Troubleshooting Strategy and Processes that Execute Enormous data sets in Demantra

Hello Demantra Customers!   There is a new white paper that discusses large data set loading.

See MOS Note 1634925.1

Recently we have encountered a few scenarios where customers tried to process huge amounts of data within a Demantra process.
Examples:

  • Customer wanted to load over 50M records via EP_LOAD process on weekly bases.
  • Customer wanted to process millions of rows via BLE process on daily bases.
  • Customer wanted to load via integration interface 40M rows on weekly bases.


In all of the above the customer complained about the system inability to process the amount of data, either being too slow or it simply could not be completed at all meaning the process erred out.
In all of the above examples an escalated defect was logged, and development worked troubleshooting the problem.

An additional common theme between all the above examples and many more is that there was no real need to have a product fix although performance improvement opportunities may have been identified, they were not the final solution that addressed the problem.
What helped was understanding that there is no real need to process all the data and recognizing the data that really needed to be loaded.  The data could have been loaded in a more efficient way using some best practices and creative thinking.

The scope of this document is to provide some guidance how to troubleshoot such customer situations.
The document will focus on three main areas:

  • Learning and understanding the business needs
  • Understanding the actual data that needs to be loaded, understand the gap between this number and the number of rows that the customer actually tries to load.
  • Provide some best practices that can help the customer work with the data efficiently.


This document will not deal with the initial Data load processes although some of the best practices can be adopted for such situations as well.
We will illustrate the concepts in this document using three real life examples of service requests and/or defects that were logged on behalf of the customer.

REPLACEMENT OF APS SIZER with VALUE CHAIN PLANNING REFERENCE SIZING TOOL (RAS)

The Value Chain Planning - Reference Sizing Tool (RAS) provides Capacity & Deployment planning for the Value Chain Planning customers.  It is part of your early sales cycle to qualify, scope and budget your opportunity.  It provides a System Sizing for Oracle Software on Oracle Hardware as well as competitor hardware.  The tool provides guidelines on what the customer should consider for deployment of Value Chain Planning, as well as a comparison to Oracle hardware.  The tool will advise on suitable hardware and software configuration based on the user responses to a series of questions related to the customer requirements.  The more accurate the input, the more accurate the results will be.

The output reports can be used as a sizing estimate.  Most typical scenario is for a System Integrator (SI) to provide the inputs based on the customer’s implementation strategy.  

With a unified methodology across all Oracle software and hardware, RAS supports greenfield as well as consolidation or hardware refresh opportunities. The extremely quick turnover and what-if scenarios enables you to help guide you through the sales-implementation cycle.  Results displayed are estimates based on benchmark results produced by Oracle and best practices gained over the years from customer support and feedback.

Demantra 12.2.2 Upgrade WARNING

We have a MOS note for upgrade problems when upgrading to 12.2.2.

Oracle Demantra Platform Upgrade to 12.2.2 Known Issues Worksheet Performance Calendar Excel ORA-0179 ORA-06512 ORA-31003 java.lang.NullPointerException (Doc ID 1602288.1)

- DO NOT upgrade from 7.3.x, 12.2.0 or 12.2.1 to 12.2.2.

- DO NOT run the 12.2.2 upgrade twice.

Currently there is a bug in the 12.2.2 upgrade that can cause serious corruption in those cases.  Customers should instead upgrade from 7.3.x, 12.2.0 or 12.2.1 to 12.2.3.
I do not know when/if we will fix this issue.  Right now 12.2.2 cannot be downloaded.

Note:  that there is already a section in that MOS note detailing a work-around for a different problem when upgrading from 12.2.1 to 12.2.2.  The existence of that work-around might imply that it is ok to do the upgrade -- but it is NOT ok to do that upgrade

Demantra 12.2.3 Is Now Available!

Greetings!   Demantra 12.2.3 is now available via ARU 17048199, Bug 17921238

1. This release includes both a platform and application upgrade option. Please note the application upgrade installer option is available only to customers who have implemented the *standard* pre-configured applications (available from Demantra 7.1.1 onwards). You should choose the 'Platform Upgrade Only' option only if your implementation is highly customized. A platform-only upgrade will preserve custom configurations and enable new platform functionality. It will not introduce new application objects. Also note Demantra 7.2.1 customers should contact support prior to running an application upgrade, to get latest patch details for that release.

Please note the upgrade process may identify certain objects which have changed between your existing Demantra version (Demantra 7.1.1 or 7.2.0.2, for example) and the current release. This may be due to Oracle extensions in the latest release and/or due to customer extensions in their implementation. In a default upgrade mode, the current versions of these objects will be preserved during the upgrade process and, where there are conflicting definitions with the new Oracle version, we will create duplicate objects with a version suffix.

For example, if you extended the configuration of the workflow 'EBS Price List Download', the upgrade process will maintain this and introduce the Oracle standard workflow as 'EBS Price List Download_730'. In some cases, the original object may be suffixed with its version (for example, 'EBS Full Download_711'and the latest configuration will be 'EBS Full Download'). You will identify the latest version by either a suffix of the latest version, or by a sibling item with an earlier version stamp. You may then review the two and merge as appropriate. In the case of duplicate objects, it is recommended to use the latest version, preferably after removing the ‘_730’ suffix and merging any of your customizations into the latest version.

For Predictive Trade Planning customers, you will note that Promotion Type is no longer a level but instead a series, after application upgrade. This enables promotions to have multiple tactics per promotion, typically for different items or locations being promoted. While promotion type can now vary across different items, locations, it should not vary below the Lowest Promotional Level defined in the forecast tree.

If you are uncertain as to which upgrade option to choose, please contact support for guidance.


2.  If you already installed 12.2.1 or 12.2.2 (using the application upgrade or new installation), please do not choose the "platform and application upgrade" option. Instead, choose to perform only a "platform upgrade."

3.  If you are upgrading from a release that did not support Service Parts Forecasting (SPF) functionality and you want to use SPF, you MUST select the "Platform and Application Upgrade" option when running the Demantra Installer. SPF functionality will not work when upgrading from a pre-SPF supported release to 7.3.1 or later after a PLATFORM-only upgrade.

4. Customers who are on 7.3.1.5 or later who are using In-Memory Consumption Driven Planning (CDP) cannot upgrade to 12.2.3, as 12.2.3 does not support those enhancements.


A future release of the 12.2.x branch will include the 7.3.1.5 CDP enhancements, and upgrading from 7.3.1.5 or later will be supported at that time. Please contact Oracle Support for additional information.



For known issues and work arounds, see MOS note Demantra 12.2.3 Upgrade / Install Known Issues and Workarounds (Doc ID 1608474.1)

Demantra Integration Interface Modifications via the Database

How does one do modifications to the Integration Interface from the database?  Is there a java class that can be used for this?

Looking to avoid logging into the Business Modeller to perform these modifications?

1) The interface tables in the database are a set of tables starting with "Transfer_", while transfer_query is the main one. There are separate tables for series, levels, filter etc.

2) I do not believe there is a Java class for this.

3) A Java servelet is triggered when an Integration interface is modified through business modeler so that an application server bounce is not required. This servelet is specific to integration interfaces only.

4) Any update to the "transfer_xxx" table(s) would need application server bounce.

As per my knowledge, logging into Business modeler and modifying is the recommended option, mainly where multiple tables in the database get updated.

Upgrading to 12.2.2? Do you want extra speed? Use a logon trigger for parallelism

When upgrading your Demantra application from an older version directly to 12.2.2, you can minimize the upgrade time.  You can force parallelism using a Logon trigger on the server.

   Creation of new Indexes on sales data can take long time.

   As part of the upgrade there is a script building a new set of indexes, one per engine profile, on each profile quantity_form expression.

   The creation of the index can take a long time on big data tables.

    - Remember to disable or drop that trigger when the upgrade has completed.

   The following trigger was created as SYS database user and tested successfully by creating DEMANTRA database user and logging in with it:

 CREATE OR REPLACE TRIGGER force_parallel_ddl_trg

AFTER LOGON ON database

BEGIN

  IF (USER='DEMANTRA') THEN

    EXECUTE IMMEDIATE 'ALTER SESSION FORCE PARALLEL DDL';

  END IF;

END force_parallel_ddl_trg;

/

 Make sure to:

  1. Modify DEMANTRA to be the database schema name.
  2. drop it after it is not needed anymore using the foillowing:

 DROP TRIGGER force_parallel_ddl_trg;
