Re: [xmlblaster] client stops receiving messages

Hi Marshal,

I'm sorry, I didn't realize there was an embedded database. Instead, I
thought if I hadn't configured a database, you saved things in files. My
mistake. So, yes I am using the default embedded database.

As a side question to my larger client problem, will I see a performance
change if I go to postgres?

Yes you will, but not for the better. HSQLDB has been shown to be faster than any other database but I don't know how good it is when it comes to large amount of data, that's why we don't usually recomend it as the DB to use for productional systems.

Marcel,

The session is not persistent. Neither are the subscriptions. (I believe)
the messages are also not persistent. Most have a very short lifetime. (The
idea is to deliver to those listening and get rid of it). (I didn't
implement all the clients so I can't be 100% sure that no client is
mistakenly publishing persistent messages, but I don't think so).

I'm not using a database, just flat files for storage. Is that a problem?



You have configured the default HSQL DB for persistency?:

  StoragePlugin[JDBC][1.0]=${JdbcStorage[HSQLDatabaseEngine]}
  QueuePlugin[JDBC][1.0]=${JdbcStorage[HSQLDatabaseEngine]}

What do you store in flat files?
