ORA-14015: too many partition descriptions ORACLE 报错 故障修复 远程处理

文档解释

ORA-14015: too many partition descriptions

Cause: CREATE TABLE or CREATE INDEX contained too many partition descriptions; maximum number of partitions is 1048575 (1024K-1).

Action: Reduce number of partitions to not exceed 1048575 (1024K -1).

ORA-14015：太多分区描述

这是一个Oracle数据库报错，代表在一个DDL语句中的分区描述的数量超过了允许的限度。

官方解释

ORA-14015: “too many partition descriptions”

Cause: A partitioned object statement had too many partition descriptions. The limit is 255.

Action: Reduce the number of partition descriptions in the statement. If you want more than 255 partitions, use GLOBAL indexes or subpartitioning.

常见案例

此错误常常由DDL语句中提供的分区数量过多引起，比如下面这个语句：

CREATE TABLE T1

PARTITION BY RANGE (col1)

(PARTITION p1 VALUES LESS THAN (1),

PARTITION p2 VALUES LESS THAN (2),

PARTITION p3 VALUES LESS THAN (3),

PARTITION p4 VALUES LESS THAN (4),

PARTITION p5 VALUES LESS THAN (5),

…

)

正常处理步骤

1.确认分区描述数量是否达到了限度（最多255个）。

2.如果需要更多分区，可以使用GLOBAL索引或子分区。

3.如果分区数量达到了最大数量，可以将原有的分区拆分成多个小分区，减少分区描述数量。
