AGW START

Purpose

Use the AGW START command to start AVS and to enable external tracing. (Internal tracing is always enabled during AVS initialization.)

Operands

40
reserves 40 1KB blocks of virtual storage for the AVS internal trace table; this is the default.
nnnn
is the number of 1KB blocks of virtual storage that the AVS internal trace table uses. You may specify an nnnn value between 1 and 1000; if nnnn is not divisible by 4, AVS rounds up the value to the next 4K boundary.
ETRACE
enables external tracing. AVS externally writes certain AVS trace records to a TRSOURCE spool file. You must specify this parameter to get an external trace during AVS initialization.

If you do not specify ETRACE, external tracing is off and AVS writes trace records only to the AVS internal trace table, which is with the AVS virtual machine's virtual storage, until an AGW SET ITRACE OFF command is entered.

See the AGW SET ETRACE command (see Purpose) for the requirements that must be met before external tracing is in effect.

What Happens When You Enter this Command

After AGW START has completed, AVS is initialized and is ready to work. If there is an AGWPROF GCS exec (see Creating the AGWPROF GCS Exec), all of the commands contained in it will run. When the command completes, AVS issues the following message: 
AGWINI001I AVS initialization is complete. The service level is nnnn.

After AVS initializes, you can disable internal tracing by entering the AGW SET ITRACE OFF command (described in Purpose).
