Overview:
Optimize 3270 data streams with CICS OTTO
IBM® CICS® Online Transmission Time Optimizer for z/OS® (CICS OTTO) improves user productivity and increases network utilization through 3270 data stream optimization. It reduces the number of characters transmitted to supported devices by making optimum use of all available orders for each device type. It keeps the screen layout of conversational terminals in memory so that only changed data is transmitted.
CICS OTTO can also reduce the contention between the devices on a communications line and between devices connected to local controllers to improve response times.
Highlights
- Examines and dynamically compresses outgoing data streams
- Eliminates repetitive characters
- Helps ensure that only changed data reaches terminals
- Increases printer speeds
- Is easy to install, customize, and use
- Operates transparently to users and applications
- Provides flexible features to control optimization
- Monitors its own operation to provide compression status
- Provides a data-stream error display for comprehensive compression-status management
Features:
Optimization techniques
IBM® CICS® OTTO provides: repetitive character elimination for 3270-type terminals and printers; transmission of only changed data for 3270-type terminals; blank elimination for 3270 SNA Character Set (SCS) printers; String Control Byte (SCB) compression for 3600/4700-type terminals.
Customized control with user exits
This feature gives you even more control over optimization functions. This user exit is called every time a message is about to be optimized and also after optimization.
Data stream error display
CICS OTTO records errors that can prevent optimization of messages, whether found in an inbound or an outbound data stream, and can display a summary of recorded errors.
Selection list for terminals and modules
The selection list allows you to select specific terminals or modules you want to include in optimization.
Exclusion list for terminals and modules
The exclusion list lets you exclude any terminal or module from optimization.
Trace data viewing
CICS OTTO can create a trace and save it in a storage area above 16 MB. Traces can be produced before and after each optimization, and can be useful for error determination.
Transaction ID option
Transaction ID can be set to yes or no. Yes means that module names in exclusion and selection lists are treated as CICS transaction IDs. No means that module names are treated as CICS program names.
HELP function
For every CICS OTTO screen, there is a HELP function that is triggered by pressing PF1. If the cursor is located in an input field, a specific HELP panel for this field is shown. Otherwise, a panel with general information on the underlying CICS OTTO screen is shown.
Benefits:
Remove repetitive data
Identify and remove repetitive data and dynamically compress 3270 data streams, and improve 3270 network resource utilization.
Monitor optimization
See how effective CICS OTTO optimization is in your environment by continually monitoring its operations and receiving progress reports on demand.
Improve transparency and visibility
Operate CICS OTTO transparently to applications and users. Operational statistics display or are written to console, and controls and settings can be entered on a temporary or permanent basis.
