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

Oracle版本：10.2.0.2 并做已做data guard
操作系统：linux rhat 5.6 x64

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。
