Essar Group needed to upgrade to Oracle Database 11g to improve the processing speed of enterprise resource planning (ERP) applications across its 2,000 diverse business units. The group also wanted to reduce database administration and storage costs, and gain automatic failover capabilities to protect against unnecessary system downtime.
Essar Group has been using Oracle Database since 1999 to store information—including inventory data from its steel manufacturing businesses—and the organization had many good reasons to continue using the database in the future.
“IT staff with Oracle Database 11g skills are widely available, more than specialists with skills in managing IBM DB2 or Sybase databases,” said Subhash Shelke, associate vice-president, SAP basis projects, Essar Group.
Initially, Essar Group discussed the benefits of upgrading to Oracle Database 11g with each vertical business within the group. The organization’s IT team then completed a proof of concept, which was verified and validated by the provider of its core applications to ensure the organization had applied all the relevant support packs and patches.
“Our IT team completed the upgrade in about nine hours for each Oracle instance, ensuring it was a smooth transition with minimal disruption to the organization,” said Shelke.
Oracle Database 11g went live in February 2011.
