Could anyone please explain why Caché has a %STARTSWITH function while it supports ANSI SQL "LIKE"?

thank you very much.

Hi,

I have a large XML zen report file that I want to convert to a CSV, what is the most efficient way to do it.

XML file:

<Details>
<Col1> aa1 </Col1>
<Col2> bb1</Col2>
<Col3> cc1 </Col3>
</Details>
<Details>
<Col1> aa2 </Col1>
<Col2> bb2</Col2>
<Col3> cc3 </Col3>
</Details>

Expected Output:

Col1,Col2,col3
aa1,bb1,bb1
aa2,bb2,bb2

Thank you.

Hi,

I'm trying to find the faster way to get the data from a class, and I find it very slow compared to traditional globals. So, I hope some of you can bring some light to me :-)

I have thousands of registers in a class, and to access it quickly I'm going with $o at the index. From there, I get the values using $listget(). Something like that:

Currently, we have an application running in one namespace ("Database B") that has globals and routines mapped to another database ("Database A"). After enforcing clean up on Database A, we found that 90% of the disk is free. We would like to compact Database A and release the unused space. However, we are running OpenVMS, which seems to be the issue.

For databases consisting of only globals, we are able to use ^GBLOCKCOPY; however, we need to ensure that the routines and mappings are also copied.

Hello Community,

I recently encountered a issue with Caché and I can't figure out where the problem is coming from.

I noticed that the license limit (200) was reached whenever I was opening my Studio (so it seems). When this occurs, I restart Caché (with the Cube in the Taskbar), and the number of license used is back to 1%, but grows back after. The time taken before the number of license grows back again looks pretty random.

Here is a couple of screenshots :

Hi guys,

I'm working on a project with my client.
They have a visit table which has about 7,000,000 records. The table is used in a random search page witch holds 20+ conditions to be combined.
The table is defined as below:

There is several classes that allow to create TCP/IP connections (eg: to connect to a service).

Example : %Net.FtpSession (port 21), %Net.HttpRequest (usually port 80 or 443)

AFAIK connection will stay open unless closed explicitly or if variable that hold the instance is garbage collected.

Is there a way to get a list of all active (open) TCP/IP connections IRIS is maintaining so far ?

Is there anyway to improve the performance of the display of DeepSee dashboards?

It takes minutes to do the cell calculations of computing the axis members.

Any direction or help would be appreciated.

Thanks,
LG

If I were trying to access an index of a global variable, what time complexity would this operation have? My understanding of languages like Java/C++ is that arrays are stored as blocks of memory so that x[15] would have a lookup time complexity of O(1) because it just goes to (address of the array + 15) and retrieves the value stored there.

How does this work in Cache where the index of a variable isn't necessarily an integer value? If I were to have a variable like the following:

x("Adam") = "Red"

x("George") = "Blue"

x("Bryan") = "Green"

etc...

Hi,

I am testing some BI tools like Tableau, Power BI and Qlik with Caché using ODBC driver

Is there another way to connect them with Caché?

Suppose we need to store millions of values temporarily, that means, we don't care about them if we lose them but our application use them to get realtime information. Should I use Cachetemp or whatever other DB without journaling enabled? If answer is Cachetemp, shouldn't be a problem if we decide to scale using App Server + ECP? I'm not sure what would happen with the app logic in such architecture as I guess I couldn't map and share cachetemp...

Any idea/suggestion?

Running cache 5.0.21 64 bit on Windows server 2016 in virtual environment. Trying to understand why every single process disk read speed (simple sql data walks) caps around ~20MB/s, however 2 paralell such tasks on different data areas can reach 19MB/s each, four - 17MB/s each, that is 70MB/s total, etc. Also simple copy file to nul on that system reach ~400MB/s.

What can keep single query on idle system from reaching for example 200MB/s? Virtualization? Windows? Cache? Processors are below 1-3%

I work in a small development company that uses Caché as a database. In some support cases I have doubts about whether the client's infrastructure environment is not affecting Caché's response time. Reading a bit about comparing installations in different environments, both in production as testing and homologation environments , I understood that the TPC-E is a benchmarking method accepted in the market.

Hi all.

A long time ago I enabled Activity Monitoring to be able to save myself headaches in the future when looking at the performance of various message routes through our productions. It's served it's purpose of answering questions on how many messages we process a week etc but I had not had the chance to really dig down into the stats for specific message types or destinations to pin point issues.
