Hi,
I am having issue in reading the CWA data in my COBOL program. And in order to debug that I need to view the data in the CWA.
Is there any command to view the data in the CWA without using a separate COBOL program. Like CEBR to read TSQ data. I know one way is to take a whole region dump and examine the dump. But this is more expensive and time consuming.
Could you suggest any ways to read the CWA data.
Thanks for your time looking into this. |

I have looked into CECI. But that enables me only to read some files or TDQ.. Not CWA.. Appreciate if you could provide any specific commands to read CWA using CECI.
And ADDRESS, this doesn't help me to read the data. This returns me some HEX address space, which I already have. I need to read the data at that address space. |

| You could always invoke CEDF on any transaction and from there invoke CECI to get the address of the CWA and view it directly with the CEDF's storage viewing |

Ever since CICS/ESA 4.1, you can invoke CECI from CEDF. Place your terminal under CEDF and enter an eligible transid. After getting past "PROGRAM INITIATION", press <PF5> (Working-Storage), then press <PF5> again and you will have launched CECI. Issue the ADDRESS API and copy the CWA address, press <PF3> and you'll be returned to Working-Storage. At the top of this screen, paste in the CWA address and press <Enter>. You'll now be viewing the CWA data. If the CWA length is unknown, while you're in CECI, issue an ASSIGN CWALENG API.
You'll need to map the CWA data with a copy of the CWA layout from your application system.

thanks Bill & Guy for ur suggestion..
I may be putting more constraints.. I am having problem in my production environment, so I am not allowed to use CEDF 
Can you recall any other ways ? |

Hello,
Someone has permission to use CEDF in production. . .
Work with them or tell your management that you need permission to do this temporarily to resolve the issue. |

Thats odd, you are responsible for an application that uses the
CWA, but you can access CECI and NOT CEDF in your production
region.
As Dick suggests, talk to your management. |

If you are authorized to use TMON for CICS, logon, then look for selection "STORAGE ANALYSIS", then "CICS CONTROL BLOCKS", then "CSA COMMON SYSTEM AREA". Place you cursor under the CSA address and press <Enter>. Then on the command line, enter FLD=CSACWAA and press <Enter>. Place your cursor under the address associated with CSACWAA and press <Enter>. You are now viewing the CWA associated with the given region.
If you need the CWA length, from "CICS CONTROL BLOCKS", locate "SIT SYSTEM INITIALIZATION TABLE", place your cursor under this and press <Enter>. Then on the command line, enter FLD=SITCWA and press <Enter>. This will give you the CWA length as a binary-halfword in hex.

A correction. The CWA length is adjacent to the CWA address in the CSA as a binary-halfword. You don't have to look at the SIT unless you're curious.

Bill,
That was a great input. We do not have TMON in my site, but have Omegamon. I am pursuing if I can use Omegamon to read CWA data. |
