Communications/Transactions Guide and Reference

APPC Connection Spec - Settings

Use the APPC Connection Spec - Settings window to change the attributes of an APPC Connection Spec. These attributes represent a set of protocol-specific communication parameters for an APPC conversation.

Destination tab for APPC Connection Spec

Use the Destination tab to specify the transaction program (TP) and logical unit (LU) you want to connect to:

Partner TP name
In the Partner TP name field, type the name of the transaction program (TP) you want to access on the remote host
Partner LU alias
From the Partner LU alias field, type the alias of the logical unit (LU) you want to connect to on the remote host. This is the LU through which the partner TP accesses the network.
Fully qualified partner LU name
In the Fully qualified partner LU name field, type the fully qualified network name of the remote LU you want to connect to. You do not need to specify a value in this field, if you provide a value in the Partner LU Alias field.
Userid
In the Userid field, type the user ID you want to use to access the remote system.
Password
In the Password field, type the password you want to use to access the remote system.
Security
From the Security combo box, specify the level of APPC conversation security to use (Same, Pgm, or None).

Conversation tab for APPC Connection Spec

Use the Conversation tab to specify parameters that apply to the conversation:

Local TP name
In the Local TP name field, type the name you want to use to identify the local program to the network. If you do not provide a value in this field, VisualAge automatically generates a unique name at run time.
Local LU alias
Use the Local LU alias combo box to specify the local logical unit you want to connect to on the network. The LU aliases are defined in your communication software configuration.
Mode
From the Mode combo box, specify the transmission mode to use for the session. This mode can be any mode defined in the local Communications Manager configuration. The default value is #INTER.
Sync level
From the Sync level combo box, specify the level of APPC synchronization to use for the conversation.
Return control
From the Return control combo box, specify when the local LU should return control to the VisualAge application following an attempt to open a connection.

Data Attributes tab for APPC Connection Spec

Use the Data Attributes tab to specify program initialization parameters and data handling options for a conversation:

Code page
In the Code page field, type the character code page used by the remote system. The default code page is whatever the current code page is for the system you are developing your application on.
Buffer length
In the Buffer length field, type the size of the memory buffer VisualAge should allocate for the data sent to and received from the server. For a remote external function call, the buffer size must be at least as large as the total size of the record used by the function. The default value for this field is 1024.
Big endian
Select Big endian to specify you want the partner to use the bigEndian format. If you do not select Big endian, the partner uses littleEndian format.
