As operating systems have matured many platform specific
techniques for managing processing have been conceived. Connect CDC (SQData) can be configured on each supported platform to take
advantage of those techniques and facilitates operation in
heterogeneous environments using its own TCP/IP based communication
capabilities.
In addition to the traditional methods of platform specific
application installation, configuration and operating methods,
interest in container technology has grown in recent years. While
Connect CDC (SQData) is not provided as a containerized product,
customers may create custom containers for various components.
Precisely is container tool-chain agnostic, we can assist you as
you explore integrating containers into your infrastructure.
z/OS
|
IBM's mainframe operating system provides many unique facilities that Connect CDC (SQData) exploits for performance, reliability and cost effectiveness:
- Operate as standard zOS JOBS or Started Tasks
- Console command interface for both JOBS and Started Tasks
- ISPF panel Interface for Configuration and Operation
- System LogStreams used when possible for performance and reliability
- zIIP Engine support for enhanced CPU cycle efficiency.
- IMS Log Capture LogStream I/O Operations
- zLogc Publisher LogStream I/O Operations for both captured IMS and VSAM change data capture
- NaCL based Publisher encryption of CDC payload from zOS to other platforms

Linux/AIX/UNIX
|
Increasingly Linux open systems based on UNIX are the platform
of choice for distributed and cluster based operations:
- Change Data Capture components may run on small commodity based
systems and VM's remotely capturing Db2/LUW and Oracle.
- Apply and Replicator Engines may run on small commodity based
systems and VM's remotely writing to all Targets.
- Apply and Replicator Engines running on Linux can utilize
secure TLS connections to Capture components running on z/OS under
IBM's Application
Transparent Transport Layer Security (AT-TLS).
- Apply and Replicator Engines operate as Kafka Producers when
running on Linux, the only platform with an officially supported
Kafka C language API.
- Apply and Replicator Engines may write directly to HDFS/ Hadoop
when running on Linux, the only platform with an officially
supported HDFS C language API.

Windows
| Apply Engines may run on Windows and can run under a daemon
configured as a Windows Service. |
Cross Platform
|
Features that facilitate management, control and security:
- TCP/IP is used exclusively for cross platform
communication
- SQDaemon provides cross platform authentication of
communication and control between components
- Captured data transported between platforms may be secured by
VPN or NaCL based encryption or using TLS encryption between zOS
and Linux
