M204.2756 NUMBUFG reset to NLRUQG * ((NSERVS + NSUBTKS) * MAXOBUF + 15) = token * ((token2 + token3) * token4 + 15) = token5
If NUMBUFG is non-zero, its minimum valid value is the number of servers (the value of the NSERVS parameter) plus the maximum number of PST's (the value of the NSUBTKS parameter) times the value of the MAXOBUF parameter plus fifteen, all multiplied by the number of disk buffer LRU queues (the value of the NLRUQG parameter). This message is generated because a smaller value was specified for NUMBUFG.
Note: If NLRUQG is not set explicitly, it is set to the same value as NLRUQ. The value of NUMBUFG has been automatically reset to its minimum allowable value as indicated by this message.
System manager response: This is an informational message and no action is required, though it is generally a bad idea to be running with such a small number of above the bar buffers relative to the number of servers.
In fact, with so few above the bar buffers, there is probably little point in using above-the-bar buffers, at all.
Message attributes:
| RETCODEO=0 | Sets online return code |
|---|---|
| RETCODEB=0 | Sets batch (single user) return code |
| CLASS=I | Information class; the message can be suppressed with the X'02' bit setting of the MSGCTL parameter |
| AUDITMS | Writes the message with line type MS to the audit trail |
| NOCOUNT | Does not increment the error count (ERCNT) parameter |
