How to find total refresh time of Materialize view?

Hello All,
I want to know the total refresh time of Materialize view. i m refreshing MV by below statement
i hv not logging the start and end time of this in process.
exec dbms_mview.refresh('EMP_MV','C','',FALSE,FALSE,0,0,0,TRUE);
So, anybody can you please know the using which database table it cab be possible?
Thanks in advance

The only way you can log the refresh time for each execution is to wrap the call inside a procedure that also logs the start and end times to a logging table.
(if you manually run the exec dbms_mview.refresh from an SQLPlus command line, you could also SET TIMING ON in SQLPlus)

How to find total no of record in cube

Hi Experts,
How to find total no of records in a cube.
Thanks in Advance.

Hi
If you want total number of records in a CUBE then you have to check in both F Table and E table.
Go to LISTSCHEMA tcode in your system, give your CUBE name and execute.
You will fine two table E and F table
goto SE16 -->give the table name and click on number of entries.You will get number of records.
Check the below thread

How to find total recs in a local table for a particular condition

Hi,
How to find total recs in a local table for a particular condition?
Thanks,
CD

Well, you may want to try this as well, and compare to the LOOP way. Not sure what kind of overhead you may get doing this way. Here ITAB is our main internal table, and ITAB_TMP is a copy of it. Again I think there may be some overhead in doing the copy. Next, delete out all records which are the reverse of your condition. Then whatever is left is the rows that you want to count. Then simply do a LINES operator on the internal table, passing the number of lines to LV_COUNT.
data: itab type table of ttab.
data: itab_tmp type table of ttab.
itab_tmp[] = itab[].
delete table itab_tmp where fld1 <> 'A'.
lv_count = lines( itab_tmp ).

How to find the Names of Most costly Views or Most Time consuming views

Hi All,
I had a database consisting of almost 200 views,as a part of Optimization process i want to find out the most costlier views.How to do that.Actually i want the names of the VIEWS,so that i can optimize that.Can any one help me out?
I had one more doubt in our Database a view is created like view A( which is created by joining several tables).so do i need to add index on this view separately or does it take the index of the tables which i joined? And in our Database i had created
a VIEW which is derived from other views(the Joining objects are views not tables),so while i select recoreds from this views which is derived from other views it is taking a lot of time.Is tehre any problem with that?

How to find total memory for Oralce Memory utilization

Hi,
How to find total amount of memory utilized by oracle including SGA+PGA+PROCESS
Thanks,
Abk

Is you OS 32-bit ? If you add /3gb in boot.ini , then it will limit oracle.exe to go only upto 3gb.
Add /PAE in the boot.ini and remove /3gb.
then use db_block_buffers parameter instead of db_cache_size
for using db_block_buffers, you need to set another parameter also.
use_indirect_data_buffers=true
db_block_buffers=<number of blocks
db_block_buffers=db_cache_size in kilobytes /db_block_size
(since db_block_size is 8 kllobytes by default in Windows..

How to find out the time when the ASE started?

Normally, ASE not reboot for production. Only for maintenance or performance tuning, maybe need to reboot ASE.
Question is how to find out the time when ASE was started?
one way maybe is check errorlog. Any more simple way no need to login to server OS?

Hi Kent,
In ASE 12.5 and up, you can do 'select @@boottime' For older releases, a general method is 'select crdate from sysdatabases where dbid=2'
1> select @@boottime, crdate from sysdatabases where dbid=2
2> go
crdate

How to find total number of records in a BDoc?

Dear all,
I have replicated about BP 1088 records from ISU into CRM system with block size 100. Technically on SMW01, for each successfully processed BDoc, there will be 100 records (corresponds to 100 block size). But due to some failed BDocs, not all "successfully" BDocs will have 100 records each, some may have only 1 record inside...or 30...or 88 for example. So, may i know how to find or is there a report i can look into to find the total number of records clearly shown for each of the successfully processed green status BDocs???
Please help and points will be rewards!!
Thank You
Best Regards,
CK

I am just showing this to show how to get the rowcount along with the cursor, if the program has so much gap of between verifying the count(*) and opening the cursor.
Justin actually covered this, he said, oracle has to spend some resources to build this functionality. As it is not most often required, it does not makes much sence to see it as a built-in feature. However, if we must see the rowcount when we open the cursor, here is a way, but it is little bit expensive.
