What is JDK_PATH used for?

[m0002a]

I found a DB2 8.2 (FP8) instance running on AIX 5.2 where the dbm
config JDK_PATH is set to a directory that does not exist. I can't even
find any JDK installed on the server. What does DB2 do with the
JDK_PATH, and under what circumstances is it used by DB2?

It's used for Java UDFs and Java Stored procedures.

It's used for Java UDFs and Java Stored procedures.

And for the DB2 tools (Control Center, First Steps, etc.).

I believe that the DB2 tools (Control Center, First Steps, etc.) use
the JDK_PATH specified in the config for the Administrative Server (get
admin cfg). I was asking about the instance config (dbm cfg), and
answer given by Ian was "Java UDFs and Java Stored procedures."

I understand that Ian gave that answer. And I am quite positive that the
instance config's JDK_PATH is used for the DB2 tools as well since the DB2
tools are part of the adminstration client which does not have an
Administration Server available to use.

The DB2 Administration Server (DAS) is only available on servers - which
also support Java UDFs and Java Stored Procedures, but the DAS JDK_PATH
configuration parm isn't used for that, either. The DAS uses a similar
model to the server for its own behaviour, including stored-procedure-like
functions, which may, themselves, be Java-based. The JDK_PATH parms for
the administration server is used for those functions only.
