Newbie Stuck on "Duplicate Dataset Name"

Travis Byzewski · New User Joined: 03 Apr 2023 Posts: 3 Location: USA

i keep getting this message on my IBM z/OS Boot Camp, I deleted the old datasets and made new ones, but I'm lost on how this is a duplicate, the IBM help section chat doesn't have anyone at the helm right now so I thought I'd try here.

I would really appreciate some help, I don't have much time left with the mainframe and could use some direction.

I did a search and found someone with the same issue, but none of those solutions worked for me. ibmmainframes.com/about41758.html

I'm still trying to wrap my head around a lot of this and usually I just look at it until I figure it out, but I've been stuck on this for too long and could use some help.

Thanks

It seems like there are two different problems:

1. duplicate data set exists
2. data set already cataloged

You probably issued some ALLOCATE commands that worked earlier. You need to clean up the old. Various ideas come to mind:

1. Use LISTCAT command to verify that the catalog thinks it is on volume SMS262.
2. If not the right volume, use DELETE ... NOSCR to remove catalog entry
3. Use ISPF 3.4 and specify SMS262 for volume. use DEFINE NONVSAM command to create a matching catalog entry.

Then you can DELETE and try your ALLOCATE commands again.

You will have to look at command syntax for complete parameters.

fyi, you can search internet for:

igd17001i site:ibm.com
igd17101i site:ibm.com

which are the messages shown in your screen capture.

To clean up the mess you should..

a) Check if your user has an ALIAS defined
b) DEL 'dsn' PRG /* delete catalog entry */
c) DEF NVSAM(NAME('dsn') VOL(SMS262) DEVT(3390) RCTLG) /* recatalog what's on SMS262 */
d) see b)
