The idsxmlvp virtual processor class

The XML functions that HCL Informix® provides run in a virtual processor class named idsxmlvp.

The idsxmlvp virtual processor is created automatically the first time you use an XML function. If you want to increase the number of idsxmlvp virtual processors, use one of the following methods:

Add the following line to your onconfig file, substituting n with the number of virtual processors you want to start, and restart the database server: VPCLASS idsxmlvp,num=n
As user informix, run the following command while the database server is running, substituting n with the number of virtual processors you want to start: onmode -p +n idsxmlvp
