I'm not sure what the problem is. I guess you need to use the Recover
tool. I have some questions:
- Could you send the full stack trace of the exception including message text?
- Did you use multiple connections?
- A workarounds is: use the tool org.h2.tools.Recover to create
the SQL script file, and then re-create the database using this script.
Does it work when you do this?
- With which version of H2 was this database created?
You can find it out using:
select * from information_schema.settings where name='CREATE_BUILD'
or have a look in the SQL script created by the recover tool.
- Did the application run out of memory (once, or multiple times)?
- Do you use any settings or special features (for example, the setting
LOG=0, or two phase commit, linked tables, cache settings)?
- Do you use any H2-specific system properties?
- Is the application multi-threaded?
- What operating system, file system, and virtual machine
(java -version) do you use?
- How did you start the Java process (java -Xmx... and so on)?
- To you use temporary tables?
- Is it (or was it at some point) a networked file system?
- How big is the database (file sizes)?
- How much heap memory does the Java process have?
- Is the database usually closed normally, or is process terminated
forcefully or the computer switched off?
- Is it possible to reproduce this problem using a fresh database
(sometimes, or always)?
- Are there any other exceptions (maybe in the .trace.db file)?
Could you send them please?
- Do you still have any .trace.db files, and if yes could you send them?
- Could you send the .h2.db file where this exception occurs?
Regards,
Thomas
