Issue/Introduction

Transactions with CICS are getting  abend X005  and  rolling out  after applying  PTF SO08256  /  SO08257 which is dependent on session display size (Dynamic display size 3270).

Environment

Release : 19.0

Cause

The #UCFUTD default page and line length is 24 and 80, that of a Mod2.
If the emulator's alternate screen size is other than a supported 3270 model (dynamic), the emulator's default screen size cannot be a Mod 5.

Resolution

The DFLTSIZ specification only applies if the alternate size is not a supported 3270 model. To support a Mod4 as the alternate, it may be necessary to use a TYPETERM designation in CICS
It is recommended not to specify DFLTSIZ for either #UCFCICS or #UCFUTD .

Here's an example of a front-end table that defines a complement of 3270 models.

UCFFET #UCFUFT SYSTEM=CICS,NTID=CV08,PTID=UCFP
#UCFUTD TYPE=TTY,NCHARS=80,NLINES=2
#UCFUTD TYPE=T3277,NCHARS=80,NLINES=24,MODEL=2  
#UCFUTD TYPE=T3279,NCHARS=80,NLINES=24,MODEL=2  
#UCFUTD TYPE=T3277,NCHARS=80,NLINES=32,MODEL=3  
#UCFUTD TYPE=T3279,NCHARS=80,NLINES=32,MODEL=3  
#UCFUTD TYPE=T3277,NCHARS=80,NLINES=43,MODEL=4  
#UCFUTD TYPE=T3279,NCHARS=80,NLINES=43,MODEL=4  
#UCFUTD TYPE=T3277,NCHARS=132,NLINES=27,MODEL=5 
#UCFUTD TYPE=T3279,NCHARS=132,NLINES=27,MODEL=5 

The X005 can also be caused by using an old  #UCFCICS macro without the SO08256/SO08257 changes applied. 
Ensure the  CICS front-end table is assembled and linked with the latest  #UCFCICS macro in the CAGJMAC library.
