SYSTEM IDLE PROCESS SHOWING TOO MUCH CPU USAGE

I Have problem with system idle process showing too much cpu usage.but the process is normal.nothing more else.my laptop is toshiba satelite pro m300.pls give the solution as earliest as possible.

Without knowing the excat model or what software, hardware or external components are running CPU usage is just an average measurement. If you have alot of background components/software running can cause a high reading, as it you allowed updating to runn consistently, or IM Messenger to consistently gain access.

Hi
In our XI landscape, we have XI development server and XI production server. We would like to create the
XI Quality instance for testing. Also we want to refresh XI devepolment server from XI production server.
Here XI 3.00 is installed on Unix platform with Oracle 10g database (SAP WebAS 6.40).
Pls let me know the following:
1. Can i create the XI quality server with System copy option from XI production server? or do i have
to create XI quality server with the new installation? What would be the best option?
2. I 'm not able to get the system copy process of SAP Web AS 6.40 for XI. Pls forward me system copy
document or send me SAP link for the same. I have the System Copy document for system based on SAP NW 2004s SR1 ABAP+ JAVA. Can i use this document?

Exchange Server 2010 - High Availability and Disaster Recovery - English (United States)

We have 2 Exchange 2010 servers and trying to setup HA/failover using DAG setup with DNS Round Robin
Both servers have mailbox, CAS and Hub roles. We are planning to configure DAG and then setup Network Balancing through DNS Round Robin by creating multiple A records for MX record on the external DNS and internal DNS with minimum TTL. My question is what
will happen to the emails in transit if one of the servers goes down ?
I hope this makes sense
Thank you

Hi,
Based on my knowledge, the message can still be delivered.
Let's look at the process for internal mail flow here:
1. Microsoft Exchange Mail Submission service
- Notifies a Hub Transport server role in the local Active Directory site when a message is available for retrieval from a sender’s Outbox
2. Store driver
- Retrieves messages from sender’s Outbox
4. Submission queue
- Stores all messages on disk until processed
5. Categorizer
- Processes one message at a time from the Submission queue
6. Store driver or Send connecotor
- Delivers the message to user mailbox if the mailbox is withing the site or in case if it is on remote server delivers the message through a Send connector.
In your case, the server suddenly goes down after you send message, the messages will be received at last.
When it comes to DNS round robin for CAS servers, we usually consider the Outlook connectivity. If one CAS connected fails, then Outlook will try to re-establish connectivity to the other IP address.

Too High Wakeups-from-idle per second

I am using Arch for the past few months and I have been noticing that the battery is draining much quicker than it used to be in windows.
I used powertop and found out that the "Wakeups-from-idle per second" is way too high. It is ~300 per second on average and once i even saw numbers like 8000 !!
The link http://www.linuxpowertop.org/powertop.php quotes it is possible to get 3 wakeups running a full GNOME desktop. It says that 193 is lot more than 3.
But in my case the numbers are way too high than expected. I run Arch with XFCE4.
Can somebody explain why am I seeing such high numbers and is this the reason for my battery draining ?

nachiappan wrote:Can somebody explain why am I seeing such high numbers and is this the reason for my battery draining ?
Powertop shows what is causing the wakeups. If it is the kernel, trying a different frequency governor might help.
More than likely tweaking a few different settings together will get you more battery life, the wakeups alone won't be doing all the battery draining.
There's lots of helpful hints on power saving here:
https://wiki.archlinux.org/index.php/La … ttery_life
edit: seems your cpu isn't being monitored correctly. 3000% seems so wrong.
What kernel and cpu are you using?

DCOM was unable to communicate with the computer xyz using any of the configured protocols; requested by PID 7b28 (C:\Program Files\Microsoft\Exchange Server\V15\Bin\MSExchangeHMWorker.exe).

Hi,
Previously I've two exchange server 2013 named : ABC and XYZ. After is decomm XYZ, i got this error :
DCOM was unable to communicate with the computer XYZ using any of the configured protocols; requested by PID 7b28 (C:\Program Files\Microsoft\Exchange Server\V15\Bin\MSExchangeHMWorker.exe).
EventID:10028
Source:DistributedCOM
May I know the reason why the server keep looking for the non-exist server and how to terminate this process?
Thanks in advance.

Hello,
It seems that error message occurs on the same machine with the previous Exchange Server you have decommissioned. Have you reinstall the Windows System after uninstall the Exchange
Server?
You need to check the registry keys but this is not efficient solution. The most efficient way is to reinstall the Windows if it is convenient.

Free Busy takes over 30 seconds to retrieve on Outlook 2010 using Exchange Server 2010

We have a small 100 user domain running Exchange server 2010 and outlook 2010 clients. The issue is that Retrieving Free/Busy takes over 30 seconds.
So someone is trying to schedule a meeting has to wait Minutes see the Free/busy time for many users.. I have checked and all the users in question have published at least one month free busy time.
It seems it would be much faster. Anyone have this same experience and know of a way to speed it up?
thanks in Advance
David

Hi David,
Does the issue happen in OWA? In Exchange 2010, the free/busy information is retreved by using Availability service (EWS url). Generally, if a user wants to view free/busy information when create a meeting, the http Availability service request
would send to CAS server.
Please check whether the usage in Exchange server is high when the slow free/busy information occurs. This reflect time would also be related to the network in your environment.

CUCM 7.1.2 and Exchange Server 2010

Hi,
I have a cucm 7.1.2 installed and configured and an exchange server 2010 box as mail server on another system.
If I want to send voice mail from Cisco IP phone through the cucm to the exchange server, do I need an external voice mail like Cisco Unity, or the cucm should have everything I need.
Thank you!

Hi -
If you want to use Exchange 2010 as your voicemail system, you need an Exchange server hosting the Unified Messaging server role. Microsoft has specific requirements for using Exchange unified messaging as well as licensing for your voicemail subscribers. Here is a good review - http://technet.microsoft.com/en-us/library/bb125141.aspx. Plus there should be an integration document for voicemail functionality, I found the CUCM version 7 integration doc here - http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d5db0297-7850-4f52-b965-b8006b4c05f5&displaylang=en

Exchange Server Dynamic quorum for two AD site

Hello All,
I have some query regarding the Dynamic Quorum issue:
The environment is two Exchange 2013 in first AD site and another Exchange server 2013 on second AD site. So, total 3 node exchange server.
1. Can i configure DAG with dynamic quorum on this scenario?
2. If first site is totally down then second site can work without any interruption.
3. Is there any need manual switchover in this scenario?
4. OWA and outlook can work if first site down?
5. If first site down then second site exchange server db can automatically mounted.
Thanks,
Parvez

Hi,
1. Can i configure DAG with dynamic quorum on this scenario?
By default dynamic quorum will be enabled once the node is added to the DAG
2. If first site is totally down then second site can work without any interruption.
1.sequential failure on dag nodes - first node in dag will go down and after a short time second node will go down .
2.simultaneous failure on dag nodes - majority of the nodes will go down at a time .On your case majority is two.
Dynamic quorum will support sequential failure of nodes and it will not support the simultaneous failure .
So on your case if you perform manual sequential failure on the dag nodes you can make utilize the dynamic quorum feature .
Note : Please refer the below mentioned blog which will give you a good clarity.Like you they have also demonstrated with three nodes.
Reference
blog : http://www.msexchange.org/articles-tutorials/exchange-server-2013/high-availability-recovery/exchange-2013-dag-dynamic-quorum-part2.html
3. Is there any need manual switchover in this scenario?
Yes it is available .You can follow the below mentioned article .Though it is for exchange 2010 but it will support 2013 .
http://smtpport25.wordpress.com/2010/12/10/exchange-2010-dag-local-and-site-drfailover-and-fail-back/
4. OWA and outlook can work if first site down?
You need to point the outlook and owa namespaces to the exchange 2013
server in DR site or else it would be to an LB in DR site.
5. If first site down then second site exchange server db can automatically mounted.
At a time , If the entire site goes down then the automatic failover will not happen ,because
the dynamic quorum doesn't have the enough time to recalculate the dynamic weight.
Please feel free to reply me if you have any queries.
Thanks & Regards S.Nithyanandham

Exchange Server 2013 failover design

Hello:
I'm designing a failover Exchange Server 2013 solution. I only need mail and calendar services.
I'm planning to put two physical servers with Windows Server 2012 R2 with (or without) Hyper-V to run one virtual machine in
each physical server.
I don’t have external storage device, I like to use database replication
Also, I have a physical third party anti-spam firewall
The questions:
I need one VM for Mailboxes and a separate one for CAS (4 VMs in total) or I can install 2 VMs with MBX+CAS in each VM server?
I need a third server to avoid brain duplication, or isn’t needed?
Exchange Server 2013 supports POP3 connections?
Thanks for your time, and sorry for my bad English!
Un saludo! Juan Segura

The questions:
I need one VM for Mailboxes and a separate one for CAS (4 VMs in total) or I can install 2 VMs with MBX+CAS in each VM server? - Definitely you can go for multi-role servers
to combine MBX+CAS and in fact that's
recommended except couple scenarios.
I need a third server to avoid brain duplication, or isn’t needed? You need a witness server but that can be non-Exchange server too. You need to add Exchange trusted subsystem
in Local Admin group of that server
Exchange Server 2013 supports POP3 connections? - Yes, you can have POP3 connections

Exchange Server 2013 architecture

Hi
We are planning to migrate Exchange server 2010 to 2013 with DR.
Could anybody please tell me the recommended design for this..
I am planning to put two CAS Server, two mbx server in production site and one CAS server , one MBX server in DR site.
Enabling DAC in DR site.
This design is ok or else i need to put all roles in two server in production and one in dr..
Please advise...

Either option would leave you with at least one available server per role in the main site, except that with two servers, you would have two servers holding the role not affected by the failure of a given server.
For example, you have CAS1, CAS2, MBX1, MBX2.
If MBX1 fails, you still have two CAS.
If CAS1 fails you still have two MBX.
What's generally more of a problem is quorum for the DAG cluster.
If you loose the main site, the database mailboxes cannot mount in the DR because they would not "have quorum".
This is adressed at the bottom of this article:
http://technet.microsoft.com/en-us/library/dd979799(v=exchg.150).aspx
This also addresses the notion of "quorum":
http://www.msexchange.org/articles-tutorials/exchange-server-2013/high-availability-recovery/exchange-2013-dag-dynamic-quorum-part1.html
You might address this (at a greater cost) with two DAG nodes in each site and with a FSW and alternate FSW.
Just a note: if you want all-around high availability, you would want to consider the CAS role as well (perhaps you have) which usually involves use of some form of load-balancing (or DNS round robin in a worse case scenario - not optimal).
Load-balancing between distant sites can be more of a challenge. If you have more questions, ask away.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

Problem with Integerating Microsoft Exchange server as Webdav Repository

Hi all
We are using MS Outlook 2000.
I created an HTTP system with the exchange server domain name and the corresponding user id and password required for authentication.
Then i created the Repository Manager using WebDav Repository template.But when I go to component monitoring it gives error in the server as server not connected.
How to rectify the error?

hi,
Have you set the protocol to SMTP.
You have to create a system alias for the exchange server. have you done with it?

Steps to restore a failed exchange server 2003

If I have a recently taken full backup of my failed server what are the steps to restore it.
I mean, After installing OS, then may I have to create the domain or restoring full backup creates domain automatically?

Hi,
Firstly, I’d like to explain, if you want install the Exchange server on the server you have installed OS, I recommend you just add the server into domain and create the domain on another server. Because it’s not recommended to install Exchange sever on
DC:

How to recover mailbox details in Exchange server 2007

Hi,
Problem is Exchange server 2007 user mailbox has been deleted and it’s already purged. Now we need to recover that mailbox. Is there any way to recover purged mailbox in Exchange server 2007?
Or we are planning create new mailbox and help me to find old mailbox server and database details then I will restore data from backup. Please suggest if you have better idea than this one. Thanks

I would suggest using one of your backups and creating a recovery database and pulling the users mailbox from that recovery database.
