hi @Umer Nalla

we currently have 11 souces in our TREP and I use v1.1. As I told before the throuble must be in configuration of the ADS. With one of our six ADS it works fine.

Thank you

Hi @Reinhold.Blank,

Within the ESDK package contains the 300 Series example: 331_Directory_Streaming which demonstrates basic usage of the EMA Library for accessing and parsing of OMM Directory data.

Hi @nick.zincone.1,

I used this Sample for testing this pupose. I just remove service name as descriped in USAGE GUID to get a complete source directory with all services existing in our TREP.

But it doesn't work!

Hi @Reinhold.Blank,

I was able to remove the service name and received a complete source directory, i.e.

This was my output:

I assume you are doing the same. Can you confirm which version of the ESDK you are using and show your output window?

thanks.

Hi @Reinhold.Blank

Can you confirm how many services there are on your TREP? And also what version of EMA you are using?

There was a bug in an older version of ESDK - I just tried the 331 example in v.1.1 and it failed with a large source directory.

When I tried the same example in ESDK v1.2 it worked with the same large source directory.

Hi @nick.zincone.1,

I using EMA SDK 3.3.1. Below you see the result.

But I found out, where the throuble must be. We have 6 ADS. With one off them it works fine. On the other 5 the request fails. So I called our admins, that they check the configuration of this ADS.

Thank you for your assistance

Error Id -21 is RSSL_RET_BUFFER_TOO_SMALL. It looks like the allocated buffer is too small to encode the retrieved directory before sending to the application. I have tested with the ADS that provides a lot of services and found the same error in EMA 3.1.1..

However, after testing with EMA 3.2.0.L1, it works fine.

EMA 3.2.0.L1 has been restructured and it uses CMake to generate build files. Please refer to ESDK_C_Migration_Guide.pdf in the package for more information.
