GoldenGate SQL error 1403 mapping 错误解决方案

故障现象：

2011-09-06 15:45:29  WARNING OGG-01004  Oracle GoldenGate Delivery for Oracle, rora_001.prm: Aborted grouped transaction on 'REALESTATE.JZWFCMS', Database error 1403 ().
2011-09-06 15:45:29  WARNING OGG-01003  Oracle GoldenGate Delivery for Oracle, rora_001.prm: Repositioning to rba 8825466 in seqno 34.
2011-09-06 15:45:29  WARNING OGG-01154  Oracle GoldenGate Delivery for Oracle, rora_001.prm:  SQL error 1403 mapping REALESTATE.JZWFCMS to REALESTATE.JZWFCMS.
2011-09-06 15:45:29  WARNING OGG-01003  Oracle GoldenGate Delivery for Oracle, rora_001.prm: Repositioning to rba 9293635 in seqno 34.
2011-09-06 15:45:29  ERROR   OGG-01296  Oracle GoldenGate Delivery for Oracle, rora_001.prm: Error mapping from REALESTATE.JZWFCMS to REALESTATE.JZWFCMS.
2011-09-06 15:45:29  ERROR   OGG-01668  Oracle GoldenGate Delivery for Oracle, rora_001.prm: PROCESS ABENDING.

问题分析：

出现该问题一般都是由于同步的源和目标表结构不一致，包括表字段和索引。

除表结构外，数据的不一致也可能导致mapping 错误，如原库要delete或update时，gg库找不到该条数据等，具体原因见report中的错误号：

Database error 1403

oerr ora 1403
01403, 00000, "no data found"
// *Cause:
// *Action:

问题处理：

1).如果是表字段不一致，需要修改表字段，，异构数据库还需要重新生成表结构定义文件，再重启进程。

2). 如果是索引不一致，需要重建索引，异构数据库还需要重新生成表结构定义文件，再重启进程。(之前没有关注索引是否一样，以后关注一下索引)

3). 遇到这种情况，不能先去对比两端的表结构（可能修改表结构的sql在后面执行），而应该先去查明原因。若是数据问题，可以跳过该表的同步，然后重新同步该表。

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
