This procedure describes how to modify certain system settings to support the Quick Start configuration.
On both nodes, enable Solaris multipathing functionality.
phys-X# /usr/sbin/stmsboot -e |
Enables Solaris I/O multipathing
For more information, see the stmsboot(1M) man page.
On both nodes, update the /etc/inet/ipnodes file with all public hostnames and logical addresses for the cluster.
Except for the loghost entries, these entries are the same on both nodes.
The IP addresses in this step are for example only and are not valid for use on the public network. Substitute your own IP addresses when you perform this step.
phys-X# vi /etc/inet/ipnodes |
On phys-sun, add the following entries:
127.0.0.1 localhost 192.168.10.1 phys-sun loghost 192.168.10.2 phys-moon 192.168.10.3 apache-lh 192.168.10.4 nfs-lh 192.168.10.5 oracle-lh 192.168.10.6 admincon 192.168.11.1 phys-sun-11 192.168.11.2 phys-moon-11 192.168.11.3 se3510fc-11 192.168.11.4 admincon-11 |
On phys-moon, add the following entries:
127.0.0.1 localhost 192.168.10.1 phys-sun 192.168.10.2 phys-moon loghost 192.168.10.3 apache-lh 192.168.10.4 nfs-lh 192.168.10.5 oracle-lh 192.168.10.6 admincon 192.168.11.1 phys-sun-11 192.168.11.2 phys-moon-11 192.168.11.3 se3510fc-11 192.168.11.4 admincon-11 |
On both nodes, ensure that the following kernel parameters are set to at least the minimum values that Oracle requires.
Display the settings for the default project.
phys-X# prctl -i project default |
If no kernel parameters are set, or if any kernel parameters are not set to the minimum required value for Oracle as shown in the following table, set the parameter.
phys-X# projmod -s -K "parameter=(priv,value,deny)" default |
Oracle Kernel Parameter |
Minimum Required Value |
---|---|
process.max-sem-nsems |
256 |
project.max-sem-ids |
100 |
project.max-shm-ids |
100 |
project.max-shm-memory |
4294967295 |
Verify the new settings.
phys-X# prctl -i project default |
These settings are the minimum required values to support the Oracle software in a Sun Cluster Quick Start configuration. For more information about these parameters, see the Oracle10g Installation Guide.
On both nodes, add the following entries to the /etc/system file.
phys-X# vi /etc/system set ce:ce_taskq_disable=1 exclude:lofs |
The first entry supports ce adapters for the private interconnect.
The second entry disables the loopback file system (LOFS), which must be disabled when Sun Cluster HA for NFS is configured on a highly available local file system. For more information and alternatives to disabling LOFS when Sun Cluster HA for NFS is configured, see the information about loopback file systems in Solaris OS Feature Restrictions in Sun Cluster Software Installation Guide for Solaris OS.
These changes take effect at the next system reboot.
On both nodes, update the /devices and /dev entries.
phys-X# devfsadm -C |
On both nodes, confirm that the storage array is visible.
phys-X# luxadm probe |
