 11. User exit U11UCSEX (Uncatalog/Scratch Exit) allows you to exempt a data set from CA 11 uncatalog functions, scratch functions, or both. The Volume Include/Exclude List allows you to exempt entire DASD volumes from CA 11 uncatalog functions, scratch functions, or both.
For more information on U11RDSEX and U11UCSEX please see the CA 11 Programmer Guide in Chapter 3: User Exits. For more information on the Volume Include/Exclude list please see section entitled ‘U11VOLCX—Volume Include/Exclude List’ in the CA 11 Programmer Guide.
