5.2 Application Server Log
This section describes how to investigate Application Server log.
By investigating message logs and user logs of Application Server, you can investigate the cause of error occurrence. Moreover,
even in the case of process errors, you can confirm the progress status of the process and error indications.
Furthermore, among Application Server logs, for the precautions when referencing a system log of the EJB client applications,
see 2.6.1 Precautions Related to the System Log of an EJB Client Application.
The Application Server log includes the following three types of logs:
The trace common library format is the log that is output by using the trace common library. For details on the trace common
library format, see 8.2.2 Mechanism of the user log output in the uCosminexus Application Server Expansion Guide.
The specific format is the log that is output in a format other than the trace common library format.
This section classifies and describes the Application Server log for each log type. The following Application Server log is
described here:
Note that the time-based switching of output destinations and file naming in Shift mode might be enabled in the Hitachi Trace
Common Library format log. For details, see 3.2.1 Specifiable contents.
The following table describes the logs that are output, the corresponding log types, and whether time-specified switching
and shift mode are supported, for each acquired log.
