The CHANGE command is provided to reset the CA Disk expiration date for a specific data set.
The CHANGE data set index command syntax is:
CHANGE DSNAME=,VERSION=,EXPDT=,F1EXPDT,TIMEDATE=,MGMTCL=
STORCL=,DATACL=,DEFAULTMC,PRIMARY2,FAST=
The explicit name of the data set for which the CA Disk expiration date is to be changed.
To change the expiration date of an older version of the dataset, specify -1 to -99 to indicate successively older versions of the dataset (-99 is the oldest version). By default, the most recent version of the dataset is changed.
The date in an accepted CA Disk format that is to be the new CA Disk expiration date for this archived data set.
The date in an accepted CA Disk format that is to be the new Format 1 DSCB expiration date for this archived data set.
Note: RESTORE/RECOVER will use this as the new Expiration Date, provided it does not violate any of the SMS Retention Period Attributes and the DSS path is not being used.
This optional parameter can be used to provide the specific time and date of the DSNINDEX entry to be changed. The format is HHMMYYDDD or HHMMYYYYDDD.
This optional parameter must be specified when the current MGMTCL field is blank and the SMS default management class is to be used for expiring of the DSNINDEX record. No EXPDT= parameter is required.
This optional parameter provides a way to specify a new SMS Management Class name. There are two ways of using this parameter:
To change or nullify (blank out) the Management Class. If you want to nullify the Management Class name, specify <>. However, when using this value either EXPDT= or DEFAULTMC must also be specified on the CHANGE command.
This ensures that the correct expdt will be specified in the DSNINDEX record, either 1999365 for SMS-managed data sets or a true retpd value for nonsms-managed data sets.
Also, when MGMTCL=<> and EXPDT= parameters are used together, the SMS bypass indicator DSNMCBYP is activated.
It provides a Management Class name, which will be validated by the SMS subsystem prior to use. The SMS bypass indicator DSNMCBYP will be turned off when the MGMTCL field is changed and is no longer blank.
This optional parameter provides new SMS Storage Class information. To nullify (blank out) the Storage Class, specify a value of <>. To change the name of the Storage Class, specify a non-blank value. However, when using this value the EXPDT= must also be specified on the CHANGE command.
Note: CA Disk recognizes blank Storage Classes as Non-SMS data sets.
This optional parameter provides new SMS Data Class information. To nullify (blank out) the Data Class, specify <>. To change the name of the Data Class, specify a non-blank value.
This optional parameter indicates that only the PRIMARY2 data set index records are to be changed. By default, only PRIMARY1 data set index records are changed.
This optional parameter allows the Fast Archive status of the data set to be changed. The value can be either YES or NO. Setting the value to YES will automatically set the Fast Archive status to YES on the associated Archive data sets.
