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
