Recently when performing performance tests, the developer directly hung all the business tables into the Oracle database because of the space data to be mounted. Several recent tests have found that the response time and throughput are not ideal, after some analysis of the suspect may have problems in Oracle, so I look

Oracle Provide users with an accurate assessment of rollback operation time Are we still in this place? How much longer will it take? Does it sound familiar? These questions may be raised on the way to the children's favorite theme park, from the backseat of the car, and are often raised constantly and frequently. Don't you want to tell them exactly how long it will take-or, more simply, do you know the answer yourself? Similarly, when rolling back

parameters in the process package are optional. The number of disks is not too accurate, so enter an approximate value to make the calibration faster and more accurate. finally in I/O During the calibration process, you can V$io_calibration_status view to view the calibration status. after I/O Calibration is successful, you can see the calibration results in the dba_rsrc_io_calibrate table, in order to better understand I/o The calibration process, we take a normal desktop to carry ou

Comparison of Oracle Database date filtering methods and oracle Performance When developing SQL statements, filtering date segments is a common problem. How can we efficiently filter out date segments? This article demonstrates through experiments: Method 1: Use to_char to convert a date to a string for comparison To_c

problems in the tablespace. Therefore, it is very helpful that each data segment contains only one range. With the help of the monitoring system, you can check the DBA_SEGMENTS data dictionary view to find out which database objects contain 10 or more segments and determine their data segment fragments. If a segment contains too many fragments, you can use either of the following methods: 1. Create a new t

a reasonable parameter value and achieve a balance between the two. After the preliminary adjustment is completed, monitoring is still required later. As enterprise applications change in the future, this parameter still needs to be adjusted according to the actual situation to improve the database performance. 　Ii.
