When trying to obtain Db2 metrics using CE-APM or native Sysview Db2 option receiving access denied error

Products

• SYSVIEW Performance Management Option for DB2 for z/OS
• Database Management for DB2 for z/OS - Performance Suite

Issue/Introduction

Unable to display Db2 metrics using the CE-APM or Sysview for DB2 interface.

The XNET logfile states:
Listener error: PXNWTSS function BIND - 13: Access denied 

Environment

CE-APM, Sysview (DB2 option), Sysview Performance Management Option for Db2 for z/OS (IDB@),  PTXNET (commonly known as XNET)

Cause

For some reason TCPIP would not allow the CE-APM or Sysview users the ability to bind to the port that was established for XNET. 

Resolution

The error: Listener error: PXNWTSS function BIND - 13: Access denied as seen in the XNET logfile is stating that TCPIP (for some undetermined reason)
will not allow a socket bind to XNET's port.  Specifying a different port number in the XNET started task, Sysview's Db2 parmlib
member, and the Wily-Introscope's properties file, and then cycling the XNET and CE-APM started tasks corrected the access denied condition,
allowing the successful display of Db2 metrics.
