I have oracle 11.2.0 installed on linux. And I have arcgis server 10.2 on the same machine. I created an geodatabase. But when i try the sde functions like sde.st_asText i got:

-ORA-28575: unable to open RPC connection to external procedure agent



I googled it and figured it out that there is some changes to be made in the listener.ora and tnsnames.ora files. So i did.

here is the changes that i made in the listener.ora file:


(ORACLE_HOME= /mypath/dbhome_1)(PROGRAM =extproc)(ENV="EXTPROC_DLLS=/mypath/libst_shapelib.so"))

After restarting the listener. I tried the same query above. But the error remained same. So i checked the listeners status with lsnrctl - status:

Service "PLSExtProc" has 1 instance(s) Instance "PLSExtProc", status UNKNOWN, has 1 handler(s) for this service..

I searched for reason for UNKNOWN status part. And i figured out that the listener should not be added by manual intervention on listener.ora file. It should be added dynamically with srvctl addlistener command.

Here is the command that i am going to run:

srvctl add listener -o /mypath/dbhome_1 -1 "TCP:1522/IPC:extproc"

Before trying this, i have couple of questions:

Shall i remove both the changes that i made. or just first one. Because as i understand, the command shall create the first part. Do i have to write another command or just left it as it is.


(ORACLE_HOME= /mypath/dbhome_1)(PROGRAM =extproc)(ENV="EXTPROC_DLLS=/mypath/libst_shapelib.so"))

In oracle documantation for 11.2.0 it says; for the external libraries configuration in the extproc.ora file is enough. But i tried it it does not work and give the same error why is that.

Thank you.
