Using the dump viewer in batch mode

For long running or routine jobs, jdmpview can be used in batch mode.

You can run a single command without specifying a command file by appending the command to the end of the jdmpview command line. For example:

jdmpview -core mycore.dmp info class

When specifying jdmpview commands that accept a wildcard parameter, you must replace the wildcard symbol with ALL to prevent the shell interpreting the wildcard symbol. For example, in interactive mode, the command info thread * must be specified as:

jdmpview -core mycore.dmp info thread ALL

Batch mode is controlled with the following command line options:

-cmdfile <path to command file>: A file that contains a series of jdmpview commands. These commands are read and run sequentially.; The command file can have empty lines that contain spaces, or comment lines that start with // or #. These lines are ignored by jdmpview.
-charset <character set name>: The character set for the commands specified in -cmdfile.; The character set name must be a supported charset as defined in java.nio.charset.Charset. For example, US-ASCII.
-outfile <path to output file>: The file to record any output generated by commands.
-overwrite: If the file specified in -outfile exists, this option overwrites the file.
-append: If the file specified in -outfile exists, new output messages are appended to the end of that file. The -append and -overwrite options cannot be used at the same time.

Consider a command file, commands.txt with the following entries:

info system
info proc

The jdmpview command can be run in the following way:

jdmpview -outfile out.txt [-overwrite|-append] -cmdfile commands.txt -core <path to core file>

When the output file exists, you need to specify either the -overwrite option or the -append option. If you do not, then an error message is shown.

Output similar to the following is shown in the console and in the output file, out.txt:

DTFJView version 4.29.5, using DTFJ version 1.12.29003
