DataSet member creation failed with BPXWDYN failed;

raminenibhanu · Posted: Mon Jan 31, 2022 10:57 pm

Trying to create a member DataSet and it failed with the below error message. Please let me know how to address this issue.?

com.ibm.jzos.RcException: BPXWDYN failed; error in keyword number: 5 RC=-25 (0xffffffe7)
at com.ibm.jzos.ZFile.bpxwdyn(ZFile.java:152)

Input Data

ReadWriteDS :PDS(TEST1)
ReadWriteDS :PDS(TEST3)
zFileInDS initialzied1 :USER.PDS(TEST1)
SourceDSN : USER.PDS(TEST1)
targetDSN : USER.PDS(TEST3)

Code

public ZFile createDSN(String datasetName,String templateDSName) throws Exception
{
ZFile zFileOut = null;
String targetDD = ZFile.allocDummyDDName();

// bpxwdyn requires fully-qualfied dsn (it will not add uid).
// so we make sure that we have a fully qualified DSNs
String sourceDSN = templateDSName;
System.out.println("SourceDSN : "+sourceDSN);
String targetDSN = ZFile.getFullyQualifiedDSN(datasetName);
System.out.println("targetDSN : "+targetDSN);
try{

ZFile.bpxwdyn("alloc fi(" + targetDD + ") da(" + targetDSN
+ ") like(" + sourceDSN + ") reuse new catalog msg(wtp)");

zFileOut = new ZFile("//DD:" + targetDD, "wb,type=record,noseek");

}catch(Exception e) {
e.printStackTrace();}
return zFileOut;
}[/code]

CODE TAGS ?

Getting error at the below command. Same command works for regular datasets creation, but for member dataset creation its failing.

ZFile.bpxwdyn("alloc fi(" + targetDD + ") da(" + targetDSN
+ ") like(" + sourceDSN + ") reuse new catalog msg(wtp)");

Dave,

Value of the target DSN & Source DSN are below and members included

SourceDSN : USER.PDS(TEST1)
targetDSN : USER.PDS(TEST3)

thanks
Bhanu

I am not sure what all your code is trying to do, but you can not allocate a PDS with the (member) attached.

The PDS should be created NEW ONCE (without the member).

Then perhaps allocate as SHR afterwards (with the member),
then copy/write to to that allocated DD.

I say perhaps because the information vague.

Alloc cmd :alloc fi(SYS00009) da(USER.PDS(TEST6)) like(USER.PDS(TEST1)) reuse new catalog msg(wtp)

what are the options that I need to pass for PDS with member

reuse new catalog msg(wtp) -- tried it didnt work.

I am getting very tired here. This is my last try to help.

From my earlier post (did you read it?)

I am not sure what all your code is trying to do, but you can not allocate a PDS with the (member) attached as new.

1) The PDS should be created NEW ONCE (without the member).

2) Then perhaps allocate as SHR afterwards (with the member)

3) Then copy/write to to that allocated DD.

thanks Dave for the information. Will try your recommendations.

It is important to understand that specifying a member name in the data set name sent to BPXWDYN does not actually create the member.

To actually create the member you must then run a program that writes data to the "file" created by BPXWDYN. This program can be the program that calls BPXWDYN, or another program the specifies the "file" created by BPXWDYN.

Allocate the dataset without specifying the member name at the end.

Alloc cmd :alloc fi(SYS00009) da(USER.PDS) like(USER.PDS) reuse new catalog msg(wtp)

After it's created, then you can write to the dataset specifying a member name on the end USER.PDS(TEST6). In fact you have to write to it that way, otherwise it destroys the datasets directory making it unusable.

I suggest you read about the LIKE parameter as it may not work exactly as you expect. It can affect the way the SMS ACS routines work as well because some of the read only variable are not passed using LIKE
