Rebuild databases not involved in synchronization or replication

The following procedures should be used only if your database is not involved in synchronization or replication.

 To rebuild a database not involved in synchronization or replication (command line)

  1. Run the dbunload utility, specifying one of the following options:

    To do this... Use this option... Example
    Rebuild to a new database -an 
    dbunload -c 
"DBF=demo.db;UID=DBA;PWD=sql" 
   -an DemoBackup.db
    Reload to an existing database -ac 
    dbunload -c 
"DBF=demo.db;UID=DBA;PWD=sql" 
   -ac "UID=DBA;PWD=sql;DBF=mynewdemo.db"
    Replace an existing database -ar 
    dbunload -c 
"DBF=demo.db;UID=DBA;PWD=sql" 
   -ar

    If you use one of these options, no interim copy of the data is created on disk, so you do not need to specify an unload directory on the command line. This provides greater security for your data. The -ar and -an options should also execute more quickly than the Unload Database Wizard in Sybase Central, but -ac is slower than the Unload Database Wizard.

  2. Shut down the database and archive the transaction log before using the reloaded database.
