Create a Shared container with a hash file for parallel

ady · Post by **ady** » Thu Dec 21, 2006 1:24 pm

I need to use a hashfile which is a output from a serverjob as a shared container in parallel. My questions is

1) how can I create a container with only the hashfile ?

2) can I write the hashfile to a seq file and use it as a lookup file set ?, do I need to take any precautions when I am writing hash to seq ?

It's "hashed" file, not hash file.

1) You can create a server shared container and use that in a parallel job, provided that the restrictions described in Chapter 2 of the Parallel Job Developer's Guide about incorporating server components are observed.

2) Yes, but the job that dumps the hashed file into a sequential file will run sequentially, and therefore may as well be a server job. You can not use a sequential file as a Lookup File Set, as they have different internal structures. But you can use a sequential file to feed a reference link; in either case the data are first loaded into a virtual Data Set. Lookups are performed against the virtual Data Set (except in the case of sparse lookups, which are only possible against database tables, e.g. DB2 and Oracle).
