Upgrade of Oracle Extension

mn_24 — Wed, 11 Jun 2025 14:22:34 GMT

Hello,

we've upgraded the Oracle Extension from 3.3.3 to 3.5.0.

Because we didn't want to receive any incidents during this activity , we've created an Automatic TAG and a Maintenance Window with a timeframe of 1 hour. Unfortunately we have received a couple of (not from each database) incidents not only in Dynatrace but also transfered in ServiceNow. Could anyone clarify - why this had happened?

Hi,

I think maintenance window scope was not defined correctly. I would review which entities were defined in maintenance window and which entities have that tag.

Best regards

Hi Anton,

I have just added some screenshots. But I checked and I am sure that the TAG was on each oracle process group.

You probably got problems about Oracle instance entities, if you had enabled some metric events based on extension data. You need to tag Oracle instances with your tag as well f.e. with this rule:

Hi,

yes, as I thought using the Process groups will work but in fact in my case when I changed the logic and used "CUSTOM_DEVICES where Custom device port equals 1521" all worked as expected.
