Connect to Gateway Failed during database instance installation

[Former Member]

Hi All,

I install Netweaver 2004 (6.4) ABAP stack.

I've finished the installation of oracle 10.2 and central instance. During the installation of database instance, an error happens when "starting RFC jobs".

In the logviewer:

ERROR 2007-07-02 18:37:14

About my installation environment:

Windows XP

I've enlarged the page file size before installation.

I've looked up the info from Internet, so I've checked the following:

Under \system32\driver\etc\hosts

10.10.10.10 <domainname> <hostname> is configued as a loopback address (I was prompted to use loopback adapter when installing Oracle, because my network adapter uses DHCP)

Under \system32\driver\etc\services

sapgw00 3300/tcp # SAP System Gateway Central Instance Port

sapgw00s 4800/tcp # SAP System Gateway Security Port

I can ping 10.10.10.10 (get response)

(Any possibility that the installation user can not access 10.10.10.10:3300 ??, I don't know.)

However, I can't logged on the system, because in the MMC, "disp+work.exe" turns yellow(Dialog Queue standstill) and then becomes gray.

Some experts in some forums have commented that a long hostname (>8 characters) might be the problem. Is it true?

(I've not installed the standalone gateway instance yet. ) When do I need to install the gateway instance? Now, I installed as follows: DB software->Central Instance->DB instance.

Thanks in advance.

Hi,

I had a similar error, when installing SAP BW 3.1. on windows 2000 advanced server, oracle 9.2.0.6.

FRF-00007 Unable to open RFC connection.

ERROR 2006-12-04 07:03:21

FRF-00063 RFC logon failed with message: Failed……………………………………

However this holds good for NW 2004 also.

To resolve this error you will need to upgrade your SAP kernel level.

1) Download the kernel. i.e. sapdbexe.sar and sapexe.sar.

2) uncar the files sapdbexe.sar and sapexe.sar using the sapcar.exe

On dos prompt go to the particular directory where u have downloaded the above sar files using "cd" command.

3) To Uncar the files use this command on dos prompt

SAPCAR -xvf <your-SAR-file> to uncar the files.

4) shut down sap using the MMC.

then in windows services.msc stop saposcol ,stop oracle service sapserviceSID and and the sapSID_##

5) Now just copy the new kernel files you have uncared above into the /usr/sap/SID/exe/run/ directory of your system

6) Start the services you stopped and start SAP using the MMC.

Now you should be able to logon. Sometimes the MMC shows the yellow status due to missing workprocess status. However the system should work fine.

Hi Manmath,

My installation is NW2004.... SO the kernel is 6.40,

If I update the kernel, which edition should I update? 7.0 ?

Thanks

Hi Dennis

For (any) Basis release 6.40, you MUST use kernel version 6.40. The same thing should be used for 7.10, ie only use 7.10 Kernel version.

Do not mix Basis releases with diferent kernel versions.

Hi,

you can't ping port (from Windows) but you can try to telnet it (i.e. telnet 10.10.10.10 3300) If port is closed apriopriate message should be displayed.

Check this port if it is "telnetable" first.

Hi Filip,

"Could not open connection to the host. on port 3300: connect failed".

Why telnet on this port?

3300 is used for the rfc communication, I'm correct? What does this problem mean?

Any suggestions?

Thanks

Hi all,

During the installation of DB instance, should the gateway service start? If I'm correct, dispatcher is responsible for the startup of gateway process. If the dispatcher is not started, will the gateway start? If not, the gateway service will not accessible. I'm right?

PS: in my Windows XP OS, port 3300 is not listed in the "netstat" results.

It seems sth is wrong when starting the instance. (dispatcher and work process can't start properly)

Any good ideas? Thanks.
