Oracle数据库克隆实验系列-停机克隆-数据库同名克隆

1、Oracle同名克隆-131服务器上新建库PROD1，然后将其迁移至137服务器，库名仍为PROD1 1.1 dbca-131 PROD1 sys/oracle system/or

1、oracle同名克隆-131服务器上新建库prod1，然后将其迁移至137服务器，，库名仍为prod1
 1.1 dbca-131 prod1
 sys/oracle

 ora-00845 when using dbca to create a database
 starting with oracle database 11g, the automatic memory management feature requires more shared memory (/dev/shm)and file descriptors. the size of the shared memory should be at least the greater of memory_max_target and memory_target for each oracle instance on the computer. if memory_max_target or memory_target is set to a non zero value, and an incorrect size is assigned to the shared memory, it will result in an ora-00845 error at startup.
 

[oracle@oelr5u8-1 admin]$ df -h | grep shm
 tmpfs                2.0G  400M  1.6G  20% /dev/shm
 

for it's only 400M and less than the parameter memory_target=1.6G
 so let's modify it to 2G
 [root@oelr5u8-1 ~]# vi /etc/fstab
 modify:
 tmpfs                  /dev/shm                tmpfs  defaults  0 0
 to:
 tmpfs                  /dev/shm                tmpfs  defaults,size=2G  0 0
 init 6
 

then do the same on 192.168.182.137
