Unable To Set Db_file_multiblock_read_count Parameter To Zero (Doc ID 1153666.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.1 to 10.2.0.3 [Release 10.2]
Information in this document applies to any platform.
***Checked for relevance on 22-Sep-2016***

Symptoms

Configuring db_file_multiblock_read_count=0 does not enable the Self-Tuning Multiblock Read Count feature and incorrectly results in a value of 1.
This conflicts with the documented behaviour of this parameter.

Changes

db_file_multiblock_read_count was set to zero dynamically.

SQL> alter system set db_file_multiblock_read_count=0 scope=memory;

[reconnect]

SQL> show parameter db_file_multiblock_read_count

db_file_multiblock_read_count is set to 1 for new sessions
