Failover on zone cluster configured for apache on zfs filesystem takes 30 M

Hi all
I have configured zone cluster for apache service, i have used ZFS file-system as high available storage.
The failover takes around 30mts which is not acceptable. my configuration steps are outlined as below
1) configured a 2 node physical cluster.
2) configured a quorum server.
3) configured a zone cluster.
4) created a resource group in the zone cluster.
5) created a resource for logical hostname and added to the above resource group
6) created a resource for Highavailable storage ( ZFS here) and added to the above resource group
7) created a resource for apache and added to the above resource group
the failover is taking 30mts of time and shows "pending offline/online" most of the time
I reduced the number of retry's to 1 , but of no use
Any help will be appreciated
Thanks in advance
Sid

Sorry guys for the late reply,
I tried to switch the owners of RG to both the nodes simultaniously,which is taking reasonable time.But the failover for a dry run is taking 30mts
The same setup with SVM is working fine, but i want to have ZFS in my zone cluster
Thanks in advance

Do I need 3 machines for Sun Two-Node Cluster HA for Apache?

The vendor is trying to set up a Sun Cluster HA for Apache and said it requires a dedicated machine
for monitoring purpose(The Sun Cluster HA for Apache probe??). Is this monitoring machine mandatory and have to be dedicated for that purpose? And can I use 1 machine to monitor more than 1 cluster? Because the vendor requires 2 extra machine to monitor 2 set of 2-node cluster..and the document I read from Sun only mentions the 3rd machine is required for admin console.
Also, if I only have 2 node cluster, can I configure Apache as a scalable + failover service at the same time or I have to choose either one? Thanks!!

Incorrect. You can set up a Solaris Cluster on a single node if you wish although two nodes give you redundancy. The probe for Apache runs from the node on which Apache is executing.
If you have a two node cluster you could have multiple implementations of Apache: fail-over and scalable. You can mix them until you run out of resources: CPU, networking bandwidth, IP addresses, etc.

Httpd.conf configuration for Apache plugin

Hi,
anyone have a sample httpd.conf file configured for proxy to WL 6.1, but only
limited content?
Meaning : static content is served on the apache (gifs, html, ...) and ALL THE
REST is proxyd to WL...
The WL part i guess is like this :
<IfModule mod_weblogic.c>
WebLogicCluster x:7001,y:7001
CookieName WebLogicSession
MatchExpression *.*
</IfModule>
Its the Apache part I cant find any info on.
Thanks in advance.

try this:
<IfModule mod_weblogic.c>
WebLogicCluster x:7001,y:7001
CookieName WebLogicSession
MatchExpression /SERVLET_NAME
MatchExpression *.jsp
</IfModule>
That should do it ... but you should know that there are more problems down that way ...

Zone Cluster: Creating a logical host resource fails

Hi All,
I am trybing to create a logical host resource with two logical addresses to be part of the resource, however, the command is failing. Here is what I run to create the resource:
clrslh create -Z pgsql-production -g pgsql-rg -h pgprddb-prod,pgprddb-voip pgsql-halh-rs
And I am presented with this failure:
clrslh: specified hostname(s) cannot be hosted by any adapter on bfieprddb01
clrslh: Hostname(s): pgprddb-prod pgprddb-voip
I have pgprddb-prod and pgprddb-voip defined in the /etc/hosts files on the 2 global cluster nodes and also within the two zones in the zone cluster.
I have also modified the zone cluster configuration as described in the following thread:
http://forums.sun.com/thread.jspa?threadID=5420128
This is what I have done to the zone cluster:
clzc configure pgsql-production
clzc:pgsql-production> add net
clzc:pgsql-production:net> set address=pgprddb-prod
clzc:pgsql-production:net> end
clzc:pgsql-production> add net
clzc:pgsql-production:net> set address=pgprddb-voip
clzc:pgsql-production:net> end
clzc:pgsql-production> verify
clzc:pgsql-production> commit
clzc:pgsql-production> quit
Am I missing something here, help please :)
I did read a blog post mentioning that the logical host resource is not supported with exclusive-ip zones at the moment, but I have checked my configuration and I am running with ip-type=shared.
Any suggestions would be greatly appreciated.
Thanks

I managed to fix the issue, I got the hint from the following thread:
http://72.5.124.102/thread.jspa?threadID=5432115&tstart=15
Turns out that you can only define more than one logical host if they all reside on the same subnet. I therefor had to create 2 logical host resources for each subnet by doing the following in the global zone:
clrslh create -g pgsql-rg -Z pgsql-production -h pgprddb-prod pgsql-halh-prod-rs
clrslh create -g pgsql-rg -Z pgsql-production -h pgprddb-voip pgsql-halh-voip-rs
Thanks for reading :)

But I have enough FS space. I increased the virtual HDD to 25GB on each node. After global cluster installation, I still have 16GB free on each node. During the install I constantly check the free space and it should be enough (only about 500MB is consumed by downloaded packages, which leaves about 15.5GB free). And every time the installation fails at "apply-sysconfig checkpoint"...

Hello,
First of all, I detected a mistake in my previous config: instead of adding an ipmp, a "simple" NIC was added to cluster. I rectified that (I created zclusteripmp0 ipmp out of net11):

Dynamic Configuration for two file adapters communication channels

Hello Experts!!!!!!
     In one of the interface in my landscape, I am using two file adapters for creating two files with different names and at two different destination on F.T.P.
However the receiver service for both the communication channel are same.
In message mapping I am using multi mapping to create two files out a single message.
Now i have a requirement of changing file path and file name using dynamic configuration for both the comm channel.
When i doing dynamic coniguration for both the comm. channel. My interface is creating two files but with same name and on same destination which is set for second communication channel through dynamic configuration.
Here, I guess the second dynamic configuration is over writing the first dynamic configuration and hence creating two files with same name and at same destination.
Please suggest, if separate dynamic configuration for separate communication channel of same receiver service can be done?
Thanks & Regards,
Amol

Thanks for your prompt responses!!!!!
    Is there any way, By which in dynamic configuration I can find out the communication channel name and then change its parameter.
I mean if iam using say comm. channel A and B.
Then in dynamic configuration for A, I will first take communication channel A by calling it and then change its path/file name.
and then do samething for comm. channel B in its dynamic conf.
Regards,
Amol

How to configure Oracle database in a failover zone cluster

Setup: Oracle database and zone configured on highly available local filesystems.
Two node cluster.
Oracle database running inside the zone.
Note: I dont have a zone cluster.
1. I need to make the zone and the oracle database highly available.
2. Can I configure the Oracle Data service directly to run in the zone or will it involve creating sczsh_config script to do the same.
I have been going through the guides and searching over the net, but haven't found any help so far. Its so much simpler to configure this environment in Veritas cluster. Hope I find some help here.
TIA,
Sudhir

The Oracle Solaris Cluster concepts guide has some information on which zone model to choose:
http://docs.oracle.com/cd/E18728_01/html/821-2682/gcbkf.html#scrolltoc
When managing a Solaris zone with the HA Zones agent, the cluster basically regards the non-global zone as a blackbox.
As such you can either start the Oracle database as part of the runlevel/SMF startup of the non-global zone, or you can use the sczsh or sczsmf component and use your own scripts to start, probe and stop the Oracle database.
Usage of the standard HA Oracle data service is not supported in combination with the HA Zones agent.
If you require a more fine grained control of services running in non-global zones, why not setup a zone cluster and then having HA Oracle failover the Oracle database between non-global zones?

Scalable Apache service in a zone cluster

Hi,
I have set up a 2-virtual node zone cluster (on a physical 2-node cluster).
I am trying to set up an apache resource group (scalable) on the two nodes, but I don't get the zone cluster nodes as valid options to use while running clsetup and/or the web gui wizard.
They only see the two global zones and one failover zone I have configured on the cluster.
Is there no way to set up a scalable apache service on the zone cluster? Any help will be appreciated.
Thanks,
D

Never mind...I had to run the clrg,clrs and clressharedaddress commands from within the zone cluster nodes and not from the global.
It's going to take a while to come to terms with the clustering within the cluster.

Best practice configuration for SQL 2014 to achieve HA when hosted on Hyper-V 2012R2 cluster

Hi,
I've had a hunt around but so far I've not found a conclusive answer to my question. I am currently moving from a SQL 2008R2 (physical tin) failover cluster to a virtual environment build on Hyper-V 2012R2. I am building everything with SQL 2014
SP1.
I want to achieve the same level of high availability that I currently have and at the same time make sure that I can replicate (DR) data offsite (Azure) in the future. I have two options with SQL which are clustered instance (basically the same as
I have now) or AlwaysOn Availability Groups for database level HA.
I am unsure which is the best method to use when the SQL nodes are highly available guests on Hyper-V, trying to imagine how the guests will all move around in the case of a host server failure is a bit mind boggling to say the least.
I am leaning towards a instance failover but I would appreciate any input/advice etc.
Thanks
Rob

Hi Rob,
To start with I will not be installing SQL Server 2014 with SP1, as SP1 has bugs and Microsoft has disabled its download. See reference: http://www.eweek.com/database/microsoft-halts-sql-server-2014-sp1-downloads.html
With regards, I would go for AlwaysOn Availability Groups configuration, because it has several benefits:
You will get same amount of high availability you normally get with native cluster configuration, if you use AlwaysOn configuration. However, AlwaysOn configuration provides more granular high availability, and fail-over are invisible to the application,
if you using Availability Group listener to connect to server.
You can offload read-only workloads to secondary replica.
You can perform transaction log backups on secondary replica.
Reduce production downtime during patching or other planned work on the server.
So in short, you should use AlwaysOn configuration.

SQL Server 2012 Failover Cluster configuration questions

Hi,
I have few questions on , SQL Server 2012 Failover cluserting pleasse provide suggestions:
1) In SQL Server 2012 is there a configuration for active / passive Failover Cluster installation? If so how is it done? if you could provide any links or articles that would help.
OR
Is this been replaced by Always ON Availability Groups?
2) Also in our environment we have done active/active installation but at a time my understanding is only node has the ownership to the shared storage versus both the nodes, is that correct? If not please provide an explanation?
Any additional information would be valuable in clearing my doubts?
Thank youy
Malini=

Hi malinisethi,
If you install SQL Server in a cluster and configure Active-Passive cluster. In the first node, select “New SQL Server Failover Cluster installation” option , when we are installing Active-Passive cluster, we have to specify one virtual/network name. (Note:
For Active-Active clustering you have specify different network names as per the number of nodes). on the other nodes is similar to installing on the first node except that we have select the Add Node to a SQL Server failover cluster option from the initial
menu. For more information, there is a similar issue about SQL Server 2008 Active-Passive/Active-Active cluster installation, you can review the following article.
http://sqldbpool.com/2009/10/07/sql-server-2008-active-passive-cluster-installation/
About Active/Active SQL Cluster, two clustered SQL Server instance are created in different nodes. Then apply Active /Active configuration of both instance. There is an example about creating an Active/Active SQL Cluster using Hyper-V. you can review the
following article.

Hyper-V Failover Cluster Configuration Confirmation

Dear All,
I have created a Hyper-V Failover Cluster and I want you to confirm if the configuration I have done is okay and I have not missed
out anything that is mandatory for a Hyper-V Failover Cluster to work. My configuration is below:
1. Presented Disks to servers, formatted and taken offline
2. Installed necessary features, such as failover clustering
3. Configured NIC Teaming
4. Created cluster, not adding storage at the time of creation
- Added disks to the cluster
- Added disks as CSV
- Renamed disks to represent respective CSV volumes
- Assigning each node a CSV volume
- Configured quorum automatically which configured the disk witness
- There were two networks so renamed them to Management and Cluster Communication
- Exposed Management Network to Cluster and Clients
- Exposed Cluster Communication Network to Cluster only
5. Installed Hyper-V
- Changed Virtual Disks, Configuration and Snapshots Location
- Assigned one CSV volume to each node
- Configured External switch with allow management option checked
1. For minimum configuration, is this enough?
2. If I create a virtual machine and make it highly available from hyper-v console, would it be highly available and would live
migrate, etc.?
3. Are there any configuration changes required?
4. Please, suggest how it can be made better?
Thanks in advan

Hi ,
Please refer to following steps to build a hyper-v failover cluster :
Step 1: Connect both physical computers to the networks and storage
Step 2: Install Hyper-V and Failover Clustering on both physical computers
Step 3: Create a virtual switch
Step 4: Validate the cluster configuration
Step 5: Create the cluster
Step 6: Add a disk as CSV to store virtual machine data
Step 7: Create a highly available virtual machine
Step 8: Install the guest operating system on the virtual machine
Step 9: Test a planned failover
Step 10: Test an unplanned failover
Step 11: Modify the settings of a virtual machine
Step 12: Remove a virtual machine from a cluster
For details please refer to following link:

Apache configuration for weblogic

Hi All
I need your help for configuring my apache for weblogic. Actually we created 2 non clustered server and deployed an application on them. Now we want to achieve the load balancing on the apache side. So, I am just wondering what exactly I should write down in http.conf to achieve it.
e.g in clustered environment we give :
<Location /process>
WebLogicCluster abc:7210,xyz:7210
SetHandler weblogic-handler
</Location>
where abc and xyz are cluster members.
If you have any idea then please share it.
Thanks in Advance.

To configure Apache Plug-in with Weblogic Server, follow the steps below
1. To make Apache server run on a different port say 8080, other than the dafault (80).
Modify the httpd.conf present at
D:\Program Files\Apache Group\Apache2\conf
Change the Listen port to 8080 in the httpd.conf file
Listen 8080
2. Copy the mod_wl_20.so from \wlserver_10.3\server\plugin\win\32 to
D:\Program Files\Apache Group\Apache2\modules
3. Apply the plug-n module by adding these in the httpd.conf file
LoadModule weblogic_module modules/mod_wl_20.so
<Location />
SetHandler weblogic-handler
</Location>
<IfModule mod_weblogic.c>
WebLogicCluster localhost:7003,localhost:7005
Debug ON
WLLogFile c:/temp/wlproxy.log
WLTempDir c:/temp
</IfModule>
4. Restart the Apache Server

Cannot save configuration for zone files

I'm migrating from 10.3 to 10.4.9. The 10.4.9 system is on a new hard drive so it is a fresh install. I have no problem setting up the BIND config manually from the command line but I like to use Server Admin to start and stop the server. When I noticed I was having problems resolving my servers domain/subdomains, I used Server Admin to take a look at what was going on.
The problem I seem to be encountering is that Server Admin shows that the zones exist but it does not display any of the zone data in the window to the right of the zone list. I did a quick check on the zone files and found them to be configured correctly. When I tried to edit and then save the configuration using the Server Admin GUI I receive an error telling me that the zone had no name and that the configuration could not be saved.
Just to test things out a little bit, I dragged the DNS configuration file from the 10.3 config from the Server Admin Applition, rebooted the system back into 10.4, and dropped that configuration back onto the application window. After this process I can see the zone data in the right hand window but when I click the save button I receive the same error.
My only reference for 10.4 is the Apple Training Series: Mac OS X Server Essentials which describes the Server Admin GUI for the DNS functions and the associated files in a manner that I am familiar with but which are significantly different then what is actually appearing in the Server Admin application for 10.4.9.
Does anyone know what could possibly be wrong?
Thanks
XServe G4 Mac OS X (10.4.8)

Unfortunately, there are a number of flaws with the Server Admin DNS tool that absolutely require you to modify the files manual. For instance, you cannot properly set up MX records is the zone you are working on is NOT responsible for the mail server. In other words, you can't set up MX records. Also, the name server text fields are bugged in a way that makes it extremely difficult to add more then one name server. The tool is useless until these problems are fixed.
Basically, as you said, I used the dns tool to set up the files, then edited them manually in order to get them into a functional state. I just have to make sure that I don't ever use the tool to edit the configuration as it will blow away any changes that were made manually.
FYI The Server Admin web tool for Apache is also just as annoying, deleting data that has been added manually.
