Oracle Database Express Edition Licensing Information

I figured out that Resource Manager Feature is not enabled in Oracle Express Edition (XE).

I write this information here, because I could not have found any feature list whether XE supports Resource Manager feature at first.

In order to understand, if XE supports, I tried to create resource plan and resource plan directive and I got the below error.

BEGIN

SYS.DBMS_RESOURCE_MANAGER.clear_pending_area();
SYS.DBMS_RESOURCE_MANAGER.create_pending_area();

SYS.DBMS_RESOURCE_MANAGER.create_plan(
plan=>'sample',
comment=>'');

SYS.DBMS_RESOURCE_MANAGER.submit_pending_area();

END;
/

ORA-00439: feature not enabled: Database resource manager

ORA-06512: at "SYS.DBMS_RMIN", line 63
ORA-06512: at "SYS.DBMS_RESOURCE_MANAGER", line 111
ORA-06512: at line 5

Further, internal resource plan is enabled:

select * from v$rsrc_plan;

ID NAME IS_TO CPU INS PARALLEL_SERVERS_ACTIVE PARALLEL_SERVERS_TOTAL PARALLEL_EXECUTION_MANAGED
--------- -------------------------------- ----- --- --- ----------------------- ---------------------- --------------------------------
1 INTERNAL_PLAN_XE TRUE ON OFF 0 0 OFF

After googling around, I found that full feature list supported could have been found from below document:

Oracle Database Express Edition Licensing Information

http://docs.oracle.com/cd/E17781_01/license.112/e18068/toc.htm

So I will look for Licensing Information of any release from now on.

Your team could have possession of the ball but you never know when that possession will be lost and your team
must transition to defense. Winning is obviously the name of the game in big-time college football, but Saban and his teams focus on the process.

Football is definitely a sport that requires a combination of skills and athletic ability.
