A little old, but I felt the pain in my heart… You will feel it too, I think…
We already have faced situations like this to big envs, specially this migration from 220.127.116.11 to 11gR2… Latch mutex including…
It’s long, but it’s good.
Do you know the difference?
current_date(): Only give you the date.
now(): Datetime when the statement,procedure etc… started.
sysdate(): Current datetime.
Take a look between the functions now() and sysdate() after executing sleep of 5 seconds…:
SQL> select current_date(),now(),sysdate(),SLEEP(5),now(),sysdate();
"2016-03-24";"2016-03-24 16:00:43";"2016-03-24 16:00:43";"2016-03-24 16:00:43";"2016-03-24 16:00:48"
Supposing you are in a server shell and don’t know if you machine is virtualized (a VM)?
One way to check that (supposing VMWare as hypervisioning solution) is:
[root@mydbsrvr ~]# dmidecode | grep -i vmware
Manufacturer: VMware, Inc.
Product Name: VMware Virtual Platform
Serial Number: VMware-xx xx xx xx xx xx xx xx-xx xx xx xx xx xx xx xx
Description: VMware SVGA II
If you had an answer like this, yes, it’s a VM. 🙂
Take a look here.
Quick post just to tell you that. 🙂

The symptoms includes this two key factors:
– presence of CONTAINS clause
– use of bind variables
