SID given in connect descriptor could not be established when connecting through the second listener

I have a BI 10g database with 2 instances using listener port 1522.I configured a second listener using port 1521 the first listener uses port 1522. When i try to connect to the database I开发者_高级运维 get the SID given in connect descriptor could not be resolved

I have configured my listner.ora to point to the database using port 1521 as well my tnsnames and when i to a lsnrctl serives I dont see both SIDs i only see PLSEctProc

when do a lsnrctl status I can only see the second listener with port 1521

is it possible to have 2 listeners listening to the same instances in the same server?

Two listeners on a different port to the same database shouldn't be a problem. Have you set the TNS_ADMIN parameter ? (pointing to another tnsnames.ora / listener.ora file)
