An application server is a software framework that provides both facilities to create applications and a server environment to run them. Most application server frameworks contain a comprehensive service layer model, acting as a set of components accessible to the software developer through an API defined by the platform itself. For Web applications, these components are usually performed in the same running environment as their web server(s), and their main job is to support the construction of dynamic pages. However, many application servers target much more than just Web page generation: they implement services like clustering, fail-over, and load-balancing.

The timeout issue is not seen in the logs now after I set the system property as

 

<property name="jboss.as.management.blocking.timeout" value="600"/>

 

 

However still the war is not getting deployed with the below in the server.log

Three Reasons Why Backup is Strategic

Backup is strategic to your business because your data is strategic to your business. Without backup, your business will fail. This white paper explains why it is vital for you to design and immediately execute a backup strategy to protect 100 percent of your data.

Hi Expert,

One of our development team were trying to loading the data in their test database from their application portal.

They can attach file into the database but they got the following error.

"Timeout during database update. The operation has been accepted by the server and will usually complete successfully."

They are able to load the file successfully but don't want application user to see this.

Here is my question, is there any option to set up timeout for the database level. They set up the file size from application side only for 20 MB


Please help

I have a current storage device which is clustered between 4 servers (2 application servers, and 2 database servers) There are 2 quorum disks one is attached to the database and the other is attached to the application sever - all of this resides on the SAN unit. I have 10 disks on my application server and 3 disks on my SQL server.  I've tried with the vendor 2 times and he's failed to migrate the cluster to the new storage unit.  Let me just say the new storage unit is set up exactly like the old storage unit and all the data is copied.  Can someone give me some information on the method to attach the new storage unit and detach from the old storage unit?  I think you have to break the cluster 1st because if you don't the drives will just fail over and apparently the contractor doesn't understand the concept of a cluster.

Hi Experts, we have a client with an old network system. There are 15 users in Sussex and 3 users in site London.
At the sussex main site there is 1 x sbs 2003 that runs active diretory, dns , dhcp, exchange (pop collector) and files. Also they have on this server sage payroll.

They also have 1 x windows 7 machine that runs sage adm (multiple different versions) and Iris.
Ix windows 7 machine also servers as a windows RDP server for the London office , 3 users.
They log into access files and the apps.

They are considering going to Office 365 and want to explore how they can have a better , secure system.
We are looking at proposing Server 2012 DC , and an Apps server for Sage, Iris and a documents storage program they use.
We are considering a VM server to run this , just wondered if we could get some feedback and some advice on best approach for this.

Hi All,

Please can someone tell me in layman term the best practice for a simple optimal performance for setting up network connections within Active Directory Site and Services. Currently to me it looks overkill with connections to each sites, not sure if this is good for replication or bad? Please try not to send me complicated links as I've already googled some and it makes my head hurt.

We have -

Site 1 - 100MB MPLS with 2x DC's
Site 2 - 100MB MPLS with 2x DC's

Site 3 - 10MB MPLS with 1x DC
Site 4 - 10MB MPLS with 1x DC

Thanks in Advance!

I've inherited someone's undocumented setup, and I'm a first-timer who is learning OTJ.  Weblogic version is 10.3.2; the services are Forms and Reports. My startup sequence, at a high level, is to fire up three admin servers (startWebLogic), then three node managers (startNodeManager), followed by numerous user projects (startMangedWebLogic). Lastly, I start my oid and fr instances with opmnctl.

I've become a little familiar with the startup sequence, why Admin has to load before the managed services. Yea. My goal is to understand why there are three admin servers and three node managers (set up by persons before me, long since gone). The domains are for OID, OAM, and FR (forms).

Please help me understand whether this arrangement is healthy and if not, how to improve on it.  TIA.

We are migrating away from a key production application, but I am wondering how to handle support for the remainder of the year?

If you have done any major application migrations, how have you handled support on the legacy system?
- only break/fix support?
- no new reports?

What did you find as guidelines that worked for you?

We're running a XA 6.5 environment, and I've just built a series of new VMs and added them to the existing farm.

I am able to see the new servers within the farm and have verified that the application servers are all same version (6.5), same OS Win2k8R2, same Hotfix XA650W2K8R2X64R03.  However the XML brokers (we have 3) are R04.  My first guess would be to verify that all the Hotfix packs were the same, however, when I try and launch applications from the old farm (R03), everything works normally with the XML brokers (R04).  I don't want to convert the XML brokers (R04) to a different hotfix pack (R03) and break the old production environment.  So why can't the new servers work with the XML brokers?

I have verified that the new application servers have R03 just the same as the old farm, however I am unable to publish applications from any of the new servers.

When I attempt to launch an application from one of the new servers, I see the following error messages in the WI:

1. An error occurred while attempting to read information from the Citrix servers: An existing connection was forcibly closed by the remote host. This message was reported from the XML Service at address http://SERVER1.domain:8080/scripts/wpnbr.dll [com.citrix.xml.NFuseProtocol.RequestAddress].

Hello Experts - I have just started a new contract job as a Sys Admin but there is no hand-over as the previous person has left already. There is very little documentation, the docs all look out of date or incomplete & it's a very small team so no-one within the team can tell me exactly how many applications we have (50'ish best guess!!), what they are, versions, etc, etc. Not ideal.

I really need to find a way to audit my VMWare ESXi V5.5 environment & give me detailed info on my applications, the infrastructure side is much easier to work out. The type of application info I need is what apps & the versions, what databases are they using, size of databases, maintenance/backup schedule info & most crucial of all - what application interfaces do I have. I don't know what (if any) middleware they have so the application interface info is the biggest concern.

I'm thinking apps such as LabTech, SpiceWorks & Puppet Enterprise run as a 30 day trial will give me infrastructure info but I don't know if they also provide that detailed application audit info I need. I know VMware vSphere can give me infrastructure info on the VMware farm but I don't think it provided application info but I could be wrong.

My on premise VMware farm has 62 servers Windows 2008 & 2012 & RHEL V6. I know my databases are a mix of MS SQL & Oracle. The apps cover ERP, Payroll, Retail, Business Intelligence, Supply Chain, Manufacturing plus the usual Microsoft AD, Exchange, etc, etc.
