Max no of 100 communcations exceeded EP 7.0 NW 2004s SP14

Hi Experts,
Today we were experiencing a typical error on our portal while accessing one of our backend BW system.
The error read as
Connect to SAP Gateway failed
LOCATION CPIC(TCP/IP) on local host with Unicode
ERROR max no of 100 communications execeeded.
MODULE r3cpic_mt.c
We tested the connection of the RFC destination from the BW system and it also brought up the same error.
The same was resolved only after restarting the corresponding portal server node.
1.What is exact cause of this problem?
2.Where is the value for this max no of communication set in Portal?
3.How can we avoid this problem in future?
4.Any document or note which tells in detail about the communication between portal and backend sytems.
Thanks,
Jimmy

Hi Bala,
Sorry for the delay in reply.
So what you say is that the problem lies in the backend system i.e. our BW system and we need to change parameter on this system.
But I have note that the parameter disp/max_comm_entries and rdisp/max_arq both have current value 2000 on our BW system.
Can you please explain that how this CPIC conversations between a backend SAP system and SAP portal works?
Thanks,
Jimmy

Broadcast - ERROR max no of 100 conversations exceeded

We've scheduled 3 reports to email PDF's to approx 400 users but the BEx broadcaster only managed to send out about 80 emails. in the various logs and traces I can see and error that states "ERROR max no of 100 conversations exceeded".
I can find various notes about this refering to various sytstem parameters but as far as I can tell our parametrs are set correctly e.g.
gw/max_conn 500
gw/max_sys 300
gw/max_overflow_size 10000000
gw/max_shm_req 50
rdisp/tm_max_no 200
rdisp/max_comm_entries 500
As I understand it from the notes we should increase the environment variable CPIC_MAX_CONV. However the note I'm looking at (316877) states that this environment variable is on the ITS server but from talking to our Basis support the version of netweaver we are running doesnt have an ITS server?? Dont really know what all that means. Any ideas on that one or about the error message as a whole would be greatly appreciated.
If it's any help I can also see in SM21 that at the time of broadcasting the users got the error:
> Conversation ID: 33568780
> CPI-C function: CMSEND(SAP)
Communication error, CPIC return code 017, SAP return code 450
Thren in the broadcast log via RSRD_LOG the users have the error:
Java communication error: Error when opening an RFC connection RSBOLAP017

Max no of 100 conversations exceeded / CPIC-CALL

Hi All,
There are more than 4000 messages in SMQ2 Tcode and when we checked the SLDCHECK we got this error-:
RFC ping returned exception with message:
max no of 100 conversations exceeded / CPIC-CALL: 'ThSAPCMRCV' : cmRc=17 thRc=45
After increasing the value for parameter CPIC_MAX_CONV 1000 it started working but after 1 min SLDCHECK again gave the same error.
We have already checked and implemented the SAP Note :316877.
I have one doubt this Note says that CPIC_MAX_CONV value should be 5000,is it really required?
I have checked the SLDCHECK with value 1000 for CPIC_MAX_CONV .
Pls suggest the solution.
Regards,
Prashant

CPIC_MAX_CONV value should be 5000,is it really required?
No, this is not mandatory. You should set it as per the load on your system.
What is the error when you perform SLDCHECK?

Thanks
narpal

Hi Narpal,
By default Portal allows 100 simultaneous instant messaging sessions. But this number can be increased.
Navigate to
System Administration -> System Configuration -> Collaboration -> Real Time Collaboration (RTC) -> RTC Engine -> RTCEngine
- Switch to Advanced Mode
- Modify MaximumChatSessions parameter and set to 500
- Restart the Portal Server
The problem should be resolved then.

CPIC_MAX_CONV - ERROR max no of 100 conversations exceeded

I recvd the "ERROR max no of 100 conversations exceeded" and I could resolve it by setting the environment variable CPIC_MAX_CONV to a higher value for my <sid>adm per note 316877.
What I want to know is where can i check to see if this environment variable actually took effect WITHIN IN SAP (I can see it set in env and when I echo the variable) ? Can I see this anywhere within the SAP land ... in its server logs , property files etc ?
Also in general when we make changes to environment variables at the OS level pertinent to SAP then where within SAP does this get absorbed and where I can see the new values.
Pls advise.
thank you

Laxmi

Hi Laxmi,

Hi Hiten,
Make sure that you have set the parameter CPIC_MAX_CONV under Environment variables --> system Variables.
For XI, the recommended value for this parameter is 400.

So, I checked SAPFactory properties using Visual Admin but I think we got enough conenction.
Here is parameter.

How can fix this problem ?
Regards, Arnold.

Hi Arnold
When The external RFC/CPIC server cannot open any additioanl connections than u get
"ERROR max no of 100 conversations exceeded"
By setting the environment variables CPIC_MAX_CONV the library can manage more parallel connections
If an RFC server program registers with, for example, 100 threads at the R/3 gateway, 100 connections are initially kept in the server program. Every RFC running on this type of connection creates an additional entry in the connection list of the RFC server program. This means that, under full load, a maximum of 200 entries are possible.
I have not sure idea about "Maximum Connections" properties for SAPFactory in Connect Service

Max no of 100 conversations exceeded

Hello VC Experts,
I have developped a big VC application. within this there are included a lot of rfc call and functions.
sometimes it happens that the model break down because of the message above.
Does anybody know a solution except a redesign to end unnecessary rfc connections ?
I have already read sap note 314530 for searching a solution.
Thank you for help in advance.
Uwe

Hi Uwe,
I read note 314530. That means that you have a lot of RFCs which have over 200 Threads. Have you tried out to split your application in several nested iViews and put it together in one iView, so that not every RFC is active?
I never had this problem, so I have no solution for you, it's only a speculation with the nested iviews.
Best Regards,
marcel

Clarification about parameters to be changed for max no of 100 conv excd

Hi,
In our system we had received the error:
Connect to SAP gateway failed
Connect_PM TYPE=B MSHOST=xxxxxxxxxxxxxx GROUP=PUBLIC R3NAME=xxx MSSERV=sapmsXXX PCS=1
LOCATION CPIC (TCP/IP) on local host
ERROR max no of 100 conversations exceeded
due to which some users were unable to work in the system.
The threads that i have found while searching on the topic have suggested changing the parameter CPIC_MAX_CONV=500 (or greater) as per the note 314530.
And as mentioned in the SAP note 316877:
" Reduce ~timeout on the ITS machine to enforce the automatic termination of unused sessions."
Now in SMGW i can see the "Active Connections" (first page of the transaction) and also the drop down option "logged on clients" which gives another list.
I am now trying to understand which timeout parameter controls which list.
Most of the entries in the Active connections list are from the TP jlaunch (and seem to be coming from the java stack of the same system). And most of the entries in the Logged on clients list are from the TP SAPSLDAPI.
I need to know which timeout parameter (as per note 316877) needs to be changed for the problem being faced.
Or have i misunderstood this ~timeout parameter and it should be set in Windows environment similar to the CPIC_MAX_CONV parameter ?
Regards,
Rohan.

Hi,
Thanks for your responses.
I will be changing the CPIC_MAX_CONV parameter.
But I would still like to clarify about the other parameter : "~Timeout"
and be prepared to take action on this as well.
As per the (conflicting) information I have so far this seems to be some parameter that is to be maintained in each individual service in SICF ?
Or do we have any synonymous itsp* or gw* parameter which I can set for the timeout?
Regards,
Rohan.

AI_DIRECTORY_JCOSERVER - ConnTest issue Error "max no of 100 conversation"

I have a XI System (TXT)sitting on the WAS 640. Now the above mentioned RFC Connection (SM59) gives me an error saying "max no of 100 conversation". I searched on for this and found a SAP Note No. 316877. In the SAP Note which speakes abt Maximum Number of Converstion exceeded suggests to set the value for the CPIP_MAX_CONV variable to more than 100. I have kept the value 1000(One thousand) then too I am facing the same eror.
Apart from this there is a very strange thing that I have been noticed. In The TXT( XI System) if we go to the user list i.e. to T-Code SM04 then their are about 45 entries for the user XIRWBUSER.
Incase if I lock the user XIRWBUSER and then restart the Instance then I do not face any such poblems and also my AI_DIRECTORY_JCOSERVER Connection problem gets resolved. But This is not the solution , as I will be requireing the RWB user in my XI System for one or thjer other processes.
Kindly guide me in this case.

Premkishan Chourasia

Hello Vijaya,
Thanks a lot for your useful info.
I read the SAP Note 887880 and implemented the recommeded correction. My system is working fine now.

Max-reserved-bandwidth 100% for the interface

According to CCO as following text, the remaining 25 percent of bandwidth is used for overhead, including Layer 2 overhead, control traffic, and best-effort traffic. I want to know why cisco choose 25 percent. why not 30% or 20%?
If I config the max-reserved-bandwidth 100% for the interface, does it will effect the routing protocol? also effect the network conectivity?
thanks for your answer
=======
Usage Guidelines for max-reserved-bandwidth
The sum of all bandwidth allocation on an interface should not exceed 75 percent of the available bandwidth on an interface. The remaining 25 percent of bandwidth is used for overhead, including Layer 2 overhead, control traffic, and best-effort traffic.
If you need to allocate more than 75 percent for RSVP, CBWFQ, LLQ, IP RTP Priority, Frame Relay IP RTP Priority, and Frame Relay PIPQ, you can use the max-reserved-bandwidth command. The percent argument specifies the maximum percentage of the total interface bandwidth that can be used.
If you do use the max-reserved-bandwidth command, make sure that not too much bandwidth is taken away from best-effort and control traffic.
The max-reserved-bandwidth command is intended for use on main interfaces only; it has no effect on virtual circuits (VCs) or ATM permanent virtual circuits (PVCs).

DpVmCheck: max number of priv VMs exceeded (1 0, timeout)

Hello,
In our CRM system EHP1 FOR CRM 7 ABAP ,users get this screen mainly for big contracts at different stages like collision run,saving.

I have already gone through notes 1757252
But the parameter rdisp/max_vm_priv_time and rdisp/max_vm_priv_no doesn't exist in our system. Instead is there any other parameter which we can use in our release ?

Any thoughts? Wireless users are experiencing random disconnects.

In looking at the radius configuration again I notice that we have two servers defined. I looked through the logs and didn't see anything alarming, until I checked the secondary radius server. I was just told that the second radius server has been shutdown without notice.
I will remove that from the WLAN config later tonight.
Obvious question, but will ask it anyway, will this cause these errors?
