RE: JAVA400-L Digest, Vol 6, Issue 201

Thorbjorn,

How do I check the jvm's memory pool? And how do I check the disk i/o?

Under Work with Threads, the Aux I/O is busy and increasing steadily but under Display Open File, the Relative Record and I/O Count are not changing.

The question remains, what can I do to make this process work faster?


Thanks,

Marvin

Can anyone tell me why it suddenly when from 30k records in the first hour to only a few hundred records in the next hour? But more importantly, is there anything I can do short of multiple files, to help the program process the file faster?

Is your memory pool large enough for the jvm? Check for disk i/o.
