21Documentation for the pykota-postgresql.sql script :
22----------------------------------------------------
23
24This script is to be used to create an empty Quota Storage
25DataBase using PostgreSQL as a backend.
26
27If you have already installed PyKota, and have datas in your
28Quota Storage DataBase, you may prefer to skip this section
29and read the next one.
30
31        - edit the pykota-postgresql.sql file and modify the passwords on
32          the 'CREATE USER' lines.
33
34        - Launch the psql frontend and connect to the
35          database template1 as a PostgreSQL administrator
36          (i.e. the postgres user) :
37
38          as user 'root' :
39
40            # su - postgres
41
42          you're now user 'postgres', then continue with :
43
44            $ psql -f pykota-postgresql.sql template1
45
46          or depending on your settings you may prefer :
47
48            $ psql -h localhost -U postgres -f pykota-postgresql.sql template1
49
50        - If no error message appears, your PostgreSQL PyKota storage
51          is now ready for use. NB : a lot of NOTICE messages might appear,
52          this is perfectly normal.
53
54        - In ~pykota/pykota.conf, ensure that the following lines
55          are present and unique inside the [global] section :
56
57            storagebackend : pgstorage
58            storageserver : localhost
59            storagename : pykota
60            storageuser : pykotauser
61            storageuserpw : readonlypw
62
63            NB : replace 'readonlypw' with the password you chose
64            for user 'pykotauser' when you modified pykota-postgresql.sql
65
66        - In ~pykota/pykotadmin.conf ensure that the following lines
67          are present and unique inside the [global] section :
68
69            storageadmin : pykotaadmin
70            storageadminpw : readwritepw
71
72            NB : replace 'readwritepw' with the password you chose
73            for user 'pykotaadmin' when you modified pykota-postgresql.sql
74
75        - IMPORTANT : if your database is not located on the print server,
76          replace 'localhost' in the lines above with your database server's
77          hostname or IP address. If your database server doesn't listen on
78          its standard port, add the port number at the end of the hostname
79          with a colon to separate the hostname from the port.
80          See pykota/conf/pykota.conf.sample for examples.

84Upgrade scripts :
85
86  DON'T DO ANYTHING IF THIS IS YOUR FIRST INSTALLATION
87  OF PYKOTA.
88
89  Some scripts to upgrade old PyKota databases to the new
90  database schema are included. You may have to run all
91  of them or only some of them, depending on your
92  version of PyKota. Usually running them several times, for
93  example if you used several different development versions
94  of PyKota, won't do any harm.
95
96  If you're connected as user 'root', you have to be user 'postgres'
97  instead :
98
99            # su - postgres
100
101  You're now user 'postgres', then continue the upgrade by following
102  the instructions below, depending on the version you actually use :
103
104  * An SQL script to upgrade a 1.22 PyKota Storage DataBase to
105    1.23 is included. Launch it this way on the Quota Storage Server :
106
107        $ psql -U postgres pykota
108        pykota=# \i upgrade-to-1.23.sql
109        pykota=# \q
110        $
111
112    This script adds many fields to existing tables, and a table to
113    manage billing codes.
114
115  * An SQL script to upgrade a 1.20 PyKota Storage DataBase to
116    1.21 is included. Launch it this way on the Quota Storage Server :
117
118        $ psql -U postgres pykota
119        pykota=# \i upgrade-to-1.21.sql
120        pykota=# \q
121        $
122
123    This script adds many fields to existing tables, and also adds
124    some tables in indexes.
125
126  * An SQL script to upgrade a 1.18 PyKota Storage DataBase to
127    1.19 is included. Launch it this way on the Quota Storage Server :
128
129        $ psql -U postgres pykota
130        pykota=# \i upgrade-to-1.19.sql
131        pykota=# \q
132        $
133
134    This script adds a field to the print job history. The field that
135    is added is : hostname
136
137  * An SQL script to upgrade a pre-1.16 PyKota Storage DataBase to
138    1.16 is included. Launch it this way on the Quota Storage Server :
139
140        $ psql -U postgres pykota
141        pykota=# \i upgrade-to-1.16.sql
142        pykota=# \q
143        $
144
145    This script adds some fields to the print job history, so that
146    more complete information will be known. The fields that
147    are added are : jobprice, filename, title, copies and print
148    command options. Also some indexes are created to speed things up.
149
150What is below is for historical reasons only, real people don't use
151such old beasts, and YOU SHOULDN'T EITHER !
152
153  * An SQL script to upgrade a pre-1.14 PyKota Storage DataBase to
154    1.14 is included. Launch it this way on the Quota Storage Server :
155
156        $ psql -U postgres pykota
157        pykota=# \i upgrade-to-1.14.sql
158        pykota=# \q
159        $
160
161    This script adds an "email" field for each user. This field, if not
162    NULL, is used as the email address of the user when sending warning
163    messages in case he is over quota.
164
165  * An sql script to upgrade a pre-1.01 PyKota Quota Storage DataBase to
166    1.01 is still included for historical reasons. PLEASE DON'T USE IT !
167
168  * If you are already running an old version of PyKota (<1.03) and
169    want to upgrade to 1.03, YOU HAVE TO RUN the
170    upgrade-from-before-1.03.py shell script. NOT LAUNCHING THIS SCRIPT
171    WILL CAUSE PYKOTA TO STOP WORKING ! PLEASE NEVER RUN THIS SCRIPT IF
172    YOUR EXISTING VERSION OF PYKOTA IS ALREADY 1.03 OR HIGHER.
