Locks and Deadly Locks

Locks

Locks are normal.

GO CMDLCK

RPG Reads an entire record into a program which will be updating the record on some account, item, customer, order, whatever. Different programs in the hands of different users might be updating different fields such as:

• Inventory Totals
• $ Financials
• Alphabetical descriptions

We want to avoid conflicts between the different people who might be updating different fields in the same records at the same time.

Deadly Locks

Deadly Locks are a symptom of poor software design and/or poor implementation practices.
