Personal Communications 6.0.18
IBM Personal Communications 12.0.1
APAR status
Closed as program error.
Error description
Replaced PCOMM v6.0.11 with v12 and any screen size larger than 27X150 gets responses measured in minutes. Smaller screen sizes are fine. PCOM V6.0.12 had the same problem.
Local fix
Add keyword - ReceiveBufferSize=32768 to Telnet3270 section of WS profile
Problem summary
**************************************************************** * USERS AFFECTED: * * IBM Personal Communications secure sessions with screen * * sizes 27x132 and larger. * **************************************************************** * PROBLEM DESCRIPTION: * * Slow secure emulator session response to host updates when * * using screen size of 27x132 and larger. * **************************************************************** * RECOMMENDATION: * **************************************************************** IBM Personal Communications secure emulator sessions created with larger screen sizes (27x132 and beyond) may slow down when the emulator communicates with the host. For example, while using 62x160 screen size, page up and page down operations may show X-CLOCK for several minutes, and keyboard is inhibited during this period.
Problem conclusion
In a secure session, default buffer size of the receiving data buffer is set to 16K. This was found to cause issues when encrypted data was larger than the buffer size. PCSTLNET.DLL has been changed to set the default receive buffer size for a secure session to 32K. We recommend our users not to customize the receive buffer size while configuring the emulator sessions. Fix scheduled for IBM Personal Communications 6.0.18 Refresh Pack and 12.0.1.0 Refresh Pack
