DBMS_PROFILER Empty
Hi,
I'm having some problems with DBMS_PROFILER. I have a good sized PL/SQL package, approximately 2000 lines, that I am trying to profile. I do a DBMS_PROFILER.START_PROFILER at the beginning of the whole process and a DBMS_PROFILER.STOP_PROFILER at the end. Then I user the profiler.sql script to generate the formatted HTML page of the run. I've done this countless times and have had a good experience. Sometimes however the results would be a little off...
Sometimes I'd run it and get an HTML with no source listing even though I had explicitly re-compiled the package (normally with debugging because I've found DBMS_PROFILER works better with it on). Sometimes I'd get the source listing, but none of the times or execution counts where there. Instead they were all zeroes. I've looked in the source tables and see the _DATA table does contain the zeroes so the profiler.sql script seems to be working fine. Other times it would normally and give me good results.
Now, recently, no matter what I try, I cannot get a good run of data. I've looked online and the only "instructions" I see for DBMS_PROFILER are to create the tables/ sequences and then add the calls to your PL/SQL, the little bit about compiling in debug is something I found myself, so I'm really lost as what to try. I think when I first started working with DBMS_PROFILER there were some grants that had to be done, but if those weren't in place it wouldn't even run.
I did drop and recreate the tables/ sequences and that did not help.
Does anyone have anything else I might try? I should mention I'm on Oracle 11g. Here is the exact version from sqlplus when I log in. I'm not sure what version of DBMS_PROFILER I have if it really even has one.
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
Thanks,

Well sorry about resurrecting the old post, but I figured out what the issue is. In the profiler.sql script that generates a fancy HTML report from the DBMS_PROFILER tables there is a DEF statement like the following.
DEF p_top = 10;
This is defining how many longest running lines to show in the summary at the beginning of the report. Later in the script there is a line that looks like this.
:v_top := TO_NUMBER('&&p_top');
This is assigning the value from p_top to v_top, but for some reason getting the value isn't making it over correctly. I think v_top is just getting a NULL. Worst of all it's inconsistent. Sometimes it seems to work and sometimes it doesn't.
The quick and dirty fix I came up with was to just hard code the value for v_top. For good measure I commented out the first DEF line I mentioned as well.
:v_top := 10;
There is a preliminary update this script does to plsql_profiler_units and plsql_profiler_data to the spare1 and spare2 columns which flags the top longest running lines with a rank. If this update fails to mark any lines, because of a missing value for v_top, then the rest of the script fails to correctly generate the report. I'm not sure why this DEF statement is giving me so much trouble, but I'd be curious if someone had an answer.
There is also an auxiliary fix, which I actually found first, where if you go to the c1_units cursor at the bottom of the script and comment out the requirement that spare1 IS NOT NULL in the SQL you can get the source to print out with the counts and timings, but that doesn't fix the issue with the top 10 table.
CURSOR c1_units IS
SELECT unit_number,
unit_owner,
unit_name,
unit_type,
spare1,
spare2
FROM plsql_profiler_units
WHERE runid = :v_runid
--AND spare1 IS NOT NULL
ORDER BY
unit_number;
Thanks,
Kevin

Hi,
I ran the following code to profile my code:
<h6>
DECLARE
l_result BINARY_INTEGER;
retcode number;
errbuf varchar2(500);

l_result := DBMS_PROFILER.start_profiler(run_comment => 'xxotc_cust_class_stage_t: ' || SYSDATE);
my_pkg.main ( errbuf

,'small_file.txt'
l_result := DBMS_PROFILER.stop_profiler;

After the program completes, when I query the profiler tables plsql_profiler_runs and plsql_profiler_units I do not find any data.
Is there anything wrong that I am doing?

Oracle, Null and empty Strings
Currently I'm facing problems with a class, which contains a String, which
is set to "" (empty String).
When the class is persistent, oracle writes null to the table column
(which seems to be common oracle behaviour) and when retrieving the class,
the field is set to null as well, giving me a lot of null-pointer
exceptions.
Anyway ... I can cope with that (just a lot of extra work)
far worse is the problem, wenn searching objects, that have this field set
to "" oder null.
Oracle can't find the records because JDO creates Querys "where
string=null" or "where string=''" , where oracle expects "where string is
null" to find the records.
Is there a workaround or solution ?Yeah, that would work as well, thx, but since I have to cope with
null-Strings now everywhere in my program, it doesn't hurt just to forbid
empty strings on the program side.
In future times I'll test on Oracle first, then porting to DB/2 - this way
I suppose work is far less to garant compability.
Nevertheless ... having to set the bankcode into quotes is a kodo bug in
my opinion.
Kodo knows the type of classfields (in this case string) and shouldn't
send the parameter as a BigDecimal to the database.
Given that, and having only bankcodes of null (only neccesary when using
Oracle), the method would look like:
public Collection getAccounts (String bankCode)
throws Exception
return getAccounts (Account.class, "bankcode=="+bankcode);
which is how a transparent persistent layer, um, should be , um , I mean
... just transparent ;-D

Couldn't you just do something like:
public Collection getAccounts (String bankCode)
throws Exception
String filter;
if (bankCode == null || bankCode.length () == 0)
filter = "(bankCode == null || bankCode == "")";
else
filter = "bankCode == "" + bankCode + """;
return getAccounts (Account.class, filter);
If I understand the problem correctly, this should work for all the
databases.

What operations are you performing to cause this SQL to be issued? You
say you are having trouble removing objects, but this is clearly not a
DELETE statement. Is this the SQL that is issued when looking up
objects by identity?I'm not removing objects, I was removing just quotes from parameters ;-)
A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
First we have a class, representing a bank account:
public class Account {
private AccountMgr myAccountMgr;
private String bankCode;
private String id;
Note, that in nearly all cases bankCode will be a number or null.
I have a second class "AccountMgr", which does all of the persistant stuff
(seaching, making persistent etc.)
This class has two methods, one versatile (protected) to retrieve accounts
by a given filterString and one who just returns accounts by bankCode,
building the expected filterstring. Here is my current working version:
public class AccountMgr {
public Collection getAccounts(String bankCode) throws Exception {
if (bankCode!=null) {
if (bankCode.equals("")) {
throw new Exception("check code, bankCode='' not allowed to get
same behavior from DB2 and Oracle");
// if set, quote the bankCode
bankCode="""+bankCode+""";
return getAccounts(Account.class,"bankCode=="+bankCode);
protected Collection getAccounts(Class accountClass, String filterAdd)
throws Exception {
PersistenceManager pm = MyHelper.getPersistenceManager();
String filter="";
if (filterAdd!=null && !filterAdd.trim().equals("")) {
filter+=filterAdd + " && ";
filter += "myAccountMgr==_accMgr";
Query query = pm.newQuery(accountClass, filter);
query.declareParameters("AccountMgr _accMgr");
return (Collection) query.execute(this);
As you can see, in the first method I have to set the bankCode into
quotes, when it's not null.
This is because otherwise a filter like "bankCode=1234" will be translated
in a way, where 1234 is send as a BigDecimal to the database:
[...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

Hi There,
As far as I know, Null is not the same as an empty string; however, when I try this out, I get some unexpected results (well, at least unexpected for my liking):
SQL> CREATE TABLE TS (MID NUMBER,
2 MDESC VARCHAR2(20) DEFAULT '' NOT NULL);
Table created.
SQL> INSERT INTO TS VALUES(1,'');
INSERT INTO TS VALUES(1,'')
ERROR at line 1:
ORA-01400: cannot insert NULL into ("TT"."TS"."MDESC")So, according to the above scenario, I can't insert an empty string!! However, an empty string is a valid string that doesn't have tuples/data!!
How come Oracle translates the null string '' as NULL?

Null and empty string not being the same in object?
Hello,
I know that null and empty string are interpreted the same in oracle.
However I discovered the strange behaviour concerning user defined objects:
create or replace
TYPE object AS OBJECT (
value VARCHAR2(2000)
declare
xml xmltype;
obj object;
begin
obj := object('abcd');
xml := xmltype(obj);
dbms_output.put_line(xml.getStringVal());
obj.value := '';
xml := xmltype(obj);
dbms_output.put_line(xml.getStringVal());
obj.value := null;
xml := xmltype(obj);
dbms_output.put_line(xml.getStringVal());
end;
When creating xml from object, all not-null fields are transformed into xml tag.
I supposed that obj.value being either '' or null will lead to the same result.
However this is output from Oracle 9i:
<OBJECT_ID><VALUE>abcd</VALUE></OBJECT_ID>
<OBJECT_ID><VALUE></VALUE></OBJECT_ID>
<OBJECT_ID/>
Oracle 10g behaves as expected:
<OBJECT><VALUE>abcd</VALUE></OBJECT>
<OBJECT/>
<OBJECT/>
However Oracle 9i behaviour leads me to the conclusion that oracle
must somehow distinguish between empty string and null in user defined objects...
Can someone clarify this behaviour?
Thus is it possible to test if object's field is empty or null?However Oracle 9i behaviour leads me to the conclusion that oracle

Can someone clarify this behaviour?
Thus is it possible to test if object's field is empty or null?A lot of "fixes" were done, relating to XML in 10g and the XML functionality of 9i was known to be buggy.
I think you can safely assume that null and empty strings are treated the same by Oracle regardless. If you're using anything less than 10g, it's not supported any more anyway, so upgrade. Don't rely on any assumptions that may appear due to bugs. -
Difference in Null and Empty String
Hi,
I have been wondering about the difference between Null and Empty String in Java. So I wrote a small program like this:
public class CompareEmptyAndNullString {
public static void main(String args[]) {
String sNull = null;
String sEmpty = "";
try {
if (sNull.equalsIgnoreCase(sEmpty)) {
System.out.println("Null and Empty Strings are Equal");
} else {
System.out.println("Null and Empty Strings are Equal");
} catch (Exception e) {
e.printStackTrace();
This program throws Exception: java.lang.NullPointerException
at practice.programs.CompareEmptyAndNullString.main(CompareEmptyAndNullString.java:10)
Now if I change the IF Clause to if (sEmpty.equalsIgnoreCase(sNull)) then the Program outputs this: Null and Empty Strings are Equal
Can anyone explain why this would happen ?
Thanks in Advance !!JavaProwler wrote:
Saish,
Whether you do any of the following code, the JUnit Test always passes: I mean he NOT Sign doesnt make a difference ...
assert (! "".equals(null));
assert ("".equals(null));
You probably have assertions turned off. Note the the assert keyword has nothing to do with JUnit tests.
I think that older versions of JUnit, before assert was a language keyword (which started in 1.4 or 1.5), had a method called assert. Thus, if you have old-style JUnit tests, they might still compile, but the behavior is completely different from what it was in JUnit, and has nothing to do with JUnit at all.
If you turn assertions on (-ea flag in the JVM command line, I think), the second one will throw AssertionError. -
Check for null and empty - Arraylist
Hello all,
Can anyone tell me the best procedure to check for null and empty for an arraylist in a jsp using JSTL. I'm trying something like this;
<c:if test="${!empty sampleList}">
</c:if>
Help is greatly appreciated.
Thanks,
Greeshma...A null check might not be you best option. If your requirement is you must have both the date and time component supplied in order to populate EventDate, then I would use a Script Functoid that takes data and time as parameters.
In the C# method, first check if either is an empty string, if so return an empty string.
If not, TryParse the data, if successful, return a valid data string for EventDate. If not, error or return empty string, whichever satsifies the requirement. -
Interactive Report view is empty
Hi,
I'm on CRM 7.0 EHP3. I'm encountering empty report criteria and display when open the Campaign effectiveness and all other interactive report page. Please see the screen shot below. There is no error message on the screen, as well as ST22.
I've configured the interactive report and ran the configuration wizard /CRMBW/CONFIG_WIZARD successfully and no error found.
Also the roles SAP_CRM_OR_ADMIN, SAP_CRM_OR_CONFIG and SAP_CRM_OR_USER and SAP_ALL are given to the user in both clients.
Please let me know what could be the causes.
Thanks in advance.
cheers,
juliusOkay, problem seems solved. I don't know if it is a bug or a feature... (: Anyway, this view selects data from threads that had been created from a portal application. And if you create threads from WC_Collaboration server admin console, there's no data will be selected with FORUMCRAWLER_VW view. Sorry, have no time to check SQL query for those DB view, may be this behaviour is reasonable.

Can I somehow print an empty report, and specify with a parameter how many times it should be repeated?
The report is a form with checkboxes, and sometimes we want the empty one for someone to fill in when out on the field. And since this form is a subreport, we cant print the entire report over again, but need the subreport to be repeated, let's say five times.
/Thank you!Please re-post if this is still an issue or purchase a case and have a dedicated support engineer work with you directly

My photos on iphotos just became empty boxes, bordered by white intermittent lines. If I click on a photo it comes up, but I can't see what each photo is at a glance. Any ideas how to resolve this? thanks
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the options to rebuild the thumbnails.

Is there a way to prevent users from sending empty or incomplete PDF forms?
Hi all,
Using Acrobat Professional 8, I made a fillable form to individuals to fill in and submit to me as a pdf attachment to an e-mail or print out it and fill by hand.
Question 1. I want to make sure they don't send incomplete or empty forms back to me. Is there a way to do that?
2. The form is 8.5x15 inches. I want it to look like one continuous page on screen but print as 2 letter size pages. However, when i go to print it, acrobat scales it down to fit in one page which makes the text too small to read.
Please advise! Thanks.
KarenOn Question 2:
when you get to the Print menu in Acrobat/Reader look for scale to fit paper and uncheck if there is a reference to Full size check that.
