Extprocs and the new Exadata server

Question

Our product, Symyx Direct, is a data cartridge. It implements a domain index by means of callouts to an external procedure library.
Customers pose queries such as:
SELECT MOLID FROM MOLECULES WHERE SSS(CTAB,’c=c-c=c@1’)=1;
The table looks like this:
CREATE TABLE MOLECULES (MOLID VARCHAR2(12) PRIMARY KEY, CTAB BLOB);
CREATE INDEX MOLIX ON MOLECULE(CTAB) INDEXTYPE IS C$MDLICHEM60.MXIXMDL;
The indextype MXIXMDL has operators associated with it, including SSS.
The definition of SSS involves extensible index calls to a .DLL (windows) or .SO (unix) that implements the search by calling Oracle OCI routines.
Since external procedures are called by the Oracle optimizer and run as a subprocess of the Oracle shadow task (unix) or thread in oracle.exe(windows) that is running the user’s Oracle session, how would this interact with the new Oracle Exadata Server? Would our cartridge product have to run in each low-level database cell inside the exadata server, or will this run at a higher level?

Answer 1

Anders,
That does not sound to hard ---
I will look into that.
Thanks!
