Oracle 11g Release 2 | Generating tablespace details takes long time to complete

Hi guys

Recently we migrated our database from 10gR2 (10.2.0.3) to 11GR2 for our EBS environment and got stuck with a new issue, the tablespace details take hours to get generated (Regardless the clients used, SQL Developer/Toad or SQL scripts)

Then we came across a post here about “recyclebin”. At the 1st instance, purging the recyclebin did work(?), yet the delays were significant. Further references landed us to this page

By following the instructions, as sys we purged “dba_recyclebin” which was having approximately 262 objects and voila! The database started generating the tablespace details within a fraction of second.

Hope this helps few others out there!
