Trouble maker
IOC
Workstation:
• temp space
• # of possible socket connections
•# of possible processes / user
Network:
• overall network load
• network configuration on IOC
IOC:• # of file descriptors
• utility programs using system resources
• complex locking mechanism in relation to record processing

Avoid Trouble makerWorkstation: => reduce # of users
• temp space
• # of possible socket connections => increase system params
•# of possible processes / user - “ -
Network:
• overall network load => switched networks
• network configuration on IOC => no gateway in boot params
IOC:• # of file descriptors => increase to 256
• utility programs using system resources=> avoid such programs
• complex locking mechanism in relation to record processing=> reduce complexity
