文档解释
ORA-24797: cannot promote the current transaction to a distributed transaction
Cause: An illegal attempt was made to promote the current transaction.
Action: Verify that OCI_ATTR_XID, OCI_ATTR_INTERNAL_NAME, and OCI_ATTR_EXTERNAL_NAME attributes have been set properly, and verify that the current transaction has neither performed IDL or PDML operations, nor already been a distributed transaction. Also, verify that the local transaction is in the same isolation level if the isolation flag value is set.
ORA-24797错误表明:当前事务无法提升为分布式事务。
官方解释
常见原因:
1、当前事务可能已经被提升为分布式事务;
2、可能是由于不支持的应用程序(如联机查询语言)下访问数据库时引发;
3、由于分布式事务操作(如分布式事务状态检查失败)可能会引起;
4、也可能是由于路径连接特性(特定的连接特性)导致。
一般处理方法及步骤
1、确认当前是否已经被提升为分布式事务;
2、检查表空间是否有足够的空间;
3、重新分配路径连接特性;
4、重新确认应用程序操作;
5、分析数据库的事务日志;
6、启动备份数据库,进行数据库分析。
