How do i monitor the health of my Raid array?

First, I want to thank Harm, Bill, and all the countless others who continue to give great advice on this forum. My question is how to I monitor the health of my raid array and how to determine which disk is acting up. I am using a 3-disk soft raid 0 off my motherboard (gigabyte ud3p). Seems to work pretty well but occasionally has a hiccup in certain programs. I wonder if it is a sign of an impending problem or if it is just because it is a soft raid. I've tried several HD diagnostics (Crystal Disk Info, Active@, HD Tune, etc.) but aside from temperature, they don't give any info about the impending death of my raid 0. I have the SMART feature turned on in bios.
To premtively address the critics about the raid 0. I only do about one video a week and do a backup every night. So i figured it (and when) it crashes, i'll just lose a days work. The motherboard is suppose to do a raid 5 but it performed really poorly. My system is configured with additional drives (SSD boot, Raid 0 scratch, and final video) as recommended. Any advice would be appreciated.

The problem with almost all raid controllers is that they do not support SMART. So that is out. With software raids you are even more limited.
With hardware raid controllers you have web based interfaces that show some basic information, like this:
but software raids do not. There are two ways to determine possible problems, at least that I know of:
1. Use drive cages with LED's for the individual drives to show activity and inspect them visually.
2. Use old-fashioned manual labour to feel vibrations, temperatures and hear clicks on individual drives.
With only 3 drives in the raid, the chances of guessing correctly are 33.3% to start with and they only increase with manual inspection. A far easier job than in the case of 6 or more disks.
Sorry I can not offer better suggestions.

How do I monitor the actual refresh of materialized view.

Hi See below,
I am creating the materialized view.
It took a while to see the actual data in the table. Do you any reason.
How do I, investigate, if there is any issue, how do I monitor the actual refresh.
I am worried since, it look long time to see the actual data, after creating the materialized view.

During the initial building of the materialized view, the data is not available to users until the refresh completes.
If you are talking about subsequent refreshes, you have a few options
- Can the materialized view be made fast refreshable?
- If not, can you put the materialized view be put into a refresh group? This will increase the time required to refresh, since Oracle would be deleting and inserting rather than truncating and inserting, but the old data will remain available for users until the refresh completes.
Note that the Replication or Database - General forums might be more appropriate for this sort of question. You may want to move further discussion to one of those forums.

How can I monitoring the usage of an index in oracle 8i

Dear Gurus,
I known the Oracle 9i have this new feature "Identifying Unused Indexes" via ALTER INDEX MONITORING USAGE, but how can I monitoring the index usage in the Oracle 8i?
Regars

You can't in 8i. However you can look at the SQL Text in the SGA looking for anything that matches the table name that the index is for and then look at the explain plan for the selects and updates. Pain in the xxx to do but it should give you the information.

How do i monitor the temperature

Hi, how do i monitore the temperature of my macbook C2D? what is the normal temp of the macbook?
Thanks

Many ways to see those numbers. I use the iStat pro widget:
http://www.apple.com/downloads/dashboard/status/istatpro.html
wich gives a lot of useful info. As for normal operating temperature, some macbooks run cooler than others. My temperature at idle (not start up) is in the low 50s (celsius). Fans start to ramp up in the low 60s, and won't let the temp climb up to more than, say, 78-80, under a very heavy work load.

How do I monitor the listener process

After starting the listener, I have to wait for few min. before I connect to the database.
Otherwise I get the following error.
How do I monitor the listener process and make sure, still it is trying to
establishing connection with oracle instance ?
thanks
siva

After starting the listener, I have to wait for few
min. before I connect to the database.That's normal when the registration is dynamic (no SID_LIST in listener.ora). This does not happen if the listener is started before the DB. See http://download-uk.oracle.com/docs/cd/B19306_01/network.102/b14212/architecture.htm#sthref429
But you can force the registration. As sysdba do
SQL> alter system register;
or you can statically configure your DB within listener.ora, SID_LIST section.

How do YOU track the health of your RH project?

Morning all,
I think I've recovered from my corrupt .fpj files from the recent time change. Thanks to Peter Grainge for bulldogging it for us. But it got me thinking about how I monitor (or don't) the health of my RH project. Just trying to be proactive here so that my first indication of something wrong isn't a heart-pounding "Oh %$#@^&*!, all my topics are gone!".
RH provides a ton of reports which are more or less useful depending on the features you've implemented in your project. And generating/publishing gives a total # of files that I like to watch.
But I'd like to hear from some RH veterans. Aside from exercising good backup management, what do you look at to gauge the health of your project?
Do you simply check the Broken Links report each morning as a sanity check?
Do you check the actual files in Windows Explorer?
Do you generate the project and test the end results?
Thanks for sharing.
Patrick

Going back to health tracking, daily source zips, even for projects in source control, are a good thing. How far back to keep them (my projects are a bit image-heavy, and weigh in at 40 and 60M respectively) is dependent on the amount of storage space I have and how many changes I'm making.
When I remember, which is not often enough, I save off a Used Files report for each project, labeled with the date. That shows files that have been lost from the project, but not deleted from Windows. A coworker has been comparing .fpj files in Excel to find lost folders and topics.
Does anybody else out there wish that the RH reports produced .csv files so that the resulting information can be more easily sortable? I'm putting in a Wish List request for that today. I know it's possible to extract information from the .cpd file with Access reports, but I can't do that right now (and frankly, I'm afraid to).

How do you fix the Health App from crashing?

If you put too many steps in the Health App, the Health App crashes and won't let you get back in it. How do you reset it, or fix it?

The Health app is a default app and cannot be deleted. Most of the data the Health app collects and stores is dependent on a third party app. If you don't install the third party app the Health app will not show that data. For those things that the Health app can collect, such as Steps, distance walked, etc., you can choose to not show those on the dashboard Of the Health app. Tap on an item in the Dashboard such as the Walking + Running Distance then turn off Show on Dashboard. I place all the apps I rarely use or never use in a folder called Seldom used. I place that folder on my last Home screen all by itself so I rarely even see the folder.

How can I monitor the voltage output sent to each servo axis programmatically?

Hi I am wondering if it is possible to monitor the voltage that's being sent to a servo motor during an axis position movement (in particular quantities such as max voltage). I am using a PID controller to drive this servo motor.
Thanks
Vlad

Hi Vlad,
Unfortunately, I don't think there is a way to programmatically read the voltage output to the drive, as the voltage is all determined internally by the controller circuitry on the board. Depending on the controller though, you may be able to physically route the output terminal to a spare analog input channel and read in the voltage that way. This example Analog Input with 73xx Motion Card shows you how to program LabVIEW to do this.

How does OEM monitor the weblogic domain

Hi Guys,
I would like to know how does the OEM monitor the weblogic domain, i.e where does the em agent (in the target host) check to determine if the weblogic domain is up or down ?
- Does OEM fetch data regarding managed server from admin server ?
- Does managed servers show up in OEM if the admin server console is down but the managed server is up ? (i think it does show up, even if the admin is down but then how/where does it get to know the status)
- Is there any settings in the weblogic to be set ?
- Does the behavior of weblogic EM console and the OEM grid console are same ?
Basically want to understand, how and what all needs to check when the domain is showing down in OEM (when domain is up and running in weblogic console and the agent is perfectly fine)
Similarly for the Database how does it check the status "up or down"
- does it try to make a connection to the db ?
- if so where do we give the details for the db connection user and password ?
Please help me in understanding these.
Thanks and Regards,
Harish

If the targets are actually up and showing down in OEM console , so it means something wrong with the configuration .
Can you check the error message in the console , why it is down ? Or you can also check agent logs on the target server.
To monitor the weblogic , it uses username used during the configuration.
Please check the picture at below link :
Discovering Middleware Targets
Enter the WebLogic Administration Server user name and password.If you want to discover the target only for monitoring purposes, then it is sufficient to provide a user name that has a monitoring role. If you want to monitor the target and also perform start/stop operations, then ensure that you provide a user name that has either an operator role or an administrator role.Note: There is the potential of account locking issues if you enter the default WebLogic user name, and the account password is changed without updating the Enterprise Manager monitoring credentials for the Domain and Farm.
Thanks
Rajesh

How to you stop the health app running in the background?

How to you stop the new Health App from running in the background? Its its always running collecting data on how many steps I have taken and how far I have walked.. I walked 12000 steps and travelled 4.1km DRIVING my kids to school this morning according to the app.

I never intend to use the health app because I do not need an app on my phone to help me live a healthy lifestyle. Therefore I find it intrusive there is no way to stop it from tracking my steps or whatever else it may be doing. I found a way to force the app to crash and maybe this will stop it from running in the background. Open the app, tap "Health Data" at the bottom of the screen, tap "Fitness" then "Steps" and tap "Add Data" type in a huge number - a very huge number with 30 or more characters, you can even add more than 1 decimal point. Repeat this for "walking + Running Distance". From this point forward the app will crash when you try to look at the data. Maye this prevents it from recording new data, I'm not sure but I really like the fact the app crashes. Hopefully Apple will add a feature to allow us to turn off data collection altogether or even better, allow us to delete this app.

How can I monitor the used memory

How to continuously monitor the values of a particular column in datagrid

I want to monitor the column
as for example the colour of the data changes
if it crosses a particular value and change back when the value
comes down.
updateComplete is not working here,I tried it.

Hi,
If you go to your VO and generate the ViewObjectImpl, in there you can create a method which will contain two parameters, 1 the attribute name and 2 the value.
Then you can follow something like explained in this post:
ADF Tutorial: How to apply bulk actions to a view object rows
The only difference is that you will need to create a method like this:
public void updateAttribute(String attribute, Integer value){
        RowSetIterator iter = createRowSetIterator(null);
        while (iter.hasNext()){
            Row row = iter.next();
            row.setAttribute(attribute, value);
Then you expose that as a client interface and then after you filter your table by your criteria you just need to execute this method passing the right parameters.
Regards

How Can I Test The Health of my Mac?

Hello, I have a Mid-2012 13 inch MacBook Pro with 2.5 GHz, and an Intel Core i5 processor. I got this Mac about 14 months ago for Grade 8 high school work purposes (I'm in a special Digital Immersion program where all work is done on Macs). My Mac's performance and speed while using OS X has started to decline over the past few months, in a slow and gradual manner. I am not sure if this is something that I should be worried of, or not. I have 186 GB free from my 400 GB Mac OS X Mavericks partition, and 54 GB free out of 100 in my Windows partition. I use my Mac quite heavily for things like video editing with Final Cut Pro, photo editing with Photoshop, word processing, surfing the web, and the occasional game on Steam. I want to test the health of my computer to ensure it is okay. I used a Geekbench test and found with a single core my score is 2576, and with multi core 5177. The closest model I have found to mine is a Mid 2012 13 inch Macbook Pro, but with Intel core i7 instead of my i5, and this model on average scored about 2900. My hard drive in the past has failed which about 8 months ago required a wipe and reinstall of OS X. So, do I have anything to worry about? And what are some alternative methods to check the health of my Mac

How do I monitor the Line-In Sound?

I'm connecting my stereo receiver to the line-in sound jack. I know it works because I can record (and monitor) the sounds through Audacity. But,is there a way to listen to what's coming in without opening any app?
I think it's the same question as here: http://discussions.apple.com/thread.jspa?messageID=676560&#676560
and that didn't get an answer...
Thanks

You need some kind of application. The simplest is LineIn

How can we monitor the audio after the cleanup process before we actually record the trans

I have the Sound Blaster Audigy 2 ZS board and I am using it to transfer vinyl records to make CDs. Before my upgrading of Creative Media Source 2 to Creative Media Source 5, I was able to monitor the audio after the cleanup prior to the transfering process. Now I can only monitor the sound at the line input point and not after the cleanup process. Is there any way that we can do that?Vinylrecord

Assuming you mean Actions when you say "Batches", use this menu...
1. Click on the name of the actions set you wish to save.
2. Click the fly-out menu icon at the upper-right corner.
3. Save Actions, put them someplace on your hard drive other than in the Photoshop installation area.
