Performance appraisal is made to work on a number of employees, consider quantify the quality, difficulty, strength and efficiency. Due to the nature of the DBA pure R & D personnel or maintenance staff differ on KPI assessment indicators DBA also has its particularity. Reference to past experience and some of the larger DBA team (such as Alibaba more than 80 DBA team) approach, the performance of a DBA's roughly assessment from the following four aspects:
First, the high-availability database (weighted 30%)
1. To maintain high availability database DBA is one of the most important responsibilities. Because every failure will bring great loss to the organization, the vast majority of online systems are required to provide 24 * 7 services.
2. annual evaluation, for example, may be responsible for a DBA database availability score 1-5 points:
3. Database availability of 99.999% (in no more than five minutes of downtime), 5 points;
4. Database Availability 99.99% (downtime of less than 30 minutes), 4 minutes;
5. the annual total downtime than half an hour, in principle higher than 3;
6. omission caused an outage due to work more than 10 minutes a serious fault, this score the <= 2.5;
Description:
1. database availability standard of 99.99%
2. affect the availability of events include: important business can not access critical business error, the access speed is very slow seriously affect the customer experience event

4. the investigation and analysis of system performance, providing valuable database analysis, and implementation of relevant tuning scheme
5. attention analysis, reduce the number of daily warning: warning reduced to 15 per week, five critical week
6. unexpected events occur can handle
7. ready to carry a mobile phone, is turned on to maintain 24 × 7
