Upgrade Dataguard 9.2.0.8 (32-bit) to 10.1.0.5(64-Bit)

What is the best way to do this with minimal downtime. I have two (2) machines [the two 32-Bit] primary (9.2.0.8) and Eve (9.2.0.8)... I need to switch the primary and standby to 10.1.0.5 (64-bit) to new hardware, limited service disruption. I'll have the new machines built and installed with 64 - Bit. My question is: can I have a computer 32-bit archlogs sending to a 64-Bit machine to apply (Dataguard)? My thought was to have the original upgraded to 10.1.0.5 (32-bit) 32-bit machine (9.2.0.8) Firstly build a Dataguard on one of the new 64-Bit machines and ship the new machine until the changeover weekend newspapers. I read a few posts that I can have a 32-bit database running on a 64-bit computer (with just the RPM 64 - Bit and 64-Bit o/s installed), deliver the newspapers to the Machine 64 - Bit, and then failover weekend change the wordsize of 32 bit to 64 bit, but don't know how true that is. Any help would be greatly appreciated

I agree with FZheng, you should consider Oracle 11.

You can avoid a database bounce by putting in place all your new settings Data Guard and FRA beforehand. And you can use an alter system to change the LOG_ARCHIVE_DEST_STATE_2 of "reporter" while you use RMAN duplicate to create the day before.

So to build the new system, but add these settings even before starting the data move from Oracle 9.

FAL_SERVER
FAL_CLIENT
STANDBY_FILE_MANAGEMENT=AUTO
DB_UNIQUE_NAME
DB_FILE_NAME_CONVERT
LOG_FILE_NAME_CONVERT
log_archive_dest_1
log_archive_dest_2
LOG_ARCHIVE_DEST_STATE_1
LOG_ARCHIVE_DEST_STATE_2
LOG_ARCHIVE_MAX_PROCESSES

Create your spfile on the primary with LOG_ARCHIVE_DEST_STATE_2 set to ACTIVATE and you avoid a stop and restart later. Then change to DELAY until you build the day before. You can save time more by copying the password in advance. Wait to issue the FORCE LOGGING until all the data is transferred.

Place your tnsnames and the Auditor including _DGMGRL on both servers in advance.

If plan you correctly, you can use RMAN two copies and never primary stop. The day before will just begin to apply again them.

If you find this "Helpful" Please mark as well.

Best regards
