VTAM® issues this message in response to a VARY ACT command when the buffers are too small. The buffer size of buffer pool poolname must be at least minsize for VTAM to activate a line.
poolname is the name of the buffer pool. See the z/OS Communications Server: SNA Network Implementation Guide for an explanation and description of buffer pools and for general information on buffer pool specification and allocation.
minsize is the minimum buffer size for the type of line you tried to activate.
Line activation fails. Processing continues.
Save the system log for problem determination.
Change the buffer size for poolname in the VTAM start list ATCSTRxx. After the VTAM start list is corrected, restart VTAM and enter a VARY ACT command for the line.
