Operating Systems





Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Hello, I'm trying to up an Oracle Database for a customer, and i have a few issues with it.

When i'm on a DOS and type "lsnrctl status <service_name>
i got an answer "Instance <name>, status BLOCKED, comport 1 handler(s) for this service..."
Command Success. (Could be not 100% accurate as I trad myself from french)

In a other hand, when i'm trying to connect with SQLPlus on the DB,  i got the following :
"ORA-01033: ORACLE initialization or shutdown in progress"

All services linked to Oracle are running exept OracleRemExecServiceV2.

As my lsnrctl start, stop and status gives answers, I dont know if problem comes from my listener.ora/tnsnames.ora (that was the previous problem I got and think have pass through).

Also SQLDeveloper send back the ORA-01033 error too.

The oracle DB version is 12c
OS is Windows Server 2016 64 bits

Blocked Message afterr lsnrctl status

ORA 01033 at login attempt
I've tried to shutdown then startup DB, reload services.
The only thing I got is tnsping answer well.

If you need anything more for precision feel free to ask.

Thank by advance if you have an answer, I digged in many sites but no one give a clear answer that applied well for me.

I have been asked to evaluate/review approximately 150 servers on our network, ranging from Server 2008 to Server 2019 list in  a spreadsheet with very limited information.   Just primary roles. (e.g. DC, DNS, RODC, SCCM Distribution Point, File and Print server, etc.)   It also lists Hyper-V, Hyper-V on workstation, etc.  

I don't have the owner information so I can't reach out to each and ask "what is this and what's it for?  The objective is to go through this giant list and label each with a "priority #" to either decommission it, upgrade the existing OS, determining the utilization of each server, apps installed, roles installed, etc.   I then need to be able to share my findings with the rest of my team so we can then determine the effort necessary to migrate, upgrade or decommission the server(s) as we look forward to our newest 2016 functional level infrastructure.  Fro example, there are 14 RODCs at branch sites, but Sites and Services is not configured properly, so that could be a priority #1 (through 5) for us.   How do you experts approach these types of tasks and projects?   What do you break things down to and label it as to what should happen to each server and where it should reside, e..g Azure.

Thanks for any information you can provide.
I want to transfer the operating system of a laptop to another laptop. The OS is Windows 10. I want to transfer it to a laptop which has Windows 8 for its OS. How do I do this?
I have window os image in esx host that will be exported to another server In the same network

My question is will it impacted to our primary web server because after export we will have two servers ip and everything the same

If it has conflict, how it should be fixed?
I have a spare Lenovo thinkcentre that I have been working on for several weeks with an issue involving Bitlocker encryption and TPM.  Have tried too many things to mention and now am to a point where the tech I am working with has advised that I need to "change the default boot mode to UEFI (currently set on Auto or Legacy) and redeploy the OS (Windows 10).  Supposedly TPM 2.0 should work with the UEFI boot on a GPT partition.  When I change the boot mode to UEFI in the BIOS and restart I get an error 1962 - no operating system found.  Any guidance you can provide on how to deploy the OS with the default boot mode set to UEFI would be appreciated.  Thank you
I think I am ready to roll on my final proper game coding.

I can get html/javascript code running from my local OS X XAMPP  7.2 local server, of course, w MacBook IP address..but is isn't always-up, and I need it always on.

But, for an intended final product, I've been looking at the options for a real-world type dev system.

It looks like Amazon Web Services has very reasonable options for eventual monthly billing. here

I'll use the free tier.
For now, I need only the ability to put a simple page up that can load a device .io game in html and serve the game code to the player browser / device correctly.
Is that what gameLift is suited for? If I put my working .io game directory in my Godaddy space, it doesn't work. I apologize for bringing up Godaddy again. It'll be the last time, I hope. So, gamelift can serve an .htm that pulls up its .io code?
Is gamelift mainly for MMO games / games w player accounts?
I'd say that - My first game - .io game - is most similar to games like word-scapes and Drag-'n-Merge, not yet fortnite or Slither.io

I am attempting to reload a Dell 5400 laptop with with Windows 10 Enterprise OS using a USB stick.  Usually I can find a way to set this boot option in the BIOS but for some reason I can't seem to figure it out on this laptop.  

I read a few articles suggesting that this feature is no longer available in the BIOS.  Is there any way around this?  What are my other options to load a new OS on this laptop if I can't boot to USB?

BIOS version is 1.4.2

Thank you!

AD OS version . Domain functionnal Level? etc
Hello Experts,

We have an urgent requirement to install a solaris t4-2 sparc server which is very old. It has 2 x 500 gb and 4 x 2 tb drives. We want to use 500 gb drives independently one to install Solaris OS and other for running some test app, the 2tb drives will be on raid1e for storing db files.

Now we are unable to boot to default os that ships with this t4-2 as it is old we are not sure if it will, so planning to install custom os solaris 11.2 and  we are planning to use as a test setup to create 3 ldom one for web app, one for db server and other as test

what is the best way to get this up and running?

Thank you in advance

I need to upgrade 2 of my PCs to Win10 and just want to check in with you Experts before I start, to make sure I do it correctly. Both are custom builds and all of the hardware on both systems are compatible with Win10. Also, for both systems, I have 1 SSD dedicated to the OS and programs only, while storing data files on several internal HDDs.

My questions are:
Do I just wipe the SSD clean, install Win10 and then reinstall software, or is there a way to only uninstall Win7,  install Win10 and keep the current software installed?

For one of the systems, I'm also upgrading the SSD from 250gb to 500gb so I'm assuming that for that one, I'll just replace the old SSD with the new larger one, install Win10 and install my software.

Thanks and I look forward to hearing from you!
I am trying to track down what should be an obvious question, but one which seems to be ignored on the 'Net:

When you enable an application-consistent backup in VMware, it configures the VMware Tools component inside the guest operating system to take a VSS Snapshot, which then engages all of the active VSS Writers to ensure that all data write activity has been quiesced prior to the backup.  This is all the easy part.

Now for the hard part: What happens if the system administrator never sets up shadowcopy storage within the OS?  Or, more directly, do you need to configure the operating system's VSS storage (i.e. vssadmin list shadowstorage) in order for this to work?  I have seen references that VMware handles the snapshot duties, which would seem to imply that you do NOT need shadow storage configured.  However, I can also see where the VSS environment within the guest OS would depend on it, and it might refuse to allow a VSS snapshot to occur without storage being available.  Which is it???
Just got a second residential computer who has MS Bitlocker locked drive due to scammer and ransom.  This person was searching the internet and got the usual call this Microsoft phone # for support.  The person was from India, and started to tell him the usual and once he had bitlocker setup, he switched to demanding $2,800 to save his computer.  This computer has no valuable information on it, and will be just wiped and clean OS installed.  But I have been given time to see if I can unlock the system for future knowledge against this type of scammer.  Any information is greatly appreciated.
The laptop is Sony Vaio SVF1521B4E.
I have repaired it by changing the original defective motherboard (i5-3337U) with a cheaper version (Pentium 987).
The laptop boots and works normally from an extern USB with Win 8.1 live OS.
The laptop is stuck when I boot from original SSD with Win8.1.
No matter what repairing method I have tried, it says cannot repair Win 8.1.
I do no want to install Win 8.1 from scratch, because I need some programs/settings from existing Win 8.1 installation.
I do not have a previous saved session to returns/recover from that point.
I would prefer a kind of install repair, but everything what I have tried it does not work, it says always is a failure and cannot repair Windows.
Maybe it has to something to do with some settings/drivers related with previous motherboard or the boot (GPT) partition or I do not know, but I would like to avoid clean re-install of the Windows.
What suggestions do you have?
I have a Dell Precision workstation that needed a new RAID controller. The closest match available to the one in the system would not recognize the foreign drives and array from the old controller. I created a new 9TB array, downloaded the OS (Windows 7 Ultimate) to a flash drive. That's how Dell shipped the system. I can boot the OS with an MBR-formatted USB stick that sees UEFI. I have the driver for the RAID controller, and the computer sees the controller and the drives after the driver's loaded. However, it won't see a partition larger than 2TB, and won't format/install WIndows on any partition/space on this array.
Questions: Using Rufus or some other such tool, how do I put the OS on a stick that'll allow it to see and USE one large partition (or maybe two smaller ones, but use the entire 9 TB)? THANKS! :)

We have an iMac, 24 inches, from 2007. There is a Mac OS Lion installed on this computer. We want to install a newer version of the operating system and we tried 'Sierra' already but we didn't succeed. Regarding that, we would like to ask you which latest version can we install on this iMac?
I have Window Server Dell R 510.
The OS is Windows 2019 server.

Goal:  I need the server would be “cleaner” to make it a little bit faster (If possible, by using the built-in tools from the Windows OS)(Note: The RAM in the server is already 32 GB). Any suggestion?.

How to change the location for Documents, Desktop etc to a different drive

I added a second "Data" partition on my PC.  Now I'd like to change the location of Documents, Desktop, etc to that new partition.  I know how to right-click on Documents, choose, Location, and edit the setting.  But in the past I've had issues where I set it to D:\ and then couldn't change it to anything else later.

Is there a procedure for "Best Practices" in this regard?  e.g. create a Docs folder - d:\Docs and then use that for the location of the library file "Documents"?

My goal is to have all my data on the D: drive, so that if necessary later on I can re-install the OS without affecting most of my data.

Windows 10

Thank you
  I have a relatively old server that I am  trying to use as Hyper-V replica server.
  It has Intel® Server Board S5500BC,  Xeon E5645 2.4GHZ 12M (6 core) CPU, 32GB RAM, LSI Logic SAS9260-8I SGL.
  I am going to set up Hyper-V OS on two SSD drives on RAID 1  and looking for enterprise grade SATA 7200rpm Hard Drives by either Seagate or WD. Preferred capacity is 8, 12, 14 or 16TB on RAID 1.
 What make/model hard drive have best track record? What make/model would you recommend?

I have a server HPE ProLiant ML350 G6 with a power issue. For the best I know, disks are fine (2 x SAS drive, RAID1). OS is Windows Server 2008 R2.
I would like to access data, just to extract some backup
In your opinion, is it possible to extract one of these disks, and insert into another server (I have an old PowerEdge 2950)?
Thank you
I'm using Rapid7 and would like to run a scan against my network of all machines.
