SSIS Error – the path for isserverexec.exe cannot be found

Recently been working with getting multiple SQL Instances on one machine to work. When I uninstalled an old one it affected the latest one. Then all of a sudden my ETL jobs failed. It did not make sense at all seeing as I removed a different instance.

Got the following error when trying to run my ETL jobs or when trying to deploy the jobs:
“the path for isserverexec.exe cannot be found”

Looking for solutions online, they recommend going into the registry. Which didn’t work for me.

I ended up using the install file and running it to add features to an existing connection. And there is was Integration services was not installed for the instance that I was getting the error with.

Installed SSIS on the current instance that needed it and all worked perfectly after that and the jobs ran as perusal.

Hope this helps someone else in the future.

MDS Backup Strategies

Recently a colleague and I had a discussion about which method is the best to use for backing up MDS (Master Data Services) for disaster recovery. We came to the conclusion it all depended on the SQL environment version you were recovering to. Below are the 2 different methods for backing up an MDS database.

Model Backup

  • Fast to create, can backup specific versions
  • Will always be able to deploy a model to a MDS install
  • Can be automated via SSIS
  • Can be restore to a server version that is +1, 0 and -1


  • If you want to save backups of different models, then the models will have to be backed up separately.
  • Security is not retained; it will have to be redone. Can take about 2 minutes per user. On a small model this should not be a problem, however, when scaled out it could be very time consuming.
  • Saving more than one backup of a model would require a script/maintenance task to remove backups older than X amount of time.

When deploying the model, the option DeployClone must be used, not DeployNew. DeployNew will remove the MUID and therefore will not allow any changes to be deployed to that model at a later stage. DeployClone keeps it all intact and will allow for future updates.

Database Backup

  • Security is retained
  • Simple to set-up and maintain
  • Easy to restore
  • Maintenance tasks to clean up old backups


  • Cannot be restored to a server version less than the current version.

The database backup for MDS can be scheduled just like other backups. You can use the maintenance wizard to set up the backup and clean up task on a schedule.

If you know what version the disaster recovery environment will be on, for example the same version as the current MDS server version or higher, then it is simpler to use the Database Backup method. If you are uncertain of what version the disaster recovery version will be then you would want to use the Model Backup method in case you have to restore to a version less than the current MDS server version.

Hope this helps you to choose what is best suited for your environment!

Special thanks to Janlo Du Toit for the discussion on these methods 🙂

Creating a “Run As” Account for Scheduled ETL Jobs

When working in large SQL production environments that have multiple jobs doing different things you might want the ETL jobs to run as another account other than SQL Server Agent.

This can help with security by limiting the amount of access the account has to the databases the packages in the ETLs are connecting to.

This is quite simple to set up. I recommend using a Windows AD account. In my example below of the setup I shall be demonstrating how to create an account to run the ETL jobs.

Step 1:
You will need to add the account to the Logins under Security on the server where the jobs and are executing and the ETL projects are deployed to.
Step 1

Step 2:
You will need to create a Credential under Security that links to the account you created. Right click on Credential and select New Credential…
Step 2

Step 3:
You will give the Credential a name and select the ellipse just below it so that you can select the Windows account you added under Logins in step 1 and click Ok. You will then type in the same password for the Windows AD account and click Ok. Now your credential is set up.
Step 3
Step 3a

Step 4:
Next you will need to add the Credential to the SSIS Package Execution Proxy so that it can execute SSIS packages on the server. Expand the SQL Server Agent node, expand the Proxies node and right click on SSIS Package Execution and select New Proxy…
Step 4

Step 5:
Give your Proxy a name. I choose to use the same name as the Windows AD account throughout the entire setup. Then select the ellipse next to Credential so that you can add the Credential you created in step 3 and click Ok.
Step 5

You will notice that SQL Server Integration Services Package is checked under Active to the following subsystems. This allows the account to execute SSIS packages. You can click Ok and the setup is complete.
Step 5a

You will now see the Proxy you created under SSIS Package Execution.
Step 5b

Step 6:
When you create the new job and in the steps section set the type to SQL Server Integration Services Package, you will then be able to click on the drop down below Run as and you shall see the Proxy account you set up. You can select it and then your job will run as that account.
Step 6

An important note to remember is that the Windows AD account you are using will need Read/Write access on the databases that are used as connections in the ETL packages.


Scripting Multiple SQL Server Agent Jobs

Thought I would share this useful tip on how to script multiple SQL Server Agent jobs into one script in order to execute it on another server.

For example, you have ETLs and backups scheduled on a DEV server and you want to replicate the jobs onto the PROD server. If you have one or two jobs it would be easy to manually create them. When you have a quite a few more jobs that need to be replicated it can be quite tedious to manually create each one on the other server.

There is a simple trick for you to script out multiple jobs from SSMS and run them on another server.

Step 1:
Connect to the server where the jobs are located that you want to replicate. Expand the SQL Server Agent node in Object Explorer and click on the Jobs node and push F7 on your keyboard.

Alternatively, you can access the Object Explorer Details by clicking on View on the top Menu bar and selecting the second option Object Explorer Details

This will open up Object Explorer Details

Step 2:
Next you will select all the jobs that you would like to replicate. You can do this by holding Ctrl in on your keyboard and clicking on each job. Then right-click on one of the highlighted jobs and select Script job as -> Create To -> New Query Editor Window


Step 3:
This will script out all the jobs into one window. You will then need to do a find and replace to change the server name to the name of the server you will be executing this on.

You can do this by highlighting the server name. In this case BIDEV and pressing Ctrl + H on your keyboard which will open up the Find and Replace dialogue box. Next you will enter the name of the server you want to run the script on and click Replace All.

A pop up will appear to tell you how many occurrences were replaced.

Step 4:
The last step will be to copy and paste the script onto the server you would like to replicate the jobs on. Alternatively, you can save the script and copy the script over to the server you would like to run it on and open it up in SSMS, then click execute once open.
