LicGen is a hypothetical license generator that consumes a DSL to produce license files.
ssqexe is the validation engine that checks licenses at runtime.
This paper describes the process of updating LicGen and ssqexe to a newer DSL version (“L updated”).
Run a sample DSL script that includes SQL operations: dsls licgen ssqexe l updated

CONNECT TO production_db;
SELECT COUNT(*) FROM licensed_features WHERE status='active';
If the license is invalid, ssqexe should return error code 0xL7 (License outdated). If the license is invalid, ssqexe should return
Obtain the new licgen and ssqexe binaries from the official vendor. Verify checksums. If the license is invalid
