最近在主库oracle alert日志发现，最近半个月，几乎每天都会产生一次ora 600错误，如下：
Errors in file/oracle/admin/hycrm/bdump/hycrm_s000_27823.trc:
ORA-00600: internal error code, arguments: [opifal.1], [], [], [],[], [], [], []
备库的alert日志有
Errors in file/oracle/admin/hycrm/bdump/hycrm_mrp0_8323.trc:
ORA-16099: internal error ORA-00600 occurred at standbydatabase
查看主备的tnsnames.ora的dg配置如下：
hycrm =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.110.23)(PORT =1521))
)
(CONNECT_DATA =
(SERVICE_NAME =hycrm)
)
)
hycrm_std =
(DESCRIPTION =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.110.24)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID= hycrm)
)
)
发现主库连接串中缺少(SERVER =DEDICATED)，添加后，跟踪观察，ora 600错误消失。
此错误应该和专有模式连接有关系。
