Establishing communication stream with database control agent over which database commands are dispatched for execution against database

A management server on a management network, comprising:

• a processor;
• and
• a memory storing management program code executable by the processor to perform processing comprising:
• establishing a first communication stream with a first database control agent for a first database on a first database network separate from the management network, without opening any ports on the first database network for access by the management program code;
• instantiating a first publication/subscription channel associated with the first database and subscribing the first database control agent to the first publication/subscription channel;
• receiving a first database command for the first database from first client program code;
• publishing the first database command to the first publication/subscription channel, wherein publication causes dispatch of the first database command to the first database control agent over the first communication stream, for execution against the first database;
• receiving execution results of the first database command from the first database control agent over the first communication stream;
• returning the execution results to the first client program code in satisfaction of the first database command;
• establishing a second communication stream with a second database control agent for a second database on a second database network separate from the management network, without opening any ports on the second database network for access by the management program code;
• instantiating a second publication/subscription channel associated with the second database and subscribing the second database control agent to the second publication/subscription channel;
• receiving a second database command for the second database from second client program code;
• and
• publishing the second database command to the second publication/subscription channel, wherein publication causes dispatch of the second database command to the second database control agent over the second communication stream, for execution against the second database.

A method performed by a management server and comprising:

• establishing a first communication stream with a first database control agent for a first database on a first database network separate from a management network without opening any ports on the first database network for access by the management server;
• instantiating a first publication/subscription channel associated with the first database and subscribing the first database control agent to the first publication/subscription channel;
• receiving a first database command for the first database from first client program code;
• publishing the first database command to the first publication/subscription channel, wherein publication causes dispatch of the first database command to the first database control agent over the first communication stream, for execution against the first database;
• receiving execution results of the first database command from the first database control agent over the first communication stream;
• returning the execution results to the first client program code in satisfaction of the first database command;
• establishing a second communication stream with a second database control agent for a second database on a second database network separate from the management network, without opening any ports on the second database network for access by the management program code;
• instantiating a second publication/subscription channel associated with the second database and subscribing the second database control agent to the second publication/subscription channel;
• receiving a second database command for the second database from second client program code;
• and
• publishing the second database command to the second publication/subscriptio channel, wherein publication causes dispatch of the second database command to the second database control agent over the second communication stream, for execution against the second database.
