Description
CBLDCMCF('TACTCN ') establishes connection.
Normal termination of CBLDCMCF('TACTCN ') indicates that the connection establishment request was accepted successfully by the protocol product. However, this does not necessarily mean that connection with the remote system has been established.
If you intend to perform any connection-related operation after calling CBLDCMCF('TACTCN '), first use CBLDCMCF('TLSCN ') to check the connection status.
Data areas whose values are set in the UAP
data-name-A
Specify VALUE 'TACTCN' for the request code indicating connection establishment.
data-name-C
Specify how to specify the connection that is to be established.
data-name-D1
Specify a space.
data-name-D2
Specifies whether functionality that depends on the communication protocol is being used.
data-name-D3
Specify a space.
data-name-E
Specify the MCF communication process identifier of the MCF communication service for the connection that is to be processed. The permitted value range is from 0 to 239.
This argument is ignored when a logical terminal name is used to request connection establishment.
If you specify 0, the system searches for the MCF communication service to which the specified connection ID belongs. In a configuration where many MCF communication services are running or when you issue this function many times from a UAP, we recommend that you specify the MCF communication process identifier.
data-name-F1
Specify the logical terminal name or connection ID of the connection that is to be established. Express the logical terminal name or connection ID as a maximum of 8 bytes. If the specified name is shorter than 8 bytes, pad the name with trailing spaces.
data-name-F2, data-name-G, data-name-H, data-name-I, data-name-J
Specify a space.
data-name-K1
Specify the length of a protocol-specific area. You can specify a maximum of 1024 bytes.
If you do not use functionality that depends on the communication protocol, specify 0.
data-name-K2
Specify contents for the protocol-specific area.
The permitted value depends on the communication protocol being used. For details, see the applicable OpenTP1 Protocol manual.
data-name-L
Specify 0.
Data area to which a value is returned from OpenTP1
data-name-B
A status code of 5 digits is returned.
Status codes
Status code | Explanation |
---|---|
00000 | Normal termination. |
71001 | CBLDCMCF('TACTCN ') cannot be accepted because MCF is under start processing. |
71002 | CBLDCMCF('TACTCN ') cannot be accepted because MCF is under termination processing. |
71004 | A memory shortage occurred during CBLDCMCF('TACTCN ') processing. |
71005 | A communication error occurred. For the cause, see the message log file. |
71006 | An internal error occurred. For the cause, see the message log file. |
71007 | The specified connection name has not been registered. |
71008 | The specified logical terminal name has not been registered. |
71009 | CBLDCMCF('TACTCN ') is not supported by the applicable communication process. |
71010 | Although the request to establish connection was issued to the MCF communication process, the request was not accepted. For the cause, see the message log file. |
71011 | CBLDCMCF('TACTCN ') cannot be accepted because the connection has been deleted. |
71014 | The specified logical terminal name belongs to TP1/NET/NCSB or TP1/NET/X25-Extended; or, the specified connection group name belongs to TP1/NET/OSI-TP or TP1/NET/TCP/IP. |
72028 | The value specified for data-name-A is invalid. |
72052 | <If '0' or a space is specified for data-name-D2> A nonzero value is specified for data-name-K1. |
<If '1' is specified for data-name-D2> A value smaller than 0 or greater than 1024 is specified for data-name-K1. |
|
72053 | A nonzero value is specified for data-name-L. |
72058 | The value specified for data-name-C is not 'LE', CN', or a space. |
72059 | The value specified for data-name-D1 or data-name-D3 is not a space. |
The value specified for data-name-D2 is not 1, 0, or a space. | |
72061 | A value smaller than 0 or greater than 239 is specified for data-name-E. |
72063 | A space is specified for data-name-F1. |
72065 | The value specified for data-name-F2 is not a space. |
72066 | The value specified for data-name-G is not a space. |
72068 | The value specified for data-name-H is not a space. |
72070 | The value specified for data-name-I is not a space. |
72072 | The value specified for data-name-J is not a space. |
72074 | The character string specified for data-name-F1 contains an invalid character. |
