Configuring Root Bridge Primary and Secondary on a Switch Stack

Hi, Consider a small LAN using a collapsed core design with two Catalyst 3650 switches in a stack as the core/distribution layer. There are several 2960X switches with cross-stack EtherChannels to the 3650's. After enabling Rapid-PVST, best practice would be to configure the root bridge. The question is, would it be sufficient to configure the stack to be the Root Primary and not configure a secondary, based on a failure of the stack master switch would elect the slave to become the stack master and effectively become the root bridge?
Thanks
Tony

BTW, don't know if issue also applies to 3650 stacks, but on 3750 stacks, if stack master fails, I believe your port channels will reset because, by default, stack's MAC changes. However (again at least for 3750s), the stack can be configured to retain the original master MAC.

Magic Mouse Primary and Secondary Clicks Switched

Recently I picked up a Magic Mouse and have since found some very strange things that I don't know how to fix:
The primary and secondary clicks are switched. As in, under mouse settings when I select the secondary click to be on the right, only the primary click works on the right side and everything else is a secondary click. It is also very annoying because every time I have more than one finger touching the surface it counts as a secondary click. If anyone knows how to fix this I would really appreciate feedback.
I looked around in settings and couldn't find anything regarding this matter. I fiddled with some stuff but never got it working properly.
Feedback much appreciated!
--Justin

Looking at another thread in this forum, I see some people who had older apple mice installed before the magic mouse are having this problem with the magic mouse.
I had an older wireless mouse that would take right-clicks before I set up the magic mouse. Unfortunately when I connect the older wireless mouse I can no longer access it's preferences. It only gives me the preferences a generic one button mouse. Somewhere there must be some set of files I can delete and it will forget this old mouse.
I am pretty disheartened after a week of this. One of the benefits to a mac is that I shouldn't have to dig around removing drivers and such

Setting up a primary and secondary Database in Oracle 10G

Hi Experts
can you please tel me the steps involved in creation of primary and secondary database? This is the first time i am going to configure this setup. Please provide your helping hands.
Thanks alot in advance,
Ram

Absolutely glad to help.
Step 1: Clarify what it is you are trying to build. Are you talking about a Standby Database? Perhaps Physical or Logical Data Guard? If so what protection mode? Stand-alone or RAC? Or are you just trying to dup an existing database on another server in which case you can just use RMAN.
Step 2: Go to http://tahiti.oracle.com and read the relevant docs
Step 3: Go to http://metalink.oracle.com and look at the Knowledge Base docs
If you have any question thereafter contact us and be sure to include your version number, not a marketing label. 10g is a marketing label that refers to everything from the 10.1 Beta through 10.2.0.4.

Can't find my DNS Primary and Secondary

Dear God, I need my DNS primary and secondary. I'm trying to set my xbox 360 up with it's own ip ect. I've gone to my airport to get this information but my DNS is the same as the IPv4 router. My xbox requires a DNS primary and secondary. The only thing I can find for my DNS is a Domain Name and Server address: 10.0.1.1 Do I put this number in my xbox for the DNS with no secondary?

I think your router is not configured properly for your internet connection. Router is not giving out a valid DNS to the computers because it cannot obtain it (dns) from the modem. Is your connection Cable or DSL?

Primary and secondary Email accounts

Hello,
Is there a way to specify primary and secondary email account ? In case if the primary server is down, the secondary server would be used for sending the notification.
Thanks.

I am implementing something similar to what you have suggested. I was wondering if there is a way to achieve this by just changing configuration. Looks like it is not possible to configure it and coding it is the only way out.
Thanks for your inputs :)

Windows 8.1 screen bounces between primary and secondary monitors

I have a Lenovo T530 laptop with a docking station and a IBM monitor L200P attached to it.
Up until yesterday, this configuration was running Windows 8 Pro with no issues.
However today, after I installed the Windows 8.1 upgrade, I started having problems with the screen bouncing between the primary and secondary monitors without my intervention. The problem happens very regularly, regardless of whether I have selected the laptop as primary monitor or the IBM monitor attached to the docking station.
I verified that the problem does not happen with Windows 7 and Windows 8 installation and only starts appearing after the Windows 8.1 upgrade is applied.
Does anybody have similar problems
Thank you in advance.

O''philipp [[#answer-697652|said]]''
<blockquote>
another thing you could try is this: enter '''about:config''' into the firefox address bar (confirm the info message in case it shows up) & search for the preference named '''layout.css.devPixelsPerPx'''.
double-click it and change its value to '''1.2''' (or any other zoom factor that fits your purpose: 1.0 relates to 100%, 1.2 equals 120% and so on; -1.0 is the default value and will adhere to the system settings).
</blockquote>
Okay, I tried it, set it to 1.2 and even more stuff got blurry and fuzzy. Besides everything in the FF menu bar everything in the header on youtube and a few other pages did it too. It did make the pages fill the actual page better, but the blur is worse than this prob so I set it back to -1.0.
Any other ideas?

Need help with sorting records in primary and secondary databases

Hi,
I would like to store data into primary and secondary db in different order. For the main primary, I want it to be ordered by login_ts instead of uuid which is the key.

     int time_b = 0;
     time_a = atoi ( (char *)a->data);
     time_b = atoi ( (char *)b->data);
     return time_a - time_b ;
for the timestamp secondary, I set that compare function:
          if ((ret = (*sdb)->set_bt_compare(*sdb , compare_login_ts )) != 0){
Does anyone know how can I make it sorted according?

Hi,
The DB->set_bt_compare() is used to compare keys in Btree database. In the callback function, both the DBTs are key, but not data. Please refer to http://www.oracle.com/technology/documentation/berkeley-db/db/api_reference/C/dbset_bt_compare.html.
If you want any field in the data to be sorted, you might create a secondary index on it and define the compare function as you wish.

Is it possible to set primary and secondary display with 2 graphics cards?

I have an Early 2008 Mac Pro with two graphics cards and four monitors installed. Does anyone know how the computer (or more specifically Keynote) determines which is the primary display and which is the secondary?
Also is there any way to change the scheme?
What I am trying to do is switch the primary and secondary from the two monitors in my office to the monitor at the podium (would like it to become primary) and a vga projector (would like it to become secondary)
I bought the second graphics card so I wouldn't have to switch the cables back and forth three times a week. All the monitors work fine, it's just a matter of determining or changing primary/secondary
Thanks in advance

Thanks Malcolm
I got that far – The keynote manual says that the display with the menu bar is the primary display – that works out fine. The problem is that the manual says that the display without the menu bar is the secondary (or alternate). But there are three displays without the menu bar.
What I would like to find out is: is there a way to choose the display without the menu bar to be the alternate?
When I try various combinations, there seems to be no rhyme or reason as to which display is the alternate.
Thanks again for your response!

How to bind the Zero line between a primary and secondary Y axis?

All -
We are using combination charts with:
- primary and secondary Y axis (Sales versus Volume).
- Scale: Auto (Y) Axis
- Linear
- Fixed Label Size
In instances where one axis has a negative value and the value ranges are diverse the Zero line will be different for both. This causes some confusion when trying to read. Other that putting in manual (Y) axis with min and max, is there a way to force the chart to keep the same Zero line?
Thanks!

Obviously, true
The number of different features described once as "a basic requirement" is really amazing but a feature asked once is perhaps not one which must be added to a program like Numbers.
Other tools are available for professional numbers crunchers .
I know there are other threads asking about secondary axes, but your point is taken. I'm definitely not a number cruncher, but I am/was a pretty advanced Excel user.
_Go to "Provide Numbers Feedback" in the "Numbers" menu_, describe what you wish.
Then, cross your fingers, and wait _at least_ for iWork'09

P965 Neo-f - primary and secondary ide channel stops working after changing gpu

I just changed my graphic card from 4850 to 4870x2 and then my idd devices stopped working, and when I look in device manager the primary and secondary ide channel has a yellow exclamationmark over them. And the error msg is as follow: This device cannot find enough free resources that it can use. (Code 12)
And when I look on the tab resources the two I\O range tabs have a red cross like over them probably meaning there is something wrong. And in the column Conflicting devies list: Input/Output Range 01F0 - 01F7 not available.
Input/Output Range 03F6 - 03F6 not available.
What I have tried so far:
Updating the bios, looking for I\o range crashes and irq crashes, uinstalling and reintalling severals times. And when I change back to my old 4850 card the problems disappears straight away.
Any ideas?

Quote from: Crispin on 28-April-09, 20:15:49
Well reality says something different :D
And a reinstall fixed the problem. I find this post very amusing.
Ill bet your graphics doesnt even use its full potential on that board.
Me thinks it severly limited by the board and the cpu and imo a waste of a good graphicscard/money.
Its better to use only 2 slots of mem because of the strain you put on your memorycontroller when using 4 slots.
When running " double dualchannel" the memorycontroller can be overflooded when running too high mem.speeds, with errors and BSOD and crashes as a result.

Set Primary and Secondary Interfaces

How can I set up primary and secondary network interfaces, so that it will automatically fallback to the second interface when I don't have the primary connected? I tether my phone to T-Mobile's network, but when I don't have it connected it want it to fall back to my wired connection.

Sorry, I only bump my own posts when I've added additional information to my last post and I see that no one has added anything to it in the past few days. I guess I would be better to create a new post instead of editing the old one.
I did give it a try and I have no real results to share. I created the two profiles in the /etc/netctl directory and named them as above (including Priority=1 for the tmobile connection and Priority=2 for the wired connection, as stated in the wiki entry even though man netfcfg.profile says it's only for wireless connections), then I enabled the service. There is the word "interface" after systemctl enable netctl-ifplugd@ which makes me think I should specify an interface but I have no idea which one to specify, so I just enabled it without it and it didn't complain. There's no way to start it. Both connections are enabled but it seems to default to the wired connection for some reason, when I want it to default to the tmobile connection and then fall back to the wired connection. Both are enabled and have IP addresses but nothing changes when I connect or disconnect my mobile data connection since it's using the wired connection.
edit: I just tried to enable the service using the interface name of my mobile data connection and it didn't change anything ex. sudo systemctl enable netctl-ifplugd@enp0s26f7u3

Expose activates on both primary and secondary monitor corners

Hi all
I am using a dual monitor setup. Laptop screen as primary and a vga monitor for secondary running though a minidisplay to vga adapter. This is setup as an extended desktop. The 3 corners of the primary monitor and 2 corners of the secondary monitor can activate my expose settings.
I would think that using an a dual monitor extended desktop setting will allow you to activate expose, through 2 corners of the primary and 2 corners of the secondary assuming they are arranged as side by side screens.
Is this bug that we are waiting for a fix or is this something unique on my side?

During booting in the safe mode the notebook loads only a common drivers and it should be able to see something on the screen.
But if its not possible and you are not able to get the display back on the internal screen then I assume you need to boot form the recovery CD and to reinstall the OS :(
The new installation should overwrite all display settings and the notebook should works.

Exchange rate variances between Primary and Secondary Ledger

We have a little problem on our hands.....we are implementing dual ledgers with dynamic posting, primary in Canadian Dollar and secondary in USD.
Exchange rate variances would occur if for example, we consider material transactions at different points in time. We would have no problems in the primary. However, CAD to USD exchange rates are updated monthly and very likely, rates would change month to month. Therefore, exchange rate variances would happen frequently in the secondary ledger.
We have been asked by senior management how these variances would be handled by EBS. Just wondering if you have ideas though we are looking into the accounting events in SLA.
Thanks,
Sanjib

If the requirement was to maintain balance in USD and Canadian dollar, You can use the Reporting currency option instead of Secondary ledger.

Programmatically change primary and secondary Y-Axis range

Ok, so the idea is that I have a chart with two different data types on it. One is plotted on the primary Y-axis on the left side and the other is on the secondary Y-axis on the right side. Both share the same X-axis.
How do I change the range seperately for the primary Y-axis and secondary Y-axis? Whats currently happening is no matter which "Active Plot" or "Y-Axis Index" I select, it only changes the range for the secondary axis. Any help would be amazing!

We are going to need to see some code to help with this. and some clarification sinc a "Chart" cannot have multiple y axes
Assuming you have an XY Graph this little code demonstrates how to set the scales min and max programatically
