Problem summary
**************************************************************** * USERS AFFECTED: All users of the IBM Communications Server * * for z/OS Version 1 Release(s) 12 and 13 * * IP: TCP/IP callable NMI * **************************************************************** * PROBLEM DESCRIPTION: The TCP/IP callable NMI, returns a * * non-zero value for data bytes on the * * send queue, NWMConnBuffered, and a zero * * timestamp for the age of the data, * * NWMConnOutOldestTime. * **************************************************************** * RECOMMENDATION: * **************************************************************** Module EZBNMGTC processes the TCP/IP callable Network Management Interface (NMI) request, GetConnectionDetail (NWMTcpConnType), which collects information about active TCP connections. EZBNMGTC gets control and if the connection has data on the send or the receive queues, the TCB lock is obtained to safely calculate the age (timestamp) of the data and count of the data on the receive queue. But the count of the data on the send queue was not obtained while holding the lock and the count collected was actually for data that was not in the pipe. +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.

Problem conclusion
Module EZBNMGTC has been amended to provide the correct data count and timestamp for data on the send or receive queues. * Cross Reference between External and Internal Names
