dcstats {[-k statistics-type [,statistics-type]...] [-m interval] [-{a|s}]|[server-name[server-name]...]|-r}

The dcstats command outputs system statistics for specified servers, the system servers, or all servers to the system journal file at a specified interval.

Output of system statistics can be terminated with the dcstats command with the -r option specified. If the dcstats command with the -r option specified is not entered, output continues until OpenTP1 terminates.

The dcstats command does not acquire the user server-specific system statistics for a user server that is started after the dcstats command is executed.

The dcstats command cannot be used at archive-journal target nodes.

-k statistics-type

Specifies the type of system statistics output. For more than one type of statistics, a comma (,) must be placed between types.

rpc: RPC information

lck: Lock information

prc: Process information

nam: Name information

que: Message queue information

scd: Scheduling information

mcf: MCF information

dam: DAM information

tam: TAM information

trn: Transaction information

cpd: Checkpoint dump information

jnl: Journal information

osl: Shared memory management information

ist: Node-to-node shared table information

mqa: MQA service information

xat: XATMI service information

When this option is omitted, all system statistics are output.

-m interval~<unsigned integer> ((1-1440)) <<10>>

Specifies in minutes the interval at which the system statistics are to be output to the system journal file.

-a

Specifies that system statistics for the system services and all user servers are to be output.

This option cannot be specified simultaneously with the -s option.

-s

Specifies that system statistics for the entire system are to be output.

This option cannot be specified simultaneously with the -a option.

When neither the -a option nor the -s option is specified and no server name is specified, system statistics for the entire system are output.

-r

Specifies that output of system statistics is to be terminated.

If this option is specified together with any other options, the -r option is effective, and all the other specified options are ignored.

server-name~<1-8 alphanumeric characters>

Specifies the name of a user server for which system statistics are to be output.

System statistics will be output for each server whose name is specified.

If the -a option is specified, specification of a server name is ignored.

• The specification of the dcstats command is not inherited during an OpenTP1 restart. To output system statistics after an OpenTP1 restart, the dcstats command must be reentered.
• Once a user server is terminated, specification of output of its system statistics is not inherited during normal startup. To output system statistics for a user server that has been terminated, the dcstats command must be reentered after the user server's normal startup processing has been completed.
