Patch install and SYSAUX tablespace fixes

RDBMS 11.2.0.2, Linux 64-bit.

I just applied patch 14373728 and all went well despite nagging errors in the postinstall.script ("SET PAGESIZE 0", and the role "gather_system_statistics" conflicts with another user or role name).

Probably shot myself in the foot dropping the "gather_system_statistics" role and re-running postinstall.sql, but that is yet to be seen.

So, I have 40 million rows to clear out of WRI$_OPSTAT_HISTGRM_HISTORY, and I'd like a "best practice".  Here's what I think will work:

1) take a metadata only datapump export of the SYSAUX tablespace

2) shutdown the database and bring it up restricted

3) offline the tablespace, and move the datafiles out of the way
