ORA-14300 分区键映射到超出最大允许分区数的分区”

Question

在 IDR 9.6.3 HotFix 1 中运行 Applier 将数据加载到 Oracle 目标时，将分区添加到目标表后\n问题描述

\n\n

将 INTERVAL 分区添加到目标表列后，Informatica Data Replication (IDR) 应用程序进程无法将数据插入到目标，并出现 Ora-14300 错误。

\n\n

分区详细信息：

\n\n

PARTITION BY RANGE ("column_name") INTERVAL (NUMTODSINTERVAL(1,\'DAY\')) \n

\n\n

记录错误的 Applier 日志如下：

\xe2\x80\x8b\n原因

\n\n

出现此问题的原因是创建分区条件的列是在 IDR 中创建的虚拟列，并且该值是使用 SQL 表达式更新的。它不是源自来源的专栏。

\n\n

使用虚拟列时，Applier 首先插入物理列，然后使用基于物理列计算的值更新虚拟列。

\n\n

因此，分区列首先插入 NULL 值，这会使分区条件无效并导致 Oracle 错误\xe2\x80\x8b。

\n\n

解决方案\n若要解决此问题，请执行以下操作之一：

\n\n

Drop the current partition and use a different column [not a virtual column originated from IDR] as partition key and restart applier task.\n

\n\n

或者

\n\n

Based on the SQL expression being used to update the virtual column value, alter the column to include a DEFAULT value. Thus, on insert, the default value will be inserted first and the update will apply the value from the SQL expression.\n

\n\n

您需要为表启用行移动，以便在 Applier 发出后续更新时将该行移动到适当的分区。

\n

Answer 1

发生此异常的情况之一是您尝试插入的记录中的分区键为空。
