RAC Attack - Oracle Cluster Database at Home/Install Instant Client

In order to test failover it would be best to connect from a client outside the cluster, so we'll start by downloading and installing Oracle's Basic Instant Client (English-only) and the Instant Client SQLPlus package.

 Login to the node collabn1 as user oracle and open a connection to the database as SYSDBA and unlock the SH user account. Also grant DBA access. SQL> alter user sh identified by sh account unlock; User altered. SQL> grant dba to sh; Grant succeeded.

 Download Oracle's Basic (English-only) Instant Client and Oracle's Instant Client SQLPlus package. The lab instructor may have made them available, or they can also be downloaded from Oracle's website here:

http://www.oracle.com/technetwork/topics/winsoft-085727.html

The two files you need are:
 * instantclient-basiclite-*.zip
 * instantclient-sqlplus-*.zip

 Each archive contains a folder named "instantclient_11_2". Extract this folder (from both archives) into C:\. (In Explorer you can drag-and-drop or you can choose "Extract All" from the File menu.)

 Edit c:\windows\system32\drivers\etc\hosts and add IP addresses for the RAC nodes.

192.168.78.250	collab-scan.vm.ardentperf.com collab-scan 192.168.78.61	collabn1-vip.vm.ardentperf.com collabn1-vip 192.168.78.62	collabn2-vip.vm.ardentperf.com collabn2-vip 192.168.78.51	collabn1.vm.ardentperf.com collabn1 192.168.78.52	collabn2.vm.ardentperf.com collabn2



 Test your Instant Client installation by connecting to the database.

C:\instantclient_11_2> sqlplus sh/sh@//collab-scan/RAC.vm.ardentperf.com



 Create a TNSNAMES files and copy the RAC, RAC1 and RAC2 entries from either cluster database node.

C:\instantclient_11_2> notepad C:\instantclient_11_2\tnsnames.ora RAC = (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = collab-scan)(PORT = 1521))     (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = RAC.vm.ardentperf.com) )  ) RAC2 = (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = collabn-scan)(PORT = 1521))     (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = RAC.vm.ardentperf.com) (INSTANCE_NAME = RAC2) )  ) RAC1 = (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = collabn-scan)(PORT = 1521))     (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = RAC.vm.ardentperf.com) (INSTANCE_NAME = RAC1) )  )

 Test your TNSNAMES by setting the TNS_ADMIN environment variable and running SQLPLUS.

C:\instantclient_11_2>set TNS_ADMIN=c:\instantclient_11_2 C:\instantclient_11_2>sqlplus sh/sh@RAC
