    Hypersonic won't start!

    drej Newbie

      Hello,

      I really hope someone is knowledgable in this area. Basically Hypersonic was working fine with a mini-app of mine. My app was adding a series of small images (30KB each) to the db (via client calls to a session bean, then to an entity bean) , when it crashed. Now when I start JBOSS (ver.3.2.0) , I get the following errors:

      And there are many more lines of hex values. It seems it cannot connect because there was a commit problem. I would just like to wipe the slate clean so I can connect to Hypersonic again.

      Thanks for your time.

          try to start it from the minimal configuraton with Hypersonic service

          (I gues you are now using default)
          JBOSS_HOME/bin/run.sh -c minimal


          have no other clues

            Well, I've found the answer to my question after much searching. Basically, when you're adding data to your Hypersonic database, even though it stores all the data in memory, any changes are saved in a text script file, such that the database can be recreated when Hypersonic restarts. Unfortunately, this is a simple text file and can get very large, very soon, especially if you're saving any binary data to the db. Anyway, for various reasons (I ran out of disk quota, so the script was incomplete), the script may get corrupt and you'll get messges similar to what I had in the original post. To get rid of those messages and have Hyperonic work again you have to delete the corrupt script file that Hypersonic generated, as follows:

            1. Shutdown the JBOSS server if it's running.
            2. Go to the directory: jboss-3.2.0/server/default/data/hypersonic
            This is the folder that holds the script file for the database and a properties file. If you delete these files, the default ones will be recreated when you restart JBOSS. Note that deleting these files will essentially delete the data in your database.
            3. Restart JBOSS and you should be okay with a clean database.
