SAP IQ is a decision-support server specifically designed to support mission-critical business intelligence, analytics, and data warehousing. SAP IQ is an effective column-based database management system specializing in Data Warehouse. It’s highly available, cost-effective, and optimized for business intelligence, data warehousing, and data marts. This software system was developed by Sybase Inc., and is now owned by SAP. It can analyze large amounts of data quickly and effectively for businesses requiring complex analytics.
SAP IQ 15.4 is a legacy version of the columnar database management system. It was widely used by many companies for its efficient handling of large datasets and high-speed processing capabilities. The system is known for its ability to handle complex queries and analytics while minimizing data storage requirements.
“However, as newer versions of the software have been released, it is encouraged to consider upgrading to take advantage of the latest features and improvements. ”
1.Upgrading to SAP IQ 16.1 is a necessity as legacy versions like 15.4 will no longer be supported by SAP for any bug fixes or patch releases.
2.The latest version offers several new features, including better performance, enhanced security, and improved user experience, making it a smart choice for companies looking to stay ahead of the curve.
3.As per the security policy of most organizations, the host operating system must be compliant against security vulnerabilities and undergo version upgrades.
4.The older version does not support incremental backup, which can be very challenging and unreasonable as the database size grows beyond 10TB. This can drastically reduce the performance and availability of the DB server.
5.The new software version of 16.0 or 16.1 introduces n-bit columnar FP indexes, providing a better compression ratio than byte columnar FP indexes, which further improves query response time and reduces storage space.
6.Companies that stick with the older version risk may face issues such as outdated security measures, lack of updates, and compatibility issues with other software.
7.Upgrading to the new version can help companies streamline their operations, improve their security, and provide updated features that keep them competitive in a fast-paced business environment.
Our upgrade strategy involved creating a new 16.1 environment and restoring and simultaneously upgrading from 15.4 to 16.1. To ensure a smooth transition, we created a parallel environment, backed up the data from 15.4, and restored it in 16.1. We then released the system for testing for 1 to 2 months, allowing the application team to note all necessary changes from the database and capture all priority tables and stored procedures.
This minimized the downtime by two days and allowed for a seamless migration from the old legacy database to the newly restored SAP IQ 16.1 database. Our expert team ensured that the entire process was executed seamlessly, and our clients could enjoy the benefits of the latest version without any interruptions.
Upgrading your SAP IQ from version 15.4 to version 16.1 can present some challenges, especially when it comes to the AIX platform. AIX is a simultaneous multi-threading system, which means specific parameters like shared memory are required during the upgrade process.
