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

Oracle版本：10.2.0.2 並做已做data guard
作業系統：linux rhat 5.6 x64

最近在主庫oracle alert日誌發現，最近半個月，幾乎每天都會產生一次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日誌有
Errors in file/oracle/admin/hycrm/bdump/hycrm_mrp0_8323.trc:
ORA-16099: internal error ORA-00600 occurred at standbydatabase

查看主備的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)
    )
  )

發現主庫串連串中缺少(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串連有關係。
