Install new Dialog Instance on 64-bit Server with 32-bit database

I need to set up a new Application Server for our current ECC 5.0 32-bit Oracle Non Unicode Database. The new server is x64-bit and will have Windows 2003 64-bit OS. I am reading SAP notes 785888 and 814834 and need help understanding how exactly to do this. The database server is 32-bit Windows 2003 and so is all the other application servers. Do I use the Oracle 9.2.0 client for 32-bit Oracle and do I use the SAP ECC X64 Install Master in setting up the dialog instance or do I use the 32-bit Install master? Has anyone done this type of setup before? Thanks.

    Thanks so much for the information. I have another question concerning this process. Note 785888 says all application servers must run a kernel at the same patch level. If my 32 bit application servers are at kernel patch 221 then the new 64 bit application server also needs kernel patch 221 except it needs the 64 bit version. Am I understanding this part correctly? Thanks for your help.

      Thank you for your help with this. I have accomplished installing the new application server connected to a test 32-bit database.

    all basic information is provide in note 785888.

    you want to install dialog install on 64bit windows for 32 bit central instance for that you should consider following.

    -> file system is accessible from both host vice a versa for that you can create one use sapinst on 64 bit host with administrator authorization. and create same user on central instance with administrator authorization and same password.

    -> perform dialog instance installation using this user ( i.e sapinst)

    -> if you want to use dialog instance on 64 bit host with 64 bit kernel, install oracle client 10.2 for 64 bit on 64 bit host of windows. for media information check note 949116.

    ->use non unicode kernel because central instance use non unicode kernel.

    -> most important 64 bit dialog instance required 64 bit kernel, SAPinst installation screen ABAP System > Instance Directories, where you are asked for the "Location of SAP System Executable", you choose "Yes, locate executables on central instance host", before choosing "Next". The executables for the dialog instance are installed to


    so when you want to apply kernel patch you have to uncar the kernel package to this location.

    -> maintain the kernel patch level same on both host.
