Hi,

What is a command that will clear all data from queue on replication server?
I know that it exists but I don't remember how it goes :/

So I will reply myself:

Purges all messages from a stable queue.
Syntax:
sysadmin sqm_purge_queue, q_number, q_type

Parameters:
q_number, q_type

Identifies the stable queue to be purged. Find these using admin who, admin who, sqm, or admin who, sqt.

Example:

Purges all messages from inbound queue number 103:

sysadmin sqm_purge_queue, 103, 1
