Hi,
can we use CheckSum in PX environment ?
may be a dumb question - when i tried in PX job it says function not there, but tried search in PX message board i found 3 hits.

thanks

Let us know what you find out.

I have only used PX. I know what a checksum is but have never used it in DataStage. You have used in Server? How does it work? Does it do a checksum per record? Does it require the layout of the record to be defined or can it do it against a raw datatype?

Just yesterday I was asked about checksum, so if it is available in PX, we may be able to take advantage of it.

Brad.

Checksum() is a BASIC function, so not directly available in parallel jobs.

You can access it via a BASIC Transformer stage in a parallel job, with the concomitant overheads of data type translation that this incurs.

You could also access it via server job componentry in a server shared container that had been used in the parallel job, with even greater overheads, such as execution only on the DataStage server machine.
