Dynamically allocate unload data sets using IBM UNLOAD

On the Analysis Utility Dataset Options panel (see Dynamically-allocate-unload-data-sets-using-UNLOAD-PLUS), you can select to use the dynamically allocated data sets and to override any JCL Generation options that apply to dynamic allocation.

When you select to use UNLOAD, LOAD, and Use Dynamic SYSRE datasets, the product uses the utilities and inserts the DYNUNLD keyword into the ALUIN input stream. When you select Override Defaults for Dynamic Allocation, the JCL Generation Main Menu is displayed. You can select Tape Options (see Setting-the-JCL-options-for-tapes) and Individual Data Set Options (see Setting-the-JCL-options-for-permanent-data-sets) to override the options that relate to dynamic allocation.

Considerations for dynamically allocating data sets

Consider the following items when you choose to dynamically allocate the unload data sets:

• You cannot stack the unload (SYSREC) data sets on a tape.
• If the IBM UNLOAD utility fails while unloading the data, you must manually delete the appropriate unload (SYSREC) data sets before restarting the worklist. IBM UNLOAD does not automatically delete the dynamically allocated data sets.
• When using spanned records, you must specify dynamic allocation of unload data sets (SYSRECS). Specify the Use Dynamic SYSRE datasets option.
