ResourceStatusDB

ResourceStatusDB: This module provides definition of the DB tables, and methods to access them.

Written using sqlalchemy declarative_base

For extending the ResourceStatusDB tables:

  1. In the extended module, call:

from DIRAC.ResourceStatusSystem.DB.ResourceStatusDB import rmsBase, TABLESLIST, TABLESLISTWITHID TABLESLIST = TABLESLIST + [list of new table names] TABLESLISTWITHID = TABLESLISTWITHID + [list of new table names]

  1. provide a declarative_base definition of the tables (new or extended) in the extension module

class DIRAC.ResourceStatusSystem.DB.ResourceStatusDB.ElementStatusBase

Bases: object

Prototype for tables.

columnsOrder = ['Name', 'StatusType', 'Status', 'Reason', 'DateEffective', 'TokenExpiration', 'ElementType', 'LastCheckTime', 'TokenOwner', 'VO']
dateeffective = Column('DateEffective', DateTime(), table=None, nullable=False)
elementtype = Column('ElementType', String(length=32), table=None, nullable=False, server_default=DefaultClause('', for_update=False))
fromDict(dictionary)

Fill the fields of the AccountingCache object from a dictionary

Parameters

dictionary – Dictionary to fill a single line

lastchecktime = Column('LastCheckTime', DateTime(), table=None, nullable=False, server_default=DefaultClause('1000-01-01 00:00:00', for_update=False))
name = Column('Name', String(length=64), table=None, primary_key=True, nullable=False)
reason = Column('Reason', String(length=512), table=None, nullable=False, server_default=DefaultClause('Unspecified', for_update=False))
status = Column('Status', String(length=8), table=None, nullable=False, server_default=DefaultClause('', for_update=False))
statustype = Column('StatusType', String(length=128), table=None, primary_key=True, nullable=False, server_default=DefaultClause('all', for_update=False))
toList()

Simply returns a list of column values

tokenexpiration = Column('TokenExpiration', DateTime(), table=None, nullable=False, server_default=DefaultClause('9999-12-31 23:59:59', for_update=False))
tokenowner = Column('TokenOwner', String(length=16), table=None, nullable=False, server_default=DefaultClause('rs_svc', for_update=False))
vo = Column('VO', String(length=64), table=None, primary_key=True, nullable=False, server_default=DefaultClause('all', for_update=False))
class DIRAC.ResourceStatusSystem.DB.ResourceStatusDB.ElementStatusBaseWithID

Bases: DIRAC.ResourceStatusSystem.DB.ResourceStatusDB.ElementStatusBase

Prototype for tables

This is almost the same as ElementStatusBase, with the following differences: - there’s an autoincrement ID column which is also the primary key - the name and statusType components are not part of the primary key

columnsOrder = ['ID', 'Name', 'StatusType', 'Status', 'Reason', 'DateEffective', 'TokenExpiration', 'ElementType', 'LastCheckTime', 'TokenOwner', 'VO']
dateeffective = Column('DateEffective', DateTime(), table=None, nullable=False)
elementtype = Column('ElementType', String(length=32), table=None, nullable=False, server_default=DefaultClause('', for_update=False))
fromDict(dictionary)

Fill the fields of the AccountingCache object from a dictionary

Parameters

dictionary – Dictionary to fill a single line

id = Column('ID', BigInteger(), table=None, primary_key=True, nullable=False)
lastchecktime = Column('LastCheckTime', DateTime(), table=None, nullable=False, server_default=DefaultClause('1000-01-01 00:00:00', for_update=False))
name = Column('Name', String(length=64), table=None, nullable=False)
reason = Column('Reason', String(length=512), table=None, nullable=False, server_default=DefaultClause('Unspecified', for_update=False))
status = Column('Status', String(length=8), table=None, nullable=False, server_default=DefaultClause('', for_update=False))
statustype = Column('StatusType', String(length=128), table=None, nullable=False, server_default=DefaultClause('all', for_update=False))
toList()

Simply returns a list of column values

tokenexpiration = Column('TokenExpiration', DateTime(), table=None, nullable=False, server_default=DefaultClause('9999-12-31 23:59:59', for_update=False))
tokenowner = Column('TokenOwner', String(length=16), table=None, nullable=False, server_default=DefaultClause('rs_svc', for_update=False))
vo = Column('VO', String(length=64), table=None, nullable=False, server_default=DefaultClause('all', for_update=False))
