在上周,由于交易量非常大,发现part_max分区已经开始进入数据了,并且进入的数据量还不小,有大概3个partition的数据。担心大量数据进入part_max分区引起业务查询缓慢,于是决定实施split part_max分区,split执行的语句为: ALTERTABLEtest01 SPLIT PARTITION part_max AT(1000)INTO(PARTITION part_1000,PARTITION part_max...
Elapsed为该AWR性能报告的时间跨度(自然时间的跨度,例如前一个快照snapshot是4点生成的,后一个快照snapshot是6点生成的,则若使用@?/rdbms/admin/awrrpt 脚本中指定这2个快照的话,那么其elapsed = (6-4)=2 个小时),一个AWR性能报告 至少需要2个AWR snapshot性能快照才能生成 ( 注意这2个快照时间 实例不能...
在12c中新增强的SPLIT PARTITION 语句可以让你只使用一个单独命令将一个特定分区或子分区分割为多个新分区。下例说明了如何将一个分区分割为多个新分区: 复制 SQL>CREATETABLEemp_part(eno number(8), ename varchar2(40), sal number (6))PARTITIONBYRANGE (sal)(PARTITION p1VALUESLESS THAN (10000),PARTITION...
These errors often manifest themselves as PL/SQL parser or execution errors pertaining to blocks of PL/SQL code embedded within application components. The installation process sometimes splits strings greater than 200 characters into multiple lines. For example, lines may split between PL/SQL keywords...
