数据库升级到19后，大量的 ORA-3137[kpoal8Check-5] 错误

郑全

数据库从11G升级到19C后,报警日志中不停的报这个ORA-3137的错误，

如下：

。。。

ORA-03137: TC : [kpoal8Check-5] [0] [0x000000000] [0x000000000] [0] [0] [265512] []

。。。

TRACE文件中，包含：ksedst1,ksedst,dbkedDefDump,ksedmp,dbgexPhaseII,dbgexProcessError,dbgePostErrorKGE,dbkePostKGE_kgsf,kgeade,kgerelv,opiierr,kpoal8Check ,kpoal8,opiodr,ttcpip,opitsk,opiino,opiodr,opidrv,sou2o,opimai_real,ssthrdmain,main,libc_start_main

这个主要是客户端版本和数据库服务器版本不匹配导致的，有些客户端版本还是8I,9I，

解决办法：升级客户端到11.2.0.4以上版本即可.

The Call Stack Trace in the associated incident trace file shows:


opiierr <- kpoal8Check <- kpoal8 <- opiodr <- ttcpip <- opitsk <- opiino <- opiodr <- opidrv <- sou2o



CHANGES
The database was upgraded to 12.2.


CAUSE
This issue is caused by the client version not being compatible with 12.2 RDBMS server version.  Unlike previous versions, Oracle has added some strict checks in 12.2.0.1 and client applications must comply with these checks.


This issue was investigated in unpublished Bug 26092744 which was closed as Not a Bug.



SOLUTION
Upgrade the client to a compatible level.
