I gather this is not part of CRS stack.
I did a check on our 2 node RAC . It showed

The command "crsctl check/start/stop/disable/enable has" is to be used only when you configured Oracle Restart (i.e Grid Infrastructure for a Standalone Server)
Oracle Restart Environment CRSCTL Commands
http://docs.oracle.com/cd/E11882_01/rac.112/e16794/crsref.htm#CHDBIAAE
If you have Oracle Clusterware (i.e Grid Infrastrucutre for a Cluster) installed/configured you must use the command "crsctl start/stop/check/enable/disable crs"
The OHAS was introduced on Grid Infrastructure as new feature of architecture of Grid Infrastructure.
Oracle Clusterware consists of two separate stacks: an upper stack anchored by the Cluster Ready Services (CRS) daemon (crsd) and a lower stack anchored by the Oracle High Availability Services daemon (ohasd). These two stacks have several processes that facilitate cluster operations.
http://docs.oracle.com/cd/E11882_01/rac.112/e16794/intro.htm#CJHECEDD
In Oracle Restart envorimment the OHAS is also is avaliable but with less processes involved.
So for this reason there a difference between "crsctl ... has" and "crsctl ... crs". Each command must be used on correct environment.

How do I know how many JFrames has opened ?

Hi,
I've got an application which has a main form (JFrame).
Inside this main form there are buttons which opens others JFrames.
When I close the main form I need to show how many others Jframes has opened.

Can someone help me, please ?

How important is gathering statistics on SYS objects?

Hi,
How important is gathering statistics on Data dictionary tables and other X$ tables in SYS schema. Is it bad to keep the statistics. Recently our Sr.DBA has deleted all the SYS schema stats telling that it will inversely affect the DB performance. Is it true?
Regards
Satish

Hi Satish,
*10g:*
A new DBA task in Oracle Database 10g is to generate statistics on data dictionary objects which are contained in the SYS schema. The stored procedures dbms_stats.gather_database_stats and dbms_stats.gather_schema_stats can be used to gather the SYS schema stats. Here is an example of using dbms_stats.gather_schema_stats to gather data dictionary statistics:
EXEC dbms_stats.gather_schema_stats(’SYS’);
*9i*
While it is supported in 9.2 to gather statistics on the data dictionary and fixed views, doing so isn't the norm.
There is a bug fixed only in 10gR2 (not expected to be back-ported to 9.2) that caused this error. The fix is – don’t generate statistics against SYS – especially not the Fixed tables.
For this query, let's see if we can get a better plan by removing statistics or by getting better statistics, or if we need to do something else to tune it. Take the SYS statistics as before, but with gather_fixed => false.
I would like for you to test first by deleting the statistics on these two X$ tables and see how the query runs (elapsed time, plan).
delete_table_stats('SYS','X$KQLFXPL');
delete_table_stats('SYS','X$KGLOB');
Then you can take statistics on them using gather_table_stats and check again (elapsed time, plan).
gather_table_stats('SYS','X$KQLFXPL');
gather_table_stats('SYS','X$KGLOB');
The issue with this is that the contents of these fixed views, particularly x$kqlfxpl, can change dramatically. Gathering fixed object statistics may help now and cause problems later as the contents change.
Warning, this is a bit dangerous due to latch contention, see the following note. I've supported a couple of very busy systems that were completely halted for a time due to latch contention on x$kglob due to monitoring queries (particularly on v$open_cursors).
Note.4339128.8 Ext/Pub Bug 4339128 - Heavy latch contention from queries against library cache views.
Hope this answers your question . . .

If you are the only one to use the MacBook you don't really need an administrative password. The main use for it is to stop other users from accessing and making changes on the Macbook.

JDev : No accelerator for import assistance has been defined

Hi,
I am using JDeveloper 11g (11.1.1.6.0) but import assistance is not working and its saying "*No accelerator for import assistance has been defined*". I am on Windows 8 64 bit OS. Do we know how to fix it ?
Thanks,
Abhi

Well, you can remove or rename the system11.1.1.x.x.x folder which hold all properties. Next time you start jdev the folder is recreated with default settings. All your changes are lost.

How important is to have an Oracle Certification?

Hello,
I would like to have your opinion on
How important is to have an Oracle Certification?
Thank you.

I still think certification is more of a personal decision than a professional one.
Back in the day, it was pretty much only Novell who had a certification programme. Then companies like Oracle realized it was a good vehicle to sell more training. Imagine money being a motivating factor! Shock!
Since then, certification has gained more of a foot hold within our industry, but I agree with other posters that experience and working knowledge is far more important.
I started my Oracle DBA certification 'career' back in '99 with 7.3 and have become certified in every release since then, up to and including 10g. I will get my 11g too when the time comes. The reason I have done this is purely for personal satisfaction. Having been an Oracle DBA for some 18 years now, I cannot justify NOT doing the exams. If I really do know what I'm doing, then taking an exam shouldn't really be too much of an issue. Plus, studying for an exam forces me to get acquainted with all the new features which should make me a more knowledgeable DBA.
Having said that, I've interviewed certified DBAs and have found worrying gaps in their knowledge. Personally I don't think the DBA upgrade exams are that difficult. I always finish well within the time allowed and score in the 80% to 90%+ range every time. In fact, I completed my 7.3 to 8.0 upgrade exam in 22 minutes. No I'm not a genius so judge for yourself how difficult that exam was.
Over time certification may become more and more relevant as an initial screen, but DBAing is such a vast and complex area that no multiple choice exam can accurately assess your depth of knowledge.
One final point, I do think Oracle themselves de-values the DBA certification by offering two certifications in one exam. For example, 8i certified DBAs can get 10g certification by passing ONE exam. I think that's wrong. If you missed 9i, then you should be made to go back and get it first - no short cuts. Just my opinion.
So, bottom line. If you're relatively new to DBAing, then go get certified. It's something else to put on your resume and shows you got off your butt and worked for it. If you're an experienced DBA, what's your excuse for not doing it? Scared you'd fail? ;-)

Hi. I have an iPhone 4 and no data plan. When I'm not connected to wifi I don't receive iMessages, but later when I do connect to wifi, I get them telling me they were sent earlier. I don't remember how long this has been happening. Any Help?

Hi. I have an iPhone 4 with iOS7 and no data plan. When I am not connect to wifi I don't receive iMessages, but then when I do connect to wifi I get the messages telling me they were sent earlier. Is there any thing I can do to fix it? I don't remember how long this has been happening but it is very frustrating. Any suggestions would be great! Thanks!!!

If you don't have a cellular data plan, then why are you expecting that you will have an active internet connection unless you are connected to wi-fi?
iMessages require either wi-fi or a cellular data connection.

How many pins has my Mini DisplayPort ? 32 or 20 ? I have a late 2009 MBPro 13" (Impossible to find this answer online!)

How many pins has my Mini DisplayPort ? 32 or 20 ? I have a late 2009 MBPro 13" (Impossible to find this answer online!)

Thanks - that's what I am worried about.
The 2010 MBPro is a different version when it comes to the Mini DisplayPort because the 2009 MBPro doesn't transmit audio ony video whilst the 2010 MBPro does both.

How important is using optical audio, since no surround?

I'm out of optical inputs on my A/V receiver. How important is using the digital optical audio output, since there is no surround sound on the Apple TV?
Is using analog audio cables that bad, since the content on Apple TV is stereo to begin with?
Thanks for the help.

I don't think the issue will be surround sound since surround sound isn't supported by the tv, although as capaho points out there are some files floating around out there that appear to work with the tv, however as far as I know these are all test files and there isn't actually any content as such available.
The issue for you will be one of quality, which of course means different things to different people. Personally I can only tell the difference between analogue and digital sound on some tunes and my personal taste in music does not always include those tunes (more of a Rolling Stones listener than Debussy) , so I'm quite happy to use analogue audio for my set up. Whether you are happy to do so will be one of personal taste.

How important is it to have non-flash content for iPAD?

Hi there.
I'm busy building a site with an image rotater in the header with a couple of images from the products. This rotater works with flash which does not work with iPAD. How important do you rate it to definitely have non-flash content as to have the odd cosmetic slide show here and there?
Regards,
Deon

Wonder why iOS does not like flash?
Hi
On Android devices the reason given for dropping support, (or no support in the case of iOS) was because it was literally possible to watch the battery power indicator drop whilst watching anything that required flash.
On a Samsung Galaxy it only required 7 minutes of Flash video to drain the battery, and on an Android budget tablet I also use for testing, (sub £150) 3 minutes.

You first convert them to ProRes with Compressor or MPEG STREAMCLIP, then import the ProRes files into FCP. FCP doesn't work with the AVI container...footage must be Quicktime, and must be in a codec FCP works with.

Is there a timer app for tracking how long someone has been logged on?

I want to limit my child's total screen time on a daily basis and display how long he has been logged on. This is different from time limits, which set the start and end time of the day.

Aaaah ... I found that setting now. Thank you.
This may do the trick.
I suspect the app developer is a non-English speaker. The support page is on Japanese and there is no reference to the calendar functionality in the store description. It looked like an Evernote-only add-in. I never would have found it without you. Thanks again.
