RE: Library Path Issue

Wouldn’t it be super nice if Oracle puked out some information about where it looked on the way to not finding it (and why it looked where it looked)?  

Those features in a linker were required for undergraduates circa 1977. Over four decades later you still have to be a sleuth to figure out what you did wrong. Sigh. That’s what we get for using a lab OS as if it were commercial.  

I miss DTSS. (But I don’t miss DaTaSyS, it was the first commercially available relational database, but it ran at the speed of a research project…)

I believe I figured it out. I thought I had copied the $ORACLE_HOME/hs/admin/extproc.ora from the other server, but apparently I hadn’t. That file needed to have SET EXTPROC_DLLS=ANY added to it.

Hi Scott,  

LD_LIBRARY_PATH=/oracle/data/scripts/lib:$LD_LIBRARY_PATH  

Have you checked $LD_LIBRARY_PATH in your listener env variables?

and you haven't shown ls -l /oracle/data/scripts/lib

has oracle permissions to it?

I have a c program that sends audit data to the OS syslog. I just moved the database from a Red Hat 7 server to a Red Hat 8 server. I had this same problem last year after applying the April PSU.  

The listener.ora contains:  

    (SID_DESC =
(SID_NAME = PLSExtProc)

(ORACLE_HOME = /oracle/app/product/19.0.0.0)

(PROGRAM = extproc)

# (ENVS = "EXTPROC_DLLS=ANY:/oracle/data/scripts/lib/syslog.so")

(ENVS = "EXTPROC_DLLS=ANY,LD_LIBRARY_PATH=/oracle/data/scripts/lib:$LD_LIBRARY_PATH")

The library is here:  

/oracle/data/scripts/lib

syslog.bak3 syslog.o syslog.so syslog.so.bak test.o

syslog.c syslog.o.bak syslog.so.051120 test.c test.so
