Data affinity between clusters separated via WAN

Hi,
I need your help, again! :)
In the scenario where I have two clusters separated via WAN, I want to know if it is possible to create data affinity to each cluster.
That is, this scenario is not the same as Push Replication Pattern solve, because I want to avoid the data management conflict between the updates on the both clusters. If I create data affinity to each cluster, the Cluster A is responsible for data objects X and Y (and the same data object in the other cluster is considered as secondary/backup) and Cluster B is responsible for data objects W and Z (also has a backup on Cluster A).
Thanks.

André

Hi ggleyzer,
Thanks for the help.
But, how can I routing different keys to different caches, if I want to have two clusters with the same information and caches due to possible disaster recover scenario?
The scenario that I imagine is almost the same as Push Replication Pattern - Active-Active. (http://coherence.oracle.com/display/INCUBATOR/Auction+Site+Demo+1.0.0)
I want to have 2 Clusters (e.g. "A" and "B") and have exactly the same information in each one. However, I want to create affinity of objects to each Cluster, for example, the objects X and Y are processed by "ClusterA" (even the request arrive to "ClusterB") but still have of copy of them in "ClusterB" (X' and Y', just for the case of disaster). So: can I specify the namedCache of "ClusterA" to objects X and Y (having a copy of that objects on "ClusterB") and assure that all processing of this type of objects are done by "ClusterA"?
If it's possible, do you think that approach is more suitable than Push Replication Pattern? A problem that occurs with this pattern is the Conflit Resolver. However, I don't know which problems I will face with the other. Maybe the main disadvantage is the information crossed over the WAN, because "ClusterB" can send processing to objects that has affinity to "ClusterA".
Thanks,
Regards,
André

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

Remote Desktop cannot verify the identity of the computer because there is a time or date diffrence between your computer and remote computer

Hello.....
I'm not able to log into Windows Server 2008 r2 server thorugh Remote Desktop connection, receiving below error message.
This issue is with only three servers in the environment
"Remote Desktop cannot verify the identity of the computer because there is a time or date diffrence between your computer and remote computer......"
The date/time is correct on the server when i checked in the console session of the server
Can see below messages in event logs
Event ID 1014:
"Name resolution for the name XYZdomain.com timed out after none of the configured DNS servers responded."
Event ID 1053:
The processing of Group Policy failed. Windows could not resolve the user name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).
Any thoughts ....

Hi,
Have you tried to connect these three servers with IP address instead of computer name or DNS name?
Check Remote Desktop Connection settings: Option-->Advanced-->Connect from anywhere-->Settings-->Connection Settings-->Select “Do not user an RD Gateway server”
For more information please refer to following MS articles:

Document access via WAN in portal

Hi,
I have the following problem. I have installed portal with KM in place A and some users are in place B. Both places are connected via WAN (1Mbit/s). Users in place B have some documents stored in there LAN so they can access them relatively quickly. But they would like to use functionality of KM. When I move their documents to the portal they will access these files over WAN connection. Is there some alternative solution? (users can navigate to the document via portal but than they download them from LAN). Can this be solved by WebDAV or Web repository manager?
Thanks a lot,
Zdenek

Hi Praskah,
thanks for help but I would like to avoid network traffic between two WAN locations. Imagine that you have 10MB file on network A on some WebDAV server for example that is in network A too. Portal resides in network B which is conntected with network A via 1mbit/s connection. Webdav repository is connected to this portal. I suppose that if you want to download your document from portal you must firstly transfer it from network A to network B (to the portal) and then from network B to network A again (to your desktop).
My question is: Can I avoid described useless network traffic and download document directly from network A?

I want to create serial communicatios between two notebooks via Bluetooth

Hi,
I'm trying to accomplish serial communications between two laptops via a Bluetooth connection.
The two laptops are NOT Toshiba notebook, but they are both running the Toshiba Bluetooth Stack For Windows. They are also both using the default Bluetooth Manager program that is supplied by Toshiba and Dell (just rebadged?).
Basically I can set up a connection no problems, but then I send serial data from one computer and watch the receiving serial port on the other computer but nothing ever arrives.
Are there any good tutorials for this? It would be nice to have something for the Toshiba Bluetooth Manager in particular as the windows and buttons will have the names as explained in the tutorial.
Thanks in advance.
Adam

I tried it for tests purpose via a hyperterminal connection and it worked.
Maybe the description contains also some helpful information for you.
Here is it:
PC1:
Start "Bluetooth Settings->Custom Mode->Select Remote PC->Select 'Serial Port'->Accept proposed COM port (in my case COM40)->Confirm wizard windows
until setup is finished".
PC2:
Start "HyperTerminal->Select COM7"
PC1:
Start "HyperTerminal->Select COM40 (in my case. See step 1 above)"
PC1, PC2:
Enter the same Passkey if security is turned on e.g. "0000"
PC1:
Everything what you type into HyperTerminal should be visible in HyperTerminal of PC2 and vice versa.

When transferring HR data from ECC to CRM via change pointers

When transferring HR data from ECC to CRM via change pointers ,certain data is getting earsed in CRM
paricularly the last name and first name of BUT000
Do you have any idea why this could be happening
Thanks in advance

Hi Kittu,
Change pointers. Change pointers are R/3 objects that mark changes to SAP master data. Change pointers are managed by mechanisms in a Shared Master Data (SMD) tool and are based on Change Document (CD) objects. CD objects record the changes occurring to master data at a field level. These changes are stored in tables CDHDR (header table) and CDPOS (detail table). ALE configuration provides a link between CD objects and change pointers. Internal mechanisms update tables BDCP and BDCPS, which host the change pointers. While CD objects are application-data-specific, the processing status of change pointers is message-type-specific. Also, the ALE change pointers are activated first at a general level and then at the message-type level.
use this links kittu.

What is defference between updating Firmware via P...

I'm N85 user and I want to know What is defference between updating Firmware via PC an Via Device manager on phone?

Firmware updates are usually released via one method or the other, rarely via both.
The NSU method downloads entire ROM images from Nokia's servers, resulting in downloads of more than 100MB in some cases.
The FOTA method only downloads what has changed from the version running on your phone to the latest version available. This means much less data to download, usually around 4-6 megabytes, which is important if you don't have access to a wireless network and have to use your operator's packet data service.
The FOTA method is safer (because it doesn't involve a computer running a notoriously flaky operating system) and faster (because there's less data to download).
Otherwise, the end result is the same.

Need charting help - multiple data points between major ticks

Hi,
I am trying to create an AreaChart in which the data shows a
consumption rate over the course of a week. The major points along
the x-axis will be Monday, Tuesday, ... , Sunday (the days of the
week). However, there are multiple data points between each day. I
only want the days of the week to show on the axis but I want to
plot all of the data points. How would I go about accomplishing
this task?

Many thanks for any advice.

You don't need conversion programs, iTunes can copy most of your content over to the iPad via the file sharing section, and some apps also support Dropbox, email attachments, transfer via your wifi network. There are a number of apps that you can get that support Microsoft office file (microsoft don't make an app versions of their software) e.g. from Apple there are Pages (word support), Numbers (excel) and Keynote (powerpoint), and from third-parties there are apps such as Documents To Go and QuickOffice HD

Difference between Clustering and Load balancing

          What is the difference between Clustering and Load balancing?
          For example, We use Cisco Arrowpoint to do load balancing and it works fine for 3
          Sun solaris boxes/WebLogic 6.1 SP1.
          So what is the value addition to buy clustering license?
          Thanks
          Selvaraj


Hi.
          Among other things, clustering allows you to share app data (such as http session
          data) across cluster members, allowing you to failover should one cluster member
          crash.
          If your app is stateless then this doesn't mean much - load balancing alone would
          probably be ok for you.
          Regards,
          Michael

What are differences between clustering and partitioning?

Thank you for reading my post
Can some one let me know what is different between clustering and partitioning?
What i think is as follow:
In clustering we have one storage (one hard disk for example) and several instances which use that storage to server the applications
in partitioning, we have multiple instances and each of them has its own storage (hard disk) but all of these instances and hard disks serve one application.

The word "cluster" has different meanings in Oracle.
Another kind of cluster is a database object where
master and detail rows are stored together in the
same block. Table joins are very efficient, but
reading data from one table and not another tends to
take longer. These kinds of clusters are vary rarely
used.Do not forget single table sorted hash cluster!

Wat is the exact differences between clustered table and pooled table

hi,
can you tell me ravi...wat is the exact differences between clustered table and pooled table
with regards//
anilreddyg

Hi Anil Reddy
Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
Table Pools
From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
Field Type Description
TABNAME CHAR(10) Table name
VARKEY CHAR(n) Maximum key length n =< 110
DATALN INT2(5) Length of the VARDATA record returned
VARDATA RAW(m) Maximum length of the data varies according to DBMS
Table Clusters
Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
Field Type Description
CLKEY1 CHAR(*) First key fields
CLKEY2 CHAR(*) Second key field
CLKEYN CHAR(*) nth key field
PAGENO INT2(5) Number of the next page
TIMESTMP CHAR(14) Time stamp
PAGELG INT2(5) Length of the VARDATA record returned
VARDATA RAW(*) Maximum length of the data section; varies according to database system
Working with Tables
The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
select Dictionary object Display from the menu.
In this screen, you can see table information such as
¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
¨ Short text description.
¨ Name of the user who made the last change, and the date of the change.
¨ Master language.
¨ Table status. On the screen, you can see this table is saved and active.
¨ Development class. For information on development classes, refer to Chap. 6.
Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
¨ Field name.
¨ Key indicator. When set, this field is the primary key, or part of it.
¨ Data element.
¨ Basic data type.
¨ Length.
¨ Check table.
¨ Short text, describing the field.
Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
Standard table:
The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
You should usually access a standard table with index operations.
Sorted table:
The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
Hash table:
The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
Index table:
The table can be a standard table or a sorted table.
Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.

In Icloud on my imac I can't see my "numbers" icon which i need to select "tick" to transfer data to my other devices via icloud. any ideas why it's not showing up?

You have to do it app wise, which means that the icon won't show up in settings, but you will be able to move files from your local drive to iCloud via the Numbers app (move... > choose the iCloud option).
It requires that you set up the same iCloud account on all your devices and that you have the latest version of Numbers on all your devices as well.
