Best Practice - WAP connecting switchport configuration.

Is there a best practice for deploying the WAP's in a WAP/WLC infrastructure? Should the connecting switchport be an Access port or a Trunk port? I've seen this implemented in both fashions and wasn't sure if one was a better choice than the order. What is the difference?
My other question is regarding applying additional switchport configurations. Is there anything wrong with applying either spanning-tree portfast, spanning-tree bpdguard, or switchport port-security.

Hi Ken,
Access port all the time, everywhere, UNLESS the AP is configured for HREAP/FLEX then trunk. Or if you deploy a AP in monitor mode then TRUNK.
QOS -- if its access port trust dscp. If you truck trust cos.
No you are fine. Portfast is highly recommended.

What are the best practice for CQ5.5 configuration?

Hello,
What are the best practice for CQ5.5 configuration which handle for High availability.
Last time I had a issues on server when I was uploaded 2 GB of DAM and then after that the server is not able to start and always getting error regarding Tar Persistance.
So kindly request you to please let me know what are the best apache felix configuration.
Thanks in advance...

Satish

Hi,
A DAM upload, regardless of the size of the assets, never should result in TarPM problems, unless you run into an OOM, which left the repository in an unclean state. So if you regularly do DAM uploads of that size, you should check the Garbage Collection logs and probably adjust the heapsize if necessary. You might want to limit the number of concurrent running workflows to keep the memory consumption a bit lower.
To your question: HA in a traditional sense you cannot achieve with a single box, even with optimized settings. In an author usecase you would need clustering.

Best practices for connecting to DB

Hi,
I am having 3 different java classes which will contact the DB for getting the data from the table. I wrote a separate java class for DB connection like this :
public class DBConnection {
private Connection con;
public Connection getConnection() {
try {
Class.forName("org.apache.derby.jdbc.ClientDriver");
con = DriverManager.getConnection("jdbc:derby://localhost:1527/StrutsDB", "username", "password");
} catch (SQLException ex) {
Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
} catch (ClassNotFoundException ex) {
Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
return con;
How to use this single connection object in all of the 3 classes? What are all the ways of doing so?
Is there any best practices for connecting to DB?
Thanks in advance,

The problem with "best practice" is it really depends on your situation. If you are creating a single user, desktop application then what you are doing will work but would be more efficient if the connection was declared as static and you used the singleton pattern.
public class DBConnection {
    private static final Connection con;
    private DBConnection() {
        try {
            Class.forName("org.apache.derby.jdbc.ClientDriver");
            con = DriverManager.getConnection("jdbc:derby://localhost:1527/StrutsDB", "username", "password");
        } catch (SQLException ex) {
            Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
    public static Connection getConnection() {
        return con.
}The private constructor guarantees only one instance of the class will be created (since you can't use 'new' to create one) and initialized the database connection. Then any other object that require a connection simply call DBConnection.getConnection() and they will get the same database connection each time.
Note that this is a little simplistic and is not thread safe. If your classes will be executing on different threads you will need a more sophisticated approach. You will also need to make sure you commit or rollback any transactions when done or the next time you get the connection you may be in the middle of an existing transaction.

What is the best Practice JCO Connection Settings for DC Project

When multiple users are using the system data is missing from Web Dynpro Screens. This seems to be due to running out of connections to pull data.
I have a WebDynpro Project based on component development using DC's. I have one main DC which uses other DC's as Lookup Windows. All DC's have their Own Apps. Also inside the main DC screen, the data is populated from multiple function modules.
There are about 7 lookup DC Apps accessed by the user
I have created JCO destinations with following settigns
Max Pool Size 20
Max Number of Connections 200
Before I moved to DC project it was regular Web Dynpro Project with one Application and all lookup windows were inside the same Project. I never had the issue with the same settings.
Now may be becuase of DC usage and increase in applications I am running out of connections.
Has any one faced the problem. Can anyone suggest the best practice of how to size JCO connections.
It does not make any sense that just with 15-20 concurrent users I am seeing this issue.
All lookup components are destroyed after its use and is created manually as needed. What else can I do to manage connections
Any advise is greatly appreciated.
Thanks

Best practice for repositories during configuration - one or several DBs?

Establishing my 11.1.2 dev box, we are in 9.3.1 in Production. Reading through documentation it states that one database is the repository for the Shared Services, Business Rules, Essbase, etc.
Since I came to this new job with 9.3.1 installed not sure if this was verbiage that is the standard from version 9.3 or this is something new for 11.1.x
So...what is the best practice? is it better to lump all foundation type activity into one DB (I realize Planning apps have their own db) or is it better to have a db for biplus, db for shared services, etc...
JTS

Here is what Oracle have to say
"For ease of deployment and simplicity, for a new installation, you can use one database for all products, which is the default when you configure all products at the same time. To use a different database for each product, perform the “Configure Database” task separately for each product. In some cases you might want to configure separate databases for products. Consider performance, roll-back procedures for a single application or product, and disaster recovery plans."
I would say in a development environment then there is no harm in using one db/schema for products, remember some products require separate databases/schemas e.g. Planning application.
In production environment I tend to promote keeping them separate as it helps with troubleshooting and recovery.

Best Practices for Connecting to WebHelp via an application?

Greetings,
My first post on these forums, so I appologize if this has already been covered (I've done some limited searching w/o success). I'm developing a .Net application which is accessing my orginazation's RoboHelp-generated webhelp. My organization's RoboHelp documentation team is still new with the software and so it's been up to me to chart the course for establishing the workflow for connecting to the help from the application. I've read up on Peter Grange's 'calling webhelp' section off his blog, but I'm still a bit unclear about what might be the best practices approach for connecting to webhelp.
To date, my org. has been delayed in letting me know their TopicIDs or MapIDs for their various documented topics. However, I have been able to acquire the relative paths to those topics (I achieved this by manually browsing their online help and extracting out the paths). And I've been able to use the strategy of creating the link via constructing a URL (following the strategy of using the following syntax: "<root URL>?#<relative URI path>" alternating with "<root URL>??#<relative URI path>"). It strikes me, however, that this approach is somewhat of a hack - since RoboHelp provides other approaches to linking to their documentation via TopicID and MapID.
What is the recommended/best-practices approach here? Are they all equally valid or are there pitfalls I'm missing. I'm inclined to use the URI methodology that I've established above since it works for my needs so far, but I'm worried that I'm not seeing the forest for the trees...
Regards,

PS: we're using RoboHelp 9.0

I've been giving this some thought over the weekend and this is the best answer I've come up with from a developer's perspective:
(1) Connecting via URL is convenient if (#1) you have an established naming convention that works for everyone (as Peter mentioned in his reply above)
(2) Connecting via URL has the disadvantage that changes to the file names and/or folder structure by the author will break connectivity
(3) Connecting via TopicID/MapID has the advantage that if there is no naming convention or if it's fluid or under construction, the author can maintain that ID after making changes to his/her file or folder structure and still maintain the application connectivity. Another approach to solving this problem if you're working with URLs would be to set up a web service that would match file addresses to some identifier utilized by the developer (basically a TopicID/MapID coming from the other direction).
(4) Connecting via TopicID has an aesthetic appeal in the code since it's easy to provide a more english-readable identifier. As a .Net developer, I find it easy and convenient to construct an enum that matches my TopicIDs and to utilize that enum to construct my identifier when it comes time to make the documentation call.
(5) Connecting via URL is more convenient for the author, since he/she doesn't have to worry about maintaining IDs
(6) Connecting via TopicIDs/MapIDs forces the author to maintain those IDs and allows the documentation to be more easily used into the future by other applications worked by developers who might have their own preference in one direction or another as to how they make their connection.
Hope that helps for posterity. I'd be interested if anyone else had thoughts to add.

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

What is the best practice for connecting to different schemas?

Hi all,
We are porting an application from SQL Server to oracle and would like to know what the best practices are in oracle for user connections to an Oracle instance.
More or less the question could be put like this:
1) The equivalent of a SQL Server Database in Oracle is a Schema. (more or less)
2) A specific application has it's own schema where it keeps all related objects (Tables, etc)
3) In SQL Server you grant access to the Database and its objects (Tables, etc) to all users of the application.
4) In Oracle do you grant access to the Schema and its objects (Tables, etc) to all users of the application also? Or do all users log
in as the schema owner?
So in Oracle if there existed [SchemaApplication].[table1], how would [userChris] and [userDave] query [SchemaApplication].[table1]?
Would Chris and Dave log in as [userChris] and [userDave], or would they normally log in as [userApplication]?
finally, is it good practice to log in as a unique user eg [userChris] and then issue the
alter session set current_schema = shemaApplication;
command to change the way references to tables are interpreted?

4) In Oracle do you grant access to the Schema and its objects (Tables, etc) to all users of the application also? Or do all users log
in as the schema owner?There are ways to implement the same.
Case 1.
Create different roles, such as APP_ROLE, READONLY_ROLE. Create public synonym for objects in SchemaApplication user. Grant these role to single user say appUser this is different from you SchemaApplication user. Use appUser to connect to application and for different user like userChris, userDave provide another layer of security. Say userDave is allowed only to deal with cash related transaction, so allow him to open only those screens which are related to cash transaction only.
Case 2.
Create public synonym and grant privilege on tables from SchemaApplication to different users (say userChris, userDave).
So in Oracle if there existed [SchemaApplication].[table1], how would [userChris] and [userDave] query [SchemaApplication].[table1]?This is resolved by public synonym. There are private synonym as well, you can create this also but in this case you have to create private synonym for each of the users.
Would Chris and Dave log in as [userChris] and [userDave], or would they normally log in as [userApplication]? I would suggest you to connect either using a new user(Case 1) or the user itself has account in the database(Case2).
finally, is it good practice to log in as a unique user eg [userChris] and then issue the
alter session set current_schema = shemaApplication;
No. It is not a good practice to allow the user to login to database using the application owner.
command to change the way references to tables are interpreted?The public/private synonym can be used to resolve the schema.object value. For example, if SchemaApplication has table T, then you can create public synonym as 'CREATE PUBLIC SYNONYM T FOR SchemaApplication.T'; and now you can refer this table as T from any other schema(user).

What are best practices for connecting asa to nexus 5000

just trying to get a feel for the best way to connect redundant asa to redundant nexus 5000
using a vpc vlan is fine, but then running a routing protocol isn't supported, so putting static routes on 5000 works, but it doesn't support ip sla yet so you cant really stop distributing the default if your internet goes down. just looking for what was recommended.

you want to test RAC upgrade on NON RAC database. If you ask me that is a risk but it depends on may things
Application configuration - If your application is configured for RAC, FAN etc. you cannot test it on non RAC systems
Cluster upgrade - If your standalone database is RAC one node you can probably test your cluster upgrade there. If you have non RAC database then you will not be able to test cluster upgrade or CRS
Database upgrade - There are differences when you upgrade RAC vs non RAC database which you will not be able to test
I think the best way for you is to convert your standalone database to RAC one node database and test it. that will take you close to multi node RAC

Best Practices Pseudo-Time Clock Configuration

Friends,
I Find for a manual of best practices for configuration PSEUDO_TIME CLOCK GET VPN.

Hi,
GET VPN uses time-based anti-replay (TBAR), which is
based on a pseudo-time clock that is maintained on the KS. An advantage of using pseudotime for
TBAR is that there is no need to synchronize time on all the GET VPN devices using NTP.

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

Best Practice SAP connection

Hello All
I am just starting creating reports with CR2008 connected to SAP ECC 6.0. I am suffering some performance issues when trying to create a report on tables VBAK, VBAP and LIPS. Report performance is extremely slow. I have a few questions on this:
1. Can anyone point me to some documentation that would help me set up SAP and CR2008 for improved performance when reporting directly on tables.
2. Performance wise Is it better to report on an Classic Infoset rather than directly on a table in CR2008
Any other tips would be greatly appreciated.
Thanks

Best practice for .war? Configure and deploy or deploy and configure?

In Apache Tomcat for example, I can deploy an app, stop the server, reconfigure the app in situ, then start the server again...
Is this recommended for deploying Java web apps to Oracle App Server 10g?
We currently have a consulting firm that is recommending to configure the web app before deploying. Sounds reasonable, except that they want this done via JDeveloper so that the Sys Admin can right click on the "deploy to OAS" button (ie: have the tools generate the .war file after configuration and deploy automagically).

Thanks for your feedback.
Are you aware of any way to use the *.deploy configuration file that is created by JDeveloper in an ANT script to create the .war or .ear file?
If not, I can picture the Sys Admin and developers groaning when they're told that they're JDeveloper web-app configuration cannot be used for production -- and that they must somehow duplicate that functionality in an ANT script!
I do have the below ANT scripts from Debu to do the deployment etc. But they only help after the .ear is built.
EAR file deployment:
<target name="deploy" depends="core">
<java jar="${j2ee.home}/admin.jar" fork="yes">
