Merging Log Files with same name

2657918

Hello,

I have log files with same name 00000000.jdb (because created at different machines). I would like to merge data stored in these two files.

I tried below approaches which do not work:

1. rename one of the files -> doesn't work as file header has file name info which doesn't match with renamed value

2. db dump/load -> dump and load works without error. (i have to dump Entity related Database and Format related Database -- from -l option) However when i try to read the file, it gives error.

Exception in thread "main" com.sleepycat.je.EnvironmentFailureException: (JE 5.0.103) Catalog could not be refreshed, may indicate corruption, errorFormatId=52 nFormats=51, . UNEXPECTED_EXCEPTION: Unexpected internal Exception, may have side effects.

I am using EntityStore and thus Annotated Entities.

Does any one has any insights?

Thanks.

Well, i did some changes in application so as merge data from other environment; however i was hoping copying files to existing env should have worked.

Yuvaraj,

As you discovered, it is not possible to use .jdb files from one environment in a different environment.  The .jdb files use an internal format with relationships between files that form the Btree.

I'm glad to hear you were able to use DbDump and DbLoad successfully.
