PL/SQL :: Execution Time Spread Across Various Procedures Within A Package
Jul 6, 2012
I have huge package having numerous procedures. Therein there is one wrapper procedure which is invoked from front end and which in turn calls other stored procedures within the package. The stored procedures called return the result to the wrapper procedure which in turn calls other stored procedures.
The ultimate result is returned to the calling environment by the wrapper procedure itself.I need to know the time taken in totality by the wrapper procedure along with the individual execution time of each procedure called by the wrapper procedure. I am not allowed to modify the code for adding timestamp capturing though.
I could execute a package for eg if i had a package with procedures related to statistics and i run them each night, could i just do an exec on the package and it would run all those procedures??
Its not possible but i could call each procedure from ONE procedure
By referring through net I have written the following PCK file. I have installed my Oracle 11g database in VirtualBox(Win XP). I can able to select the tables using query from the host(Windows 7)
CREATE OR REPLACE PACKAGE APEX_SYS_PCK AS TYPE refcursortype IS REF cursor PROCEDURE GET_USER_DETAILS( D1 OUT refcursortype, P_USER IN VARCHAR2, P_PASS IN VARCHAR2);END APEX_SYS_PCK; / CREATE OR REPLACE PACKAGE BODY APEX_SYS_PCKAS PROCEDURE GET_USER_DETAILS( D1 OUT refcursortype, P_USER IN VARCHAR2, P_PASS IN VARCHAR2) IS BEGIN OPEN D1 FOR SELECT * FROM APEX.PERSONS; END GET_USER_DETAILS; END APEX_SYS_PCK;/
When I try to run the script I am getting the following error. How to solve this problem?
Project: sqldev.temp:/IdeConnections%23vAPEX.jprF:PACKAGESAPEX_SYS_PCK.sqlError: PL/SQL: Compilation unit analysis terminatedError(1,14): PLS-00905: object APEX.APEX_SYS_PCK is invalidError(1,14): PLS-00304: cannot compile body of 'APEX_SYS_PCK' without its specification
how many functions and Procedures are exist in Package. Is it possible to identify through query.
Eg: I have one Package:- ABC. This ABC package having 2 functions and 3 procedures. I want, total no.of functions and total no.of procedures through query.
1- I do not have access to TOAD for Oracle yet 2- I can connect to SQLPLUS: Release 9.2.0.1.0 3- We have many stored procedures in packages that are available from the TOAD for Oracle interface 4- I need to be able to see the specs/body of some packages containing some procedures. 5- I am connected to the appropriate DataBase1 (for example), but from here what to do from SQLPLUS command prompt ?
For example: SchemaName1.PackageName1.ProcedureName1
In our production environment some SP's are executing longer duration, but when same SP is executed from PLSQL Developer client it is executing vary quickly.
Is there a way to know how much time will a query take to execute without running it, just like using the autotrace (traceonly) and explain plan utility.
I am facing a very strange issue with one of our Oracle query. The query is usually completes in a minute or two. Even the execution plan of the query is good and it works perfect most of the times, as expected. The query fetches about 1000-2000 records each day.
But on a given day, the query takes about 30-40 mins to execute completely. Upon checking the load on DB server, there are no other processes running which can impact the run time of this query. Moreover, the record counts fetched are almost same as compared to other days. There is no pattern observed as that this phenomenon occurs. it all happens once in a while.
Configuration is Oracle 10g with RAC environment on LINUX
How can i check the avg time taken by an execution plan. Actually i have a very big query and it changes its execution plan very often, we would like to lock the best execution plan and to find it , i would like to know the Average Execution Time the query takes when it runs using different different execution plans.
- First time to execute: Using all indexes on 2 tables
- Second time to execute: Using only indexes on first table, full table scan on the other
- Third time to execute: Do FTS on both of tables.
Now, I show the objects and relate information here:
The Tables:
system@dbwap> select count(*) from my_wap.news_relation;
COUNT(*) ---------- 272708
system@dbwap> select count(*) from my_wap.news_content;
COUNT(*) ---------- 95092
system@dbwap> desc my_wap.news_content; Name Null? Type ----------------------------------------------------- -------- ---------------- ID NOT NULL NUMBER(11) SUBJECT NOT NULL VARCHAR2(500) TITLE VARCHAR2(4000) STATE NUMBER(1) IMGPATH VARCHAR2(500) ALIGN VARCHAR2(10)
In my code I am using delete statement which is taking too much time to execute.
Statement is as follow:
DELETE FROM TRADE_ORDER_EMP_ALLOCATION T WHERE (ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT) IN (SELECT ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT FROM LOAD_TRADE_ORDER WHERE IND_IS_BAD_RECORD='N');
Every column in "IN" clause and select clause is containing index on it
Every time no of rows which to be deleted is vary (May be in hundred ,thousand or hundred thousand )so that I am Unable to use "BITMAP" index on the table "LOAD_TRADE_ORDER" column "IND_IS_BAD_RECORD" though it is containing distinct record in it.
Even table "TRADE_ORDER_EMP_ALLOCATION" is containing "RANGE" PARTITION over it on the column "ARTEMIS_SOURCE_SYSTEM_ID". With this I am enclosing table scripts with Indexes and Partitions over it.
way for fast execution in of above delete statement?
Is there any oracle dictionary view which captures the queries being run by users on the database and time taken to execute those queries?We need to find out the OS user not the database user since we have to identify the users who are executing long running queries.We require this basically to monitor the long running queries on the database.
I'm planning to decrease the time taken to execute data by managing the redo log file but I'm kinda stuck in some aspect : > Why is my OPTIMAL_LOGFILE_SIZE is showing NULL ? > I'm trying to resize the LOGFILE capacity from 100M to 200M and I'm also adding 1 more LOG GROUP with 200M capacity too but turned out that didn't decrease my execution time.
Elapsed times include waiting on following events:
Event waited on Times Max. Wait Total Waited ---------------------------------------- Waited ---------- ------------ SQL*Net message to client 1 0.00 0.00 db file sequential read 85704 0.31 460.55 latch free 1 0.00 0.00 SQL*Net message from client 1 14.98 14.98
[code]...
Why the elasped time changed when data and plan hasn't changed at all? Also why the plan has different stats for round 1 and 2 on db1 and db2?
I ran it 2 times each round each database so hard parsing shall not be issue.Also why the number of rows accessed are different in db1,db2 and db3,db4 especially for step1 when count of crt.qtn_cun_id is similar?
In fact when the query was taking long I was the only user on the system Also I used hard coded value (no bind variables at all)
I checked num_rows, distinct keys as well which are quite similar across all 4 databases Also no stats where gather during the query execution
Any example of how to load data into an oracle spread table OCX control
I have successfully inserted the the oracle spread control in a form and also created the program units form the control but unable to load data into the it at run time.
I am try to import 4G dump in Oracle 11R2 version, in that we have around 9000+ Package Body which is taking huge time than other objects (about 8 to 12 hrs) and also it is expecting lots of system space (roughly about 10GB).
I have tried both parallel and non-parallel.how to improve speed of the package body import.
Details about the Schema & Import No. of objects in Schema
SQL> select object_type,count(1) from user_objects GROUP BY ROLLUP( object_type);

I need to find out in DB Package where this Package is installed (in which schema). The problem is this DB Package can be installed in various schemas. This means that I can't use select user from dual or system environment SYS_CONTEXT('USERENV', 'OS_USER').
I have a package with several procedures which raise and catch an error if a foreign key constraint has been violated. I put the the following code in my package body:
Now all the procedures inside the package which catch this exception in the EXCEPTION block work fine. I would like to be able to use that exception outside of my package as well though, how would I do this?
whats the best way to modify a table via a procedure for example if i have a table with records: id, fn, ln, address, tel, dob
how would i go about creating a procedure that modifies a record. The problem is what param needs to go in? i could certainly have different procedures that modify different things like one for modifying tel, one for modifying address, but is there a way to combine it all into ONE procedure so that if user wanted he could put in exec modifyTable(2, 099898787) to modify tel and then modifyTable(2, 'a new address') to modify address... ?
we are doing a performance tuning on a large database. Our main aim is to capture all the packages/procedures/view that are running on database. Below given is the format we have prepared
Eg: SPIdSP_Name CPU TimeI/OLine Executed 1Emp_AllDetails221 1Emp_AllDetails582 1Emp_AllDetails25103
[code]...
Requirement:Write an Procedure that captures the above given information in the background of database and stores the information in a table.write the procedure to capture the above given information.
