File loading suddenly slow in Informatica

Mike Lampa

Published: 03 Sep 2003

We are facing a strange problem in Informatica. We are loading data from mainframe flat files into other flat files using some transformations. This job used to run smoothly and was faster earlier, but today it is taking a hell of a lot of time. The log file says that cannot write the cache file; we have checked the write permissions and the size -- they are OK. Can you please give us any insight as to why this is hapening?

As an informatica user you should be eligible to join the developer network they have. They have a great bulletin board for you to place a question and others will other their experience. Another good place is Core Integrations Web site. Sign up to be a part of their InnerCore. It's another great forum for technicians to bounce ideas off each other.
