Best practices for administering Oracle Big Data Appliance

-        Best practices as part of administration of Oracle Big Data Infrastructure
-        How do we lock down max space usage per project
Eg: Project team A can have a max limit of 10 TB space allocated
-        Restricting roles, access ( Read, Write), place holder for common shared artifacts
-        Template/procedure for code migration across dev,qa and prod environments etc

Your data is bigger than I run, but what I have done in the past is to restrict their accounts to a separate datafile and limit its size to the max that I want for them to use: create objects restricted to accommodate the location.

Best practice for integrating oracle atg with external web service

Hi All
What is the best practice for integrating oracle atg with external web service? Is it using integration repository or calling the web service directly from the java class using a WS client?
With Thanks & Regards
Abhishek

Using Integration Repository might cause performance overhead based on the operation you are doing, I have never used Integration Repository for 3rd Party integration therefore I am not able to make any comment on this.
Calling directly as a Java Client is an easy approach and you can use ATG component framework to support that by making the endpoint, security credentials etc as configurable properties.

Best practice for install oracle 11g r2 on Windows Server 2008 r2

Dear all,
May I know what is the best practice for install oracle 11g r2 on windows server 2008 r2. Should I create a special account for windows for the oracle database installation? What permission should I grant to the folders where Oracle installed and the database related files located (datafiles, controlfiles, etc.)
Just grant Full for Administrators and System and remove permissions for all others accounts?
Also how should I configure windows firewall to allow client connect to the database.
Thanks for your help.

Best practice for Plan and actual data

Hello, what is the best practice for Plan and actual data? should they both be in the same app or different?
Thanks.

Hi Zack,
It will be easier for you to maintain the data in a single application. Every application needs to have the category dimension, mandatorily. So, you can use this dimension to maintain the actual and plan data.
Hope this helps.

Best Practices for Accessing the Configuration data Modelled as XML File in

Hi,
I refer the couple of blof posts/Forum threads on How to model and access the Configuration data as XML inside OSB.
One of the easiest and way is to
Re: OSB: What is best practice for reading configuration information
Another could be
Uploading XML data as .xq file (Creating .xq file copy paste all the Configuration as XML )
I need expert answers for following.
1] I have .xsd file which is representing the Configuration data. Structure of XSD is
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue</Config>
<FrameworkConfig>
2] As my project will move from one env to another the property-value will change according to the Environment...
For Dev:
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Dev</Config>
<FrameworkConfig>
For Stage :
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Stage</Config>
<FrameworkConfig>
3] Let say I create the following Folder structure to store the Configuration file specific for dev/stage/prod instance
OSB Project Folder
|
|---Dev
|
|--Dev_Config_file.xml
|
|---Stage
|
|--Stahe_Config_file.xml
|
|---Prod
|
|-Prod_Config_file.xml
4] I need a way to load these property file as xml element/variable inside OSb message flow.?? I can't use XPath function fn:doc("URL") coz I don't know exact path of XMl on deployed server.
5] Also I need to lookup/model the value which will specify the current server type(Dev/Stage/prod) on which OSB MF is running. Let say any construct which will act as a Global configuration and can be acccessible inside the OSb message flow. If I get the vaalue for the Global variable as Dev means I will load the xml config file under the Dev Directory @runtime containing key value pair for Dev environment.
6] This Re: OSB: What is best practice for reading configuration information
suggest the designing of the web application which will serve the xml file over the http protocol and getting the contents into variable (which in turn can be used in OSB message flow). Can we address this problem without creating the extra Project and adding the Dependencies? I read configuration file approach too..but the sample configuration file doesn't show entry of .xml file as resources
Hope I am clear...I really appreciate your comments and suggestion..

If you can enforce some sort of naming convention for the transport endpoint for this proxy service across the environments, where the environment name is part of the endpoint you may able to retrieve it from $inbound in the message pipeline.
eg. http://osb_host/service/prod/service1 ==> Prod and http://osb_host/service/prod/service2 ==> stage , then i think $inbound/ctx:transport/ctx:uri can give you /service/prod/service1 or /service/stage/service1 and applying appropriate xpath functions you will be able to extract the environment name.
Chk this link for details on $inbound/ctx:transport : http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1080822

In the Begining it's Flat Files - Best Practice for Getting Flat File Data

I probably should have posed this question here before I delved into writing Java to get data for reports, but better late than never.
Our ERP is written in COBOL. We have a third party ODBC which allows us to access data using a version of SQL. I have several Java sources compiled in my database that access the data and return something relevant. The Java sources are written in a procedural style rather than taking advantage of object oriented programming with attributes and methods.
Now that I am becoming more comfortable with the Java language, I would greatly appreciate any feedback as to best practices for incorporating Java into my database.
My guess is that it would be helpful to model the ERP "tables" with Java classes that would have attributes, which correspond to the fields, and methods to return the attributes in an appropriate way. Does that sound reasonable? If so, is there a way to automate the task of modeling the tables? If not reasonable, what would you recommend?
Thanks,
Gregory

OO is a choice not a mandate. Using Java in a procedural way is certainly not ideal but given that it is existing code I would look more into whether is well written procedural code rather than looking at the lack of OO.

You then implement using whatever means seem expedient in terms of other business constraints to closely model that data model.
It is often the case that there is a strong correlation between data models and tables but certainly in my experience it is rare when there are not other needs driven by the data model (such as how foreign keys and link tables are implemented and used.)

Best practice for including additional DLLs/data files with plug-in

Hi,
Let's say I'm writing a plug-in which calls code in additional DLLs, and I want to ship these DLLs as part of the plug-in. I'd like to know what is considered "best practice" in terms of whether this is ok (assuming of course that the un-installer is set up to remove them correctly), and if so, where is the best place to put the DLLs.
Is it considered ok at all to ship additional DLLs, or should I try and statically link everything?
If it's ok to ship additional DLLs, should I install them in the same folder as the plug-in DLL (e.g. the .8BF or whatever), in a subfolder of the plug-in folder or somewhere else?
(I have the same question about shipping additional files too, such as data or resource files.)
Thanks

Best Practices for user ORACLE

Hello,
I have few linux servers with user ORACLE.
All the DBAs in the team connecting and working on the servers as ORACLE user and they dont have sperate account.
I create for each DBA its own account and would like them to use it.
The problem is that i dont want to lock the ORACLE account since i need it for installation/upgrade and etc , but yet i dont what
the DBA Team to connect and work with the ORACLE user.
What are the Best Practice for souch case ?
Thanks

To install databases you don't need acces to Oracle.
Also installing 'few databases every month' is fundamentally wrong as your server will run out of resources, and Oracle can host multiple schemas in one database.
"One reason for example is that we have many shell scripts that user ORACLE is the owner of them and only user ORACLE have a privilege to execute them."
Database control in 10g and higher makes 'scripts' obsolete. Also as long as you don't provide w access to the dba group there is nothing wrong in providing x access.
You now have a hybrid situation: they are allowed interactively to screw 'your' databases, yet they aren't allowed to run 'your' script.
Your security 'model' is in urgent need of revision!

Best practice for phone number column data type

Hi,
I hope I have posted this in the right forum, if not just notify me and i will remove it to the correct area.
What would be considered best practice for storing a phone number.
Number of Varchar2.
Ben

Well I was thinking that Number would have the following disadvantages,
1. Users entering phone numbers into a form may be tempted to pre format with spaces, thereby throwing up an error.
2. Mobile phone numbers may have leading zeros
3. Calculations are not carried out on phone numbers.
I was leaning towards a varchar2 type.

Best practice for having separate clone data for development purposes?

Hi
I am on a hosted Apex environment
I have a workspace containing two instances/ copies of the application: DEV and PROD
I would like to be able to develop functionality and data in/ with the DEV instance and then insert it into DEV.
I gather that I can insert pages from DEV to PROD via Create -> New page as copy -> Page in another application
But I don't know how I can mimic this process with database objects, eg. if I want to create a new table or manipulate the data in an existing table in a DEV environment before implementing in a PROD environment.
Ideally this would be done in such a way that minimises changing table names etc when elevating pages from DEV to PROD.
Would it be possible to create a clone schema that could contain the same tables (with the same names) as PROD?
Any tips, best practices appreciated :)
Thanks

Hi,
ideally you should have a little more separation between your dev and prod environments. At the minimum you should have separate workspaces each addressing separate schemas. Apex can be a little difficult if you want to move individual Apex application objects, such as pages, between applications (a much requested improvement), but this can be overcome by exporting and importing the whole application. You should also have some form of version control/backup of export files.
As far as database objects go, tables etc, if you have tns access to your hosted environment, then you can use SQL Developer to develop, maintain and synchronize between your development and production schemas and objects in the different environments should have identical names. If you don't have that access, then you can use the Apex SQL Workshop features, but these are a little more cumbersome than a tool like SQL Developer. Once again, scripts for creating and upgrading your database schemas should be kept under some sort of version control.
All of this is supposing your hosting solution allows more than one workspace and schema, if not you may have to incur the cost of a second environment. One other option would be to do your development locally in an instance of Oracle XE, ensuring you don't have any version conflicts between the different database object features and the Apex version.
I hope this helps.

Andre

Best practices for an oracle application upgrade

Hello,
We have an enterprise application deployed on Oracle Weblogic and connecting to an Oracle database (11g).
The archive is versioned and we are using Weblogic's feature to upgrade to new versions and retire old versions.
In a case of emergency when we need to rollback an upgrade, the job is really easy on Weblogic but not the same on Oracle DB.
For most of our releases, the release package is an ear plus some database scripts.
Releases are deployed with minimum downtime, so while we are releasing our clients are still writing to the DB.
In case of a rollback is needed, we need to make sure the changes we made to the DB structure (Views, SP, Tables...) are reverted but data inserted by clients stayed intact.
Correct me if I am wrong, but Flashback and RMAN TSPITR are not the good options here.
What other people usually do in similar cases? What are best practices and deployment plans for our case?
Guides and direction are welcomed.
Thanks!

Hi Magnus
I guess you have to install again to ensure no problems. BP installation also involves ensuring correct SP levels (cannot be higher) for all software components.

Best Practice for Significant Amounts of Data

This is basically a best-practice/concept question and it spans both Xcelsius & Excel functions:
I am working on a dashboard for the US Military to report on some basic financial transactions that happen on bases around the globe. These transactions fall into four categories, so my aggregation is as follows:
Year,Month,Country,Base,Category (data is Transaction Count and Total Amount)
This is a rather high level of aggregation, and it takes about 20 million transactions and aggregates them into about 6000 rows of data for a two year period.
I would like to allow the users to select a Category and a country and see a chart which summarizes transactions for that country ( X-axis for Month, Y-axis Transaction Count or Amount ). I would like each series on this chart to represent a Base.
My problem is that 6000 rows still appears to be too many rows for an Xcelsius dashboard to handle. I have followed the Concatenated Key approach and used SUMIF to populate a matrix with the data for use in the Chart. This matrix would have Bases for row headings (only those within the selected country) and the Column Headings would be Month. The data would be COUNT. (I also need the same matrix with Dollar Amounts as the data).
In Excel this matrix works fine and seems to be very fast. The problem is with Xcelsius. I have imported the Spreadsheet, but have NOT even created the chart yet and Xcelsius is CHOKING (and crashing). I changed Max Rows to 7000 to accommodate the data. I placed a simple combo box and a grid on the Canvas u2013 BUT NO CHART yet u2013 and the dashboard takes forever to generate and is REALLY slow to react to a simple change in the Combo Box.
So, I guess this brings up a few questions:
1)     Am I doing something wrong and did I miss something that would prevent this problem?
2)     If this is standard Xcelsius behavior, what are the Best Practices to solve the problem?
a.     Do I have to create 50 different Data Ranges in order to improve performance (i.e. Each Country-Category would have a separate range)?
b.     Would it even work if it had that many data ranges in it?
c.     Do you aggregate it as a crosstab (Months as Column headings) and insert that crosstabbed data into Excel.
d.     Other ideas that Iu2019m missing?
FYI: These dashboards will be exported to PDF and distributed. They will not be connected to a server or data source.
Any thoughts or guidance would be appreciated.
Thanks,
David

Best Practice for thinning Oracle Forms

We are considering upgrading from 10g (10.1.2.3) to (probably) 11g forms initially whist long term migrating to ADF.
Our system is 15 years old and has many issues that go along with a system this old i.e. database keys/indexes missing, forms with lots of code etc.
We have very few resources so thought the best way to go about this would be to thin out all our Oracle forms in 10g prior to upgrade (as this is mainly just a recompile in 11g) but was looking at if there were any best practices as to what level this should be done.
For example we heavily use PLLs. Should the majority of this code be moved into packages or are PLLs ok to use. I take it the majority of program units should be moved to db.
How thin should we aim to make the form. i.e if we are using post queries for something as simple as select customername into :nondbitem from customer where customerid =:customerid. Should we be making this a function in the db and reusing the code in the necessary places?
Just wondering what people would deam best practice before we start.
Thanks

Thanks for all your input.
Although the current database design is not correct we are going to correct the existng database rather than rewriting it.
So were hoping to correct this also!
But what im doing now to get rid some of this post queries for nondbnames is im creating a view of all information i need to display on one pertaining record.
Then i used this view like block basic procedure like relationship to the transactional block.So if you make queries or insert (need to run query the block view) it will give all the necessary record display"
{CODE}
This sounds sensible but we havs hundreds of tables with lots of columns. How are you managing the views/deciding how manytables/columns to include on the forms?
