DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: PHKL_44155

* 3542231 (Tracking ID: 2203917)

SYMPTOM:
The I/O performance for Oracle Disk Manager (ODM) is poor.

DESCRIPTION:
The I/O performance for ODM is due to a lock contention on the odm_iop_table. 
The odm_iop_table maintains a structure for each process performing I/O 
operations via ODM.

RESOLUTION:
The code is modified to increase the number of hash buckets from 32 to 256. 
This reduces the contention on the global lock.
