Disable the c-treeACE Communication SubSystem

c-treeACE can now be configured to disable its communication subsystem, such that only bound clients can use the server.

  • COMM_PROTOCOL DISABLE

When this option is specified the communication subsystem is disabled at startup, and remains disabled during the entire lifetime of the server process. This feature is useful when c-treeACE is loaded as a .dll or shared library into an application server process. Although external clients are prevented from using c-treeACE, threads in the application server process can use the c-treeACE subsystem. This option can also be used to prevent ISAM-level access to c-treeACE SQL.

When this option is in effect, the server logs the following message to CTSTATUS.FCS:

c-tree Server communication subsystem is disabled.
