NAME

qstab - Rebuild the qddb Database file contained in RelationDirectory.  

SYNOPSIS

qstab RelationDirectory
 

DESCRIPTION

This program is the first part of the procedure necessary to stabilize a qddb database. Given a RelationDirectory with an existing Database file, Changes and Additions directories, and a Database.keys file, qstab(1) merges all changes and additions into the stable database (file Database).  

SEE ALSO

qkeys(1), qindex(1)  

DIAGNOSTICS

qstab exits with a 0 status on success, 1 otherwise.  

BUGS

Database.keys MUST describe the current state of the Database file. In other words, this program will not work if the Database file is modified without updating the file Database.keys.
