  • oracle 11g 修改内存示例

    增加Oracle内存示例:

    环境:集群环境Oracle 11.2.0.0.4 

    脚本示例如下

    操作系统修改shm 为3072M ,sqlplus中备份spfile生成pfile,修改pfile中mem参数,使用pfile启动,创建spfile,完毕。

    [root@rac2 ~]# df -h | grep shm
    tmpfs                    1.9G  459M  1.5G  25% /dev/shm
    [root@rac2 ~]# grep /etc/fstab
    ^C
    [root@rac2 ~]# grep shm /etc/fstab
    [root@rac2 ~]# vi /etc/fstab 
    [root@rac2 ~]# grep shm /etc/fstab
    tmpfs /dev/shm                    tmpfs    defaults,size=3072m        0 0
    [root@rac2 ~]# mount -o remount tmpfs
    [root@rac2 ~]# df -h | grep shm
    tmpfs                    3.0G  459M  2.6G  15% /dev/shm
    [root@rac2 ~]# 
    

      fstab文件如下

    [root@rac2 ~]# cat /etc/fstab 
    
    #
    # /etc/fstab
    # Created by anaconda on Tue Sep 14 23:19:16 2021
    #
    # Accessible filesystems, by reference, are maintained under '/dev/disk'
    # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
    #
    /dev/mapper/centos-root /                       xfs     defaults        0 0
    UUID=e123d649-cfa2-45f6-b49c-eb994a56c914 /boot                   xfs     defaults        0 0
    /dev/mapper/centos-swap swap                    swap    defaults        0 0
    tmpfs /dev/shm                    tmpfs    defaults,size=3072m        0 0
    [root@rac2 ~]# 
    

      

    sqlplus 中操作如下:

    [oracle@rac2 ~]$ sqlplus / as sysdba
