Hello,
I have already have similar failures (with another lib, but the
resolution is similar).
su - oracle
ldd /usr/lib64/collectd/oracle.so
-> success
su - root (the account collectd runs with)
ldd /usr/lib64/collectd/oracle.so
-> some libs are missing
This may help you. Or not. Give a try...
Regards,
Yves

Hi All,
I have an issue with compiling the oracle plugin for Collectd, :
lt_dlopen ("/usr/lib64/collectd/oracle.so") failed: file not found
while the file exists.
Collectd Version: 5.5.0
Symptom:
# sudo /opt/collectd/sbin/collectd
ERROR: lt_dlopen ("/usr/lib64/collectd/oracle.so") failed: file not
found. The most common cause for this problem is missing dependencies.
Use ldd(1) to check the dependencies of the plugin / shared object.
Environment:
OS: Centos 6.8
DB: Oracle Enterprise 11.2
Oracle environment settings:
export ORACLE_HOME=/oracle/product/11.2.0/db
export LD_LIBRARY_PATH=/oracle/product/11.2.0/db/lib:/usr/lib
export TNS_ADMIN=/oracle/admin/network/etc
# extract from config.log (whole log file could be sent)
configure:23255: gcc -c -g -O2
-I/oracle/product/11.2.0/db/rdbms/public conftest.c >&5
configure:23255: gcc -E -I/oracle/product/11.2.0/db/rdbms/public
conftest.c
configure:23277: gcc -o conftest -g -O2
-I/oracle/product/11.2.0/db/rdbms/public conftest.c -ldl
-L/oracle/product/11.2.0/db/lib -lclntsh >&5
configure:39435: running /bin/sh ./configure --disable-option-checking
'--prefix=/opt/collectd' '--bindir=/usr/sbin' '--libdir=/usr/lib64'
'--sysconfdir=/etc' '--enable-oracle' '--enable-ltdl-convenience'
--cache-file=/dev/null --srcdir=.
BUILD_WITH_ORACLE_CFLAGS='-I/oracle/product/11.2.0/db/rdbms/public'
BUILD_WITH_ORACLE_LIBS='-L/oracle/product/11.2.0/db/lib -lclntsh'
However, looks like there are no missing dependencies
# ldd /usr/lib64/collectd/oracle.so
linux-vdso.so.1 => (0x00007fff18bc9000)
libclntsh.so.11.1 =>
/oracle/product/11.2.0/db/lib/libclntsh.so.11.1 (0x00007f62c8d61000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f62c8b44000)
libc.so.6 => /lib64/libc.so.6 (0x00007f62c87b0000)
libnnz11.so =>
/oracle/product/11.2.0/db/lib/libnnz11.so (0x00007f62c83e8000)
libm.so.6 => /lib64/libm.so.6 (0x00007f62c8163000)
libpthread.so.0 => /lib64/libpthread.so.0
(0x00007f62c7f46000)
libnsl.so.1 => /lib64/libnsl.so.1 (0x00007f62c7d2d000)
libaio.so.1 => /lib64/libaio.so.1 (0x00007f62c7b2b000)
/lib64/ld-linux-x86-64.so.2 (0x000000396b200000)
I really have no clue how to proceed.
regards,
Bob
