Fixed issues in DPA 2021.1.872
DPA 2021.1.872 fixes the following issues.
|00748237||DPA does not display new feature teasers when the advanced option
|00747082||DPA monitoring for PostgreSQL databases no longer fails to start if the DPA polling query returns empty rows. If the query returns empty rows, DPA logs a warning about the statistics that cannot be collected, but basic monitoring continues.|
|In certain situations, when users attempted to restart monitoring on a large number of database instances, monitoring would fail to start and DPA would log messages such as "Task has been rejected by TaskExecutor." This issue has been resolved.|
|DPA cannot monitor a PostgreSQL database instance with multiple connection properties|
Issue: If you enter multiple connection properties in the JDBC URL field (either in the Registration Wizard or the Update DB Instance Connection Wizard) for a PostgreSQL database instance, DPA cannot monitor the instance. DPA repeatedly attempts to start monitoring the instance, but monitoring fails to start.
Resolution/Work-around: Change the property separator in the
|Creating the repository user when creating a MySQL 8.0 repository database|
Issue: For MySQL 8.0, the default authentication plug-in has changed from
|Alerts stop working after a database instance display name is changed|
Issue: If you include a database instance in an alert and then change the display name of the database instance, the alert stops working for that instance and emails are not sent. Even though the instance name appears to be updated in the alert definition, it is not updated on the Alert Status tab.
Resolution/Work-around: Open the alert definition and save it again, without making any changes. Saving the alert definition updates the name on the Alert Status tab.
|Validation of the LDAP/AD server host name fails because it doesn't match the subject of the certificate|
Issue: Java validates that the host name of the LDAP server matches the LDAP certificate by checking the subjectAlternativeName's dNSName fields of the certificate. If the validation fails, you will see the following error when you are configuring DPA to use AD/LDAP:
|Resolution/Work-around: Follow the instructions in this article to resolve the issue.|
|Adding a distributed AG to a server prevents DPA from monitoring non-distributed AGs on the server|
Issue: If DPA is monitoring non-distributed SQL Server Availability Groups (AGs) on a server and you add a distributed AG to the server, DPA stops monitoring the non-distributed AGs.
|Resolution/Work-around: Do not add a distributed AG to the server.|
|Microsoft reports incorrect metric values for SQL Server on Linux|
Issue: When you monitor a SQL Server 2017 database instance that runs on a Linux server:
When you monitor a SQL Server 2019 database instance that runs on a Linux server:
Microsoft reports these values.
|Resolution/Work-around: Disregard the values that are incorrect on your version of SQL Server. Upgrade to SQL Server 2019 to resolve the issue for the Instance CPU Utilization and O/S Memory Utilization resources.|
|Monitoring a database instance in the Oracle Public Cloud|
|Issue: When DPA is monitoring a database instance in the Oracle Public Cloud, it sometimes reports incorrect values.|
|Resolution/Work-around: DPA does not support monitoring database instances deployed in the Oracle Public Cloud. Use DPA to monitor supported database instance types.|
|Creating the monitoring user when registering a MySQL 8.0 database instance|
Issue: For MySQL 8.0, the default authentication plug-in has changed from
