Oracle's OCI8 driver binds each named parameter individually via OCIBindByName, making queries with 65 000 parameters dramatically slower than on MySQL or PostgreSQL — slow enough to time out in CI and degrade production LDAP syncs on large installations. Lower maxSlices to 5 for Oracle (5 000 params/query) via a match expression alongside the existing SQLite special-case. SQLite and all other databases are unchanged.
