Cannot connect to server using message server: ms://<XXXXXX>:8100/P4

Hi experts,

I am getting an error when I try to start ESR and ID.

Cannot connect to server using message server: ms://<XXXXXX>:8100/P4

Details:

Cannot connect to server using message server: ms://<XXXXXX>:8100/P4 (SERVER_MS_NOT_AVAILABLE)

Exception while trying to get InitialContext.

There are no access points for service: P4 registered

on the message server

There are entries for the following parameters in exchange profile.

com.sap.aii.connect.directory.httpport = 50000

com.sap.aii.connect.directory.mshost = <YYYY>

com.sap.aii.connect.directory.mshttpport = 8100

com.sap.aii.connect.directory.name = <YYYY>

com.sap.aii.connect.repository.httpport = 50000

com.sap.aii.connect.repository.mshost = <YYYY>

com.sap.aii.connect.repository.mshttpport = 8100

com.sap.aii.connect.repository.name = <YYYY>

Also I have an entry in the host file:

<IP Address> <XXXXXX>

Could you please tell me if com.sap.aii.connect.repository.mshost should be equal to <XXXXXX>.

Also could you please tell me if I need to check elsewhere aswell.

P.S.

Sorry if its a silly question, I am a developer assigned to troubleshoot this due to other reasons.

Thank you.

Radhika.

Heloo,

This can be issue with Firewall Settings in your Organization.

You need to talk to Network team and get it done by adding the Target server details to ovecome the Firewall Issues

Hi again,

Also you may do the following:

From Control Panel, go to Java -> General tab, Temporary Internet Files

-> View... -> Delete all the content there.

For 7.1 go to:

> Integration buider page http://<host>:<port>/rep

> Administration

> Tab - Directory (Repository as well)

> Java Web Start Administration

> Restore Archives and Generate New Signature

For 7.0 go to:

> Integration buider page http://<host>:<port>/rep

> Administration

> Tab - Directory (Repository as well)

> Java Web Start Administration

> Re-initialization and force-signing

And if you use a High Availability system, check one of the following notes according to your system's version:

#1052984 - Process Integration 7.1 - High Availability

#951910 - NW2004s High Availability Usage Type PI

With regards,

Hello,

Check for the correct message server port on TCODE SMMS

> ms/http_port: 80xx

Also check for the correct RMI port on TCODE SMICM

> P4 port: 50xx0

Please open the Netweaver Administrator and check the Server settings.

Go to Operation Management -> Systems -> Start&Stop -> Java EE Services

-> P4 Provider, check if the P4 service is started and also it should

have the PI host name.

Also, ensure the value for the P4 port: 81xx is open in the firewall

(in both directions).

Concerning the issue, kindly check whether the following HTTP Message

Server port : "com.sap.aii.connect.Repository.mshttpport" in the

ExchangeProfile has the value :

- 81xx where xx is the <SCS-instance number>

Kindly change the following parameters in the Exchange Profile to FQDN:

com.sap.aii.connect.directory.name

com.sap.aii.connect.landscape.name

com.sap.aii.connect.repository.name

Kindly go through the note below to check again:

#773830 - FQHN determination in ICM for details.

If you are on High Availability setup, kindly go through the note:

#1052984 - Process Integration 7.1 - High Availability

and please check if all the parameters are set accordingly.

Also, kindly go through the note:

#1278563 - Specification of message server host in Exchange Profile

It also may be due to a firewall, so please check that out!

Regards,
