add the line:

sapgw00 3300/tcp # SAP System Gateway Port

To the File C:\WINDOWS\system32\drivers\etc\services.

Victor,

In your case it would be sapgw90 3390/tcp # SAP System Gateway Port

I think this should be present but still you can cross check it.

i go to "Content Maintenance", select "Application System Instance", i select the application that want change the ip, in the top select the "Associated Instances", select "Application System Instance Host", select the "Antecedent" that i want change the ip and now can change the ip...

[Former Member]

[Former Member]

machine

[Former Member]

Hi,

To the best of my knowledge a update in services file does not require a restart as all requests are checked in the service file every time.

Please try this from the portal server try to ping the R/3 system.

ping 192.168.101.250

Thanks & Regards,

The ping work perfectly...

[Former Member]

Hello,

Remove multiple sapmsCER entries in the services file.

Also check the ip of your R/3 system say XXX.XX.XX.XX

Then add in hosts file of the portal server

XXX.XX.XX.XX hostname

hostname is the name of your R/3 machine

Try again.

Thanks & Regards,

Anybody?????

[Former Member]

Hi Victor,

Your entries in services file are correct.

While configuring JCO just check if you are using correct client and system number.

How can see the client and system number?

[Former Member]

Victor,

open your SAP Logon pad and select the system for which you want to know the system number and click on change item button. From here you can see the system number of that particular system.

While you login to this system you would get client number at the top on your logon page itself.

Victor,

I guess your double entries for sapmsCER & sapgw90 is the error.

this should be the only entry for sapgw90:

sapgw90 3390/tcp

and this the only entry for sapmsCER:

sapmsCER 3690/tcp

kr, achim

[Former Member]

How can know if is sapgw90 or sapmsCER...???

[Former Member]

Hello,

Logon to the R/3 system from where you are trying to retrieve data.

Open Transaction ST11

Open the file dev_ms.

There will be a line <b>I listen to port sapmsXXX (36xx)</b>

Open the services file in the portal system and add the entry

sapmsXXX 36xx/tcp

Thanks & Regards,

Hi Victor,

Please check if you have made entry in drivers\etc\services file of server.

If you still get an error....may be your R/3 system for which you are making entry is down.

Smruti

I have in the services this:

sapmsCER 3200/tcp

sapmsCER 3903/tcp

sapmsCER 3690/tcp

sapmsCER 3600/tcp

sapgw90 3690/tcp

sapgw90 3390/tcp # SAP System Gateway Port

sapgw90 3600/tcp # SAP System Gateway Port

sapgw90 3903/tcp # SAP System Gateway Port

R3 no is down, because i´m in it...

[Former Member]

U need to do the following things

1) make entries in the services file in your server Dir. path -> c:\WINDOWS\system32\drivers\etc\services

sapmsDE1 3390/tcp # SAP System Gateway Port

Check your message port number with your R/3 Basis Admin.Default is

36[instance number]

2)And also in host file

R/3 IP Addr R/3 Server Host Name # SAP R/3 System

for ex:

192.168.40.71 PRODNET # PRODNET System Network IP

3) add the portal IP and host name in

\WINDOWS\system32\drivers\etc\hosts

192.29.10.0 Poratal host

[Former Member]

1) I check the port number with the transaction rz70, in msgsrv and press test, it´s good? The port is 3690.

2-3) In host file... i have...

127.0.0.1 localhost

192.168.101.250 clariana.grupotec.local

192.168.101.251 clarianades.grupotec.local

192.168.100.41 netweaver

good?

[Former Member]

yeah it looks good

[Former Member]

ot of thanks, appear: "I listen to port sapmsCER (3690)"
