from last two weeks we are receiving rhe below database alert on our second NODE (RAC ENV).
Global cache Average CR get time " is at .61789
Threshold is set on >.5 (M.Second).
me to figure this out because i really dont know the nature of this alert. what value i can set for the warning threshold.
I have a table with products (xPRODUCT), dates (xDATE) and parameters (xPARAMETER). Now I want to calculate the rolling 12 month average of the parameters over all products for all dates. I tried this:
select xDATE,
avg(xPARAMETER) over ( order by xDATE
range between numtodsinterval(365,'day')
preceding and current row )
[Code]....
... but this does not work. How can I do this?
how to calculate the average of the time in th e HH:MM:SS format stored database table.. column contains hundreds of time values and need to table the avergae of it

I'm trying to install 2 nodes oracle RAC 11gR2 on SLES11. I configured DNS for public,virtual, private and scan IPs. when I check with nslookup, everything seems ok. but when I run runcluvfy.sh, it says that:
" PRVF-5636 : The DNS response time for an unreachable node exceeded 15000 ms on following nodes: rac1,rac2"
How can I decrease the response time?
i'm keep on getting below error every morning in my Database.this indicate in Grid control every morning.
Metrics "Database Time Spent Waiting (%)" is at 34.336 for event class "Concurrency"

i need to know, this is something that i should consider as a critical warning and how can i solve this .
why CPU utilization is high(99%) on one server in 2 node RAC at every time. On the other server it is very low.

How To Calculate Average in Forms 6i for example a summary column named (Amount = 5000) and i want to calculate 15% average of this amount i want to calculate it like summary column .

I have a table with the following format and data
Serial no exp_Date exp_type exp_amount
1 01-nov-2012 Rent 10000
2 02-nov-2012 gas 250
3 02-nov-2012 insurance 9500
.
.
.
I want to create a sql output for a yearly view in the format
exp_type JAN FEB MAR APR ..... NOV DEC TOTAL AVERAGE PROJECTED
Rent 10000 10000 10000 10000 10000 10000 120000 10000 120000
gas 250 250 250 250 250 250 3000 250 3000
.
.
Now a couple of things in this
1. the average gives the average for the year, so lets say its start of 2013 and we are in feb, there will not be any values for the remaining months, so it should do the average for that exp_type for Jan and Feb based on the exp_amount entered against that type and show what is the expected average. Similary, projected will that average amount and mulitply it by 12 to show the exp amount expected based on current expenses
I was able to come up with the following sql to get the sum based on months, was not sure about average, total and projected
SELECT exp_type
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Jan' THEN exp_amt END) AS Jan
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Feb' THEN exp_amt END) AS feb
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Mar' THEN exp_amt END) AS Mar
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Apr' THEN exp_amt END) AS Apr
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'May' THEN exp_amt END) AS May
[Code]....
getting the correct avg, total and projected fields also in the same sql?

How can i write a query so that i takes the average of students in each room and display the output? I need to write a query so that it also picks up any new rooms and students added. Average is sum of total students in room by number of times each room is specified.
eg: A1 is listed 3 times a the result would be 10+20+15 divided by 3.
A1 B1 B2 C115 15 20 15
I have to procedure that computes number of project, and average working hours of employees where employee id is passed as a parameter to the procedure.

Record can be uniquely identified by columns ID, PRODUCT and OFFICE. I want to calculate average for each date considering the same record does not exists earlier i.e. I want to consider the latest vote while calculating average. E.g.
Average till date 1/1/2011 is Avg (2, 4, 3) = 3 (as no repeating vote value exists)
Average till date 2/1/2011 is Avg (4, 3, 5, 3) = 3.75 (excluding vote value 2 as 122_UK_LONDON was provided his vote earlier, so considered latest vote value i.e. 5)
Average till date 3/1/2011 is Avg (3, 5, 3, 6, 5, 8 ) = 5 (excluding vote value 2 for 122_UK_LONDON and vote value 4 for 967_Europe_London)

I have a problem related with hierarchical queries, I have this tree.
- a
/
b c
/ |
d e fI need to calculate an average per node but using always the child's results for example: Only leafs will have values:
d = 10
e = 20
f = 30
c = 40So the expected result is:
d = 10
e = 20
f = 30
c = 40
b = (10(d) + 20(e) + 30(f)) / 3 (number of child nodes) = 20
a = (20(b) + 40(c)) / 2 (number of child nodes) = 30.
I have tried with recursive queries, hierarchical queries, I guess it's possible with model too but I can't produce the exact results that I need. Maybe in fact there is a very simple solution but I cannot figure it.
Here is an auxiliary WITH that you can use to start your tests:
WITH tree AS
(
SELECT 'd' child, 'b' parent FROM dual UNION ALL
SELECT 'e' child, 'b' parent FROM dual UNION ALL
SELECT 'f' child, 'b' parent FROM dual UNION ALL
SELECT 'b' child, 'a' parent FROM dual UNION ALL
SELECT 'c' child, 'a' parent FROM dual UNION ALL
SELECT 'a' child, null parent FROM dual

I've got values for each workday of month in table. Chief said we don't load values of weekend because of space and time economy. Weekend value is copy of last workday. How do I count average for month in this case? Technical task in Excel worksheet consist of each day of month, so average value is 14 689 262,86. I should get the same result in my query. My example below shows values, 0 is workday (present in table), 1 is weekend (absent in table)..

My problem is only on Some Saturday's my Oracle server's Load average goes high (more than 300 ).
-- oracle version 11.2.0.1.0
-- runs on Sun solaris 10
-- Sun fire V 440
-- Sun storEdge 3315 connected to the server.
Same setup is working find with higher volumes without any problem but only on saturday's, that too not on all saturdays, some specific saturdays the load average goes high.
At the time nothing will be processed from the application side and the cpu utilisation goes high upto 95 %.

I´m monitoring a 11g database with OEM. I have a couple of questions regarding the Average Active Sessions chart:
- What does the line 'CPU core' means? The DB is running in a virtual server with 8 CPUs. However, the line 'CPU core' is in 1. Does it mean that Oracle is just using 1 CPU?
- What represents the '99th percentile' line? The chart shows several sessions above that line, something is not working well, isn't it?
