GOAL:
What is the maximum sequence value an AI extent file can reach ?
GOAL:
What is the After Image sequence number limit ?
FACT(s) (Environment):
All Supported Operating Systems
Progress 8.x
Progress 9.x
OpenEdge 10.0x
OpenEdge 10.1A
OpenEdge 10.1B
FIX:
AI files have to be restored in the correct sequence. Thus they are given a sequence number which increments by +1 every time an ai extent switch is performed since the last ai begin:
This is aimage file number <n> since the last AIMAGE BEGIN. (1642)
Theoretically, the maximum value for this sequence number is the 32-bit signed integer limit of 2,147,483,647 (2GB).
In practice, Progress can create but not roll forward after-image sequence numbers higher than 65535. The defect that prevented ai files from exceeding 65535 bas been addressed in in the following releases: 10.1C04; 10.2A02 or 10.2B. In these versions, the new limit is 2.147,483,647.
