Java Application Monitoring Quiz

Study Notes

Java-based Application Monitoring in 24/7 Environment with Linux

Utilize the tail command for real-time monitoring of system logs related to Java applications.
Analyze log files in /var/log to identify common errors such as NullPointerException or OutOfMemoryError.
Implement alert systems to notify staff of critical issues in real-time, ensuring constant observation.

Core Banking Applications and Finacle Customization

Monitor batch jobs using job scheduling tools, ensuring timely checks and balances in core banking processes.
PL/SQL scripting automates data verification and error resolution, enhancing the efficiency of ticket management.
Customizing Finacle can involve optimizing database queries, significantly enhancing transaction processing speeds.

Enterprise Network Devices Management

Key management steps include device configuration, monitoring network performance, and compliance checks.
Conduct regular failover tests to ensure network redundancy and utilize monitoring tools for real-time performance tracking.
Establish a governance process for managing network device policies, ensuring user access reviews are periodically conducted.

Deployment and Management of AIX/Redhat/Solaris Servers

Deploy Redhat servers by creating bootable media, configuring partitions, and installing necessary packages in a production setup.
Monitor CPU and memory performance metrics such as load averages, memory usage percentage, and CPU idle time for AIX/Solaris.
Ensure seamless backup restoration by documenting procedures and validating failover test scenarios regularly.

Oracle DB Deployment and Monitoring

RMAN (Recovery Manager) is used for efficient backup and restoration processes, offering incremental backups and full recovery options.
Employ execution plans and indexing strategies for query tuning, alongside tools like AWR for performance monitoring in Oracle DB.
Manage user roles and permissions diligently to ensure data integrity during disaster recovery drills.

MySQL, Postgres, MS SQL Server Deployment and Monitoring
