POOL INFO
POOL INFO
The POOL INFO section in the statistics display provides information about the two
storage pools in memory: TERMPOOL and SERVERPOOL.
Example 5-2 shows only the POOL INFO section of the sample TCP statistics.
The Table 5-1 lists the statistics for the storage pools and what they indicate.

Table 5-1. TCP Statistics for POOL INFO
Statistic For TERMPOOL and SERVERPOOL, Indicates:
SIZE Maximum number of bytes available in the pool, as defined by the SET
TCP TERMPOOL and SET TCP SERVERPOOL commands.
(The current number of free bytes available in each pool area changes as
the TCP allocates and reclaims I/O buffers for terminal and server
operations.)
REQ CNT Number of requests the TCP receives for buffer allocation.
MAX ALLOC Greatest number of bytes allocated from the pool area at one time for all
I/O buffers. (Because the TCP requires buffer space for its own operations,
the buffer allocations under TERMPOOL may be larger than the size of I/O
buffers alone. The size used for internal operations may vary by terminal
type.)
AVG ALLOC Average number of bytes allocated from the pool area for all I/O buffers.
CUR ALLOC Current number of bytes allocated from the pool area for all I/O buffers.
MAX REQ Size of the largest request for buffer allocation. (The number actually
displayed is four bytes larger than the maximum buffer requested because
the system adds four bytes to be used as boundary tags.)
AVG REQ Size of the average request for buffer allocation.
