PCB address in BMP
Posted: Wed Aug 17, 2011 2:35 pm
In running a BMP program, I encoutered U0476 abend.
I think the problem is "INVALID PCB ADDRESS"
I want to know,how i can pass the pcb number to my cobol program?
my psb just have 1 pcb:
* PCB NO. 1
PCB TYPE=DB,DBDNAME=RETDTRAN, *
all the best,

It depends on how you are invoking IMS - if you are using DFSRRC00 then U0476 menas, a DL/I call does not include a valid PCB address as you also have said. The PCB address in the DL/I call (second parameter or third, if count is the first parameter) is not one of the PCB addresses passed to the application program at its entry point.
I'm not sure if you've looked for it or not, however for such a generic question I'd say, the DFSRRC00 Parameters differ depending from the execution environment (BMP, DBB, JMP, ...). The symbols in the JCL might be different at different sites, but the meaning remains the same.
Please have a look at the IMS Installation Guide Volume 2: System Definition and Tailering. You can use the following link to get there -
http://publib.boulder.ibm.com/infocente ... /index.jsp
Look for the procedure descriptions, e.g. IMSBATCH is the name for the BMP. Right after the sample JCL in section IMSBATCH Procedure Parameters is a list of all applicable DFSRRC00 symbols for this execution environment, for which the meaning can be looked up in section Parameter Description in the same book.
This applies to IMS V9 or earlier.

As you are sing CMPAT=YES in PSBGEN, DLI will internally use one PCB for checkpoint restart. You have to have two pcbs in linkage section. First one should be IO-PCB. Seocnd one is the pcb for your DB RETDTRAN. Similary you have to use these two pcbs in DLITCBL or PROCEDURE DIVISION USING IO-PCB,RETDTRAN-PCB statement. If you dont want IO-PCB, remove CMPAT=YES in PSBGEN. Hope this explains
