Launch chrome on a windows remote desktop

At work we often need to connect remotely to customer machine to give support. On one of this machines we share a single windows user, which can be connected on several remote desktop session at the same time.

In this situation it could happen that you double click the chrome icon on the desktop and nothing happens.

I tried to search the internet about this problem and find this (useful) link

The problem depends on the fact that we are using the same profile data on several sessions (more or less) and the solution is to launch chrome with several command line parameters.

So I have putted this line:

chrome.exe --user-data-dir=%LOCALAPPDATA%\Google\Chrome\%CLIENTNAME%

in a .bat file and created a shortcut on the desktop for it.

Hope it can be useful to someone else!

Oracle error ORA-04023

ORA-04023: Object could not be validated or authorized

This error suddendly showed up this week at work, while a collegue of mine was working on one of our dev databases. It was raised during a view compilation.

Since the view was joining tables and/or views from a couple of different schemas I checked the related grants and they were all ok.

Not finding any clues I searched metalink, and quickly discovered the doc. id 1610514.1 whose title is, meaningfully:

"Ora-04023 Reported while Accessing Valid Objects"

It states that the cause is:

This is issue is due to a timestamp inconsistency in the data dictionary. This timestamp inconsistency will lead to the problem when we populate the relevant cached objects and later try to select from the affected views

Nothing is told about the root cause of this problem, but at least it was a known one..

To solve the doc prescribes to run (as SYS) the script

utldtchk.sql

from the admin folder. This script extract objects affected by this "timestamp inconsistency".

Recompiling all of them eventually solved the problem.
