簡(jiǎn)單查看oracle的連接情況和內(nèi)存使用情況

1、查看連接oracle的所有機(jī)器的連接數(shù)

select machine,count(*) from v$session group by machine;

2、查看連接oracle的所有機(jī)器的連接數(shù)和狀態(tài)

select machine,status,count(*) from v$session group by machine,status order by status;

3、oracle的PGA、SGA和process count

select 'SGA' AS NAME,ROUND(sum(value)/1024/1024,2)||'M' AS "SIZE(M)" from v$sga UNION select 'PGA' AS NAME,ROUND(value/1024/1024,2)||'M' AS "SIZE(M)" from v$pgastat where name='total PGA allocated' UNION select 'TOTAL' AS NAME,((SELECT ROUND(sum(value)/1024/1024,2) from v$sga)+(select ROUND(value/1024/1024,2) from v$pgastat where name='total PGA allocated'))||'M' AS "SIZE(M)" FROM DUAL UNION SELECT NAME,TO_CHAR(VALUE) FROM V$PGASTAT WHERE NAME='process count';

5、Oracle 11g設(shè)置內(nèi)存自動(dòng)管理:

ALTER SYSTEM SET MEMORY_TARGET = 1024M SCOPE=SPFILE; ALTER SYSTEM SET memory_max_target = 1500M SCOPE=SPFILE; ALTER SYSTEM SET SGA_TARGET = 0 SCOPE=SPFILE; ALTER SYSTEM SET SGA_MAX_SIZE=800M SCOPE=SPFILE; ALTER SYSTEM SET PGA_AGGREGATE_TARGET = 0 SCOPE=SPFILE; alter system set pre_page_sga=FALSE scope=spfile;

創(chuàng)作挑戰(zhàn)賽新人創(chuàng)作獎(jiǎng)勵(lì)來(lái)咯，堅(jiān)持創(chuàng)作打卡瓜分現(xiàn)金大獎(jiǎng)

總結(jié)

以上是生活随笔為你收集整理的oracle连接的内存,简单查看oracle的连接情况和内存使用情况 -电脑资料的全部?jī)?nèi)容，希望文章能夠幫你解決所遇到的問(wèn)題。
