Approach

Understand the Architecture

• Operating System

• Database

• Middleware

• Virtualization

• Cloud or on-Prem

Scalability Potential

• Hardware/Virtualization

  • Capacity Available

    • CPU / Memory /Disk allocation

  • Storage Performance

    • ISCSI / vSAN / Encrypted?

• Software

  • Non Performant code?

    • Parallelism/Threading

    • Bulk/Non Bulk approaches

  • Database tuning

    • Indexing

    • Cost based Optimizer requirements

      • Schema statistics

    • Purge ability

      • Partitioning

  • Java Tuning Parameters(JVM)

Identify Improvement Candidates

• Bottlenecks

• Analyze execution over time / Execution plans / Resource usage

• identify potential candidates for improvement

Code RACI

• Product Code

  • Who fixes? When can fix be incorporated into base product?

• Custom Code
