7.3.1 -XX:[+|-]HitachiThreadDump

-XX:[+|-]HitachiThreadDump outputs extended thread dump information.

Description

-XX:[+|-]HitachiThreadDump specifies whether to output extended thread dump information.

Thread dumps are output to the standard output and to the file below.

Thread dump output destination

By default, the output destination is the current directory during Java VM execution. However, you can change the output destination by specifying the environment variable JAVACOREDIR.

Thread dump output file name

javacoreprocess_number.YYMMDDhhmmss^#.txt

#:

YY: year (last 2 digits), MM: month (2 digits), DD: date (2 digits)

hh: hour (24-hour notation), mm: minute (2 digits), ss: second (2 digits)

The table below shows the structure of the thread dump information.

Table 7‒1: Structure of the thread dump information

---------------
JNI global references:  number_of_JNI_global_references

The following provides details about the output:

Output item	Output content
`number_of_JNI_global_references`	The number of global references that are allocated to Java VM is output.

Note: Because JNI global references are also reused in Java VM, the number of references does not decrease even when a JNI global reference is deleted by issuing the DeleteGlobalRef function that is supported by JNI. Similarly, when JNI global references that are reused by Java VM are assigned, the number of references does not increase even if a new JNI global reference is created by issuing the NewGlobalRef function.

Explicit heap information and Explicit memory block information

Explicit Heap Status
--------------------
 max EH_MAX, total EH_TOTAL, used EH_USED, garbage EH_GARB (EH_PER1 used/max, \
EH_PER2 used/total, EH_PER3 garbage/used), EM_NUMS spaces exist
 
 Explicit Memories(EM_MGR_PTR)
  
  ""EM_NAME"" eid=EID(EM_PTR)/EM_TYPE, total EM_TOTAL, \
used EM_USED, garbage EM_GARB (EM_PER1 used/total, EM_PER2 garbage/used, \
FL_BLOCKS blocks) EM_STAT

                   ...
                  AISIZE      AINUM total

...

Note the following:

There is a blank row between the Explicit heap information and the Explicit memory block information.
The order in which the Explicit memory block information is to be output (the Explicit memory block from which output is to start) is not defined.
There are two single-byte spaces before EM_NAME.
There are four single-byte spaces before deployed objects.
ISIZE is output so that the last character of this character string is aligned with the "e" of _________________Size_.
INUM is output so that the last character of this character string is aligned with the last "s" of __Instances.
FRATIO is output so that the last character of this character string is aligned with the "o" of __FreeRatio__.
CNAME is output so that the first character of this character string is aligned with the second ""_"" from the beginning of __Class________________ (the underscore directly before the "C").
The last row is blank. As a result, there is a blank row between each pair of Explicit memory blocks that are output.
