Plsql_optimize_level parameter

Dear all,
11.2 on linux.
We need to disable this parameter as it is deprecated. the db was using a spfile, I created pfile out of this spfile and removed this parameter from the initfile.
but, when I startup with this pfile, it is still showing the parameter value as 2.
How to proceed ?

Thanks Amn, but I started the db using pfile
{code{
SQL> startup pfile=initVIS.ora

Plsql_optimize_level parameter resets itself

when I log in to the system and run the following code
select * from v$version;
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production

alter system set plsql_optimize_level = 2;
alter system set succeeded.
select value from V$parameter where name = 'plsql_optimize_level';
2Then I disconnect and connect to the db again and run the following query
select value from V$parameter where name = 'plsql_optimize_level';
0It is set to 0, how? I mean, why it s reset itself? I don't understand.
Thanks for your help

Then you might want to cross-post in the sql developer forum.

Post the full sql developer version you are using and provide links to your two threads in this forum.
There could be a bug in sql developer that the team needs to be aware of and the Oracle developers monitor that forum.

Again I failed at an Interview.....

Hi Frens,
I could not make thru this time also. Below are the few questions, I was asked :
1. You have an RMAN backup scheduled [10g, archivelog mode]. Accidently, system.dbf file was dropped. How would you recover the database.
2. Again 10g, RMAN, what is the single line command to backup all datafiles, control file and spfile.
3. Have you done any upgrade/migrate : explain the procedure to upgrade from 9iR2 to 10g R2.
4. How do you find out the unused indexes in the database.
5. How do u tune? R u tuning database or SQL. If SQL how do u tune SQL.
6. How do u find out why a SQL is not using the index created.
7. What does PLSQL_OPTIMIZE_LEVEL parameter imply?
8. Whats the importance of CURSOR_SHARING parameter?
My Answers :
1. I was confused
2. Cant remember exact syntax but somehow made it.
3. I replied I had done upgrades but never expereinced a 9iR2 to 10gR2
4. I did this one few time before but cant answer.
5. Answered comfortably
6. Answered
7. Dont know
8. Know it is important but not aware of its exact importance.
Thanks,

Think of it as a learning experience instead of a failure and you'll build more confidence for next time. Going to interviews are always a learning experience whether technical or not. You don't get knowledge (especially DBA) overnight, you need to learn it, practice it and experience it if you can. If you already have a base understanding of Oracle then that is good start, read and practice every day for a few hours, read CBO Fundamentals for eg and try to understand it, understand the concepts guide and architecture, read the forums, even the posts you think are irrelevant.
Also ask yourself, if you don't know some of the answers and find out that they're really important (RMAN say) then how will you deal with a real situation, what would you do if system.dbf was deleted? You can't be confused on the job in that situation otherwise you could just post "help, urgent!" on the forum and wait for someone to reply (which I've seen many times) :-\ Not the best position to put yourself in.

Using of cursor

Hi,
I need to declare a cursor that will need to go forward & backward how do i actually declare this type of cursor
and what are the keywords to go forward , backward or go to a specific row ?
appreciate ur advise
tks & rdgs

Hi,
Some of the info below is from this link --> http://www.dba-oracle.com/oracle_news/2006_03_17_test_10g_logical_io_plsql_faster.htm
This result may be due to the automatic bulking of fetches in PL/SQL, as noted by the plsql_optimize_level parameter. Steve Feuerstein notes the values for plsql_optimize_level below.
plsql_optimize_level:
· 2 Most aggressive, maximum possible code transformations, biggest impact on compile time. [default]
· 1 Smaller scale change, less impact on compile times
· 0 Pre-10g compilation without optimization
ALTER SESSION SET PLSQL_optimize_LEVEL = 0;
Setting plsql_optimize_level=2 (the default) will often replace cursor for loops (CFL) to the faster bulk collect. Feuerstein offers the following advice on this PL/SQL transformation with plsql_optimize_level:
===================================================
Ques :
1. Is the set plsql_optimize only for 10g ( i am currently using 9i)
2. where can i go to see this parameter if it also for 9i (i.e from which table/ dynamic view)
3. when it says choosing 2 will have the biggest impact on compile time , i presume it'll go faster ?

Deprecated parameter PLSQL_DEBUG

I am compliling a procedure using 11g. I get two warnings:
Warning(1): PLW-06013: deprecated parameter PLSQL_DEBUG forces PLSQL_OPTIMIZE_LEVEL <= 1
Warning(1): PLW-06015: parameter PLSQL_DEBUG is deprecated; use PLSQL_OPTIMIZE_LEVER = 1
What does this mean? Should I do as suggested or should I look for something wrong with my code?

I had a quick play with this but couldn't reproduce it in 11.2.0.1.
SQL> alter session set plsql_warnings='enable:all';
SQL> alter package testit compile plsql_debug=true;
SP2-0809: Package altered with compilation warnings
SQL> show errors package testit;
Errors for PACKAGE TESTIT:
LINE/COL   ERROR
0/0        PLW-06013: deprecated parameter PLSQL_DEBUG forces PLSQL_OPTIMIZE_LEVEL <= 1
0/0        PLW-06015: parameter PLSQL_DEBUG is deprecated; use PLSQL_OPTIMIZE_LEVEL = 1So far so good. But then the issue goes away when I recompile.
SQL> alter package testit compile;
Package altered.
SQL> show errors package testit;
No errors.I tried setting PLSQL_DBUG at the session level, but still no warnings:
SQL> alter session set plsql_ccflags = 'PLSQL_DEBUG:TRUE';
Session altered.
SQL> alter package testit compile;
Package altered.
SQL> show errors package testit;
No errors.Wondering what I'm missing - perhaps some session or package-level setting that retains the compilation parameter?
Anything odd in user_plsql_object_settings for the package?

Logical AND in MDX Reporting Services Parameter

Hi, I would like to implement logical AND on a cube parameter. I have seen examples of hard-coded logical AND in MDX.
(http://salvoz.com/blog/2013/12/24/mdx-implementing-logical-and-on-members-of-the-same-hierarchy/)
But I'm not sure how to apply this to a parameter's MDX dataset.
Here is an example of the automatically generated MDX which uses logical OR:
This is the drop down parameter:
WITH MEMBER [Measures].[ParameterCaption] AS [Department].[Department].CURRENTMEMBER.MEMBER_CAPTION MEMBER
[Measures].[ParameterValue] AS
[Department].[Department].CURRENTMEMBER.UNIQUENAME MEMBER [Measures].[ParameterLevel] AS
[Department].[Department].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue],
[Measures].[ParameterLevel]} ON COLUMNS
, [Department].[Department].ALLMEMBERS ON ROWS
FROM [MyCube]
And the demo report dataset is:
SELECT NON EMPTY { [Measures].[CompanyTbl Count] } ON COLUMNS,
NON EMPTY { ([Product Level No].[Product Level No].[Product Level No].ALLMEMBERS ) }
DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM
( SELECT ( STRTOSET(@DepartmentDepartment, CONSTRAINED) )
ON COLUMNS FROM [MyCube]) WHERE
( IIF( STRTOSET(@DepartmentDepartment, CONSTRAINED).Count = 1,
STRTOSET(@DepartmentDepartment, CONSTRAINED), [Department].[Department].currentmember ) )
CELL PROPERTIES VALUE,
BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING,
FONT_NAME, FONT_SIZE, FONT_FLAGS

Hi,
I can see there just one parameter @Department@Department in your script. But if you had two parameters that should return resultset affected by two parameters. You can do it as either select from subselect from subselect.
Example 1
SELECT
{x} ON COLUMNS,
{ROWS_SET} ON ROWS
FROM
(SELECT StrToSet(@Param1) ON COLUMNS FROM
(SELECT StrToSet(@Param2) ON COLUMNS FROM
[CUBE_NAME]
Or crossjoin between 2 parameters
SELECT
{x} ON COLUMNS,
{ROWS_SET} ON ROWS
FROM
(SELECT StrToSet(@Param1)*StrToSet(@Param2) ON COLUMNS FROM
[CUBE_NAME]

Report RFKLBU10: Missing Parameter for Logical filename in Release ERP 2005

Hello Experts,
Report RFKLBU10 in Sap Release 4.6c hat a parameter "Old dataset logical name".
The new version of this report in SAP Release ERP 2005 there is no such parameter.
Is this a SAP-Bug ?
Best regards,

There are no Export or Print events accessible for the viewer
Since it sounds like you are creating the reportdocument object in your click event, the settings on this object become out of scope on successive postbacks executed by other events.
to get around this without major changes, you can place your "report" object in session in this event and retrieve it from session on successive postbacks. This should solve your problems around navigation, printing and exporting. What you will need to do is check if the session object exists (usually in page_load or page_initialze) and if so, retrieve it from session and bind it to the viewer's reportsource. If the session object does not exist, then do nothing (ie you have not clicked your button yet that retrieves the parameter values from session and loads the report). Also, in your click event you can check if the report session object exists and if so, remove it so that it can be re-created with your new parameter values (ie i'm assuming the only time you want to set parameter values is in this event).

Unable to capture the parameter values from a PL/SQL procedure

Cannot assign an empty string to a parameter with JDBC type VARCHAR

I am seeing the aforementioned error in the logs. I am guessing its happening whenever I am starting an agent instance in PCo. Can somebody explain whats going on?

Replacing NULL and EmptyString('') with "Unknown" in SSRS parameter dropdown

All,
What I want to do is, in the SSRS parameter drop down, instead of showing NULL and Blank values(), i want to categorize them as "Unknown", so, if the user selects "Unknown" from the SSRS drop down parameter, he should be able to see all
the records that have NULL values or empty strings in that particular column in the result set.
Can you tell me, how should I handle it in my main stored proc as well as in the dataset?
Right now, i have something like this:
Where
(t1.name in (select value from dbo.Split(@TName,',')) OR @TName IN ('All'))
-- Where t1.Name has empty strings and NULL values. Both of these values should be categorized under "Unknown"
-- How would the dataset query look like? Right now I have this query for populating the drop down for that parameter:
Select All
UNION
Select Distinct Name
Order BY 1

Hello,
Please refer to the following stored procedure:
SELECT
CASE WHEN TName IS NULL OR TName = ''
THEN 'Unknown' ELSE TName END AS TName
From DemoTable
Then, use following query code to get the parameter values:
SELECT Distinct
CASE WHEN TName IS NULL OR TName = '' THEN 'Unknown'
ELSE TName END AS TName
FROM DemoTable

Host parameter null and convert SOAP to HTTPUrl

Hi,
We are trying to fire a SOAP request and print the response but its throwing this error
Exception in thread "main" java.lang.IllegalArgumentException: host parameter is null
The piece of code is:
HttpClient hc = new HttpClient();
System.out.println("Came here");
int iResultCode = hc.executeMethod(post);
executeMethod(post) is failing but when I print the value of post, its �org.apache.commons.httpclient.methods.PostMethod@fd54d6�
Can anybody throw some light on this error and how to solve it??
Also, there�s another issue.
We are upgrading from Weblogic 7.2 to 9.1
Earlier we were able to pass the request and get the response in HTTPUrl form but now after upgrading, its getting passed in SOAP format. Is there any way to bypass the SOAP and get it in HTTPUrl format or what are the configurations to be made to adapt to the SOAP format?
connection =(HttpURLConnection) url.openConnection();
This line was returning HTTPUrl format, now its coming in SOAP format

your PostMethod takes the Url as the parameter. Check you are using the proper URl i.e like http://host:port/name?params like that

SOURCE_PACKAGE is INCOMPATIBLE with the FORMAL PARAMETER DATA_PACKAGE

Hello Experts,
Infocube A is getting updated from shopping carts DSO. I have added 3 new fields in SC DSO then cube transformations got inactive. I do not want 3 new fields in cube. we have report on DSO. Below is syntax error when checking transformations.
Error: In PERFORM or CALL FUNCTION "ROUTINE_9998", the actual parameter "SOURCE_PACKAGE" is incompatible with the formal parameter "DATA_PACKAGE".
3 New fields are available in tys_SC_1 but not available in tys_SC_1_full. I tried to insert 3 fields in tys_SC_1_full but still it is showing same syntax error. And more TYPE is availalbe tys_TG_1_full. This type does not have 3 fields.
Please advice.
Thanks in advance.
Regards
Venkata.

Hello Rathy,
I have resolved issue by addinng fields to data package. Issue is becasue of 4 fields in source and I have added only 3 fields in data package. Added one more field to data package and no syntax errors when checked.
Thanks for the input and points assigned.

SSRS 2012: How to get a "Select All" that returns NULL instead of an actual list of all values from a multi-select parameter?

I have a multi-select parameter that can have a list of thousands of entries. In general, the user will pick a few entries from the list or "Select All". If they check "Select All", I would much prefer that I get a NULL or an empty string
instead of a list of all values. Is there any way to do that?
In experimenting with a work-around, I tried putting an "All" label with a null value in the list, but it is ignored (does not display in the drop-down). If I use an empty string for the value, my "All" entry does get displayed, but so
does "Select All", which is confusing. Is there a way to suppress "Select All"?
- Mark

I adapted the following from a workaround posted by JNeo on 4/16/2010 at 11:14 AM at
http://connect.microsoft.com/SQLServer/feedback/details/249227/multi-value-select-all-parameter-in-reporting-services
To get a null value instead of the full list of all values when "Select All" is chosen:
1) Add a multi-value parameter "MyParam" that lists the values to choose.
2) Add a DataSet "ParamCount" identical to the one used by "MyParam", except that it returns a single column named [Count] that is a COUNT(*) of the same data
3) Add a parameter "MyParamCount", set it to hidden and internal, then set the default value to 'Get values from a query', choosing "ParamCount" for the Dataset and the one [Count] column for the Value field.
4) Change the parameter for the main report DataSet so that instead of using [@MyParam], it uses this expression:
=IIF(Parameters!MyParam.Count =
Parameters!ParamCount.Value, Nothing, Join(Parameters!MyParam.Value, ","))

In this code i m facing memory problem.
It is not refreshing the memory every time.
So plz give me proper solution.
Its urgent.
Thanks
Ranveer

Hi,
   I suppose you are trying to store some particular value in memory in one program and then retieve it in another.
If so try using EXPORT data TO MEMORY ID 'ZC1'. and IMPORT data FROM MEMORY ID 'ZC1'.
To use SET PARAMETER/GET PARAMETER the specified parameter name should be in table TPARA. Which I don't think is there in your case.
Sample Code :
Data declarations for the function codes to be transferred
DATA : v_first TYPE syucomm,
       v_second TYPE syucomm.
CONSTANTS : c_memid TYPE char10 VALUE 'ZCCBPR1'.
Move the function codes to the program varaibles
v_first = gv_bdt_fcode.
v_second = sy-ucomm.
Export the function codes to Memory ID
EXPORT v_first
       v_second TO MEMORY ID c_memid.        "ZCCBPR1 --- Here you are sending the values to memory
Then retrieve it.
Retrieve the function codes from the Memory ID
IMPORT v_first TO v_fcode_1
         v_second TO v_fcode_2
FROM MEMORY ID c_memid.                                   "ZCCBPR1
FREE MEMORY ID c_memid.                                   "ZCCBPR1
After reading the values from memory ID free them your problem should be solved.
Thanks
