Hello everyone!

Some time ago, I changed the configuration in SQL Runtime Statistic to "Turn on Stats code generation to gather stats at the Open and Close of a query". With this change, the CACHE base (cache/mgr/cache/) has grown a lot to reach 198GB.

Yesterday, I returned the configuration of SQL Runtime Statistic to the default which is "Turn off Stats code generation" and the cache base is no longer growing.

My question is?

We are seeing more and more customers being lured with latest infrastructure technologies, particularly Composable Infrastructure. Coming with all sorts of data center consolidations and costs savings.

Question is: are there any concerns for HealthShare/TrakCare being run on these platforms or things to look out for? Anyone out there, already on these platforms?


To be more specific this is HPe Synergy with 480 Compute blades booting as bare metal.

During some consulting activity, I found at the client's site CACHEAUDIT database of more than 100 GB size. The reason was simple: several processes produced a great amount of %System/%System/OSCommand audit records due to frequent external calls ($zf(-100,...)). As it is well-known, those events can be easily disabled systemwide, while this can be hardly considered secure enough. Reducing the number of days before audit cleanup from default 62 to some reasonable figure (e.g. 15) seems to be a better solution, but...

Hi, we suddenly noticed that one of the edge storage increased by 30% and it was due to ERROR globals which was throwing repeated error for 7 days and it consumed 35GB space. Is there a way to log the storage of edge production on daily basis and compare the increase in storage with previous day and if increase is 5% more than trigger an email to system admit to look why the storage increased suddenly.

Timeout for $zf

In one of the projects, when we have ECP with 10 ECP application servers, from time to time we faced the issue when our journals fail to purge, due to open transactions. While we have about 100-150 GB journal files per day, it quite quickly became a big issue, and with mirroring a very big issue. Mostly we just rebooted our ECP Data server, so it searches rollbacks any transactions, but such process is too long, may steal a few hours. I did not find any way, how to get the list of the open transactions from one place from ECP Data Server. We just migrated our Data server to 2018.1.

Hi Team,
             If any possible to  add a rewards list of Intersystem cache certification to Intersystem Global Masters. For example ,developer or global master user have 10000 point as , we give any offer(price) to attend the Intersystem cache/Ensemble/IRIS certificate. So no.of developer try to attend the exam and get certification.This is very useful for developer career and we also have lot of Cache developers in the market. Please correct me, if I am wrong..

Thanks ,
Ponnumani Gurusamy.

We are currently implementing the Data Innovations Instrument Manager product.  In setting up our backup process we are wanting to use Veam snapshots. The application runs in a Caché 2016.1/Windows Server 2016 instance.  We are running an HA primary/secondary/arbiter config. The statement below is from DI.  I am curious to see what others that have implemented the DI Instrument Manager in the same or similar config have in place for backup.

"DI recommends is recommending that we not perform snapshots, but if you do choose to do so, here is some important information to consider.

Hi, I have used CSP to exec SQL selects from  any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:




CSP Webpage:

TEXTBOX: Introduce your select:

Just wondering if anyone knows if there is a way to get daily emails or alerts about changes to a cache database.  I know that all of that information is contained within the journal files, just wondering if there is a way to bundle it up each day and send it off for auditing, etc.

Any solution where a plain-text/readable format of changes to the cache database could be sent or stored for review would solve the issue.

I've setup ODBC connection so I can access Cache data within SQL Server.

I want to be able to write SQL queries for internal monitoring purposes, similar to what's possible with SQL Server.  Specifically I want to be able to check mirroring status (i.e. check which is the current primary mirror member), check the status of any Ensemble productions (started/stopped), check the status of business hosts etc.  I want to do all of this from SQL Server to go with our other system monitoring solutions.

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:


(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()


License Server summary view of active key.


     Distributed license use:

Current License Units Used =        1

Maximum License Units Used =        1

License Units   Authorized =      200


     Local license use:

Current Connections =      1  Maximum Connections =      1

journal restore failed with ZJRNFILT

The steps are as follows:


1. create global

 For I=1:1:200 Set ^ABC(I)=""
 For I=1:1:200 Set ^XYZ(I)=""
 For I=1:1:100 Kill ^ABC(I)

2. create ZJRNFILT

ZJRNFILT(jid,dir,glo,type,restmode,addr,time)    /*Filter*/
  Set restmode=1                                  /*Return 1 for restore*/
  If glo["^ABC",type="K" Set restmode=0           /*except if a kill on ^ABC*/


3. restore

Hi -

I'm trying to follow the documentation, but I seem to end up in a circular reference, where the docs say "Login to TrakCare" to get access to the Layout Editor, with a link to "Logging Into TrakCare", and then that whole sections assumes that the account being used has been created, but doesn't seem to point to any means of actually creating the account in the first place.

Where is it described in the HealthShare Documentation, how to create a TrakCare login account?

I have a business process.

if it has an error it dies, or if a have a catch all/fault handler the execution flow goes there.

However, I want another behavior.

If any error occurs I want the process to "Pause" (and alert me), so I can figure out what went wrong and resume from the last request.

Here's an example of how it could work:

  1. If an error is caught, call BO
  2. BO defers response
  3. BO sends alert
  4. Fix BP
  5. Manually resolve deferred response

I'm not set on the exact  pause/resume mechanic but I hope it makes the general idea of what I want clear enough. Ideas?
