Hello
I am trying to reload a database in keyorder to possible improve i/o performance for large datasets.

I have tried to take a dump of the database in a file using DbDump and try to load the database back into the environment using DbLoad. However, it fails and I get an error message as the trace below provides

java -jar /home/desikan/workspace/IBServer/dist/lib/je-3.3.74.jar DbDump -h /home/desikan/Desktop/DbLoadTest/ -s E10000Store_ESet_INTEGER -f /home/desikan/dumpeddatabases/test1.txt

java -jar /home/desikan/workspace/IBServer/dist/lib/je-3.3.74.jar DbLoad -f /home/desikan/dumpeddatabases/test1.txt -T -s E10000Store_ESet_INTEGER -h /home/desikan/Desktop/DbLoadTest

Can you point out what was wrong in my loading procedure. And also if you can provide the insight into the overall strategy of using DbLoad and DbDump for reloading a database in key order, it would be great.

Thanks
