O que o ADRCI pode me ajudar: A ferramenta essencial para gerenciar erros do banco de dados Oracle

O que o ADRCI pode me ajudar no meu dia a dia ?

Introduzido no Oracle 11.1.0.6 o ADRCI (Automatic Diagnostic Repository) é uma ferramenta desenvolvida pela própria Oracle que ajuda o DBA a gerenciar os erros que são gerados pelo o banco de dados. Além de visualizar os erros, podemos até mesmo definir uma janela de expurgo de traces sem a necessidade de criarmos um script na crontab ou job interno do Oracle.

Para utiliza-lo não há segredo, ele já vem instalado, basta executar:

[oracle@marte ~]$ adrci

ADRCI: Release 12.1.0.2.0 - Production on Mon Oct 19 17:52:17 2015 

Copyright (c) 1982, 2014, Oracle and/or its affiliates.  All rights reserved.

ADR base = "/u01/app/oracle"

Com as variáveis exportadas ele irá se basear no seu ORACLE_BASE para encontrar ORACLE_HOMES que possua utilizar:

adrci> show homes

ADR Homes:

diag/clients/user_oracle/host_1710563632_82

diag/rdbms/orclp/ORCLP

diag/tnslsnr/marte/listener

diag/tnslsnr/marte/listener_02

Selecione o home desejado:

adrci> set home diag/rdbms/orclp/ORCLP

O comando show alert faz o mesmo que um vi alert_ORCLP.log faria:

adrci> show alert

ADR Home = /u01/app/oracle/diag/rdbms/orclp/ORCLP:

Cria um IPS (Incident Packaging Service) com base em um incidente específico para ser usada em uma SR na Oracle.

adrci> ips create package incident 185


Created package 1 based on incident id 185, correlation level typical

Cria um IPS para todos os incidentes

adrci> ips create package

Created package 2 without any contents, correlation level typical

Cria um IPS para um determinado período, esse é útil quando ocorrem vários erros facilitando a criação do IPS rapidamente sem ter que criar um por um:

adrci> ips create package time '2015-10-10 00:00:00 -03:00' to '2015-10-19 22:00:00 -03:00'

Created package 3 based on time range 2015-10-10 00:00:00.000000 -03:00 to 2015-10-19 22:00:00.000000 -03:00, correlation level typical

Cria um IPS em um determinado diretório:

adrci> ips generate package 1 in /home/oracle

Generated package 1 in file /home/oracle/ORA4031_20151019181428_COM_1.zip, mode complete

Cria uma IPS com base em um problem key
