NLXB= parameter for procedures

Use the NLXB= parameter in procedures to specify the number of parallel sessions to be added during the startup of an IMS system. The default is 0.

The NLXB value is added to the value specified in the SESSION parameter during system definition to increase the number of link extension blocks (LXB) generated for each link control block (LCB).

If NLXB is specified when the maximum value is already specified on the SESSION parameter in the definition of the MSC physical link (MSPLINK), the NLXB value is ignored. This parameter is valid for MSC with VTAM® and TCP/IP only and does not apply to Intersystem Communication (ISC).
