An error occurred when executing a Remote Function Call.

"Protocol error when communicating with SAPGUI."

Status of connection.... "RFC DRV=GUI INPUT"

Internal error code.... "RFC_IO20"

Hi Prasanth,

Setting it in Default profile, will be applicable for all the instances,

If you are setting it in Instance profiles, then you need to set it in all the instances profiles of application servers.

In that case we will have to restart the server also. correct me if i m wrong.

what does this rdisp/reset_online_during_debug parameter signifies?

Hi All,

We are getting this error in CI and two DI's , Do i need to restart the server after adding this parameter in Default or Instance profile?

Your question has been answered earlier in this thread.... pay attention to the replies you get.

Setting it in Default profile, will be applicable for all the instances,
If you are setting it in Instance profiles, then you need to set it in all the instances profiles of application servers.

Also... if the parameter is not dynamic then you need to restart the whole system (meaning CI and all DI's)

Hi Prashanth,

Check if the OSS note:1079446 is relavant.

Hi Vijay,

Thanks for ur help. SAP Note 1079446 says there is some prob with kernel. Does it mean after applying latest kernel this error will be come? or this is happening due to network issue?

Hi All,

SAP Note 1079446 gives this soln-:

Solution

To avoid the problem, set the profile parameter rdisp/reset_online_during_debug = 1 (not documented) in the instance profile. This parameter is available in the kernel patches mentioned in the Support Package patch levels.

our SAP kernel is : 640_REL and patch level: 217 latest is 247

Setting the rdisp/reset_online_during_debug = 1 will solve the problem?or we need to upgrade the kernel also?

Wat is the meaning of not documented?

Regards,

Prashant

Hi Prashanth,

You already seems to be having a patch higher that that mentioned in the note.

Is the OSS note relevant, in your case, i.e are the dumps are being generated during the "RFC debugging of a function module"

as mentioned in the note, and also check other terms mentioned in the note,

If it is relevant then you need to set the profile parameter as mentioned in the note.

Regards,

Vijay.

[Former Member]

Thanks Vijay,

Do we need to set this profile parameter in default profile?

one more thing we are planing to update our kernel is it really required at this point of time or our current level is okay?

Regards,

Prashant

[Former Member]

Hi Prashanth,

I think Setting in default profile would be good,

but you have to decide on the kernel upgrade, based on you kernel upgrade plan.

Vijay.

Hi Vijay,

Thanks for the reply, We have CI on Unix and 4 dialog instances on windows NT server. We are getting this error in all the servers.Do we need to set this in only CI or each one?means including all Apps servers?

Is it required to restart the server after setting this parameter and what does this parameter signifies?

Regards,

Prashant
