Available CCI.INI Options for CCINETB

The CCINETB parameters which are listed below must be specified in the [ccinetb-base] section of the CCI.INI file:

• AdapterLoc, default setting "0"

  This parameter specifies the adapter and protocol binding over which CCINETB should be used.

• DefaultBuffLen, default setting "4096"

  This parameter specifies, in bytes, the default size of the receive buffer used internally by CCI. The default value for this parameter on Windows NT and Windows 95 is 4096 bytes.

  If the data to be received is larger than the buffer, CCINETB performs multiple receive operations automatically until all the data has been received. Hence this parameter can be used to tune CCINETB to perform the minimum number of network receives whilst optimizing memory usage. For example, if you know that your CCI application will transmit data in buffers larger than 4096 bytes then increase this parameter. The maximum buffer size allowable is 65535 bytes.

• Commands, default setting "20"

  This parameter specifies the maximum number of NetBIOS commands which can be outstanding at any one time. This parameter is used by CCINETB to allow it to communicate using NetBEUI. By default, CCINETB sets this parameter to 20 on Windows NT and Windows 95.

  On Windows 95 the default system value for the number of commands available is actually 12 . This means that the default for the maximum number of NetBIOS commands is overridden by Windows 95.

  If you are running client applications under Windows 95 this value may be sufficient. However, if you are running a server application or testing between Windows 95 sessions you may want to increase this value.

  CCINETB leaves one command outstanding for each end of a CCI session between a client and a server. It also uses two additional commands for listening for incoming connections and additional commands for canceling sessions. So, a CCI installation running a CCI server which services up to 10 connections needs to increase this parameter by at least 15 (i.e. to 27), ensuring that enough commands remain for other NetBIOS applications.

  To increase this system defined maximum:

  1. Select the Network option in Control Panel and click the Configuration tab.
  2. Double click on the NetBEUI network adapter protocol binding that you want CCINETB to use.
  3. Click on the Advanced tab, select NCBS and alter the value.
  4. Click on OK.
  5. Shutdown and restart Windows 95 so that the changes take effect.
• Sessions, default setting "10"

  This parameter specifies the maximum number of NetBIOS sessions which can be active at any one time. By default, CCINETB sets this parameter to 10 on Windows NT and Windows 95.

  On Windows 95 the default system value for the number of sessions available is also 10. To increase the number of sessions available you must modify the system value for Windows 95. You may want to increase this value depending on how many other applications on your system require NetBIOS.

  CCINETB uses a NetBIOS session for each CCI session between a client and a server. So, a CCI installation running a CCI server which services up to 10 connections needs to increase this parameter by at least 10 (i.e. to 20), ensuring that enough sessions remain for other NetBIOS applications.

  To increase the system defined maximum:

  1. Select the Network option from the Control Panel and click on the Configuration tab.
  2. Double click on the NetBEUI network adapter protocol binding that you want CCINETB to use.
  3. Click on the Advanced tab, select Maximum Sessions and alter the setting of Value.
  4. Click on OK.
  5. Shutdown and restart Windows 95 so that the changes take effect.
• Names, default setting "4096"

  This parameter is used to specify the maximum number of NetBIOS names which can exist in the NetBIOS name table at any one time. For Token Ring this includes the universally administered address.

  The default value for this parameter on Windows NT and Windows 95 is 2.

  The value of this parameter determines the maximum number of CCI servers which can exist at any one time.
