For the ALLOCATE and DEFINE commands (&ACSENVIR='ALLOC'), the
data class ACS routine and then the storage class ACS routine are
executed. If the storage class is not null, the management class ACS
routine and then the storage group ACS routine are executed.
For the IMPORT command, the storage class ACS routine is executed
first. If the storage class is not null, the management class ACS
routine and then the storage group ACS routine are executed.
The STORCLAS ACS routine is not redriven or invoked on data set
rename. Redriving the MGMTCLAS ACS routine on data set rename invokes
the management class ACS routine when an SMS managed cluster, Generation
Data Set (GDS) or non-VSAM data set is renamed. Catalog management
invokes the MGMTCLAS ACS routines during rename processing. You can
reassign a different management class based on the following data
set attributes:
- New data set name
- Data set type
- Data set organization
- Expiration date in the catalog
- Old management class
- Data class
- Storage class
- Record organization
- User information
- Group information
ACS routines support RENAME. The following read-only variables
are set for the management class ACS routine:
- &ACSENVIR:RENAME
- &DSN of the new data set name
- &DSORG
- &DSTYPE
- &EXPDT
- &STORCLAS
- &DATACLAS
- &MGMTCLAS
- &GROUP of the job
- &USER of the job
- &HLQ
- &LLQ
