I have an compressed file on Unix Box. Now i have to get the file onto datastage and do some processing on it. So first i have to uncompress the file and then do th processing. But how can i uncompress it using any stage. Expand stage does that when the file is on its input. Now through which stage i have to pull the compressed file and fed it to expand stage to uncompress. Sequential file is not reading the compressed file. Please help

WHY is Sequential File stage not reading the compressed file? What error message is generated? What record schema are you using?

Have you considered using a Filter command (uncompress filename.Z) in the Sequential File stage?

using external stage also you can read zip files..

In the sequential file stage, did you set the filter option?

If the file is mydatafile.Z, then it is compressed with the standard Unix compress. *.gz is the Gnu version using gzip.

filter = gzip -cd
or
filter = uncompress
or
filter = gunzip -cd
