153. What are the two phases of block coordination?
There are two phases of block coordination: the clear phase and the population phase. During, the clear phase, Oracle Forms navigates internally to the detail block and flushes the obsolete detail
records. During the population phase, Oracle Forms issues a SELECT statement to repopulate the detail block with detail records associated with the new master record. These operations are
accomplished through the execution of triggers.

181. what are difference between post database commit and post-form commit?
Post-form commit fires once during the post and commit transactions process, after the database commit occurs. The post-form-commit trigger fires after inserts, updates and deletes have been posted to the database but before the transactions have been finalized in the issuing the command. The post-database-commit trigger fires after oracle forms issues the commit to finalized transactions.
182. What are the different display styles of list items?
Pop_listText_listCombo box

185. What are parameters?
Parameters provide a simple mechanism for defining and setting the
valuesof inputs that are required by a form at startup. Form parameters are variables of type char,number,date that you define at design time.
