DM_KEEPALIVE Keyword

     DM_KEEPALIVE={minutes}

This optional keyword enables keep-alive handshaking between the client and the server. The handshaking allows the server to detect a possibly hung client thread. The server terminates the thread after the specified number of minutes with no activity. If {minutes} is zero, keep-alive handshaking is disabled. This is the data manager default. Otherwise, {minutes} specifies the maximum number of minutes to wait before terminating an inactive client. The minimum value for {minutes} is three (3).

To implement the KEEPALIVE processing, the DM_KEEPALIVE keyword must be specified in the server configuration file. By default the client runtimes provide keepalive messages when the Data Manager has KEEPALIVE support enabled. However, there is a PLB_DMKEEPALIVE keyword that can be specified in the client runtime INI file to disable keepalive processing by the client runtime.

Example:

     DM_KEEPALIVE=4
