Step 4E: Update LNKLSTxx

To run SA z/OS, you must ensure that program libraries can be found at startup time.

Add SINGLOAD (recommended) and SINGLINK (mandatory) to the LNKLST concatenation. There is no other choice for these libraries: they must be in the LNKLST concatenation.

For the other libraries, either add them to the LNKLST concatenation or add them on STEPLIB DDs in the JCL in SYS1.PROCLIB that is used to start the products.

Adding libraries on STEPLIB DDs will involve performance degradation compared to adding them to the LNKLST concatenation and should therefore be avoided.

z/OS link list data sets no longer have to be cataloged in the master catalog. It is possible to specify a volume in the link list entry for data sets that are cataloged in user catalogs.

Edit the LNKLSTxx member to add the following to the LNKLST concatenation: ING.SINGLOAD, ING.SINGLINK.

You can avoid an IPL: You can also code a PROGxx member to add libraries to the LNKLST concatenation. If you do this, no IPL is required. For a complete description of dynamic LSTLNK and PROGxx, see z/OS MVS Initialization and Tuning Reference.
