1、
节点一(db01)检查情况:
[oraprod@db01 archivelog ]$ lsvg -l sharevg1 | grep lv16_41
lv16_41 raw 128 128 1 closed/syncd N/A --查看格式和使用情况 应该是 raw类型,close状态,下同
[oraprod@db01 archivelog ]$
[oraprod@db01 archivelog ]$ ls -alt /dev/rlv16_41
crw-rw---- 1 oraprod dba 50, 34 Aug 28 13:30 /dev/rlv16_41 --查看权限,应该是数据库用户的,下同
[oraprod@db01 archivelog ]$
2、
$ lsvg -l sharevg1 | grep lv16_41
lv16_41 raw 128 128 1 closed/syncd N/A
$ ls -alt /dev/rlv16_41
crw-rw---- 1 oraprod dba 50, 34 Aug 28 13:31 /dev/rlv16_41
$
验证结果是可以添加该文件。
3、在任意节点打开sqlplus
执行添加命令:
SQL> ALTER TABLESPACE APPS_TS_MEDIA ADD DATAFILE '/dev/rlv16_41' SIZE 16000M AUTOEXTEND OFF;
Tablespace altered.
SQL>
提示成功
4、观看告警日志信息:
Fri Aug 29 09:09:23 2014

最后一行提示添加成功
5、校验结果
5.1节点1登如sqlplus
SQL> show parameter name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert string
db_name string PROD
db_unique_name string PROD
global_names boolean FALSE
instance_name string PROD1
lock_name_space string
log_file_name_convert string
service_names string
SQL> col file_name for a20
SQL> select file_id,file_name from dba_data_files where file_name like '%rlv16_41%';
FILE_ID FILE_NAME
---------- --------------------
252 /dev/rlv16_41
SQL>
5.2节点2登入sqlplus
SQL> show parameter name;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert string
db_name string PROD
db_unique_name string PROD
global_names boolean FALSE
instance_name string PROD2
lock_name_space string
log_file_name_convert string
service_names string PROD
SQL> col file_name for a20
SQL> select file_id,file_name from dba_data_files where file_name like '%rlv16_41%';
FILE_ID FILE_NAME
---------- --------------------
