NLS_CharacterSet update and Standby Databases

NLS_CharacterSet update and Standby Databases

NLS_CharacterSet update and Standby Databases

We have a bunch of databases that use the WE8ISO8859P1 character set. We needed to add the EURO symbol to our Currency setup, but that character isn't supported. The simple solution is to migrate to the WE8MSWIN1252 character set. Oracle has lots of documentation about this and I was able to update a test database in a relatively short time frame. I am confident in what needs to be done and how to do it, but I have a question. We also have a physical and a logical standby database that are updated from our production database. Does anyone know how I should go about updating the standby databases?

Same way as if you would be "patching" the database, check out document id. 278641.1

RE: NLS_CharacterSet update and Standby Databases

For your physical standby, if you are at Oracle or higher, you can change the NLS_CHARACTERSET without recreating the physical standby. This is a new feature of Oracle 11g. The relevant document at support.oracle.com is 1124165.1

For your logical standby, I am quite pessimistic that you will be able to make the character set conversion on your primary database without dropping and recreating the logical standby. See, for example, note 1283764.1, which addresses this issue, although not for the exact character set conversion that you are contemplating.

RE: NLS_CharacterSet update and Standby Databases

Thank you for replying to this thread. I was on a time crunch of sorts and had to plow away with this conversion on the primary database. I ended up deleting both standby's and recreating them. The character set change carried through to the standby creation. It was pretty transparent.

Thanks again
