Installation notes

This update is provided as an RPM package that can easily be installed onto a running system by using this command:
rpm -Uvh libica-z990.rpm
Applications using libica can make use of the new hardware when the old /usr/lib/libica (for 64-Bit /usr/lib64/libica) is replaced with /opt/libica-z990/lib/libica.so.
On a 31-bit system you can do this with the following commands:
cd /usr/lib mv libica.so.0.0.0 libica.so.0.0.0.old cp -p /opt/libica-z990/lib/libica.so libica.so.0.0.0
On a 64-bit system you have to use the above commands and the following commands:
cd /usr/lib64 mv libica.so.0.0.0 libica.so.0.0.0.old cp -p /opt/libica-z990/lib64/libica.so libica.so.0.0.0
To activate openCryptoki 2.1.3 several configuration files have to be replaced.
First rename the original files:
mv /etc/pkcs11 /etc/pkcs11.old mv /usr/lib/pkcs11 /usr/lib/pkcs11.old mv /usr/sbin/pkcsslotd /usr/sbin/pkcsslotd.old
Now link the new files via softlink:

 ln -s /opt/openCryptoki-z990/etc/pkcs11 /etc/pkcs11 ln -s /opt/openCryptoki-z990/lib/pkcs11 /usr/lib/pkcs11 ln -s /opt/openCryptoki-z990/sbin/pkcsslotd /usr/sbin/pkcsslotd
