Creating TRANSACTION resource definitions for CICS web support
TRANSACTION resource definitions define alias transactions for CICS® web support. An alias transaction handles the later stages of processing for an HTTP request, including receiving the request, executing the application business logic, construction of the HTTP response, and code page conversion of the HTTP response. Alias transactions can also be used for processing non-HTTP requests.
About this task
CICS supplies a resource definition for a default
alias transaction, CWBA. You might want to use alternative alias transaction
names for these purposes:
- Auditing, monitoring, or accounting
- Resource and command checking for security
- Allocating initiation priorities
- Allocating DB2® resources
- Assigning different runaway values to different CICS application programs
- Transaction class limitation
Important: Make sure that the priorities of the alias transactions
used for application-generated responses (like CWBA) are equal to,
or higher than, the priority of the transactions associated with web
attach tasks (like CWXN or CWXU). See Priorities for CICS web support transactions (CWXN, CWXU, CWBA, CW2A).
