OUTPUT command and dynamic allocation of copy data sets

This section discusses the copy data set dynamic allocation options you can code in an OUTPUT statement in your BMC AMI Copy SYSIN data set.

It includes a syntax diagram and provides a description of each option available for disk data sets and for tape data sets.

Default descriptor options are included in the default BMC AMI Copy installation (execution) options module, ACP$OPTS. You can install additional, customized installation options modules, each with its own set of default descriptor options. You select the options module most suitable for your application and departmental needs by coding the option module parameter in your BMC AMI Copy EXEC statement. For more information, see Utility-parameters-on-the-EXEC-statement.

To use the current default output descriptor, use the name DEFAULT in the COPYDDN or RECOVERYDDN option in a COPY or COPY IMAGECOPY statement.

Important

DEFAULT cannot be used for both COPYDDN and RECOVERYDDN when one is specified as stacked to tape and one is not (the UNIT, UNITRP, UNITLB, and UNITRB installation options).

To modify the default descriptor, provide a new descriptor name in an OUTPUT statement and code the options you want to change. Any options not coded default to the corresponding values in the default descriptor. Also, by using the DSNAME, COPYDSN, or RECOVERYDSN option in a COPY or COPY IMAGECOPY statement, you can override the default data set names without using an OUTPUT statement.

For information about requesting dynamic allocation of output copy data sets within a COPY statement, see COPYDDN and RECOVERYDDN. See also FULLDDN, FULLDSN, FULLRECDDN and FULLRECDSN, and their alternatives, BIGDDN, BIGDSN, BIGRECDDN, and BIGRECDSN, beginning on FULLDDN. For information about requesting dynamic allocation within a COPY IMAGECOPY statement, see COPYDDN and RECOVERYDDN.

All statements in the SYSIN data set are processed sequentially, so a new output descriptor named in an OUTPUT statement is available for all COPY or COPY IMAGECOPY statements that follow that OUTPUT statement. You can use more than one OUTPUT statement in an SYSIN data set, but each output descriptor must have a different name.

Important

When you use multiple table space names in a single list, whether explicitly or by wildcard, you must use dynamic allocation.
