How objects are stored

Objects and their definitions are stored in definition bases. The first time TOM starts using a newly allocated registry data set, a default object definition base is created, named DEFAULT and a default calendar definition base is created, named DEFAULTCAL. Only one definition base of each type can be active for a TOMPLEX at any one time.

You can create multiple definition bases to address different situations, such as:

  • A test definition base to use temporarily when making a large number of changes

  • A disaster-recovery definition base to quickly re-establish a functioning system

  • Alternative definition bases to use for weekend activity or to meet other recurring system requirements

Consider enclosing an object name or set name within single quotation marks (’) when using TOMEXEC API functions or TOM console commands, in addition to these naming restrictions:

  • Object names and set names are up to 64 characters and cannot contain a forward slash (/), a backward slash (/), a vertical bar (|), a cent sign (¢ ), a left pointed bracket (<), a right pointed bracket (>), an ampersand (&), a single quotation mark ('), a double quotation mark ('), an asterisk (*), a question mark (?), a logical not sign (¬), a split vertical bar (¦), or a plus sign (+).

  • When you specify an object or set name as part of your syntax for a TOMEXEC function, you must enclose the name within single quotation marks (') if it contains lowercase characters, spaces, or non alphanumeric characters.
