AWR Warehouse

Database Comparisons with AWR Warehouse- Part II, Comparison Period Report

There are two ways to compare one database to another in the AWR Warehouse.

Database Comparisons Using AWR Warehouse Part 1- ADDM Comparison

A lot of my ideas for blog posts come from questions emailed to me or asked via Twitter.  Today’s blog is no different, as I was asked by someone in the community what the best method of comparing databases using features within AWR when migrating from one host and OS to another.

AWR Warehouse Fails on Upload- No New Snapshots

This issue can be seen in either EM12c or EM13c AWR Warehouse environments.  It occurs when there is a outage on the AWR Warehouse and/or the source database that is to upload to it.

AWR Warehouse Jobs in EM13c

As I’m playing with the AWR Warehouse in EM13c, I noticed a few changes that may send up a red flag and wanted to assist in removing those.  As many know, the AWR Warehouse is very dependent upon EM Jobs…even more so now that we’ve moved to EM13c.

Re-Adding a Database to the AWR Warehouse Without Losing Historical Snapshots

There may be a reason that one needs to re-add a database to the AWR Warehouse.  This is a new opportunity for me to learn and offer assistance, but I’m working off the grid to figure out a solution.  Luckily, it’s just a matter of creating a new process from pre-existing code and processes.

ASH Data and How Sizing an AWR Warehouse Can be Mitigated

When sizing the AWR Warehouse, one of my requirements is to have certain reports for a sampling of databases that will source the AWR Warehouse. This report provides me the right information to create the correct sizing requirements vs. any assumptions done with other choices.

Kickstarting After a Failed Addition to the AWR Warehouse

A common issue I’ve noted are dump files generated from the AWR Warehouse, but upon failure to transfer, the dumpfiles simply exist, never upload and the data is stuck in a “limbo” state between the source database, (target) and the AWR Warehouse.

SQLd360 with the AWR Warehouse

Mauro decided to give me another challenge-  run SQLd360 against the AWR Warehouse and let him know how it does straight “out of the box”.  It’s a simpler installation process than SQLTXPLAIN, you simply unzip and run, (no installation of any packages…)

I chose a SQL_ID from one of the source databases loaded and ran it for a 31 day history:

SQLTXPLAIN and the AWR Warehouse- Part II

I finally have a moment to look into my “hacked” SQLT XPRECT/XTRACT runs and see if the changes I made were enough to run properly with the AWR Warehouse.

The answer is yes and no… and maybe “it depends”… :)

SQLTXPLAIN and the AWR Warehouse, Part I

Yeah, so I did it-  I installed SQLTXPLAIN, (SQLT) on the AWR Warehouse!
