The HotSpot Serviceability Agent (SA) is a debugger for hotspot core
dumps and hung processes. There is a read-only JDI (Java Debugger
Interface) implementation on top of SA. This is part of JDK product and
the classes are in $JDK/tools/sa-jdi.jar.
In addition, there are few serviceability tools in $JDK/bin, namely,
jstack (java stack trace tool), jmap (heap tool), jinfo (Java config
tool) and jsadebugd. The classes for these are also in sa-jdi.jar
file. sa-jdi.jar file is built along with hotspot (libjvm.so) on Solaris
and Linux platforms. On Windows platform, SA-JDI is not included and
serviceability tools do not use SA.
Apart from these, HotSpot SA consists of a number of tools that are
*not* included in JDK product bits.
The sources and makefile for all-of-SA (including non-productized stuff)
are under $HOTSPOT_WS/agent directory. The makefile $HOTSPOT/agent/make
directory and shell scripts (and batch files) are used to build and run
SA non-product tools. There is also documentation of SA under
$HOTSPOT/agent/doc directory.
To build complete SA, you need to have Rhino Mozilla jar (js.jar)
version 1.5R5 under $HOTSPOT/agent/src/share/lib directory. Rhino is
JavaScript interpreter written in Java. Rhino is used to implement SA
features such as
* SA command line debugger's JavaScript interface
- refer to $HOTSPOT/agent/doc/clhsdb.html
- refer to $HOTSPOT/agent/doc/jsdb.html
* SA simple object query language (SOQL)
- language to query Java heap.
Rhino's "js.jar" is not included in hotspot source bundles. You need to
download it from http://www.mozilla.org/rhino/download.html.
Without js.jar, $HOTSPOT/agent/make/Makefile will fail to build. But,
note that sa-jdi.jar containing the productized portions of SA will
still be built when you build hotspot JVM.
