启动主备另外节点

--主库
[oracle@q9db01 ~]$ srvctl start instance -d q9db -i q9db2
--备库
[oracle@q9adg02 ~]$ srvctl start instance -d q9db_adg -i q9db2

补充说明:如果出现日志切换暂时不能传输

备库执行(因为重启动态监听没有马上别识别)
alter system register;
主库执行
alter system set log_archive_dest_state_2=enable;

在11GR2 GI上配置第二个监听

发表于 2013 年 6 月 19 日 由 惜分飞

有客户因为归档日志量每天很大,为了不影响业务,需要配置一个单独的万兆网络来专门的传输归档日志到DG库,这里就涉及到在11G(11203 Linux) RAC中增加一个监听用来使用专门的网络.这里提供在主库配置第二个监听的整体操作过程,主要涉及配置解析,增加网络,增加vip,配置监听,配置listener_networks

ORACLE 12C RMAN 功能增强

发表于 2013 年 6 月 17 日 由 惜分飞

在ORACLE 12C中对rman的功能有了不少增强,在以前的文章中写过RMAN RECOVER TABLE功能,这里另外补充rman增强的两个小功能(sql语句和数据文件分割)
数据库版本

SQL>  select * from v$version;

这里看到rman只是sql语句中的select和desc用法

rman分割数据文件增强

在12C之前的版本，ORACLE 11GR2只是对于全备的备份集备份(非增量,非copy备份方式)方式支持数据文件分割备份功能,对于11.2之前的版本均不支持该功能.在12C中rman可以支持对于全备,增量备份,copy备份全部支持分割数据文件备份(CONTROLFILE,SPFILE不支持)
