The naming convention for image copy data sets that do
not use the DFSMSdss fast replication function is high-level-qualifier.dbdname.ddname.IC.low-level-qualifier.
- high-level-qualifier
- A character string that can be from 1 to 8 alphanumeric characters long. The first character must be alphabetic.
- dbdname
- The database name of the DBDS for which the image copy data set is being recorded in the RECON data set.
- ddname
- The data set DD name of the DBDS for which the image copy data set is being recorded in the RECON data set.
- IC
- Indicates that this is the image copy data set.
- low-level-qualifier
- A character string that can be from 1 to 8 alphanumeric characters long. It must be unique for each DBDS and the first character must be alphabetic.
The naming convention for image copy data sets that use the DFSMSdss fast replication function can be either of the two following formats:
high-level-qualifier.dbdname.ddname.Dyyddd.Thhmmsshigh-level-qualifier.dbdname.ddname.- high-level-qualifier
- A character string that can be from 1 to 25 alphanumeric characters long. The first character must be alphabetic. The character string may represent multiple data set qualifiers, each from 1 to 8 alphanumeric characters long, separated by a period. The first character of each qualifier must be alphabetic, and the last character of the string must not be a period.
- dbdname
- The DBD name of the database for which the image copy data set is being recorded in the RECON data set.
- ddname
- The data set DD name of the DBDS for which the image copy data set is being recorded in the RECON data set.
