HOW TO: Analyzing and Interpreting AWR Report
Hello
Today I wanted to share with you my personal approach for how to get into the details on AWR Report and where to see and where should be our attention. Keep in mind just two main focuses : the Application and the Database instance
1) Application: Most of the times you should go directly to review how was the SQL statements Performance. That is MANDATORY and the result of your analysis will be the classic TOP 10 SQL with the worst performance. That should be called : Oracle Application’s Performance Tuning .
2) Instance: read once, twice or three times the AWR looking for issues. What kind of issues or metrics ?
For example here I have a Conclusion and Workaround for one database instance issue regarding performance :
1) Tuning recommendations for PROD-ACME database instance:
AWR Report – How to get it through EM
We need a database user/pwd
….
But we can generate it using SQLPLUS as well :
AWR Snapshot Reports
Oracle provides reports that you can run to analyze the data in the AWR. These reports are much like the statspack reports prior to Oracle Database 10g. There are two reports: awrrpt.sql and awrrpti.sql, which are available in the directory $ORACLE_HOME/ rdbms/ admin.
The output of these reports is essentially the same, except that awrrpti.sql script allows you to define a specific instance to report on. The reports are much like the statspack reports of old, in that you define a beginning and ending snapshot ID, and the output filename of the report. Additionally, you can opt to produce the report in either text format or HTML format.
[oaPROD usa.com01 PROD] $ sqlplus ‘/as sysdba’
SQL> @awrrpt.sql
Current Instance DB Id DB Name Inst Num Instance
HOWTO: Checking options installed within the Database/Oracle Home
1)From Oracle Universal Installer: In OUI select installed products and click on list and expand, you will see a list of options installed in database.
You have to use OUI to check whether Oracle Secure Enterprise Search is installed or not.
TIP: Start Oracle Universal Installer from your system prompt (UNIX) with the following command:
./runInstaller
2)From v$option:
SQL> set pages 100
SQL> select * from v$option;

Forms in socket mode
Algun cliente alguna vez debe haber sufrido de un extraño issue con los forms y se preguntara si vale la pena cambiarlos a ‘socket’ mode, y él se estará preguntando (con toda razón):
A. When the forms are changed to socket mode:
1. Will this affect the EBS application in anyway (will it be slow than now)
2. Do we need to perform any change on our or the workstation’s side ?
ASSESSMENT AND SOLUTION
Please look at the Note in Metalink 310976.1. It seems that the Java Console in JInitiator tells you at the beginning which mode you are using.
Verifying the Forms Client Connection to the Forms Server
Once the Applet has initialized and started, it connects to the Forms Listener, using the serverPort, serverHost and connectMode parameters displayed in the Java console. Steps to verify this are:
HOWTO : Getting User Responsability on EBS 11i using a Database user (BOLINF or APPS)
Find below the SQL statement to generate an extract with active users together with their active responsibilities.
The statement extracts all the active assignments of responsibilities by using the FND_USER_RESP_GROUPS table which combines DIRECT and INDIRECT responsibilities.
If you need only the DIRECT responsibilities than you also have the option to use the seeded view FND_USER_RESP_GROUPS_DIRECT. If you need only the INDIRECT responsibilities (added by roles – like Application Diagnostics and others) than use the seeded view FND_USER_RESP_GROUPS_INDIRECT.
As always adjust the SQL to cover your needs.
SELECT
fuser.USER_NAME USER_NAME
, per.FULL_NAME FULL_NAME
, per.EMPLOYEE_NUMBER EMPLOYEE_NUMBER
, frt.RESPONSIBILITY_NAME RESPONSIBILITY
FROM
FND_USER fuser
, PER_PEOPLE_F per
, FND_USER_RESP_GROUPS furg
, FND_RESPONSIBILITY_TL frt
WHERE
fuser.EMPLOYEE_ID = per.PERSON_ID
AND fuser.USER_ID = furg.USER_ID
AND (to_char(fuser.END_DATE) is null
OR fuser.END_DATE > sysdate)
AND frt.RESPONSIBILITY_ID = furg.RESPONSIBILITY_ID
AND (to_char(furg.END_DATE) is null
OR furg.END_DATE > sysdate)
AND frt.LANGUAGE = ‘US’
ORDER BY
, fuser.USER_NAME;
Ramakrishnan & Gehrke Sailors script for Oracle database
The chapter 5 of the book “Database Management Systems” (Ramakrishnan, Raghu & Johannes Gehrke.) introduces the Sailors data model, a set of three tables named Sailors, Boats and Reserves
In this article, the SQL script that implements the creation of these relational structures is developed and adapted for Oracle Database. This script is based on the script worked by Hjalmtyr Hafsteinsson for PostgreSQL database.
The script does the following tasks
Cleans Sailors Schema and tablespaces of previous script executions
Creates Sailors_data and Sailors_index tablespaces
Creates Sailors Schema
Grants roles and privileges to Sailors user
Connects to Sailors user
Creates tables, constraints, in the Sailors Schema
Populates tables
Adds new columns and new constraints (that are not part of the original data model)
Creates B-tree indexes for columns that are used in WHERE clause
Cambiar logfile del Listener sin tener que detenerlo
Hay veces que el log del listener crece sin parar y puede llegar a pesar varios GB . Una solucion para esto es detener el listener, truncar el archivo y volver a levantarlo, pero hay veces que las base de datos son 24/7 y esta solucion no sirve .
La solucion que voy a postear es una de las muchas que encontre en este link : http://msutic.blogspot.com/2009/06/truncating-rotating-flushing.html
La solución que implemente fue en un Oracle 10.2.0.5 y consistia en crear un nuevo log para el listener por cada mes del año con el siguiente formato :listener_yyyymm.log , asi cada mes del año iba a tener su propio log.
Estos son los pasos :
1) Conectarse con el utilitario LSNRCTL y setear el listener actual (Por lo general el nombre default es LISTENER)
C:UsersJCAJ>lsnrctl
LSNRCTL> set current_listener LISTENER
Current Listener is LISTENER
Paquete LT_CTX_PKG inválido (9.2.0.8)
El otro día revisando los objetos inválidos del SYS de una BD Oracle 9.2.0.8 me encontré que el paquete LT_CTX_PKG estaba inválido por que había un código no identificado dentro del BODY de este.
