Best practices for defining Environment Variables/User Accounts in Linux

Hello,
After reading throught the Quick Install guide for 10gR2 on x86_64 Linux, I see that it is not recommended to define ANY variables in .bash_profile.
I'm hoping to get a Best practices approach for defining environment variables - right now we use the oracle linux account for administration including sql*plus. So, where should the myriad variables be defined? Is it important enough to create a user account in linux to support best practices?
What variables, exactly, should be defined? It seems that LD_LIBRARY_PATH is no longer being used?
Thanks in advance
Doug

Something that I've done for years on unix/linux boxes is to create a seperate environment variable setup file for each instance on the box. This would include things like ORACLE_HOME, ORACLE_SID, etc. Then I would create an alias in my .bash_profile that would execute this script. As an example, I would create a orcl.env file that would hold all of the environment variables for this instance. Then in my .bash_profile I would create a line like the following:
alias orcl=". $HOME/orcl.env"
Then from anywhere you could type orcl and you would set your environment to connect to that database.
Also, if you are using 10g, something else that is really nice if you are using sqlplus, and you connect to different databases without starting a new sqlplus session is to set a parameter in your $ORACLE_HOME/sqlplus/admin/glogin.sql file:
set sqlprompt "_user 'at' _connect_identifier >"
This will automatically change your command prompt to look like this:
RALPH at ORCL >
if you connect as GEORGE, your prompt will immediately change to :
GEORGE at ORCL >
This way you can always know who and where you are connected to.
Good luck!

Best Practices for Defining NDS Java Projects...

We are doing a Proof of Concept on using NDS to develop non-SAP Java applications. We are attempting to determine if we can replace our current Java development tools with NDS/WAS.
We are struggling with SAP's terminology and "plumbing" for setting up/defining Java projects. For example, what is and when do you define Tracks, Software Components, Development Components, etc. All of these terms are totally foreign to us and do not relate to our current Java environment (at least not that we can see). We are also struggling with how the DTR and activities tie in to those components.
If any one has defined best practices for setting up Java projects or has struggled with and overcome these same issues, please provide us with some guidance. This is a very frustrating and time-consuming issue for us.
Thank you!!

Hi Peggy,
In Component Model we divide software projects into small components.Components can use other components in well defined manner.
A development object is a part of a component that can be changed or developed in some way; it provides the component with a certain part of its functionality. A development object may be a Java class, a Web Dynpro view, a table definition, a JSP page, and so on. Development objects are always stored as sources in a repository.
A development component can be defined as a frame shared by a number of objects, which are part of the software.
Software components combine components (DCs) to larger units for delivery and deployment.
A track comprises configurations and runtime systems required for developing software component versions.It ensures stable states of deliverables used by subsequent tracks.
The Design Time Repository is for versioning source code management. Distributed development of software in teams. Transport and replication of sources.
You can also find lot of support in SDN for the above concepts with tutorials.

Best Practice for Production environment

Hello everyone,
can someone share the best practice for a production environment? or is there a SAP standard best practice to follow in a Production landscape?
i understand there are Best practices available for Implementation , Migration and upgrade. But, i was unable to find one for productive landscape
thanks.

Hi Siva,
What best practise are you looking for ? If you can be specific on your question we could provide appropriate response.
From my basis experience some of the best practices.
1) Productive landscape should have high availability to business. For this you may setup DR or HA or both.
2) It should have backup configured for which restore has been already tested
3) It should have all the monitoring setup viz application, OS and DB
4) Productive client should not be modifiable
5) Users in Production landscape should have appropriate authorization based on SOD. There should not be any SOD conflicts
6) Transport to Production should be highly controlled. Any transport to Production should be moved only with appropriate Change Board approvals.
7) Relevant Database and OS security parameters should be tested before golive and enabled
8) Pre-Golive , Post Golive should have been performed on Production system
9) EWA should be configured atleast for Production system
10) Production system availability using DR should have been tested
Hope this helps.

Best Practice for Multiple iTunes and One Account?

My wife and I share our account for our iPhone Applications and Songs in iTunes.
Can someone point me to a topic that covers a best practice for multiple iTunes syncing?
I travel a lot and keep my iPhone synced to my Macbook Pro while she uses the workstation at home to sync to. We keep the addresses and contacts and calendars synced through MobileMe, however, I'm trying to find the best way of pushing applications and songs I've bought over to the other PC so they're still around while I'm traveling for her to sync with.
Thoughts?

Hi Steve,
Might be trying for solution for a long time, If i understood your question clear let me clarify you few points.
You are trying to access the bex query which is designed with the exit's in the background based on the logic and trying to call the entire dimensions and key-figures in a single connection. Then you are trying to map those data in the charts.
Steve, try to make more connections based upon the logic and split them. use the same query but split them by sales per customer group, sales per day, sales per week by making three different connections and try. You can merge the prompts from all connections.
Hope this Helps!!!
Sorry if i misunderstood your question.

Best Practice for setting bind variable when application loads

I am using JDeveloper 11.1.2.3.
When my application loads, the first unbounded page has a table populated by a named query.
I would like to set the parameter used by the named query when the page loads, to populate the initial data that is displayed.
What is the best practice for a solution to this issue?

Best practices for setting environment based static variables?

I have a set of static string variables that hold the url location of modules in a project. These locations change depending on whether I'm building for development, staging or production.
What's the best way to set static variables in this way?

I don't know if this is best practice, but here's the solution I've come up with.
The root domain is accessible within the swf via a node on a loaded xml file. So I created a simple method that sets a url variable based on that domain node.
The domain-based url variable is then used within the static string variables that define the location of the modules.
Simplified like so:
var domain:String = xml.node.value;
static var bucketLocation:String = getLocation()
static var moduleLocation:String = bucketLocation + "modulename.swf";
function getLocation():String
     var loc:String
     switch (domain) {
          case stagingUrl:
              loc = "pathToAmazonStagingBucket";
               break;
          case productionUrl:
               loc = "pathToAmazonProductionBucket";
               break;

Best practice for select access to users

Not sure if this is the correct forum to post, if not then let me know where should I post.
From my understanding this is the best forum to ask this questions.
Are you aware of any "Best Practice Document" to grant select accesses to users on databases. These users are developers which select data out of database for the investigation and application bug fix.
From time to time user want more and more access to different tables so that they can do investigation properly.
Let me know if there exists a best practice document around this space.
Asked in this forum as this is related to PL/SQL access.

Welcome to the forum!
Whenever you post provide your 4 digit Oracle version.

There are many best practices documents about various aspects of security for Oracle DBs but none are specific to developers doing invenstigation.
Here is the main page for Oracles' OPAC white papers about security.
http://www.oracletechnetwork-ap.com/topics/201207-Security/resources_whitepaper.cfm
Take a look at the ones on 'Oracle Identity Management' and on 'Developers and Identity Services'.
http://www.dbspecialists.com/files/presentations/implementing_oracle_11g_enterprise_user_security.pdf
This paper by Database Specialists shows how to use Oracle Identity Management to limit access to users such as developers through the use of roles. It shows some examples of users using their own account but having limited privileges based on the role they are given.
http://www.dbspecialists.com/files/presentations/implementing_oracle_11g_enterprise_user_security.pdf
And this Oracle White Paper, 'Oracle Database Security Checklist', is a more basic security doc that discusses the entire range of security issues that should be considered for an Oracle Database.
http://www.oracle.com/technetwork/database/security/twp-security-checklist-database-1-132870.pdf
You don't mention what environment (PROD/QA/TEST/DEV) you are even talking about or whether the access is to deal with emergency issues or general reproduction and fixing of bugs.
Many sites create special READONLY roles, eg. READ_ONLY_APP1, and then grant privileges to those roles for tables/objects that application uses. Then that role can be granted to users that need privileges for that application and can be revoked when they no longer need it.
Some sites prefer creating special READONLY users that have those read only roles. If a user needs access the DBA changes the password and provides the account info to the user. When the user has completed their duties the DBA resets the password to something no one else knows.
Those special users have auditing on them and the user using them is responsible for all activity recorded in the logs during the time the user has access to that account.
In general you grant the minimum privileges needed and revoke them when they are no longer needed; generally through the use of roles.
>
Asked in this forum as this is related to PL/SQL access.
>
Please explain that. Your question was about 'access to different tables'. How does PL/SQL access fit into that?
The important reason for the difference is that access is easily controlled thru the use of roles but in named PL/SQL blocks roles are disabled. So those special roles and accounts mentioned above are well-suited to allowing developers to query data but are not well-suited if the user needs to execute PL/SQL code belonging to another schema (the app schema).

Best Practice for MUD Environment

Hi Guys,
I initially thought of using Merge Repository as an option to MUD Environment.
But I found that while merging repositories, You have to either accept changes from Modified or Current Repository.
What if I have 2 developers working parallel in a single Presentation Folder?
Then I though Project based MUD Implementation will be the only option but in that Developers will have power to keep or remove changes from other developer.
Now I am confused how I can get multiple users develop single RPD.
Please let me know what's the best practice used?
Thanks
Saurabh

Below some explanations. Follow the links, if you want more information. Personnaly, I prefer to set up a MUD environment.
Software Configuration Management
By default, the Oracle BI repository development environment is not set up for multiple users. However, online editing makes it possible for multiple developers to work simultaneously, though this may not be an efficient methodology, and can result in conflicts, because developers can potentially overwrite each other's work.
To develop a repository in a concurrent version environment, you have several choices :
* first of all, you can send the repository to the developper, keep a copy, retrieve it after modification and perform an [Merge Repository|http://gerardnico.com/wiki/dat/obiee/obiee_repository_merge|Merge Repository]
* second, you can set up a [multiuser environment (MUD)|http://gerardnico.com/wiki/dat/analytic/obiee/multiuser_environment] which use the notion of Projects to split the work area. It would permit developers to modify a repository simultaneously and then check in changes.
The import option which permit to import a subset of a repository to an other repository, work but is deprecated.

Best Practice for legally required Chart of Account

Dear all,
our client has a global defined chart of account. Now they are going to implement the SAP template in France, Belgium and Russia. These countries have legally required chart of accounts. What is best practice to fullfill these requirements in SAP.
1) Do I use the alternative account number?
2) Isn't this field on the central level of the account master data record? How do I manage to realize the different number for Russia and for France at the same time?
Thank you very much for your help.
Best regards Timo

Hi,
the best way proofed by real life is to define new chart of accounts for the country specific accounts. Then to assign this chart of accounts as country chart of accounts in company code parameters.
Then you can use field alternative account number in company code segment of G/L accounts.
Just keep in mind that the assigment should be 1:1, i.e. one operative (global) account is assigned to one local account and one local account should be assigned to one operative account.
You can't change the alternative account number if there is balance on that account. You can just repost the balance to another account, then change alternative acccount number and then post the balance back. For some accounts its difficult to do such excercise so I use short ABAP which changes directly the field in table SKB1.
You can also define financial statement strucutre based on local chart of accounts - which is usually easier for maintennace, because you can use intervals. Just do not forget check "Alternantive accounts" in RFBILA00.

Michal

Best Practice for initialising class variables, should they be null?

class Person
private String name, address;
public String getName()
return name
public void main()
Person me = new Chris()
..........loads of code........
if(me.getName==null)
do something
else
do something else
So my question is : whats the best behaviour when declaring variables? In this case should I have initialized the Strings to the empty string?
I think i need to make a decision because I'm constantly unsure if the method should return null or empty string. So i find myself doing this occasionally :
if(person.getName()==null || person.getName().equalIgnoreCase(""))
Thanks
Chris

I believe that when you create an object it should be 100% ready for use. That means all private member variables set to a non-null, sensible value.
You shouldn't force clients to know what's safe and what's not:
public class Person
    private String name;
    private Date birthDate;
    public static void main(String [] args)
        Person p = new Person();
        System.out.println("age: " + p.getAge());
    public Person() { // do nothing; name is null }
    public String getName() { return name; }
    public void setName(String newName) { name = newName; }
    public Date getBirthDate() { return birthDate; }
    public void setBirthDate(Date newBirthDate) { birthDate = new Date(newBirthDate.getTime()); }
    public int getAge()
        int age = 0;
        // calculating age with a null birth date will be a problem.
        return age;
}You might argue that it's perfectly reasonable to expect a user to call setters to initialize an object after it's created, but I don't like that idiom. There's no guarantee that it'll be done properly.

Best practice for mutable global variables

I have read around a couple of posts regarding the topic and still haven't come to any with just the right answer for the best way to work with a variable which everybody other object needs to read and/or write? I have read about multiple ways for immutable variables but not quite sure what to do with mutable ones.
I prefer to declare them in a global.h file
extern NSString *currentUserName;
and then in the global.m file
NSString *currentUserName = @"none";
in this scenario a user can login or logout at any time so every object throughtout the program should be able to change the username.
Any inputs as to why thise shouldn't be done like this? Any other ideas?

Is this a multithreaded application? If it is, then you will need to use some sort of locking on it. I prefer the "@synchronized" directive.
The proper way to handle something like this is with a singleton. Ideally, that singleton should be a UserNameController. It, and only it, should be able to update the user name. Anyone else has read access only.

Best Practice for managing Groups and Users

We want to create a Corporate Portal for the Department and it's Organizations. We want to have one Portal Public page as the main entry for all our users. When a user login, he will be re-direct to is Organization Portal page.
I need to find a good document, a case study if possible, on how to define my Groups in OID to achieve this. I need a document that explain how to setup and manage Groups for a Corporate Portal.
Thank you!

Hi!
The Portal Admin Guide gives a good overview about the groups administration.
I don't know about case studies that address your problem.
When you have different home pages for different groups you can administer this with the Portal Group Profile portlet in the admin section of Portal.

Best practice for low bandwidth end-users

Hey guys,
I'm new to CS and am about halfway through my planning stages for a web app.
My end users will be predominantly on 256k-512k connections (yeh I know it sucks, but this is regional/rural Australia) and a fairly large proportion of those are going to be on satellite which is incredibly latent.
Does anyone have some tips on keeping it lean and mean regarding coding or have any experience's they'd mind sharing?
Cheers

Best Practices for zVM/SLES10/zDB2 environment for dialog instances.

Hi, I am a zSeries system programmer who has just completed an IBM led Proof of Concept which demonstrated the viability of running SAP instances on SUSE SLES10 Linux booted in zVM guests and accessing zDB2 data via hipersockets. Before we build a Linux infrastructure using the 62 IFLs we just procured, we are wondering if any best practices for this environment have been developed as an OSS note or something else by SAP.    Below you will find an email which was sent and responded to by IBM and Novell on these topics...
"As you may know, Home Depot has embarked on an IBM led proof of concept using SUSE SLES10 running in zVM guests on IBM zSeries hardware to host SAP server instances. The Home Depot IT organization is currently in the midst of a large scale push to modernize our merchandising and people systems on SAP platforms. The zVM/SUSE/SAP POC is part of that effort, as is a parallel POC of an Intel Blade/Red Hat/SAP platform. For our production financial systems we now use a pSeries/AIX/SAP platform.
      So far in the zVM/SUSE/SAP POC, we have been able to create four zVM LPARS on IBM z9 hardware, create twelve zVM guests on those LPARS, boot SLES10 in those guests, install and run SAP instances in those guests using hipersockets for access to our DB2 SAP databases running on zOS, and direct user workloads to the SAP instances with good results. We have also successfully developed cloning scripts that have made it possible to create new SLES10 instances, configured and ready for SAP installs, in about 10 seconds using FLASHCOPY and IBM DASD.
      I am writing in the hope that you can direct us to technical resources at IBM/Novell/SAP who may be able to field a few questions that have arisen. In our discussions about optimization of the zVM/SUSE/SAP platform, we wondered if any wisdom about the appropriateness of and support for using zVM capabilities to virtualize SAP has ever been developed or any best practices drafted. Attached you will find an IBM Redbook and a PowerPoint presentation which describes the use of the zVM discontiguous shared segments and the zVM named saved system features for the sharing of reentrant code and other elements of Linux and its applications, thereby conserving storage and disk resources allocated to guest machines.   The specific question of the hour is, can any SAP code be handled similarly? Have specific SAP elements eligible for this treatment been identified?
      I've searched the SUSE Knowledgebase for articles on this topic to no avail. Any similar techniques that might help us reduce the total cost of ownership of a zVM/SUSE/SAP platform as we compare it to Intel Blade/Red Hat/SAP and pSeries/AIX/SAP platforms are of great interest as we approach the end of our POC. Can you help?
      Greg McKelvey is a Client I/T Architect at IBM. He found the attached IBM documents and could give a fuller account of our POC. Pat Downs, IBM zSeries IT Architect, has also worked to guide our POC. Akshay Rao, IBM Systems IT Specialist - Linux | Virtualization | SOA, is acting as project manager for the POC. Jim Hawkins is the Home Depot Architect directing the POC. I've CC:ed their email addresses. I am sure they would be pleased to hear from you if there are the likely questions about what the heck I am asking about here. And while writing, I thought of yet another question that I hoping somebody at SAP might weigh in on; are there any performance or operational benefits to using Linux LVM to apportion disk to filesystems vs. using zVM to create appropriately sized minidisks for filesystems without LVM getting involved?"
As you can see, implementation questions need to be resolved. We have heard from Novell that the SLES10 Kernel and other SUSE artifacts can reside in memory and be shared by multiple operating system images. Does SAP support this configuration? Also, has SAP identified SAP components which are eligible for similar treatment? We would like to make sure that any decisions we make about the SAP platforms we are building will be supportable. Any help you can provide will be greatly appreciated. I will supply the documents referenced above if they are not known to any answerer. Thanks, Al Brasher 770-433-8211 x11895 [email protected]

Hello AL ,
first, let me welcome you on board, I am sure you won't be disapointed with your choice to run SAP on ZOS.
as for your questions,
it wan't easy to find them in this long post , so i suggest you take the time to write a short summary that contains a very short list of questions.
as for answers.
here are a few usefull sources of information :
1. the sap on db2 for Z/os sdn page :
SAP on DB2 for z/OS
in it you can find 2 relevant docs :
a. best practices for ...
b. database administration for db2 udb for z/os .
this second publication is excellent , apart from db2 specific info , it contains information on all the components of the sap on db2 for z/os like zlinux,z/vm and so on ...
2. I can see that you are already familiar with the ibm redbooks , but it seems that you haven't taken the time to get the most out of that resource.
from you post it is clear that you have found one usefull publication , but I know there are several.
3. a few months ago I wrote a short post on a similar subject ,
I'm sure its not exactly what you are looking for at this moment , but its a good start , and with some patience you may be able to get some answers.
here's a link

Best practice for Error logging and alert emails

I have SQL Server 2012 SSIS. I have Excel files that are imported with Exel Source and OLE DB Destination. Scheduled Jobs runs every night SSIS packages.
I'm looking for advice that what is best practice for production environment.Requirements are followings:
1) If error occurs with tasks, email is sent to admin
2) If error occurs with tasks, we have log in flat file or DB
Kenny_I

Are you asking about difference b/w using standard logging and event handlers? I prefer latter as using standard logging will not always data in the way in which we desire. So we've developed a framework to add necessary functionalities inside event handlers
and log required data in the required format to a set of tables that we maintain internally.
