Hi Oracle-l team,

We faced the below issue on May mid 2011 and DB was up and running and we thought there is an issue in server itself post SA firmware maintenance. When there was a chance to bounce the server, Database is having hiccups to come up. Is there an option to use Transportable Tablespace? or keep this datafile offline and bring the DB up.
Please lend your advice if there is any sort of recovery.
