About "Turkey postpone the switch to DST for 2015 for 2 weeks" and rebooting Exadata Storage Cell without affecting ASM


As you all know, DST is happening at 25/10/2015, but in my country ,Turkey, it is postponed 2 weeks. So all the systems must be patched to handle the situation.  If your database has columns with %TIME ZONE% property, you must apply the db patch. In this post, i will show you some part of the work we done while patching. In Exadata systems, cell nodes and db nodes must be rebooted after the required OS patch applied.
