Enabling internal trace for the AMSM address space
Trace for the AMSM address space can be enabled using the _AMS_MSG_LEVEL variable, which is passed into the AMSM address space through the ENVARS DD card.
A sample data set for the ENVARS DD card is in thlqual.SCSQPROC(CSQ40ENV).
Trace is written to the SYSOUT of the AMSM address space.
The _AMS_MSG_LEVEL variable specifies the subcomponent and message level that is to be logged. An asterisk indicates all subcomponents to be logged; currently there is only one subcomponent.
The severity levels are:
- S - severe messages only
- E - error and severe messages only
- W - warning, error, and severe messages only
- I - informational, warning, error, and severe messages. This is the default value
- D - debug mode, all messages with additional debug diagnostics
- V - verbose mode, all of the preceding, plus buffer dumpsAttention: You should only enable debug or verbose mode on the advice of an IBM® service representative.
For example, to enable the default for _AMS_MSG_LEVEL, issue the
following:
_AMS_MSG_LEVEL=*.i
To enable verbose mode, issue the following:
_AMS_MSG_LEVEL=*.v
