Metalink Introduction

What is My Oracle Support?My Oracle Support provides personalized, proactive, and collaborative support across all Oracle products.

Metalink is a knowledge base for Oracle, it provides access to a vast amount Oracle resources such as: Articles, Notes, Forum, Patches, Support and a whole lot more. In order to get access to Oracle Metalink you must be a customer or partner. 
The great aspect of Metalink is that it allows one to find resources for troubleshooting purposes. I have resolved many issue ranging from functional setup to complex database issues.
Another, great feature is Oracle Support via Metalink. You can raise an SR or Support Request (previously known as a TAR) to Oracle Support for issues. As an Orace customer you can send an SR on almost every topic. I have taken advantage of this, for example I once submitted an SR on how to find a particular patch.

Oracle vs. SAP in five points!

As an ORACLE EBS consultant, we should aware of its counterpart –SAP and a few range of prospects that differentiate these two giants in today’s ERP market. Both SAP and Oracle eBusiness Suite (EBS) have strengths, weaknesses, and tradeoffs. Different clients have different needs, ranging from functional requirements, technical maturity, tolerance for risk, budget, and a host of other factors. 
So what are the differences between these two solutions? Although there are numerous variances in the detailed workflows and functionality of the solutions, there are five key high-level variables that we should aware of.
  1. Best of breed functionality vs. more tightly integrated modules. The software strategy of the two vendors could not be much different. While SAP has built a solution primarily from the ground up, Oracle has grown primarily through acquisition of best-of-breed point solutions. For example, Oracle has acquired Demantra for advanced sales and operations planning, Hyperion for financial reporting, and Siebel for CRM, while SAP has built much of this functionality into its core ECC and All in One ERP solutions.
  2. Product roadmap. SAP continues to build upon and enhance its core product offering, while Oracle is moving toward Fusion. While some may suggest that Oracle is more innovative or visionary in its technology direction, it also means that there may be more uncertainty with Oracle’s product lines. This is especially true for clients considering Oracle’s JD Edwards and Peoplesoft solutions.
  3. Flexibility. Although very powerful, SAP can be more difficult to change as a business evolves. This is both a strength and a weakness: it is tightly integrated and helps enforce standardized business processes across an enterprise, but it can be more difficult to modify the software to adjust to evolutions to core processes and requirements. Oracle’s best of breed approach, on the other hand, can allow for more flexibility to accommodate changing business needs, but this strength can become a weakness when it becomes harder to enforce standardized processes across a larger organization.
  4. Implementation cost, duration, and risk. Although both solutions typically cost more and take longer to implement than most Tier II ERP software, there are distinct differences between the two. Oracle has a slight advantage in average implementation duration and an even larger advantage in average implementation cost, at 20% less than SAP. SAP, on the other hand, has the lowest business risk of the two, measured via the probability of a material operational disruption at the time of go-live.
  5. Business benefits and satisfaction. This is perhaps SAP’s greatest strength. Although Oracle has the highest executive satisfaction level of all ERP vendors across the globe, SAP leads the pack in actual business benefits realized. Assuming the #1 reason most companies implement ERP software is to achieve tangible business benefits, this can be enough to justify SAP as a solid solution for many companies.
The key takeaway here is that, as with any ERP solution, SAP and Oracle both have their strengths and weaknesses. One solution may be the best fit for one organization, while not a good fit for others, even within the same industry. The only way to make sense of the pros and cons in a way that is meaningful to your organization is to engage in a robust ERP software selection process that considers your requirements, priorities, and competitive advantages to find the right fit.

Oracle Applications Documentation AIM Methodology – Introduction

Oracle A.I.M. Methodology encompasses a project management methodology with documentation templates that support the life cycle of an implementation. The life cycle methodology and documentation templates allows A.I.M. to be a very useful tool for managing implementation projects successfully.
The A.I.M. methodology can actually be used for any type IT software implementations however the value of A.I.M is within the documentation template. The software includes the documentation templates, manuals and an html website to manage these templates.

Here is a link for download: Download A.I.M. v3.1.0

Oracle Apps Fundamentals

Three environments, each with a different URL and different database instance. These are

  • Development environment; where developers usually have System Administrator responsibility and also the apps password. If not System Administrator then at least they should have access to “Application Developer” responsibility.

  • Testing environment; Developers usually do not and must not have apps password to this environment . This is where users sign-off customizations or even setup changes.
  • Production environment; This is where the business runs

When you logs in the user is authenticated against a table named fnd_user for the username and password.
Oracle internally uses a login named GUEST, prior to invoking validation of actual username. Oracle uses a DB User account named applsyspub to which it first connects during validation of LOGIN. This user account has very restricted privileges and has access to below objects (primarily for authentication purposes):-
  • FND_APPLICATION

  • FND_UNSUCCESSFUL_LOGINS
  • FND_SESSIONS
  • FND_PRODUCT_INSTALLATIONS
  • FND_PRODUCT_GROUPS
  • FND_MESSAGES
  • FND_LANGUAGES_TL
  • FND_APPLICATION_TL
  • FND_APPLICATION_VL
  • FND_LANGUAGES_VL
  • FND_SIGNONFND_PUB_MESSAGE
  • FND_WEBFILEPUB
  • FND_DISCONNECTED
  • FND_MESSAGE
  • FND_SECURITY_PKG
  • FND_LOOKUPS

  1. All the pl/sql packages will be created in APPS Schema

  2. All the views will be created in APPS Schema
  3. For each table in individual schema, there will exist one synonym in APPS schema
  4. Tables are not created in APPS schema, every implementation has at least 1 custom schema, where custom tables are created.
  5. For each custom table created by you, you will need to create a Synonym in APPS schema

Custom tables are generally required in Oracle ERP because:
1. You wish to create a custom screens ( your own screen to capture some info) for a functionality that is not delivered by Oracle.
2. Pre-Interface tables
3. Temp processing
4. Staging of data for third party extract interfaces

To create a new table named, the steps are
Step 1. Create table in custom schema .
Step2. Grant all on schema.table_name to apps
Step 3. connect to apps/apps, and
Create or replace synonym for schema.table_name

Oracle Apps Deployment
  • Any executable that has intense database operations is stored at database tier e.g. oracle reports, sql files, sql*loader.

  • Any executable that has intense UI operations is deployed at forms tier. Examples are Oracle Forms fmx files, jsp files, pll/plx etc.
  • A form that has intense database processing, must handle most of the database processing within pl/sql packages. The api’s that you build in pl/sql must have well defined parameters.
  • Multiple mid-tiers distributes the user load. The user requests are first sent to a load balancer switch, this switch the decides which middle tier to use.
  • You will need to deploy your forms file to each middle tier machine (unles shared APPL_TOP) has been implemented.
  • FMB files delivered by oracle are picked from $AU_TOP/forms/us.
  • All of the pl/sql packages are installed in apps schema.This includes your custom packages and also oracle delivered packages.
  • The forms are attached to form functions and it is the form function that is attached to an application
  • To generate CUSTOM.pll: cd $AU_TOP/resourcef60gen module=$AU_TOP/resource/CUSTOM.pll userid=apps/apps output_file=./CUSTOM.plx module_type=LIBRARY

Optional environments:-
  • CRP environment: Conference room pilot environment is where usually implementation team gets buying to their product offering from user community, during implementation. This environment is usually used for sign off during new implementations.

  • Patching environment: This is where all new Oracle Patches are sanity tested.
  • Support environment: This environment is exclusive to support staff. This environment is usually the most frequently cloned environment in Oracle Apps site that has gone live. Frequent cloning helps the Oracle Applications support staff to reproduce production issues
  • Migration Environment: This is where repeated data migration can take place before migration code gets frozen and ready for UAT.

Overview of Standard Request Submission

Standard Request Submission is a feature that works with concurrent processing to provide a common interface for running your Oracle Applications reports and programs.
Standard Request Submission provides you with a set of windows for running reports and programs and a set of windows for creating groups of reports and programs to run together. These windows give you control over the submission and output of your reports and programs.

Attention: Some Oracle Applications products provide, in addition to the Standard Request Submission windows, product-specific windows to submit certain reports and programs. Such a window automatically runs a report or a program as a concurrent process when you choose a specific button or save your work in the form.

The Post Journals window in the Oracle General Ledger application is an example of a window that submits a concurrent program to post journal entries when you choose the Post button. You should refer to the user’s guide for your Oracle Applications product to learn if your product uses any product-specific windows to submit reports or programs.

  • Provides standard interface for running and monitoring reports.
  • Single form to submit any request, concurrent program. Another form to see report’s progress and to review report online.
  • Submit Request form: easy-to-use interface.
  • Automatic Resubmission.
  • Request Sets: define sets of reports, Submit an entire set at same time.
  • Request Set options: Run order, printer, no. of copies etc.
  • Request Set Log File:Single log file containing the completion status of all reports in set.
  • Viewing Requests: Monitor report’s progress using View Request form.
  • Child Request: or a sub-request submitted by any other concurrent request(Parent Request)
  • Parameter: A value you specify when you run a request.

* A request set is parent request and all reports in set are child requests
Value Set: A set of values against which AOL validates values, the end user enters when running a concurrent program.
Controlling Access to Reports:

  • Create related group of reports and request sets.
  • Define responsibility and assign a report security group to that responsibility.

Request Sets:

  • A collection of reports/programs that are grouped together. Allow to submit reports or programs in a request set all at once using a single transaction.
  • Request set can be defined to submit requests depending on the completion status of previously submitted requests in the set.

Stage:

  • Component of a request set used to group requests within a set. All requests in a stage are executed in parallel. Request set executes one stage at a time., following links from stage to stage.
  • Links that are followed depend on the completion status of the individual stages. A stage completes when all the requests contained in the stage have completed.
  • PL/SQL functions calculate the completion status of a stage
  • Three status of a stage:
  1. Success
  2. Warning
  3. Error

Stage Evaluation function:

  • Provided by AOL, computes the stage completion status from the completion statuses of the specified requests in set.
  • Function returns a
  1. Success: If all requests completed with a status of “Success”.
  2. Warning: If one or more requests in set completed with warning and no request completed with error.
  3. Error: If any request in set completed with error.
