SAP Comunication Errors CPIC 20 SAP=474

[Former Member]

Hi

We decide to go from kernel 7.00 to 721_ext on AIX 7.1. Locally on the same server we run c-program wich connect to GW of SAP.

Before we did not experienced no such kind of errors.

Now, the rfc start to die with the error:

** Trace file opened at 20150618 081107 CEST, by disp+work

Just to be clear we do not terminate any connections manually.

Any help is welcomed.

I had the same issue a few years ago, for the life I cant remember.

I believe the fix might have been an instance parameter I had to add.

Oh sorry I cant remember

A new 'feature' of SAP regarding the gateway is to look into parameter, gw/acl_mode and see if it is enabled as 1.  If so, change it to 0 via RZ11 as it is dynamic and then retest. 

You may also need to look into creating a secinfo and reginfo files and edit them at the OS level to enable security restrictions.  Check out the following link for more information:

I do not see how this would be related to the return code 474...

[Former Member]

I was referring to the thread regarding the gateway settings.  Sorry, I should have responded to that thread rather than the main thread.

Hi Franco,

Thanks for sharing the file.

GwICheckFrag: no write to client genadev0/SAPCPIC (idx 22, hdl 211) within 120 seconds, disconnect now

Have a look with SAP Note 1141791 - Gateway: Connections hang during fragmented write operations

Hope this will help you .

Pay attention to parameters gw/reg_info and gw/sec_info. For more info you can start read with Making Security Settings for External Programs - SAP Gateway - SAP Library.

[Former Member]

Hi

Thanks for your respond, but what I understand you need to define this only for remote connections on a other server.

Hi Franco,

check the below things.

- Run the SMGW transaction and check whether your gateway is active or not.

- paste the screenshot of RFC details.

With Regards

Hi Ashutosh

On the SMGW the connections disappeard and are not active anymore.

So if you need some other detail let me know.

This could be for interest. The sideinfo file we use:

DEST=SAPNODE

LU=genadev0007

TP=sapdp00

PROTOCOL=I

GWHOST=genadev0007

GWSERV=sapgw00

KEEP_SESSION=1

Franco
