Issue/Introduction

Currently Alert Central hasn't a High Availability feature. How to not lose alerts for example in case the Alert Central(on Linux) needs to be upgraded or reconfigured? 

Resolution

For such a scenario 3 parms needs to be configured to allow the Alert Central Connector(ACC) to hold alerts while AC is off. 

MaxRequests - maximum number of requests, for all users, that can be queued.

MaxUserRequests - maximum number of requests, for a single user, that can be queued.

RequestTimeout - maximum time that a request can be queued.

 

All three parameters can be dynamically modified via a 'F accproc,SET.ACC' command.

 

Default values are 1000, 100, and 120 (seconds) respectively. In addition, the requester can specify a shorter timeout value on each individual request.
