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)");

Is:
A) The value of targetDSN and sourceDSN the PDS name only?
B) or is the (member) included?

If B then that is your issue. You should allocate with just the PDS name. You can not allocate a member with bpxwydn or any utility (as far as I know).

To use code tags, I highlite the code below and click Code box above.
Code:
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

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.

1) Carefully print the result of this terrible concatenation producing the parameter for BPXWDYN

2) Run as many tests as needed to execute this resulting ALLOC command manually, in TSO environment.

3) When you are sure the ALLOC command itself is working as desired, you can start incorporating all your garbage into your terrible code.

4) Do not forget to trace carefully every intermediate step: the clear input and output produced by every your statement.

5) Do not suppose that forum members have to do your own job for you. You have to present all detailed information to the forum, and - to be polite - you must format all your input in a readable way, not in the form as if it was taken from a trash.

Let us know if this statement is clear?

You can not allocate a pds(with member) as NEW.

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.

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
