Fixing Oracle WebCenter Content IBR “error while loading shared libraries: libz.so.1”

After installing and configuring Oracle WebCenter Content (UCM) on 64-bit Linux, you can hit image-processing errors if certain Oracle installer prerequisites were skipped — many 32-bit counterparts such as zlib and zlib-devel aren’t recognized by the installer and application.
The error
When the system tries to create thumbnails — specifically when launching the Image Export utilities — you may see: “error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory.”
The fix
Install the 32-bit zlib libraries:
1yum install --skip-broken zlib.i686 zlib-devel.i686
Even on a 64-bit system, the installer and application require the 32-bit versions. If you saw warnings about missing libraries like libz.so.1 during UCM installation, this typically resolves it.
