The Problem
===========
The longer you've been working as a DBA, the more you've encountered things like these:

The time on a table changed and you don't remember doing it. You poke around but can't figure out who changed it.

There's someone you don't trust that you have to give access to. They are the kind of person that will look at things they are not supposed to, but you have to give them access.

There's someone who always messes things up when they get access. You know they'll do it again and you'll have to undo the damage. Would be nice to know what they are doing.

There's a contractor or a new employee that need access. You don't know them yet and not sure how reliable they are. It would be nice to be able to keep an eye on them.

Too many people have too much access and you're losing control. You try to figure out how to reduce the access they have or revoke some privileges, but this is pretty much what everyone claims they need to do their jobs.

You've been through an audit and the auditor wanted to know all sorts of things about the activity. Questions you just don't have the information needed to answer.

You probably spent many days chasing down the answers to these questions or try to find ways to collect it. The security in the database is set properly. The problem is that you need to know what people are doing with the access they have. This knowledge will give you more control.

Performance Improvement in Pro*C

Pro*C code compilation builds executable depends on the parameters passed while compiling a code on Linux OS. GCC compiler is widely used for compilation.

Parameters that it provides enables memory management and linking etc...
This means : Without changing Code GCC compilation parameter change can give significant improvement in performance without impacting functionality. Attached document contents details study of the same.

This document gives details about environment,deployment and pre-post change analysis.

If you moved to BI Publisher 11g or OBIEE 11g from BI Publisher 10g, you would have realized that debug option is no longer part of BI Publisher Administration UI. In 10g we can set the debug log level from Administration UI under Server configuration section but in 11g no more.In OBIEE 11g, it is central logging process which is part of Fusion Middleware.

Yesterday I am importing some table data in non production database using Datapump utility.

ORA-22804: remote operations not permitted on object tables or User-defined type columns

Restriction on Using User-Defined Types with a Remote Database:

One of my application team lead called me... Raja, we have faced DB link issue while accessing the table from remote database.

“While accessing the table from remote database & they got the below error”

ERROR at line 1: ORA-22804: remote operations not permitted on object tables or
User-defined type columns

I have verified the database link & its working fine.

Colored SQL in AWR report:

AWR captured all the SQL which was running in database?

No.

MMON captured only top resource consumed queries based on
STATISTICS_LEVEL parameter and dbms_workload_repository.modify_snapshot_settings topnsql variable value.

I want to capture some sql in AWR report.

CONVERTING PHYSICAL STANDBY DATABASE TO SNAPSHOT STANDBY DATABASE

Step 1: Check if Flashback is enabled.

Introduction

Oracle Grid Infrastructure 11.2.0.2 has many features including Cluster Node Membership, Cluster Resource Management and Cluster Resources monitoring. One of the key area where DBA need to have expert knowledge on how the cluster node membership works and how the cluster decides to take out node should there be a heart beat network, voting disk or node specific issues. I have written about this before and this article specifically focuses on the 11g R2 features and I will also try to explain the reboot less node fencing.

Steps to create standby database using RMAN:

primary database name:taurus
host name:sony
db_unique_name=production

standby database name:taurus
hostname:sonydr
db_unique_name=standby

Oracle 10.2.0.1.0
RHEL 4
-force logging is enabled on the primary database.
-password file is created for primary database
-primary database is in archivelog mode
