Informatica announced yesterday the Informatica ILM Nearline product is SAP-certified. ILM Nearline helps IT organizations reduce costs of managing data growth in existing implementations of the SAP NetWeaver Business Warehouse (SAP NetWeaver BW) and SAP HANA. By doing so, customers can leverage freed budgets and resources to invest in its application landscape and data center modernization initiatives. Informatica ILM Nearline v6.1A for use with SAP NetWeaver BW and SAP HANA, available today, is purpose-built for SAP environments leveraging native SAP interfaces.
Data volumes are growing the fastest in data warehouse and reporting applications, yet a significant amount of it is rarely used or infrequently accessed. In deployments of SAP NetWeaver BW, standard SAP archiving can reduce the size of a production data warehouse database to help preserve its performance, but if users ever want to query or manipulate the archived data, the data needs to be loaded back into the production system disrupting data analytics processes and extending time to insight. The same holds true for SAP HANA.
To address this, ILM Nearline enables IT to migrate large volumes of largely inactive SAP NetWeaver BW or SAP HANA data from the production database or in memory store to online, secure, highly compressed, immutable files in a near-line system while maintaining end-user access. The result is a controlled environment running SAP NetWeaver BW or SAP HANA with predictable, ongoing hardware, software and maintenance costs. This helps ensure service-level agreements (SLAs) can be met while freeing up ongoing budget and resources so IT can focus on innovation.
Informatic ILM Nearline for use with SAP NetWeaver BW and SAP HANA has been certified with the following interfaces:
- NW-BW-NLS Nearline Storage SAP NetWeaver BW 7.30 on SAP HANA for Informatica Data Archive 6.1A
- NW-BW-NLS 7.30 – Nearline Storage – SAP NetWeaver BW 7.30 for Informatica Data Archive 6.1A
- BC-HCS 6.20 – HTTP Content Server 6.20 for Interface for Informatica Data Archive 6.1
“Informatica ILM Nearline for use with SAP NetWeaver BW and SAP HANA is all about reducing the costs of data while keeping the data easily accessible and thus valuable,” said Adam Wilson, general manager, ILM, Informatica. “As data volumes continue to soar, the solution is especially game-changing for organizations implementing SAP HANA as they can use the Informatica-enabled savings to help offset and control the costs of their SAP HANA licenses without disrupting the current SAP NetWeaver BW users’ access to the data.”
Specific advantages of Informatica ILM Nearline include:
- Industry-leading compression rates – Informatica ILM Nearline’s compression rates exceed standard database compression rates by a sizable margin. Customers typically achieve rates in excess of 90 percent, and some have reported rates as high as 98 percent.
- Easy administration and data access – No database administration is required for data archived by Informatica ILM Nearline. Data is accessible from the user’s standard SAP application screen without any IT interventions and is efficiently stored to simplify backup, restore and data replication processes.
- Limitless capacity – Highly scalable, the solution is designed to store limitless amounts of data without affecting data access performance.
- Easy storage tiering – As data is stored in a highly compressed format, the nearline archive can be easily migrated from one storage location to another in support of a tiered storage strategy.
Available now, Informatica ILM Nearline for use with SAP NetWeaver BW and SAP HANA is based on intellectual property acquired from Sand Technology in Q4 2011 and enhanced by Informatica.
 Informatica Survey Results, January 23, 2013 (citation from Enterprise Data Archive for Hybrid IT Webinar)
The Oracle Application User Group (OAUG) Archive and Purge Special Interest Group (SIG) held its semi-annual session first thing in the morning, Sunday September 22, 2013 – 8:00am. The chairman of the SIG, Brian Bent, must have lost in the drawing straws contest for session times. Regardless, attendance was incredibly strong and the topic, ‘Cleaning up your Oracle E-Business Suite Mess’, was well received.
From the initial audience survey, most attendees have made the jump to OEBS R12 and very few have implemented an Information Lifecycle Management (ILM) strategy. As organizations migrate to the latest version, the rate of data growth increases significantly such that performance takes a plunge, costs for infrastructure and storage spike, and DBAs are squeezed with trying to make due.
The bulk of the discussion was on what Oracle offers for purging Concurrent Programs. The focus was on system tables – not functional archive and purge routines, like General Ledger or Accounts Receivable. That will be a topic of another SIG day.
For starters, Oracle provides Concurrent Programs to purge administrative data. Look for ‘Big Tables’ owned by APPLSYS for more candidates and search for the biggest tables / indexes. Search for ‘PURGE’ on MyOracleSupport (MOS) – do your homework to decide if the Purge programs apply to you. If you are concerned about deleting data, you can create an archive table, add an ‘on delete’ trigger to the original table, run the purge and automatically save the data in the archive table (Guess what? This is a CUSTOMIZATION).
Some areas to look at include FND_Concurrent Requests and FND_LOBS.
- Most customers purge data older than 7-30 days
- Oracle recommends keeping this table under 25,000 rows
- Consider additional Purges that delete data about concurrent requests that run frequently
- DBAs do not delete from FND_LOBS; the only way to get rid of them is for Oracle to provide a concurrent Program for the module that users used to load them up
- Can take an enormous amount of space and make exporting and importing your database take a long time
- You can also look to store FND_LOBS as secure files, but requires advanced compression licenses
- Log enhancement requests for more concurrent programs to clean up FND_LOBS
- Look to third party solutions, such as Informatica
Other suggestions include WORKFLOW, but this requires more research.

In my last post, I discussed how our Informatica ILM Nearline allows vast amounts of detail data to be accessed at speeds that rival the performance of online systems, which in turn gives business analysts and application managers the power to assess and fine-tune important business initiatives on the basis of actual historical facts. We saw that the promise of Informatica ILM Nearline is basically to give you all the data you want, when and how you want it — without compromising the performance of existing data warehouse and business reporting systems.
Today, I want to consider what this capability means specifically for a business. What are the concrete benefits of implementing Informatica ILM Nearline? Here are a few of the most important ones.
Informatica ILM Nearline enables you to keep all your valuable data available for analysis.
Having more data accessible – more details, covering longer periods – enables a number of improvements in Business Intelligence processes:
- A clearer understanding of emerging trends in the business – what will go well in the future as well as what is now “going south”
- Better support for iterative analyses, enabling more intensive Business Performance Management (BPM)
- Better insight into customer behavior over the long term
- More precise target marketing, bringing a three- to five-fold improvement in campaign yield
Informatica ILM Nearline enables you to dramatically increase information storage and maintain service levels without increasing costs or administration requirements.
- Extremely high compression rates give the ability to store considerably more information in a given hardware configuration
- A substantially reduced data footprint means much faster data processing, enabling effective satisfaction of Service Level Agreements without extensive investments in processing power
- Minimal administration requirements bring reductions in resource costs, and ensure that valuable IT and business resources will not be diverted from important tasks just to manage and maintain the Informatica ILM Nearline implementation
- High data compression also substantially reduces the cost of maintaining a data center by reducing requirements for floor space, air conditioning and so on.
Informatica ILM Nearline simplifies and accelerates Disaster Recovery scenarios.
A reduced data footprint means more data can be moved across existing networks, making Informatica ILM Nearline an ideal infrastructure for implementing and securing an offsite backup process for massive amounts of data,
Informatica ILM Nearline keeps all detail data in an immutable form, available for delivery on request.
Having read-only detail data available on-demand enables quick response to audit requests, avoiding the possibility of costly penalties for non-compliance. Optional security packages can be used to control user access and data privacy.
Informatica ILM Nearline makes it easy to offload data from the online database before making final decisions about what is to be moved to an archiving solution.
The traditional archiving process typically involves extensive analysis of data usage patterns in order to determine what should be moved to relatively inaccessible archival storage. With an Informatica ILM Nearline solution, it’s a simple matter to move large amounts of data out of the online database — thereby improving performance and guaranteeing satisfaction of SLA’s, — while still keeping the data available for access when required. Data that is determined to be no longer used, but which still needs to be kept around to comply with data retention policies or regulations, can then be easily moved into an archiving solution.
Taken together, these benefits make a strong case for implementing an Informatica ILM Nearline solution when the data tsunami threatens to overwhelm the enterprise data warehouse. In future posts, I will be investigating each of these in more detail.
Data warehouses tend to grow very quickly because they integrate data from multiple sources and maintain years of historical data for analytics. A number of our customers have data warehouses in the hundreds of terabytes to petabytes range. Managing such a large amount of data becomes a challenge. How do you curb runaway costs in such an environment? Completing maintenance tasks within the prescribed window and ensuring acceptable performance are also big challenges.
We have provided best practices to archive aged data from data warehouses. Archiving data will keep the production data size at almost a constant level, reducing infrastructure and maintenance costs, while keeping performance up. At the same time, you can still access the archived data directly if you really need to from any reporting tool. Yet many are loath to move data out of their production system. This year, at Informatica World, we’re going to discuss another method of managing data growth without moving data out of the production data warehouse. I’m not going to tell you what this new method is, yet. You’ll have to come and learn more about it at my breakout session at Informatica World: What’s New from Informatica to Improve Data Warehouse Performance and Lower Costs.
I look forward to seeing all of you at Aria, Las Vegas next month. Also, I am especially excited to see our ILM customers at our second Product Advisory Council again this year.
Alternative Methods of Managing Data Growth and Best Practices for Using Them as Part of an Enterprise Information Lifecycle Management Strategy
Data, either manually created, or machine generated, tend to live on forever, because people hold on to it for fear that they might lose information by destroying data.
There is a saying in Bhagavad Gita:
jaathasya hi dhruvo mr.thyur dhr.uvam janma mr.thasya cha |
thasmaad aparihaarye’rthe’ na thvam sochithum-arhasi ||
“For death is certain to one who is born; to one who is dead, birth is certain; therefore, thou shalt not grieve for what is unavoidable.” (more…)
Both partitioning and archiving are alternative methods of improving database and application performance. Depending on a database administrator’s comfort level for one technology or method over another, either partitioning or archiving could be implemented to address performance issues due to data growth in production applications. But what are the best practices for utilizing one or the other method and how can they be used better together?
The need for more robust data retention management and enforcement is more than just good data management practice. It is a legal requirement for financial services organizations across the globe to comply with the myriad of local, federal, and international laws that mandate the retention of certain types of data for example:
- Dodd-Frank Act: Under Dodd-Frank, firms are required to maintain records for no less than five years.
- Basel Accord: The Basel guidelines call for the retention of risk and transaction data over a period of three to seven years. Noncompliance can result in significant fines and penalties.
- MiFiD II: Transactional data must also be stored in such a way that it meets new records retention requirements for such data (which must now be retained for up to five years) and easily retrieved, in context, to prove best execution.
- Bank Secrecy Act: All BSA records must be retained for a period of five years and must be filed or stored in such a way as to be accessible within a reasonable period of time.
- Payment Card Industry Data Security Standard (PCI): PCI requires card issuers and acquirers to retain an audit trail history for a period that is consistent with its effective use, as well as legal regulations. An audit history usually covers a period of at least one year, with a minimum of three months available on-line.
- Sarbanes-Oxley:Section 103 requires firms to prepare and maintain, for a period of not less than seven years, audit work papers and other information related to any audit report, in sufficient detail to support the conclusions reached and reported to external regulators.
Each of these laws have distinct data collection, analysis, and retention requirements that must be factored into existing information management practices. Unfortunately, existing data archiving methods including traditional database and tape backup methods lack the required capabilities to effectively enforce and automate data retention policies to comply with industry regulations. In addition, a number of internal and external challenges make it even more difficult for financial institutions to archive and retain required data due to the following trends: (more…)
In this video, Richard Cramer, chief healthcare strategist, and Claudia Chandra, senior director, product management, ILM, Informatica, discuss healthcare and application retirement.
During this discussion (the first of two videos), Richard and Claudia cover the following topics as they relate to healthcare:
- The business case for application retirement
- Additional drivers for application retirement
The second video, discusses application retirement project scope, enterprise IT initiatives and how application retirement is the fastest way for IT to save money now.
Just like your house needs yearly spring cleaning and you need to regularly throw out old junk, your application portfolio needs periodic review and rationalization to identify legacy, redundant applications that can be decommissioned to reduce bloat and save costs. If you have a hard time letting go of old stuff, it’s probably even harder for your application users to let go of access to their data. However, retiring applications doesn’t have to mean that you also lose the data within them. If the data within those applications are still needed for periodic reporting or for regulatory compliance, then there are still ways to retain the data without maintaining the application. (more…)
Gartner hosted a webinar on January 10, 2012: Gartner Worldwide IT Spending Forecast. One of the topics covered was industry IT spend for 2012.
In covering that topic they made a point of saying that due to severe flooding in Thailand, they expect storage to become in short supply (as much as a 29% global shortfall) through the end of 2012. It is expected that the price of storage/GB will increase as a result and supplies will fall short of demand. They recommended finding alternatives to purchasing storage to keep costs down. (more…)
