Ensure Availability of a System Linkage Index

CA OPS/MVS requires a system linkage index (LX) in the system function table. If CA OPS/MVS terminates normally or abnormally and you restart it, it reuses this system linkage index. If you plan to run multiple copies of CA OPS/MVS, then you need a system linkage index for each copy.

Typically, the system linkage index should contain enough entries to accommodate CA OPS/MVS. If it does not, then increase the number by modifying the NSYSLX value in the appropriate IEASYSxx member of the Logical Parmlib Concatenation.

Note: You can determine whether the system linkage index contains enough entries to accommodate CA OPS/MVS if you are running CA SYSVIEW product. For information about how you can do this, see the LXATABLE command in the CA SYSVIEW command help. Conversely, without CA SYSVIEW, you cannot determine whether such a condition exists before CA OPS/MVS startup because the z/OS operating system does not provide the capability to check for this data.

For more information about the system linkage index, see the IBM documentation.
