Unzip using zip390 ?

I have a requirement where in I am getting "X" number of zipped MVS file daily. And I have to unzip them. And then merge them to get a single file. I want this to be automated. I have the names of files of MVS and the the name of the .TXT file inside the archive of every zip file.

1) Can I do the merging before I unzip all of them. And then unzip a single file.>> Tried this way but was able to merge the zipped files. But when unzipping, I am able to get only first files contents in output.

2) Do I go ahead and unzip all of them first and then merge it.

3) Since I am getting all these files through my previous step of the job which is actually doing a copy of UNIX HFS files to MVS. I have thought that whether I can unzip or merge them along with OGET statement?
Not sure which path i should opt and go ahead.

To unzip a single file I am using below commands.

ACTION=UNZIP
MODE=BINARY
ARCHIVE=SEQ/AFILE
OFILE=SEQ/UNZIPF1;inventory1.txt

Where inventory1.txt is the file name inside archive.

Note- I have to unzip them using zip390.

Hello,

Suggest you do them individually until you have it all working.

Then, you can investigate combining things . . .

I am able to unzip them individually and then merge them.

The point is that there is no fix number of files that are coming everyday. This can vary. I need a approach where I can build such a SORT card or something which can help me to accomplish this task.

Hello,

When each new file arrives on the mainframe, unzip and copy it to the +1 of some gdg that is for this purpose. At the end of the day, run a job that names the gdg base and all generations will be processed - most recent first.

When reading the entire gdg, specify old,delete,keep for the disposition.

Lastly, create a new +1 that is an empty file for the processing of the next day.

Ok Dick, I tried with your way but little different appraoch. What I did till now is that I was able to merge all generations of MVS zip files in to one file.

Now I want to unzip them , when i unzipped this merged file which is actually a combination of various zipped generations. Then the output contains only record with last zipped file. other files contents are not populating.

I used this for my unzip:- (using ZIP390)

ACTION=UNZIP
MODE=BINARY
ARCHIVE=SEQ/AFILE
OFILE=SEQ/UNZIPF1

Can you tell me what I missing here?

Thanks!

Seems same to me Dick, Any different approach which I can follow and accomplish my task?

Hello,

No. If i had to do this, i'd do it as suggested.

A similar approach has been used Many times whtn multiple inputs have to be processed as one . . .

Hello Dick,

Finally we came to a conclusion to limit the file up to 10 and then create a job steps to to unzip them one by one and finally run a step that names the gdg base and all generations processed this way.

Good to hear you have an approach - thank you for letting us know

Keep in mind that after the entire set is processed, all of those generations need to be uncataloged.

And no job should create a new +1 while this job to consume those files is running.
