Part1 Configuration Evodesk

Installation was not bad.

Evodesk is the 2nd company I am aware of for using recesss nuts for desktop installation.

This makes much more sense than using wood screws.

However, pondering if Evodeskk will be the first company to used recess nuts for all components and get rid of wood screws.

Don’t you think the legs make  great towel rack?



First Impression for Evodesk Desktop Unboxing

Disclaimer: I am not being paid by anyone to write positive or negative review.

Opinions are my own based on my limited engineering background.

First, packaging is somewhat poor and could be much better for a desk costing close to $1,000 ($886 for my configuration).

Tape coming off.


I hope my desktop is okay.


Taking a look inside. Is that a tiny scratch I see?


After opening the desktop, this is the torn location – (more...)

Backup file using copy with date append

How many ways are there to backup a file? Copy and append .bak, .sav, .orig, etc …

I was looking for a simple, yet elegant way to do this.

Good thing for Google (disclaimer I do own the stock), I came across this blog –

In Search of Standing Desk

I came across Evodesk Standing Desk Review

Could not resist the temptation but reach out to @TreadmillDesker
You bark loud but how is ThermoDesk ELITE better EVODESK other than motor? $477=1333-886 is a lot for a motor. Let’s see pic.

Here is the respond I got back.
Thanks for the question! lab test of the Evo’s base concluded: slower speed, louder motors, and instability at taller heights.

Find Users with DBA Roles

This sounds like a simple request doesn’t it?

Simple if there are no roles which are granted DBA role and allow me to show what can go wrong.

Create ROLE “secret”, Grant DBA to “secret”, Grant “secret” to USER “michael”

ARROW:(SYS@hawklas):PRIMARY> create role secret;

Role created.

ARROW:(SYS@hawklas):PRIMARY> grant dba to secret;

Grant succeeded.

ARROW:(SYS@hawklas):PRIMARY> grant secret to michael identified by michael;

Grant succeeded.


When a simple SQL is used, “secret” is a ROLE NOT USER.

restore validate archivelog

A common mistake I see in backup validation is not validating archivelog or Level 1 backup.

Here I will demonstrate various methods to validate achivelog.

Validate archivelog and does not list details for archivelog backup set. Too little information?

RMAN> restore validate archivelog from time “TO_DATE(‘2015-MAR-04 22:03:32′,’YYYY-MON-DD HH24:MI:SS’)”;

RMAN-06023: no backup or copy of datafile # found to restore

There’s a great note from MOS – Checklist for an RMAN Restore (Doc ID 1554636.1) but how many of you review this before performing a restore?

If you don’t then you are as guilty as I am.

Oracle Manual Standby – Applying Log

If you are running Oracle EE, there are many books on Data Guard. However, for Oracle SE and manual standby, have fun searching.

I wanted to get a better understanding of registering logfile.

Depending on how the standby environment is monitored, not registering logfile may yield incorrect results when checking standby lag.

When logfile is not registered, v$archived_log is not updated.
