Inline plsql_optimize_level=3 and recompiling the sys schema??

Has anyone messed around with 11g’s new inline pragma?
I turned it on in a few packages which contains a lot of looping and it reduced the number subprocedure calls in the order of a few thousand. Because the db mainly servers web pages via mod_plsql, I found it to make pages just a tad snappier.
It seemed to work pretty well that I altered the system with plsql_optimize_level=3 and recompiled the entire schema.
This along with native compilation has made the website run the fastest I’ve ever seen it run. (I’ve already tuned sql statements and the sga size, so it was already running pretty fast.) Now it's just crazy quick.
I only wish that standalone functions would also get “inlined”. I have a few functions like “format_money()” which will not get inlined unless they moved inside of packages (or in the declaration of calling standalone procedure).
I’m wondering if anyone has set plsql_optimize_level=3 and recompiled the system schema? I recompiled sys.htp, sys.htf and sys.owa* packages just for fun. I didn’t do any metrics to gage the speed up. Just going off of feel, it does appear just a tad faster.
I'm considering recompiling the entie sys schema and wondering if anyone has done this or recommends it?

Hi Ravshan,
I thought a workaround would be to create a sql script like the following:
alter session set plsql_code_type=native;
alter session set plsql_optimize_level=3; then point to it in the setting for Tools|Preferences|Database|Filename for connection startup script. That doesn't work however, as the other preference setting for plsql_optimize_level overrides the session value of 3 during compilation from the UI.
According to Oracle documentation, level 3 was added for Oracle 11g. Prior to that, the same effect could be achieved by level 2 in conjunction with the INLINE pragma in the PL/SQL code.
You might want to make a feature request for this on the SQL Developer Exchange so the community can vote and comment.

And, of course, Compile for Debug does not work with the 'native' setting.

How to recompile the entire schema's INVALID objects in one go?

Hi,
How to recompile the entire schema's invalid database objects (such as package, function, procedure, trigger etc) in one go?
Please advise.
Thank you.

I often use this SQL.
select 'Alter ' || OBJECT_TYPE || ' ' || OBJECT_NAME || ' compile;' as DDL
from user_objects
where STATUS = 'INVALID';I sometimes use this SQL.

Hi
I am new to Oracle but not to VS. I have downloaded and installed the newest tools for Developer, having first tried the install for VS2003.net (which refused to install on my VS 2005.) I got the beta download and installed it, but my oracle explorer shows nothing. Any attempt to add a connection results in an error ORA-12560:TNS:protocol adaptor error. I had the full install of 10g r2 on my notebook, but removed it and opted for the XE version. I removed the Oracle_Home environment variable prior to installing XE. I am trying to connect to the HR database, and the account is unlocked. I saw a reference to the tnsfiles file, and that seems to be the problem, but I don't know what to do about it. Thanks in advance to anyone who can offer help.

Query on event based job in a client schema and not SYS schema

Hi, I am fairly new to oracle job scheduler and wanted your inputs on how to create a event based job that sends a mail based on success of another job.
I was able to implement this with the jobs being created under SYS schema. I did get email notifcation when errors were logged in exception table.
However, now the requirement has changed to create the jobs under a client specific schema.
The jobs got created successfully in CLIENT schema but the event based job is not working. It does not send the email notification.
I feel this is to do with not correctly subscribing to the event queue {sys.scheduler$_event_queue}.
Can CLIENT schema use the agent "AGENT" created under SYS to subscribe to the Scheduler event queue {sys.scheduler$_event_queue}? CLIENT is the schema in which the all jobs and procedures are created.
BEGIN
DBMS_AQADM.ENABLE_DB_ACCESS('AGENT', 'CLIENT');
END;
--Main Job that will load data and errors will be logged into exception table
BEGIN
dbms_scheduler.create_job( job_name=> 'CLIENT.LOAD_DATA',
job_type=>'PLSQL_BLOCK',
job_action=>'BEGIN CLIENT.p_loaddata;
END;',
start_date=>systimestamp,
repeat_interval=>'FREQ=MINUTELY;INTERVAL=1;',
number_of_arguments=>0,
enabled=> true);
END;
--set raise_events attribute = job_succeeded for main job
BEGIN
DBMS_SCHEDULER.set_attribute ('CLIENT.LOAD_DATA', 'raise_events', DBMS_SCHEDULER.job_succeeded);
END;
--Event Job that will send email based on condition. Condition is checked in procedure CLIENT.p_check_sendmail; If errors are found in the exception table, this job will raise exception and will be JOB_FAILED status. This job will send a email notification.
BEGIN
DBMS_SCHEDULER.create_job (       job_name          => 'CLIENT.EMAIL_JOB',
job_type          => 'PLSQL_BLOCK',
job_action        => 'BEGIN CLIENT.p_check_sendmail;                                   END;',
event_condition => 'tab.user_data.event_type = ''JOB_SUCCEEDED'' and tab.user_data.object_name = ''LOAD_DATA''',
queue_spec        => 'sys.scheduler$_event_queue,AGENT',
enabled          => true);
END;
BEGIN
dbms_scheduler.add_job_email_notification ( job_name => 'CLIENT.EMAIL_JOB',     recipients => '[email protected]',events => 'JOB_FAILED');
END;
Is the way i am subscribing to the event queue correct? Could you please share an example/document of event based job in a schema other than SYS and how subscription is being done to event queue?
Thanks

Hi,
It's a good decision you made because you shouldn't create objects in the SYS schema. I see you're using the add_job_email_notification procedure, so I'm assuming you're on 11g onwards.
This procedure is meant to make the job easy for you. That is, you don't need to worry about setting up AQ, the procedure does it all for you. All you need to do is setup the mail server if not already done, and call this procedure to add the mail notification. That's it.
You can also specify a filter to the add_job_email_notification procedure, so maybe you could specify directly your CLIENT.LOAD_DATA job to this procedure.

Procedures and Links being stored in sys schema

When I create database links and procedures when logged in as user A, it creates them under the sys schema and says that sys is the owner. When I run
SELECT db_link, username, password, host, created
FROM user_db_links; as user A the link shows up.
User a has create link priviledge.
I'm using APEX 3.0 and I'm getting a db link not found error. The link works through sqlplus. I have another identical user where this does not happen and the link is created under the schema I'm logged in as.
Thanks for any help.

Hi Stuart,
We'll probably need some more information to have an idea what might be going on. What is different about the working TestStand program and the other (version, configuration, etc)? Are we talking about the same database?

Meaning of the term " Schema "

Folks
I just want to know the general meaning of the term " Schema " in the database development perspective and from an Oracle perspective.
It will be very helpful if you explain to me in a simple way because I am very new to the Database field
Just started learning sql , pl/sql in ORACLE XE.

Matt wrote:
I just want to know the general meaning of the term " Schema " in the database development perspective and from an Oracle perspective. A schema can be many things.
Typically a schema is what you would call a database in SQL-Server and mySQL. In other words, it is a container for a logical database. Where this logical database consists tables, indexes, stored procs, views, triggers, etc. etc.
A schema also can be used as a user account. For example, schema DB1 is used as a logical database schema. Schema JOHN is created for John Doe to logon to Oracle and use the DB1 logical database. DB1 in this case will need to grant JONH access to its objects (and this way different user schemas can have different rights and access to a logical database schema).
Or a schema can be container for common code. A lot of PL/SQL based applications will have a set of common packages and functions and procedures. This can be stored in a schema that acts as a common code library. The code will typically be defined using caller rights (meaning that if the code is called by schema FOO, the code executes with FOO's rights). Public execute rights are granted.
A schema can be an application schema for a 3 tier system. The application tier (Java system running in JBoss for example) does the user authentication. This app tier needs to talk to the database (i.e. logon using a schema). In this case a special schema is created for the app tier (a so-called "trusted" schema as the database trusts the app tier to authenticate the users in order to gain access to the database). This app schema will then (similar to the JOHN user schema) have rights on the logical database schema.
A schema can be a full blown application framework. Oracle's Apex is an example. Its schema contains the Apex runtime engine and Apex RAD GUI. You develop your application inside this framework (which is stored as data in this app framework schema). This Apex app you develop will usually in turn use a logical database schema.
A schema can also be a combination of some of the above.
The SYS schema for example is the core of the database and contains (amongst others) the data dictionary of the database.
There is a special schema that contains the XMDB (XML database) feature of Oracle.
So Oracle itself uses the concept of containers to bundle specific feature sets together in a logical and secure way.
Schemas can also be physically separated from one another. The DB1 logical database schema can for example use its very own physical storage (Oracle tablespaces).
The great thing about a schema is that it can fill a number of roles - as it provides a secure container and in turn security layers can be created between containers to allow one container (e.g. user schema JOHN) to access/use objects of another container (e.g. logical database schema DB1).
And correctly using schemas are important for flexibility, maintainability and above all, security.

I load a package into SYS schema but cant resolve references made from a different sc

I loaded javamail-1.2 (and associated dependencies) into the SYS schema, just because it has classes under the same package root "javax".
If I try to load a second class having an import like "javax.mail.*" into a schema other than SYS, I get a message "can't find xxx".
How can I make the SYS new classes visible to a different schema?
Thanks for any help.

1) A WHEN OTHERS exception handler that does not re-raise an exception is almost certainly an error. In your case, you are writing the error message out via DBMS_OUTPUT, but unless your front end happens to try to read and display the DBMS_OUTPUT buffer, the error will be ignored. You realistically want to remove that exception handler.
2) Creating an index will not raise a NO_DATA_FOUND if there is no data in the table, so that exception handler is superfluous.Thank you very much, now that I removed that Exception it is telling me insufficient rights.
3) If you want User A to be able to create an index in User B's schema, User A would need to be granted the CREATE ANY INDEX privilege (directly, not via a role). If you are getting a permissions error creating the index after removing the incorrect exception handlers, that is likely the problem. If you are getting a permissions error dropping the index after removing the incorrect exception handlers, you would need to ensure that User A has been granted the DROP ANY INDEX privilege.I thought that since I had specifically granted the INDEX privledge to SchemaA on a specific table in SchemaB that Schema A would be able to drop and create indexes on that specific table. However.. having just looked again at the documentation it would seem that I would need to be able to do exactly as you say and have the ANY to be able to create it in another schema.
4) Since the various ANY privileges (CREATE ANY INDEX, DROP ANY INDEX, etc) are rather powerful and not restricted to a particular schema, is there a logical reason not to put this code in Schema B to begin with?Nothing in particular other than attempting to keep it all with the "parent" schema so that the select into's are run from the parent and populate the child (schemab). I guess I can have Schema A call the package in schema B and execute it however will that execute as Schema A or B?
Thanks for such a fast and detailed response

Some objects in sys schema not imported usinf full database import/export.

Hello All,
We need to migrate database from one server to new server using same database version 11g Release 2 (11.2.0.1.0). We have some production objects in sys schema.

second you are useing version 11gr2 what not you go for datapump export/import method.
third, did you get any error in import, what is the error

SYSTEM tbs doesn't increases... I cannot understand, where the segments that belong to SYS and make it so bog go..
Please, tell me where to look and chek, what the heck is going on and is coercing SYS schema to grow...

Error when adding columns to table and update sync group schema

Hi,
I have an Azure SQL Database that is synced to five lokal SQL Server Express 2012 clients. Today I had to add some columns to the tables, I did this using SMMS and ALTER TABLE on the hub-database.
Then I disabled auto-sync in the Azure Portal and updated the sync schema.
The first error I got when clicking on Save-Button was that my goup is not ready for syncing. I assumed that was caused by two sync agents who were offline. So I deleted them from the group and the error was gone. (is this an generall issue that all agents
must be online to update the schema?)
But then I got the next error when clicking on Save-Button who tells me SQL Error 207, invalid column name on the new columns I've added.
Here's the error in the eventlog:

Hello,
When you alter the table on hub database, did you specify the new column allow NULLs or have a DEFAULT? The column must allow NULLs or have a DEFAULT for the user to create it in the other tables on the sync group.
Reference:Add or remove a column in a sync group
If the issue persists, you may try to delete the sync group and recreate the group.

Decompile applet and proxify all URL and socket connection and recompile

Hi,
Please anybody have idea for the below.
I need to decomple the applet class file to .java file and need to change all URL and Socket connection to proxify all connections from applet. and recompile the sample applet to make ready to load in browser.
Thi is to load the applet form the web server through one proxy server. In the proxy server side While loading the applet from web server that applet code need to be changed to modify the URL and connections used in that applet to change the further connection from applet through proxyserver.
Compile and decompile is not a problem that i can use javac and javap respectively.
But I want to know how to change all URL and connection in applet. is there any easy way to handle this with out changing the applet code.
can Anybody help me.
Thanks and Regards,
Shiban.

Not sure how you do that:
Client <----[HTTPS]-----> Secure Gateway <------[HTTP]------->Web servers
or
Internet Explorer/Mozilla <----[HTTPS]-----> proxy <------[HTTP]-------> Google
Is the above correct?
If so than what are the proxy settings in IE/Moz, I can specify the proxy address in the
browsers but not the proxy type (SSL).
When you want to visit a page like google I gues you just type http://www.google.com in
the browsers address bar. The browser will figure out how to connect to the proxy.
Java has got the control panel in the general tabl there is a button "network settings...:"
I have it to "use browser settings" and this works for me.
All URL and URLConnections work but the sockets don't (maybe put in a bug report)
for example games.yahoo.com -> card games -> bridge -> create table
In the trace I can see:
network: Connecting http://yog70.games.scd.yahoo.com/yog/y/b/us-t1.ldict with proxy=HTTP @ myproxy/00.00.00.00:80
network: Connecting socket://yog70.games.scd.yahoo.com:11999 with proxy=DIRECT
The second one fails because port 11999 is not open (what idiot uses an unassigned
port for a profesional site is beyond me).
http://www.iana.org/assignments/port-numbers

Even if the port was open on the proxy you'll notice with proxy=DIRECT that
"use browser settings" does not work with socket (bug report??).
Anyway my advice is to open the java console (windows control panel or javacpl.exe in
the bin dir of java.home) and make sure it is set to "use browser settings"
Then enable a full trace:
To turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
if you cannot start the java console check here:
C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
I think for linux this is somewhere in youruserdir/java (hidden directory)
add or change the following line:
javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
for 1.5:
deployment.javapi.jre.1.5.0.args=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
I think for linux this is somewhere in youruserdir/java (hidden directory)
Print out the full trace of the exception:
try{...}catch(Exception e){e.printStackTrace();}
Then visit the games.yahoo and try to create a new table playing bridge.
Inspect the trace and see if it works/why it doesn't work.

Blobs and refreshing the schema

Hi all,
I have two questions about Kodo 3.3.3.
1) About blobs. A blob is the serialization fof an object. Does Kodo store
the hashCode of the class (ir the serialVersionUID of the class) that was
used to serialize the object ? Will I have a problem if I want to get back
that blob with a recompiled version of that class, with a different
serialVersionUID ?
2) About the XML descriptors of the schema. I configured my mappingtool to
write the XML descriptor of the my schema in the base, it works very fine.
I can get these descriptor, class by class, with the command mappingtool
-a export -f dump.xml package.jdo, it's very handy. From the
documentation, I red that one can export this XML, edit it, import it back
in the base, and refresh the schema
(http://www.solarmetric.com/jdo/Documentation/3.3.3/docs/ref_guide_mapping_factory.html).
My problem is : I cant find the command to perform this refresh, the
schema is just not "synchronized" with the XML. Any hint ? :)
Btw, I came across a bug using SQL Server : a field named "index"
generated a column named "index", SQL Server was quite angry at that.
Sorry if this one is know already.
Thanks for your answers,
Jos__

that blob with a recompiled version of that class, with a different
serialVersionUID ?Kodo just serializes the field value to a byte array using standard Java
serialization. So yes, you will have problems if the serialVersionUID of the
class changes. If you want more control over this process, you can create a
custom DBDictionary that overrides the serialize() method. Or you can use a
field of type byte[] and a byte-array mapping rather than a blob mapping, so
that Kodo doesn't do any serialization.
My problem is : I cant find the command to perform this refresh, the
schema is just not "synchronized" with the XML. Any hint ? :)Use the schema tool to synchronize the schema with the XML. See:
http://www.solarmetric.com/Software/Documentation/latest/docs/ref_guide_schema_schematool.html

Sorry if this one is know already.Thanks. We'll make sure this is fixed in Kodo 3.3.4.

Inline plsql_optimize_level=3 and recompiling the sys schema??
