• OPS/MVS Event Management & Automation

Issue/Introduction

Running the following Rexx, to schedule an OPS/REXX EXEC to run asynchronously in an OSF TSO server address space : 

txt =   '192.0.2.1:4567 2 |',                             
        '2020-05-22T192.0.2.2 |',                          
        FQ' | ZN | ZOS |',                                     
        'OPSMAIN | Z-SW-TDS-IMS_ALERTS | 'EC' |',              
        'AUTO_IMS-CZY117A | EVENTMGT-EMAIL |',                 
        'EAXI701E IMS CZY117A DFS3127I READ ERROR OCCURRED',   
        'ON THE RESTART DATA SET WIBBLE WOBBLE WABBLE 11:27'   
Say Length(txt)                                                
Say Txt                                                        
Address 'OSF' 'OI rexxpgm' txt                                
Say RC      

it can happen that the argument txt is getting truncated at 244 characters:
...

OPS3724T TSO WTO1 Sent CMD=OI EAXHPMSG 128.212.230.49:4567 2 | 2020-05-22T11.27.3302.00 | RUPXXXX-RV00.DE.XXX.COM | Z

OPS3726T N | ZOS | OPSMAIN | Z-SW-TDS-IMS_ALERTS | RUPXXXX | AUTO_IMS-CZY117A | EVENTMGT-EMAIL | EAXI701E IMS CZY117A DFS3127              

OPS3726T I READ ERROR OCCURRED ON THE RESTART DATA SET WIBB         

...

Is there a Parm or an OSF setting that limits the amount of characters being parse'd to a rexx ?  How to solve this issue? 

 

Environment

Release :  

Component : OPS/MVS

Resolution

The ADDRESS OSF 'OI...' arg  instruction is executed in an OPSOSF Server address space.

If the //SYSTSIN DD of the OPSOSF proc used, looks like the following: 

//SYSTSIN DD SUBSYS=&SSID,DISP=SHR,DSN=PDEIX.CAO.&SYSNAME..OSFIN,
// DCB=BLKSIZE=256

then the BLKSIZE value can limit/truncate the argument parm passed to the rexxpgm. 

In order to correct the situation, the following definition should be used :  
 
//SYSTSIN DD SUBSYS=&SSID,DISP=SHR,DSN=SYS2.OPS.ST02.OSFIN,
// DCB=(BLKSIZE=6144,LRECL=6144)
