Distributed Storage Framework

Hello!
I know that this is not the right forum to post the question, but I don't know where to post it.
I'm working on a project to partitioned a large table inside a database. We have looked for many database frameworks like Sequoia:
http://sequoia.continuent.org/HomePage
and many other similar projects.
Is there anybody that knows a Java based tool to partitioned large tables?
I have also seen MS SQL server, but we don't want to lock the solution to a database vendor.
Best regards

Use third party framework in Command Line Tool

Hi. I'm writing a small application for a friend of mine, and basically what it does is lets you put in some information, and then creates and stores that information in an Excel file. However, all of my research suggests that C++ doesn't work nicely with Excel files, so I found a 3rd party framework called LibXL which provides C++ with the ability to create and edit Excel files. My only problem is getting my Command Line Tool to use this framework. I'm not even sure if it is possible, but if someone could help me out, I would really appreciate it!
P.S: I'm using XCode 4.2 to write this application, and I'm using Command Line Tool because the application has to be useable on Windows.

That last one is an excellent punch line!
>I found a 3rd party framework called LibXL which provides C++ with the ability to create and edit Excel files.
That should be coming with a manual. Some frameworks can be included in their entirety into the program you are writing, where for others you can only reference to it and you have to distribute the framework file(s) along with your own application. This doesn't sound like one, but an external framework may only be meant for GUI functions, in which case you cannot write a Terminal-only program.
But here comes the kicker:
>P.S: I'm using XCode 4.2 to write this application, and I'm using Command Line Tool because the application has to be useable on Windows.
It's possible for you to *write* the program but not to compile it. (Actually, you *can* compile it but then you have a Mac Terminal program, not a Windows one.) Even if you know what you are doing and are happy with sending over the source code, together with instructions on how to compile it under Windows, this implies you would only and *exclusively* use functions that are available in compilers for Windows. That rules out your External framework idea -- unless there is a Windows version available as well (do check for that; if this is an Open Source project, there very well may be.) But you are still programming "blind", and if you get it to work on your Mac (and nevermind the problem with the framework being external, because you won't need to send it over anyway) but your friend canNOT make it work under Windows, you won't know if it's because the Windows version of the compiler doesn't accept the external library, or it's the wrong version, or you accidentally used a Mac-only feature anyway, or the friend does not know how to compile ... et cetera, et cetera.
Best advise is to install VirtualBox (or something similar) on your system, test all you want with XCode but then, after you got it to work, carry over the project into Windows and start a-new.

Licensing Framework

Hello,
does anyone know where one can find a freely distributed licensing framework, or suggest any solution to unblock certain functionalities only for the users provided with a licence? (talking of experimental software that I developed, not minded for commerce at present status) .

Hello Yassine,
What license do we have to take if we want to use only this provider ?
You will need a SQL Anywhere client license (a "seat") for each of your client deployments. You may want to talk to SAP Sales for further details about your exact requirements for your planned deployments.
What are the limitation of this provider (Sybase database version comptatibility, EF6 limitations ?)
See further details about EF6 support here:
http://sqlanywhere-forum.sap.com/questions/22161/entity-framework-6-provider
EF6 support was first released with CR #768717, in SQL Anywhere 12.0.1.4142 and 16.0.1993. There was an additional fix required for the design-first wizard in CR #770760 in 12.0.1.4162 and 16.0.2014.
Finally, there was an issue with Microsoft EFTools 6.1.1 and lower where the third-party provider would not be detected correctly until the project included the assembly reference in the app.config file and the project was built. In EFTools 6.1.2 and higher, only the app.config reference is required - building the project or cleaning the project should not affect this issue now.
Is there support regarding this provider ?
Yes, any issues with the provider can be reported as an incident to SQL Anywhere SAP Support via the component BC-SYB-SQA. You can also post issues to here or on our alternative forum: http://sqlanywhere-forum.sap.com/
Where can i find differences between v12 and v16 ?
The official documentation ( http://dcx.sap.com/ ) lists the changes between version 12.0.0 and 16.0:

Licensing Framework for Java

Hello,
does anyone know where one can find a freely distributed licensing framework for java applications, or suggest any solution to unblock certain functionalities only for the users provided with a licence? (talking of experimental software that I developed, not minded for commerce at present status) .

there are some java libraries that are free for non
commercial use but require to purchase a license for
commercial applications.yes there is. This is true also of non java software.
There is also the GPL (GNU public license) which allows you to distribute the code, but only in an open source way.
My question is : what if some one use this library in
commercial app without purchasing licence ? how can
the owner of the librairy control the use of his
work. and if you use it for commercial purposes what
will happen ?Then you have a lawsuit. The damaged party may seek compensation and potentially damages from the license violator. The license owner may also seek an injunction

What is the diffrence between a javabean and EJB

hi!
what is the diffrence between a javabean and entreprise jvaabeans! i mean which are the uitilization featires of eaxh one !

i am seeking for a solution for my problem , in fact i ma trying to implement and develop an application with java that allows a certain range of IP adresses to be connected to a database server in order to extract the suitable data from the server .
let me explain mor ethe suitation , in fact what i am loking for is to use javabeans to grant my application much more consistence and pertinence : si i am asking if it could be possible to use javabeans in my case especially if i am not trying to developp a web application but a cleint /server one allowing some services.
The application is in fact dealing with a stock exchange market and what i am trying to do is to grant particilar registrated customers to have the informations that they need ( portofolio, currency's status, market indicators, .) also drawing some charts decribing rates, variations, and others specefic financial caracterestics .So , if we consider that this application is not a web application ( no HTTP request and no servers like apache or others ) how it is possible to use javabeans and not EJB to build the application? i mean what could be suitable and preferable to rely on and dvelop to ensure a good java application !!
if you need more details to help you find the answer for me don't hesitate to answer me back !!
Someone here gave me that answer
use RMI to code the services and (Updateable) Value Objects to pass the information between tiers.
RMI is an all-java distributed component framework (ie. EJB, CORBA, DCE/RPC, DCOM, etc.), that is very suitable for developing non-containerized multi-tier applications. Refer to the RMI trail in the Java Tutorial as a starting point for coding RMI solutions (http://java.sun.com/docs/books/tutorial/index.html). Under this scenario you would code the database access service as an RMI service (server-side). Client/server communication should be facilitated through the use of JavaBeans/classes that wrap the information being passed (customer information, portfolio details, market information, etc.) - these are refered to as 'Updateable Value Objects' (a design pattern). Graphing and charting would be handled in your client from the information received from the (RMI) server. GUI JavaBeans can be used to provide this functionality as well as other client-side services. There are numerous "shrink-wrapped" components for GUIs available on the market just peruse any Java magazine to find them.
but how comes? how can i do it !! and where can i find more information please about 'Updateable Value Object "
thanks

ENTERPRIZE BACKUP UTILITY

제품 : ORACLE SERVER
작성날짜 : 1996-11-29
1. The Problem
과거 메인 프레임 환경에서 사용하던 고객들이 저 비용, C/S환경으로
Migration시에는 주로 Open system과 Oracle RDBMS를 채택하고 있다.
이런 관계로 해당 제품 시장은 고 성장을 구가하고 있기도 하다.
이러한 고 성장을 가능케 하는 요소는 물론 H/W,S/W에서의 혁신적인
진보이나, 메인 프레임급에 걸 맞는 대용량 DB를 관리하고 Backup하는
데 필수적인 System management tool은 과거와 크게 달라진 바가 없다.
tar, cpio, dd같은 UNIX backup tool들은 실제 backup media의 관리
측면에서 별 기여 를 하지 못하고 있다. 대용량 DB를 위한 Backup script는
source만 해도 수백line에 달하며 test와 troubleshoot에서도 많은 문제점을
갖고 있다. 뿐만 아니라 대용량 Database(이하 VLDB)의 Restore는
Backup보다도 훨씬 더 복잡한 문제를 갖고 있다.
최근의 Backup file이 어느 곳에 저장 되었는지를 알기 위해 Backup
tape을 분류하고, damaged file들을 restore 해야 하는 등의 일련의 작업이
필요하다.
2. The Solution
최근에 몇몇 media management vendor들은 media management기능,
scheduling기능, 강력한 security기능, UNIX system에서 제공하는 backup
tool이상의 신뢰성을 갖는 강력한backup product를 공급하기 시작했다.
이러한 product들은 system level에서의 관리를 용이하게 해주는 장점은
있으나 이미 위에서 지적된 VLDB의 backup시 제기되는 문제점들을
완전히 해결해 주지는 못한다.
Oracle7 Enterprise Backup Utility(이하 EBU)는 이런 문제점을 해결하는
solution이다. EBU는 backup/restore시 media management product와 강력한
인터페이스를 제공하며 다른 어느것과 비교 할 수 없는 강점을 갖고
있다.
3. Introducing Oracle7 Enterprise Backup Utility
EBU는 open system상에서 메인 프레임급 성능을 제공하여 한 기업
전반에 걸쳐 전략적으로 중요한 역할을 감당하게 된다. 이 utility는 DB의
신속한backup과 restore를 위해disk와 backup될 media device에서H/W
parallelism을 이용한다.open system의 full capacity를 이용하기 위해
device가 add될 때 performance가 증가된다.parallel H/W, backup
configuration check ,error detection and cleaning ,restore시의
database의block verification과 같은 특징들이EBU가 high reliability를 갖게
하는 특징들이다.
Oracle7 데이타베이스는 data files, control files, redo log files로
구성되는데 EBU는data file, control file을 backup받고 archived redo log
file을 받는다. (release2.0.8) Media failure의 경우 DB를 full restore/
partial restore가 가능하며 data file도 선택적으로 최근의 last backup까지,
어느 일정 시점 까지 만의 선택이 가능하다. 또한 recovery도 일정 시점으로
완전recovery가 가능하다.
4. Architecture
EBU는 크게 두 부분으로 구성되는데 backup하려 하는 DB에 관한 모든
current정보와history를 관리하는 catalog부분, 그리고 실행 파일 부분으로
구성된다. 실행 파일들과 catalog는 반드시 같은 host내에 존재할 필요는
없다. 실행 파일들은 다음으로 구성된다.
*obackup : 모든 다른 프로세스들을 monitor하며 backup하려하는 DB,
catalog와의 communication을 담당한다.또한 Instance Manager를
running시킨다.
*brio : obackup, brdk, brtp사이 조정 역할을 수행한다.parallel I/O
stream당 하나의 brio process가 발생한다.
*brdk : Disk file의 read/write를 조절한다. File당 하나의 brdk를 발생시키
므로 만일 여러 개의 file들을 하나의 single data stream으로 결합시
키는 경우 하나의 I/O stream내에 여러 개의 brdk process를
create한다.
*brtp : Tape file들의 read/write를 조절한다. I/O stream당 하나의 brtp
create.
*brd : Instance Manager로써 backup catalog, obackup을 monitor하는
daemon process이다. backup을 위한 cleanup과 비정상 종료된 작업을
복구 한다.
Backup동안 database file들은 disk process인 brdk에 의해 읽혀져 backup
buffer area로 넘겨지고 그 후 third vendor의 media management s/w를
경유하여 backup device에 brtp process에 의해 write된다. Restore시는
반대의 과정이 진행된다. 위의backup buffer는 hard disk와 tape device간에
발생하는 I/O상의 speed mismatch를 조절하는 역할을 한다.
5. EBU의 장점(Benefits)
Third vendor의 media management product와 함께 사용되는 EBU는
기존의 UNIX 에서 제공하는 backup tool보다 다음과 같은 강력한 장점을
지닌다.
(1) 강력한 Reliability.
*. Consistent backup procedures
기존의 hot backup script의 경우 만일 datafile이 추가될 경우 script에
새로 지정해 주어야 하며 VLDB의 경우 script만 해도 수백line에 달하여
관리상 번거로운 게 사실 이였다. 그러나 EBU의 경우는 어느 datafile이
어느directory에 위치하는지를 작업자가 알 필요가 없고 script는 짧고
단순하여 누구든 쉽게 알아볼 수 있다.
또한 DB 구성이 자동으로 확인되며 backup media를 자동으로 인식 및
관리한다.
예).full online backup script .partial online backup script
backup online database backup online
db_name = "PRODB" db_name = "PRODB"
oracle_sid = "PROD" oracle_sid = "PROD"
tablespace = "SALES"
.full restore script
restore database
db_name = "PRODB"
oracle_sid = "PROD"
이와 같이 간단한 script에 의해 DBA는 VLDB를 쉽게 backup과 restore를
할 수 있으며 작업에 필요한 세부정보는 backup catalog내에 있게 된다.
*. End-to-End checksum
Backup시 EBU는 각 backup data의 byte를 계산하고, restore시도 계산하여
정상 수행 여부를 판단 시 checksum 값을 상호 체크 한다.
*. Instance Manager
Instance Manager는 backup/restore시에 진행 상황을 monitor하고 작업
중에 에러가 발생시 복구 및 각종resource를 release시키는 기능을 담당하게
한다.
(2) High Performance
다음과 같은 EBU의 특징과 고속media device의 지원 아래 VLDB의
backup을 적은시간 내에 완전하게 수행 할 수 있게 되었다.
*. Parallel Hardware Capability
Backup/restore시 multiple device를 사용하여 동시에 여러 tablespace에
대한 작업을 수행 할 수 있다. VLDB와 같이 다수의 tablespace, datafile이
여러 disk에 분산되어 있는 경우 이와 같이 물리적으로 다수의 device를
parallel하게 사용함으로서 performance를 극대화 시킬 수 있다.
Backup시 동시 사용되는 device의 수와 performance는 정비례하게 나타난다.
*. Multiplexing
EBU는 backup device가 최고의 속도로 backup을 수행 할 수 있게 script에
지정 할 수가 있다.이것은 backup media access속도보다 disk access
속도가 훨씬 작은 경우에 여러 disk에 분산된 datafile들을 한device에
multiplexing되게 지정함으로 가능하다.
*. Null Block Compression
EBU는 backup시 null data block을 skip시키고 restore시 재구성함으로써
공간 을 절약하며 performance를 증가시킨다.
*. Buffered I/O
EBU는 disk I/O와 device I/O사이의 access speed의 mismatch를 줄이기
위하여 모든 I/O stream을 bufferring한다. 양쪽의 I/O는 shared memory
buffer를 거치게 함으로써 backup/restore수행 중 항시 일정 속도를 유지
하게 한다. shared memory는 user가 parameter로 구성할 수 있으며 기본
적으로는 parallel data stream의 개수와 buffer size에 dependent하다.
(3) Availability
한 기업에서 전략적으로 중요한 DB들은 대부분 24시간*7일 full로
가동되며, 사용 중에 backup을 수행할 수 밖에 없다. Offline full backup은
당연히 지원되며, EBU는 DB를 online상태로 full backup이 가능하며,
또한partial backup도 가능하다. 기존의 online backup이 backup으로 인해
performance를 저하시키는 단점이 있었으나 EBU는DB 운영에 최소의
영향만을 미친다.
Recovery시에도 full로 restore 시킬 수 있으며 나머지는 사용 중인
상태에서 필요 부분만 partial restore가 가능하다. 일단 EBU가 data를
restore시킨 후에는 기존의 Oracle7의 표준 recovery process가 적용되어
진다.
(4) Usability
*. Auto-configuration
Online backup을 수행 시 EBU는 current DB configuration과 backup catalog
내의 가장 최근의 configuration정보를 비교하여 backup catalog정보가 더
오래 전의 것이면 EBU는 DB의 backup직전으로 update시킨다.
Auto-configuration은 default이며 명시적으로 지정하여 disable시킬 수 있다.
Offline backup시는 backup script내에 backup command기술 전에 register
라는 명령어를 기술 해야만 configuration정보를 update시킬 수 있다.
*. Light-Out backups
Third party의 media management s/w를 이용하여 EBU를 operator의 개입 없
이 자동으로 수행이 가능하다. UNIX의 cron에서도 자동으로 수행되게 할 수
있다.
*. Raw device support
EBU는 raw device로 잡힌 DB도 operator의 특별한 조치 없이 일반 file
system의 backup과 똑같이 수행할 수 있게 한다.
*. Aggregated restore
기업의 mission-critical system에서의 backup 전략들은 흔히 partial
backup에 의존하게 된다. 이와 같은 환경에서는 backup data내의 모든file에
대한 current version을 검색하는 일이 중요한데 EBU는 이것을 자동으로
수행한다. partial backup data는 restore시 media failure이전에 취해진
가장 최근의 full backup data와 aggregated 되어져 이용된다.
*. Point-in-Time restore
EBU는 backup catalog내에 backup하려하는 DB에 대한 모든 configuration
history를 갖고 있어서, 만일 하나의 tablespace가 drop된 후 다시 필요하게
되면 비록 그 후 일정 시간이 경과되고 많은 변경이 일어났더라도 drop직전으로
일부분만 restore하여 사용이 가능하게 할 수 있다. 이 같은 tablespace는
다른 machine에 restore 될 수도 있어 현재의 DB작동에 아무 영향을 미치지
않고 수행할 수가 있다.
*. Backup catalog
EBU에 의해 제공되는 backup catalog는 모든 backup대상 DB의 configuration
과 history의 저장소로써 제공된다. backup catalog에 저장된 정보는 backup된
file, tablespace 그리고 multiplexing정보, 마지막backup이나 restore의
시간기록,backup type(full or subset),backup들이 저장 되어 있는 file set
등을 포함하고 있다. 하나의 backup catalog는 기업 내 모든 분산된 dB들을 관리
할 수 있다.
*. Dry Runs
VLDB를 backup시 겪는 문제 중 하나는 과연 script가 정상적으로 수행이 완료
되는지를 검증하는 것이다. 특별한 방법이 없는 한 긴 시간 동안 수행시켜 끝난
후 확인 할 수 밖에 없는데 EBU는 I/O없이 간단히 test로 수행을 시킬 수가
있다. 이로 인해 신뢰성 있는 backup전략을 DBA가 수립 가능하게 한다.
*. Enterprise-wide backup
이것은 backup이 단순히 single database에 국한되지 않고 한 기업 전체에
걸쳐서 global하게 수행 가능함을 말한다. 예로 전국적으로 다수의 site에
database가 구축 되어진 상황에서 각database들이 two phase commit,
snapshot 같은 분산처리 작업을 통해 다른 database들을 synchronous하게
또는 asynchronous하게 update할 경우 기업 전체를 하나의 logical
database로 보고 이런 logical database를 중앙에서 EBU를 통해 backup시킬
수가 있다.EBU는 중앙의 catalog내에 모든database들에 대한 backup정보를
간직하고 있다.
이와 같은 중앙의 한 지점을 통하여 기업 전체 모든 database들에 대한
backup수행 기능은 EBU의 가장 큰 장점 중 하나이며 이런 경우 N/W상에 대량의
data가 전송되어 network의 bandwidth가 backup의 중요한 요소로 부각된다.
6. Flexibility
*. EBU API
EBU는 앞에서도 소개되었듯이 단독으로 사용되는 것이 아니고 third-part
에서 제공하는 media management product와 같이 사용된다. 이때 두 product
사이의 interface는 backup/restore Application Programming Interface
(API Glue)에 의해서 이루어 진다. 이것은 third part에 의해 제공되며
EBU install시 installer에 의해 자동적으로 access된다.
*. Media management products
Epoch*s EpochBackup, IBM Adstar*s Distributed Storage Manager,
Legato Systems*NetWorker, HP*s Omniback*, SprectraLogic*s
Alexandria,StorageTek*s REEL, etc.
*. Media device
4mm and 8mm DATS,3480s,3490s,WORM,Writable Optical Devices and
automated systems such as stackers and silos.
7. Pricing
EBU는 무상으로 공급되며 사용을 위해서는 third vendor의 media
management product를 구입하여 설치하여야 한다.

Sure, would you clarify which DB, which OS and which product?
Concept in general is quite simple:
- stop BOE (SIA on XI3, All services, finishing with CMS on XIr2, ideally putting a sleep between all servers shutdown and CMS shutdown). NET STOP on windows.
- Backup the CMS DB (imp/exp on Oracle, mysqldump for MySQL)
- Backup the FileStore (use robocopy in a batch for delta backup)
- Restart BOE
The "catches" are around Oracle doing export in US7ASCII by default under Unix, which is a destructive conversion from UTF8 (your CMS DB should be under this format as per supported platforms), so you need to make sure to set the NLS_LANG to UTF8 on Unix user doing the backup.
Other than that, batch as shell can do all of that.
Regarding the "general" best practices, I recommend the following doc:
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/c0020482-ca8d-2c10-9bad-d1bd332bbb28
Note on integrated BO tools: Import Wizard as biarengine are good tools for promoting a set of data between wto BOE environment or if you need to backup a specific set, but they are definitly not recommended as backup solution. I would refrain from this solution IF the point of the backup is to be able to recover the system when it crashes.
Does that answer the question?

OCFS2 vs. NFS

I am currently in the process of an evaluation. We are planning to run an OpenVZ Cluster (true hypervisors have too much latency/overhead for the required scenario) with a shared storage for all participating nodes.
The OpenVZ containers will be stored on the shared filesystem. Use case is mostly reads (executing one binary in each container, which may load bulk data into memory from the shared fs as well), practically no writes. Since every process will run in its own OpenVZ container directory, there will be no concurrent reads/writes (ie locking should not be much of an issue). There might be > 200 node clients, each node might have up to 20 openvz containers (though since these use the node FS this should not matter). We want to use a central and cheap storage (no distributed storage).
Since OpenVZ is RHEL based i am considering Oracle Linux (i assume the OpenVZ RHEL 6.x based Kernel will run without issues on Oracle Linux). Now considering the shared filesystem i could use NFS or OCFS2 on top of iSCSI (linux software based) over Ethernet. I read a few performance benchmarks, in which OCFS2 comes out on top due to a more scalable design. However i am not sure whether these benchmarks are all that relevant to my use case, since they take into account more "normal file system usage". NFS is a lot easier to setup and to maintain, however if OCFS2 performs and scales significantly better for my use case i would give it a try.
I would appreciate all input, since i assume there are quite a few people out there who are more knowledgeable with such use cases and OCFS2 in particular.

We are using OCFS on a 4 node RHEL cluster to store 100's of 1000's of files. Mostly small files (containing config data of h/w devices we poll). Around 600GB used in total.
A file listing (the ls command) is a bad idea in such directory.. but this is true of most any file system with such file volumes. ;-)
No performance issues reported by development. BTW, we are running it using IPoIB (IP over DDR/10Gb Infiniband - we still need to wire the QDR/40Gb IB switches and move the OCFS heartbeat/Interconnect to faster Infiniband).
And I disagree with the statement that it is more complex than NFS. It is very simple to configure and use.

DB type repository manager for information broadcasting?

I read some article which says only FSDB type of repository manager can be used for BI informaiton broadcasting. I want to broadcast to MOSS server, which uses IIS, but stores everything in database. Is there anyway to use DB or WSDL type repository manager for broadcasting?
Thanks
Jane Zhou

Where did you get this information from? Is there any document that states that? Below is the information I got, it says FSDB has to be used:
Can I use information broadcasting to distribute precalculated queries, Web applications, and workbooks to a third-party file server, Web server or document management systems?
Yes. With information broadcasting, you can precalculate queries, Web applications, and workbooks and publish them into the Knowledge Management of the SAP NetWeaver Portal.
In KM, you can easily create a Repository Manager (CM repository with persistence mode FSDB) that is attached to a file system directory (for example, the directory of an Internet Information Server (IIS)). You have to create a link in the KM folder of documents to the folder of the CM Repository attached to the file system or you can define your CM Repository as an entry point in KM. For more information, see SAP Note 827994 (SMP login required).
Information broadcasting can automatically put a new report on the third-party file server (for example, using the data change event in the process chain). KM offers repository managers for many different file servers, Web servers, and document management systems (such as IIS and Documentum):
1.                            Create CM Repository attached to file system.
2.                            Use iView KM Content to create subfolder in file system (optional).
3.                            Set permission to Administrator (optional).
4.                            Create link in /documents to folder of CM Repository attached to file system or define CM Repository as entry point. (See SAP Note 827994.)
5.                            Schedule Broadcasting Settings that export to a linked folder of CM Repository.
Because documents created via Information Broadcasting have additional attributes attached to them which mark them as broadcasted documents, it is not possible to store these kind of documents in a "pure" file system repository because such a repository usually only stores properties like "last changed", "creator", etc. Fortunately, KM provides a mechanism to nevertheless use a file system repository to store the documents. The additional properties will be stored in the database. Details are given here and here.
The "persistence mode" of the repository must be "FSDB" to allow this kind of behavior. Please note that because of the distributed storage of file and additional properties, the property assignment will be lost when moving around the document in the file system using some non-KM tool like windows explorer.

OSB result caching with Coherence Out of process

Existing setup:
Oracle Fusion Middleware SOA 11g domain with
1 weblogic cluster
1 OSB cluster
We have an Out of Process Coherence cluster configured with caches defined already which is just working fine in production.
The requirement is that development team would like to use the OSB result caching feature and we are having hard time to configure this OSB result cache join our existing cluster.
Any suggestions on this is appreciated.

Hi,
You would need to override the operational configuration on OSB Server to join the cluster spawned by the Coherence dedicated servers. Also, set the flag -Dtangosol.coherence.distributed.storage=false in the ServerStart of your OSB Servers which will disable the data storage in the OSB Servers.

Out-of-process Coherence server (OSB)

Hi,
Iam trying to set up a seperate coherence server , i.e not the default coherence cache supported with weblogic (Fusion middleware server).
I started the coherence server setup on seperate machine(jvm) and followed the steps to integrate the out-of process coherence server with OSB /weblogic server.
But the application deployed is still storing data to the deafult cahe provided by the OSB(weblogic) server.
Can any one help me with the steps to integrate OSB/Weblogic server with external Coherence/Cache server.
Thanks,

The "persistence mode" of the repository must be "FSDB" to allow this kind of behavior. Please note that because of the distributed storage of file and additional properties, the property assignment will be lost when moving around the document in the file system using some non-KM tool like windows explorer.

Can i use EJB with Swing?

Hi,
I am developing an application in which i am using the "Swing" for GUI.Can i use the "EJB" with swing?
regards

Hi,
Sure you can. The earlier poster has said the same thing too. Just that hes made out like this is possible only in jboss. EJB is a distributed component framework and can support multiple types of clients. The client can be a servlet or jsp, another EJB or in your case a swing application. In fact many IDE's allow you to test your EJB called by generating an application client. You need to add a special application client deployment descriptor file ( atleast with weblogic) in order to do this.
Hope this helps.
cheers,

It's not possible to state a blanket requirement for education. What education, training and certifications you will need for a job with Apple will depend on the particular job. The job description should state the education and experience they are looking for in a candidate. Look through the jobs in the appropriate category on Apple's employment site and you can get a feel for the type of education you will need to pursue if you're trying to plan your college course path.

Classpath Hlep

I have written a distributed object framework, using RMI to invoke remote processes and pass asynchronous messages between agents on disparate machines. I do this in order to solve NP-hard non-linear logistical planning problems.
Yet still I cannot get my classpath to work.
Please hlep.

Javapedia: Classpath
Setting the class path (Windows)
How Classes are Found
java -cp .;<any other directories or jars> YourClassNameYou get a NoClassDefFoundError message because the JVM (Java Virtual Machine) can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that you are in the same directory as the class you're trying to run.
javac -classpath .;<any additional jar files or directories> YourClassName.javaYou get a "cannot resolve symbol" message because the compiler can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that you are in the same directory as the class you're trying to run.

How can I make Terminal run Java 7 downloaded from the Oracle Website?

I've downloaded Java 7 from the Oracle website, and I want the Terminal application to run that Java 7 download. I try to run Java programs that require Java 7, but it runs with the Apple Internal Java 6 release. How can I make it so my MacBook Pro runs the download of Java that I downloaded? I know this sounds stupid, but am I routing my machine to run the internal Java 6 version? I have seen many videos in which people with the same software version as me run Java like this with no problem. Could you please let me know why this is happening and how I can fix it? I really want to be able to use the Java 7, particularly because I'm always getting this "Unsupported Major Minor Version 51.0" from many applications that are Terminal based.
Thanks!

I think I've answered your question. The Oracle JRE is a web plugin. The JDK is a development kit for applications with embedded Java. Neither one replaces the Apple-distributed Java frameworks for running standalone applications without embedded Java. Any other questions you have should be answered by the Oracle documentation.
