Mainframe, MVS and zOS Discussion

Thanks Anuj. 

zum13Many large businesses have huge investments in mainframe technology as the means of running their businesses. Migrating that functionality to another platform would be incredibly expensive to do so the alternative is to move away from the paradigm of the mainframe as being a thing solely for r...

Thank you so much zum13, this is very helpful.

DB2Explain the effects of using CURSOR WITH HOLD with GROUP BY and ORDER BY clauses in your queries.

Hi,

Does any one have idea about rc 1000 in JCL?
 

Happy New Year everyone!

Hi,

Thanks for the reply. I want to test the query in SPUFI and QMF and later use the query in COBOL program.

How to get top 5 rows from table thru SQL?

Thanks.

I have seen people using MVS also but not MFT or MVT. But as you said, IBM documents still use MVS, perhaps that makes to use it.

Hi,

My question is perhaps offtopic but this has been haunting me. What is more appropriate to use between OS390 versus zOS? I have seen people are using these terms, usually, interchangibly. Is not it that OS390 is among the initial releases of the operating system? And it's zOS now.

Yes, that's the only option I am also thinking of now.

The result of the function YEAR should be large integer (S9(09) COMP) and should be defined as binary of 4 bytes. Change the host variable definition and see if it works. And if it does, you should read back what Enrico has said initially and you'll realize that you had the answer right there. :) T...

hmmm,,ok Thanks.

Hi - From manuals and some tests, I have checked that in z/OS 2.1 a PDSE can be of two different types - type 1 or 2. Manual  gives information about DSINFO and it has been enhanced to set the variable, ZDSDSNV, to indicate if the PDSE is version 1 or 2. But I don't find a similar variable for LISTD...

Thanks enrico. A VALUE CANNOT BE ASSIGNED TO OUTPUT HOST VARIABLE NUMBER position-number BECAUSE THE DATA TYPES ARE NOT COMPARABLE Explanation A CALL, FETCH, SELECT, VALUES INTO, or SET statement with an output host variable could not be performed because the data type of a variable was not compatib...

Thanks all for explanation. I did look at the documentation before posting it here. I should have told about that. But the documentation does not say if IKJEFT1A is better, bad, good or something else when used in place of IKJEFT01 for a DB2 Job. Or there is just no difference as long as we are usin...
