WINDOWS Oracle 18C ORA-00823: Specified value of sga_target greater than sga_max_size

@sga_target greater than sga_max_size

Oracle 18c Windows 误设置sga_max_size后处理

1、SQL>ALTER SYSTEM SET sga_max_size = 500M SCOPE=SPFILE; – 小了

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup nomount
ORA-00823: Specified value of sga_target greater than sga_max_size

2、修改或生成 安装目录WINDOWS.X64_180000_db_home\dbs\init.ora文件
生成的命令
startup pfile=D:\soft\WINDOWS.X64_180000_db_home\dbs\init1.ora

3、电脑上打开修改sga_target sga_max_size 两个参数大小都为1024m，然后启动试下，没毛病，关了库
startup pfile=D:\soft\WINDOWS.X64_180000_db_home\dbs\init1.ora

4、到安装目录 WINDOWS.X64_180000_db_home\database 备份SPFILEORCL.ORA后删了他，生成一个新的SPFILEORCL.ORA命令如下：

CREATE SPFILE=‘D:\soft\WINDOWS.X64_180000_db_home\database\SPFILEORCL.ORA’ FROM PFILE=‘D:\soft\WINDOWS.X64_180000_db_home\dbs\init1.ora’;

5、启动 startup
