TCP/IP report
The TCP/IP report is produced using a combination of EXEC CICS INQUIRE TCPIP and EXEC CICS EXTRACT STATISTICS TCPIP commands. The statistics data is mapped by the DFHSOGDS DSECT.

| Performance tuning for HTTP connections | Indicates whether performance tuning for HTTP connections is
enabled. Source field: SOG-SOTUNING |
| Listener pausing listening for HTTP connections | Indicates whether the listener has paused listening for HTTP
connection requests because the number of tasks in the region has reached the limit for accepting
new HTTP connection requests. Source field: SOG-PAUSING-HTTP-LISTENING |

has been notified that the number of tasks in the region has reached
the limit for accepting new HTTP connection requests. Source field: SOG-TIMES-AT-ACCEPT-LIMIT |
| Last time paused listening | The last time the socket listener paused listening for HTTP
connection requests because the number of tasks in the region had reached the limit for accepting
new HTTP connection requests. The DFHSTUP report expresses this time as day/month/year
hours:minutes:seconds:decimals; however, the DSECT field contains the time as a store clock
(STCK) value in local time. If the DFHSTUP report shows the date and time as --/--/----
--:--:--:----, that indicates that the listener has never paused listening for HTTP
connection requests since the statistics were last resetSource field: SOG-TIME-LAST-PAUSED-LISTENING |
| Region stopping HTTP connection persistence | Indicates whether the
region is closing existing persistent connections when their next request completes and is making
new connections non-persistent, because the number of tasks in the region has exceeded the
limit. Source field: SOG-STOPPING-PERSISTENCE |
| Times region stopped HTTP connection persistence | The number of times the region took action to close existing
persistent connections when their next request completes and make new connections non-persistent,
because the number of tasks in the region had exceeded the limit. Source field: SOG-TIMES-STOPPED-PERSISTENT |
| Region last stopped persistence | The last time the region took action to close existing persistent
connections when their next request completes and make new connections non-persistent, because the
number of tasks in the region had exceeded the limit. If the DFH0STAT report shows the date and time
as --/--/---- --:--:--:----, that indicates that this situation has not occurred
since the statistics were last reset. Source field: SOG-TIME-LAST-STOPPED-PERSIST |
| Persistent connections made non-persistent | The number of times a persistent HTTP connection was made
non-persistent because the number of tasks in the region had exceeded the limit. Source field: SOG-TIMES-MADE-NON-PERSISTENT |
| Times disconnected a connection at max uses | The number of times a persistent HTTP connection was disconnected
because the number of uses had exceeded the limit. Source field: SOG-TIMES-CONN-DISC-AT-MAX |
