Subject [jira] Commented: (DERBY-3552) Handle jar files that are installed when replication is enabled
Date Mon, 31 Mar 2008 04:32:24 GMT

V.Narayanan commented on DERBY-3552:
------------------------------------

Thank you for looking at this issue Kim. I apologize for my late reply.

Here is my opinion on what needs to be done

We can retain this line

"If you install jar files on the master system while replication is running, the same jars
are not automatically installed on the slave."

We could rephrase this line

"To ensure that the jars are installed correctly on both systems, you need to force a failover,
then install the jars on the slave system (using either sqlj.remove_jar followed by sqlj.install_jar,
or sqlj.replace_jar)"

to

"To ensure that the jars are installed correctly on both systems, after a failover, install
the jars on the slave system (using either sqlj.remove_jar followed by sqlj.install_jar, or
sqlj.replace_jar)"

So I please request that the paragraph above could be

"If you install jar files on the master system while replication is running, the same jars
are not automatically installed on the slave.
 To ensure that the jars are installed correctly on both systems, after a failover, install
the jars on the slave system (using either sqlj.remove_jar
 followed by sqlj.install_jar, or sqlj.replace_jar)"
---------------------------------------------------------------------------------------------------------------

I suggested the above because

Doing a failover just to install jars on the slave in the middle of transactions with the
initial set of steps that we have recommended
and doing it in reverse again from the slave to the master would be cumbersome to the user.

thanks once again for the follow up on this issue
