Why do i need the "Removeable Rechargable Li-Ion Battery" ?He

Well, i couldn't find a store, where i could buy a new battery for my Zen Micro!! So why do i need this revmoveable battery(i dont have the "limited edition")..
Thanks... (sorry for my English)

You don't need to buy one, even if yours is not limited edition, your Zen Micro should have come with one "removeable rechargeable Li-Ion Battery". Did yours not come with a battery?

Oracle recommends that you do not use the default SPFILE names because all instances must use the same file and they all have different SIDs. Instead, store the SPFILE on Oracle ASM. If you store the SPFILE on a cluster file system, then use the following naming convention for the SPFILE: $ORACLE_HOME/dbs/spfiledb_unique_name.ora. Create a PFILE named $ORACLE_HOME/dbs/initsid.ora that contains the name SPFILE=ORACLE_HOME/dbs/spfiledb_unique_name.ora.

Why do we need the HWM?

hi,
why do we need the HWM? Does the CBO use it? I mean, if we're doing a FTS, then the first unformatted block we hit in a MSSM tells us all blocks above it are unformatted, so we dont read anymore, so what is the use of the HWM?
thanks

(as implied by the question) I would think that FTS uses HWM because it exists.
2) Are all 'unused blocks' unformatted? Does that imply that something 'unformats blocks' when you drop a table?
3) What happens when you truncate a table?
4) My thought is that HWM is more for providing a starting position for Direct Path Inserts than anything else.

Why do we need the @EJB annotation at the class level?

Why do we need the @EJB annotation at the class level?
Eg: Why do we need the first piece of code, when the second code seems much simpler .
*1.*
@Stateful
@EJB(name="ejb/TradeLocalNm",
beanInterface=TradeLocal.class)
public class TradeClientBean implements TradeClientRemote {
*2.*
@Stateful
public class TradeClientBean implements TradeClientRemote {
@EJB private TradeLocal trd;
}

I think it is possible to do it in an aggregated level however you need to define your distribution rules in order to get the desired result, you need also to consider that if distribution rules changes and the value after promotional planning returns the same value, it is possible that detailed level are not realigned to the new distribution rule (e.g. regarding another ratio).
Maybe this is one of several causes.

I have os 10.4. Why do I need the mac box set to upgrade to snow leopard?

I have os 10.4. Why do I need the mac box set to upgrade to snow leopard? What happens if I upgrade with just a 10.6 upgrade?

You can usually get those from the original grey installer discs that came with your Mac without bothering with Pacifist. Look for an 'installed bundled software' or similarly named item on one of those discs, generally the #1 disc. Run that & the original versions of those apps that were bundled with your Mac will be installed. Software Update will let you know if there is an update you can download for them (but of course that won't include an upgrade to a more recent major version, which you would have to buy separately).

What am I doing wrong with the isNew() method? and why do I need the other methods?

I have coded an include jsp like this.
          <%@page language="Java"%>
          <%@page import="javax.servlet.http.HttpSession"%>
          <%!
          String iContextPath;
          String iCommonPath;
          String iImagesPath;
          %>
          <%
          iContextPath = request.getContextPath();
          iCommonPath = iContextPath + "/common";
          iImagesPath = iCommonPath + "/images";
          System.err.println(" here ");
          HttpSession thisSession = request.getSession( false );
          if( thisSession.isNew() ){
          System.err.println("isnew");
          response.sendRedirect( iContextPath + "/common/login.jsp" );
          %>
          Now I also have a redirect.jsp in the root of an application that contains
          this.
          <html>
          <body>
          <%
          System.err.println("Redirecting at this time from the root");
          response.sendRedirect( request.getContextPath() + "/secureArea/");
          %>
          </body>
          </html>
          And I have a logout.java servlet that looks like this.
          package com.pch.epics;
          import java.io.IOException;
          import javax.servlet.ServletException;
          import javax.servlet.http.HttpServlet;
          import javax.servlet.http.HttpServletRequest;
          import javax.servlet.http.HttpServletResponse;
          import weblogic.servlet.security.ServletAuthentication;
          public class Logout extends HttpServlet{
          private static final String CONTENT_TYPE = "text/html";
          //Initialize global variables
          public void init() throws ServletException{
          //Process the HTTP Get request
          public void doGet( HttpServletRequest request, HttpServletResponse
          response ) throws ServletException, IOException{
          String username = "";
          if( request.getUserPrincipal() == null ){
          username = "Unknown";
          } else {
          username = request.getUserPrincipal().getName();
          System.err.println( "ePics logging out '" + username + "'" );
          request.getSession( false ).invalidate();
          ServletAuthentication.logout( request );
          ServletAuthentication.invalidateAll( request );
          ServletAuthentication.killCookie( request );
          response.sendRedirect( request.getContextPath() );
          //Process the HTTP Post request
          public void doPost( HttpServletRequest request, HttpServletResponse
          response ) throws ServletException, IOException{
          doGet( request, response );
          //Clean up resources
          public void destroy(){
          First of all, why won't the isNew() report a new session in the server log?
          EVERY request coming in says it's an old request (ie it's not new). The
          J2EE Applications and BEA WebLogic Server book from BEA says this should
          work.
          My second question is why do I need to do those three lines from
          ServletAuthentication to logout a user? Ok, maybe I'm from the MS world,
          but that seems excessive, especially since I've already done a
          session.invalidate() right before it, but the bea docs say I'm required to
          do all four!


When you invalidate a session. You invalidate the session of the web
          application that your jsp/servlet is part of. It is possible to have more
          than one web application on WLS and have them share a authentication info.
          While these applications share authentication they do not share their
          sessions so because of that calling session invalidate does not kill all the
          sessions. ServletAuthentication is needed to kill all the sessions and do a
          complete logout from WLS.

Why do we need the "Modify Date" column?

The subject says it all. Why do we need that column? It just occupies real estate.

I don't mean to be critical of you, Dave, but a "That's just the way it is" response leads to apathy, and apathy leads to junkware, and junkware leads to hate...
Nobody needs the modification date to be on the screen.

Does it hurt to leave the MBP with Lithium Ion battery plugged in?

I have been told by the local Apple Store Genius Bar that I should cycle the Lithium Ion battery down and then charge it back up to increase battery life. I thought that this was not necessary with a Lithium Ion battery. What is the truth here? I use my MBP on my desk most of the time and it is easier to keep it plugged in.
Does it really affect battery life?

tonefox,
Some of your recommendations are out of date:
It is suggested you run it down until the phone powers down and then charge it right up to 100% occasionally. But that is only to recalibrate the oercentage readout.
OP has an MacBook Pro, not a phone, and User calibaration ceased to exist with the 2009 MacBook Pros according to this article:
http://support.apple.com/kb/HT1490
To veehbg,
Anna's link to that artilce is very important to good battery life. I've been around here a long time and the number of batteries that failed early from lack of use far exceeds those that failed for any reason when the usage patterns outlined in that article were followed. i try to run my Mac portables on battery for 30 mins to a hour a day to keep thenm exercized. So dar, so good!

Java and Tomcat: Why do I need the port number when accessing Tomcat?

My ultimate goal is to setup a website that displays data from a database. I will use Java, Apache, Oracle, and whatever else I need to create a website the uses servlets, JavaServer Pages, and JDBC.
I�ve got four Pentium III computers:
1. Windows 2000 Server to be the web server (MyWebServer, IP = 10.10.1.1).
2. Windows 2000 Professional to be the database server (MyDatabaseServer, IP = 10.10.1.2).
3. Windows 2000 Professional that I use to develop and test (MyDeveloperPC, IP = 10.10.1.3).
4. Windows 2000 Professional that I use as a client to connect to the website (MyClientPC, IP = 10.10.1.4).
I installed Java Web Services Developer Pack on MyWebServer. It requires Java 2 Standard Edition (J2SE), so I installed that first. The files I downloaded and installed are as follows:
J2SE: j2sdk-1_4_0-rc-win.exe
JWSDP: jwsdp-1_0-ea1-win.exe
After installing these products, I set the environment variables as follows:
JAVA_HOME = c:\j2se
JWSDP_HOME = c:\jwsdp
Path = c:\j2se\bin;c:\jwsdp\bin; [and other previous statements]
On MyWebServer I start Tomcat (from the JWSDP menu option). It starts properly (as far as I can tell).
Then, from MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1
�The page cannot be displayed�.
I then try again and add the port number:
http://10.10.1.1:8080
This displays the page c:\jwsdp\webapps\root\index.html.
Here�s my question: Why do I have to enter the port number to get a page displayed? Do I have to have Apache HTTP Server running on MyWebServer to display pages without entering the port number?
Thanks for your help.

When you web server is running at the default Http Port, then you do not have to specify the port yourself.(The browser does it automatically)
So if you run your web server at port 80, then you will not have to specify the port explicitlyin the url.
If you want to use tomcat only as a jsp/servlet processing engine then install a web server (either IIS, or apache web server) and run it on port 80. (so that you dont have to specify the port)
Now configure tomcat to run as a servlet engine for this web server. for this refer to the tomcat documentation.
If you do not want to have an external webserver then you can configure tomcat itself to run at port 80 (in this case tomcat would do the work of both the web server as well as jsp/servlet engine... but this is not the setup for a production site). this can be done by changing the server.xml file in the conf directory of tomcat installation.
hope this helps.
regards,
Abhishek.

Why do i need the Microsoft Loopback Adaptor on XP

I just received a new PC running XP pro at work. This new PC replaced my old PC running win 2k. I installed XE as a domain user and it installed and ran without any issues. Now i try to install XE on XP pro and the listener will not start for port 8080 or any other port. Why would this new PC have this problem? Both PCs are configured to use DHCP.
Thanks,
Christopher

Hi
Please have a look into the following to understand Loopback Adapter and DHCP:
What is a Loopback Adapter?
The Microsoft Loopback adapter is a testing tool for a virtual network environment where network access is not available. Also, you must use the Loopback adapter if there are conflicts with a network adapter or with a network adapter driver. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information. The Loopback adapter is a useful tool for testing the configuration of network protocols such as TCP/IP on a local system when you don't have a network card.
DHCP is a protocol used by networked computers (clients) to obtain IP addresses and other parameters such as the default gateway, subnet mask, and IP addresses of DNS servers from a DHCP server. It facilitates access to a network because these settings would otherwise have to be made manually for the client to participate in the network.
The DHCP server ensures that all IP addresses are unique, that is, no IP address is assigned to a second client while the first client's assignment is valid (its lease has not expired). Thus IP address pool management is done by the server
The Dynamic Host Configuration Protocol (DHCP) automates the assignment of IP addresses, subnet masks, default gateway, and other IP parameters. The assignment occurs when the DHCP-configured machine boots up or regains connectivity to the network. The DHCP client sends out a query requesting a response from a DHCP server on the locally attached network. The query is typically initiated immediately after booting up and before the client initiates any IP based communication with other hosts. The DHCP server then replies to the client with its assigned IP address, subnet mask, DNS server and default gateway information.
The assignment of the IP address generally expires after a predetermined period of time, at which point the DHCP client and server renegotiate a new IP address from the server's predefined pool of addresses. Typical intervals range from one hour to several months, and can, if desired, be set to infinite (never expire). The length of time the address is available to the device it was assigned to is called a lease, and is determined by the server.
DHCP is intended for client PCs, not servers. It also suggests when DHCP is suitable: when there are lots of client machines to be configured So if you work in the server room of a corporation, you may well think that you have a large number of servers which need IP addresses to be allocated... but generally, for most corporate networks, the number of servers will be relatively small. And they also tend to all be physically co-located in one, large, rather chilly, server room. There is therefore no need for servers to have dynamically-assigned IP addresses.
One more way to understand DHCP: DHCP is a protocol that lets network administrators centrally manage and automate the assignment of IP Addresses on the corporate network. When a company sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine. Without DHCP, the IP address must be entered manually at each computer .
The key features of DHCP are listed as central management of IP addresses.

When and why do we need the object 'dimension' created by OWB

Hi
When we generate code for a dimension along with the ddl for the table
a dimension object with a post fix of _DIM is being generated. Do we need to
deploy this. Why do we require this and What is its impotance.
May be this is a basic doubt but will be thanfull if someone can tell me its importance
Thanks
Nanda Kishore

Nanda,
A dimension object has built in definitions of a parent-child relationship between pairs of column sets ("levels" of the dimension hyerarchy). The optimizer uses these relationships with materialized views to perform query rewrite and thus makes the queries more efficient.
For more details, please refer to the Oracle data warehousing guide:

Why do I need the disk

I downloaded Adobe Design Premium 5.5 from the Adobe site, installation seems to go well, I put in the serial number. After spending a short time "calculating", I get the message to "Please insert disk AdobeDesignPremium 5.5-English to continue"?

I was trying to run it both from an external and the desktop. I eventually found that the folder needed to be on the root C: drive. All works fine, thank you for your prompt reply.

Why do we need the "Trusted Application" in 11.1.2.1?

Hello,
We're upgrading from 9.3.1 to 11.1.2.1. In the process of testing I've discovered that for our CORPLOAD group users cannot see the HFM reports in 11.1.2.1 unless we add the "trusted application" role.
This is not the case in our current production (9.3.1). Does anyone have any idea why?
Regards
Dave
FYI the roles assigned to Reporting and Analysis are:
- analyst
- data source publisher
- personal page publisher
-provisioning manager (this is new as well).
- report designer
- trusted application
For reference the help says that trusted application means, but I don't understand what it means:
"Enables credentialed client-server communication of Interactive Reporting database connection files (.oce extension) that encapsulate connectivity, database type, network address, and database user name information"

Hi
I tried to replace with other working environment but we have only one 11.1.2.2 environment where as all the other servers are on 11.1.2.1 ( where I cannot find the adf folder itself).
The only option that left out would be to modify this xml. Have taken the backup, can you please tell me if this is the port defined ?
In planning,the xml file looks like below,

Why do we need the combination of Apache and Tomcatt?

Both Apache and Tomcatt are web servers. It is possible to get the ob done with any of them. Then, why do we go for the combination of Apache and Tomcatt in most of the Applictions? What is the significance of doing it?

The Apache Web Server is a high-performance HTTP server, which is very good in serving static content (i.e., HTML pages, JPG files, etc.).
Apache Tomcat is a servlet container written in Java. It includes an HTTP server, but it isn't optimized as much as the Apache Web Server and probably doesn't have as many configuration options as the Apache Web Server.
Often people use Apache Web Server as the primary HTTP server, and run Tomcat on top of that. You can configure Apache so that it redirects requests for servlets and JSPs to Tomcat. Apache Web Server cannot run servlets and JSPs by itself.

Why do we need the table TCURF?

Hi Friends,
Can't we get our currency translation job done without our sweet currency factors table TCURF. Say we want to convert fig's from FROM curr to TO curr at Daily avg rate (M) and we have an exchange rate as 2,642.34. Factors for this currency combination for M in TCURF are say 100,000:1.
Now my question is can't we have an exchange rate of 0.02642 and not at all use the factors from TCURF table?.
I suppose we have to still maintain factors as 1:1 in TCURF table if we are using exchange rate as 0.02642. am I right?. But why is this so?. Can't I get rid off TCURF.
What is the use of TCURF co-existing with TCURR.
Please enlighten me!!
Thanks
Raj

Hi Simon,
So now I can say to whole word what is the use of TCURF existence....am I right!!
Thanks you for sharing the knowledge.
