Emptying the Oracle Recycle Bin in Oracle 10g Release 2

Thu, 04 Jan 2007 00:00:00 +0000

Empty Oracle Recycle Bin

A new feature in Oracle 10g Release 2 was the Reycycle Bin. The recycle bin in the Oracle database is where all dropped objects reside. Underneath the covers the object are taking up the same space when they were created.

"DROP TABLE mytable", it doesn't really drop it. It instead renames it to e.g.: BIN$67815682942.

Dropped objects are not deleted they are just rename with a prefix of BIN$$. One can get access to the data in a dropeed table or even use a Flashback Query if you have this feature enabled on your version of Oracle.

Relink Oracle Database Software on Unix Linux RAC Cluster

Had problems with running Oracle RAC on a cluster on Redhat Release 3 AS. So we started the conversion to Redhat Release 4 AS. We run a 2 node RAC Cluster on iSCSI Lefthand Networks SAN. The Oracle software is installed on a lun on each machine and the database is on lun’s of RAW disk manged by ASM. This allows flexability by moving the luns from OS to OS and recompiling the Oracle binaries when we need to move the Oracle Cluster to a new version of the OS.

Oracle RAC Standard Edition Installation Planning

Started planning new Oracle database using Oracle 10g RAC Standard Edtion. It has been interesting so far. Running Linux Red Hat AS 3.0 and data is being put out on a LeftHand Networks SAN.

Configured the SAN and NSM to layout disks. Than used ISCSI drivers to connect the SAN Lun’s and Linux togather so we could stat building Oracle RAC. The hardest thing to come to terms with for Oracle 10g RAC Standard Edition is that the require the use of Oracle Automatic Storage Manger or Oracle ASM.
