Hi, > error 90048
This is "file header of a database files (*.db) does not match the expected version". The database itself only writes the header once, and never overwrites it. This sounds like another application modified the database file. It doesn't sound like a bug in H2. > or 90030 That's a checksum mismatch. This also indicates the file was modified in another way. > one H2-DB for jackrabbit Apache Jackrabbit doesn't need MVCC. I suggest not to use MVCC for Jackrabbit, because it will not help at all, and it is slower. > 1) Is MVCC still unstable?

Yes. It also does that when using MVCC by the way. Regards, Thomas -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
