google:”Berkeley DB” (aka google:”SleepyCat”) is used in google:”DSEE” and Messaging Server. So, this VM contains many bdb datafiles created by 64-bit bdb library/executables.
This image is 64-bit only.
So, when I started this VM on 32-bit machine, DSEE failed to start. I know it. DSEE does not support copying over bdb files over to different platform. Apparently, google:”OpenLDAP” doesn’t either.
The ID’s do not have a fixed, platform-independent, data-type associated with them, i.e. on 32-bit platforms the ID’s are 32-bit integer values and on 64-bit platforms the ID’s are 64-bit integer values.
But, in the rare hope that it would work, I edited several text files, among which was google:”dse.ldif”. The error finally reduced to __db.001 file. I googled and found a hint at google:”RedHat package management”.
I have used RedHat around 15 years and didn’t know BerkeleyDB was used there.
it’s deep internals of BDB and contains inherently architecture-dependent data like pointers to memory IIRC
I removed __db.001 files and , finally, DSEE631 32-bit started fine!
But this way of migrating data is not supported. In fact, if index was there or datafile was 8GB large, it may not work.
