Port-channel "bouncing" but physical ports are not

Refer to the attached PDF for topology diagram and configuration information.
Here's the issue. According to the logs on DC2-5548-P1 and DC2-5548-P2, port-channels Po3107 and Po3108 are going down numerous times. However, in the same timeframe, the physical interfaces are not reporting any down/up events at all. This issue began just a few days ago. Before that, the systems were operating fine.
NOTE: Po29 is the vPC peer link between P1 and P2.
UPDATE: I totally missed this in the logs somehow but the 5Ks are showing that the physical ports are bouncing. "show interface" output shows the "interface reset" counter incrementing on the physical ports. This problem started in two separate environments 9 minutes apart at approx 01:52 AM on the 16th of March. I'm wondering if there was a power event of some sort which caused physical damage to the hosts. Seems kind of odd that 3 servers started having similar issues within 9 minutes of each other in two 5K environments.

Hi,
Putting the EtherChannel to the "on" mode will force the ports to become bundled unconditionally but the true problem, then, is truly seeing if it works. The Cisco switch will happily keep the ports bundled and will even transmit data over these ports but how do we know if Oracle is happy with that and does the same?
Personally, I would not recommend using the "on" mode precisely because of lack of any indication that things are operating just as they should, unless it can be shown without doubts that Oracle runs without LACP and uses a static EtherChannel.
Best regards,
Peter

LACP port-channel down but Individual ports up

I have setup an active LACP consisting of two members in each port-channel. As it is configured now the individual ports are operational but not participating as members of the LACP. Not finding any reference to exactly why this is. From what I can gather this may be related to the host configuration?
If anyone can enlighten me to such a situation it would be greatly appreciated. Would be even better if anyone had experience with the Oracle Database Appliance requirements for network configuration on the Cisco side.

Can I create a port channel to two switches that are not stacked?

Two switches, not stacked, but connected together via 802.1q trunk.
Server with four NICs, capable of trunking and LACP.
Can the switches be setup to have an etherchannel between the two switches and the server?

Hi,
In short NO
You would need to connect your server to only ONE switch if you want all 4 nics in the same TEAM.
You could use 2 TEAMS and put 2 nics in each forming a 2 port etherchannel to each switch

Hi,
I purchased Huawei Dongle and trying to connect with my new MacBook Pro (OS- Mountain Lion) USB port 3.0 but unfortunately it does not support.
When I plugged in my macbook the power is flowing in dongle due green light blinking twice in every 3 sec but no connection found or diver shown.
Please let me know how I have to use it. I got some suggestion for USB hub 2.0 but It does not make any sense and driver installation.
So please suggest proper direction to use it and provide link to install any driver.
Thanks
Tauheed Ahmad

Yes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and 3.0 knowledge. They handsUp that reason I posted my problem in this forum.
So is there any better solution to use any mediator between these USB version handling, Please let me know.
Thanks

If you are now in the US then you can only use the US store, so you should update the address on your account
Changing country : Change the country of your iTunes Store, App Store, iBooks Store, and Mac App Store account.
Had you copied the songs over to your computer's iTunes library, do they show in the Music section on it ? You can copy purchases that you still have on your iPad over to your computer's iTunes library via the File > Devices > Transfer Purchases menu option

Try a hard reset of the Nano. To do this, press and hold both the Select (Center) and Menu buttons together long enough for the Apple logo to appear.
I assume you have double checked to make sure you are plugging the headset all the way in meaning the white part of the headset is flush with the body of the Nano?

What is the problem specifiaclly?
If the images are intended for web use I would recommend converting them to sRGB which could be done with Edit > Convert to Profile or with File > Save for Web, but as including a Save step in Actions and applying them as Batch can sometimes cause problems I would go with regular converting.
You could also try Image Processor Pro.

You need to transfer the iTunes library, not just the music.
Copy the entire /Music/iTunes/ folder from old computer to new computer.
Launch iTunes.
This is all you need to do

I recently had to wipe my hard drive thanks to a download happy teen. In that process I lost my LR4 catalogs I was able to redownload the program but the catalogs are not there and not all of those pictures are on my external hard drive because same said

In that process I lost my LR4 catalogs I was able to redownload the program but the catalogs are not there and not all of those pictures are on my external hard drive because same said teen decided they were going to borrow my external hard drive without telling me and "made room" on it. Is there a way to recover my catalogs? Please tell me there is because I was in the middle of working on a session when I had to wipe my drive and I would REALLY like to not have to go back and reshoot it. Any help would be wonderful!

It depends on how you wiped your drive. Depending on how you did it, only the directory was erased and the data can be found with drive recovery software. Some are free, although there is a small charge for most of them (~$30). You can usually download a trial version that shows if it will work and you have to pay to be able to save the found files. Use Google to search for the software. Different programs work differently and can find different things.
Good luck.

HT4075 I tried the steps mentioned above but the changes are not being saved.

I am not able to edit or merge PDF files. I followed the steps mentioned in the Mac support community but the changes are not being saved. Any solution to this?

The link you posted gives be a 404 not found message.
The reason you're getting the repeat is because your site name is wilgenroos.nl and the first page of your site is wilgenroos.
The standard URL for domain names that are forwarded with the CNAME method is:
http://www.domain_name.com/site_name/page_name.html.
You can change the site and page names in iWeb to give you something more informative about the site and page.
If you're publishing to a 3rd party server and want to get rid of the site name in the url and only have
http://www.domian_name.com/page_name.html
do the following:
publish the site to a folder on your hard drive (already done)
use Cyberduck to upload just the contents of your site folder to the root folder of your account on the server.
You should delete the old site folder and files that are currently there beforehand.

Reporting Services 2012 - "Database is up to date, but some sites are not completely upgraded"

Running SharePoint 2010 SP1 (Feb-Mar 2012 CU)
Is there any official word from Microsoft regarding the issue with SQL Server Reporting Services 2012 for SharePoint where 2 of the reporting service application databases show "Database is up to date, but some sites are not completely upgraded".
ReportingServiceDB - Database is up to date, but some sites are not completely upgraded
ReportingServiceDB_Alerting - Database is up to date, but some sites are not completely upgraded
I'm building the new Reporting Services into a new DEV environment and I'd like to know what the official word is from Microsoft. Is Reporting Services 2012 ready for production?
Thanks!

Hi mikea730,
Thanks for your psot.
Based on my research, I found a similar thread about this issue at Microsoft Contect site. For more information, please see:
http://connect.microsoft.com/SQLServer/feedback/details/721067/database-is-up-to-date-but-some-sites-are-not-completely-upgraded
It might be a known issue of SQL Server 2012. I would suggest opening a case with Microsoft Customer Support Services (CSS) (http://support.microsoft.com), so that a dedicated Support Professional can assist you
in a more efficient manner.

Created a trigger but new values are not inserting in the backup table

I have created a backup table and writter a trigger on a table such that after update old values and new values are to be inserted into the backup table, but new values are not inserting. I am giving the code please help me
create or replace trigger "SUPPQUOTES_AUDIT"
after update or delete on phsuppquotes for each row
begin
insert into phquotes_audit(cprc_new,suppcode,itemcode,cprc_old,negodt,validdt,userid,TRANDATE) values
(:new.cprc,:old.suppcode,:old.itemcode,:old.cprc,:old.negodt,:old.validdt,:old.userid,SYSDATE);
end;

old values and new
values are to be inserted into the backup table, butwell you have only one insert there, inserting old values with a new id (which is ok if you don't update the id column, but I don't think that :new is available for deleting ops); you should have two inserts:
insert into
phquotes_audit(cprc_new,suppcode,itemcode,cprc_old,negodt,validdt,userid,TRANDATE) values (:old.cprc,:old.suppcode,:old.itemcode,:old.cprc,:old.negodt,:old.validdt,:old.userid,SYSDATE);
if (updating) then
insert into phquotes_audit(cprc_new,suppcode,itemcode,cprc_old,negodt,validdt,userid,TRANDATE) values (:new.cprc,:new.suppcode,:new.itemcode,:new.cprc,:new.negodt,:new.validdt,:new.userid,SYSDATE);
end if;
