Log and trace file names
The base log and trace file names in runtime.properties are used
as templates to generate unique sets of log and trace files for each
application server. The default base trace file name is trace.txt; the default base log file name is messages.txt. The application server name is appended
to the base file name to generate the template for the log and trace
files for an application server. The application
server name is the same as the fully qualified name
of the application server, as defined by WebSphere®. This name is cell_node_server,
where:
- cell is the name of the WebSphere® cell.
- node is the name of the WebSphere® node.
- server is the name of the WebSphere® server.
Using the trace file as an example, the name becomes trace _cell_node_server_.txt. Finally, an index
(1, 2, 3, and so on) is added to this name to distinguish multiple
files. With multiple trace files configured, the trace file names
for this application server are trace_cell_node_server_1.txt,
trace_cell_node_server_2.txt, and so on.
Note: When
running on WebSphere® Application
Server for z/OS®, an application
server can have more than one Servant running, with each Servant generating
unique log and trace files. To distinguish these, the server component
of the name is prefixed with the Address Space ID (ASID) of the Servant
(example: trace_asid_1.txt).
