今天在項目開發中，發現數據庫連接數過多，oracle中存在很多超時連接。導致新增客戶端無法連接到數據庫。所以設置了強制釋放oracle連接屬性。
在網上查詢了設置說明如下：
sqlplus /nolog
打開sqlplus
connect system/bianqiwei@orcltns as sysdba
使用具有dba權限得用戶登陸oracle
show parameter resource_limit
顯示資源限定是否開啓,value爲true是開啓,爲false是關閉
alter system set resource_limit=true
如果未開啓,則使用此命令開啓資源限定功能
create profile profileName limit connect_time 60 idle_time 30
創建profile文件,profileName任意起,connect_time設置連接超過多少分鐘後強制釋放,idle_time設置連續不活動的會話超過多少分鐘後強制釋放
alter user oracleUser profile profileName
將profile文件作用於指定用戶
在數據庫中的實際操作如下：
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
[oracle@nsn-db-server ~]$ sqlplus "/ as sysdba"
