双机数据源配置格式：

jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=yes)(FAILOVER=no)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.176.216.92)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=10.176.216.91)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=mdscsdb)))

单机数据源配置格式：jdbc:oracle:thin:@10.176.216.91:1521:mdscsdb1

修改BPM数据源涉及的配置文件:一：

/home/Oracle/user_projects/domains/bpm_domain/applications/default.war/WEB-INF/_srv/config/MultisysRemoteBSPDataSource.properties


二：网页控制台新增数据源

weblogic 报错:LOOKUP BPS service failed!(记得先备份)
解决方案:将${WEBLOGIC_HOME}/modules/目录下的commonj.sdo_1.0.0.0_1-0.jar删除;
并将org.eclipse.persistence_1.1.0.0_2-1.jar中的commonj包删除 在重启

Linux运维清空正在运行的应用日志文件内容:
第一种方法:

file.log
第二种方法:
echo “” > file.log
第三种方法:
cat /dev/null > file.log

通过PID查询java进程

ps -ef -o stat,pid,cmd |grep java | awk ‘{print $2}’ | xargs pwdx
 ps -ef |grep java |awk ‘{print $2}’ |xargs pwdx

修改数据库端口（RAC及单机）

Oralce11g RAC集群数据库修改监听端口号(grid用户)

srvctl modify listener -l LISTENER -p “TCP:11521”
 srvctl modify scan_listener -p 11521

查询备份

show parameter local_listener;
 local_listener string (ADDRESS=(PROTOCOL=TCP)(HOST=10.176.216.96)(PORT=1521)) --私网IP
 show parameter remote_listener;(到数据库中去验证remote_listener的端口参数是否被修改成功,如果没有则在PL/SQL中进行修改,即使用oracle用户进行验证)
 remote_listener string scan-cluster:1521

修改参数

sqlplus / as sysdba
 alter system set local_listener=‘(ADDRESS=(PROTOCOL=TCP)(HOST=10.176.216.96)(PORT=11521))’ scope=both sid=‘mdscsdb1’;
 alter system set local_listener=‘(ADDRESS=(PROTOCOL=TCP)(HOST=10.176.216.97)(PORT=11521))’ scope=both sid=‘mdscsdb2’;
 alter system set remote_listener=‘scan-cluster:11521’ scope=both;

在第一个节点重启本地监听

srvctl stop listener -l LISTENER -n mdscsdb1


修改第一个节点的$ORACLE_HOME/network/admin/endpoints_listener.ora文件,将1521改为11521

srvctl start listener -l LISTENER -n mdscsdb1

在第二个节点重启本地监听

srvctl stop listener -l LISTENER -n mdscsdb2


修改第二个节点的$ORACLE_HOME/network/admin/endpoints_listener.ora文件,将1521改为11521

srvctl start listener -l LISTENER -n mdscsdb2

重启集群监听

srvctl stop scan_listener
 srvctl start scan_listener

重启数据库

Oralce11g 单机数据库修改监听端口号(grid用户)

1.查看监听状态:
$lsnrctl status;

2.停止监听:
$lsnrctl stop;

3.修改配置文件:
$vi $ORACLE_HOME/network/admin/listener.ora
将1521端口进行更换

4.登录并查看local_listener参数
$sqlplus / as sysdba

show parameter local_listener;
(此时的VALUE值应为空)

5.修改local_listener参数

alter system set local_listener=“(address = (protocol=tcp)(host=10.176.216.194)(port=9999))” #host后面加主机名或者IP

6.查看local_listener参数

show parameter local_listener

7.启动监听
$lsnrctl start

8.查看状态
$netstat -antup | grep 9999
$lsnrctl status

如果启用了防火墙,记得开放端口
$su - root

/sbin/iptables -l INPUT -p tcp --DPORT 9999 -j ACCEPT

/etc/rc.d/init.d/iptables save

到此oracle的监听端口就已经由原来的1521变成9999

Oralce10g RAC集群数据库修改监听端口号(oracle用户)

1、$cd $ORACLE_HOME/network/admin

2、修配配置文件listener.ora

3、查看local_listener:
SQL>show parameter local;
SQL>show parameter remote_listener;

4、修改配置文件tnsnames.ora

5、两个节点上启动新的端口:
linux postgre 修改数据库名 linux修改数据库端口_TCP lsnrctl status命令查询)

 The command completed successfully

6、在另一个节点可以用set current_listener LISTENER_O10N2命令启动

LSNRCTL>start
$lsnrctl status 当前正在监听的节点的名称(LISTENER_CMSPDB1)

注意,此时新端口已经启动好了,并且可以连接了,但是原端口还是可以连接的,可通过lsnrctl status命令查询

如果需要关掉原来的端口,可以通过lsnrctl stop关掉,但是不能用srvctl关掉。这样会关掉新端口的监听,不会关掉原端口的监听

$srvctl stop listener -l LISTENER -n CMSPDB1
