专家解答
ORA-07445是个BUG,11.2.0.4已经fixed,主要是配置CDC时发生。
Bug 13514083 ORA-7445 [kgscReleaseACursor] may occur when using Change Data Capture
ORA-00600问题是ASSM管理的bug(这个是11.2.0.3之前版本发生,当前版本fixed,但是至少提醒,之前的块头已经有问题了):
Bug 10371288 - ORA-600 [ktspgsb-inc] using ASSM
建议:
1、安装相关的补丁
2、11.2.0.3版本BUG较多,建议升级到11.2.0.4的最新PSU
