As such, it's reasonable to suggest that our randomised script for allocating primary/secondary on a client isn't as random as we think.</FONT></SPAN></DIV> <DIV><SPAN class=261564008-01062015><FONT size=2 face=Arial></FONT></SPAN> </DIV> <DIV><SPAN class=261564008-01062015><FONT size=2 face=Arial>Might it also be possible that due to the hard coding option we had to take, our clients end up failing over to a certain server, but then never failing back when the primary returns? Under maintenance we generally patch and reboot the odd numbered servers, followed by the even servers once the odd servers are back.</FONT></SPAN></DIV> <DIV><SPAN class=261564008-01062015><FONT size=2 face=Arial></FONT></SPAN> </DIV> <DIV><SPAN class=261564008-01062015><FONT size=2 face=Arial>Thanks</FONT></SPAN></DIV> <DIV><SPAN class=261564008-01062015><FONT size=2 face=Arial></FONT></SPAN> </DIV> <DIV><SPAN class=261564008-01062015><FONT size=2 face=Arial>Duncan</FONT></SPAN></DIV><br clear="both"> This message has been checked for viruses and spam by the Virgin Money email scanning system powered by Messagelabs.<BR> <BR> This e-mail is intended to be confidential to the recipient.
