Hello,

We have what I feel is a pretty good Terminal Server Setup using Microsoft Remoteapp. We have about 125 - 150 users in at a time. I get constant complaints about disconnects, users receiving Sorry for the inconvenience error and thrown out. General Slowness in Phone Notes and chart navigation.. I just want to know I can tell my users and Management. I am the Infrastructure Manager at the company and Have been in I.T. for 20 years.. Been in this environment for the past 10years and have improved everything from where is was..

Our Network is 100% Cisco backboned - 2960X Switches, 1921 Routers and Fiber connected. We are running a 20MB VPLS to our Hosted Datacenter from Each location.

We have a 40MB internet Pipe. We have a sonicewall 2600 in front of it. All VPLS traffic is behind the firewall and does not route through.

We have HP Wireless Solution with MSM720 controller and MSM430 Wireless units.

We are running VMware 5.5

(5) Virtual Server running Microsoft 2012 server DataCenter edition - Each Server has 16GB Ram and 4 single core Virtual processors configured Xeon E5-4620 2.6Ghz

Cps Server is Virtualized Running Server 2008R2 with 16GB of Ram and same 4 single Core virtual processors Xeon E5-4620 2.6ghz

Our SQL Server is Physical Server with 128Gb RAM, Intel E5-2609 Processors (2) 2,5Ghz Has all 15k SAS drives. Server is running SQl 2012 Enterprise and Server 2012 Standard.

Our DTS Sever is about the Same Specs as our CPS server just 4GB of Ram.. Our Kryptiq Server is about the Same specs as out DTS Server and just more disk space.

Am I crazy, or should this be adequate enough to run CPS12 SP11??

I don't think you are crazy.

We are a much smaller practice. Our Server specs are not too far off yours and we only have 30 total users.

We upgraded to cps 12.0.11 december 14 2015. We have severe slowness issues. We cannot sign more than 2 documents without app crashes and we are experiencing data loss at crash.

We did not have any problems out of the ordinary at CPS 12.0.10.

GE has documented our problem thoroughly. We have crash logs with SQL and DB tracking in place. Ge finally copied our entire database 10 days ago. Still no word. The system is barely usable.

I posted similar information several weeks ago.

We are hopeful that engineering will help.

I know that you stated you only have 125-150 concurrent users, but have you considered splitting your interoperability off onto its own server? I know that GE doesn't start recommending this to companies until they start averaging 200 concurrent users, but it might be worth considering since the process takes all of the interoperability load that runs through JBoss and takes that off of your App server and runs it through JBoss on your Interop server. I truly believe that this has helped our organization with some of the slowness issues that we were experiencing when we first went to SP11, now granted we are actually at that level, average of 200 concurrent users, licensed for 264, but again it might be worth your consideration.

Another item, have you looked at building any new indexes on your Centricity tables? Shortly after I started working here 3 years ago, I worked with Visualutions (3rd Party Vendor) on an issue that we were experiencing with some functionality within Centricity and they determined that we needed some additional indexes. They told me that I should check for missing indexes on a regular basis and based on their impact create them, so I do this in the weeks following every upgrade, including SP installs, and then periodically after that. Of course, the stats for this is dependent on your reboot schedule, so if you reboot weekly like we do, then the best time is the day before the reboot.

With all of that being said, we still have some providers that complain of slowness, while others seem to work fine, but this has improved with the changes we have made. We have had lots of locked Chart errors since installing SP11, supposedly made better by Patch 6. We also do get the "Sorry for the inconvenience..." errors, but we have been getting these since I started here and we were on CPS9.5, and had them with CPS11, and now with CPS12. I have several tickets opened with GE on these errors (I pull the information from the ErrorLog table if my users don't send me the details) and some of these errors have already been flagged as known errors with there own SPR numbers. Some of our users can go days and days without one of these Fatal errors and getting kicked out, others may get a couple a day, and some others seem to get these errors about every other transaction. But it is never the same people that get hit hard and seems completely random.

We are just a little smaller than you - 125 would be about our max users. CPS 12.0.10 Patch 4.

Our hardware is pretty close to you but our db server is also virtualized. Both of us are well over the GE hardware recommendations. We are currently working with GE since we are getting some pretty long logical and physical disk waits, as well as disk queue depth, on all machines - terminal servers, appserver, and dbserver. Performance is at best mediocre with an average 5 sec screen response. Changing patients can take up to 10. You may want to get the GE perfmon templates and take a look.

We are working through users having disconnects at one site that almost looks like a problem with the Intel chipset in the new Lenovo (and others) laptops. Older laptops don't have the problem. This was the item that caught our attention in your post.

We also have the Centricity crashes, but we do seem to have driven down the frequency (or at least reporting) of occurrences.
