Connect to Gateway Failed during database instance installation

Question

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.
