Use this procedure to prepare for the installation and configuration of Siebel.
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.
On each node that can master the logical host that runs HA for Siebel, include the following entries in the /etc/nsswitch.conf file.
passwd: files dns publickey: files dns project: files dns group: files dns
HA for Siebel uses the su - user command to start, stop, and probe the service.
The network information name service might become unavailable when a cluster node's public network fails. Adding the preceding entries ensures that the su command does not refer to the NIS/NIS+ name services if the network information name service is unavailable. For more information, see the su(1M) man page. For more information on the svccfg command, see the svccfg(1M) man page.
When the node running the Siebel Gateway has a path beginning with /home (which depends on network resources such as NFS and NIS) and the public network fails, the Siebel Gateway probe times out and causes the Siebel Gateway resource to go offline. Without the public network, Siebel Gateway probe hangs while trying to open a file on /home, causing the probe to time out.
To prevent the Siebel Gateway probe from timing out while trying to open a file on /home, configure all nodes of the cluster that can be the Siebel Gateway as follows:
You might have a locally mounted /home path or you can rename the /home mount point to /export/home or another name which does not start with /home.
Ensure that group IDs are the same on all of the nodes that run HA for Siebel.
siebel:*:521:siebel
You can create group entries in a network name service. If you do so, also add your entries to the local /etc/inet/hosts file to eliminate dependency on the network name service.
The following command updates the /etc/passwd and /etc/shadow files with an entry for the Siebel administrator.
# useradd -u 121 -g siebel -s /bin/ksh -d /Siebel-home siebel
Ensure that the Siebel user entry is the same on all of the nodes that run HA for Siebel.
export ORACLE_HOME=/global/oracle/OraHome export PATH=$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib export TNS_ADMIN=$ORACLE_HOME/network/admin export ORACLE_SID=siebeldb
# clresourcegroup create [-n node] failover-rg
Specifies the node name that can master this resource group.
Specifies your choice of the name of the failover resource group to add. This name must begin with an ASCII character.
Ensure that logical hostname matches the value of the SIEBEL_GATEWAY environment variable that is set in the siebenv.sh file of the Siebel Gateway, and also the Siebel Server installations.
# clreslogicalhostname create -g failover-rg logical_host
Specifies an optional resource name of your choice.
# clresourcegroup online -M failover-rg
