#################################################################################
# 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.
#      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.
#

# The following %defspec is OPTIONAL. You only need to define it

# Note: The xCAT database accessting commands such as
#       tabdump, chtab, gettab, nodels, nodeadd, nodech, etc. 
#       still work without it.
# 
#       Please make sure that any new object name and attribute name
#       should start with "x_".
