DBCC_PINNABLE_CACHE_PERCENT Option

0 – 100

50

Option can be set at the database (PUBLIC) or user level. At the database level, the value becomes the default for any new user, but has no impact on existing users. At the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.

Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect at the next execution of sp_iqcheckdb.

The sp_iqcheckdb system stored procedure works with a fixed number of buffers, as determined by this option. By default, a large percentage of the cache is reserved to maximize sp_iqcheckdb performance.

Stored procedures are documented in Reference: Building Blocks, Tables, and Procedures.
