An error may appear when installing iProcess Engine 11.6.1 on RedHat 7.2 as swinstall generates the following:

libnspr4.so is not found
libplc4.so is not found
libplds4.so is not found

TIBCO iProcess Engine (Oracle) 11.6.1 (64-bit) RedHat Enterprise Server 6.6 (64-bit)

The iProcess installer created links under SWDIR/libs to the following libraries (under SWDIR/libs):

    libssl3.so -> /usr/lib64/libssl3.so
    libnss3.so -> /usr/lib64/libnss3.so
    libnspr4.so -> /usr/lib64/libnspr4.so
    libsoftokn3.so -> /usr/lib64/libsoftokn3.so
    libplc4.so -> /usr/lib64/libplc4.so
    libplds4.so -> /usr/lib64/libplds4.so 
 
The iProcess Installer checks to see if the above libraries exists under /usr/lib64 . If the library exists then the link is created.
 
The installer messages:

    libnspr4.so is not found
    libplc4.so is not found
    libplds4.so is not found

indicate that the three libraries do not exist under /usr/lib64  . The installer is unable to create the links.
 
The following libraries were not found on the server under /usr/lib64:

    /usr/lib64/libnspr4.so
    /usr/lib64/libplc4.so
    /usr/lib64/libplds4.so
 
In a standard RedHat Enterprise Linux server the three libraries reside under /lib64 with links under /usr/lib64,  these links were missing on the server.

The resolution is to create the links as root using the following commands and then re-run the iProcess installer:

cd /usr/lib64
ln -s ../../lib64/libnspr4.so libnspr4.so
ln -s ../../lib64/libplc4.so libplc4.so
ln -s ../../lib64/libplds4.so libplds4.so
