参考原始：
GoldenGate Processes Abend with OGG-00868 ORA-02396: Exceeded Maximum Idle Time, Please Connect Again (Doc ID 1393647.1)

适用于：
Oracle GoldenGate - Version: 11.1.1.0.0 to 11.1.1.1.20 - Release: 11.1.1 to 11.1.1.1
Information in this document applies to any platform.

症状：
Oracle GoldenGate (OGG) 进程abend，其报错为：

Extract (or replicat)进程
ERROR OGG-00868 ORA-02396: exceeded maximum idle time, please connect again.

Manager 进程
ERROR OGG-00665 OCI Error describe for query (bad syntax) (status = 2396-ORA-02396: exceeded maximum idle time, please connect again), SQL<SELECT 1 FROM DUAL WHERE EXISTS ( SELECT 'x' FROM GGS_OWNER.GGS_MARKER WHERE OPTIME < '...')>.
ERROR OGG-01668 PROCESS ABENDING.

原因：
用户连接超时会发生该问题。检查该用户是否设置了time out。

解决方式：
SQL> select USERNAME,USER_ID,ACCOUNT_STATUS,PROFILE from dba_users where USERNAME='ggs_owner';
确认profile是用的哪个，然后再检查 gg user的 idle timeout情况：

SQL> select * from dba_profiles where resource_name='IDLE_TIME';

如果查询结果以gg user使用profile，检查profile是否有任何限制，或者设置为UNLIMITED

如果 UNLIMITED 不可行，这一增长time out的时间到一个合适的值。
