Configure iws on Sun cluster???

Question

I have installed sun cluster 3.1.On top of it I need to install iws(sunone web server).Does anyone have document pertaining to it?
I tried docs.sun.com , the document there sound greek or latin to me
Cheers

Answer 1

Just to get you started:
3) create the failover RG to hold the shared address.
#scrgadm -a -g sa-rg (unique arbitrary RG name) -h prod-node1,prod-node2 (comma seperated list of nades that can host this RG, in the order you want it to fail over)
again - #scrgadm -a -g sa-rg -h prod-node1,prod-node2
4) add the network resource to the failover RG.
# scrgadm -a -S (telling the cluster this is going to be a scalable resource, if it were failover you would use -L) -g sa-rg (the group we created in step #3) -l web-server (-l is for the hostname of the logical host. This name (web-server) needs to be specified in the /etc/hosts file on each node of the cluster. Even if a nodfe is not going to host the RG, it has to know about the LH (logical hosts) hostname!)
again - #scrgadm -a -S -g sa-rg -l web-server
5) create the scalable resource group that will run on all nodes.
#scrgadm -a -g web-rg -y Maximum_primaries=2 -y Desired_primaries=2 -y RG_dependencies=sa-rg
-y is an extension property. Most resources use standard properties, other "can" use extension properties, still others "must" have extension properties defined. Maximum_primaries says how many nodes you want instance to run on at the most. Desired_primaries is how many instances you want to run at the same time. For an eight node cluster, running other DS's you might say, Maximum_primaries=8 Desired_primaries=6 Which means an instance could run on any node in the cluste, but you want to try to make sure there are nodes available for your other resource so you only want to run 6 instance at any given time, leaving the other two nodes to run your other DS's.
You could say Max=8 Desired=8 it's a matter of choice.
6) create a storage resource to be used by the app. This tells the app where to go to find the software it needs to run or process.
-a=add,-g=in the group,-j=resource name, needs to be unique and is arbitrary, -t resource type installed in pkg format earlier, and registered, -x= resource type extension property (a -y extension property could be used for a RG property or a RT property) -x is only for a RT property. /global/web is defined in the /etc/vfstab file with the mount options field specifying global,logging (at least global, maybe logging) (note you do not specify the DG, just mounts from storage supplied by the DG, because multiple RG's may use storage from the same DG)
#scrgadm -a -g web-rg -j web-stor -t SUNW.HAStoragePlus (HAStoragePlus provides support only for global devices and file systems) -x Affinityon=false -x FileSystemMountPoints=/global/web
7) create the app resource in the scalable RG.
-a=add, -j new resource -g (in the group) web-rg (created in step #5) using the type -t SUNW.apache (defined in step #2, remember the pkg installed was SUNWscapc, SUNW.apache is a made up name we are using to use apache for possibly multiple resource groups. Each -j (resource name must be unique, and only used once) but each -t (resource type, allthough having a unique name from other RT's can be used over and over again in different resources of different RG's.) Bin_dir (self explanitory, where to go to get the binaries) Network_Resouces_Used=web-server (created in step #5, again is the hostname in the /etc/vfstab for the logical host, the name the clients are going to use to get to the resource.) Resource_Dependencies=web-stor (created in step #6) saying that apache-res depends on web-stor, so if web-stor is not online, don't bother trying to start apache because the binaries won't be there. They are supplied by the storage being online and /global/web being mounted up.
#scrgadm -a -j apache-res -g web-rg -t SUNW.apache -x Bin_dir=/usr/apache/bin -y Scalable=True -y Network_Resources_Used=web-server -y Resource_dependencies=web-stor
8) switch the failover group to activate it.
#scswitch -z -g sa-rg
9) switch the scalable RG to activate it.
#scswitch -z -g web-rg
10) make sure everything got started.
#scstat -g
11) connect to the newly, cluster started service.
