1. Real-time monitoring alarm log database
as a DBA, or even just dealing with Oracle databases and technical staff, you have to know what is the alarm log, where you are.
As for the DBA, the alarm log real-time monitoring of database work must be done, and should be monitored, depending on severity, different levels of alarm information is sent (via e-mail, SMS), which can help us to keep abreast of changes in the database and abnormal, timely response and intervention process.
2. Real-time monitoring of vital statistics database of
monitoring the implementation of the database for running critical attention to the statistics database that can characterize important changes, and accordingly send alarm information. So what statistics should monitor it? We should distinguish between conditions of deep thinking, different for stand-alone, RAC environment.
Statspack 3. Automated deployment / AWR report generation mechanism
checked daily AWR report the day before, and are familiar with the health of the database, so well known for the database.
4. Top SQL optimization and familiar a day at least
according to AWR or Statspack report, or at least understand a Top SQL familiar with every day, can be optimized to propose optimization and tuning recommendations. DBA should be a stable system for SQL very familiar with and understand, so that they may see around corners in case of system performance issues, make judgments and respond quickly.
5. Deploy comprehensive monitoring and data sampling system
DBA database should be deployed to improve the monitoring system, and important information is sampled in real time or on a regular basis to generate a graph database key indicators show run trend database.
6. The in-depth understanding of application architecture
DBA do not understand the application is no future DBA, the application does not understand the depth of the DBA is not really Expert, so be sure to understand the application.
After the database itself becomes more automated and streamlined, future DBA should continue to move towards the front, to deepen understanding of the application, from the application point of the database and be sure and global optimization.
7. Write system architecture, the status quo, adjust memo
based on a database of research and understanding of the status of the database constantly recording, writing database schema, the status quo and adjust the memo, did not miss any possible optimization and opportunities for improvement.
