How to Register and Configure HA for Oracle iPlanet Web Server in a Failover Configuration

This procedure describes how to use the Oracle Solaris Cluster maintenance commands to register and configure HA for Oracle iPlanet Web Server in a failover configuration.


Note -  Other options also enable you to register and configure the data service. See Tools for Data Service Resource Administration in Oracle Solaris Cluster Data Services Planning and Administration Guide for details about these options.

To perform this procedure, you must have the following information.

  • The name of the resource type for HA for Oracle iPlanet Web Server. This name is SUNW.iws.

  • The names of the cluster nodes that master the data service. For a failover service, only one node can master a data service at a time.

  • The logical hostname (for failover services) or shared address (for scalable services) that clients use to access the data service.

  • The path to the Oracle iPlanet binaries. You can install the binaries on the local disks or the cluster file system. See Configuration Guidelines for Oracle Solaris Cluster Data Services in Oracle Solaris Cluster Data Services Planning and Administration Guide for a discussion of the advantages and disadvantages of each location.


    Note -  The Resource_dependencies setting on the Oracle iPlanet application resource determines the set of IP addresses that Oracle iPlanet Web Server uses. The Port_list setting on the resource determines the list of port numbers that Oracle iPlanet Web Server uses. The fault monitor assumes that the Oracle iPlanet Web Server daemon is listening on all combinations of IP and port. You can configure the server.xml file for the Oracle iPlanet Web Server to listen on different port numbers (in addition to port 80). The fault monitor attempts to probe all such combinations and starts to fail if the Oracle iPlanet Web Server is not listening on a particular IP address-port combination. If the Oracle iPlanet Web Server does not serve all IP address-port combinations, you must break the Oracle iPlanet Web Server into separate instances that do.
  • 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.


Note -  Perform this procedure on any cluster member.
  1. On a cluster member, become an administrator that provides solaris.cluster.modify and solaris.cluster.admin authorization.
  2. Register the SUNW.iws resource type for HA for Oracle iPlanet Web Server.
    # clresourcetype register SUNW.iws
  3. Create a failover resource group.

    You can optionally select the set of nodes on which the data service can run with the –n option.

    # clresourcegroup create [-n node[,…]] resource-group
    resource-group

    Specifies the name of the failover resource group. This name can be your choice but must be unique for resource groups within the cluster.

    –n node[,…]

    Specifies a comma-separated, ordered list of nodes that can master this resource group.

    This list is optional. If you omit this list, the global zone of each cluster node can master the resource group.

  4. Verify that all of the network addresses that you use have been added to your name service database.

    You should have performed this verification during the Oracle Solaris Cluster installation. See the planning chapter in the Oracle Solaris Cluster Software Installation Guide for details.


    Note -  To avoid any failures because of name service lookup, ensure that all logical hostnames and shared addresses are present in the server's and client's /etc/inet/hosts file. Configure name service mapping in /etc/nsswitch.conf on the servers to first check the local files before trying to access NIS or NIS+.
  5. Add a logical hostname to the failover resource group.
    # clreslogicalhostname create -g resource-group \
    -h logical-hostname[,…] \
    [-p auxnodelist=node] [-N netiflist] resource-name
    –g resource-group

    Specifies the name of the failover resource group.

    –h logical-hostname[,…]

    Specifies a comma-separated list of logical hostnames that this resource is to make available.

    –p auxnodelist=node,…

    Specifies an optional comma-separated list of physical node IDs that identify cluster nodes that can host the shared address but never serve as a primary if failover occurs. These nodes are mutually exclusive with the nodes identified in nodelist for the resource group, if specified.

    resource-group

    Specifies the name of the resource group. This name can be your choice but must be unique for resource groups within the cluster.

    –N netiflist

    Specifies an optional, comma-separated list that identifies the IPMP groups that are on each node . The format of each entry in the list is netif@node. The replaceable items in this format are as follows:

    netif

    Specifies an IPMP group name, such as sc_ipmp0, or a public network interface card (NIC). If you specify a public NIC, Oracle Solaris Cluster attempts to create the required IPMP groups.

    node

    Specifies the name or ID of a node.

    This list is optional. If you omit this list, Oracle Solaris Cluster attempts to create the required IPMP groups.


    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.

    Note -  Oracle Solaris Cluster does not currently support using the adapter name for netif.
    resource

    Specifies the name of the resource.

  6. Create an application resource in the failover resource group.

    You can repeat this step to add multiple application resources (such as SSL and non-SSL based versions) to the same resource group.

    # clresource create -g resource-group \
    -t resource-type \
    -p Confdir_list=config-directory \
    -p Resource_dependencies=logical-hostname-list,.. \
    -p Port_list=port-number/protocol resource
    –g resource-group

    Specifies the name of the failover resource group into which the resources are to be placed.

    –t resource-type

    Specifies the type of the resource to add.

    –p Confdir_list=config-directory

    Specifies the location of the Oracle iPlanet configuration files. The Confdir_list file for failover services must have exactly one entry only. The config-directory must contain a directory called config. HA for Oracle iPlanet Web Server requires this extension property.

    –p Resource_dependencies=logical-hostname-list,…

    Specifies a comma-separated list of network resources that identify the logical hosts that the data service uses.

    –p Port_list=port-number/protocol

    Specifies the port number and protocol to use, for example, 80/tcp. Port_list for failover services must have exactly one entry only because of the one-to-one mapping rule between Port_list and Confdir_list.

    resource

    Specifies the name of the resource to add.

    The resource is created in the enabled state.


    Note -  Optionally, you can set additional extension properties that belong to the HA for Oracle iPlanet Web Server to override the default values of the properties. See Appendix A, HA for Oracle iPlanet Web Server Extension Properties for a list of these properties.
  7. Bring the failover resource group online.
    # clresourcegroup online -M resource-group
    resource-group

    Specifies the name of the failover resource group.
