ORA-16792 configuration property value is inconsistent with database setting

As per the reference this error literally means:

Cause: The values of one or more configuration properties were inconsistent with database in-memory settings or server parameter file settings. This may happen by altering initialization parameters directly instead of altering property values using Data Guard broker.

Actions: Query property the InconsistentProperties on the database or check the Data Guard broker log to find which properties are set inconsistently. Reset these properties to make them consistent with the database settings. Alternatively, enable the database or the entire configuration to allow the configuration property settings to be propagated to to the initialization parameters.

When the dataguard broker was queried about the status, it showed the following results:

The parameter involved in this particular case was  db_file_name_convert, the paths defined at the spfile were different from those known to the Dataguard Broker. db_file_name_convert is a static parameter which means the standby database had to be restarted so the parameter was effective.  The actual actions that took place to solve this issue were to set the parameter at the database level and modify the value at the dgmgrl prompt.

Step 1. Modify the instance parameter.

alter system set db_file_name_convert='C:\Oracle11g\Oradata\OMCPro', 'J:\Oracle11g\Oradata\OMCDG', 'D:\Oracle\Oradata\OMCPro', 'D:\Oracle\Oradata\OMCDG' scope=spfile;

Step 2. Modify the parameter at the DGMgrl prompt

C:\> dgmgrl

DGMGRL> edit DATABASE "OMCADG" SET PROPERTY DbFileNameConvert = 'C:\Oracle11g\Oradata\OMCPro, J:\Oracle11g\Oradata\OMCDG, D:\Oracle\Oradata\OMCPro, D:\Oracle\Oradata\OMCDG' ;

Property "dbfilenameconvert" updated

Once the parameter is consistent both at the spfile and the Dataguard broker it updates its status to SUCCESS.

Flash Player 11.3 kept crashing with Firefox 13.01

The browser I use the most is Firefox, a personal reason that started back at the time when the way to avoid internet worms from infecting the computer was to either endlessly keep on updating the I.E. or by using low maintenance reliable browser.  Ever since Firefox became my preferred choice.

Recently something weird happened, one of those auto updates that bring down the system and ask for restart of applications, and suddenly  my Firefox stopped displaying the Enterprise Manager performance graphs. I had to temporarily switch to Internet Explorer while I was able to find a solution for it.  The funny thing is that it only replied with a kind of progress bar that read RSL Error 1 of 3 or RSL Error 2 of 3 and a small caps error message at the bottom of the display where the graph was supposed to be shown that read Error #2032.  Nothing else ... so after a long Google search that lasted the whole morning, digging for a clue on what was going on  I finally came up with a diagnostics and a possible solution.

Every time I tried to load a page with flash player contents it crashed, and in the case of YouTube it just mentioned the contents couldn't be played at this time and it asked to retry later (some sort of insanity, it doesn't matter how many times I'd have tried nor how later I'd retried the result would have been always the same). So none of the contents that required the flash player plugin could be played.

The solution was found in this Firefox support article "Flash 11.3 doesn't load video in Firefox"
I had installed the Real Player and the feature to download and save flash contents was making the Flash 11.3 plugin to crash.  The solution, just as it was described in the above article was to start the RealPlayer and from the main menu / Preferences / Download & Recording submenu, I unchecked the "Enable web download & recording for these installed browsers" option.  I restarted Firefox and everything came back to normal.  Since this is my work machine, I'm not too much worried about not being able to download my favorite videos by means of the Realplayer plugin.  I'm much more concerned about being able to display my Performance graphs and accessing the flash version of My Oracle Support.
