There are a number of ways in which terminal statistics are important for performance analysis. From them, you can get the number of inputs and outputs, that is, the loading of the system by end users. Line-transmission faults and transaction faults are shown (these both have a negative influence on performance behavior).
This section contains the following statistics:
These statistics are gathered for each terminal, including ISC and IRC (MRO) sessions.
These statistics can be accessed online using the EXEC CICS® COLLECT STATISTICS TERMINAL command, and are mapped by the DFHA06DS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.
In addition to this, this DSECT should be used to map the terminal totals record.

Conn ID | A06SYSID | is the owning connection name of this terminal/session.
Reset characteristic: not reset
|
No. of Xactions | A06TEOT | is the number of transactions, both conversational and
pseudoconversational, that were started at this terminal. The transaction
count is less than input messages if conversational transactions are being
used.
Reset characteristic: reset to zero When the operator signs off, the transaction count is not reset. At this time, message DFHSN1200 is issued containing the transaction count for that operator.
|
Xaction Errors | A06TEOE | is the number of transactions associated with this particular
terminal that could not be started. This could mean that a transaction identifier
has not been defined in the CSD data set, or that the operator does not have
the proper security to enter the transaction, or that the transaction has
been disabled.
Reset characteristic: reset to zero When the operator signs off, the transaction error count is not reset. At this time, message DFHSN1200 is issued containing the transaction error count for that operator.
|
Storage Viols | A06CSVC | is the number of storage violations that have occurred
on this terminal.
Reset characteristic: reset to zero

A06TENO | See note.
Reset characteristic: reset to zero
|
Xmission Errors | A06TETE | is the number of errors for this terminal, or the number
of disconnects for this session.
Reset characteristic: reset to zero
|
Pipeline Message: NOT IN THE DFHSTUP REPORT | A06TCNT | is the total throwaway count.
Reset characteristic: reset to zero
|
Pipeline Message: NOT IN THE DFHSTUP REPORT | A06SCNT | is the number of consecutive throwaways.
Reset characteristic: reset to zero
|
Pipeline Message: NOT IN THE DFHSTUP REPORT | A06MCNT | is the maximum throwaway count.
Reset characteristic: reset to zero
|
Pipeline Message: NOT IN THE DFHSTUP REPORT | A06PRTY | is the terminal priority
Reset characteristic: not reset
|
Pipeline Message: TIOA Storage | A06STG | is the TIOA storage allowed at this terminal.
Reset characteristic: reset to zero
|
Autoinstall Time: Logon | A06ONTM | is time at which this terminal/session was autoinstalled.
This time is expressed as hours:minutes:seconds.decimals. The DSECT field contains the value as a store clock (STCK) value in
local time.
Reset characteristic: not reset
|
Autoinstall Time: Logoff | A06OFFTM | is the time at which this terminal/session was logged
off. This time is expressed as hours:minutes:seconds.decimals. The DSECT field contains the value as a store clock (STCK) value in
local time.
Note that this field is only set on an Unsolicited Statistics (USS) record. Reset characteristic: not reset
|
Autoinstall Time: NOT IN THE DFHSTUP REPORT | A06GONTM | is the time at which this terminal/session was autoinstalled.
The DSECT field contains the value as a store clock (STCK) value in GMT.
Reset characteristic: not reset
|
Autoinstall Time: NOT IN THE DFHSTUP REPORT | A06GOFTM | is the time at which this terminal/session was logged
off. The DSECT field contains the value as a store clock (STCK) value in GMT.

Note:
Input messages and output
messages are the amount of message activity per terminal. Input and output
messages should represent the message traffic between CICS and the terminal.
Input traffic should be the result of operator initiated input: that
is, initial transaction input or input as a result of a conversational read
to the terminal. Output messages should be output written by the application
program or messages sent by CICS. Input and output messages can vary because of differences in the application program being used on different terminals. ATI-initiated transactions would typically not have terminal input but could result in one or many output messages. A batch oriented terminal could initiate a single transaction that did multiple reads to the terminal resulting in multiple input messages. The differences between the remote and local terminal counts may be a result of different applications that run on them. Otherwise, they should be similar. |
