Guardian RWEP string. The default setting secures all access to the files

to the user to allow network access without encountering a Guardian

security error 48.

QFLUSHDELAY seconds

4.090 300 0 32767 No

This parameter is the length of time, in seconds, the Queue Manager

waits before flushing data to disk and saving the restart file information. A

value of 0 means that time-based flushing is disabled. The default value is

5 minutes.

Note that there are other factors that may cause the data to be flushed

and the restart file written. This also occurs when the flush limit (specified

by QFLUSHLIMIT) of messages is exceeded. Flushing also occurs

whenever a file is filled, becomes available because the Consumer’s

restart point has moved beyond the end of the file, or when the Queue

Manager is shutdown.

More frequent flushing will mean less data to be resent on startup at the

expense of additional I/Os to the disk.
