Javadump tags

The Javadump file contains sections separated by eyecatcher title areas to aid readability of the Javadump.

The first such eyecatcher is shown as follows:

NULL           ------------------------------------------------------------------------
0SECTION       ENVINFO subcomponent dump routine
NULL           =================================

Different sections contain different tags, which make the file easier to parse for performing simple analysis.

You can also use DTFJ to parse a Javadump, see Using the Diagnostic Tool Framework for Java for more information.

An example tag (1CIJAVAVERSION) is shown as follows:

1CIJAVAVERSION J2RE 6.0 IBM J9 2.5 AIX ppc-32 build jvmap32srt60sr2-20090513_35395

Normal tags have these characteristics:

Special tags have these characteristics:

Here is an example of some tags taken from the start of a dump. The components are highlighted for clarification.

For the rest of the topics in this section, the tags are removed to aid readability.
