NAME¶
jinfo - Generates configuration information. This command is experimental and
unsupported.
SYNOPSIS¶
jinfo [ option ] pid
jinfo [ option ] executable core
jinfo [ option ] [ servier-id ] remote-hostname-or-IP
- option
- The command-line options. See Options.
- pid
- The process ID for which the configuration information is to be printed.
The process must be a Java process. To get a list of Java processes
running on a machine, use the jps(1) command.
- executable
- The Java executable from which the core dump was produced.
- core
- The core file for which the configuration information is to be
printed.
- remote-hostname-or-IP
- The remote debug server hostname or IP address. See
jsadebugd(1).
- server-id
- An optional unique ID to use when multiple debug servers are running on
the same remote host.
DESCRIPTION¶
The jinfo command prints Java configuration information for a specified
Java process or core file or a remote debug server. The configuration
information includes Java system properties and Java Virtual Machine (JVM)
command-line flags. If the specified process is running on a 64-bit JVM, then
you might need to specify the -J-d64 option, for example:
jinfo-J-d64 -sysprops pid.
This utility is unsupported and might not be available in future
releases of the JDK. In Windows Systems where dbgeng.dll is not
present, Debugging Tools For Windows must be installed to have these tools
working. The PATH environment variable should contain the location of
the jvm.dll that is used by the target process or the location from which
the crash dump file was produced. For example, set
PATH=%JDK_HOME%\jre\bin\client;%PATH% .
