LKM getinfo returned string not visible in IKM

Question

ODI 11.1.1.6.2
We are staging a number of tables using DB links and I have created an Oracle to Oracle LKM that has a single step to capture the source table name and DB Link so that it can be referenced by the IKM;
   <% v_src_table=odiRef.getSrcTablesList(0, "", "[SCHEMA].[TABLE_NAME]", ", ", "") + "@" + odiRef.getInfo("SRC_DSERV_NAME"); %>
The IKM has a single step with an Oracle Insert that references the variable that was defined in the LKM;
   from <%=v_src_table%>
The returned string is complete when referenced in a subsequent step within the LKM, however, only the schema name, table name and the '@' are returned to the IKM query. The DB link name is not. I have tried a number of different technologies and variables but I cannot pass the DB link name to the IKM.
Does anyone know of a way to pass the string returned from getinfo  in an LKM to an IKM?

Answer 1

I was able to force the LKM to evaluate SRC_DSERV_NAME by adding a step for substring. This solution does not require getFrom and is used for loading single tables across a DB Link. Views are not required.
LKM
   <%
     String v_src_table=odiRef.getSrcTablesList(0, "", "[SCHEMA].[TABLE_NAME]", ", ", "") ;
   %>
   <?
      v_src_dserv= odiRef.getInfo("SRC_DSERV_NAME");
      v_src_dserv = v_src_dserv.substring(0);
   ?>
IKM
   from    <%=v_src_table%>@<?=v_src_dserv?>_<%=odiRef.getInfo("DEST_DSERV_NAME")%>_extract
Our DB Link naming convention is <src_dserv_name>_<dest_dserv_name>_EXTRACT, making the solution context aware.
