Blocking row navigation in af:table , synchronize row selection with model in case of validation failure- Oracle ADF by Ashish Awasthi

- by JuergenKress

In ADF we often work on editable af:table and when we use af:table to insert ,update or delete data, it is normal to use some validation but problem is when some validation failure occurs on page (in af:table) ,still we can select another row and it shows as currently selected Row this is a bit confusing for user as Row Selection of af:table is not synchronized with model or binding layer See Problem- i have an editable table on page Read the complete article here.

Creating an email notification system based on polling database rows

- by Ashish Sharma

I have to design an email notification system based on the following requirements: The email notifications would be created based on polling rows in a Mysql 5.5 DB table when they are in a particular 'Completed' state. The email notification should be sent out in no more than 5 minutes from the time the row was created in the DB table (At the time of DB table row creation the state of the row might not be 'Completed'). Once 5 minutes for the DB table row expire in reaching the 'Completed' state, separate email notification need to be sent (basically telling the user that the original email notification would be delayed) and then sending the email notification as and when the row state reaches to being 'Completed'. The rest of the system requirements are : Adding relevant checks to monitor the whole system via MBeans interface. The system should be scalable so that if the rate of DB table rows creation increases so does the Email notification system be able to ramp up. So I request suggestions on following lines: What approach should I take in solving the problem described from a programming/Design pattern point of view? Suggestion for any third party plugin/software that can be used to solve the problem described? Points to take care regarding scalability and monitoring the health of the system? Java is the language of preference but I am open to using off the shelf components that can be interfaced with Java language or provide standard ports for communication. Currently I do have an in house grown system (written in Java) that is catering to the specified requirements, but it's now crumbling under increased load and now I want to give the problem a fresh look. thanks in advance Ashish

Determine whether a link points to a file on local host or foreign domain [migrated]

- by user107157

This has been a burning question for me ever since and I think it's interesting enough to discuss it on the forums. As most will know, in websites we include anchor links, stylesheets, script files (javascript) and images. For anchor links we use the form <a href="..." /> For stylesheets we may use the form <link rel="stylesheet" type="text/css" href="..." /> For javascript we may use <script src="..." /> For images we use <img src="..." /> So, the question is this: How do we know that what is in the link pointer (i.e. replacing the ... in each example) is a local file or a foreign entity? To make it clear, lets say I create a local file named "ashish.com". Now, my purpose is to create a link so that anybody who clicks on it may download it. So, my code would be thus: <a href="ashish.com">Download It</a> But this makes it ambiguous. I could also be referring to a website named "ashish.com" So, how does the computer magically know which one I mean? Or does it even know this? What would happen in such a scenario?

Delphi, Csv,Import Firebird

- by Vijesh V.Nair

Lemme explain my problem. I have One ID and 2 Other Fields in a CsV file. the ID connected to a database table. I have to show the curresponding entries in the db and fields from Csv. Need sort the Fields too. My Idea was load into a ClientDataset, lookup to a Query with table and Use sort and show. My Csv have 85 K Records and its taking 120 seconds to load and sort, Its not acceptable. Can you tell me, can I use Bacthmove for this. So I can easily pick fields by a simple query. if I can use Bacthmove Plz give me the guild lines. Also Is there any other Techniques for this? Thanks and Regards, Vijesh V.Nair

Hello, I had a Linux centos(5.5) machine, on this i had deployed amavisd (with clamav and spamassassin). Referred these: http://wiki.centos.org/HowTos/Amavisd http://wiki.centos.org/PackageManagement/Yum/Priorities Now I have a linux RHEL machine, details are as follows: (Linux version 2.6.18-164.6.1.el5 ([email protected]) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) x86_64 GNU/Linux Red Hat Enterprise Linux Server release 5.5 (Tikanga)) I want to set up the above mentioned software's on this(RHEL) machine, for that I do (as per the reference link): install yum-priorities but i am unable to install this on my said machine, because the default yum repository provided by RHEL doesn't contain this. How can i deploy the above software's on my RHEL machine, suggest any safe alternate. Please guide since i am a newbie in this matter. thanks in advance Ashish Sharma

Validate a string in a table in SQL Server - CLR function or T-SQL

- by Ashish Gupta

I need to check If a column value (string) in SQL server table starts with a small letter and can only contain '_', '-', numbers and alphabets. I know I can use a SQL server CLR function for that. However, I am trying to implement that validation using a scalar UDF and could make very little here...I can use 'NOT LIKE', but I am not sure how to make sure I validate the string irrespective of the order of characters or in other words write a pattern in SQL for this. Am I better off using a SQL CLR function? Any help will be appreciated.. Thanks in advance Thank you everyone for their comments. This morning, I chose to go CLR function way. For the purpose of what I was trying to achieve, I created one CLR function which does the validation of an input string and have that called from a SQL UDF and It works well. Just to measure the performance of t-SQL UDF using SQL CLR function vs t- SQL UDF, I created a SQL CLR function which will just check if the input string contains only small letters, it should return true else false and have that called from a UDF (IsLowerCaseCLR). After that I also created a regular t-SQL UDF(IsLowerCaseTSQL) which does the same thing using the 'NOT LIKE'. Then I created a table (Person) with columns Name(varchar) and IsValid(bit) columns and populate that with names to test. Data :- 1000 records with 'Ashish' as value for Name column 1000 records with 'ashish' as value for Name column then I ran the following :- UPDATE Person Set IsValid=1 WHERE dbo.IsLowerCaseTSQL (Name) Above updated 1000 records (with Isvalid=1) and took less than a second. I deleted all the data in the table and repopulated the same with same data. Then updated the same table using Sql CLR UDF (with Isvalid=1) and this took 3 seconds! If update happens for 5000 records, regular UDF takes 0 seconds compared to CLR UDF which takes 16 seconds! I am very less knowledgeable on t-SQL regular expression or I could have tested my actual more complex validation criteria. But I just wanted to know, even I could have written that, would that have been faster than the SQL CLR function considering the example above. Are we using SQL CLR because we can implement we can implement lot richer logic which would have been difficult otherwise If we write in regular SQL. Sorry for this long post. I just want to know from the experts. Please feel free to ask if you could not understand anything here. Thank you again for your time.

ODI 12c's Mapping Designer - Combining Flow Based and Expression Based Mapping

- by Madhu Nair

post by David Allan ODI is renowned for its declarative designer and minimal expression based paradigm. The new ODI 12c release has extended this even further to provide an extended declarative mapping designer. The ODI 12c mapper is a fusion of ODI's new declarative designer with the familiar flow based designer while retaining ODI’s key differentiators of: Minimal expression based definition, The ability to incrementally design an interface and to extract/load data from any combination of sources, and most importantly Backed by ODI’s extensible knowledge module framework. The declarative nature of the product has been extended to include an extensible library of common components that can be used to easily build simple to complex data integration solutions. Big usability improvements through consistent interactions of components and concepts all constructed around the familiar knowledge module framework provide the utmost flexibility. Here is a little taster: So what is a mapping? A mapping comprises of a logical design and at least one physical design, it may have many. A mapping can have many targets, of any technology and can be arbitrarily complex. You can build reusable mappings and use them in other mappings or other reusable mappings. In the example below all of the information from an Oracle bonus table and a bonus file are joined with an Oracle employees table before being written to a target. Some things that are cool include the one-click expression cross referencing so you can easily see what's used where within the design. The logical design in a mapping describes what you want to accomplish (see the animated GIF here illustrating how the above mapping was designed) . The physical design lets you configure how it is to be accomplished. So you could have one logical design that is realized as an initial load in one physical design and as an incremental load in another. In the physical design below we can customize how the mapping is accomplished by picking Knowledge Modules, in ODI 12c you can pick multiple nodes (on logical or physical) and see common properties. This is useful as we can quickly compare property values across objects - below we can see knowledge modules settings on the access points between execution units side by side, in the example one table is retrieved via database links and the other is an external table. In the logical design I had selected an append mode for the integration type, so by default the IKM on the target will choose the most suitable/default IKM - which in this case is an in-built Oracle Insert IKM (see image below). This supports insert and select hints for the Oracle database (the ANSI SQL Insert IKM does not support these), so by default you will get direct path inserts with Oracle on this statement. In ODI 12c, the mapper is just that, a mapper. Design your mapping, write to multiple targets, the targets can be in the same data server, in different data servers or in totally different technologies - it does not matter. ODI 12c will derive and generate a plan that you can use or customize with knowledge modules. Some of the use cases which are greatly simplified include multiple heterogeneous targets, multi target inserts for Oracle and writing of XML. Let's switch it up now and look at a slightly different example to illustrate expression reuse. In ODI you can define reusable expressions using user functions. These can be reused across mappings and the implementations specialized per technology. So you can have common expressions across Oracle, SQL Server, Hive etc. shielding the design from the physical aspects of the generated language. Another way to reuse is within a mapping itself. In ODI 12c expressions can be defined and reused within a mapping. Rather than replicating the expression text in larger expressions you can decompose into smaller snippets, below you can see UNIT_TAX AMOUNT has been defined and is used in two downstream target columns - its used in the TOTAL_TAX_AMOUNT plus its used in the UNIT_TAX_AMOUNT (a recording of the calculation). You can see the columns that the expressions depend on (upstream) and the columns the expression is used in (downstream) highlighted within the mapper. Also multi selecting attributes is a convenient way to see what's being used where, below I have selected the TOTAL_TAX_AMOUNT in the target datastore and the UNIT_TAX_AMOUNT in UNIT_CALC. You can now see many expressions at once now and understand much more at the once time without needlessly clicking around and memorizing information. Our mantra during development was to keep it simple and make the tool more powerful and do even more for the user. The development team was a fusion of many teams from Oracle Warehouse Builder, Sunopsis and BEA Aqualogic, debating and perfecting the mapper in ODI 12c. This was quite a project from supporting the capabilities of ODI in 11g to building the flow based mapping tool to support the future. I hope this was a useful insight, there is so much more to come on this topic, this is just a preview of much more that you will see of the mapper in ODI 12c.

postfix Mail filters not running behind a controlled enviornment

- by Ashish

Hi, I have deployed a postfix server for email receiving. On this I have configured SenderID + SPF milter, by referring to http://www.postfix.org/MILTER_README.html The command that I used is as follows: ./sid-filter -u postfix -p inet:10027@localhost -l Following are my settings in main.cf file: #Milter support for smtpd mail smtpd_milters = inet:localhost:10027, inet:localhost:10028 # Milters for non-SMTP mail. non_smtpd_milters = inet:localhost:10027, inet:localhost:10028 milter_default_action = reject # Postfix . 2.6 #milter_protocol = 6 # 2.3 . Postfix . 2.5 milter_protocol = 2 Now I have this observation: One of the postfix that is setup on AWS CentOS 5.5 is working fine and is able to receive mails on defined mx record. One of the similar postfix(as in step 1) that is setup behind one of the corporate firewalls is not able to receive any mails and is giving following type of error logs: connect from xxxxxx.austin.hp.com[xx.xxx.96.198] May 25 13:20:02 g2t0385g postfix/smtpd[11733]: C11F9B0194: client=xxxxxxx.austin.hp.com[15.217.96.198] May 25 13:20:03 g2t0385g postfix/cleanup[11814]: C11F9B0194: message-id= May 25 13:20:03 g2t0385g postfix/cleanup[11814]: C11F9B0194: milter-reject: END-OF-MESSAGE from xxxxxx.austin.hp.com[xx.xxx.96.198]: 5.7.1 Command rejected; from= to= proto=ESMTP helo= Here the 'sid-filter' is giving problems.

A design pattern for data binding an object (with subclasses) to asp.net user control

- by Rohith Nair

I have an abstract class called Address and I am deriving three classes ; HomeAddress, Work Address, NextOfKin address. My idea is to bind this to a usercontrol and based on the type of Address it should bind properly to the ASP.NET user control. My idea is the user control doesn't know which address it is going to present and based on the type it will parse accordingly. How can I design such a setup, based on the fact that, the user control can take any type of address and bind accordingly. I know of one method like :- Declare class objects for all the three types (Home,Work,NextOfKin). Declare an enum to hold these types and based on the type of this enum passed to user control, instantiate the appropriate object based on setter injection. As a part of my generic design, I just created a class structure like this :- I know I am missing a lot of pieces in design. Can anybody give me an idea of how to approach this in proper way.

Big Data Matters with ODI12c

- by Madhu Nair

contributed by Mike Eisterer On October 17th, 2013, Oracle announced the release of Oracle Data Integrator 12c (ODI12c). This release signifies improvements to Oracle’s Data Integration portfolio of solutions, particularly Big Data integration. Why Big Data = Big Business Organizations are gaining greater insights and actionability through increased storage, processing and analytical benefits offered by Big Data solutions. New technologies and frameworks like HDFS, NoSQL, Hive and MapReduce support these benefits now. As further data is collected, analytical requirements increase and the complexity of managing transformations and aggregations of data compounds and organizations are in need for scalable Data Integration solutions. ODI12c provides enterprise solutions for the movement, translation and transformation of information and data heterogeneously and in Big Data Environments through: The ability for existing ODI and SQL developers to leverage new Big Data technologies. A metadata focused approach for cataloging, defining and reusing Big Data technologies, mappings and process executions. Integration between many heterogeneous environments and technologies such as HDFS and Hive. Generation of Hive Query Language. Working with Big Data using Knowledge Modules ODI12c provides developers with the ability to define sources and targets and visually develop mappings to effect the movement and transformation of data. As the mappings are created, ODI12c leverages a rich library of prebuilt integrations, known as Knowledge Modules (KMs). These KMs are contextual to the technologies and platforms to be integrated. Steps and actions needed to manage the data integration are pre-built and configured within the KMs. The Oracle Data Integrator Application Adapter for Hadoop provides a series of KMs, specifically designed to integrate with Big Data Technologies. The Big Data KMs include: Check Knowledge Module Reverse Engineer Knowledge Module Hive Transform Knowledge Module Hive Control Append Knowledge Module File to Hive (LOAD DATA) Knowledge Module File-Hive to Oracle (OLH-OSCH) Knowledge Module Nothing to beat an Example: To demonstrate the use of the KMs which are part of the ODI Application Adapter for Hadoop, a mapping may be defined to move data between files and Hive targets. The mapping is defined by dragging the source and target into the mapping, performing the attribute (column) mapping (see Figure 1) and then selecting the KM which will govern the process. In this mapping example, movie data is being moved from an HDFS source into a Hive table. Some of the attributes, such as “CUSTID to custid”, have been mapped over. Figure 1 Defining the Mapping Before the proper KM can be assigned to define the technology for the mapping, it needs to be added to the ODI project. The Big Data KMs have been made available to the project through the KM import process. Generally, this is done prior to defining the mapping.

This is done by selecting the Physical View of the mapping and examining the Properties of the Target. In this case MOVIAPP_LOG_STAGE is the target of our mapping. Figure 4 Physical View of the Mapping and Assigning the Big Data Knowledge Module to the Target Alternative KMs may have been selected as well, providing flexibility and abstracting the logical mapping from the physical implementation. Our mapping may be applied to other technologies as well. The mapping is now complete and is ready to run. We will see more in a future blog about running a mapping to load Hive. To complete the quick ODI for Big Data Overview, let us take a closer look at what the IKM File to Hive is doing for us. ODI provides differentiated capabilities by defining the process and steps which normally would have to be manually developed, tested and implemented into the KM. As shown in figure 5, the KM is preparing the Hive session, managing the Hive tables, performing the initial load from HDFS and then performing the insert into Hive. HDFS and Hive options are selected graphically, as shown in the properties in Figure 4. Figure 5 Process and Steps Managed by the KM What’s Next Big Data being the shape shifting business challenge it is is fast evolving into the deciding factor between market leaders and others. Now that an introduction to ODI and Big Data has been provided, look for additional blogs coming soon using the Knowledge Modules which make up the Oracle Data Integrator Application Adapter for Hadoop: Importing Big Data Metadata into ODI, Testing Data Stores and Loading Hive Targets Generating Transformations using Hive Query language Loading Oracle from Hadoop Sources For more information now, please visit the Oracle Data Integrator Application Adapter for Hadoop web site, http://www.oracle.com/us/products/middleware/data-integration/hadoop/overview/index.html Do not forget to tune in to the ODI12c Executive Launch webcast on the 12th to hear more about ODI12c and GG12c.
