Use the purge config command to remove the data from all queues associated with a configuration without removing the queues themselves or deactivating the configuration. Avoiding a deactivation avoids the need for SharePlex to recalculate the configuration data. This saves time when the tables are large and numerous, enabling replication can start sooner.
Issue the purge config command on the source system to affect the source system and all target systems in the configured routes. Should any SharePlex process stop prior to or during the purge config activity, the command also stops working. When the process starts again, the command resumes working. Thus, purge config works even when the network is temporarily unavailable — the command remains in the queues until the connection is restored.
Cautions for using the purge config command
- Do not activate a configuration and then follow the activate config command with a purge config command. You might be purging more than just queued data, including the configuration information that controls replication, thus rendering the activation invalid.
- When there are multiple active configurations on the same source system, use the purge config command only if there are named export queues that separate the replication streams for each one. Without named export queues, SharePlex funnels all replicated data through one export queue, and a purge config command for one configuration deletes the data for all of them. To create named queues, see Chapter 5 of the SharePlex Administrator’s Guide.

Syntax
| Basic command | Remote options |
|---|---|
| purge config filename |
[ on host | on host:portnumber | on login/password@host | on login/password@host:portnumber ] |
Syntax description
| Component | Description |
|---|---|
| filename |
The name of the configuration that you want to purge. Configuration names are case-sensitive. Example: sp_ctrl(sysA)> purge config sales |
Remote options
These options enable you to issue the command on a remote machine and to script commands that include a login name, password, port number, or combination of those items.
| Option | Description |
|---|---|
| on host |
Execute the command on a remote system (one other than the one where the current sp_ctrl session is running). You are prompted for login credentials for the remote system. If used, must be the last component of the command syntax. Example: sp_ctrl(sysB)>status on SysA |
| on host:portnumber |
Execute the command on a remote system when a remote login and port number must be provided. If used, must be the last component of the command syntax. Example: sp_ctrl(sysB)>status on SysA:8304 |
| on login/password@host |
Execute the command on a remote system when a remote login, password, and host name must be provided. If used, must be the last component of the command syntax. Example: sp_ctrl(sysB)>status on john/spot5489@SysA |
| on login/password@host:portnumber |
Execute the command on a remote system when a remote login, password, host name, and port number must be provided. If used, must be the last component of the command syntax. Example: sp_ctrl(sysB)>status on john/spot5489@SysA:8304 |
