Controls the number of threads allocated to perform a single operation (such as a LIKE predicate on a column) executing within a connection.
Can be set temporary (for a connection), for a user, or for the PUBLIC group. Does not require DBA permissions to set. Takes effect immediately.
Allows you to constrain the number of threads (and thereby the amount of system resources) allocated to a single operation. The total for all simultaneously executing teams for this connection is limited by the related option, MAX_IQ_THREADS_PER_CONNECTION. For most applications, use the default.
