VTAM® cannot execute a DISPLAY APING command because a prior DISPLAY APING request is still executing. VTAM only allows one DISPLAY APING command to execute at a time.
VTAM rejects the command.
Reenter the command once the prior APING completes execution. See the z/OS Communications Server: SNA Network Implementation Guide for instructions on terminating the currently executing APING, should that become necessary.
None.
