Connection Options

Communications Protocol

Specifies how the CA IDMS ODBC Driver (or Type 2 JDBC Driver) communicates with CA IDMS. Options are:

• IDMS—The drivers use the CA IDMS TCP/IP feature to communicate directly with the CA IDMS system. CA IDMS r17, or later, is required.
• CCI—The drivers use the CA Common Services CCI feature to communicate with the CA IDMS system. This is the default, and is supported for all releases of CA IDMS.

SSL

Enables secure communications between the ODBC and Type 2 JDBC drivers and CA IDMS when using the IDMS communications protocol. Use the SSL tab to configure SSL options.

You can enable SSL for the Type 3 and Type 4 JDBC drivers using a special format of the URL or a IdmsDataSource object, and configure it using utilities supplied with the Java Run-time Environment.

You must use your mainframe security system to configure AT-TLS (Application Transparent Transport Level Security) to enable and configure SSL on z/OS when communicating directly with CA IDMS. SSL is not currently supported when communicating with z/VSE backend systems.

You can enable and configure SSL for the CCI communications protocol with the CAICCI Configuration application on Windows. You must also configure the CCITCP address space on z/OS to use SSL.

Host Name

Specifies the DNS name or TCP/IP address of the CCI server or the CA IDMS system. The Communication Protocol setting determines how the Host Name is used.

When used with CCI, this value overrides the default CCI server name specified using the CCI Configurator for this ODBC server only, and allows concurrent access to multiple CCI servers.

Port

Specifies the TCP/IP port of the CCI server or the CA IDMS Listener The Communication Protocol setting determines how the Host Name is used.

When used with CCI, this overrides the default CCI server port specified using the CCI Configurator for this ODBC server only. Enter 0 to use the default value set by CCI, which is normally 1202.

Wait Timeout

Specifies the number of seconds to wait for a reply from the server. This setting overrides the Reply Wait Timeout specified using the CAICCI/PC Properties dialog for this Server only. When this limit is exceeded, a communications error is returned and the connection can no longer be used. If multithreading is enabled, the application can continue processing other connections. Choose one of the following options:

• Enter 0 to use the default value set by CAICCI/PC
• Enter –1 to specify an indefinite wait (this is interpreted as the largest positive integer)
• Enter a specific time, in seconds
