PT XL Axiata Tbk, a leading telecommunications company in Indonesia, provides pre- and postpaid voice, SMS, and broadband internet packages, and a variety of add-on services, including access to social networking sites, ringtone options, and interactive games.
Over the last 15 years, PT XL Axiata Tbk has grown from a small company offering basic telephony services to the country’s second-largest telecommunications company in market share. It has an extensive network infrastructure and services, covering more than 90% of the population across Indonesia.
In November 2011, PT XL Axiata Tbk upgraded to four SPARC Enterprise M9000 and SPARC Enterprise M5000 servers to improve the storage capacity, performance, and reliability of its hardware infrastructure and to support an SAP enterprise resource planning and business intelligence application upgrade. The company reduced its maximum central processing unit (CPU) load by more than 40%, cut its dialog transaction response time by up to 50%, and increased its enterprise resource planning (ERP) and business intelligence transactions from 8,000 to 9,000 per week.
PT XL Axiata Tbk has also saved up to 50% on maintenance costs for its development, testing, and disaster recovery systems, using Oracle Solaris 10 virtualization.
PT XL Axiata Tbk has grown significantly in the past 15 years. It has 45 million cell phone and internet subscribers and more than 22,000 base transceiver stations across Indonesia. As the company grew, the amount of data about its telecommunications products and customers also increased. By 2011, the company held 3.5 TB of data about customers and products in its Oracle Database 11g.
PT XL Axiata Tbk uses SAP applications to manage ERP processes, such as financial reporting, purchasing, and asset management, and to perform business intelligence. Previously, the company was running its ERP and business intelligence applications and Oracle Database on three Sun Fire servers: two production servers and one development and testing server. It did not have a disaster recovery server. These servers had reached end of life and could no longer provide the required storage capacity or system performance. The number of users had also grown to between 1,300 and 1,400, which slowed down system response times.
“We needed to upgrade our server infrastructure to support our business growth, improve system performance and transaction speeds, and support our ERP and business intelligence application upgrade,” said Doni Setyawan, manager—IT ERP technical services, PT XL Axiata Tbk. “We also needed to complete the server migration in a limited timeframe with a minimum amount of downtime.”
PT XL Axiata Tbk has consolidated its Oracle Database and SAP applications on SPARC Enterprise M9000 servers.
By upgrading its production server to SPARC Enterprise M9000, PT XL Axiata Tbk has improved hardware capacity by reducing the queue by more than 40% for ERP and business intelligence processes that are using or waiting to use the CPU—including the queue for entering customer order details.
The company can now complete dialog steps needed to get from one screen to the next in its ERP and business intelligence applications up to 50% faster.
“The SPARC Enterprise M9000 server has cut our maximum CPU load from more than 70% to less than 30%, eliminating bottlenecks that affected system performance,” said Setyawan. “This has helped lower dialog transaction response times from more than 2,000 milliseconds to between 1,000 and 1,500 milliseconds.”
PT XL Axiata Tbk has also reduced its maximum CPU utilization rates by up to 50%.
“With our legacy Sun Fire server, CPU utilization rates could reach from between 90% to 100%,” said Setyawan. “With the new SPARC Enterprise M9000 server the maximum rate is 50%, which means our ERP and business intelligence applications will continue to perform well as the company grows and the amount of data we hold about customers and telecommunication products increases over the next three years.”
Improving system performance by lowering the CPU load and utilization rates enabled PT XL Axiata Tbk to increase the number of ERP and business intelligence transactions the company completes from 8,000 to 9,000 per week. The server can also generate ERP and business intelligence reports about customers’ broadband and internet usage, for example, about 50% faster.
“We have improved CPU processing power, the speed at which we can access data, and our application performance,” said Setyawan. “This has improved customer service and staff satisfaction, and enables senior managers to make quicker decisions, for example about which telecommunications product our next marketing campaign should focus on.”
PT XL Axiata Tbk runs its ERP and business intelligence applications on Oracle Solaris 10. The company also uses Oracle Solaris Containers to save up to 50% on maintenance costs for its development, testing, and disaster recovery systems.
“In the past, we didn’t have a disaster recovery system; however Oracle Solaris Containers allows us to safely and securely dedicate one server box to three different tasks, rather than using separate servers,” said Setyawan. “The virtualized infrastructure has also optimized system performance and load balancing, helping us to failover to our disaster recovery server in less than an hour in the event of an emergency. This means we can continue providing high-quality services to our customers in an emergency by enabling staff to still access ERP and business intelligence applications.”
The SPARC Enterprise M9000 and SPARC Enterprise M5000 servers have enabled PT XL Axiata Tbk to increase its system availability from between 98% and 99% to 99.95%, meeting its service level agreements.
“We have significantly reduced downtime by developing a reliable disaster recovery system and taking advantage of the hot-swappable power supplies, fans, and I/O cards, and the increased memory,” said Setyawan.
The server upgrade and subsequent reorganization of information has also reduced the amount of data in the company’s Oracle Database 11g from 3.5 TB to 2.6 TB.
Oracle was the first choice for PT XL Axiata Tbk’s server upgrade, and the company didn’t consider any other vendors.
“We needed reliable servers with greater storage capacity and faster performance, and Oracle SPARC servers best met those requirements,” said Setyawan. “In addition, Oracle has a proven track record for excellent customer service and a reputation for providing safe, reliable, and scalable servers for SAP customers.”
PT XL Axiata Tbk was also attracted to Oracle Solaris 10. “We could immediately see how the virtualized infrastructure would simplify our IT maintenance and administration, and were aware that Oracle Solaris 10 is also very compatible with SAP,” said Setyawan.
To ensure the company met the needs of its telecommunications customers, PT XL Axiata needed to complete the server migration in a limited timeframe with a minimum amount of downtime.
The company migrated its ERP and business intelligence applications onto the new servers in just three days. The entire migration took one week, with minimal downtime.
The SPARC Enterprise M9000 and SPARC Enterprise M5000 servers went live in November 2011.
PT XL Axiata Tbk engaged Oracle Specialized Partner PT Astra Graphia Information Technology (AGIT) to help implement the new SPARC servers.
“AGIT first prepared the servers at its site, then it delivered them to us at our data center in Cibitung,” said Setyawan. “From there, we handled the project management, including the hardware installation.
“AGIT delivered the servers on schedule and to specifications, and we were really happy with the team’s services,” he said.
