Network Administration - Oracle Exadata Recipes: A Problem-Solution Approach - page 299

the skgxpinfo command returns “ RDS ”. When Oracle ACS installs the software on Exadata, the skgxpinfo.o object file
is compiled with RDS enabled and after this, skgxpinfo is relinked. Once this is complete, Oracle binaries are linked
with ipc_rds . If you check the contents of your /opt/oracle.SupportTools/onecommand/tmp directory, you will see
evidence of this:
[root@cm01dbm01 tmp]# grep ipc_rds *
installActions2011-05-03_03-45-58PM.log: make -f
/u01/app/11.2.0/grid/rdbms/lib/ins_rdbms.mk ipc_rds; \
installActions2011-05-03_04-01-33PM.log: make -f
/u01/app/oracle/product/11.2.0/dbhome_1/rdbms/lib/ins_rdbms.mk ipc_rds; \

10-4. Configuring the SCAN Listener
Problem
You are installing Oracle RAC on Exadata or changing network IP address information and wish to configure your
Oracle SCAN listener.
Solution
In this recipe, you will learn how to list your Oracle SCAN listener configuration and modify your SCAN network and
SCAN listener IP addresses.
Start by checking your current SCAN and SCAN listener configuration:
[grid@cm01dbm01 ~]$ srvctl config scan
SCAN name: cm01-scan, Network: 1/172.16.10.0/255.255.255.0/bondeth0
SCAN VIP name: scan1, IP: /cm01-scan/172.16.10.16
SCAN VIP name: scan2, IP: /cm01-scan/172.16.10.15
SCAN VIP name: scan3, IP: /cm01-scan/172.16.10.1
[grid@cm01dbm01 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521
[grid@cm01dbm01 ~]$
When network resources are configured for an Exadata 11gR2 Grid Infrastructure installation, you are required
to enter a SCAN name; in the previous example, we used a SCAN name of cm01-scan . The nslookup command below
confirms the required three IP addresses for your SCAN network:
Macintosh-8:~ jclarke$ nslookup cm01-scan
Server: 11.11.1.250
Address: 11.11.1.250#53
Name: cm01-scan.centroid.com
Address: 172.16.10.16
Name: cm01-scan.centroid.com
Address: 172.16.10.15
Name: cm01-scan.centroid.com
Address: 172.16.10.14
