  • ORA-01102 报错解决方法

    Problem Explanation: 
    ====================  
    A database is started in EXCLUSIVE mode by default.  Therefore, the  
    ORA-01102 error is misleading and may have occurred due to one of the  
    following reasons: 
      - there is still an "sgadef<sid>.dbf" file in the "ORACLE_HOME/dbs" 
        directory  
      - the processes for Oracle (pmon, smon, lgwr and dbwr) still exist 
      - shared memory segments and semaphores still exist even though the  
        database has been shutdown 
      - there is a "ORACLE_HOME/dbs/lk<db_name>" file 
    Solution Description: 
    ===================== 
    Verify that the database was shutdown cleanly by doing the following: 
    1. Verify that there is not a "sgadef<sid>.dbf" file in the directory 
       "ORACLE_HOME/dbs".   
       % ls $ORACLE_HOME/dbs/sgadef<sid>.dbf 
       If this file does exist, remove it. 
       % rm $ORACLE_HOME/dbs/sgadef<sid>.dbf 
    2. Verify that there are no background processes owned by "oracle"  
       % ps -ef | grep ora_ | grep $ORACLE_SID 
       If background processes exist, remove them by using the Unix  
       command "kill".  For example: 
       % kill -9 <Process_ID_Number> 
    3. Verify that no shared memory segments and semaphores that are owned  
       by "oracle" still exist 
       % ipcs -a 
       If there are shared memory segments and semaphores owned by "oracle",
       remove the shared memory segments  
       % ipcrm -m <Shared_Memory_ID_Number> 
       and remove the semaphores  
       % ipcrm -s <Semaphore_ID_Number> 
    NOTE:  The example shown above assumes that you only have one  
           database on this machine.  If you have more than one 
           database, you will need to shutdown all other databases 
           before proceeding with Step 4. 
    4. Verify that the "$ORACLE_HOME/dbs/lk<db_name>" file does not exist 
       if exit,remove it use ‘rm’ command.
    5. Startup the instance
