I looked some also and I think this is 120 seconds I am basing this on the file. ./iwc/tomcat/webapps/iwc/WEB-INF/classes/properties/iwc-config.properties
I am asking questions on this however as this file is outside the normal ignite_config folder that doesn't get over written on upgrades so I think a change here wouldn't keep on upgrade.
I was looking for a number of characters, not a number of seconds. I'm interested in maximizing the amount of information I can stuff in there. In the project I'm currently working on, that would be msdb.dbo.sysjobhistory.message, which is defined as NVARCHAR(4000). I have to truncate it to 425 in the alert, but that loses a lot of valuable information that I'd like to include in the email generated by the alert.
I found an old email thread that provides an answer but I'm not sure it's complete:
From: Jonathan Shaulis:
When the results are placed into the CON_ALERT_DB_RESULTS table, the NAME column is only 425 characters, so the field is restricted as such.
In hunting around, I think CON_ALERT_HISTORY_RESULTS.PARAMETERNAME also needs to be taken into account, which is also 425 characters.
NAME is part of a PK which also contains two SMALLINT columns which take up 2 bytes each. SQL Server limits a PK to 900 bytes, so NAME could be expanded to a VARCHAR(896).
PARAMETERNAME is also part of a PK, which contains a BIGINT which takes up 8 bytes. So PARAMETERNAME could be expanded to VARCHAR(892).
What horrible things might happen in DPA if I were to expand both columns to 892?
m60freeman Sorry I meant to update this before. Things got busy. I did some looking and want to confirm the location of the config and how this all works before adding details.
