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 the specified PARMLIB member is not 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:
None
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
- ras_trace_log_version= n
- Specifies the version of trace log to display. Valid values
are 1 and 2.
Default: 2
Example: ras_trace_log_version=1
