1.配置测试环境
创建数据表空间
create tablespace test logging datafile '/home/oracle/test.dbf' size 10m autoextend on next 10m maxsize 2048m extent management local;
创建用户并指定表空间
create user test identified by 123456 default tablespace test;
给用户授予权限
grant connect,resource,dba to test;
创建表
sqlplus test/123456@orcl
[root@12c-1 ~]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 15653 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) unlimited cpu time (seconds, -t) unlimited max user processes (-u) 15653 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited 安装12c的时候提示maximun stack size 过小 ulimit -a ulimit -s unlimited 重新安装12c 可以通过
2.文件系统表空间迁移到ASM中去
rman target /
report schema; 查看表空间
sql 'alter tablespace test offline';离线表空间
backup as copy datafile 5 format '+DATA';Copy类型备份表空间
switch datafile 5 to copy;切换表空间文件到copy副本
sql 'alter tablespace test online';上线表空间
report schema;
sqlplus test/123456@orcl
2 select tname from tab;
