ActiveMQ 5.10 compatibility with KahaDB
Hi,
I am using ActiveMQ 5.8 and trying to switch to ActiveMQ 5.10. The problem
here is that I have to clear the kahaDB before switch otherwise I get error.
This also happens if I want to switch back from 5.10 to 5.8.
Everytime we need to clear the kahaDB
Error:
"java.io.IOException: Could not load journal record. Invalid location:
1:978"
Thanks,
Anuj

before an upgrade, take a copy/backup of the data directory that can
be used as a fallback.

The source is there, if you'd like to start working on adding in that
sort of support we accept contributions.

But ideally it should be supported.
It may be possible that after switching broker to 5.10, broker or clients
can face some issues. In such scenerios, we revert broker back to 5.8. It
should be backward compatible.
Thanks,

We don't really do version downgrades on the store, going forward should
work fine, going backwards doesn't really make much sense and is not
supported.

Re: ActiveMQ 5.10 compatibility with KahaDB
Posted by khandelwalanuj <kh...@gmail.com>.
Hi Gary,
When i switch my broker from 5.8 to 5.10, everything seems to be normal and
works fine. But when I switch back from 5.10 to 5.8, I am seeing issues.
Below are the details of my configuration:
1. Using MultikahaDB.
Configuration:
* <amq:persistenceAdapter>
<amq:mKahaDB directory="/u/khandela/activemq/kahadb"
journalMaxFileLength="64mb">
<amq:filteredPersistenceAdapters>
<amq:filteredKahaDB queue="flow.>">
<amq:persistenceAdapter>
<amq:kahaDB/>
</amq:persistenceAdapter>
</amq:filteredKahaDB>
<amq:filteredKahaDB queue="gear.>">
<amq:persistenceAdapter>
<amq:kahaDB/>
</amq:persistenceAdapter>
</amq:filteredKahaDB>
<amq:filteredKahaDB>
<amq:persistenceAdapter>
<amq:kahaDB/>
</amq:persistenceAdapter>
</amq:filteredKahaDB>
</amq:filteredPersistenceAdapters>
</amq:mKahaDB>
</amq:persistenceAdapter>
*
Details of my test case:
Started broker with 5.8, stopped and started with 5.10 (works fine) but
again stopped and started broker with 5.8 (Not working). Please note that I
have tested this with two case: (i) clients are conencted (ii) clients are
not connected, and in both the cases the same issue observed.

Re: ActiveMQ 5.10 compatibility with KahaDB

That is not good. We try and do auto updates - the test is at
https://github.com/apache/activemq/blob/trunk/activemq-unit-tests/src/test/java/org/apache/activemq/store/kahadb/KahaDBVersionTest.java
I wonder what is different in your store?
You could just rebuild the index, use forceRecoverIndex on kahaDB for
the first restart after an upgrade and that should work ok.
It would be great if you could modify the exisitng test case we have,
to demonstrate the failure.
