It depent open your requirements and the structure of your database that what kind of operating system is best. if online money transection are invloved then I think UNIX operating system is best but it is costly too.
in previouse some article it was noted that Oracle show trmendouse performance on linux server. oracle corporation certifiy RedHat Enterprise Linux 9 AS 3 for oracle Databases.
As well as concern to Hardware it also depend open requirements of your database. In Hardware people are mostly concern with processor and RAID levels.

InDesign Server CS5 and Hardware Configuration.

Does any one know of InDesign Server is supported on Intel Xeon processor?
We have a need to generate 100's of PDF that merges a Data and Images togther. Each outout PDF varies anywhere from 20 MB to 400 MB. Below is the server configuration we are planing to purchase..

Any one have any experience and any issues?

Hi there,
Yes we solved it. We had a background process in our app that was trying to send over a thumbnail generation script. This would peg the INDS server for up to 15 minutes of just doing nothing. You would see the script come across but nothing would return so it would hose. Ended up fixing the error in our application and INDS has been working like a dream.
When we were running this we only were on a single-instance. We've now migrated to a multi-instance and throughput seems to be a lot faster now.

What ideal Win Server and Hardware are recommended for 11g DBs

What best Win Server and Hardware are recommended for 11g DBs?
- Processor
- Memory
- Storage
- Network
- Etc...
Following is the scenario:
- The server will be for development and test DBs
- More than one databases will be installed each for each project
- Maximum 4 databases will be accessed each time
- Maximum DB size for each DB will be in couple of GBs.

Which version of 11g ? For 11gR2, see the requirements here - http://download.oracle.com/docs/cd/E11882_01/install.112/e16773/reqs.htm#i1011417
Any server that exceeds these requirement will suffice. Obviously the more the number of processors, the faster the processors, the more the RAM, the more the disk etc etc, the better.

Why did my server crash and what to do to prevent this?

hi there,
i've been following the installation guide on single host and all looked well until yesterday all of a sudden i couldn't see my mail tab when using webmail.
i tried re-logging in several times and from three computers at home but no mail tab was dispayed (calendar, address book, etc were fine). in some occasions i have been displayed an error msg saying i should reconfigure the server.
so i went on today to check the server but having a very limited knowledge of administration i couldn't figure out what to check and where so i stopped all services as advised in single host guide. notably web and messaging servers (or services?) weren't running. i restarted them and now require some help to diagnose why this all happened as i was not getting any emails until the server was restarted.
i was able to log in yesterday morning however in the afternoon server has crashed. it didn't restart or hung up but web server wasn't running anymore. the last email i received was 3.21 pm yesterday. after i restarted all services today, a few emails were displayed immediately with current date and time (10 am today), however i don't know whether these were emails received while server was 'malfuntioning' or they are some left overs from last seconds of working.
i remember myself running update service on the server yesterday and it looked okay today's morning when i found it finished updating the computer. could this be the reason? did update service stopped web server from running?
also after i restarted the machine this morning i had to re-run all services all over again. don't they just start automatically upon reboot? what if power fails and my APC UPS shuts machine down and then boots it back when power regains?
pls help me as i am new guy on the block and want to stick to Sun products but don't want to be put off by some mysterious errors and instability of such a great software package which CommSuite defintiely is.

It helps to have a high-level view of how things fit together:
http://docs.sun.com/app/docs/doc/819-4440/6n6jfgch0?a=view
In this case for the mail-tab to work you need messaging server running, specifically the mshttpd (webmail) process and the imapd (IMAP) process.
i tried re-logging in several times and from three computers at home but no mail tab was dispayed (calendar, address book, etc were fine). in some occasions i have been displayed an error msg saying i should reconfigure the server.The error message advising to reconfigure the server is misleading. If this was the first time you accessed the comms-express interface and had no mail-tab then the message is pointing out that you may have misconfigured something (which was really easy to do in earlier releases). As you had already successfully accessed the mail-tab this is more indicating that something is now broken/not-running correctly.
so i went on today to check the server but having a very limited knowledge of administration i couldn't figure out what to check and where so i stopped all services as advised in single host guide. notably web and messaging servers (or services?) weren't running. i restarted them and now require some help to diagnose why this all happened as i was not getting any emails until the server was restarted.Four things you can do at this juncture:
1. Configure coreadm to capture any future core dumps (assuming of course the processes died abnormally e.g. coding issue, memory starvation ...) http://docs.sun.com/app/docs/doc/819-5355/6n7eo3v6v?a=view
2. Enable auto-restart of processes. http://docs.sun.com/app/docs/doc/819-4428/bgadd?a=view
3. Check patching levels and update to address known issues. http://www.sun.com/bigadmin/hubs/comms/downloads/updates.jsp#cp1
4. Log a Sun Support Case to have the issue investigated (assuming you have a support contract). http://msg.wikidoc.info/index.php/Submit_sun_support_request
i was able to log in yesterday morning however in the afternoon server has crashed. You need to be very specific about what actually 'crashed'.
Saying the "server has crashed" implies that the entire system (at the hardware/OS level) crashed/rebooted.
If the 'webserver' has crashed then you would be able to access the system via SSH (so the hardware/OS is working) but when you connect to the server using a webclient to get mail, you don't get a connection.
If the 'mailserver' has crashed then you would be able to log into Comms Express or at least see the login page (webserver is working) but one or more components are not working (if you cannot login then chances are there are directory server issues, if there is no mail-tab then this is mail-server issues, no calendar tab, calendar-server issues, no address-book then potentially directory-server issues and so on).
it didn't restart or hung up but web server wasn't running anymore. the last email i received was 3.21 pm yesterday. after i restarted all services today, a few emails were displayed immediately with current date and time (10 am today), however i don't know whether these were emails received while server was 'malfuntioning' or they are some left overs from last seconds of working.If you have enabled mail logging then you can see when the emails were being accepted.

also after i restarted the machine this morning i had to re-run all services all over again. don't they just start automatically upon reboot? what if power fails and my APC UPS shuts machine down and then boots it back when power regains?You need to configure the various components to start-on-boot using /etc/init.d/* scripts. This is a standard system-administration task.
pls help me as i am new guy on the block and want to stick to Sun products but don't want to be put off by some mysterious errors and instability of such a great software package which CommSuite defintiely is.At this juncture I recommend that you investigate Solaris 10 administration training. The issues you have described aren't necessarily isolated to just CommSuite but are more standard system-admin tasks.

No permission to access the server app and Timemachine Backup failed

Problem:
Mac Mini Server late 2009 running OSX Server 10.6xx for years without any problem,
upgrading to Mavericks Server in Dec. 2013, running perfectly for 6 month.
No Hardware issues.
Last week i inadvertently deleted some (or most?) accounts (user and others), using the gui of the server app (and too much wine for myself).
After that i couldn’t login the app anymore, because it needs administrator rights (which were deleted).
This all caused problems by accessing some of the running services (e.g. Calendar, Adressbook, Wiki, Mail)
No matter - TimeMachine always did a fine backup job, i thought.
I restarted the machine using „command - r“, selected Recovery from TM-Backup and so on.
But after recovering and restarting the OS always hangs on reboot.
Ok - now i can do a clean install etc.
But has anyone any idea how to get back all the data of the services and the user accounts etc., using the corresponding parts of the Time Machine backup only? (Only local accounts, no network accounts/no open directory)

After reading one similar post, I've solve the problem.
It seems that I have to enable 'read and write' permission on
my site root folder.

Windows Server 2003 and Microsoft Assessment and Planning tool (MAP)

Preparing for the end of support for Windows Server 2003 (4/2015) and the need to migrate from Windows Server 2003, I have been directed on several sites run the Microsoft Assessment
and Planning tool (MAP) to aid in identifying any software and hardware issues. Apparently this tool has been recently updated (7/2014) and cannot be installed on a Windows Server 2003 system. As it requires .NET Framework 4.5 to run. Unfortunately,
.NET Framework 4.5 cannot be installed on a Windows Server 2003 as it only supports .NET 4.0.x versions. All older version links to the MAP tool have been updated to link directly to version 9.1. Where can I get a MAP tool version that will run
on Windows Server 2003?

Hi,
Yes, i would agree with arnavsharma
After the environment scan has been completed in Windows Server 2008r2 or another supported OS, MAP looks at computers running earlier versions of Windows.
http://technet.microsoft.com/en-us/magazine/ee677580.aspx
Meanwhile, for the MAP related issue, you'd better ask in MAP forums:

Source different O/S and hardware from destination

What are the limitations on using Streams to move data between Oracle instances, when those instances differ by O/S and hardware platform?
We're working with a vendor to replicate from an Oracle instance 10gR2 running on an IBM server running AIX, and we're hoping to perform one-way replication into another 10gR2 instance running on an HP server with a Linux Red Hat O/S (both are 64-bit).
I came across this document yesterday, which mentions that it's a bad idea, although I haven't seen the same restrictions in the documentation:
http://www.eecs.berkeley.edu/~nimar/papers/vldb05.pdf
Namely, it mentions that in the 3rd & 4th point
Operational Requirements for Downstream Capture
-The source database must be running at least Oracle Database 10g and the downstream capture database must be running the same release of Oracle as the source database or later.
-The downstream database must be running Oracle Database 10g Release 2 to configure real-time downstream capture. In this case, the source database must be running Oracle Database 10g Release 1 or later.
-The operating system on the source and downstream capture sites must be the same, but the operating system release does not need to be the same. In addition, the downstream sites can use a different directory structure from the source site.
-The hardware architecture on the source and downstream capture sites must be the same. For example, a downstream capture configuration with a source database on a 32-bit Sun system must have a downstream database that is configured on a 32-bit Sun system. Other hardware elements, such as the number of CPUs, memory size, and storage configuration, can be different between the source and downstream sites.
The reason why I'm concerned is that Oracle came to us about 8 months ago and sold us on Streams over DataGuard for a read-only direct copy of data. DataGuard was sold as being tied to having the recovery instance be as identical as possible to the source. They led use to believe that there were no such restrictions for Streams. So, we didn't add any provisions for purchasing a Replication tool. Now I'm thinking we might need to spring for ODI or something ...
Has anyone found differences in hardware and O/S to be a problem when using Streams?
Thanks

Sorry, wrong link initially.

I have no experience with downstream capture, which ships archives from one platform to another.
If you are not using downstreams, then heterognenous platform work fine over SQL*NET (dblink).
I have already operated in production Windows to Solaris multimaster Streams and would have gladly
exchanged the win box for your AIX.

SQL Server 2005 and ColdFusion 7

Hi all,
I am using SQL Server 2005 and ColdFusion 7 (standalone) on
XP 64 Bit. I was using the exact setup a couple of weeks ago, but
had to reinstall my O/S due to hardware problems so am back to the
beginning. I remember having a nightmare setting datasources up in
the past, but did manage to find a solution.
I have tried the following:
SQL has TCP/IP Enabled
SQL is set to Mixed Authentication
SQL has a login set to the same as my Windows Username and
password
My database has a user (dbo) by the same name as the login
set in SQL
When I add a datasource in the administrator I enter the
windows username and password (I have tried without either as
well), the server name as localhost and the port as the default
1433.
I always get the following error:
Connection verification failed for data source: DATABASENAME
java.sql.SQLException: [Macromedia][SQLServer JDBC
Driver]Error establishing socket. Connection refused: connect
The root cause was that: java.sql.SQLException:
[Macromedia][SQLServer JDBC Driver]Error establishing socket.
Connection refused: connect
Can someone offer any advice? This is driving me proper nuts.
TIA,
Paul

when i did it, i had to update my jdbc driver

Server Overloaded and Warning Status

I have a WebLogic cluster, includes 3 Managed Server running on 2 separate machines (Each has 16Gb Ram and 8 CPU - Sun Sparc). Each start with parameters
Starting WLS with line:
/usr/jdk/instances/jdk1.6.0/bin/java -server -Xms1024m -Xmx2048m -XX:MaxPermSize=128m
Some time ManagedServers have status "OverLoaded" and "Warning". When that happened , I stop and start server and server status return to OK.
Checking the status with "prstat" command, I saw that java process used just from 1Gb Ram to 2Gb Ram and CPU is under 3%, very little CPU used
What I have to do to make server return to OK status without restart?
And how to make server running with OK status everytime?
And How many Managed Server can I create on each machine with that hardware?
Thank you!

What I have to do to make server return to OK status without restart?Maybe stop some or all applications can be usefull.
And how to make server running with OK status everytime?You must tuning the enviroment, maybe should adjust JVM parameters passed to weblogic server, check thread pools, etc. For Sun HotSpot JVM, you can use -XX:+AggressiveHeap option for throughput applications, give it a try.
See [WebLogic Server Performance And Tuning|http://download.oracle.com/docs/cd/E13222_01/wls/docs92/perform/index.html]
And How many Managed Server can I create on each machine with that hardware?This decision depends on applications you want run, weblogic resources required, how many clients will be attended, and so on. If your weblogic server using 8GB achieves the goal, then you can setup another instance using the remaining available, and so on.
I hope this helps.

Constand InDesign Crashing in a Mixed Server Environment and Undeletable Lock File

Hello All,
I have been running into a lot of problems with InDesign recently. I have been working on a 14 MB .indd file with approximately 50 MB of linked files with it. ID will crash with other files open, so it doesn't seem to be file specific. Here are some details about our operating environment:
All files are located on a server running Mavericks with Server 3.0
I am using ID CC 2014 on Windows 7
2 other people are using OSX Mavericks and using ID CC 2014
I will typically have this file open for hours at a time, making occasional changes and updates. Every once in a while I get a windows dialog message that says "The network connection was lost for the file "\\FILEPATH HERE", or the file was modified by another process."
I have checked with my colleagues and they are nowhere near this directory and yet this error occurs.
After I click OK on this box, a crash box occurs for InDesign saying that I must close it. The error details are as follows:

These errors occur at random intervals, and sometimes when links are updated in AI or PS. Is there a connection there?
In addition to this, I can no longer reopen the file, as the crash causes the ID lock file to remain there, giving no access to the .indd file. I cannot delete this file unless the administrator of the server deletes the file.
Does anyone have any insights into these problems? Thank you in advance.

Set up a new group called "Workers" or something like that and put in the Users into that group. Now go to Server.app and assign the Group to your share ADDITIONALLY (not by changing the group you see in the Posix permissions) by hit the "+" sign. Give READ & WRITE to the group. The go to Server > Hardware > Storage and propagate the permissons to the included files & folders.
That should clear you problems by setting up and additional read & write permission by ACL, which is not overwritten, when a user saves a document to "The Box".

Capacity planning and hardware sizing

Hi,
I would like to know in detail about capacity planning and hardware sizing while deploying oracle database products. I need to know about properly planning the infrastructure and configuring and deploying the products. Moreover, when should we use RAC,how many nodes, exadata, DR etc. How to size hardwares RAM,Disk for this kind of implemetations.
I know it depends on budget and environment. Still if anyone kindly give some links/docs I will be able to have a decent start in this domain.
Regards,
Saikat

See , they all depend on your company policy and the database size that they are going to have.
1. Size : i have worked on databases sizing from 80G to 2000G , all depending on the client or the industry you are catering to.
2. hardware and Ram : Server Team should know this better , you can have a simple small server if the DB and application are small and the usage would be less. If it a full fledged system with high load then you need to get in touch with your server team and raise an oracle SR for exact specifications for that database and also plan for some future growth.
3. RAC : depends on the project if it requires such a setup.
4. DR : is for disaster management. Also all companies implement this by adopting data guard ( physical standby).
5. For having a good start , start reading the books and refer to oracle documentation. More you refer , more knowledge you will get .
Start with the basics.... make your basics strong.. and then move ahead with complex setups.

Migrate (N)AMP server to new hardware

Hi,
I have been looking for documentation on how to move an AMP configuration to
new hardware (practically same OS-install, NW65SP7).
Is there any info around 'cause I wasn't able to find any. And before I
start dumping MySQL databases and Apache virtual hosts, I thought i'd ask
here.
On the origin server, webcontent and SQL db are placed on different volumes
than SYS. I looked at MigrationWizard as well, but my replacement server is
already in the same tree (new name).
Any info, links or directions, appreciated.
Regards,
Marcel

BakxM,

I'd transfer the database and adjust Apache and PHP settings manually.

How to migrate os x server to new hardware

I am looking for the quickest easiest way to migrate OS X server to new hardware that I purchased. I currently have both DHCP and DNS services actively running. I have VPN services running when needed.

Reid,
Thanks for your response. I actually migrated everything that I needed over about an hour after I posted. For DNS I simply copied all of the zone files in /Library/Server/named and restarted the DNS service. DHCP took a little more investigation as I had to find where the configuration file was being stored. I eventually found the configuration in /etc/bootpd.plist file that contains all of the DHCP info and copied it over to the new system. Once I restarted all services everything was working fine.
I took this approach rather than a direct cloning as I wanted a clean install of everything on the target system. Also, as I mentioned before, I didn't have many services running that I needed to have running on the new configuration. The VPN services that I was running had only one test user so recreating it from scratch was a non-issue.

André

Upgrading from SBS 2008 and Exchange Server 2007 and Adding Modest Failover Protection

I haven't seen anyone describe this scenario, so maybe it can't be done, but it seems it should work. Can someone either confirm this is viable or set me straight and tell me it's not wise (and if not, why not).
I currently have SBS 2008 (2008 Server + Exchange Server 2007 + some other components). I use redirected folders so all my user data is stored primarily on the server, and then sync'd with their local harddrives for roaming use and as an additional
backup precaution. I want to upgrade to a modern version of Exchange (don't care too much about the underlying server OS, but seems like a good time to upgrade everything). I also want to improve the reliability for rapid recovery in the event of a system
failure. I have always felt nervous with SBS because it only runs on a single server.
My plan is:
Install Windows Server 2012 Standard on a new server machine
Join that new server to the existing SBS domain and sync the users, etc.
Install Exchange Server 2013 on the new 2012 Server
Migrate the existing Exchange data and account info to the new server
Demote the SBS Server and promote the new server to primary DC
Reformat the old SBS server and install Windows Server 2012 on it too, and join it to the domain as a second DC
Set up DFS Replication and keep all my user data folders between the two servers (so if one server fails, the other can take over, just not automatically like with a cluster)
Install Exchange Server 2013 on the reformatted 2012 Server box (so second instance on the domain) and set it up to sync with the first Exchange Server 2013 via DAG (so if either computer crashes, the other can take over for both Exchange Server and file
services)
Wouldn't that give me a complete slow-response failover system without the need for setting up a cluster (I know a cluster would provide instant failover protection, but I don't need that kind of speed - a manual switchover in the rare event of a server
failure is acceptable for us)? I could do this using cheap hardware for each server, because unless both servers fail at the same time, clients can point to the other server. And because it's not a formal cluster, I don't need to buy anything for a shared
SAN. This seems like such an obvious more cost-effective solution for a small network, I don't understand why this isn't a common approach, which makes me wonder if there is some reason it won't work.
Any suggestions or feedback? Are Redirected Folders still recommended for users on a Server 2012-based domain?
Thanks,
Colin
Colin

Ed, thanks again for your help. OK, so here's my updated plan (I realize I should probably check on some of these pieces on the Server group, instead of this Exchange group).
Constraints/objectives:
None of the machines are truly server grade hardware, but only 5 people on the network, so performance is generally not an issue, unless a given server is just pegged on CPU or HD due to its own internal maintenance tasks and can't respond to user requests.
Haven't seen any problems, since upgrading server from 4GB RAM to 8GB a few years ago.
Not going to buy any new hardware at this time, but do have several unused consumer-grade computers I can deploy as wimpy or moderate servers.
Main issue is to limit repair time in the event of a system failure (instant failover is not required, but want to be able to restore network functions within less than 24 hours in the event of a hardware failure) and minimize time spent on IT
maintenance.
Because of light IT maintenance (not anyone's primary job and we're too small to justify a dedicated IT person or to pay for outside help), almost every touch takes me research and time to re-learn what I haven't done in weeks, months, or years -- so also
want to keep all IT tasks as simple as possible.
We philosophically want to invest now for the next 5 years and avoid ongoing cloud fees (so zero interest in Windows Server Essentials with Exchange Online)
A little nervous about using VM's, just because I never have before, but I do respect that's probably the right way to do many of these things...
Currently I have SBS 2008 (Windows Server 2008 R2, Exchange Server 2007, WSUS 3, all with latest SP's, also includes SharePoint and other stuff, but I don't really care about most of it) on a single 8GB consumer grade system, which functions as a file
server and Exchange server. We use Redirected Folders and Offline files for all users, which works great for us and provides additional file redundancy (if server goes down, all of each user's files are also on their own machine and they can even continue
to work just fine w/o the server, losing only ability to send and receive e-mail). It has been sufficient, but I want to upgrade our version of Exchange and I am nervous that if that current one server fails, it would take me a long time to restore everything
from backup, easily many days, especially if I need to buy any replacement hardware. It is RAID1, so a single drive failure is easy to handle, but that's the only hardware redundancy for the current server.
New Plan:
Install Windows Server 2012 R2 Standard on a new modest machine (16GBR RAM, Core i7, 1TB RAID1 (may upgrade to 3 or 4 TB), 256 GB SSD boot drive, this had been my old personal computer)
Join that new server to the existing SBS domain (2008 R2/Exchange 2007), make it a DC, sync the users, etc.
Install Windows Server 2012 R2 Standard on a wimpy computer (4GB RAM Core i3 processor), leave it as a member server
Install Exchange Server 2013 on the wimpy new 2012 R2 Server (and nothing else, this will be dedicated to Exchange to make the most of such a wimpy machine)
Migrate the existing Exchange data from the old SBS Exchange 2007 server and account info to the new server
(or should I just create new accounts and copy the data from the user end through Outlook -- is that safer and cleaner than attempting any kind of server-level Exchange data migration?)
Demote the old SBS Server and promote the new 16GB server to primary DC. Now it's OK to take the old SBS server off the network.
Reformat the old SBS server and install Windows Server 2012 R2 on it too, and join it to the domain as a second DC (and possibly DCPROMO it to be the main server)
Install Exchange Server 2013 in a VM on the reformatted 2012 R2 Server box (so second instance on the domain for Exchange redundancy) and set it up to sync with the first Exchange Server 2013 via DAG OR set up another physical wimpy member server and install
it there. In any case, do NOT install Exchange directly on either DC.
Set up DFS Replication or a Failover Cluster (still need to research this, but I had planned on DFS, thinking Cluster required shared drive, but Ed corrected me on this) between the two DC's for redirected files and keep all my user data folders between
the two servers. We don't need automatic failover, like with a cluster, a manual switch would be acceptable, but if no additional cost or risk to clustering the two DC's, then the auto-failover protection that provides would be better than DFS.
I think this incorporates all of your points, Ed. Does this sound right now? What's your advice on #5 (how to best migrate user data)?
Thanks so much for all your help,
Colin

Deploy Exchange 2013 , Lync server 2013 and shrepoint server 2013

Hi dears ,
I have a deployment requirement in which I have to plan for deploy Exchange 2013 , Lync server 2013 and SharePoint server 2013 on premise for 500 user and for one organization , now I have been asked to provide the software and hardware requirement
for this deployment .
so I wonder , is there any guide or link to find the hardware and software requirements for this deployment ?

Hi,
You can refer to the link below about the hardware/system requirements for Lync Server 2013:
https://technet.microsoft.com/en-us/library/gg398438.aspx
Note: it is not supported to install Lync Server in the same computer with DC, Exchange Server and SharePoint Server.
If you want to deploy Lync Server, you’d better read the guide firstly before deploy it:
https://technet.microsoft.com/en-us/library/gg398616.aspx
For the deployment of Exchange 2013 and SharePoint 2013, you can also post case on Exchange and SharePoint forum, and there are more experts will help you:
