Central Client Control Overview

The Conductor4SQL Central Client Control button on the Central ribbon provides you with a number of options to manage and control any of your installed Client Servers.

Here are some examples of what you might want to do here:

• You want to run a query to check the status of all your client side databases. - See Send User Query section
• You want to alter a table at all your in-country stores. - See Send User Command section
• You want to ensure that all your table meta-data and stored procedures are identical across your entire environment. - See Send System Query section
• You want to enable DDL Event Auditing at all your in-country stores as a core stored procedure keeps changing and you want to find the culprit. - See Send System Command section
• You have Word document you want to send to all your clients stores updating all the store operators on the latest corporate policy. - See Send File section.
• You have a day end Excel extract at 1000+ stores that you would like to pull to the Central server rather connecting to each server individually. - See File Pull section
• You sent out a User Query to all of in country stores and you want to see everywhere where that query failed. - See Central Client Control History

Send system Commands and Queries

• System Commands - are pre-configured commands for controlling and checking Conductor4SQL clients. E.g. Client Pulse Check and Remove top (N) messages from Client Queue
• System Queries - pre-defined queries mostly used for metadata compare. E.g. Client Differences - Procedures

Send System Command

To send a System Command select the command from the System Commands drop down list,

Click on the Execute Command button and choose which clients you would like to send the command to from the context menu (All, Group or Some).

The available system commands are:

• Remove Top (N) Messages From Client Queue - Remove error messages from the queue
• Enable Client Queue - Enable the selected queue at the client
• Disable Client Queue - Disable the selected queue at the client
• Get Client Report Data - Get report data for all of the activated reports

• Enable Client Event Notifications - Enable client event auditing for the selected clients
• Disable Client Event Notifications - Disable client event auditing for the selected clients

Client Pulse Check

This command's prime objective is to check if a client is active and return a status condition. This condition will display the operational status of the Client on the Dashboard.

Remove Top (n) messages from Client Queue

This command is used to clean up a Client Queue if there are problematic messages that still exist. You may choose the number of messages you want to remove from the top end of the list.

• Number of message to remove - Number of messages to remove from the queue
• Re-enable the client queue - Toggle to enable or disable re-enabling the queue after removing the messages
• Reason - The reason for removing the messages

• Queue Name - the queue to remove the messages from

Enable Client Queue

This command enables any Client which may be in a disabled condition. Clients are normally disabled when a bad SQL command is submitted.

Disable Client Queue

This command disables the Client queue which is useful if you want to send messages to a client but you do not want the client to process the messages at this point in time.

Send System Query

To send a System Query select the query from the System Queries drop down list,

Click on the Execute Command button and choose which clients you would like to send the command to from the context menu (All, Group or Some).
