Even small database issues can impact banking for millions.
Itaú makes sure it doesn’t happen.

The largest bank in Latin America, Itaú Unibanco maintains its industry leadership with a customer-centric strategy. It continuously invests in technology, innovation, and accessibility to enhance the digital experience and expand access to simple, secure, and responsible financial services.

At Itaú, data is fundamental to ensuring operational stability and improving customer experiences. It is essential to making evidence-based decisions, understanding how systems work, and acting quickly to avoid negative impacts.

A case in point: when errors in Db2 database processes took longer than expected to resolve, Itaú applied BMC AMI Data software to accelerate fixes, and it productized the solution to minimize the impact of similar issues moving forward.

The Challenge

When downtime is unacceptable

When Itaú first encountered the database errors, its existing method for root-cause analysis was a complex manual process dependent on specific utilities and technical interpretation of results.

The process prolonged diagnosis and recovery, and Itaú was unwilling to accept the risk of downtime that could impact banking service and customer satisfaction. The bank sought a fast, automated way to diagnose the issues.

The Solution

Automated, transparent diagnoses

Itaú created a much simpler, faster, and more transparent diagnostic process by implementing BMC AMI Log Master for Db2, part of the BMC AMI Data family of solutions.

In one case, where Itaú had been analyzing an error for two days using the previous process, it applied BMC AMI Log Master for Db2 and got an accurate diagnosis in a few hours.

Using BMC AMI Log Master for Db2, the Itaú team receives diagnostic information in standardized, structured, easy-to-interpret reports. They can also interact directly with Db2 logs, which they did not do before because of the high complexity of the logs data.

The Results

Faster resolutions, productized

Based on the success of initial projects and the ease of generating diagnostic analyses, Itaú productized the analysis service, allowing users to tap into BMC AMI Log Master for Db2 when applicable, reducing technical dependencies and operational bottlenecks.

Two recent examples:

• Investigation of updates in Db2 tables: using the solution to trace the history of incorrect updates in a field of a Db2 table, Itaú identified the application creating the errors and made an adjustment to eliminate the issue.
• Support in a replication problem: during a failure in a replication tool, the team used Log Master to generate the necessary DMLs so that the application could correctly reproduce the updates in the replicated database, contributing to a faster and more precise normalization of the environment.
