Check CSVTAM_T1BUF_T2BUF_NOEE determined that Enterprise Extender (EE) might not be in use on this system and the T1BUF or T2BUF (or both) buffer pool allocation is set above its default value.
A value above the default value might not be optimal for your system when not using EE. The T1BUF and T2BUF buffer pools are designed to optimize HPR flows over Enterprise Extender connections. When EE is not being used, the buffer allocation for these pools does not need to be set above the default values. The default value for the T1BUF buffer pool is 16. The default value for the T2BUF buffer pool is 8.
Message ISTH015I is issued prior to this message for each buffer pool (T1BUF, T2BUF, or both) that failed this check.
The system continues processing.
Contact the system programmer.
If you intend to use EE on this system, IBM® suggests that the T1BUF and T2BUF buffer pools be monitored and tuned to minimize the number of expansions. Minimizing buffer pool expansions will decrease internal buffer overhead processing which should increase throughput while reducing CPU consumption. These buffer pools can be monitored using the D NET,BFRUSE,BUF=(T1,T2) command. Once the appropriate allocation values for the T1BUF and T2BUF buffer pools have been determined, you can change the T1BUF and T2BUF Start option allocation values before next starting VTAM®. If you do not intend to use EE on this system, you can change the T1BUF and T2BUF Start option allocation values to the default values before next starting VTAM.
See the buffer pool information in z/OS Communications Server: SNA Resource Definition Reference for more information about the T1BUF and T2BUF Start Options. See the Display BFRUSE command information in z/OS Communications Server: SNA Operation for more information on the D NET,BFRUSE command.
