Also removed init for 1 45* last_store_rel_name, as this iw now properly done in 1 46* mrds_dsl_init_res. 1 47* 1 48* 81-07-17 Roger Lackey : added pred_ptr and unused_ptrs. 1 49* 1 50* 82-08-19 Mike Kubicar : added store_vector field. This is needed 1 51* for the conversion to the relation manager. 1 52* 1 53* 82-08-23 Davids: added the relmgr_entries and access_costs 1 54* substructures so that the entries and costs can change 1 55* depending on the type of database that is opened. 1 56* 1 57* 82-09-09 Mike Kubicar : added modify_vector field. This is needed 1 58* since modify uses a different vector type (general) than does store. 1 59* 1 60* 82-09-20 Davids: changed names of (store modify)_vector to 1 61* (store modify)_vector_ptr. Also (delete modify)_tuple_by_id to 1 62* (delete modify)_tuples_by_id. added the element cursor_storage_ptr 1 63* which should be inited to null and will be set by mu_cursor_manager_$get 1 64* during the first call. 1 65* 1 66* 82-09-21 Davids: renamed cursor_storage_ptr to cursor_ptrs_storage_ptr 1 67* since it deals with the pointers to the cursors and not the cursors 1 68* themelves and added the element cursor_storage_area_ptr which points 1 69* to the area where the cursors are kept. 1 70* 1 71* 82-09-22 Davids: renamed the transact_ctl_seg to transactions_needed. 1 72* the transact_ctl_seg always had a value of 0 and really didn't mean 1 73* anything. 1 74* 1 75* 82-09-22 Mike Kubicar : added create_relation, create_index and 1 76* destroy_relation_by_opening to relmgr_entries. They are needed 1 77* by mrds_dsl_define_temp_rel. 1 78* 1 79* 82-09-24 Donna Woodka : added put_tuple to relmgr_entries. It 1 80* is needed by mu_store. 1 81* 1 82* 82-11-12 Davids: changed the declaration of the access_costs from fixed 1 83* bin to float bin since the values are not integers. 1 84* 1 85* 83-02-02 Davids: added the dbc_uid element. This will allow mrds to make 1 86* sure that the dbc_ptr still points to the correct segment. Element was 1 87* added to the end of the structure to allow modules that don't use 1 88* the element to continue to reference the dbcb structure without recompiling. 1 89* 1 90* 83-02-25 Davids: added the concurrency_on and rollback_on elements. These 1 91* are needed so that temp rels can be created with the same file attributes 1 92* as the permanent relations. 1 93* 1 94* 83-05-02 Mike Kubicar : Deleted get_next_search_specification_ptr and 1 95* added the resultant_in_pdir bit. 1 96* 1 97* 83-05-18 Davids: reduced the number of reserved bits to 14 (from 15) and 1 98* added the res_already_made element. 1 99* 1 100* 83-05-24 Mike Kubicar : Updated the relation manager calling sequences. 1 101* 1 102* 83-08-03 Mike Kubicar : Added the element_id_list_segment_ptr and removed 1 103* one of the unused pointers. 1 104* 1 105* 83-09-20 Ron Harvey: Added relmgr_entries.get_population. 1 106* 1 107* 84-08-27 John Hergert: Created compiled_se_info_ptr from unused_ptrs(2) 1 108* leaving unused_ptrs(1). 1 109* 1 110* 85-01-15 Thanh Nguyen: Added the work_area_ptr and removed the last 1 111* unused_ptrs (1). 1 112* 1 113* 85-04-12 Thanh Nguyen: Added user_started_transaction and 1 114* non_shared_to_shared flags. Also added se_transaction_id and some more 1 115* spare ptrs, entries and reserved storages for future enhancement, since 1 116* we changed the saved_res_version from rslt0001 to rslt0002. 1 117* 1 118* 85-07-01 Thanh Nguyen: Added scopes_changed flag. This flag is set by 1 119* common routine of mrds_dsl_set_scope, reset by mrds_dsl_optimize and 1 120* mrds_dsl_gen_srch_prog when building of a new search_vars. 1 121**/ 1 122 1 123 1 124 /* this structure is based on the {unique_name}.mrds.dbcb segment 1 125* that constitutes the non-secure portion of the resultant model that is 1 126* created during the opening of a database. it contains variables that 1 127* are used during the runtime access of the database, and an area 1 128* for evaluation of requests. it points to four other 1 129* segments in the resultant model, {unique_name}.mrds.rdbi, the secure 1 130* portion of the resultant(see mdbm_rm_db_info.incl.pl1), 1 131* {unique_name}.mrds.select, an area for selection expression evaluation, 1 132* {unique_name}.mrds.curdat, and {unique_name}.mrds.stadat, two segments 1 133* used in the elimination of duplicate tuples during a retrieve. 1 134* the dbcb area holds the structure in mdbm_scope_info.incl.pl1 1 135* that is used when the database is using the file scope mechanism 1 136* for concurrency control over file readying. the segment overlayed via 1 137* mrds_dbc.incl.pl1 structure is pointed to and also handles concurrency control, 1 138* across database openings. the pointer to this dbcb structure is kept in a table 1 139* which associates database indexes(returned from a call to dsl_$open), with particular 1 140* opening instances of resultant models.

This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology, Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL and BULL HN Information Systems Inc. to the development of this operating system. Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970), renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for managing computer hardware properly and for executing programs. Many subsequent operating systems incorporated Multics principles. Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
