Explain plan cannot get information

Ｉ try to run explain plan to tunning my sql. After I run explain plan, the result did't show any Statistics.
Who Can I get these Statistics? Should I install any pacakges or set any configs?

Hi..
The INVALID status could be the reason of the your problem.You still haven't said what ORACLE version you are using.
Run UTLRP -- This script recompiles all PL/SQL modules that may be in an INVALID state, including packages, procedures, types, and so on.
SQL> @?\rdbms\admin\utlrp
And then check back the status of the packages by using the same query.Then, run
exec dbms_stats.gather_table_stats(ownname =>'ONWER','tabname => 'CUSTOMERINFO', cascade => true, estimate_percent =>DBMS_STATS.AUTO_SAMPLE_SIZE, degree => n);
try to first gather the table's statistics, then go for the system stats.

I was wondering if you ever figured this out. I have the same issue. When I try to use the support communities, there are so many with the same problems and never seem to be any replys?? Not very helpful and I can not get Apple to return my emails.

*/To bypass the problem (probably), and to see how it happened (possibly) see http://jonathanlewis.wordpress.com/2010/01/25/old-plan_table/
Not sure why you keep getting the same plan, but dbms_xplan does a 'select where plan_id = (select max(plan_id) ..) so perhaps the plan_table(s) you keep using have an artificially high plan_id which is always getting selected. (You could try doing: delete from plan_table ; commit; )

Explain Plan Table

Hi,
I have created the plan_table using utlxplan.sql but still i am getting the error:
ORA-02404: specified plan table not found
Is there something else to be done to get it fixed?
please suggest.
Regards
Arpit

As Lukasz suggested check the table privs between the schema where the table was created and the user trying to use it. Also make sure there's a synonym for the user using explain plan to get to the plan table easily; a public synonym might work best

Not able to execute the explain plan in development.

Hi In TOAD when try to click "Explain plan current statement." icon, I getting the below error message. ORA-00604: error occurred at recursive SQL level 1 ORA-01950: no privileges on table space 'DEFAULT_DATA' can anybody give some idea to solve this issue?

Is this a new user? You could be running out of quota.
Ask your DBA to user on that tablespace.
Alter user <username> quota unlimited on DEFAULT_DATA;
OR
Title
When I do an Explain Plan, I get the error: ORA-00604: error occurred at recursive SQL level 1 OR
Description I get the error below when I run / execute an Explain Plan.ORA-00604: error occurred at recursive SQL level 1 ORA-01536: space quota exceeded for tablespace ‘USERS’ (not same but similar)
Resolution Ensure the Plan Table your Toad is using exists, valid, and can use enough space in the tablespace or give unlimited tablespace rights. Setting Toad to use the PLAN_TABLE from SYS schema via View menu | Toad Options | Oracle | General | Explain Plan can resolve the issue as well.

Wich rules are based the explain plan

Hi!
Please some one can tell me, which are the specific ranges to say one data base function is acceptable?
I mean, i know with the explain plan, can get the values of a transaction, but i need to know which ranges are considered good or besides when the range are over value
If i can't get values, i need to know the limits or general rules, to specify if transaction or procedure is acceptable or no.

If, by "ranges", you mean "execution" time then the answer to your question
is "It depends" !
It is user requirements that specify acceptable response time for things like
a. Data Entry and Validation in a Form
b. Query in a Form
c. Running a Report
For a., user acceptance might be a few seconds only.
For b., acceptability might be anywhere from 10seconds to a minute, depending on the nature of the query.
For c., acceptability might be a few minutes to a day (24hours), depending on
the nature of the report.
As the designer, developer and dba, your responsibility would to to ensure
that all the database operations required to be executed are completed
within the acceptable time.
Type a might consist of 3 queries and 1 insert.
Type b might consist of 1 or 2 queries (or variable queries !)
Type c might consist of 2 to 200 queries, some DML, temporary tables.

I cannot get GPS Only to work on my ipad3 (4g version, but not on an active cell plan, and wifi off). Is there some new requirement in 7.1 or 7.1.1 to have cell and/or wifi enabled for GPS to work? I am testing with MotionX

It seems like I cannot get GPS only to work on my ipad3 (4g version, but not on an active cell plan, and wifi off). Is there some new requirement in 7.1 or 7.1.1 to have cell and/or wifi enabled for GPS to work? I am testing with MotionX, garmin blueChart mobile, and a GPS monitoring tool. All show no signal. If I turn on cell and wifi, it says I get gps signal, but can't tell if that is from the GPS chip, or just from cell and wifi only (maybe with some gps mixed in)? Any ideas on how to get iPad working with GPS only??

Roger that. Thanks for your time.

Cpu time is not getting displayed in explain plan

2)@$ORACLE_HOME/rdbms/admin/utlxpls.sql
But i am getting only following columns in result .

How can i extimate CPU time ?
Pls help
Thanks

How can i extimate CPU time ?You need to mention your database version (4-digits, e.g. 9.2.0.8).
In Oracle 9i CPU costing is disabled by default, you need to gather WORKLOAD system statistics to enable the CPU costing.
In 10g CPU costing is enabled by default and uses default NOWORKLOAD system statistics if no WORKLOAD system statistics have been gathered. It can only be disabled by setting an undocumented parameter or by changing the OPTIMIZER_FEATURES_ENABLE parameter back to 9i compatibility.
You can check the status of your system statistics by running the following query in SQL*Plus:
column sname format a20
column pname format a20
column pval2 format a20
select
sname
, pname
, pval1
, pval2
from
sys.aux_stats$;Can you show us the actual (complete) output you get from "utlxpls.sql"? Use the \ tag to preserve formatting here:
\output
\will show asoutput

iTunes as you see it in the application window uses a series of files and folders contained in the iTunes folder. Some people make the mistake of only backing up their media in which case all you have is a bunch of media files without the iTunes structure. In that case you have to build a new library yourself.
What exactly do you mean "not recognized"? The phone does not show up on the computer at all, or it does but it says it will wipe the phone? The wipe the phone stuff is again because it cannot find the original library to which it was synced. You need to transfer the entire iTunes folder from the old computer or the backup you made of it.
What are the iTunes library files? - http://support.apple.com/kb/HT1660

Hello Jeff,
Thanks very much for your reply. I looked over the article you mentioned, but I have tried all of these methods, but only get the response "The item “29394D00” can’t be moved to the Trash because it can’t be deleted." Similarly, I cannot Get Info on the file. This is why I'm so concerned, it just appeared on my desktop, but I cannot touch it, or open it or delete it...
If you have any more tricks up your sleeve, I'd love to hear about them...
