How does COBOL handle multi-user access to VSAM and ISAM files, and what are the potential issues?
- COBOL doesn't support multi-user access to VSAM and ISAM files
- COBOL ensures exclusive file access for each user to prevent conflicts
- COBOL relies on external tools for multi-user file access
- COBOL utilizes file locking mechanisms to allow multiple users simultaneous access
COBOL handles multi-user access to VSAM and ISAM files through file locking mechanisms. Potential issues include contention for locks, leading to delays, and the need for careful coordination to avoid conflicts and data inconsistencies.
