db_stop_engine function

unsigned int db_stop_engine( SQLCA * sqlca, char * parms );
  • sqlca   A pointer to a SQLCA structure. For information, see The SQL Communication Area (SQLCA).

  • parms   A null-terminated string containing a semicolon-delimited list of parameter settings, each of the form KEYWORD=value. For example,

    For a list of connection parameters, see Connection parameters.


Stops execution of the database server. The steps carried out by this function are:

  • Look for a local database server that has a name that matches the ServerName (ENG) parameter. If no ServerName is specified, look for the default local database server.
  • If no matching server is found, this function returns with success.
  • Send a request to the server to tell it to checkpoint and shut down all databases.
  • Unload the database server.

By default, this function does not stop a database server that has existing connections. If Unconditional is yes, the database server is stopped regardless of existing connections.

A C program can use this function instead of spawning dbstop. A return value of TRUE indicates that there were no errors.

The use of db_stop_engine is subject to the permissions set with the -gk server option. See -gk server option.
