RTR commands can be invoked from the RTR web browser interface or with the RTR CLI. RTR C API calls can also be invoked from these interfaces to facilitate application testing. For example, client applications can be tested before the corresponding server applications have been written by manually entering the server's C API calls, and manual tests can be done between clients and servers.
RTR commands include those used in developing applications as well as commands that let you monitor and manage the operation of a production system. See Section 1.2.1 for instructions on how to start using the RTR web browser and CLI interfaces, and see the Reliable Transaction Router Getting Started manual for an example of a manual demonstration of sending data between a client and a server.
8.1 Introduction
The commands that invoke the RTR API calls are similar to the call
names. For example, the
rtr_accept_tx()
call is invoked using CALL RTR_ACCEPT_TX at the CLI level.
Where possible, command qualifiers have been given the same names as the parameters to the API calls. See the Reliable Transaction Router C Application Programmer's Reference Manual for details about the parameters to API calls.
Most commands can be issued on remote nodes by using the /NODE=node-list or /CLUSTER qualifiers, or by preceding them with the SET ENVIRONMENT command to specify nodes where commands are to be executed. Commands such as DEFINE KEY are intended for local execution only.
Output from each command can be redirected to another device or file using the /OUTPUT qualifier.
Because the RTR command utility keeps parameter checking to a minimum, "what if" questions can be answered quickly without having to write test programs.
In a mixed RTR Version 3 and Version 4 environment, you can execute commands remotely with the /NODE qualifier. |
This section describes each command in the RTR command utility.
The command descriptions are presented in alphabetical order.
See CREATE FACILITY; ADD FACILITY is retained for compatibility reasons only.
The CALL RTR_ACCEPT_TX command causes a command server to execute the rtr_accept_tx() routine and to display the returned status.
Note
This command is not available in the RTR web browser interface.
CALL RTR_ACCEPT_TX
Command Qualifiers | Defaults |
---|---|
/CHANNEL_NAME=channel-name | /CHANNEL_NAME=RTR$DEFAULT_CHANNEL |
/CLUSTER | /NOCLUSTER |
/FORGET | /NOFORGET |
/INDEPENDENT | /NOINDEPENDENT |
/NODE[=node-list] | /NODE=default-node |
/OUTPUT[=filespec] | /OUTPUT=stdout |
/REASON[=reason] | /REASON=0 |
The CALL RTR_ACCEPT_TX command causes a command server to call the rtr_accept_tx() routine using values supplied on the command line.The numeric status returned from the call is then converted to its textual representation and displayed.
The rtr_accept_tx() routine itself is described in the C Application Programmer's Reference Manual.
The prototype of rtr_accept_tx() is:
rtr_status_t rtr_accept_tx ( rtr_channel_t channel, rtr_acc_flag_t flags, rtr_reason_t reason ) ;Table 8-1 shows the correspondence between values you supply on the command line and the C language parameter values produced and used for the call.
Table 8-1 Parameters for rtr_accept_tx C Parameter Name C Parameter Value Command Line Specification channel /CHANNEL_NAME=name flags RTR_NO_FLAGS [none] [D] RTR_F_ACC_FORGET /FORGET reason RTR_NO_REASON /NOREASON [D] reason_value /REASON=reason_value Issuing the CALL RTR_ACCEPT_TX command in preference to using the /ACCEPT qualifier with the CALL RTR_SEND_TO_SERVER or CALL RTR_REPLY_TO_CLIENT commands is only necessary when specifying an acceptance "reason" other than the default value of zero (using the /REASON qualifier).
/CHANNEL_NAME=channel_name
/CHANNEL_NAME=RTR$DEFAULT_CHANNEL
Specifies the channel for which the operation is to be performed.The command server uses a combination of the channel name and the window from which the call was issued to uniquely identify which channel to use.
channel_name is not case sensitive.
The default for channel_name is RTR$DEFAULT_CHANNEL.
/CLUSTER
/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.If neither /NODE nor /CLUSTER is specified, the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered, the command is executed only on the node where the command was issued.
Note
In environments that do not support remote command capability, the /CLUSTER qualifier causes the relevant command to be executed on the local node only. See Section 1.4 for more information./FORGET
/NOFORGET
Use /FORGET to specify the flags parameter as RTR_F_ACC_FORGET in the call rtr_accept_tx() .The default value for /FORGET is /NOFORGET, which causes the command server to use the value RTR_NO_FLAGS for the flags parameter in the call to rtr_accept_tx() .
/INDEPENDENT
/NOINDEPENDENT
Use the /INDEPENDENT qualifier to specify the flags parameter RTR_F_ACC_INDEPENDENT in the call to rtr_accept_tx() ./NODE[=node-list]
/NODE=default-node (D)
Specifies that the command is executed on all nodes specified in node-list . If node-list is omitted, the command is executed only on the node where the command was issued./OUTPUT[=filespec]
/OUTPUT=stdout (D)
Specifies that the resulting information is written to the file filespec . If /OUTPUT or filespec is omitted, the standard or default output is used./REASON[=reason]
/REASON=0
Use /REASON to supply a value for the reason parameter in the call to rtr_accept_tx() .The default value for /REASON is 0, which causes the command server to use the value RTR_NO_REASON for the reason parameter in the call to rtr_accept_tx() .
Accept the current transaction with a reason of 42.
RTR> CALL RTR_ACCEPT_TX /REASON=42 %RTR-S-OK, normal successful completion |
The CALL RTR_BROADCAST_EVENT command causes a command server to execute the rtr_broadcast_event() routine and to display the returned status.
Note
This command is not available in the RTR web browser interface.
CALL RTR_BROADCAST_EVENT [message-field1] [,message-field2,...]
[message-field1] [,message-field2...]
Specify the message to be sent (if any) as one or more comma-separated parameter values. You can use the /TYPE_OF_DATA and /LENGTH_OF_DATA positional qualifiers on each parameter value to specify the data type and length of each field.
Command Qualifiers | Defaults |
---|---|
/CHANNEL_NAME=channel-name | /CHANNEL_NAME=RTR$DEFAULT_CHANNEL |
/CLUSTER | /NOCLUSTER |
/EVENT_NUMBER=evtnum | None |
/FORMAT=fmt-string | /NOFORMAT |
/LENGTH_OF_FIELD=msg length | Depends on data type. |
/NODE[=node-list] | /NODE=default-node |
/OUTPUT[=filespec] | /OUTPUT=stdout |
/RECIPIENT_SPEC=rcpspc | /NORECIPIENT_SPEC |
/TYPE_OF_DATA=data type | /TYPE_OF_DATA=STRING |
The CALL RTR_BROADCAST_EVENT command causes a command server to call the rtr_broadcast_event() routine using values supplied on the command line.The numeric status returned from the call is then converted to its textual representation and displayed.
The rtr_broadcast_event() routine itself is described in the Reliable Transaction Router C Application Programmer's Reference Manual.
The prototype of rtr_broadcast_event() is:
rtr_status_t rtr_broadcast_event ( rtr_channel_t channel, rtr_bro_flag_t flags, rtr_msgbuf_t pmsg, rtr_msglen_t msglen, rtr_evtnum_t evtnum, rtr_rcpspc_t rcpspc, rtr_msgfmt_t msgfmt ) ;Table 8-2 shows the correspondence between values you supply on the command line and the C language parameter values produced and used for the call.
Table 8-2 Parameters for rtr_broadcast_event C Parameter Name C Parameter Value Command Line Specification channel /CHANNEL_NAME=name flags RTR_NO_FLAGS [none] [D] pmsg, msglen, msgfmt 1 [message definition parameter list with positional qualifiers ] evtnum 42 /EVENT_NUMBER=42 rcpspc "workstat*" /RECIPIENT_SPEC=
"workstat*"
The command server uses message data specified as command line parameter values to generate a record containing the message data (for the pmsg parameter), the message length (for the msglen parameter), and a record type description (for the msgfmt parameter).
/CHANNEL_NAME=channel-name
/CHANNEL_NAME=RTR$DEFAULT_CHANNEL
Specifies the channel for which the operation is to be performed.The command server uses a combination of the channel name and the window from which the call was issued to uniquely identify which channel to use.
channel_name is not case sensitive.
The default for channel-name is RTR$DEFAULT_CHANNEL.
/CLUSTER
/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.If neither /NODE nor /CLUSTER is specified, the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered, the command is executed only on the node where the command was issued.
Note
In environments that do not support remote command capability, the /CLUSTER qualifier causes the relevant command to be executed on the local node only. See Section 1.4 for more information./EVENT_NUMBER=user-event-number
The user event number associated with this broadcast, in the range of RTR_EVTNUM_USERBASE to RTR_EVTNUM_USERMAX (i.e. 0 to 250)./FORMAT[=fmt-string]
/NOFORMAT (D)
Specifies that a format string should be sent with this message.
