oracle參數MEMORY_TARGET太小無法啟動的解決過程

環境：

windows server 2008 datacenter 4G，4x2=8處理器
oracle 11g

 

 

錯誤如下

ORA-00838: Specified value of MEMORY_TARGET is too small, needs to be at least 936M

 

創建文件

create pfile='$ORACLE_HOME/dbs/spfileorcl_bak.ora' from spfile;

 

 

該文件的內容如下：

修改為1073741824
即1G

修改后保存

startup pfile='C:/app/Administrator/product/11.2.0/dbhome_1/dbs/spfileorcl_bak.ora';

 

卡了挺長時間的；
一直在啟動中，后面關掉重新startup，提示已經有個啟動進程中，文件無法加鎖，就重啟了服務器；
重啟服務器后再測試，可以啟動了：

再利用pfile創建 spfile

create spfile from pfile='C:/app/Administrator/product/11.2.0/dbhome_1/dbs/spfileorcl_bak.ora';

 

可直接重啟
