Error in getting statistics using DSGetLinkInfo

[Aruna Gutti]

I am trying to find the link statistics from a particular link in a Job. I am using a parallel routine to get the link statistics but getting the following error :

Update_Audit: Failed to load the library "V0S128_RXDWW06L_RouTest_Update_Audit.so"; either the directory containing the library file
is not on the library search path, or the library was compiled on a system
that is incompatible with this system: Could not load "V0S128_RXDWW06L_RouTest_Update_Audit": /opt/IBM/InformationServer/Server/Projects/LCDW/RT_BP245.O/V0S128_RXDWW06L_RouTest_Update_Audit.so: undefined symbol: DSGetLinkInfo.

I compiled the routine in the same system on which DataStage is running with the same compiler options. I also tried this on another Linux server with DataStage Version 7.5.2 but getting the same error as above.

Could someone please help me resolve this. We already opened a ticket with our service provider couple of weeks back.

The following is the c++ Code in the Routine :

Seems like DSGetLinkInfo routine is not identified. Are the datastage libraries in the library path variable in your environment i.e. LD path or SHLIB variables. Also, check if dsapi.h has function DSGetLinkInfo declared if not I think you have to include the .h file in your code that has the function declaration.

Just some thoughts...
