2 2 Java Service Manager Administration for Windows

2.2 Java Service Manager Administration for Windows

The Java Service Manager Administration on Windows is a service application.

How To Start

On Windows, if the JSM service's Start-up Type is set to Automatic, Microsoft Service Control Manager will start the service automatically during system startup. If it is set to Manual, you need to use Microsoft Service Control Manager to start the JSM Administrator.

JSM Administrator starts the Java Virtual Machine and launches the Java Service Manager. If the administrator program has performed an upgrade, then the JSM will have stopped.

If the administrator program has stopped due to an upgrade, start the JSM Administrator again.

To stop the JSM server from ending when the user logs off, the JVM option -Xrs needs to be present.

Program Options

The JSM Administrator configuration options are specified in the jsmmgrdta.txt file.

Priority	The JVM process priority. Possible values are LOW, HIGH, NORMAL, BELOWNORMAL or ABOVENORMAL. Default is NORMAL.
Instance	The path of the instance. Default is ..\JSMInstance.
JVM	The path of the Java program to execute. To specify another JRE or JDK use the absolute path to the java program. For example: C:\Program Files\Java\jdk1.5.0_22\bin\java Default is java.
JVMOptions	The Java program options. There is no default value. The shipped value is -Xms128M -Xmx128M -Xrs -Djava.endorsed.dirs=.\endorsed

 

JSM is only compatible with a 32-bit JRE or JDK. Even if the JSM Administrator is running on 64-bit Windows it still requires a 32-bit JRE or JDK to be installed.

Clear Trace

Clear Trace removes files and subdirectories in the trace and/or temp directories.

It can be run in interactive mode or as a batch job. The path of the instance is taken from the jsmmgrdta.txt file (see Program Options for the Java Service Manager Administration for Windows).

Clear Trace can be run from the Start | Programs | Menu or from the command line. You can use any of the following three options, all of which are optional.

/batch
Run Clear Trace as a batch job

/temp
Remove files and subdirectories in the temp directory only.

/trace
Remove files and subdirectories in the trace directory only.

Interactive mode Example:

From the Clear Instance dialog, select the actions you wish Clear Trace to take:

This will result in:

clrjsm to remove trace and temp files (default behavior)
clrjsm /trace /temp to remove trace and temp files
clrjsm /temp to remove temp files and not trace files
clrjsm /trace to remove trace files and not temp files.

Batch mode Examples:

clrjsm/batch removes trace and temp files
clrjsm /batch /trace /temp removes trace and temp files
clrjsm /batch /temp removes temp files and not trace files
clrjsm /batch /trace removes trace files and not temp files.
