RE: Unix question
Hi, You can use the grep command in the following manner: grep -v try filename The option -v negates the search pattern, meaning rows which do not have a try string in them. The string can be enclosed in double quotes as well, this is useful if you are searching for multiple patterns... Hope this will help.

Performance Query - help
Hi all, I have a query which takes 4 seconds to execute. The query looks like: SELECT DISTINCT tfc_fct_value FROM PD_TMP_AGG_VALS_5071_544,PD_OUTPUT_ITEMS,tp_fact_ctl WHERE OUI_OUT_ID=5071 AND OUI_FACT_ID IS NOT NULL AND oui_item_type=tfc_item_type AND vd17=oui_fact_id ORDER BY tfc_fct_value Another query follows this : SELECT DISTINCT tfc_fct_value FROM PD_TMP_AGG_VALS_5071_544,PD_OUTPUT_ITEMS,tp_fact_ctl WHERE OUI_OUT_ID=5071 AND OUI_FACT_ID IS NOT NULL AND oui_item_type=tfc_item_type AND vd18=oui_fact_id ORDER BY tfc_fct_value Each of these queries take approximately 4 seconds to execute. As you can see above, the two queries differ in the vd columns. I need to execute the same queries atleast twice for various conditions. The queries return 4 rows. Initially I was creating a temporary table to hold the result set and then query the table. Later it was decided that there could be few more queries with differing vd, taking values like VD19, VD20 etc.. Now, my question is will it be alright if i create say 5 temporary tables for each of the distinct VD values or execute the query without creating tables. Suppose i have 5 vd values viz VD17, VD18, VD19, VD20 & VD21... If i am not creating temporary tables, and i am running the same queries twice ( this is for some other condition ), it would take around 2* 4* 5 = 40 seconds... Whereas if i create tables and then query through them, it would take around 22 seconds.. This is because once the table is created for the first time,, then querying it is faster.. Now can anyone please tell me if creating temporary tables is fine or is there any method to cache the query or some other way... Please put forward your comments and suggestions.

Query on Dual
Hi all, Can anyone tell me the performance issues related to the excessive usage of the DUAL table in pl/sql procedures? I remember reading an article about this ( I dont remember if it was in ASKTOM site ) wherein it was told that excessive usage of DUAL comes with a cost and there was a suggestion in that to create a view on the system table X$DUAL.. If anybody has a link to that please send it to me. Thanks to one and all.

RE: procedure/function error
Hi
purushotam,
since
it is a function that you are creating , its return value needs to be
collected.
hence
after BEGIN clause give a statement like
v_ret:=EMP_SEL('gali'); where v_ret
is a local variable of type varchar2
This will work.
Regards
Kesh

RE: RE: Schedule Analyze using DBMS_STATS ???
Hi all,
Everyone is recommending DBMS_STATS to be used for computing the
statistics.
But even after specifying the parallel option , DBMS_STATS is taking lots of time !
in comparison to Analyze...
In case of tables with a million records the query just hangs when i use the stats
package...
Can anybody tell me whts happening ?

Sorry JP, I should have clarified that DBMS_STATS is the way to go, when on
a 9i or above release. One of the simple factors being that ANALYZE is being
deprecated.. There seemed to be a number of bugs/quirks, whatever you want
to call them, in certain 8.1.x versions, which are now fixed within 9i..
There's a number of threads about the issues, available in the list archives
(you can find them at http://www.faqchest.com), which I dug around - as I
remembered seeing a post by Connor McDonald, where he gave away an alternate
script to gather stats, here's the mail:
http://www.faqchest.com/prgm/oracle-l/ora-02/ora-0210/ora-021011/ora02100802
_06150.html
I think the general consensus is that DBMS_STATS is quicker. I've never
personally done any comparative benchmarks to corroborate this sheep
following attitude though.. ;)

Mark

Thanx a lot Mark.
Sure , your code has given me a starting point.
let me change accordingly to use DBMS_STATSe and give a try :-)
So,can i conclude that DBMS_STATS is better than ANALYZE ?!
Someone over the list mentioned that DBMS_STATS is slower.
is it so ? What is your opinion regarding this ?!
just curious to know !
Regards,
Jp.

RE: Need help
Yes, I am talkin about the time it takes. The analyze command takes around 2 mins to esimate statistics of a table with a Million records whereas the dbms_stats package function is merely hanging !! And besides, Djordje is telling that they nearly take up the same time !! But i am not experiencing anything like that.. Do i have to change any settings to make it run faster ?? -Original Message- Sent: Monday, June 02, 2003 9:40 PM To: Multiple recipients of list ORACLE-L Kesh - What do you define as performance? 1. How fast a table is analyzed? 2. The performance of the queries that use the statistics that were collected? What Oracle version are you on? In theory, you can analyze tables when the system load isn't so great. In 9i you can even have Oracle decide when a table needs re-analyzed so it really lowers the system requirements.
