#Caché

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

Documentation.

I have a Powershell script to backup up a Cache database. The script runs through and backs up the database with the normal 4 iterations. The script successfully produces the backup file and an associated log file. However, after completion of the backup there is what appears to be a permission error. I have not been able to find any information that would help me determine if this message impacts the integrity of the back up. From the end of the output of the backup:

I setup an account in Cache and when I try to sort the dictionary item in the file by using the command SORT DICT filename, where filename is the name of the file i.e. SORT DICT TEST, I get the following error CMQL: The DICT entry "FIELD.ASSOC_" is not defined

The LISTDICT works correctly. Any thoughts on how to correct this error?

We will be transitioning from a server running HP OpenVMS to one running RHEL 7. The main question some of the team had was what would be the best method for moving the globals to the new system.

Also, I was wondering if any others have transitioned from OpenVMS to RHEL. If so, were there any kinks that we should be aware of prior to transition?

Node.js version

Does anyone know where to find a cache.node that works with Cache version 2016.1.1.108.0? I am currently getting this:

Error: Unable to load shared library C:\InterSystems\TryCache\bin\cache.node''

I am using Windows 7 Pro + SP1.

Thanks!

I'm trying to write a method to Export SQL Privileges from an instance by namespace, user, or roles. I've found two classes that might work:

  • ##class(Security.Users).Export
  • ##class(Security.SQLPrivileges).Export

One (Security.Users) exports an XML file and the other (Security.SQLPrivileges) exports an SQL file.

SQL or Cache Function?

Hi -

I'm creating a custom report in Health Insight via SQL and one of the requirements says that I must include patients who are >= 13 years old (which is easy) but I also need to include patients who WILL be 13 years old as of December 31st of current year that the report is ran in.

I see that there is an Age column and an AgeInMonths column in HSAA.Patient. and of course a DOB column. I'm wondering if it is possible to do this purely using SQL (and SQL functions) or if I will have to incorporate a COS function to achieve this requirement.

Any suggestions?

Hi Everyone,

I am trying to reference a field, however, in our production environment, it can be found in the first second or third iteration. My code was only qualifying on the first iteration. I have been attempting to include all iterations, but I have come up short...below is a snippet of what I am attempting to use. My original code simply had GetValueAt("PID:13.4") but this only referenced the first iteration. Thanks for any thoughts!

using sql link table wizard

I'm trying to create an sal connections from one cache system to another. I've created the connection part and I think that is working. When trying to link a table through the link table wizard, I'm getting an error "<MAXSTRING>zCreateOneLinkTable+52^%CSP.UI.SQL.LinkWizardResultPage1.

Is this due to my global block size in the new system not being large enough? It is currently set at 8192.

Thank you

Mike

I have a 2GB CSP.log file that I need to investigate.

I'm using a %Stream.FileCharacter() object to open the file and then using the .FindAt() to search for a particular string.

I'm seeing the FindAt() stop after processing 49m characters?

Here is my code:

k
s stream=##class(%Stream.FileCharacter).%New()
d stream.LinkToFile("d:\csp.log")
s x=""
s i=0
s j=0
w stream.Rewind()
w stream.AtEnd
w stream.SizeGet()
while(stream.AtEnd=0){set i=stream.FindAt(-1,"Invalid password",x)+i  set j=j+1}
w stream.AtEnd
w i
w j

Which gives the following output:

Sounds odd - but I encountered it - twice now. Cache was restarted. in that period the primary journal directory was full and it was writing to the secondary journal directory. So upon start-up, it was quite obvious that it was not going to write to the primary. Cache reported this but was able to continue with the start-up but writing to the secondary. All of a sudden it doesn't recognize the 'primary' config any more and started saying 'Alternate and primary journal directories are the same'.

Hi,

The following sql statement is working through the SMP but couldn't make it work through the code.

The table is a linked table to oracle db.

Tried to change the date property in the linked table class from %Date to %String and also tried using %SQL.Statement and %Library.ResultSet

this work through SMP:

INSERT INTO PACKAGE.SOME_TABLE_NAME

(EFFECTIVE_START_DATE,MORE,DATA,HERE)

VALUES (to_date ('2018-04-01','yyyy-mm-dd'),123,456,789)

In the code i'm using '?' in the statement for the parameters.

Hi all,

Do you know if there is a way to create a Lock that is related to an existing transaction, in the sense that if transaction is finished (commit or rollback) Lock is removed. I ask this because in the following example Lock is there until process is killed.

Example :

TSTART

Lock +^MyLock

TROLLBACK

I know, that, Caché itself is locking internally a table register when doing an OpenId with exclusive flag during the transaction life. For example :

TSTART

I have a very large logistics software running Chache.

I need to build an external application ( Web & Mobile) . I was thinking of using Angular. Does anyone have experience with this infrastructure ? What would be the best way to extract the data ?

Cache Studio 2017.2

Hi all,

I hope this is the right forum to ask this type of question, but I'm running out of ideas.

For reasons beyond my control, we run a version of Intersystems Caché (2013.1) that is not supported by Atelier. As such, I use Caché Studio to do my development.
The issue I have is, I don't run Windows or MAC, but Linux (Ubuntu 18.04 in my case). I've successfully managed to get Studio working using Wine and pretty much everything is usable.

I have a CACHE.DAT file that is working under CACHE version 2015.1.0.429.0

I have a second machine with CACHE version 2017.2.0.741.0

When I attempt to add/use the CACHE.DAT in the new version of CACHE, it will not mount.

How do I upgrade/convert the DAT file to make it work under the new CACHE version?

Thx. Larry...

Is Cache the preferred database source for extracting data elements for use in Health Share Patient Index or is there a significant benefit in sourcing data from a warehouse, data mart, or MV? I realize that could be a loaded question with 100 other questions that may follow, however, if there is a known advantage to extracting data from a particular data storage type, the answer may highlight that point.
