Whoever works with mainframes knows that to be able to o know what the Linklist concatenation is is one of the most important things in the job.

There is a very simple MVS command for the effect:

D PROG,LNKLST

Here’s an example of what this command returns:

RESPONSE=TST1
CSV470I 12.29.52 LNKLST DISPLAY 888
LNKLST SET LNKLST01 LNKAUTH=LNKLST
ENTRY  APF  VOLUME  DSNAME
1       A TST1R1 SYS2.LINKLIB
2       A TST1R1 SYS1.MIGLIB
3       A TST1R1 SYS1.CSSLIB
4       A TST1R1 SYS2.LINKLIB
5       A TST1R1 SYS1.LINKLIB
6 TST1R1 SYS1.SORTLIB
...

Explanation:

TST1 is the LPAR name

LNKLST01 indicates the Linklist set currently active and in use by the system

A indicates that the dataset is also in APF list

TST1R1 indicates the volume where the dataset is allocated

Note:

The Linklist concatenation is defined in the PROGxx member of the PARMLIB.
