|
# This is a sample code that contains the user defined user database schema defination.
|
|
# Here is a list of things you can do to add DB tables to xCAT database.
|
|
# 1 Copy this file to /opt/xcat/lib/perl/xCAT_schema directory, rename it
|
|
# to your chosen schema name.
|
|
# 2 Change the word Sample above to be the same as the file name you chose.
|
|
# 3 Do NOT change the variable name "%tabspec".
|
|
# 4 x_lljob and x_llnode are the sample table names.
|
|
# jobid, status, node, jobstatus are the sample column names.
|
|
# Change them to your like. Please make sure all table names start with "x_".
|
|
# Each table must have a 'disable' and comments column.
|
|
# Table names and attributes must be lower case, no case sensitivity is
|
|
# supported.
|
|
# Please do not use SQL reserved words for your table names and column names.
|
|
# Use this site to check the reserved words:
|
|
# http://www.petefreitag.com/tools/sql_reserved_words_checker/
|
|
# 5 Change the keys.
|
|
# 6 Change the data types. For SQLite
|
|
# the default data type is TEXT if not specified.
|
|
# The supported data types are:
|
|
# REAL,CHAR,TEXT,DATE,TIME,FLOAT,BIGINT,DOUBLE,STRING,
|
|
# BINARY,DECIMAL,BOOLEAN,INTEGER,VARCHAR,SMALLINT,TIMESTAMP
|
|
# Please note that SQLight only supports: INTEGER, REAL, TEXT, BLOB.
|
|
# xCAT support MySQL, PostgreSQL and DB2 also, supported data types
|
|
# depend on the database you are using.
|
|
# 7 Change the table descriptions and column descriptions to your like.
|
|
# 8 Restart the the xcatd, the tables will be automatically generated.
|
|
# 9 If you have service nodes, copy all the files to those also and restart
|
|
# the daemon.
|
|
# Note compress and tablespace are only supported for DB2
|
|
# engine is only supported for MySQL
