• Oracle Unveils Oracle Java Embedded Suite 7.0

  - by user12612705

  Today Oracle announced the Oracle Java Embedded Suite 7.0. What is the Java Embedded Suite (JES)? It's a middleware stack designed to be run on embedded devices. It's a suite which includes an application server (Glassfish for Embedded Suite), database (Java DB), and web services (Jersey Web Services Framework). Putting these services on the embedded device gives you the ability to provide a set of services at the device point. It also lets you aggregate data at the device point, which you can later sync with your enterprise systems.

• What is the benefit of not using Hungarian notation?

  - by user29981

  One of the things I struggle with is not using Hungarian notation. I don't want to have to go to the variable definition just to see what type it is. When a project gets extensive, it's nice to be able to look at a variable prefixed by 'bool' and know that it's looking for true/false instead of a 0/1 value. I also do a lot of work in SQL Server. I prefix my stored procedures with 'sp' and my tables with 'tbl', not to mention all of my variables in the database respectively. I see everywhere that nobody really wants to use Hungarian notation, to the point where they avoid it. My question is, what is the benefit of not using Hungarian notation, and why does the majority of developers avoid it like the plague?

• BIT of a Problem

  The BIT data type is an awkward fit for a SQL database. It doesn't have just two values, and it can do unexpected things in expressions. What is worse, it is a flag rather than a predicate, and so its overuse, along with bit masks, is a prime candidate for being listed as a 'SQL Code Smell'. Joe Celko makes the case.

• How do I Export to excel on aspx page?

  - by meltdownmonk

  I am trying to take data that I request from an access database and put it into and excel file on the client computer. I usually use ajax to request a summary of the data I need. It is formatted into an html table. I need that table to be in an excel format for the user to download. What I have tried already is to use the vb.net code to open excel and silently save the data to a file, however I realized it's the sever side that opens excel, not the client side, in my locally testing of the code, excel would open on my machine and create the file. When running this on the network, I realized excel isn't on the server, I am not sure if I should just install it, or try and steam the file.

• Problem on application with asp in IIS 7.5 with oracle 11g

  - by Hichem

  We have an application developed with .Net on server 2008 R2 and IIS 7.5 wich is linked liked to oracle 11g on another server. Our problem is that we lose the service every two or three or more. The application stops and we have to restart IIS or the server to continue the job (the number of users is less then 50). We have no error message. Do you know anything to do to avoid this situation, something like: A parameter to put on asp pages A parameter to switch on or off on the server or on the database

• Hybrid Columnar Compression

  - by user12620172

  You heard me in the past talk about the HCC feature for Oracle databases. Hybrid Columnar Compression is a fantastic, built-in, free feature of Oracle 11Gr2. One used to need an Exadata to make use of it. However, last October, Oracle opened it up and now allows it to work on ANY Oracle DB server running 11Gr2, as long as the storage behind it is a ZFSSA for DNFS, or an Axiom for FC. If you're not sure why this is so cool or what HCC can do for your Oracle database, please check out this presentation. In it, Art will explain HCC, show you what it does, and give you a great idea why it's such a game-changer for those holding lots of historical DB data. Did I mention it's free?

• Configuring trace file size and number in WebCenter Content 11g

  - by Kyle Hatlestad

  Lately I've been doing a lot of debugging using the System Output tracing in WebCenter Content 11g.  This is built-in tracing in the content server which provides a great level of detail on what's happening under the hood.  You can access the settings as well as a view of the tracing by going to Administration -> System Audit Information.  From here, you can select the tracing sections to include.  Some of my personal favorites are searchquery,  systemdatabase, userstorage, and indexer.  Usually I'm trying to find out some information regarding a search, database query, or user information.  Besides debugging, it's also very helpful for performance tuning.

• Advanced searching in Tracker Search Tool? Filter by folders?

  - by UrkoM

  Hi, I have checked several "Tracker Search Tool" questions, but they all stop at very superficial usage. Google, at least for me, didn't turn out anything either. Here is my situation: I have a lot of documents, and I want to index them all, and do fulltext searching on them. I have organized them by folders in advance, and sometimes I want to search across all subfolders, sometimes only in a specific subfolders. Is there any way to do it? Right now, I am changing the locations in the search preferences and triggering a hard-reset of the Tracker database, but that's far from ideal. I am using Maverick, 10.10.

• Is it possible to work with a dedicated server in XNA?

  - by Jake

  Hi I want to release my XNA game to the XBOX platform, but I'm worried about the networking limitations. Basically, I want to have a dedicated (authoritative) server, but it sounds like that is not possible. Which is why I'm wondering about: Using port 80 web calls to php-driven database Using an xbox as a master-server (is that possible?) I like the sound of #1, because I could write my own application to run on the xbox, and I would assume other users could connect to it similar to the p2p architecture. Anyone able to expand on theory #2 above? or #1 as worst-case scenario?

• Stairway to T-SQL DML Level 4: The Mathematics of SQL: Part 1

  A relational database contains tables that relate to each other by key values. When querying data from these related tables you may choose to select data from a single table or many tables. If you select data from many tables, you normally join those tables together using specified join criteria. The concepts of selecting data from tables and joining tables together is all about managing and manipulating sets of data. In Level 4 of this Stairway we will explore the concepts of set theory and mathematical operators to join, merge, and return data from multiple SQL Server tables. Get Smart with SQL Backup Pro Powerful centralised management, encryption and more.SQL Backup Pro was the smartest kid at school Discover why.

• Removing unnecessary joomla CMS components

  - by Gaz_Edge

  Background I have been developing a web application. I have been using Joomla platform and CMS as the base from my application. My application relies heavily on the joomla platform, but uses very few features of the CMS (I have to login users etc so I use the _users component of the CMS). Question What is the best way to start removing some of the excess CMS that I don't need? For example when I being building my production site, I will want to avoid creating a load of joomla component database tables etc. I have read that an application can be build from the ground up using just the joomla platform, but i still want to include the _users component and would also like to avoid having to start coding all the session handling aspects. Any advice?

• ClearTrace Supports SQL Server 2008 R2

  - by Bill Graziano

  It was a long time coming and I hope worth the wait.  If you have SQL Server 2008 R2 installed on the same box as ClearTrace and you download the latest ClearTrace build (36) you’ll be able to read SQL Server 2008 R2 traces.  I also fixed a bug handling very, very large SQL statements.  I encountered an INSERT statement that was 12MB in size.  It was storing XML in a database.  ClearTrace uses regular expressions to clean up the SQL it finds.  Running two dozen regular expressions over this 12MB string caused the application to crash.  In this build I’m just skipping any statement over 1MB.  I’ll do something a little nicer in the next build. (And if you don’t want to download ClearTrace you can test the online version at www.TraceTune.com)

• Who created that user?

  - by AaronBertrand

  Twitter has provided some great fodder for blog content lately. And twice this week, I've found an excuse to take advantage of the default trace. Tonight @meltondba asked: I'm trying to find who created a user act in a DB It is true, SQL Server doesn't really keep track of who created objects, such as user accounts in a database. You can get some of this information from the default trace, though, since it tracks EventClass 109 (Audit Add DB User). If you run this code: USE [master] ; GO CREATE LOGIN...(read more)

• /dev/sda1 100% Mysql to blame?

  - by SJP

  I have a an API running that receives raw binaries, processes them, and then stores metadata about the bins in a mysql database. I have been running it for a couple days on a VM. Today the API stopped processing the mySQL commands. After using the command df-h the results were: root@mwdb1:/# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 104G 99G 0 100% / udev 16G 4.0K 16G 1% /dev tmpfs 6.3G 364K 6.3G 1% /run none 5.0M 0 5.0M 0% /run/lock none 16G 0 16G 0% /run/shm /dev/sdb1 5.5T 42G 5.2T 1% /data sda1 is at 100%

• What does backup procedures and troubleshooting guidelines mean for a system

  - by Podolski

  I am writing the documentation for a piece of software which I have made but I don't understand what it means in some aspects. It asks me to write about backup procedures but what exactly does this mean? Does this mean like backing up the database on another hosting service or something else entirely? I am dumbfounded by what troubleshooting guidelines are as well. If you have any idea what this could mean feel free to give your insight even if you aren't 100% sure in case it could spark what it means inside of me. Thanks.

• Is there a program to manage movies and TV shows that supports mp4 tags?

  - by root45

  I'm looking for a media manager that will display and play movies and TV shows and will read data included in mp4 and m4v files. So far I've looked at XBMC, Moovida and Boxee and all of these seem to keep their own separate database or XML files for reading and storing tag information. I also looked at Banshee because of this answer, but it didn't read my tags. Banshee is also geared towards music videos instead of actual movies and TV shows. So I'm looking for software that Displays and plays movies and TV Shows Reads mp4 and m4v tags Preferably something with bulk import (i.e., I don't want to add 1,000 items to a new library) Bonus if it also has a tag editor Bonus if it's an XBMC extension

• multitenancy with some data sharing

  - by user55108

  I'm in the planning stages of a new webapp, and I am leaning strongly toward a multitenancy model. The app has a file storage function, where the user can upload (and operate on) files. I would like the ability of the user to share these files, however. How is this typically accomplished in a multi-tenant model? The example would be something like google docs. Each user has their own files; they can edit and tag and build collections with these files. Then, they can share a doc or a collection with someone else for collaboration. If every user has their own Database and tables, what strategy would one use to allow this kind of sharing while minimizing duplication of files and associated metadata?

• SQL Server Migration Assistant 2008 (SSMA)

  One of my client’s requirements is to migrate and consolidate his company departments’ databases to SQL Server 2008. As I know the environment, they are using MySQL , MS-Access and SQL Server with different applications. Now the company has decided to have a single dedicated SQL Server 2008 database server to host all the applications. So there are a few things to do to upgrade and migrate from MySQL and MS-Access to SQL Server 2008. For the migration task, I found the SQL Server Migration Assistant 2008 (SSMA 2008) is very useful which reduces the effort and risk of migration. So in this tip, I will do an overview of SSMA 2008.

• How can I set up private, per-user sections on Joomla?

  - by Michael Paulukonis

  For this weekend's GiveCamp project, my team has been tasked with adding some functionality to an existing Joomla-powered website for a non-profit. A certain type of user will login, and have access to a personal area where they can upload files, check for messages, see tasks that have been assigned, etc. Each user would have their own area. They would not be creating pages, and their information would only be visible to themselves (or a site-administrator, of course. No sort of weird HIPAA privacy involved). None of us have worked with Joomla before, but we'd like to help this non-profit. We're not sure if we're searching using the wrong terms, or if we're just not finding it. Is such a solution possible in Joomla? And/or are we better off building some standalone solution that interfaces with the same mySQL database as Joomla?
