+
+Please note that SQLite both versions 2 and 3 are not network enabled,
+which means that they must be linked into the Director rather than accessed
+by the network as MySQL and PostgreSQL are. This has two consequences:
+\begin{enumerate}
+\item SQLite cannot be used in the {\bf bweb} web GUI package.
+\item If you use SQLite, and your Storage daemon is not on the same
+machine as your Director, you will need to transfer your database
+to the Storage daemon's machine before you can use any of the SD tools
+such as {\bf bscan}, ...
+\end{enumerate}
+
+\section{Installing and Configuring SQLite -- Phase I}
+\index[general]{Phase I!Installing and Configuring SQLite -- }
+\index[general]{Installing and Configuring SQLite -- Phase I }
+
+If you use the {\bf ./configure \verb:--:with-sqlite} statement for configuring {\bf
+Bacula}, you will need SQLite version 2.8.16 or later installed. Our standard
+location (for the moment) for SQLite is in the dependency package {\bf
+depkgs/sqlite-2.8.16}. Please note that the version will be updated as new
+versions are available and tested.
+
+Installing and Configuring is quite easy.
+
+\begin{enumerate}
+\item Download the Bacula dependency packages
+\item Detar it with something like:
+
+ {\bf tar xvfz depkgs.tar.gz}
+
+ Note, the above command requires GNU tar. If you do not have GNU tar, a
+ command such as:
+
+ {\bf zcat depkgs.tar.gz | tar xvf -}
+
+ will probably accomplish the same thing.
+
+\item {\bf cd depkgs}
+
+\item {\bf make sqlite}
+
+\end{enumerate}
+
+
+Please note that the {\bf ./configure} used to build {\bf Bacula} will need to
+include {\bf \verb:--:with-sqlite} or {\bf \verb:--:with-sqlite3} depending
+one which version of SQLite you are using. You should not use the {\bf
+\verb:--:enable-batch-insert} configuration parameter for Bacula if you
+are using SQLite version 2 as it is probably not thread safe. If you
+are using SQLite version 3, you may use the {\bf \verb:--:enable-batch-insert}
+configuration option with Bacula, but when building SQLite3 you MUST
+configure it with {\bf \verb:--:enable-threadsafe} and
+{\bf \verb:--:enable-cross-thread-connections}.
+
+By default, SQLite3 is now run with {\bf PRAGMA synchronous=OFF} this
+increases the speed by more than 30 time, but it also increases the
+possibility of a corrupted database if your server crashes (power failure
+or kernel bug). If you want more security, you can change the PRAGMA
+that is used in the file src/version.h.
+
+
+At this point, you should return to completing the installation of {\bf
+Bacula}.
+
+
+\section{Installing and Configuring SQLite -- Phase II}
+\label{phase2}
+\index[general]{Phase II!Installing and Configuring SQLite -- }
+\index[general]{Installing and Configuring SQLite -- Phase II }
+
+This phase is done {\bf after} you have run the {\bf ./configure} command to
+configure {\bf Bacula}.
+
+{\bf Bacula} will install scripts for manipulating the database (create,
+delete, make tables etc) into the main installation directory. These files
+will be of the form *\_bacula\_* (e.g. create\_bacula\_database). These files
+are also available in the \lt{}bacula-src\gt{}/src/cats directory after
+running ./configure. If you inspect create\_bacula\_database, you will see
+that it calls create\_sqlite\_database. The *\_bacula\_* files are provided
+for convenience. It doesn't matter what database you have chosen;
+create\_bacula\_database will always create your database.
+
+At this point, you can create the SQLite database and tables:
+
+\begin{enumerate}
+\item cd \lt{}install-directory\gt{}
+
+ This directory contains the Bacula catalog interface routines.
+
+\item ./make\_sqlite\_tables
+
+ This script creates the SQLite database as well as the tables used by {\bf
+ Bacula}. This script will be automatically setup by the {\bf ./configure}
+ program to create a database named {\bf bacula.db} in {\bf Bacula's} working
+ directory.
+\end{enumerate}
+
+\section{Linking Bacula with SQLite}
+\index[general]{SQLite!Linking Bacula with }
+\index[general]{Linking Bacula with SQLite }
+
+If you have followed the above steps, this will all happen automatically and
+the SQLite libraries will be linked into {\bf Bacula}.
+
+\section{Testing SQLite}
+\index[general]{SQLite!Testing }
+\index[general]{Testing SQLite }
+
+We have much less "production" experience using SQLite than using MySQL.
+SQLite has performed flawlessly for us in all our testing. However,
+several users have reported corrupted databases while using SQLite. For
+that reason, we do not recommend it for production use.
+
+If Bacula crashes with the following type of error when it is started:
+\footnotesize
+\begin{verbatim}
+Using default Catalog name=MyCatalog DB=bacula
+Could not open database "bacula".
+sqlite.c:151 Unable to open Database=/var/lib/bacula/bacula.db.
+ERR=malformed database schema - unable to open a temporary database file
+for storing temporary tables
+\end{verbatim}
+\normalsize
+
+this is most likely caused by the fact that some versions of
+SQLite attempt to create a temporary file in the current directory.
+If that fails, because Bacula does not have write permission on
+the current directory, then you may get this errr. The solution is
+to start Bacula in a current directory where it has write permission.
+
+
+\section{Re-initializing the Catalog Database}
+\index[general]{Database!Re-initializing the Catalog }
+\index[general]{Re-initializing the Catalog Database }
+
+After you have done some initial testing with {\bf Bacula}, you will probably
+want to re-initialize the catalog database and throw away all the test Jobs
+that you ran. To do so, you can do the following:
+
+\footnotesize
+\begin{verbatim}
+ cd <install-directory>
+ ./drop_sqlite_tables
+ ./make_sqlite_tables
+\end{verbatim}
+\normalsize
+
+Please note that all information in the database will be lost and you will be
+starting from scratch. If you have written on any Volumes, you must write an
+end of file mark on the volume so that Bacula can reuse it. Do so with:
+
+\footnotesize
+\begin{verbatim}
+ (stop Bacula or unmount the drive)
+ mt -f /dev/nst0 rewind
+ mt -f /dev/nst0 weof
+\end{verbatim}
+\normalsize
+
+Where you should replace {\bf /dev/nst0} with the appropriate tape drive
+device name for your machine.
