    • Hello,

      As I understand it :

      - You "synced" your db in 10g right before upgrading the rdbms and dictionnary on your primary.

      - You installed the binaries on the primary and played the dbua script on your primary. This lead to generating archived log.

      - You installed the 11g binaries on your standby db.

      The next step would be to set the environment variables on your standby db to use 11G binaries.

      Then you copy the "dbua" generated archived logs to your standby and restart the "recover managed standby database" in order to get them back in sync on 11g.

      Best regards,
