#Caché

30

  

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

Documentation.

I have the object query:

s Rset=##class(%ResultSet).%New("%SYSTEM.License.UserListAll")

I can loop through that query and it generates the report information that I need.

I have a Python process where I use the intersys import to connect to the Cache instance. But I have been unable to determine the correct syntax in Python for this query. Being that 'UserListAll' is a query I attempted to user:

res = <query>.prepare("select * from %SYSTEM.License_UserListAll")

generate random password

Hello!

I need to create strong random password including letters and integers. Does Cache Object Script has methods to generate password or I have to create my own method ?

I have developed a process that pulls data elements from a cache instance using the tools provided with the "intersys.pythonbind3" import. This is a windows box. After validating the process, the next step is to install the process on a site (Windows) that does not have an installed version of cache and access the cache instance remotely. But, since intersys.pythonbind3 is part of the cache install, I am not sure what to do to allow this process to function because of the missing import.

EnsLib.HL7.Message Querying

We are trying to track down the source of Orphaned messages and noticed that we are unable to query EnsLib.HL7.Message with any kind of WHERE or ORDER BY clauses in our SQL statement.

I know EnsLib.HL7.Message is a system table, but is there a way we can add additional Indexes to the table to make the query run better/faster without affecting the system?

Hello,

Our team is looking for a way to export all of our Cache SQL tables into Microsoft SQL Server. I have only found a method to export one table at a time into an ASCII file. We have over 170 tables so this would be very tedious and time consuming. Is there a way to directly export from Cache to SQL Server. Alternatively is it possible to export the entire database in a single shot or even multiple tables to text files?

Thanks!

Myself and the other Technology Architects often have to explain to customers and vendors Caché IO requirements and the way that Caché applications will use storage systems. The following tables are useful when explaining typical Caché IO profile and requirements for a transactional database application with customers and vendors. The original tables were created by Mark Bolinsky.

In future posts I will be discussing more about storage IO so am also posting these tables now as a reference for those articles.

I am in the process of creating a python report writer that includes the information contained in "License Usage" page of the management portal. I think I have a handle on the local values contained in the report using the %SYSTEM.License class I have those defined using these methods:

Current License Units Used - -> LUConsumed

Maximum License Units Used --> LUMaxConsumed

License Units Enforced --> KeyEnforcedUnits

License Units Authorized --> KeyLicenseUnits

Hi,

I am running InterSystems iris 2021.1 from the container and I have version 2020.1.1 is installed locally. While running studio locally I am getting below error message:

"Version mismatch. Studio version 2020.1.1 unable to connect to server version 2021.1
Upgrade to a later version of the client to resolve this error"

Looking Forward

Thanks

I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.

Example:

Below would be the _sqltext

DECLARE @Id INT;

select id into @Id from something;

if @Id = 9

BEGIN

do something

END

The _sqltext would work in sql server, what would be the equivalent for cache for it work?

I get a generic error when I try it with cache

I have a python script that is pulling the cache instance key expiration date ( KeyExpirationDate() ) which comes back as an integer. With the queryscript function - $ZDATE(73284) I can derive the actual expiration date. Is there a manner or method of creating an equivalent Python script that will convert the integer return by the KeyExpirationDate() method into a date string?

I am writing a Python tool to query our cache instances for various information. I have set up the connection without issue:

import intersys.pythonbind3 as pyb

conn = pyb.connection()
conn.connect_now(.....)

db = pyb.database(conn)
qry = pyb.query(db)
obj = pyb.object(db)

I wanted to make the call:

execRes = qry.prepare_class("SYS.Database",'FreeSpace')

But fetching fails because of data mismatches ( as I understand from other posts) and my testing bears out this type of failure.

How to become a time lord - Time travel

Time travel is like visiting Paris. You can't just read the guide, you have to throw yourself into it. Eat the food, use the wrong verbs, get double the charges, and end up kissing complete strangers.

The Doctor

We are now going to travel through time, that is, we are going to see future and past dates and how to calculate them in different formats. The TARDIS doesn't wait, take the controls and hold on tight.

ECP system ID

Hi,

I'm looking through some journal entries in the hope of finding the root source of an issue.
I was wondering if and how you can map a "ECP system id" to a server.

Any hints would be welcome

Hi,

I was playing around with the python binding for caché (2018.1.4) and I ran into some problems.

When executing the class query "List" from SYS.Database the pythonbind interface throws an exception, that seems to be caused by a mismatch of the defined SQL datatypes for this query and what is actually returned (or the lack of type conversion in the pythonbind interface).

Is this a known issue ? Are there solutions/workarounds for this,
Or is this a bug ?

The details:

Is there a way, for testing purposes at least, to change a CSP session over to a different user? We have a lot of things in our system that are allowed or restricted based on the user login, so it would be useful for me to be able to occasionally run as a different user to see how things look and work for them. I've tried using the %CSP.Session.Login function, but that still shows the CSP session as being from the original user, not the one I've switched to.

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Java Connection Strategy

We are planning to build a REST API with the Java Quarkus Framework.

  • There'll be a connection pool;
  • The DataSource instance will be automatically injected from the connection pool;
  • We will use JDBI to do SQL instructions and this will give us automatic Connection and Statement management;

This Caché instance already have COS applications running and consuming connections and licenses.

After doing this, we will migrate to IRIS.
