Introduction:

This document explains how to control the duration the WAAE Scheduler takes to either rollover to single Event Server mode or shutdown (when it's already in single Event Server mode).

Question:

What is the WAAE Scheduler database re-connection attempt interval when the Event Server is unavailable? Is it configurable?

Environment:

CA Workload Automation AE 11.0 SPX, 11.3.x on supported platforms

Answer:

The Scheduler retries connection to an unresponsive database at 60 seconds interval. This interval is not configurable. However, the number of connection attempts can be configured to increase or shorten the duration of reconnect attempts and database rollover (in dual event server mode) or WAAE instance shutdown (in case of Single event server mode).

The DBEventReconnect parameter in the $AUTOUSER/config.$AUTOSERV file on Unix/Linux (Event Reconnect field on the Event Server - CA Workload Automation AE Administrator GUI, on Windows) controls the number of times the Scheduler or Application Server tries to reconnect to the database before shutting down or rolling over to single event server mode.

The default values are, 50 in single event server mode and 50,5 in dual event server mode. Meaning, in single event server mode, the Scheduler tries to connect to the event server 50 times before shutting down and in dual event server mode, the Scheduler tries to connect to the event server (that is not responding) 5 times before switching over to single event server mode.

In summary, the default duration is:

In single event server mode: 50 (retries) X 60 (seconds), before shutting down.
In dual event server mode: 5 (retries) X 60 (seconds), before rolling over to single event server mode.

Note: Terms "database" and "Event server" are interchangeable for the purpose of this document.
