Browse BDB JE Store
Hi,
Does anyone know of any utility that can be used to browse the BDB
datastore?
I'm specifically looking for a tool that will let me inspect a .je file and
display all the databases, key - value pairs present in the file.
I looked at the JMX plugin and the Jconsole plugin that BDB ships with BDB
JE but i wasn't lucky to see any inspect tools in it.
I found the msTool script pretty cool, it works to the effect of what I
need, but is limited that it can't work alongside when the broker is up and
running.
Is there an alternate way to attain what I'm looking for?
Thank you,

Hi Praveen,
It actually possible to tell using the JMX console, you just have to
look at individual messages first by clicking on them in the list in
order to see it in the properties listed for them.

Hi Robbie,
That helped a lot. Thank you. I played around with the JMX console and it's
good for my use cases.
Yep like you mentioned it will be great to have a flag which denotes if a
message is transient/persistant on the JMX console.
Thank you,
Praveen

Hi Praveen,
Im not aware of tools which let you inspect .je files directly in a
nice way, only ones which dump the contents, although I have never
really looked for such tools so they may exist but again probably
wouldnt work while the broker was running.
The method of inspecting the broker while running is currently via its
JMX interfaces, which will give you access to all the queues etc and
can identify whether queues are durable, messages are persistent etc.
You can do this via any generic tool such as JConsole, or via our JMX
management console (available on download page, user guide at
https://cwiki.apache.org/qpid/qpid-jmx-management-console-user-guide.html
) which you should find useful if you liked the msTool (which has
actually just been removed from trunk because it doesnt really offer
much the other ways dont and wasnt being maintained or really usedl;
in fact you are the only person ive ever seen mention it). The only
limitation would be that if you are mixing transient and persistent
messaging it isnt as clear without inspection which is which while the
broker is running (as obviously the transient stuff cases to exist if
you shut it down). Its a running theme to my replies at the moment,
but improved management is also something we intend to look at next
year.
