Clustering and EBJ proxies...

          Reading through Weblogic docs, smart stubs handle most of the logic
          for load balancing and fail-over. Does this mean that those stubs have
          to be regenerated whenever a cluster configuration is changed? Does
          ejbc have to be run on every EJB?
          Thank's in advance

3 minutes!!! How can we decrease this setting???

Is Distributed Transaction Coordinator services of the application role are required by SQL Server 2012 for clustering and support of SharePoint 2013.

All I want to know is if Distributed Transaction Coordinator services of the application role are required by SQL Server 2012 for clustering and support of SharePoint 2013.
I have been planning and deploying my companies first Windows Server 2012/SQL Server 2012 Always On cluster and Always On Availability Groups Multi-Subnet cluster and instances for SharePoint 2013, and I will be brutally honest, the documentation on either
the MSDN and TechNet leave alot to be desired. Continually finding links in the documentation will take me from a Windows 2012 reference to a page talking about Windows Server 2008 or R2, The differences of which there are so many when it comes to configurations,
settings, roles, services when working with SQL Server 2012. I have been confused, frustrated, screaming mad, with all the misdirection in this documentation. The documentation takes me windows 2008 R2 which is different than 2012!
Tired and trying to pick myself up off the floor!

In general, DTC is not required for SQL 2012. But, since you are asking specifically about SharePoint, it would be better to ask in a SharePoint forum. They would be more likely to know those situations where FTC might be needed by SharePoint.

Array of clusters and in the cluster is a bar meter, how can I change the color individually?

Array of clusters and in the cluster is a bar meter, how can I change the color of the bar meter individually for each element of the array? I have just figured out that you can't change properties of one element of the array without all elements changing. For the scaling I had to make numeric indicators for each tick of the scale so that each bar meter in the clustered array would have individual scales. I also had to do some math to scale each barmeter to display correct proportions from 0 to 100%. Now I'm stumped on the color of the bar meter. Basically, if the value goes over a setpoint, the bar meter needs to turn red. It has to be in an array to be infinitely scalable.
Thanks
Matt
Solved!
Go to Solution.

You can't do that-
without a little trick.
You could consider laying a custom color box over the bar graph in the cluster you can set the color based on the value of the bar graph or even make a "Pseudo"- bar graph using a series of color boxes stacked to look lie a bar and changing values of the Color boxs from empty to full to red.
Here is an example to demonstrate

Proxies: are interfaces which will get executed in the application system.They can be created only in the system from message interfaces using the proxy generation functions.
The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.
The Proxy currently has the following components available:
1. ABAP Proxy Communication using XI or Web Services
2. Java Proxy Communication using XI (J2EE)

Abap proxies ( Client and Server proxies)

Hi Team
Good day to you. I am now started doing some example scenarios on ABAP proxies(ie Client and Server proxies). After going through the blogs which are avialable, i am writing this question to you for clarification.
As per my understanding, the below are the required predefined settings which i need to do in my landscape to generate abap proxies(ie client and server proxies).
My landscape includes the below systems.
System A : SAP XI 3.0 system and
System B : SAP R/3 on WAS 620
SAP R/3 predefined Steps
1.Create HTTP connection in the business system.
2.Configuration Business system as local Integration Engine.
3. Connection between Business System and System Landscape Directory.
4. Maintaining the SAP J2EE Connection Parameters for LCRSAPRFC and SAPSLDAPI in SAP J2EE engine
(Here in the step 4, i found the below needs to be done)
1. Goto J2EE Engine
2. Choose Cluster --> Server --> Services. JCo RFC provider
3. Under RFC destination specify the following:
     Program ID: LCRSAPRFC
     Gateway Host: <Integration Server host>
     Gateway Service: <Integration Server gateway service>
     Number of process: 3
4. Under Repository specify the following:
5. Choose Set.
Application Server: <Integration Server host>
(i am not able to perform the steps which comes under point 4. so please Guide me how to goto J2EE engine and configure accordingly.
5. Maintain SLD access details in Transaction SLDAPICUST.
As per my understanding, i need to do the above predefined configuration steps in SAP R/3 system (ie bussiness System) for doing Abap Client or Server proxies.
And in the meantime, i would like to know whether i need to do any predefined configuration steps in XI 3.o system also. Please check and suggest me accordingly.
Once i get clarification on predefined configuration steps, i will proceed with the example scenarios on client and server proxies which are already in SDN.
Thanks in advance.
Regards
Raj

Hello Pavan
thanks for your response. you said that for the connection type 'H' we need to provide values for GATEWAY HOST and GATEWAY SERVICE but here i need to create the RFC destination of type 'T'. so please tell me whether i need to give the values for GATEWAY HOST and GATEWAY SERVICE for connection type 'T' also and the second thing is please tell me the difference between Application system and bussiness system accordingly to my landscape which i mentioned in my question.
I am in little confusion because as per the requirement for abap proxies in the blog they mentioned that all these setting should be done in the bussiness system (ie SAP R/3) but you are saying that Application system. so please clarify.
My landscape which i am going to use in Abap proxy generation
System A: XI 3.0
System B: R/3
Here which is bussiness system and which is application system. Pls calrify.
Thanks in advance.

Raj

Maxdb new features - Page Clustering and Prefetch

Hi to all,
2 new features of maxdb are available with new patches: Page Clustering and Prefetch in OLTP-Systems.
Are there any experiences to this features?
READAHEAD_TABLE_THRESHOLD
"This parameter is used to specify, if read operations of tables
should be optimized, i.e. if during a table access more than the
specified value in pages is affected, servertasks will be used to
read ahead pages of this table."
I activated this parameter in November. The system now starts more quickly and some expensive sql-statements may be faster. But the average db-time didn't change.
Page Clustering can be activated with parameter: DATA_IO_BLOCK_COUNT
Then tables can be migrated with SQL-Statement: ALTER TABLE <table name> CLUSTER
I activated this only for one table. This table now is read much faster.
My questions.
Is there a documentation available for this features?
How can I "uncluster" clustered tables?
When this features are activated, expensive sql-statements are processed much faster. Because of the high workload on storagesystem, all other transaction may get slower?
regards
Franz

> 2 new features of maxdb are available with new patches: Page Clustering and Prefetch in OLTP-Systems.
First of all: both features, although technically available, are not yet generally released for OLTP usage.
The current implementation of page prefetching is explicitely a proof-of-concept implementation which should be used by recommendation from MaxDB support only.
There are several limitations to the functionality at the moment, e.g. it does only work for table scans.
It does not work for joins, for index builds neither does it work on clustered tables.
Prefetching is available to 7.6 release only at the moment, so after an upgrade to 7.7 this feature would be gone...
> I activated this parameter in November. The system now starts more quickly and some expensive sql-statements may be faster. But the average db-time didn't change.
Well, nothing surprising here.
On SAP start there happen a lot of tablescans, mostly attributable to the fully buffered tables for the ABAP internals (security, ddic, etc.)
These statements will of course benefit if the pages are now read into the buffer in parallel.
For the avg. db-time: be happy!
This basically means, that most of the statements running in your system aren't processed by table scans, which is for MaxDB nearly always a very good thing.
> Page Clustering can be activated with parameter: DATA_IO_BLOCK_COUNT
> Then tables can be migrated with SQL-Statement: ALTER TABLE <table name> CLUSTER
Ok, page clustering is not documented yet (just as prefetching is not officially documented) and not released for OLTP.
> I activated this only for one table. This table now is read much faster.
>
> My questions.
> Is there a documentation available for this features?
Hmm.. you're using undocumented features - what do you expect?`
No, currently there is no official documentation.
There is work going on to provide official documentation but none of it is released yet (and it will take some more time!)
> How can I "uncluster" clustered tables?
ALTER TABLE <tablename> NOT CLUSTER
> When this features are activated, expensive sql-statements are processed much faster. Because of the high workload on storagesystem, all other transaction may get slower?
It's not that simple.
Both features address specific issues and are used only in very specific circumstances.
The clustering feature will not improve performance if the table is not accessed via the cluster key.
In fact, it may even decrease performance if this is done.
Also, at the moment clustered tables don't stay clustered on updates/inserts/deletes.
Therefore it is not necessarily a good idea to cluster tables like REPOLOAD pr REPOSRC on a development system.

Lars

How to create and configure proxies in ADF mobile using OWSM client agent?

Hi
Can anyone please tell me how to create and configure proxies in ADF mobile application using Oracle Web Services Manager (OWSM) Lite Mobile ADF Application Agent. I read it in mobile document that,
For secured web services, the user credentials are dynamically injected using ADF Mobile uses Oracle Web Services Manager (OWSM) Lite Mobile ADF Application Agent to create and configure proxies, as well as to request services through the proxies. The user credentials are injected into the OWSM enforcement context when proxies are configured.
I am new with this OWSM, can anyone please give me some hints like how to proceed further for implementing authentication using OWSM lite mobile ADF Application Agent??
Thanks in advance
Raj

Hi Juan
The demo is very useful, and in that Shay describes about the remote login using a regular ADF webapplication as a secured one and deploying it into the server. But I would like to know how to create a local login using OWSM client agent? .
Without creating a regular ADF webapplication, how can i call secured webservices(i.e., by using OWSM client agent how to create and configure proxies to call secured webservice, where the user credentials are injected into webservice request by OWSM client as mentioned in ADF mobile document)??

Clustering and CF9 Standard?

Hi,
I have a couple of questions that I was hoping to get answered around ColdFusion 9 and clustering. Currently, we run CF8 and IIS on the same box with a dedicated db server and serve up about 10 applications. We are starting to look at clustering and I wanted to know:
1. With CF 9 Standard, can we setup clustering? Our apps have session vars and we want to use sticky sessions but I'm unsure if we can do that just with CF9 Standard.
2. Does CF play well with VMware? If so, does anyone have any success stories around Virtualizing CF?
Thanks,

1. No, you can not set up clustering in CF Standard. You could set up multiple servers and let a load balancer handle the distributio of requests over the servers, but then you do not have session failover. This may meet your requirements. Or not.
2. It works just fine. I can't remember when I set up CF for the last time on a non VMware system.

Clustering and partioning

Hi,
Can anyone please say What is the difference between clustering and partioning?.
What is mean by Hash Partioning ? I know it is done by hash value.How we will get the hash value?
Bit confusing to do self- study. It would be great if someone explains to me.
Thanks

Hi,
Clusters are two or more tables that are physically stored together to take advantage of similar columns between the tables. If two tables have an identical column and you frequently need to join the two tables, for example, it is advantageous to store the common column values in the same data
block. The goal is to reduce disk I/O and thereby increase access speed when you join related tables.
However, clusters will reduce the performance of your INSERT statements, because more blocks are needed to store the data of multiple tables.
Oracle partitions addresses the key problem of supporting very large tables and indexes by allowing you to decompose them into smaller and more manageable pieces called partitions.
Once partitions are defined, SQL statements can access and manipulate the partitions rather than entire tables or indexes.
Partitions are especially useful in data warehouse applications, which commonly store and analyze large amounts of historical data
Hash partitioning is a partitioning technique where a hash key is used to distribute rows evenly across the different partitions (sub-tables). This is typically used where ranges aren't appropriate, i.e. employee number, productID, etc.

Clustering and Partitioning

Hello SDN Friends,
Can both clustering and partioning possible together.

Hi,
Clustering is only supported by the database platform DB2 for Linux, UNIX, and Windows.
You can use partitioning to improve the performance of other databases.

Plz help me about clustering and loadbalancing

hi all
plz help me about clustering and loadbalancing
how to do clustering and loadbalancing in tomcat ?

I used Grid Bag Layout for allignment of all buttons and textfields.Use multiple different nested layout managers to get the desired layout.
Give it another try.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.

Linux clusters and oracle

This contradicts the information in the Oracle® Database Release Notes 10g Release 2 (10.2) for Linux x86-64:
In Oracle Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide, Chapter 2, "Preinstallation," in the section "Oracle Clusterware Home Directory," it incorrectly lists the path /u01/app/oracle/product/crs as a possible Oracle Clusterware home (or CRS home) path. This is incorrect. A default Oracle base path is /u01/app/oracle, and the Oracle Clusterware home must never be a subdirectory of the Oracle base directory.
A possible CRS home directory is in a path outside of the Oracle base directory. for example, if the Oracle base directory is u01/app/oracle, then the CRS home can be an option similar to one of the following:
u01/crs/
/u01/crs/oracle/product/10/crs
/crs/home
This issue is tracked with Oracle bug 5843155.
