Ingres 9.2 Migration Guide - Actian

Supportability EnhancementsChanges to ANSI Date FeatureThe configuration parameter date_alias (which was introduced in Ingres 2006Release 2 and replaces date_type_alias parameter) controls whether thekeyword DATE used to define the column data type refers to the INGRESDATE(default) or ANSIDATE data type.In this release (Ingres 9.2), the value of date_alias is communicated from theclient to the server. If the client and server have different values fordate_alias, then the server uses the date_alias value set in the config.dat fileon the client. This ensures that the definition of date_alias intended at theclient is preserved in communication to the server.To change the value of date_alias in the config.dat file, use the iisetrescommand. For details on the iisetres command, see the Command ReferenceGuide.Supportability EnhancementsLogging of Verifydb, Chkpdb, and RollforwarddbRecovery tools ckpdb, rollforwarddb, and verifydb now log messages whenthey are executed, stating the database affected and other information.
