Universe Design Best Practices for Oracle

Hello All,
We recently moved from XIR2 on MS SQL 2005 to XI 3.1 on Oracle. This has been a difficult move for us as my team is new to oracle. I'm currently working on several performance issues between BOBJ and Oracle and am looking for documentation on best practices for universe design with oracle. I've foudn tidbits here and there regrading using parameters joing_by_sql and boundary_weight_table, wondering if there are other options out there that might help. We have queries taking 45+ minutes to run and that is totally unacceptable.
thanks
Andrea

I am not sure if you are looking for Optimization or anything else. sorry for that following link might help you considering Oracle as DB.

Best practice for oracle 10.2 RAC with ASM

Did any one tried/installed Oracle 10.2 RAC with ASM and CRS ?
What is the best practice?
1. separate home for CRS, ASM and Oracle Database?
2. separate home for CRS and same home for ASM and Oracle Darabase?
we set up the test environment with separate CRS, ASM and Oracle database homes, but we have tons of issues with the listener, spfile and tnsnames.ora files. So, seeking advise from the gurus who implimeted/tested the same ?

I am getting ready to install the 10gR2 database software (10gR2 Clusterware was just installed ) and I want to have a home for ASM and another for database as you suggest. I have been told that 10gR2 was to have a smaller set of binaries that can be used for the ASM home ... but I am not sure how I go about installing it. The first look at the installer does not seem to make it obvious...Is it a custom build option?

Symantec antivirus Best practice for oracle database on windows server 2003

Hi all,
I have an oracle database server on windows server 2003 platform of version 10.2.0.4. what would be best practice of running symantec antivirus on that server as well as database file exclusions from scanning them.
My server had rebooted unexpectedly for many times. in event log i have id as 6008. what may be cause of it..?

Normally, you don't run a virus scanner on a database server because your database server isn't vulnerable to viruses. It's behind firewalls, people aren't reading mail on it, people aren't plugging thumb drives into it, etc. If you do decide that you need to run a virus scanner on a database server, at least exclude the Oracle data files from the scan. Oracle gets very unhappy if someone else tries to open its data files (or, worse, if someone opens a data file before it gets the chance to acquire exclusive access).

Wireless Design - Best Practices for Data, Voice, and LBS

Hi,
I am currently in the process of designing a WLAN for a new hospital and I am getting some push back from my sales team. The requirements of the WLAN are data, voice, and location based services (RFID for medical equipment) ... needs to be 2.4 GHz for Guest and some apps/clients but primarily 5 GHz for most of the clients ... lastly needs to be N compatible for future use.
So, I did a predictive design with 1252's on the perimeter with 2.4 and 5 GHz patch antennas and 1142's in the middle to fill gaps ... I also scoped out 2 5508 for redundancy .... total design with -65 at my edges was 169. However, this is getting push back because of several cost issues ....
1. The bundle that Cisco offers for 5 100 AP license 5508 WLC is cheaper than buying 2 250 AP licenses WLC's ... which doesn't make any sense to me because I think 5 devices is over kill
2. The sales engineer is concerned about the power issues with the 1252's ... customer would rather not use power injectors ... and although they would have 6500's at there core ... they would only have basic switches in their IDF's so I wasn't sure which POE Switches would be able to handle 1252 but cost was an issue there as well
So, for my understanding when you are doing a WLAN design for LBS it's always best to have APs or antennas on the perimeter for better triangulation ... it makes more sense to me to do that with patch instead of Omni's ... however my sales engineer wants to use all 1142's ... so my question is what are the pro and cons behind using all Omni's or using Patch and Omni's?
Furthermore, if anyone has any documentation supporting why I would not use all Omni's that would be great because all the articles I have read on LBS just state that placement of APs is critical but doesn't give no specifics on whether it's a good practice to place them on the perimeter using a specific type of antenna or what.
Thanks in advance for you help and any ideas about this design!!!

1. The 5508 is expensive because it's alot faster than the 4400 plus there are some features exclusive to the 5508 such as OfficeExtend. As the old network design adage goes: Your design can be done correctly, cheap or fast. Choose two.
2. The 1250 requires 19.5w of power to enable FULL MCS rates to both radios. Only the 3560E, 3750E or the Sup720 is capable of supporting that. Upgrading the IOS of the 1250 to 12.4(10b)JDA3 will allow the AP to operate both radios at 15.4w BUT at a lower MCS rates. Correct placement of the AP and the correct use of the antennaes will also help in the signal distribution.
3. Patch antennaes are mostly directional. The 1140 is onmi-directional BUT the signal strength is not as powrful as the 1250 at full power. The AIR-ANT2451NV is an omni-directional patch designed for the 1250.

SAP Best practice for Oracle installation on HPux

Hi - I am looking for SAP best practices document to install ERP6 on Oracle 10G platform HPUNIX 31. Is there any sap best practices guide?
Also, for Dev system, I am planning to install ABAP and JAVA stacks in one database. What do I need to do in database level?
Last, How am I going to configure the 2 engines to communicate?
Any reference to documents will be appreciated.
Regards
k

Hi,
Sorry but I'm going to be a bit bold here.
All needed information is on the guides.
1) If you are on Windows, you put the SAP-Oracle CD/DVD in, execute the command mentioned on the installation guide type the two things mentioned on the guide and press next next next. Then you install SAP
2) if you are on UNIX, you start SAP installation, then it stops and tell you to install Oracle. The guide tells you to run RUNINSTALLER (in capitals) you type the two things mentioned on the guide and press next next next. Then you continue the SAP installation.
Of course, those are the simplified versions
No response file is generated "ever". The response file comes INSIDE the installation CDs, for that reason is very important to execute the EXACT commands mentioned on the installation guides, in order to use such, already existing, response file.
I do not understand this need of super-hiper detailed step by step guides.
If you get one like that, then it will be obsolete after one month because there are new Oracle parameters, new oracle patches/patch sets or new .... that have to be done

Resources for from design - best practices for layout?

Hi,
I have made a number of forms fo the past few years. I feel like they look dated and are somewhat stale...   I have found a few resources out there on Javascript best practices and more mechanical focused articles, but nothing really specific design as it relates to usability and "feel". I realized some of this is subjective and varies depending on the form's purpose, but I am just looking for some new ideas.
Does anyone have a resource or listing of froms they think are outstanidng from a design perspective?
Is anyone willing to share forms they think are outstanding? Just that baisics like information collection?
How much color and line type objects become to much?
What are some design elements used in "web 2.0" (whatver that really means) that we sould be using in our forms. tempered with what can be done.
I am looking for this to be an open disucssion and am curious to hear what works for others. I hope others will find this interesting and helpful.
Cheers,
Tom

And the second snippet code validates any form to check every fields if values are not null, if a value is null it will setFocus on the first null field
2. Validate Form and Focus on First Field that Fails Validation
     2.1 Create a script Object with two small methods to return a table of fields that have null values
Script Object :
form1.#variables[0].myForm - (JavaScript, client)
//Tab for field's expressions and field's exceptions
var tabExpression;
var tabException;
function validateAllFields(rootObject){
          //If a field is null, stop everything
          if (tabExpression.length > 0)
                         return;
          //If the 'presence' property is by default 'visible' in the form and the object value is 'visible', the 'presence' property doesn't exist
          //If its default value is "hidden", the property always exist
               if (!rootObject.isPropertySpecified("presence") || rootObject.presence == "visible"){
                              //Verify if the object contains an interface 'button'
                              //The button is considered as a 'field', so if it's not a button the statement is true
                              if (!(rootObject.isPropertySpecified("ui") && rootObject.ui.nodes.item(0).className == "button")){
                                             //If the object contains nodes and if it's not a 'field' or a RadioButtonList
                                             if (rootObject.nodes.length > 0 && (rootObject.className != "field" && rootObject.className != "exclGroup")){
                                                            //Recall this method for each nodes in the object to find every fields (Recursive Method)
                                                      for (var i = 0; i < rootObject.nodes.length; i++){
                                                                                validateAllFields(rootObject.nodes.item(i));
                                             //Verify to add the object in the list if the object is a field and if it contains a value
                                             if (rootObject.className == "field" || rootObject.className == "exclGroup"){
                                                            if (rootObject.rawValue == null || rootObject.rawValue == 0){
                                                                           //Variable to determines if the object is an exception field
                                                                           var boValidate = true;
                                                                           //If there's exception fields
                                                                           if (tabException.length > 0){
                                                                                          //Verify if the field is in the exception list
                                                                                          if (tabException.indexOf(rootObject.name) != -1){
                                                                                                   boValidate = false;
                                                  //Add if the object is not in the exception table
                                                  if (boValidate)
                                                            tabExpression[tabExpression.length] = rootObject.somExpression;
     2.2 Create this method in your object as well, and will be called on a click_event
function getValExpressions(rootObject, tabExcption){
     //Create new table
     tabExpression = new Array();
     //Put the exceptions fields value in the exception table
     tabException = tabExcption
     //Validation
     validateAllFields(rootObject);
     //Return a null field
     return tabExpression;
     2.3 The click event is where you write the special validation for different forms
//Create a table with exception fields, can be used for special validation fields or no validation
var tabExceptionFields = new Array("dateField1", "txtComments", "txtTotal");
//Call the validation
var tab = myForm.getValExpressions(Main, tabExceptionFields);
if (tab.length > ){
     xfa.host.setFocus(tab[0]);
} else{
     var boValidate = false;
     var strExpression;
     //write your validation according to the fields you need special validation.
     if (statement == false){
          strExpression = Reference_Syntax.Field.somExpression;
          boValidate = false;
      if (boValidate){
          xfa.host.print(1, "0", (xfa.host.numPages -1).toString(), 0, 0, 0, 0, 0);
     } else{
          xfa.host.setFocus(strExpression);
I will post a form template as an exemple for these function
Enjoy!

MPLS Design Best Practices for SP

When deploying a new MPLS backbone for a Service Provider, what will be consider the best practices in general? For example what about the following list and any other items:
- Define the Internet as a VRF?
- Use private ASNs?
- Define a VRF per special service?
- Use at least two route reflectors?
- Use OSPF as IGP?
- Limit the CE-PE routing support to OSPF and BGP?
What will be the best approach for management of the devices? A management VRF or the nodes to natively be on a management network?
What to consider when designing from scratch?

William some recommended practises, although you can point out your specific constraints in adopting any.
- Define the Internet as a VRF?
(Yes Logical speperation is the way to go.)
- Use private ASNs?
(No, use a Public AS, you may have to peer outside your AS in a VRF with other AS's)
- Define a VRF per special service?
(This is Perfect , Logical Seperation)
- Use at least two route reflectors?
(Right, atleast 2 and above that depends on the size of your network)
- Use OSPF as IGP?
(I dont see any problems with OSPF in scaling for big networks)
- Limit the CE-PE routing support to OSPF and BGP?
(This aspect shouldnt impact much really, you can very well support all the protocols, as its more of serving your customers, rather than dictating the conditions.
Yes have a seperate VRF for Device Managements (also give a thought for a management subnet, which would be unique across your network)
You should generally start with a overview topology, introdcution of the objectives. And then go ahead with the suggested phy topo,
And then move on to the logical services, beggining from Core IGP, then core BGP, and then all the add on protocols, multicast , MPLS TE etc/. Then you can cover specilized service and their logic and description in the end.
Pretty much, just simply think of building out right from scratch that is Physical Layer and Move to Layer 2 and then Layer 3 Layer 4 .
So basically you doc should be index in a manner following the sequence of the OSI layers, this gives a good flow to the doc. And rest remains is the description of the logic used in each service or deployment method, that would be your skill.

Swaroop

Portal Design - Best Practices for Role and Workset Tab Menu

We are looking to identify and promote best practices in SAP Portal Design.
First, is there a maximum number of tabs which should exist on the highest level tab menu, commonly called the role menu? Do a large number of tabs on this menu cause performance issues? Are there any other issues associated with a large number of tabs on this menu?
Second, can the workset tab menu be customized to be 2 lines of tabs? Our goal is to prevent tab scrolling.
Thanks

Debra,
Not aware of any performance issues with the number of tabs in the Level 1 or 2 menus, particularly if you have portal navigation caching enabled.
From an end user perspective I guess "best practice" would be to avoid scrolling in the top level navigation areas completely if possible.
You can do a number of things to avoid this, including:
- Keep the role/folder/workset names as short as possible.
- If necessary break the role down into multiple level 1 entry points to reduce the number of tabs in level 2.
An example of the second point would be MSS. Instead of creating a role with a single workset (i.e. level 1 tab), we usually split it into two folders called something like "My Staff" and My Finance" and define these folders as entry points. We therefore end up with two tabs in level 1 for the MSS role, and consequently a smaller number of tabs in level 2.
Hope that helps......
Regards,
John

AIX 5.3 best practices for oracle DB 10.2.0.4

customer is using AIX 5.3 (AIX PROD_aix 3 5 000CA2A2D900) and DB version is 10.2.0.4
DB is critical & Recently getting migrated to AIX from WIndows.
To make sure we don't face any probs after migration,we are implementing best practices at OS level .. so far we've implemented following.
1)All dbf's are existing on JFS2 filesystem -- We've enabled CIO for mount points(dbf's,redo's)
2)Changed the AIX_THREAD_SCOPE to S , previously AIX_thread_scope was set to P
3)Changed minperm% to 5% and maxperm% to 20%
Do we need to change the memory page size to best fit DB needs? or do we need to use large pages?,Any Document available from IBM? what is default pagesize used(how to check)?
How to check NIC is 100mbps or 1gbps?what is the command.
thanks in advance..

IBM whitepaper "Oracle Architechture and Tuning on AIX" might be a good starting point. Not just a list of "magic" settings, but some real content as well.
Some comments about the settings you've implemented so far:
1) Be sure to use an allocation unit size of 512B for filesystems storing redo logs and control files, it's required for direct i/o to work correctly.
3) Since you're using CIO, it might be a good idea to set VMM to steal only file pages (lru_file_repage).
As for the large pages, you have quite a few options. Smaller large pages can be handled more dynamically, whereas bigger ones can provide more performance gains, but can also cause problems if you over-allocate. But, if you didn't need to use large pages on Windows, chances are that you might not necessarily need them on AIX either.
And as always, be careful with "best practices" and "rules of thumb"; it's far better to test different configurations thoroughly than to blindly rely on generic recommendations based on Codd knows what.

UCS Design Best practice for vMotion

hi,
We are deploying a new UCS domain with 8 chassis and 50/60 B200M3 for installed an VMware infrastructure 5.0
For each ESXi, we need :
2 vNIC dedicated to Management Network
2 vNIC dedicated to vMotion
4 vNIC dedicated to srv
These vNIC will be configured into Template Service Profile deployed to all B200M3.
For each pair of vNIC, a vNIC used fabric A, a vNIC used fabric B.
We could have vMotion between all server.
The VMware vSwitch will used either vNIC_A or vNIC_B such as VM and loadbalancing algo.
Do we have a design in order to confine the vMotion vlan to UCS domain ? I means to not trunk dedicated vMotion Vlan on uplink
Many thks for your advice.
Best regards.
Nicolas.

No need to change anything on UCSM side for the vMotion requirment. All required is that the vmnic which corresponds to FI-A is set as primary on each host for the VMkernel used for vMotion. This keeps all vmotion traffic local to one FI without leaving the system.
At any time if you lost an adapter, IOM or FI, they traffic would failover to the standby vmnic assigned to the vmkernel - so you will have full redundancy - you're simply setting a sticky "preference" of which link to use. In the case where you lost IOM-A on Chassis 2, that VMotion traffic would then traverse the northbound network to reach the other fabric - not a big deal as vMotion is not that bandwidth demanding.

Best Practice for starting & stopping HA msg nodes?

Just setup a cluster and was trying to start-msg ha and getting error about watcher not being started. Does that have to be started separately? I figured start-msg ha would do both.
For now I setup this in the startup script. Will the SMF messaging.xml work with HA? Whats the right way to do this?

Best Practice for Extracting a Single Value from Oracle Table

I'm using Oracle Database 11g Release 11.2.0.3.0.
I'd like to know the best practice for doing something like this in a PL/SQL block:
DECLARE
    v_student_id    student.student_id%TYPE;
BEGIN
    SELECT student_id
    INTO    v_student_id
    FROM    student
    WHERE   last_name = 'Smith'
    AND     ROWNUM = 1;
END;
Of course, the problem here is that when there is no hit, the NO_DATA_FOUND exception is raised, which halts execution. So what if I want to continue in spite of the exception?
Yes, I could create a nested block with EXCEPTION section, etc., but that seems clunky for what seems to be a very simple task.
I've also seen this handled like this:
DECLARE
    v_student_id    student.student_id%TYPE;
    CURSOR c_student_id IS
        SELECT student_id
        FROM    student
        WHERE   last_name = 'Smith'
        AND     ROWNUM = 1;
BEGIN
    OPEN c_student_id;
    FETCH c_student_id INTO v_student_id;
    IF c_student_id%NOTFOUND THEN
        DBMS_OUTPUT.PUT_LINE('not found');
    ELSE
        (do stuff)
    END IF;
    CLOSE c_student_id;
END;
But this still seems like killing an ant with a sledge hammer.
What's the best way?
Thanks for any help you can give.

Do not design in order to avoid exceptions. Do not code in order to avoid exceptions.
Exceptions are good. Damn good. As it allows you to catch an unexpected process branch, where execution did not go as planned and coded.
Trying to avoid exceptions is just plain bloody stupid.
As for you specific problem. When the SQL fails to find a row and a value to return, what then? This is unexpected - if you did not want a value, you would not have coded the SQL to find a value. So the SQL not finding a value is an exception to what you intend with your code. And you need to decide what to do with that exception.
How to implement it. The #1 rule in software engineering - modularisation.
E.g.
create or replace function FindSomething( name varchar2 ) return foo.col1%type is
id foo.col1%type;
begin
select col1 into id from foo where col2 = upper(name);
return( id );
exception when NOT_FOUND then
return( null );
end;
And that is your problem. Modularisation. You are not considering it.
And not the only problem mind you. Seems like your keyboard has a stuck capslock key. Writing code in all uppercase is just as bloody silly as trying to avoid exceptions.

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.

How about computer desktop or computer workstation with the latest version has CPU supports Oracle VM or SPARC?Nope. The only place you find SPARC T4 processors is in Sun Servers (and some Fujitsu servers, I think).
