Problem conclusion
HCHECKER/K Health Checker has been updated to recognize the new default for the T1BUF buffer pool. The following documentation updates are made for two Health Checker messages in SNA Messages: . . ISTH013E T1BUF/T2BUF buffer pool allocation might not be optimal for use with Enterprise Extender Explanation Check CSVTAM_T1BUF_T2BUF_EE determined that Enterprise Extender (EE) is being used (or is intended to be used) on this system and the T1BUF or T2BUF (or both) buffer pool allocation is at its default value. The default value might not be optimal for your system when using EE. Such a value assigned to this pool might cause performance degradation as a result of excessive buffer pool expansions and contractions. The default value for the T1BUF buffer pool is 18. The default value for the T2BUF buffer pool is 8. Message ISTH012I is issued prior to this message for each buffer pool (T1BUF, T2BUF, or both) that has failed this check. . . . ISTH016E T1BUF/T2BUF buffer pool allocation might not be optimal if Enterprise Extender is not being used Explanation 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 18. 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. . .
