AIX Reserve Function
AIX Reserved Retry Function
For FX versions 01-XX-61 and earlier, an AIXsystem error will occur when you
use FX to send data to a reserved volume on another system. For FX versions
01-XX-62 and later, you can retry sending data to the reserved volume by
specifying the wait time and retry count for the environment variable of the
other system. FX can send data again when the reserved volume is released
by the other system. The following table shows the AIX reserve functions.
