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

uncheck all components

no Flashback
no Archiving
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
