The following trace options allow you to capture the information
needed to detect problems.
To view or set these options, use the WebSphere® Application
Server administrative console:
- Select .
- Specify the variable name in the name field and specify the setting
in the value field. You can also describe the setting in the description
field on this tab.
- ras_trace_outputLocation=SYSPRINT | BUFFER | TRCFILE
- Specifies where you want trace records to be sent:
- To SYSPRINT
- To a memory buffer (BUFFER), the contents of which are later
written to a CTRACE data set
- To a trace data set (TRCFILE) specified on the TRCFILE
DD statement in the start procedure for the server.
For servers, you can specify one or more values, separated by
a space. For clients, you can only specify SYSPRINT. Defaults:
- For clients, SYSPRINT
- For all other processes, BUFFER
Example: ras_trace_outputLocation=SYSPRINT
BUFFER
- ras_time_local=0 | 1
- Specifies whether timestamps in trace records use Greenwich Mean
Time (GMT) or local time. This variable setting controls timestamp
format in the error log, and in traces sent to SYSPRINT or TRCFILE
DD.
Default: 0 (GMT)
Example: ras_time_local=1
sets timestamps to local time.
- Daemon_ras_trace_ctraceParms=SUFFIX | MEMBER_NAME
- Identifies the CTRACE PARMLIB member. The value can be either:
- A two-character suffix, which is added to the string CTIBBO
to form the name of the PARMLIB member, or
- The fully specified name of the PARMLIB member. A fully specified
name must conform to the naming requirements for a CTRACE PARMLIB
member.
If this environment variable is specified and the PARMLIB member
is not found, the default PARMLIB member, CTIBBO00, is used. If neither
the specified nor the default PARMLIB member is found, tracing is
defined to CTRACE, but there is no connection to a CTRACE external
writer. Note: The Daemon is the
only server that recognizes this environment variable.
Default:
00 (the default PARMLIB member, CTIBBO00)
Example: Daemon_ras_trace_ctraceParms=01
identifies PARMLIB member CTIBBO01
- ras_trace_BufferCount= n
- Specifies the number of trace buffers to allocate. Valid values
are 4 through 8.
Default: 4
Example: ras_trace_BufferCount=6
- ras_trace_BufferSize= n
- Specifies the size of a single trace buffer in bytes. You can
use the letters K (for kilobytes) or M (for megabytes). Valid values
are 128K through 4M.
Default: 1M
Example: ras_trace_BufferSize=2M
