Summary on use of utilities when adding logical relationships

The following points summarize adding logical relationships with the IMS utilities.

• Counters are increased by counting logical children loaded using an initial load program or, when logically related databases are reorganized, by using DBIL in the control statement.
• Counter problems can be corrected by reorganizing databases. When correcting counter problems, DBIL must be specified in the control statement for the databases involved.
• LCF and LCL pointers are not unloaded and reloaded. They must be recreated by the Prefix Resolution and Update utilities.
• Unless DBIL is specified for all its logical child databases, never specify DBIL in the control statement for a logical parent database.
• To change from symbolic to direct pointers, specify DBIL on the control statement for the logical child database.
