perst database corrupted

[Slava Pankov]

From time to time perst database is getting corrupted (and it's hard to figure out which steps cause that).

After that jease cannot start anymore.

The question is if there is any tool for repairing perst database?

[Slava Pankov]

Answering to myself :-) There is no any kind of perst database repair utility. The only way is export to xml, and then import back to db. But it works only in limited number of cases, often db remains corrupted and only previous backup can help.

I've tried to change in PersistenceEnginePerst.java the following setting: db.setProperty("perst.file.noflush", Boolean.FALSE); 

Still have no reliable statistics if it's getting better for preventing perst db corruption.
