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:
Here’s an example of what this command returns:
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
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
The Linklist concatenation is defined in the PROGxx member of the PARMLIB.
