In Oracle Enterprise Manager (OEM) there is the ability to host an AWR Data Warehouse which enables you consolidate all your detailed performance data of all your database and store in a central location.
This enables you to do long-term analysis trend across your AWR data to determine, performance, capacity impact on the databases in your IT estate.
In OEM 13.5, Oracle now supports the AWR Warehouse repository for Autonomous Data Warehouse.
If you don’t have the infrastructure or capacity to store AWR data on-premise, you can now send your data to the Autonomous Data Warehouse(ADW) in Oracle Cloud (OCI).
There are enormous benefits to using Autonomous Data Warehouse(ADW). One of many benefits is that you can scale up/down cpu and storage whilst the database remains online.
Logs are often voluminous can be challenging to navigate through, but it can be a gold mine of valuable data to help administrators troubleshoot and identify issues or trends for operational activities.
To overcome the burden of manually eye-balling millions or (even billions) of rows in log records, bringing that data into OCI Logging Analytics(which is part of the Observability & Manageability Portfolio) will allow administrators to get quick insights, to reduce the time to isolate issues, minimising downtime and prevent impact to end users.
I recently had a requirement where the Common User in a Multitenant DB environment wanted to access application tables across Pluggable Databases (PDBs) but at the same time access dictionary views across all PDBs without the need to manually switch between containers.
This was because I had to setup a monitoring user account to monitor all PDBs performance as well as application workload.
In this example I will show you how the Common User (created at CDB level) can be configured to access the application tables (create at PDB level)
