NetBackup SAN Client光纤连接

通常SAN Switch连接设计为：

  • FT Media Server启用Target 模式的端口连接到SAN Switch（假设1口）
  • Client端口连接到SAN Switch（假设2口）
  • 1口和2口创建一个Zone。

    • 在配置完成后，在JavaConsole中看不到设备，FT Media Server日志中可以看到：

    NetBackup FT Media Server配置

    FT Media Server 配置

    在Media Server上启动NBHBA模式：

    /usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhba
 
Example:
 
/usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhba
Installing nbhba driver. Are you sure you want to unload QLogic driver: qla2300? [y,n] (y)
/usr/sbin/update_drv-v-d-i "pci1077,2312.1077.12a" qlc
Done copying driver into system directories. Done adding driver.
MUST REBOOT TO COMPLETE INSTALLATION.

    重启主机，完成后可通过以下命令查看HBA口信息

    NetBackup SAN Client Overview

    SAN Client是NetBackup的一个特殊客户端，它的作用是让主机在不部署Media Server的情况下，也能通过SAN进行备份，它有以下特点：

    • 拥有传输大量数据的能力。
    • 替代Media Server，主机不部署为Media Server也能使用SAN传输数据。

    SAN Client涉及的技术：

    • Fibre Transport(FT) ，一种数据传输方式，通过在SAN或者LAN上传输SCSI指令。
    • FT Media Server, 指启用了FT功能的Media Server。
    • FT Service Manager(FSM), 像EMM一样运行的进程，FSM负责Clients和FT Media Server的交互，负责发现、配置、监视及分配FT资源。
    • Target Mode Driver, 替换系统驱动，只适用于Qlogic HBA卡。

    命令创建ACFS

    创建挂载点

    mkdir -p /u01/app/oracle/acfsmounts/data_acfsvol3
chown oracle:oinstall /u01/app/oracle/acfsmounts/data_acfsvol3

    连接到ASM创建Volume

    su - oracle
[oracle@rac1 ~]$ . oraenv
ORACLE_SID = [RAC1] ? +ASM1
The Oracle base for ORACLE_HOME=/u01/app/11.2.0/grid is /u01/app/oracle
[oracle@rac1 ~]$ dbhome
/u01/app/11.2.0/grid
[oracle@rac1 ~]$ sqlplus / as sysasm
Issue to the following command to create a new volume.
 
SQL> ALTER DISKGROUP DATA ADD VOLUME ACFSVOL3 SIZE 10G;
 
Diskgroup altered.

    在11gR2中使用RMAN复制数据库

    RMAN 可以通过复制或者克隆，从一个运行的库中复制一个备份。可以用来在远程站点上复制数据库，下面示例中源库和复制库使用同样的SID：DB11G

    在源库中创建备份。

    $ rman target=/
 
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN> BACKUP DATABASE PLUS ARCHIVELOG

    为目标库创建password文件

    $ orapwd file=/u01/app/oracle/product/11.2.0/db_1/dbs/orapwDB11G password=password entries=10

    在”$ORACLE_HOME/network/admin” 中增加”tnsnames.ora” 允许目标库访问源库。

    # Added to the tnsnames.ora
DB11G-SOURCE =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ol5-112-dup1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (ORACLE_SID = DB11G)
    )
  )
