Inter Data Communications

Inter Data Communications (IDC) is a TCP/IP-based protocol that allows one Accelerator Loader server to communicate with another Accelerator Loader server. You can set up multiple Accelerator Loader servers on multiple LPARs in your z System infrastructure. Once IDC is configured, an LPAR can access data and other resources on one or more LPARs.

For example, consider a z System infrastructure that has multiple LPARs configured. If Adabas is running on one of the LPARs and you need to access Adabas from another LPAR, then you can use IDC to enable communication between the two LPARs. To use IDC, you need to install Accelerator Loader server on both the LPAR running Adabas (the target LPAR) the LPAR needing access (the source LPAR). To enable Inter Data Communications, you need to configure server parameters on both the source and the target LPARs so that communication is established between the two LPARs.

After IDC is enabled on an LPAR, the Accelerator Loader server on the LPAR can also communicate with other LPARs where Accelerator Loader server is installed.

Accelerator Loader server allows some data transformations to run on a z System Integrated Information Processor (zIIP) specialty engine for significantly reduced MIPS capacity usage. In this example, the source LPAR can access the Adabas data on the target LPAR and use the zIIP processor to perform data transformations. To view which Accelerator Loader components support zIIP, see zIIP support.
