Agent in active/passive environment

All:
Are there any Best Practices docs for installing and maintaining the agents
in an active/passive cluster ?
Should I see both nodes in GC ?
Thanks

Nope. Everything works fine even on my VPN via relatively slow DSL. I normally copy large files locally to work on them and then copy them back to the server, but that's just because I have a slow connection.

Anyone is using Active-Passive in BPEL environment??

Disaster Recovery: Active/Passive Mail Flow

Hello. I am planning to deploy an active/passive server environment for Exchange 2013. Here's what I plan to achieve:
EXCHANGE-A - on production site, active (all mail flow goes through here), member of DAG
EXCHANGE-B - on disaster recovery site, passive (mail flow goes through here ONLY when activated), member of DAG
I have tried disabling all receive connectors on EXCHANGE-B, however that causes OWA to delay sending messages for around 20 seconds (messages stuck in Drafts folder before being sent out). I have also tried disabling Exchange Transport services on EXCHANGE-B
but to no avail.
Is it possible to achieve active/passive mail flow server environment? What is the best way to achieve this? I appreciate any leads on this matter.

Hi ,
Shadow redundancy configuration is available on the transport config and any change applied on the transport config parameters will get applied to all the transport servers in our organisation and it not specific to the server level.
Command
to disable the shadow redundancy feature :-
set-TransportConfig -shadowredundancyenabled $false
Note : Above command will disable the shadow redundancy feature for your entire organisation.

[b]Managing Active/Passive Cluster.[/b]

Hi,
We are having active passive cluster
environment and we are running webMethods on
it.
The problem we are having is whenever we do
any changes we need to do a failover and then
do the same task on the passive one as well.
Can anybody help how to make this thing
automatic so that we deploy any package/fixes
on webmethods and should get replicated on
the passive one.
Thanks,
Amit.

If you are manipulating data-files, that do not affect the Application (in this case webmethods) then simply use the cluster console, which allows you to perform updates on multiple hosts at the same time.
Alternatively if you are making changes to the application itself then, does the application management software ( I am not that familier with webmethods) not allow you to distribute changes across an application domain, ie. using the application tools and not the underlying cluster framework.

Active Passive Vs Active Active

Hi All,
How much more effort it requires to failover or get up and ready with passive node, if Active Passive strategy is followed rather than Active Active just for saving on licenses.
Note : High availability is not a concern.
thanks,

Be clear what the policy means. RAC is normally considered an ACTIVE/ACTIVE solution since all nodes in RAC are actively processing. In an ACTIVE/PASSIVE setup by contrast one or more nodes are actively processing whilst others are standing by ready to take over the workload in the event of failure of the primary. Physical Standby, Failsafe and non-oracle clusters are often Active/Passive. You may also check if the policy comes from a sqlserver centric view of the world where you split the sqlserver databases between different nodes, so that although for any given sql database the solution is active passive, you don't 'waste' the resources of some nodes just waiting to take over, but rather run other databases on them.
Your description of ACTIVE/ACTIVE seems to rather correspond to a Stretch Cluster http://www.oracle.com/technology/deploy/availability/pdf/1126_Ray_WP.pdf has a good overview of what this means. I'd be surprised if the policy was really to put all databases on just about the most expensive hardware and software solution available, but I'm used to surprises in the world of corporate policies.

RMAN for active passive 10g R2 RAC

Hi,
I am having 10g R2 Active-Passive RAC setup.
in this environment,If I am taking the backup using RMAN,
how can I handle the failover?
In active-active instance, if channel allocated to one node is failed, backup will be completed from channel allocated to other node.
how can i handle the failover in active-passive RMAN backup??/

What was the reason you went for active/passive RAC setup ?
--> this is requirement.
I thought cluster could achieve the same thing.
1) How can we achive active/passive setup by using cluster?
2) In RAC active/passive configuration and Cluster setup, which one is good option?
3) Any URLs on this topic
Thanks in Advance....

Active/Passive Solution With 9iAS R2

Hi All,
Question about active/passive 9i AS R2 solutions. My developers is looking for a solution where they can deploy OC4J packages on one node(the passive node) and then when verified make it the active node and deploy to the other node. The system contains 2 webcache servers, two single node 9i AS servers(only one node is used) and a db server 9i R2 with the Infrastructure db on it and prod database. OID is on a single node and we do not use SSO, on the same node we have reports and discoverer.
So, I want to go from a single node iAS solution to using both nodes where one is passive and is used to deploy new code on and to verify it, and then switch it to be the active node. Is there a way to do this without clustering the AS nodes and how would that be configured. If making this on two single nodes is not possible, how would a two node cluster config with manual switch look like. Or, is there an other way to do this?
Regards,
Krister

Uhm... you can do something like you say with WebCache.
Try this:
- set up a Webcache wich serves the 2 application server
- in Webcache set up the two application server as origin servers for your site
- map only one of the origin server to your site (site-to-server mapping) in WebCache
Then, you can use one application server as a pre-production environment, and the other as a production environment.
When you want to switch the two environments, all you have to do is to reconfigure the site-to-server mapping in Webcache and restart webcache.
Take in mind that by doing this, all the open sessions to your web application will die.
I think that a more usual test environment and production environment is safer.

Andrea

Installing Remote Blob Storage (RBS) Provider on Active/Passive cluster

We are implementing RBS for our SharePoint farm and have successfully got it installed and working for all Content Databases.
I've read a dozen or so guides but none of them cover installing on a clustered SQL environment and I need to install the RBS provider on the passive node but cant see any guides that mention it although its stated Clustering is supported.
Can anyone tell the correct way to install it on the passive node?

Hi Dr_Sanchez,
According to
this blog, it is supported to install remote blob storage provider on SQL Server active passive cluster. You could follow the installation steps in that blog. If you get an error like this:
Cannot use file 'c:\Blobstore' for clustered server. Only formatted files on which the cluster resource of the server has a dependency can be used. Either the disk resource containing the file is not present in the cluster group or the cluster resource of
the Sql Server does not have a dependency on it.
Then please replace 'c:\Blobstore' with the volume\directory which resides in the same group in the Cluster Administrator as the SQL Server resources.

Michelle Li

Install of Data Services as active/passive behind F5 load balancers

I currently have two RedHat 5.5 x86_64 hosts, SAP_DS1 and SAP_DS2, and 1 database, Oracle RAC 11g and 1 F5 LTM load balancer sitting in front of the two hosts. The F5 load balancer VIP is set up as active/passive (fail-over) for the two hosts.
Will I need 2 local databases 1 central database or can I accomplish this with one local database?
Please advise on the recommended method for installing BOBJ DATA SERVICES XI 3.2 on two Linux hosts in an active/passive design.
Thanks

Can you Setup a Active Passive DFS namespace in the same site

Hi,
I would like to use DFS for profile replication. I know MS doesn't recommend it, but was wondering if you could setup DFS namespace in an Active/ passive contests in the same AD site. I think or what I can understand of DFS is that if the Fileserver is in
the same site it would select it randomly and you cant specify which server is the primary.
Basically what I want is to have users only access File server 1, but if this file server 1 goes down to be redirected to file server 2.
Thanks,
Shaun

You could have a read-only Replica but that really doesn't help you in terms of the automatic redirection thing. You could also set up a 2-node replication group and disable the referral for the folder(s) on one node like below:
However the "failover" would be manually Enabling, which I doubt fits the bill.
Otherwise, I'm not aware of any configuration of DFSR that allows you to do what you're talking about (maybe someone else will correct me.) HOWEVER, I suspect a design that fits your use case may be to create a DFS namespace that runs
on a file server cluster. That way if Node1 goes down, the cluster fails over, and the data continues to be available on Node2 when accessed via DFS.
If interested, there are a couple ways to approach DFS in combination with a cluster.
Configuration1: The cluster is configured to host the namespace as well as the folder targets (where the actual data is). CAVEAT - The cluster can only be configured as a standalone cluster.
Configuration2: Create a domain DFS namespace that resides on other servers.
\\domain\DFSRoot for example. Then point each of the leaves/folder targets to clustered shares. So you'd create a subfolder called "Profiles" that points to the clustered share that houses the profiles.
Just an idea. Hope this helps.

Error with concurrent users- Activation Passivation Bind variable ?

I have a programmatic view object based on procedure call that returns a ref cursor.
Application Module has a function that exposes get Method for this View object using client interface.
Everything works good until many users call the same Method ,for many concurrent users i got the below error intermittently :
JBO-27122: SQL error during statement preparation.
Attempt to set a parameter name that does not occur in the SQL: bussId
For 1 or 2 users this works perfectly fine.
bussId is a bind variable defined at View object of type Array.
I understand this should be because of activation/passivation as many users calling same function comes to picture.
To solve this I overloaded activateState/passivateState in View implementation for the bind var.
But i don't see those methods getting invoked ever.
I also enabled connection pool/AM pool and kept the default pool values high enough for concurrent users.
Nothing works .
Appreciate any help in this regard.

Non-domain user authentication against SSAS on Active/Passive Cluster

Hello,
We have an Active/Passive SQL Server setup (DB1 & DB2 Servers) connected to a cluster for SQL & SSAS. I have a web server not on the same domain that I am trying to authenticate with SSAS. This works OK if I set the website to impersonate
myUser and I add local account myUser as an Admin on SSAS for the active server (DB1). But when this fails over to DB2 then it fails to authenticate. SSAS won't allow us to add myUser as an admin for local accounts on both DB1 & DB2 as it errors
adding the second one. Could anyone advise how such a scenario should be approached?
We have tried creating a domain user too which DB1 & DB2 can of course both share but I don't think the web server can impersonate this with being not part of the domain.
Thanks.

Hi Jcorker,
According to your description, you need to access the SQL Serve Analysis Services database which is configured as cluster for SQL & SSAS from another domain, right?
In SSAS we can use the solution below achieve the requirement.
1.Create new domain account and impersonate the web site with that.
2.Create local user account on the analysis service with same exact username/password as like domain account created in the previous step.
However, you cannot create a local account with the same name on both servers. I have tested it on my local environemnt, we can create the same local account with the same name on both servers. In your scenario, if DB1 and DB2 on different server, you can
create a local account with the same name on both servers. Please post the detail errors, so that we can make further analysis.
Besides, SSAS only allows users of the same domain or trusted domains and it does not allow users from any domain except from these two. You can configure the trust relationship between the domains.
