Drilling deeper into VSAM RLS with focus on performance

As discussed earlier, VSAM RLS that enables simultaneous access of VSAM files across multiple CICS region and batch (to a limited extent) is quite relevant today. To get good performance of VSAM RLS, it is necessary to understand better how it works and also the parameters that can be used for tuning. Continued »

Understanding VSAM RLS that provides limited sharing between CICS and batch

CICS applications are estimated to handle more than 30 billion transactions per day and process more than $1 trillion worth of business every week. VSAM is where the data is for a large percentage of these CICS application. It is also confirmed by the 2010 z/Journal CICS survey where 74% of the respondents found that CICS applications and batch having concurrent access to VSAM data as very important.

VSAM Record-level sharing (RLS) enables VSAM data to be shared, with full update capability, between many applications running in many CICS regions. Before RLS, sharing VSAM data between CICS regions typically meant allocating the VSAM to one CICS file-owning region (FOR) and function ship file requests from other CICS regions to the file-owning region using MRO or APPC connections.

iCloud enables “Every doc, every edit, everywhere”

Sasirekha R Profile: Sasirekha R

Apple’s iCloud has “Every doc, every edit, everywhere” as the Mantra

Apple unveiled its next generation software – Lion, the 8th major release of Mac OS X, version 5 of iOS that powers iPad, iPhone and iPod touch and the much touted new cloud service offering iCloud.  iCloud brings the cloud service to consumers and all of its features are aimed at making it “convenient and completely effortless’ for the users.

When you sign-up for iCloud, Apple provides 5 GB of cloud storage for free for user files. The purchased music, application, books and photos do not count against this free storage and so for individuals it is almost like having unlimited storage. With iCloud, the music you purchase in iTunes would appear automatically on all your devices (of course, from Apple!) – and no more sync required.  Even for your past purchases from iTunes, you can access your purchase history and download the ones you already bought to any of your devices.

DB2 version 10 – Extended Indicator Variables allows insert and update of subset of columns

Sasirekha R Profile: Sasirekha R

DB2 version 10 enables insert and update of subset of data enhancing reusability of DB2 functions

With the increase in the Web 2.0 applications, there are frequent situations where the application needs to insert or update data only for a subset of columns for a given table. And it becomes all the more difficult when it is not known which columns are being inserted to or updated until application execution time. For example, the customer address change request could mean changing the entire address or just the apartment number or any combination of columns (street name, city, zip code, apartment number and others).

Prior to DB2 version 10, the options for handling different combination of insert and updates included:

  • Using a dynamic SQL statement constructed at execution time for each request. Obviously this has overhead and impacts performance.
  • Coding SQL statements for all expected combinations of columns – and if we assume that every single combination is possible, the number of SQL statements to be coded grows exponentially. This indeed is a tedious process and has negative impact on application maintenance.
  • Have one SQL statement that included all the expected columns. While the customer request comes with data corresponding to only a subset of columns, it becomes the application’s responsibility to figure out the correct values for the other columns – say the old values in case of update, default values in case of insert and NULL values for nullable columns etc. Again, this makes application program complex – and testing difficult.

DB2 10 for z/OS addresses this difficulty of supporting changes to only a subset of columns in a table by introducing the extended indicator variable support. Preparing separate INSERT or UPDATE statements for every combination of columns that are being inserted is no longer required. Continued »

Websense Data Leak Prevention expected to gain more traction in Enterprises

Websense Data Leak Prevention expected to gain more traction in Enterprises

According to security experts, it costs organizations several million dollars per incident of data loss or theft. Even if the incident per se is innocent – like employee sending customer data to their personal emails so that they can work from home, the repercussions could be significant. In addition to direct loss in terms of money, any data leakage or loss results in negative publicity and putting the organization’s reputation at stake.

As reported by the Ponemon Institute, the average per-person expense for a data breach in 2010 was $214, with the average organizational cost at $7.2 million. The cost factors include detection, escalation, notification, response, and lost business feature. It is expected that this cost will continue to rise and especially so with the new regulations in almost all domains.

Content-aware data loss prevention (DLP) solutions enable organizations to enforce effective business practices for storing and transmitting sensitive data and avoid data loss / leakage. Continued »
