Connect to Gateway Failed during database instance installation

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

FRF-00007 Unable to open RFC connection.

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.

Dennis
