監(jiān)控或統(tǒng)計多套數(shù)據(jù)庫的存儲容量與備份

發(fā)布時間：2020-08-13 18:35:19 來源：ITPUB博客閱讀：142 作者：skyin_1603 欄目：關系型數(shù)據(jù)庫

  為了減少監(jiān)控或同級多套數(shù)據(jù)庫存儲容量或者備份檢查的工作量，可以考慮使用一個專門做監(jiān)控服務器，
通過配置一些需要到的配置表，然后以sh腳本或者存儲過程形式固化采集多套庫的存儲容量情況或者備份情況的
方式，形成簡易的采集流程，大大簡化了重復而繁瑣的數(shù)據(jù)庫管理工作。

配置方法：
1、監(jiān)控服務器；
2、監(jiān)控服務器通往各個被監(jiān)控服務器dblink的配置表，（如下 suxing.conf11g_dblink_tab或者suxing.CONF_BACKUPCHECK_DBLINK_TAB）
----由于兩個配置表的功能有所差異，所以分開兩個配置表；
3、專門作監(jiān)控的用戶；
4、腳本或者存儲過程（如下多個服務器容量統(tǒng)計腳本和多個服務器備份檢查結果采集腳本）；
5、存放采集數(shù)據(jù)的表（如下 suxing.space_gather11G_tab或者 suxing.db_backup_check_alltab）。

#####多個服務器容量統(tǒng)計腳本：
declare
v_sql varchar2(4000);
begin
for rec in (select * from suxing.conf11g_dblink_tab) loop
v_sql :='insert into suxing.space_gather11G_tab
select * from (
with
I as (select instance_name from v$instance@'||rec.db_link||'),
A as (select round(sum(bytes)/1024/1024/1024,2) aa from dba_data_files@'||rec.db_link||'),
B as (select round(sum(bytes)/1024/1024/1024,2) bb from dba_free_space@'||rec.db_link||'),
C as (select round(sum(BYTES / 1024 / 1024 / 1024), 2) cc
from v$datafile@'||rec.db_link||' a, v$tablespace@'||rec.db_link||' b
where a.TS# = b.TS#
and a.CREATION_TIME <
to_date(''2017-07-15 10:00:00'', ''YYYY-MM-DD HH24:MI:SS'')),
D as (select round(sum(BYTES / 1024 / 1024 / 1024), 2) dd
from v$datafile@'||rec.db_link||' a, v$tablespace@'||rec.db_link||' b
where a.TS# = b.TS#
and a.CREATION_TIME <
to_date(''2017-04-15 00:00:00'', ''YYYY-MM-DD HH24:MI:SS'')),
E as (select round(sum(BYTES / 1024 / 1024 / 1024), 2) ee
from v\$datafile@'||rec.db_link||' a, v\$tablespace@'||rec.db_link||' b
where a.TS# = b.TS#
and a.CREATION_TIME <
to_date(''2017-06-15 00:00:00'', ''YYYY-MM-DD HH24:MI:SS'')),
G as (select GROUP_NUMBER,NAME,TOTAL_MB/1024 totalGB,FREE_MB/1024 freeGB
from v$asm_diskgroup@'||rec.db_link||' where name like ''DATA%'')
select I.instance_name,A.aa Total_G,A.aa-B.bb Used_G,B.bb Free_G,G.totalGB,G.freeGB,(C.cc - D.dd)/3 AVRG3,C.cc - E.ee,sysdate,to_char(sysdate,''yymmdd'')
from I,A,B,C,D,E,G
)';
--dbms_output.put_line(v_sql);
execute immediate v_sql;
commit;
end loop;
end;

#####多個服務器備份檢查結果采集腳本：
declare
v_sql varchar2(4000);
begin
for rec in (select * from suxing.CONF_BACKUPCHECK_DBLINK_TAB) loop
v_sql :='insert into suxing.db_backup_check_alltab
select * from (
with
I as (select instance_name from v$instance@'||rec.db_link||'),
BC as (
select start_time, t.INPUT_TYPE, status
from v$rman_backup_job_details@'||rec.db_link||' t
where t.start_time in (select max(start_time)
from v$rman_backup_job_details@'||rec.db_link||')
and t.INPUT_TYPE = ''ARCHIVELOG''
group by t.start_time, t.INPUT_TYPE, t.STATUS
union all
select start_time, t.INPUT_TYPE, status
from v$rman_backup_job_details@'||rec.db_link||' t
where t.start_time in (select max(start_time)
from v$rman_backup_job_details@'||rec.db_link||' t
where t.INPUT_TYPE = ''DB INCR'')
group by t.start_time, t.INPUT_TYPE, t.STATUS)
select I.instance_name,BC.*,to_char(sysdate,''mmddhh34'') from I,BC)';
--dbms_output.put_line(v_sql);
execute immediate v_sql;
commit;
end loop;
end;

注：這些腳本當中，with子句的作用非常關鍵。
