What does Attach Facility do?
Attach Facility enables batch applications to access DB2 data directly, without requiring execution within the TSO environment. It streamlines the interaction between batch processes and DB2 databases, potentially improving performance. This is achieved through the DB2 Call-Attach Facility (CAF).
Is this a system, application, or tool?
Attach Facility is a middleware solution. It provides a bridge between batch applications and DB2 databases, facilitating data access and manipulation. It is not a standalone application but rather a system enhancement.
What types of organizations use this?
Organizations that rely heavily on batch processing for data warehousing, reporting, or ETL (Extract, Transform, Load) operations are prime candidates. These are often large enterprises in industries like banking, insurance, and retail that require efficient DB2 access from batch jobs.
When should we consider Attach Facility?
Consider Attach Facility when batch jobs accessing DB2 are experiencing performance bottlenecks or when there is a need to reduce TSO overhead. It is also beneficial when aiming to simplify the architecture for batch/DB2 interactions.
What are the alternatives to Attach Facility?
Alternatives include other DB2 connectivity solutions and methods for optimizing batch job performance, such as tuning SQL queries, improving data access patterns, or using alternative data access methods. However, Attach Facility provides a direct connection without TSO.
