案例： 修复Oracle 11.2.0.1 dblink 访问ORA-600 [2252]
2019.6.23 已过去，默认11.2.0.3 后的版本Compatibility 已auto Auto-rollover，开始解决方法还要大版本升级，目前Oracle 又陆续放出了几个低版本的opatch， 修复ORA-600 2552不用再大版本升级，目前opatch 已经从10.2.0.4以后的版本都可以装one-off patch解决。更多信息可以看之前我的 《预警：2019年ORACLE SCN 兼容性特性( Compatibility)自动改变的影响》， 这里记录一下11.2.0.1 的修复方法.
