ORA-00600: internal error code, arguments: [opifal.1]

oracle版本：10.2.0.2 并做已做data guard 作業系統：linux rhat 5.6 x64

最近在主庫oracle alert日志發現，最近半個月，幾乎每天都會産生一次ora 600錯誤，如下： Errors in file/oracle/admin/hycrm/bdump/hycrm_s000_27823.trc:

ORA-00600: internal error code, arguments: [opifal.1], [], [], [],[], [], [], []

備庫的alert日志有 Errors in file/oracle/admin/hycrm/bdump/hycrm_mrp0_8323.trc: ORA-16099: internal error ORA-00600 occurred at standbydatabase

檢視主備的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)     )   )

發現主庫連接配接串中缺少 (SERVER =DEDICATED)，添加後，跟蹤觀察，ora 600錯誤消失。 此錯誤應該和專有模式連接配接有關系。
