Internet Explorer 10 crashing randomly on Windows Server 2012 when using EAC on Exchange 2013

I did notice recently that after having installed and configured Exchange 2013 on Windows 2012 Standard, sucessfully, IE 10 starts acting weird each time I try to work on EAC (Exchange Admin Centre) using this browser.

From other other blogs and posts that have suggested different work arounds, I found downloading and installing the following security patch to be the best. You may either visit the Microsoft website and download the patch or waste no time and download it directly from here. I did not have any issues thereafter. However, you can still browse the EAC page from your laptop or PC with Windows 8 installed and use the IE 10 on it.

Setup Multiple Log Archive Destinations for your Oracle Database

Applies to Oracle 10g and above

I would assume your database is already in the ARCHIVELOG mode

SQL> show parameter LOG_ARCHIVE_DEST

This would show all your Archive Log Destinations without any value unless previously set. It would be wise to set multiple Archive Log Destinations on alternate physical disks. It would prevent the database to stop functioning if the first destination disk is full.


The LOCATION keyword is used to define that the destination is local; for remote destinations use the keyword SERVICE

SQL> alter system set LOG_ARCHIVE_DEST_2='SERVICE=yournetworkservicename'

Oracle 11g – Enterprise Manager does not start – Windows

At the command line; check if the listener is started and running correctly

lsnrctl status

Stop and restart the listener based on listener status

lsnrctl stop
lsnrctl start

Use the Enterprise Manager command to check the status of the Database Console

emctl status dbconsole

If you get an error “Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name”, please below command to set it accordingly

set ORACLE_UNQNAME=<dbname>
e.g:  set ORACLE_UNQNAME=orcl

If the dbconsole is already started and active, please restart the dbconsole with below commands

emctl stop dbconsole
emctl start dbconsole

Check the status of the console once again

emctl status dbconsole

You should now ideally be able to access the Enterprise Manager
