Oracle 创建监控账户 提高工作效率

有很多Oracle服务器,需要天天查看TableSpace,比较麻烦了。

为了把事情变成简单化,我在多个Oracle数据上建立统一的检查数据库账户,并且账户只能访问特定的几个视图(需要查询的sql已生成视图),具体做法如下:

root>sqlplus / as sysdba
用DBA的权限进入数据库,需要创建一个账户
http://www.jb51.net/article/20367.htm

SQL>create user dbmonitor identified by "ty_sd_s";
给账户授权
SQL>grant connect,resource to dbmonitor;

此账户执行的脚本转换成视图
代码如下:
SQL> drop view vstablespace;
SQL> create view vstablespace as
(
select
a.tablespace_name "TABLESPACE",
sum(a.bytes) SUM ,
sum(b.bytes) FREE ,
sum(b.bytes)/sum(a.bytes)*100 PRECENTFREE
from
dba_data_files
a,dba_free_space b
where
a.file_id=b.file_id
group by a.tablespace_name
)


给用户赋予select试图的权限
SQL>grant select on vstablespace to dbmonitor ;

如此下来,这个用户只能查看此数图,不能改动其他的,就可以保证数据库的安全了

退出,再用新建的oracle账户登录
root>sqlplus dbmonitor/"ty_sd_s" as sysdba;
进入之后查看用户所赋予的权限
SQL>select * from user_tab_privs;

从这里看到只用新建视图的权限
SQL>select * from sys.vstablespace ;

The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

How much memory does oracle require? How much memory does oracle require? May 10, 2024 am 04:12 AM

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.
