How to Enable liveCache to Run in a Cluster
During a standard SAP installation, liveCache is installed with a physical hostname.
You must modify liveCache to use a logical hostname so that liveCache works in a
Oracle Solaris Cluster environment. Use this procedure to enable liveCache to run in a
cluster.
Before You Begin
Ensure that the /etc/netmasks file has IP-address subnet and netmask
entries for all logical hostnames. If necessary, edit the /etc/netmasks file to
add any missing entries.
-
Create the failover resource group to hold the network and liveCache
resource.
# clresourcegroup create [-n node-list] livecache-resource-group
-
Verify that you added all the network resources you use to your name service database.
-
Add a network resource (logical hostname) to the failover resource group.
# clreslogicalhostname create -g livecache-resource-group \
-h lc-logical-hostname lc-logical-hostname
Note -
If you require a fully qualified hostname, you must specify the fully qualified name with the
-h option and you cannot use the fully qualified form in the resource
name.
-
Enable the failover resource group.
# clresourcegroup online -M livecache-resource-group
-
Enable the network resource (logical hostname).
# clresource enable lc-logical-hostname
-
Log on to the node that hosts the liveCache resource group.
-
As the liveCache administrator user, start SAP xserver manually on the node that
hosts the liveCache resource group.
# su - lc-name adm
$ x_server start
- lc-name
-
Lowercase name of liveCache database instance
-
Log on to SAP APO System by using your SAP GUI with user DDIC.
-
Go to transaction LC10 and change the liveCache host to the logical hostname you
defined in Step 3.
liveCache host: lc-logical-hostname
