.Dt JAVAVM_OPTS.CONF 5
|
|
.Sh NAME
|
|
.Nm javavm_opts.conf
|
|
.Nd the Java VM wrapper options configuration file.
|
|
.Sh DESCRIPTION
|
|
The file
|
|
.Nm
|
|
contains variables which set options that should be passed to the
|
|
Java VM that is invoked by the Java VM wrapper.
|
|
.Pp
|
|
Which Java VM a variable provides options for is determined by the variable
|
|
name. The Java VM wrapper currently recognises the following patterns for
|
|
variable names:
|
|
.Bl -tag -width indent
|
|
.It Ev JAVAVM_OPTS
|
|
The options specified by this variable are passed to all Java VM
|
|
invocations. In practise, this variable should be reserved for use
|
|
on the command line and not set in
|
|
.Nm .
|
|
.It Ev JAVAVM_OPTS_JAVA_HOME_DIR
|
|
The contents of this variable are passed as options to all java
|
|
commands invoked by javavm within the
|
|
.Pa JAVA_HOME_DIR
|
|
directory specified.
|
|
The
|
|
.Pa JAVA_HOME_DIR
|
|
specified here is the directory portion of
|
|
.Ev JAVA_HOME
|
|
with special characters replaced by an underscore.
|
|
.It Ev JAVAVM_OPTS_JAVA_PROG
|
|
The contents of this variable are passed as options to all invocations
|
|
of the specified java programme.
|
|
.It Ev JAVAVM_OPTS_JAVA_HOME_DIR_JAVA_PROG
|
|
The contents of this variable are passed as options to the invocation
|
|
of the specified java programme within the specified JAVA_HOME
|
|
directory.
|
|
This allows the options to only affect a single programme.
|
|
.El
|
|
.Sh FILES
|
|
.Bl -tag -width indent
|
|
.It Pa %%PREFIX%%/etc/javavm_opts.conf
|
|
The location of the Java VM wrapper options configuration file.
|
|
.It Pa %%PREFIX%%/etc/javavm_opts.conf.dist
|
|
The location of the example Java VM wrapper options configuration file
|
|
distributed with the Java VM wrapper.
|
|
.El
|
|
.Sh EXAMPLES
|
|
.Bl -tag -width indent
|
|
.It Ev JAVAVM_OPTS_diablo_jdk1_5_0=-XX:+UseMembar
|
|
Run the Java VMs installed by the Diablo JDK in
|
|
.Pa %%PREFIX%%/diablo-jdk1.5.0
|
|
with the option
|
|
.Dq -XX:+UseMembar .
|
|
.It Ev JAVAVM_OPTS_javac=-deprecation
|
|
Run the
|
|
.Pa javac
|
|
programme with the option
|
|
.Dq -deprecation .
|
|
.It Ev JAVAVM_OPTS_diablo_jdk1_5_0_javac=-Xlint
|
|
Run the javac installed by the Diablo JDK with the option
|
|
.Dq -Xlint .
|
|
.El
|
|
.Pp
|
|
Due to stacking, if the above three variables were set, then the javac
|
|
installed by the Diablo JDK would run with the options
|
|
.Dq -XX:+UseMembar -deprecation -Xlint
|
|
(although not necessarily in that order).
