Hi,
You can get ” ./ggsci: error while loading shared libraries: libnnz18.so: cannot open shared object file: No such file or directory” error during Goldengate 19c installation for 18c RDBMS.
When you login Goldengate via ggsci, you can get the following error.
./ggsci: error while loading shared libraries: libnnz18.so: cannot open shared object file: No such file or directory
To solve this problem, create soft link for the libnnz18.so package as follows.
ln -s /u01/app18c/lib/libnnz18.so libnnz18.so
After creating this soft link, you can get the following error also.
Create soft link for libclntsh.so.18.1 also.
./ggsci: error while loading shared libraries: libclntsh.so.18.1: cannot open shared object file: No such file or directory
ln -s /u01/app18c/lib/libclntsh.so.18.1 libclntsh.so.18.1
After creating this soft links, you can get the following error also.
./ggsci: error while loading shared libraries: libclntshcore.so.18.1: cannot open shared object file: No such file or directory
ln -s /u01/app18c/lib/libclntshcore.so.18.1 libclntshcore.so.18.1
Once you created the soft links, you can login Goldengate as follows.
