The BMEND utility routine performs the function of updating and reconstructing a database within the general framework of the UDS/SQL security concept (see the “Database Operation” manual).
BMEND can be used to update the entire database or to update individual or selected realms with one or more ALOG files. It can be applied on both the original database and the shadow database as well as detached realms.
The database can be updated using ALOG files with the UPDATE-DATABASE statement.
The BMEND statement SHOW-LOG-INFORMATION shows which ALOG files must be specified when updating individual realms in order to make their state consistent with that of the entire database. In other words, you must make these ALOG files available for the update.
You are also provided with information on whether a logging gap exists in the sequence of ALOG files and whether any ALOG file was terminated in an inconsistent state. In such cases, updates can only be applied until that point in time. Later it is only possible using backup.
