SQL Plus session - "schema.package" has been invalidated on making any chng

Hi
I am in the process of testing a stored procedure. Whenever I make changes to the procedure I am executing it from the SQL Plus session. But whenever I make a change to the procedure - i have to close that particular SQL Plus session and open another one. I get the message:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-04061: existing state of has been invalidated
ORA-04061: existing state of package body
"schema.package" has been invalidated
ORA-04065: not executed, altered or dropped package body
Is there a way that I do not have to open a new SQL Plus session everytime I make change to the package?

It does not help :(. I get this problem in a SQL+ session only when I make a change in a JDev session. I have to log off the SQL+ session and log back in and it is OK again without re-compling anything. I don't have a problem with two SQL+ session. Isn't that strange?

Existing state of packages has been discarded...

Hi all,
I know this is a long shot and probably you need more details to help, but please take a look in case you've encountered something similar before... It is a pretty interesting problem.
Ok, I have two packages, say, A and B. Package A is composed of utility functions, and package B makes use of those functions. These packages are compiled as part of the schema installation, where package A is always compiled first. I also have unit test scripts for each procedure in each package.
Now, after schema installation, when I run the unit test for some procedures in package B, I get the following error:
ORA-04068: existing state of packages has been discarded
ORA-04065: not executed, altered or dropped stored procedure "my_schema.pkg_A"
ORA-06508: PL/SQL: could not find program unit being called
ORA-06512: at "my_schema.pkg_B", line 18
ORA-06512: at line 5
Some interesting notes:
- I can run the unit test of all pkg A procedures. I can also describe the package. Which seems to me that pkg A has been compiled successfully.
- If I log into a sqlplus session, run the unit test for a pkg B procedure, which then fails with the above message. Then I run a unit test of a pkg A proceudre, which succeeds. Then I run the same pkg B unit test, it will work then. And all the other pkg B procedures will work from this point on.
- But if I log out from sqlplus session, and log in again, and run the pkg B procedure unit test again, it will fail as before.
- Certain procedures in pkg B have no problem running. They also call pkg A procedures. However, the pkg A procedures are always invoked in the where or order by clauses in these cases. The pkg B procedures that call pkg A procedure in a standalone statement will always fail.
- The fact above made me suspect that function-based indexes (which were created using pkg A procedures) were used in cases where pkg B procedures work. And that in those cases pkg A hasn't really been invoked. However, when I monitor those indexes using v$object_usage, it shows they are not used. (I have a very small set of data.)
- After schema installation, if I compile pkg B again, the problem will disappear.
Does this ring a bell to anyone? Any help will be appreciated.
Thanks,
Gloria Chung

Thanks for reading and responding.
I'm compiling both header and body for both packages.
I ran the following query after schema installation, which returned 0:
select count(*) from user_objects where status='INVALID';
The schema installation involved putting new copies of both package A and B.
If I only recompile the package body after installation, it will still 'cure' the problem. I.e. if I run any of the affected pkg B unit test, it will run successfully.
It is assumed there is no schema before 'schema installation'.
Thanks,
Gloria

Existing state of package has been discarded...

If application is running and it uses cursors/prepared statements for procedures and functions in packages and
new version of package is inserted into database, then an error message 'existing state of package has
been discarded' is raised.
However, there are packages where there is no 'existing state of package'. And for application purposes
new version of this package should be used without this error message.
Enhancement: There should be a pragma stating that package is 'stateless' and new version ot it is used if it
exists without an error situation.
This feature would be beneficial e.g. in 3-tier architecture where servers are running constantly.
Or can this be accomplished with any other way (without parsing statement with every call ) ?

When session references a package for the first time package is instantiated in session memory. If package is recompiled since, Oracle assumes it possibly changed and package instance in session memory is no longer valid. That's why any reference to that package made by such session will raise an error.

ORA-04068: existing state of packages has been discarded

I work on an order entry system that is up 24x7 running Oracle version 8.0.5. I want to compile a fix to a procedure contained in a package body. I only will be recompiling the package body. Since the package body has no dependent objects, I should not invalidate any stored procedures that call this procedure in my package. However, should I worry about causing an "ORA-04068: existing state of packages has been discarded" error? What causes this error and when does it occur?

Please ensure that DBMS_ROWID is created in SYS schema and not in any ordinary user's schema. If it exists in any user's schema drop it from there.
If the problem persists, drop the package from sys schema as well and run two script files in the following order:
1) ORACLE_HOME\rdbms\admin\dbmsutil.sql
2) ORACLE_HOME\rdbms\admin\prvtutil.plb

Setting security context in sql*plus session

Hi,
For a SQL*Plus session under an account that doesn't have execute privileges on fnd_global, is there any way to set the application security context similar to the way fnd_global.apps_initialize does?
For example, as APPS one can do this:
<br>
sqlplus apps/...
SQL> select SYS_CONTEXT('FND','USER_ID' ) as fnd_user_id from dual;
FND_USER_ID
1 row selected.
SQL> execute fnd_global.apps_initialize( ... );
SQL> select SYS_CONTEXT('FND','USER_ID' ) as fnd_user_id from dual;
FND_USER_ID
123456
1 row selected.What I'd like to do is something like this ...
<br>
sqlplus scott/...
SQL> ... call some EBizSuite procedure where I can supply or
be prompted for an EBizSuite user name, password, and responsibility ...
SQL> select SYS_CONTEXT('FND','USER_ID' ) as fnd_user_id from dual;
FND_USER_ID
123456
1 row selected.

Hi
Is there any method to initialize the environment using Java API.
how to call the function fnd_global.apps_initialize
Can you explain the required parameters.

My broadband package has been downgraded without m...

I wrote on here a couple of days ago as I was really annoyed at BT for cancelling my order for the Home Hub 4 which they ordered on my behalf - the order has disappeared off the MY BT page and I've no idea what happened, can only speculate. However, I've now logged back into My BT and found my broadband package has been downgraded from Unlimited Broadband to More Broadband!!! As far as I can tell, this means I've now got a limit of 40GB per month - I use that in a week!!
What the hell are BT playing at? Has anyone got these problems or have I been landed with the idiots??
Seriously considering cancelling the contract even though we are only weeks into it.

Certificate with PSE type SystemPSE has been invalid

Hi,
I got the following error in the log. Please advise.
Certificate with PSE type >SystemPSE< has been invalid for 733561 days
Regards,
Tony

Tony,
If you are not currently using SSO, you may want to clean up the System PSE at any time, to eliminate those log errors.
If you are actively using SSO, youu2019ll want to wait for off-peak hours or a maintenance window.
The following is based on having the system certificate and the portal SSO certificate. If you have more for other reasons, youu2019ll need to take more care and planning.
To do this, you will need to:
-     go to strustsso2
-     right click on System PSE (left panel)
-     select Delete
-     green arrow back all the way out of strustsso2 to the main screen
- Go back into strustsso2
- right click on create
- accept the default entries for u2018create PSEu2019
- click Save
- If you expand the System PSE on left, you should see your server name.
- Double click the server to show the system certificate.
- Then double click the certificate to see the details.
-     Finally, youu2019ll want to import your SSO certificate, add it to the Certificate List and add it to the ACL, and save.
Of course, all of this is if you want to have a cleaner system log. If you have any doubts before attempting, feel free to post as there are a lot of helpful people in the forums, and in this thread alone!
If everything is working as expected and you donu2019t mind ignoring the system log messages, then you can take no action.
Hope this helps!

How to block Sql Plus sessions in Oracle 10g

Hi,
I want to block all sql plus sessions in oracle 10g, as we have a application and we need each and every one to use this application not the sql plus session.
Kindly update us as soon as possible. and also thanks in advanced.

Understand the concept Karl, but a layered defense seldom works in the IP world. If I manage to get through the firewall, then how can you prevent me access, at IP level, at any other ISO stack layer? If you manage to get through, then your firewall policies could just be too weak :) at least you must have some kind of an IDS infrastructure in place..
what I mean is, you can have infinite number of threats.. and this will be part of your Risk Analysis. Determining all possible threats to the assets, what are being protected and their associated value, and predicting the rate of occurrence.... with all of these you could probably come up with contingency plans and incident response.. And most of all, you should not ignore the fact that people are creative, ingenious, and curious, and they'll prove this to you by testing your security implementations. So you'll have to periodically evaluate your security.. that's why there are audits.. Also, you must balance Security, Performance, Usability, and your Budget.
Yes, you can argue that if the entire firewall goes down (thus no IP defense), then something like DBV (or even denying IPs in sqlnet) can provide some defense. But is that not then a case of too little too late? It's better too little too late, than no protection at all... Imagine if there's no DBV, or if you have not implemented the concept of "Least Privilege"? or if the backups and exports are not encrypted? That would be more devastating.. that's the importance of database security options and features in providing "defense in depth"
I question just what purpose and how effective IP packet security is at higher layers. It can never substitute doing this instead at firewall level. Well, it's not all about network security. All facets must be considered and the inter-relationships should be understand. Like the core information security and access management, physical and personnel security, training them, etc... And all of these are equally important in providing a secure ecosystem
As for security that relies on the client to pass secure data (like executable name or o/s user name)... all this can easily be spoofed. Even if the app and Oracle driver are somehow digitally signed and these signatures can be verified on the server side, we only need to look at Vista to see how secure this really would be. Microsoft attempted to encrypt every single h/w and s/w layer from the physical DVD track to the pixel on the monitor.. and this was defeated. And this was done as o/s kernel level. It is less complex to hack at driver level and even trivial to do it at application level.Security is about risk management. Blocking SQL*Plus does not negate the risk of SQL from the wild being run on a production server. For example, the client is a VB client using ODBC. It is easy to create a proxy that accepts the ODBC connection from the VB client and proxy the OCI packets to the real Oracle server. Now you have a man-in-the-middle than can inspect every single SQL call made to Oracle, and inject any PL/SQL or SQL code it wants.
Security is far beyond writing a login trigger to deny SQL*Plus sessions and calling that a defense. >
Yes I agree with you. That's why there are independent organizations and regulating bodies that provides security best practices, to give us a headstart on comming up of strong security policies.
And one of my favorites is the one provided by IASE (sponsored by Defense Information Systems Agency) where there's lot of content regarding hardening and policies

I have bought a new Iphone 4S and also own a Mac pro, also IPad. I did not install find my phone on the IPad, my IPad has either been misplaced (have tore the house up looking for it) or it has been stolen is there any way I can find where it is at

I resently purchased the New IPhone 4S, and I have a mac Pro, plus a IPad. I have misplaced my IPad or it has been stolen is there any way by using Find My phone it can be located Thanks Look for My IPad

Unless you set up MobileMe / Find My iPad on it before it was lost/stolen, then no, there isn't any way to locate it. If you did set up MobileMe on it then you could try locating it either via me.com on a computer or Find My iPhone / Find My iPad on a another device - but that will only work if it's connected to a network and the device hasn't already been wiped and/or MobileMe disabled on it.
If you think that it was stolen then you should report it to the police. As a safety precaution you should also change your iTunes account password, your email account passwords, and any passwords that you'd stored on websites/emails/notes etc.

Sorry we are unclear as to the external hard drive and its connection to the TC..
For instance the light that blinks.. is that the TC or external hard disk or what.
Did you try just rebooting / restart the whole network in correct order.. modem.. router / TC.. external drive.. clients with 2min gap between each.
Are you actually running Snow Leopard as the profile states?
How old is the TC?
