Change 32bit 11.1.0.7 to 64bit on same Windows host w/standby databases
Situation: ServerA: Windows 64bit OS/hardware; 64bit 11.1.0.7 software; Primary database
ServerB: Windows 64bit OS/hardware; 32bit 11.1.0.7 software; 2 Standby databases
Goal is to have ServerB using 64bit 11.1.0.7 software. I've referenced Docs: 817715.1, 548978.1 and 62290.1. I'd like to keep the standby databases active as much as possible and change them one by one or all at once. I can install the 64bit 11.1.0.7 software into a new Oracle Base/Home on ServerB, but I'm concerned there'll be problems with a second listener being created with the 64bit 11.1.0.7 software install? Won't there be conflicts with default listening ports, incoming connections? Or, does the install use a different port versus the default 1521? I also don't believe STARTUP UPGRADE is doable
