Notes

Heartbeat Interval100,000 microsecondsNo Limit (ULONG_MAX)

1,000,000 microseconds

Node Timeout200,000 microsecondsNo Limit (ULONG_MAX)

2,000,000 microseconds

The Node Timeout value must be at least twice the Heartbeat Interval

AutoStart Timeout60,000,000 microsecondsNo Limit (ULONG_MAX)

600,000,000 microseconds

Network Polling Interval100,000 microsecondsNo Limit (ULONG_MAX)

Maximum Configured Packages0150150

 

ULONG_MAX is a number equal to 4,294,967,295, which is therefore a practical limit.

Table I-2 “Minimum and Maximum Values of Package Configuration Parameters” shows the range of possible values for package configuration parameters.

Notes

Run Script Timeout

10 seconds4294 seconds if a non-zero value is specified

0 (NO_TIMEOUT)

This is a recommended value.

Halt Script Timeout10 seconds4294 seconds if a non-zero value is specified

0 (NO_TIMEOUT)

This is a recommended value, but note that the Halt Timeout value must be greater than the sum of all Service Timeout values

Service Halt Timeout

1 secondNo Limit (ULONG_MAX)

300 seconds (5 minutes)
