 I have spent days trolling forums and knowledge bases and you guys are my final try at getting an answer:

Does anyone have any idea how to pull the currentuserid when you are scripting inside on screen attribute forms inside of OpenText ECM Content Server?

In my content server volume I have created a custom attribute which using the sql that I wrote shown below will pull a specific list of values in the dropdown based off of the current username. When I type in/hard code a username (dhc) into the sql code the dropdown works and shows only the items from DocumentInfo_DocType that that user should see. When I try to make it look up who the current user is that is logged in the code fails. How do I change my sql code inside the opentext attribute form page to make it to look up who the current user is? I tried a bunch of things that I found on the web but nothing works ☹

picture of the  form screen is attached just in case that helps to see what screen I am on in my ECM opentext

I have a hyper-V server running 2012 R2.  20 cores and 256 gigs RAM.  On the host is a VM (server 2016) with 8 cores and 64 gigs RAM statically assigned.  That server runs an SQL 2016 application for route automation.  The VM is five days old, just built, prepped and put into production.

There seems to be a memory problem.

Every day since install, the RAM works it's way up to 97% and the server becomes non-responsive.

Task Manager, Resource Monitor and RAM Map DO NOT show any process using this RAM.

I repeat, the process using the RAM does not show in task manager, resource monitor or RAM Map.

I'm having the dickens finding out what is eating up the RAM and need someone to make some suggestions that might help me zero in on this.

I've thought about the 2012 R2 host and the 2016 VM and maybe its a hyper-visor issue, so, anyone know any issues with 2016 running in a VM on 2012 R2?

Anyone have any software they know of that might show me where the RAM is allocated that is not showing in the programs mentioned above that I'm using?  Something other than RAM Map maybe?

Anyway, that's the ghost I'm chasing.

Thank you for any feedback you might have.
we have migrated our SSIS packages from 2014 to 2016 in SSDT 2017.  I have a data flow task with odedb source connecting to a sql server DB with the below query. the package is running fine with no errors but no data is gettting populated
but if i run this in management studio its giving me 150 rows. Strange thing is if i remove the paramter conditions, its workign fine in SSIS but then IF i hardcode the dates its not populating any data again

do i need to refresh parameters or variables since we did the migration ? can anyone suggest what is causing this issue ?

Many Thanks

Cannot see one database in the linked server. I have three servers. Server A is running SQL 2014. Servers B and C are running SQL 2017. I have created a linked server on server B and C back to server A. When I review the catalogs under the linked server on servers B and C all but one of the databases is there. The ones that are there all have the same names. If I create a database on server B and C with the same name, the database will appear but there are no tables. What must I do to be able to see all the databases on server A from within SQL on servers B and C? I am logged into all servers as 'sa'. I have set RPC and RPC Out to True on both servers B and C.

I'd need to upgrade some software on a vm, the software uses backend SQL.
I can take a snapshot of the vm, but how do I backup (restore?) the SQL (2008)  in a quick & simple way?

As per the Microsoft recommendation, the feature will be deprecated in future versions and
recommended to not use this feature in new development work and modify applications that currently
use this feature as soon as possible.


Do we also need to disable it on existing critical servers where implemented as best practice?

In SQL Reporting Services (SSRS), the main report containing data from two subreports is displaying data accurately.

But, I'm curious as to why the data displayed upon generating the subreports "by themselves" is being pulled one day behind the data displayed on the main report.

Again, the data in the main report and pulled from the subreports is showing as accurate.  But, the subreports "by themselves" are one day behind.

What are some things to check, to determine why the timing in the main report is correct as compared to the subreports?


I have large table in access and I want to split it into smaller tables based on unique value in field one. Does anyone know of a query?

Thank you.
I want to know if it's a good idea to have database views be used for queries and reporting instead of the live database tables?  This database has 100's of tables, but I know that for their reporting, they will probably only need 5 or 6.  Thoughts?  Any body have any recommendations, suggestions for creating database table views?
I have a virtualized windows 2012 server running SQL 2014. I am using Veeam to back it up. I keep getting a warning message:

I've got two RDS installations, one with 2012 R2 and the other with 2016. I'm setting up a test environment so I can understand how to do a cluster of RDS Connection Brokers.

I setup two servers and installed the 2012 SQL native client (there isn't a 2016 native client).on each CB. I verified the cluster is working by taking one server down at a time and the cluster IP remains pingable..

In the setup wizard for RD Connection Broker for HA, it asks for the DNS of the RD Connection Broker cluster, so I put that in.

But there is no RD CB service for the cluster, just on each CB server, so the wizard fails.

I found this video (https://www.youtube.com/watch?v=kQufizuFTkk), but it is for 2008 R2. It appears I need to create the services for the cluster?

My DNS zone broker.mydomain.com points to the IP of the cluster.

Not sure what the next steps are so the HA wizard will complete successfully.
