Encrypt virtual processors
Use the VPCLASS configuration parameter with the encrypt
keyword
to configure encryption VPs.
If the encrypt
option of the VPCLASS parameter
is not defined in the onconfig configuration
file, the database server starts one ENCRYPT VP the first time that
any encryption or decryption functions defined for column-level encryption
are called. You can define multiple ENCRYPT VPs if necessary to decrease
the time required to start the database server.
To add five ENCRYPT VPs, add information in the onconfig file
as follows:
VPCLASS encrypt,num=5
You can modify the same information using the onmode utility,
as follows:
onmode -p 5 encrypt
For more information, see the configuration parameters and the onmode utility topics in the Informix® Administrator's Reference. For more information about column-level encryption, see the Informix® Security Guide.
