n is an integer in the range 10—10,000. The default value is 500.
errlog is the maximum number of entries in the InterSystems IRIS® data platform system error log (see InterSystems IRIS System Error Log in the “Monitoring InterSystems IRIS Using the Management Portal” chapter in Monitoring Guide for more information). The log file expires old entries as this limit is reached.
Changing This Parameter
On the Advanced Memory page of the Management Portal (System Administration > Configuration > Additional Settings > Advanced Memory), in the errlog row, select Edit. Enter a number of entries.
Instead of using the Management Portal, you can change errlog in the Config.config class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
