In an emergency (for example, if you cannot access your RACF® database) you can allow the operator to specify data set names and still have the benefit of using a data set name table. One suggested method:

1. Create two load libraries, for example, SYS1.ICHRDSNT.NORMAL and SYS1.ICHRDSNT.EMRGNCY.
2. Put your production ICHRDSNT module in SYS1.ICHRDSNT.NORMAL.
3. Put an emergency ICHRDSNT module in SYS1.ICHRDSNT.EMRGNCY.

   It should be identical with your production ICHRDSNT module except that it should have an asterisk (*) for each data set name.

4. Create two LNKLSTxx members in SYS1.PARMLIB, for example, 00 (normal) and EM (emergency).
5. Put SYS1.ICHRDSNT.NORMAL at the end of 00, and SYS1.ICHRDSNT.EMRGNCY at the end of EM.

With this procedure, for a normal IPL, the operator is not prompted. However, in an emergency, specifying LNKLST=EM during IPL allows the operator to enter the data set names to be used.
