How did I come to the ALTER USER RENAME command? Just a lucky punch due to my customer. My customer were trying to rename an user in an Oracle Database with several objects (tables, view, functions, types and so) by simply updating the sys.user$ table :-) The result were better than (more...)
Many times DBA's have to rename / copy complete users/schemas from the current name to a new name within one database. Since several years DBA's are asking for a simple method inside Oracle to execute something like "ALTER USER RENAME".

As everybody already know that the latest version of Oracle Enterprise Manager 13c (184.108.40.206) has been released yesterday (see also my post from 18th December 2015), Oracle has uploaded several interesting presentations around the new Oracle Enterprise Manager 13c.

The enhancements are really impressive, you are able to monitor (GET) or to modify (POST) your WebLogic environment in detail with a simple URL call either via Browser or via Command Line Tools like cURL.

Within the new release of Oracle WebLogic Server 12.2.1 is a really cool new feature for Data Source System Properties.
In case you have mutliple data sources defined within your Oracle WebLogic Server pointing to the same Oracle Database and mostly using the same Oracle Database user, you have currently limited chances to identify in your v$session, which session belongs to which WebLogic Server Data Source.
Normally end users would like to have a simple URL access for Oracle Business Intelligence Enterprise Edition (OBIEE) 11g like http://webhost:7777 and than to be automatically redirected to their Dashboard, instead of typing endless complex URL's.
Assuming you have following standard implementation of an OBIEE environment which contains an Oracle HTTP Server (OHS) configured with mod_wl_ohs to be proxied to point to your WebLogic Server hosting OBIEE and an OBIEE Server, you can simply use (more...)
