Starting the library lookaside (LLA) address space

Use the START LLA command to start the LLA address space.
 
S LLA[,SUB=MSTR][,REUSASID=YES][,LLA=xx]
 

The parameters are:

LLA
Invokes the LLA procedure and creates the LLA address space.

The START LLA command is initially issued by the system from the logical parmlib member IEACMD00. Use this command if LLA stops, either because of an error or as a result of a STOP LLA command.

SUB=MSTR
Indicates that the master subsystem will process the task. If you omit this parameter, the system issues message CSV209I indicating that the request to start LLA is ended and the system re-issues the command with SUB=MSTR.
REUSASID=YES
Indicates that a reusable ASID should be assigned to the LLA address space.
LLA=xx
Indicates which CSVLLAnn parmlib member LLA is to use. 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 in a subsequent start of LLA.
Note:
  1. System performance is degraded if LLA stops.
  2. LLA provides better performance when VLF services are available, so it is better (although not necessary) to start VLF before starting LLA. However, the operation of LLA does not depend upon VLF.
  3. Place the S LLA and S VLF commands in either the IEACMD00 or COMMANDxx members of the logical parmlib data set.
  4. If F LLA, UPDATE=xx command is done in between start and stop, the update is not honored by the restarted LLA which is brought up without specifying LLA=xx.
