I am using SQL Server 2008. I am confused about which account will be used when a SQL Server agent job runs. My confusions are,
SQL Server agent as a Windows Service which we could control from Windows Service Management Console, from there we could set the account to run SQL Server Agent (LocalSystem in my computer);
Could I set SQL Server agent job level account to run on?
Could I set in each step which account SQL Server agent job step will run on?
I have above confusions because 3 different account systems may be used and my concern is what is the actual account each step will run on, and I want to avoid any permisson issues (i.e. I want to make sure the account have enough permission.). Any comments or advice? Appreciate anyone could clarify the 3 levels of accounts, which makes me very confused.
thanks in advance,
George
I would typically run the SQL Server Agent jobs under the same account as your app accesses the database.
If that account is too limited in its permissions (which might be a good thing!), I would create a single account for that app and all its SQL jobs (if that's possible) and run all SQL jobs under that account.
You could potentially run each step under a different account, but I wouldn't use that in general (it just makes it really hard to know and understand what is run under which account). Only use it if you have to run a particularly sensitive step that needs a bunch of extra permissions and those permissions are only available to a particular system account or something.
The account under which the SQL Server Agent windows service runs really doesn't have an impact on what your job steps will be run under.
So it boils down to really just two accounts:
one account is needed to run the SQL Server Agent Windows service - this is a Windows account on your machine / server which needs to have enough permissions to run the service, start and stop it - either use LocalSystem, Network Service, or whatever other Windows account you have to run services with
The other account would be the account to run your SQL Server Agent steps under - that's typically a SQL Server account (which could be based on a Windows account), and it needs enough privileges inside SQL Server to do its job, e.g. it needs access to the database objects and all. I would strive to have just one account for each app that runs the SQL Server jobs - makes life a whole lot easier!

PS: To set the user to run a step under, you need to use the "Advanced" page on the Job step property dialog and select the user from a popup window:
You can create Credentials in SQL Server (use Mgt Studio, under Security). Then create a Proxy in SQL Agent to use those credentials, telling it what kind of job steps can be used by the proxy. Then you get the choice to use that Proxy in the job step itself.
So... I make accounts for various SSIS packages to run under, so that I can keep the SQL Agent Service Account low privilege, and use a proxied credential with slightly higher privilege (not admin though, just enough permission to connect to other systems, including the File System).

I have a question regarding the purpose of some service in sql. What does the process, the purpose of them.
OracleSchedulerXE
OracleORADB19Home1MTSRecoveryService
OracleOraDB19home1TNSListner
OracleRemExecServiceV2
OracleServiceXE
OracleVSSWriter
I tried to find something about OracleSchedurXE but I did nt find anithing.
Thank you.
If I Google any of the service names, I get back several pages that go into detail about what they do.
OracleSchedulerXE is used by Oracle for the dbms_scheduler package that lets you schedule jobs to run inside the database.
OracleORADB19Home1MTSRecoveryService is used for interacting with the Microsoft Transaction Server. Most commonly, that is used to allow applications to manage distributed transactions that involve Oracle and other Windows services.
OracleOraDB19home1TNSListner is used for the TNS listener.
That's the process that allows users to connect to the database from remote machines.
OracleRemExecServiceV2 is a service used by the Oracle Universal Installer during installation that will be removed once you reboot after a successful install.
OracleServiceXE is the service that actually runs the Oracle database
OracleVSSWriter is a service that interacts with the Windows Volume Shadow Copy service to ensure that backups see files in a consistent state.
I've setup a Service Broker on one of databases to automatically pick up stored procedures in a specific schema (Build) and run them on a daily basis. So far everything has been running fine, however we've now got a need where we need to access a remote sql server which is running SQL Server 2017 and has the latest Machine Learning Service installed.
I've given the service account that runs the primary SQL Server (SQL 2016) access on the remote server, and ensured the Service Broker is executing under the service account, rather than the local SQL account (sa).
Whenever we try to access the remote server, we are getting the following error:
Linked servers cannot be used under impersonation without a mapping
for the impersonated login.
I've tried adding an EXECUTE AS to the process, however this doesn't seem to make a difference. I've also ensured it is running under the service account, and it is.
I can get it to work using a mapped login on the linked server, however this isn't ideal, as we don't want to run the sql server in mixed authentication as this has been determined as an IT risk.
I've run out of ideas or what I can do here, and can't find any other help pieces with this same problem. I did want to roll this process out to more of our warehouse builds, however this is a deal breaker at this stage.
help?
Ok, I am running SQL Server 2008 R2 on a small environment. I currently have the data on the same drive as the backups (I know, bad idea, but I just inherited this challenge). I have several jobs setup to notify me if they fail.
My boss is good with SQL and knows how to maintain the system, but is not a dedicated DBA, which is why they hired me. Well I was just going thru their setup for the AM jobs and they had several fail last night. Wondering why this did not generate any emails, I decided to do a little digging.
One thing I found was that the SQL Server Agent service was running under a domain login that really isn't used anymore except for SQL. I changed the agent to start under the "local system account" and restarted the service and the emails started coming in. The problem is, that the agent needs to run under the domain credentials due to some of the jobs that run.
How can I set the user account to have the privileges as the local system, to be able to run the emails? As soon as I set the agent back to the domain login, then the emails stopped working.
I can't comment until my reputation is higher so forgive me if this "answer" is off the mark. But the first thing I would check is whether the domain account has permissions to the MSDB database.

I am working on DW with SSAS cube. While development, my Cube is hosted on SQL SERVer 2008R2 on a development Server (Windows Server 2003).
Now, post to development phase I need to host the cube on test Server which would be on a remote location to which I do not have the access.
What are the possible ways I can host it on the server keeping in mind that If needed I need to re-deploy on server from BIDS Studio (when some bug arises).
What credentials I'll be needing (Will it do If I have a SQL sys rights or a windows account in that domain is a must)?
Thanks in advance!!1
In theory you shouldn't worry about it, taking into consideration of course, you have someone with access to the destination server.
You should never use BIDS to deploy your cube, it cant deal with partitions or security for example. Every deployment would overwrites these management settings of the target server.
Instead, you should use the Deployment Wizard to create your script and the you would send it to the person responsible for the deployment.
If you need more info about the deployment wizar, check my answer on this post
Best practices recommend not installing Sql Server to run as SYSTEM. What is the bare minumum you need to give the user account you create for it?
By default, SQL Server 2005 installation will create a security group called SQLServer2005MSSQLUser$ComputerName$MSSQLSERVER with the correct rights. You just need to create a domain user or local user and make it a member of that group.
More details are available in the SQL Server Books Online: Reviewing Windows NT Rights and Privileges Granted for SQL Server Service Accounts
Typically I create a Domain User with only the specific rights on the network which I will require the server to have (i.e. to write to the network backup drive), I then add the account to local power users or local administrators depending on what needs to be done on the machine, however this isn't required. I've installed SQL a number of times using a standard user as a Service Account but you need to ensure that the user has access to write to the resources as listed at https://web.archive.org/web/20081223155956/http://support.microsoft.com/kb/283811 . Its probably not as defined an answer as you wanted but I'm only a developer (not a professional DBA / System Engineer).
