The trace and log messages of the Java Startup Framework contain important information about the status of the Java instance. In case of errors, check and analyze these messages.
The developer trace and log files are located in the /usr/sap/SID/inst_name/work directory, where SID is the system ID of the cluster (for example, C11) and inst_name is the instance name of the instance (for example, DVEBMGS00 or JC01).
The following trace files provide useful information in case of errors.
This is the trace file of the Java instance controller.
Recommendation
We recommend that you always check the end of this file for error messages regarding the startup of the AS Java instance.
The trace file of the corresponding JSTART server process (the <component name> can be deployment, bootstrap, server<n>, or icm). For example, the trace file for the bootstrap process is dev_bootstrap.
The standard and error output file of the corresponding JSTART server process (the <component name> can be deployment, bootstrap, server<n>, or icm).
For example, the output file for the offline deployment process is std_deployment.out. Output and error messages from the Java VM are written to this file.
The standard and error output file of the JVM running the corresponding JSTART server process (the <component name> can be deployment, bootstrap, or server<n>).
For example, the output file for the JVM running the bootstrap process is jvm_bootstrap.out.
