NAME

       slonik - Slony-I command processor

SYNOPSIS

       slonik [filename]

DESCRIPTION

       slonik  is the command processor application that is used to set up and
       modify configurations of Slony-I replication clusters.

OUTLINE

       The slonik command line utility is supposed to be  used  embedded  into
       shell scripts; it reads commands from files or stdin.

       It  reads  a set of Slonik statements, which are written in a scripting
       language with syntax similar to that of SQL, and performs  the  set  of
       configuration changes on the slony nodes specified in the script.

       Nearly  all  of the real configuration work is actually done by calling
       stored procedures  after  loading  the  Slony-I  support  base  into  a
       database.   Slonik  was  created  because  these stored procedures have
       special requirements as to on which particular node in the  replication
       system  they  are  called.  The  absence of named parameters for stored
       procedures makes it rather hard to do this from the  psql  prompt,  and
       psql  lacks  the  ability  to  maintain  multiple connections with open
       transactions to multiple databases.

       The format of the Slonik ‘language’ is very similar to that of SQL, and
       the  parser  is  based  on  a  similar set of formatting rules for such
       things as numbers and strings. Note that slonik is  declarative,  using
       literal  values  throughout. It is anticipated that Slonik scripts will
       typically be generated by scripts, such as  Bash  or  Perl,  and  these
       sorts  of  scripting  languages  already  have  perfectly  good ways of
       managing variables, doing iteration, and such.

       [not available as a man page]].

EXIT STATUS

       slonik  returns  0  to  the  shell if it finished normally. Scripts may
       specify return codes.
