Priority for Concurrent Program

Posted on September 29th, 2010 by Sanjit Anand |Print This Post Print This Post |Email This Post Email This Post

If you are working in big user environment, user always complain there request get stuck or takes time to start processing. Majority of time Support team cann't do anything, unless waiting or asking DBA to check the server performance.

There is couple of option you can try , if you know a demanding user and there request name( Concurrent Program) he/she always want in periority.

dgreybarrowOptions 1: If you know what particular program user required in priority.

In oracle EBS you need to set the priority of specific users so that when they run specific reports, those reports should be run on high priority. The steps are very simple:

  1. Go to Sysadmin Responsibility and go to menu Profile > System.
  2. Make sure Site and User boxes are checked.
  3. Select the user name for the user for whom you want to increase the priority
  4. Enter the following within the Profile box and click on Find: Concurrent:Request Priority
  5. Change the priority for the user as you see fit (1 is highest, 99 is lowest, 50 is the default) , Save and exit.

Concurrent Priority1

dgreybarrowOptions 2: You know the Program name, and want to make execution in priority

The steps are very simple:

  1. Login system administrator /Application developer and go to define concurrent screen
    Under Concurrent >> Program >> Define
  2. Find the Program name whose priority you wish to change for ex. "Payable Transfer to GL"
  3. On this screen you can set priority of this request by entering value in "Priority" field( as mark in red) (1 is highest, 99 is lowest, 50 is the default) , Save and exit.

Concurrent Priority

dgreybarrow Oracle definition for Priority

Priority is used to indicate the priority that the concurrent request will be assigned when it is submitted. If you do not assign a priority, the user's profile option Concurrent:Priority sets the request's priority at submission.

dgreybarrow Profile : Concurrent:Request Priority

This displays the default priority number for your concurrent requests. Only a system administrator can change your request priority.

Requests normally run according to start time, on a "first-submitted, first-run" basis. Priority overrides request start time. A higher priority request starts before an earlier request.

Priorities range from 1 (highest) to 99 (lowest). The standard default is 50.

Users can see this profile option, but they cannot update it. This profile option is visible and updatable at all four levels.

Cloud Computing – Big Buzz in IT

Posted on September 28th, 2010 by Sanjit Anand |Print This Post Print This Post |Email This Post Email This Post

Cloud Computing technology and services have been witnessing a lot of attention for the past couple of years. There are significant interests already shown by the enterprises towards adoption of Cloud Computing Technology and Services.

dgreybarrow What is Cloud computing?

Cloud Computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "Cloud" that supports them.Wikipedia

If you have IT background, you can understand like Cloud Computing is the use of massively scaled offsite IT resources assembled virtually, accessed over the internet, contracted on demand in real-time or near real-time on a pay-per-use or subscription basis, where the workloads are shared among multiple customers.

It is method to address scalability and availability concerns for large scale Applications.

A cloud is a pool of virtualized computer resources. A cloud can:

  • Dynamic computing infrastructure
  • IT service-centric approach
  • Self-service based usage model
  • Minimally or self-managed platform
  • Consumption-based billing

Critical attributes of Cloud Computing are:

  • Service Based: Defined interfaces between consumers and providers
  • Scalable and Elastic: Scales to add or remove resources as needed
  • Shared: Shares a pool for economy of scale
  • Metered by use: Tracks usage and enables multiple payments model.
  • Internet Technology: It is delivered through internet technology

Essentially IT infrastructures hosted by third parties that are easily accessible by organizations to increase capacity and capabilities without having to invest in new hardware, software or employees.

dgreybarrowCloud Overview and Considerations

According to the U.S. National Institute of Standards and Technology, cloud computing consists of five essential characteristics, three distinct service models, and four deployment models.

  • Essential Characteristics
    • On-Demand Self-Service
    • Resource Pooling
    • Rapid Elasticity
    • Measured Service
    • Broad Network Access
  • Service Models
    • Software-as-a-Service (SaaS) :Organisations can access a wide range of applications,operating systems and services. These services frequently support collaborative working and the interlinking of services (mash ups)
    • Platform-as-a-Service (PaaS) :All of the facilities required to support the complete life cycle of building and delivering Web
      applications and services is entirely available from theInternet
    • Infrastructure-as-a-Service (IaaS):
  • Deployment Models
    • Public Cloud
    • Private Cloud
    • Community Cloud
    • Hybrid Cloud

At the core, Cloud Computing has three flavors of “as a Service.”

Cloude

 

  • Software as a Service (SaaS)

Here is defination as per NIST

"The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure… accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email)." [Source NIST Definition of Cloud Computing v15]

User can access software or an application hosted as a service across web using through a web browser. It is a cost effective solution and also easily deployed. Vendors may host the application on their own web servers or download the application to the consumer device like

  • Utility Computing
  • Virtual Servers

Typical Example are example are Salesforce.com, Gmail.com ,WebEx, Google Docs, acrobat.com

For non IT people, you can understand as , you will never buy another software license or do another implementation or upgrade if you have an alternative that is pay–as–you–go and get–what–you–need.

  • Platform as a Service (PaaS)

This category of things we can “rent” from a Cloud Computing provider.

User can develop application over web without the requirement to physically installing the software locally. Complete platform is hosted remotely and then delivered to the users directly on subscription basis.It is transparent as it encapsulate the required software and exposes the user only services.

Cloud computing platforms

  • Elastic Compute Cloud (By Amazon)
  • Azure (By Microsoft)
  • Force.com (Salesforce.com)
  • Blue Cloud (By IBM)
  • Suiteflex (By NetSuite)
  • Apps Engine (By Google)
  • Infrastructure as a Service (IaaS)

No need to buy and maintain the servers and storage space. It can be rented now as per the new services provided by the Cloud
computing. Infrastructure as a Service (IaaS) eliminates the operational cost and at the same time it also provides most of the features and functions found in the traditional Enterprise Application Integration technology.

This category is Infrastructure as a Service, which offers lower–level capabilities like storage and processing power.

Typical example are Amazon Web Services,Google Base, SAVVIS,Terremark Worldwide,Gogrid,Sun Grid, Compute Utility

Cloud Computing works on “pay–as–you–go and get–what–you–need” model.

dgreybarrow What are the benefits of Cloud?

Pressures to decrease IT costs and increase agility are driving organisations to consider cloud computing services.

Organisations are concluding that the traditional packaged software model is outdated and are considering cloud computing with other forms of outsourcing

Cloud computing is being driven by many urgent priorities:

  • Reduce amounts of IT capital equipment spending
  • Gain flexibility and speed in implementations
  • Leverage IT technology evolution
    • Rapidly changing technology standards and practices are driving enterprise to consider
    • cloud computing as a viable alternative
    • Mobile and flexible working patterns

dgreybarrow Future with Cloud Computing

This is still at very early stage.

  • Cloud computing growth is projected at 20% in the next few years
  • Organisations will move to cloud services out of economic necessity
  • Google and Amazon will expand their footholds among startups
  • Microsoft cloud services will gain strength among .NET users
  • Major application vendors, such as Oracle, SAP, Workday planned to introduces new cloud services
  • Cloud computing startups will continue to be funded and drive innovation
  • Emerging data security standards in the cloud will increase adoption by larger organisations
  • Development of APIs
    • Red Hat's Delta Cloud
    • Citrix's Xen Cloud
    • Amazon Web Services API
    • VMware's VCloud

Techies who are looking something to do great, keep watching this domain. This is surly getting hotter in another 2-3 yrs .
