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 HCL Informix® Administrator's Reference. For more information about column-level encryption, see the HCL Informix Security Guide.
