#Callout

I would like to invoke some unix/windows commands from COS, any API could do that?

Also, I would like to set up some Environment Variables for this process which would execute the above external command.

Anyway to achieve that?

Thanks for your help.

Hi,

Is there any way to set environment variables in Linux from Cache?

I see a way to get an environment variable with: $system.Util.GetEnviron()

Essentially I am converting from VMS (DCL) to Linux.

In VMS we used $ZF(-1,"SETSYM") in Cache to a value and then interpreted that value in a DCL procedure.

Hello Community,

We have two live servers running DeepSee dashboards for users. One of the servers can print a widget to a pdf file, and the other can't.

I learned that 1) a Java JRE needed to be installed on the second server, and 2) it's trying to run an OS command to render a pdf file (details below).

An audit log of the event shows this:

I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR. I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..

I have a C string and I need to build a $lb from it.

This code works fine for strings shorter than 254 characters:

char *str = "some string";
int len = strlen(str);
int add = 2;
char *list = malloc(len + add + 1);
char lenChar = len + add;
sprintf(list, "%c\x01%s", lenChar, str);

Thought maybe someone can share the code for longer strings?

Hi guys,

I am trying to run a command line code using $zf(-1) in cache terminal. it is returning access denied error.

I have tried to run the code in cmd itself it is also throwing Access denied error. But if opened cmd as administrator and run the same code it is working perfectly. I am using windows system.

Hence i need to know how can i run the cmd line code as administrator using our terminal or studio. Please help me out.

Thanks,

Is there a way to get one of:

• Struct
• $lb
• Subscripted local variable
• List/array

As a return type from callout call?

And related question: is there a way to return several values (which may contain commas) from one callout call. Or rather what's the best approach when doing that?

I could launch a external process via $zf(-2).

However, this child process need to refer some shared libraries in RUNTIME,so I have to set up the proper paths to the environment variable LD_LIBRARY_PATH, is anyone know how to do this?

Thank for your help.

I use zf(-2) to spawn a external a Java application in a *nix instance.

I would like to kill this process after some conditions met.

I would like to leverage $zf("kill ... ") but this requires its the pid of this child process.

So is there a way to acquire the pid for the child process when I create it ?

If not, how is the suggested way to kill this process?

Thanks.

I have a simple callout library:

#define ZF_DLL
#include 
#include 
#undef ERROR

int GetRandom(double* random) {
   // Py_Initialize();
   // Py_Finalize();
   *random = 1.0;
   return ZF_SUCCESS;
}

int main(int argc, char **argv)
{
   printf("Random: ");
   double random=0;
   GetRandom(&random);
   printf("%lf", random);
   return 0;
}

ZFBEGIN
    ZFENTRY("GetRandom","D",GetRandom)
ZFEND

I compile this code as a shared library and it works fine with:

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

Thanks

I'm using callin to get global values.

Here's a simple function to get string value from global and return it:
