InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.

We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:

I'm running a query, joining nine tables together. When I run it with a SELECT COUNT(*) I get about 200,000 rows. When I run the SELECT with the columns I want, I get about 2,700 rows. Is there something inherent with the queries that limits the result set size, or anything I can do to make sure I'm getting back all the results? Rather, than trying to run it about 100 times limiting all previously gotten accounts.

Hello,

Very much keen if we could gather the per namespace and business component utilization of InterSystems cache server.

For e. I have a PRD server where its CPU utilization is at max all the time and I want to know which namespace and its business process (service/Operation/Process) is utilizing what number of CPU and memory.

** I can get the CPU and Memory utilization per Cache.exe and PID, but not able to get the Namespace and ConfiguratioName to which that particular PID belongs.

Thank you,

Hi Community,

I have a problem I am hoping someone can help with - I have created a front-end with HTML/CSS/JS in a CSP page in Iris Studio. I am trying to use objectscript on the back end to connect to a SQL Server Database (with valid credentials), and execute a stored procedure.

I have a fileList variable that is a stored as a comma separated string through a user input textBoxContainer. This is to be used as a parameter in the stored procedure called @Docs

Hello,

One of our clients has a 'Notes' class with over 3 million records. We have a report that pulls data from this table that was taking about an hour to run. Our test environment (which has a copy of the production database) runs the same report query in 1 second.

We attempted to purge and rebuild indices which made an improvement (down to 15 minutes) but still not great.

Concatenation Issue

I am trying to add a value to my concatenation string and the value is not being inserted in the right place. I am adding onto this code from another developer and cannot seem to get it to work. The only code I have added is underlined in bold red.

This is how the translated HL7 message looks:

OBX|1|CE|CDX^History||Specimen 1 Clinical History: CLINICAL HISTORY\.br\\.br\Specimen 2 Clinical History: CLINICAL HISTORY 2\.br\Specimen 1 Suspected Clinical Diagnosis\.br\Specimen 3 Clinical History: HISTORY 3\.br\Specimen 2 Suspected Clinical Diagnosis

I have a few routines in ^rINDEX that are missing in ^ROUTINE. At least some of those routines lack a timestamp, probably Date and Time Modified in ^rINDEX. It causes D %RO crash when such a routine is referenced by a routine range, since "" is an illegal $ZDTH value.

Healthy entry (note the timestamp): ^rINDEX("ABC,"INT") = $lb("2021-06-15 15:08:38.846885",) ;The second argument is sometimes present and sometimes not, likely the routine size.

Unhealthy entry (note an empty timestamp): ^rINDEX("DEF,"INT") = $lb("",21)

Hello everyone

I have a question about the maximum number of active license users for CACHÉ.

When I run the command: Do $System.License.ShowCounts()

I get the following return:

3 Maximum active users
0 CSP users currently active
1 Maximum active CSP users
0 CSP sessions currently in 'grace period'
1 Maximum CSP sessions in 'grace period'

I'm using a %Net.HttpRequest which had been successful in the past, but started failing at some point with a SSL/TLS protocol error.

Hi

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

Good morning, everyone

I purchased an HP LaserJet M101-M106 printer, and I'm trying to print via the Windows cache device, but I can't get it to work.
I can send it, but it doesn't print.
Physical device name: |PRN|HP LaserJet M101-M106
Type: Other
Subtype: P-DEC
Open Parameters: “W”

Could someone help me with what might be happening?

Otherwise, thanks

I have an old .NET 4.5 project, working with database InterSystems.Cache. The project is deployed on a Windows server. Data is retrieved using the InterSystems.Data.CacheClient.dll library.

But now I'm planning migration of the project to .NET 8 to container with linux centos.

How can I get data from InterSystems.Cache in this case?

As I understand it, InterSystems.Data.CacheClient.dll is only for the .NET framework.

Dear Fellow Cache Gurus: I would like to know if there is either any built-in Cache Date/Time function or an easy way to include a timezone abbreviation such as EST, PST, MST, etc... within the Cache Date/Time formats.

I read through the Cache Documentation but could not find anything to achieve this.

So if I do the following command: $ZDateTime($H,1,4,,,4,,,,,"InvalidDate"), then I get an output like this: 02/27/2025 11:10AM

But I am looking for the output to be formatted like this: 02/27/2025 11:10AM EST

Using Cache 2017.2 sever as my target.

I have a x64 Ubuntu client setup going. This is NOT server. Just client.

I have the Linux Ubuntu x64 ODBC driver gzip file.

ODBC-2018.1.5.659.0-lnxubuntux64.tar.gz is all I could find. Someone posted it in another post.

I can connect to a test sever that does NOT use SSL. That works pretty easily.

But I have A server with SSL enabled. With Windows Cache ODBC drivers I can use SSL just fine.

This is what my SSLDefs.ini file on the Windows machines look like and it works just fine.

As I was trying to create a routine search query via RoutineList, I discovered that documentation both for Cache and Iris offers only ABC* and ABC? syntax for including routine names and, unlike %RO, does not offer name ranges. Is that indeed so?

After some system files reading, I discovered that you can EXCLUDE certain routines with ', by using the 'ABC or 'ABC* syntax. That is not documented but it should be. Any other non-documented RoutineList syntax capabilities?

Example:
