Starting LLA

The START LLA command is included in the IBM-supplied IEACMD00 member of parmlib. Therefore, the system automatically starts LLA when it reads the IEACMD00 member during system initialization.

Although the system automatically starts LLA, it does not, by default, activate a CSVLLAxx member. To activate a CSVLLAxx member at system initialization, specify the suffix (xx) of the CSVLLAxx member in either of the following places:

In the LLA procedure in SYS1.PROCLIB, as shown, where 'xx' matches the suffix on the CSVLLAxx member to be used:
```
//LLA PROC LLA=xx
//LLA EXEC PGM=CSVLLCRE,PARM='LLA=&LLA'
```
On the START LLA command in the IEACMD00 member, as shown, where 'xx' matches the suffix on the CSVLLAxx member to be used:
```
COM='START LLA,SUB=MSTR,LLA=xx'
```

You should not set a region limit for LLA, either by setting a region size or by an IEFUSI exit. This will avoid storage exhaustion abends in the LLA address space.

If you do not supply a CSVLLAxx member by the LLA=xx parameter of the LLA procedure on the first starting of LLA for this IPL, or if you specify a parameter of LLA=NONE, LLA will by default manage only the libraries that are accessed through the LNKLST concatenation. If you have started LLA successfully with a CSVLLAxx member and then stop LLA, a subsequent start of LLA will use that CSVLLAxx member unless you supply another CSVLLAxx member. If you want to get back to the default settings, specify LLA=NONE.

When started, LLA manages both the libraries specified in the CSVLLAxx member as well as the libraries in the LNKLST concatenation.

If you wish to use something other than the parmlib concatenation for LLA, specify the data set LLA is to use on an //IEFPARM DD statement in the LLA procedure in PROCLIB.
