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 needed to start the database server.
Use the VPCLASS configuration parameter with the encrypt keyword to configure encryption VPs. For example, 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 chapter in the IBM Informix Dynamic Server Administrator's Reference. For more information on column-level encryption, see Using Column-Level Encryption.
