Boost Your MySQL Debugging Skills with the General Query Log

The MySQL General Query Log provides an extensive record of all client connections and the queries they execute, making it a crucial tool for database administrators.
Enabling the MySQL General Query Log can be done through the MySQL configuration file or dynamically at runtime.
The General Query Log can be written to either a file or a table, depending on your configuration and requirements.
To enable writing to a file, add the following lines in the [mysqld] section of the MySQL configuration file: general_log = 1 and general_log_file = /var/log/mysql/mysql.log .
To enable writing to a table, run SET GLOBAL general_log = 'ON' and SET GLOBAL log_output = 'TABLE' in the MySQL command.
To check the log file, use cat, less, or tail to view the log file and use grep to search for specific queries or commands within the log.
To check the log table, log into MySQL and query the mysql.general_log table and filter the log entries using SQL commands for more specific analysis.
Understanding the specifics of the log entries is key to meaningful analysis and each log entry generally includes several important fields.
An efficient alternative to sifting through logs is Releem’s Query Analytics, feature integrated directly into Releem's dashboard, provides a comprehensive view of your MySQL database queries.
For effective MySQL debugging, monitoring, or optimizing the setup, mastering the use of the General Query Log can offer significant insights.

Creating a Global and Custom Snackbar in Vue 3 Using Vuetify and Pinia

In this post, we’ll walk through how to implement a Global and Custom Snackbar in Vue 3 with Vuetify and Pinia for state management.
To start, we’ll create our Vue 3 app using the Vuetify CLI.
Next, create a Pinia store (SnackbarStore.ts) to handle the state of the Snackbar (open/close, message, status, etc.).
We’ll create a reusable Snackbar component (GlobalSnackbar.vue) that can be used anywhere in your application.
To ensure the Snackbar is available across your entire app, import it into App.vue and pass the required props from the SnackbarStore.
Now, let’s demonstrate how to trigger the Snackbar from any component.
Once everything is in place, try clicking the button to trigger the Snackbar.
In this post, we created a global and custom Snackbar component in Vue 3 using Vuetify and Pinia.
Feel free to adjust the styling and functionality of the Snackbar to suit your needs.
Now you have a flexible, easy-to-use notification system for your Vue 3 project!

Migrating tables from IBM Db2 for z/OS to Amazon RDS for Db2

Amazon Relation Data Service (Amazon RDS) for Db2 is the latest addition to the Amazon RDS family of database engines.
AWS Mainframe Modernization is designed to modernize mainframe applications, delivering numerous benefits such as cost efficiency, scalability, flexibility, enhanced security, improved integration, support for DevOps and CI/CD, resource optimization, global reach, and continuous updates and innovation.
RDS for Db2 provides the best compatibility among other relational database management systems (RDBMSs) thereby minimizing the migration effort and timelines.
For complete list refer to RDS for Db2 features; the following features are particularly relevant for migrating data from the mainframe to RDS for Db2.
The data types, SQL queries, Java or SQL stored-procedures, user-defined functions and triggers can be migrated from Db2 for z/OS with fewer changes to run on RDS for Db2.
We outline the migration methodology for converting schema and data from Db2 on z/OS to RDS for Db2.
The IBM Db2 Administration Tool for z/OS can be used to extract DDLs for table and associated objects such as indexes, views, triggers, check constraints, nested or typed tables, identity, sequences, and more.
Python script automates the transformation of Db2 z/OS schema definitions into a format compatible with RDS for Db2, simplifying what would otherwise be a complex and error-prone task.
AWS Database Migration Service (AWS DMS) supports data migration for IBM Db2 for z/OS database version 12 as a source and RDS for Db2 as a target.
IIDR IBM Data Replication is a data synchronization tool that keeps multiple data stores in sync in near real time.

What Microsoft’s financial disclosures reveal about Azure’s market position

Microsoft has made an accounting change that removed certain mature, slower growth revenue streams from Azure, leading to an increase in growth rates for AI services contributions within Azure.
Investors are excited about the increased growth rates and AI contribution within Azure. But the accounting change reduces the size of the Azure business and its resulting revenue market share.
Leaked court documents from 2023 revealed that Microsoft’s infrastructure-as-a-service business was significantly lower than previously thought. This reduced Azure’s overall revenue, leading to an increase in AWS’ lead.
New estimates show that Azure is the fastest-growing of the big four clouds, approaching $70B in CY 2024 with 33% market share among the Big Four.
Microsoft has a commanding lead with respect to account penetration of AI, with Azure OpenAI Service, the Azure AI Studio, and the Azure ML service outpacing all others.
Microsoft is laying down the gauntlet on AI investments, in effect, forcing other vendors to disclose their AI revenue. The AI guidance is a key indicator of interest for investors and customers.
Investors will be looking at earnings season among the big three clouds (Amazon, Google, and Microsoft).
Microsoft’s reporting highlights its AI contribution to Azure and its accelerated growth rates, which experts believe will continue to be an increasingly important metric in the coming quarters.
Microsoft's CFO, Amy Hood, stated that Azure growth included eight points from AI services where demand remained higher than available capacity. How this statement maps to Azure's AI contribution is still being analyzed.

Navigating the Future of Test Automation & AI Process Automation

Test automation has become a cornerstone of modern software development, enabling teams to ensure the quality and reliability of their applications efficiently.
AI and ML is now being utilized to enhance automated testing efficiency by tools such as Testim and Mabl.
Cross-platform and mobile testing has shown static growth due to supporting frameworks such as Appium and Detox.
API testing and service virtualization is another crucial area. Tools like Postman and WireMock have simplified the creation, execution and automation of API tests.
Visual and User Interface (UI) Testing, especially for compatibility with different devices and browsers, is now more accessible through AI-powered tools such as Applitools and Percy.
Low-Code and No-Code Test Automation tools such as Katalon Studio, TestCraft, Worksoft Certify and Tosca have also shown promise for users planning to create and maintain automated tests with minimal coding background.
Selenium, on the other hand, still boasts its compatibility to support various coding languages and browser environments and provides multiple testing approaches.
Continuous Testing and DevOps Integration are also vital, with tools like TestNG that offer the capacity for parallel test execution and integration with CI/CD pipelines.
Each of these innovative tools helps to improve testing procedures for complex applications. Nevertheless, the identification of unique needs and goals remains the key to choosing the right combination of tools.
Adopting and integrating these developments can enhance testing skills and lead to software development lifecycles that are more dependable and resilient.
