cdr start qod

The cdr start qod command starts quality of data (QOD) monitoring for replication servers.

Syntax


1  cdr start qod?  %Connect Option  (1)
Notes:

Usage

Use the cdr start qod command to start monitoring the quality of data for replications servers. If Connection Manager service-level agreements (SLAs) use a apply-failure or transaction-latency redirection policy, the Connection Manager uses quality of data information to decide where to route client connections.

Quality of data information is used for the following SLA redirection policies:
  • FAILURE: Connection requests are directed to the replication server that has the fewest apply failures.
  • LATENCY: Connection requests are directed to the replication server that has the lowest transaction latency.

You must run the cdr define qod command to define a master server before you can run the cdr start qod command. The cdr start qod command must be run on the master server.

You can run this command from within an SQL statement by using the SQL administration API.

Return codes

A return code of 0 indicates that the command was successful.

If the command is not successful, one of the following error codes is returned: 5, 217.

For information on error codes, see Return Codes for the cdr Utility.

Example

The following command starts quality of data monitoring when it is run on the master server:
cdr start qod
