Hi,
I have several homogeneous SUSE 9 Nodes. I am running BDB4.3.28 with
following configuration parameters.
DB Flags = DB_CREATE| DB_AUTO_COMMIT|DB_THREAD;
Env Flags = DB_RECOVER |DB_CREATE | DB_INIT_LOG | DB_INIT_MPOOL |
DB_INIT_TXN|DB_THREAD;
I have configured transaction subsystem with DB_TXN_WRITE_NOSYNC|
DB_LOG_AUTOREMOVE options.
I want to copy the DB from one machine to another machine. Suggested
method is using db_dump and db_load. But this transfer has to be done
every 5 minutes, so using db_dump and db_load is not possible as it
takes lot of time.
The DB File, Region Files and Log files are present in the same
directory. I want to copy this whole directory and start the new
node. Out of following 4 options which is best and guaranteed to
work. I have tried option 1 and it failed.
1. copy only db file ( This method failed some times. I am performing
dbsync() before transferring the db file). )
2. copy db file and region files only - no logfile
3. copy db file and log files only - no region files)
4. copy all files.
Please give your suggestions.
Regards,
Kiran
