Hello,

We are runing ITX Batch Command Server 9.0.0.2(96)_31bit in mainframe Z/os.

We have a huge XML-document input. The run gives error:

MSG ID 4136 - FUNC:GetDataPtr DISK READ ERROR Asked:-4294967278 Got:18 bytes  - ./s_paging.c 2043
Mapping return code 17, severity ERROR:
Disk read error                      

In Audit log we can see that input has been read succesfully and two outputs has been written successfully:

<SourceReport   card="1"   adapter="File"   bytes="2460256545"   adapterreturn="0">
   <Message>Data read successfully</Message> 

<TargetReport   card="1"   adapter="File"   bytes="1502"   adapterreturn="0">
<Message>Data written successfully</Message>

<TargetReport   card="2"   adapter="File"   bytes="2136438508"   adapterreturn="0">
<Message>Data written successfully</Message>

In Audit log WorkArea files looks like this:

<WorkArea type="File">                                                        
<inputarea  card="1"   Path="DD:SYSTMP03" TimeStamp="14:39:48 April 9, 2018" bytes="1668018489"/>
<outputarea card="1"   Path="DD:SYSTMP05" TimeStamp="14:42:24 April 9, 2018" bytes="65536"/>
<outputarea card="2"   Path="DD:SYSTMP07" TimeStamp="14:42:36 April 9, 2018" bytes="0"/>
</WorkArea>  

I found it a little bit strange that SYSTMP07 bytes are zero.

I have no idea what is wrong.

Any help is appreciated.

Most likely a boundary overrun condition.  What version are you using?

I recommend you raise a Service Request (PMR) with IBM and provide a complete testcase, along with JCL and dataset definitions for the inputs.

Thank you.

Thank you Paul  for your answer,

We are runing ITX Batch Command Server 9.0.0.2(96)_31bit in mainframe Z/os.

Our Z/os system programmer put this defition for temp file SYSTMP06 to JCL
SPACE=(CYL,(4000,333)),UNIT=VIO
With this one the batch job runs fine.

Earlier the definition for temp file SYSTMP06 was
SPACE=(CYL,(9999,9999)),DSNTYPE=LARGE

What do mean by boundary overrun condition ?

Some piece of data is supposed to fit exactly in an area of memory reserved for it, but it is actually larger.

Thank you.
