RECFM=U data set parameters

These settings pertain only to data sets that have a record format of RECFM=U, have no recognizable create program name, and cannot be identified as ADRDSSU dump files by Tape Optimizer testing.

Usually, Tape Optimizer can determine the appropriate copy utility to use based on its normal testing. (For more information, see How Tape Optimizer selects the copy utility to use.) However, in the unusual situations where Tape Optimizer cannot determine the copy utility to use automatically, the copy utility is determined by the REQU_CALL_ADRDSSU_TSTF parameter (or its default value) and by these optional RECFM=U data-set parameters if defined. These optional parameters pertain to specific data sets and override the utility that is selected by the REQU_CALL_ADRDSSU_TSTF parameter, for the specified data sets only.

To indicate the copy utility to use for a specific data set or a set of data sets, you must specify the REQU_FILT_ADRD_nnnn and the REQU_FILT_ADRF_nnnn parameters. Optionally, you can also specify the REQU_FILT_ADRV_nnnn parameter. A single set of these parameters (for the data set name, utility indicator, and volser) comprise a "RECFM=U data-set specification" and must have parameter names that end in the same nnnn number; this number can be a value from 0001 through 9999. You can define up to 9999 specifications by incrementing the ending nnnn value in the parameter names by one. For example, REQU_FILT_ADRD_0001, REQU_FILT_ADRF_0001, and REQU_FILT_ADRV_0001 comprise the first specification; REQU_FILT_ADRD_0002, REQU_FILT_ADRF_0002, and REQU_FILT_ADRV_0002 comprise the next specification; and so on.

REQU_FILT_ADRD_nnnn=data_set_name

Specifies a fully qualified data set name or a name mask for the RECFM=U data set or data sets for which you want to specify the copy utility (that is, for which you want to override the REQU_CALL_ADRDSSU_TSTF setting). This value can be up 44 characters in length. To specify a mask, type the first few characters of a data set name followed by the asterisk (*) wildcard, for example, PAYROLL.*. Tape Optimizer matches the mask against the input data set names to determine which data sets to copy with the specified copy utility.

REQU_FILT_ADRF_nnnn=Y|N

Indicate whether to use the ADRDSSU utility to copy the specified data set or data sets. Specify Y to use the ADRDSSU utility, or specify N to use IEBGENER instead.

REQU_FILT_ADRV_nnnn=volser

Specifies the volser value of the tape volume on which the specified data set or data sets reside. If you do not specify the volser, the copy utility that is indicated by the REQU_FILT_ADRF_nnnn parameter will apply to all data sets on the input tapes that match the specified data set name or name mask.

These parameters correspond to the columns on the RECFM=U Specifications panel for a copy request (GTOP02U) in the Tape Optimizer interface.
