Why do packages go invalid ?

Hi,
Whenever I do a DDL to a table or re-create existing functions, dependent packages/ functions go invalid.
Is there a reason for this?
Thanks!
Anand

Yes all dependent objects will go to invalid state and oracle will autocomplie when they will get accessed. OR you need to compile all or manually compile selected objects.
You can find dependencies from below query for the modified objects.
select * from DBA_DEPENDENCIES
where owner = 'PROVIDE SCHEMA_NAME'
and name = 'PROVIDE OBJECT_NAME'

Valid packages goes invalid when executing application

Friends of pl/sql
When we execute our application we find that 2 of our main packiages go invalid for no reason. The packages compiles just fine when we then compile them. So, no syntax errors. But it stops our application with a lovely "existing state of packages have been discarded......." type error. Not too nice.
What are some of the things to check on for why the package goes invalid ?
We are using TOAD and sql*monitor to trace the process at the moment...........
Any solutions out there ?

One of my older standard responses (haven't use this in a while)..
Packages tend to fail because of their "package state". A package has a "state" when it contains package level variables/constants etc. and the package is called. Upon first calling the package, the "state" is created in memory to hold the values of those variables etc. If an object that the package depends upon e.g. a table is altered in some way e.g. dropped and recreated, then because of the database dependencies, the package takes on an INVALID status. When you next make a call to the package, Oracle looks at the status and sees that it is invalid, then determines that the package has a "state". Because something has altered that the package depended upon, the state is taken as being out of date and is discarded, thus causing the "Package state has been discarded" error message.
If a package does not have package level variables etc. i.e. the "state" then, taking the same example above, the package takes on an INVALID status, but when you next make a call to the package, Oracle sees it as Invalid, but knows that there is no "state" attached to it, and so is able to recompile the package automatically and then carry on execution without causing any error messages. The only exception here is if the thing that the package was dependant on has changes in such a way that the package cannot compile, in which case you'll get an Invalid package type of error.
And if you want to know how to prevent discarded package states....
Move all constants and variables into a stand-alone package spec and reference those from your initial package. Thus when the status of your original package is invlidated for whatever reason, it has no package state and can be recompiled automatically, however the package containing the vars/const will not become invalidated as it has no dependencies, so the state that is in memory for that package will remain and can continue to be used.
As for having package level cursors, you'll need to make these local to the procedures/functions using them as you won't be able to reference cursors across packages like that (not sure about using REF CURSORS though.... there's one for me to investigate!)
This first example shows the package state being invalided by the addition of a new column on the table, and causing it to give a "Package state discarded" error...

Package owner - invalid packages

Hello guys,
I have this problem: I have two DB schemes A and B. I modified the code in both schemes. After compilation, many packages were invalidated. So I compiled all invalid packages, no compilation errors, everything ok.
Now if I run this query in scheme A:
SELECT *
FROM ALL_OBJECTS
WHERE OBJECT_TYPE IN ('PACKAGE', 'PACKAGE BODY')
AND STATUS = 'INVALID';I get two records.
The first one shows an invalid package where owner is scheme C - this is ok, because in scheme C is really such invalid package which has granted execute to scheme A.
The second one shows an invalid package body, where owner is scheme A. But in scheme A, there is no such package. The "invalid" package is in fact in scheme B, it is in fact not invalid and it has no grants at all. So scheme A has no access to that package at all.
Recompilation of this package in scheme B has no impact on the result. Why is the package marked as invalid and why is scheme A assigned as an owner???
Now I run exactly same query in scheme B and get one record.
One package is marked as invalid where owner is scheme B. However this package is in scheme A and scheme A is the owner of this package. Again the package is not invalid and recompilation of that package has no impact... In this case the package has granted execute to scheme B, so scheme B has the access to this package.
Can anyone help me with this?
Thanks, Dan

I found the problem...
After I did those changes to that packages, I first compiled the bodies to wrong schemes. So the bodies were created without specifications. I didn't see those packages because SQL Developer doesn't display them in such case...
So I droped them now.

Package gets invalidated seemingly at random

Hi, I am experiencing a problem whereby a PL/SQL package is valid for same time (and runs succesfully a few times) and then suddenly becomes invalid in DB. If I recompile package it works for some time and then again gets invalid.
Do you know what might cause such strange behavior.
Also, does anyone know a way of obtaining error information from DB that reports why a package was flagged as invalid?
Also, does anyone know how to obtain dependencies (both direct and indirect) for a package?
Thanks for your help, regards,
-Javier

Thanks a lot Gio for your help. I was asking how to onbtain dependencies just because of the reason you mention.
However if I run your query I get a dependency from the package body on the package. If I run the query on the package body (which is the one that gets flagged as invalid every once in a while) it does not return any dependency.
In fact there are quite a few tables accessed inside the package but the query does not return a dependency on them. Nevertheless those tables are not supposed to be altered, and this problem repeats every day which makes me think that is not the problem.
Thanks a lot,
Javier

Hi Peter,
I cannot cut and paste , I tried it.
Just phoned my service provider, the operator I spoke with has the same phone as mine and she said that when I am entering the codes that when I get to the + sign I should just hold it down and it will change to the + sign, but mine doesnt. Mine gives me 3 choices, 1. add new contact 2. add existing contact, 3. cancel.
It doesnt matter how long I hold the + sign down for
Does anyone know of a solution please, its driving me mad lol

The extension package is invalid

The extension package is invalid. The extension will not be
installed.
When attempting to download and install extensions from the
Dreamweaver extensions listed at the Adobe Dreamweaver Extension
page I receive this message.
Any solution?
I am running Dreamweaver 8 on a PC. The OS is Vista. Don't
tell me Vista is at fault. It will occasionally install an
extension just fine. Most of the time it won't.

What extension? Have you checked the specs to see if your OS
is supported?

Occasionally? I think you have your answer. Dreamweaver 8
came out a year
before Vista did. Many of the extensions on the Exchange may
not even
support 8 .. many of them do. Make sure 8 is supported in the
extensions
you are trying to install. As for Vista .. I don't have it so
it's hard for
me to comment. I have seen enough however that I'll probably
wait at least
a year and let them put out a better version before I take
that plunge.

So, could anybody suggest, what to do now and how to proceed to make this package valid ?

Nitesh,
So, could you help me to know the source where i can find the valuable information related to this.To find the pls for package creation, you can also do the following in your appl_top.
-> Go to the product top/patch/115/sql
-> grep -i fnd_securit * | grep -i create
You'll get an output something like this
AFSCGRPB.pls:create or replace package body FND_SECURITY_GROUPS_PKG as
AFSCGRPS.pls:create or replace package FND_SECURITY_GROUPS_PKG as
AFSCUSV8.pls:CREATE OR REPLACE PACKAGE BODY fnd_security_pkg wrapped
AFSCUSVS.pls:CREATE OR REPLACE PACKAGE fnd_security_pkg AUTHID DEFINER AS
afpub.sql:CREATE SYNONYM FND_SECURITY_PKG FOR &1..FND_SECURITY_PKG;
afsecctx.sql:REM | Creates the fnd_security context and invalidates any obsolete
afsecctx.sql: execute immediate 'create context fnd_security using fnd_security_pkg';
In these you would need the pls related to FND_SECURITY which are AFSCUSV8.pls and AFSCUSVS.pls
-> sqlplus apps/apps @AFSCUSVS.pls (Spec)
-> sqlplus apps/apps @AFSCUSV8.pls (Body)

Error message: Package contains invalid characters installing patchlevel 6

Dear experts:
I have successfullly installed SAP GUI 7.20 compilation 2, using SAP installation server (40 machines, Windows XP sp3 32 bits, latest updates).
I have successfully installed patchlevel 6 in the SAP installation server. (gui720_6-10007878.exe, downloaded from SAP Portal)
SAP GUI is configured to search for updates after 5 double-clicks on desktop icon. I forced the 5 double-clicks on a test machine and the patch begins to install; then informs me that there is a pending reboot.
When I reboot the machine a SAP Netweaver Front-end installer window appears with the error: "/Package contains invalid characters like /*?"<>\" - "Your system has a pending reboot". If I reboot again the message is displayed again.
If I click on the "Cancel" button of this window, Windows XP continues booting and SAP GUI works fine.
Two questions:
How can I avoid the installation of this patch on all the machines?
What can be wrong?
Thank you very much.
Mr.Clinker
Uruguay - South America.

1.) To avoid the installation on all clients simply go to "Services -> Configure Automatic Workstation Update Service" in the SAP Installation Server Administration Tool and disbale the service. If this doesnt work you can delete the package on the installation server an create a new one with the same name. You can than patch the package to the patchlevel you want.
2.) Try to apply patch 6 Hotfix 2 and see if the problem remains.

How to find the status of package (valid/invalid) was at a particular time

How to find the status of package (valid/invalid) was at a particular time ?
I want to find the status of one oracle package at 3pm yesterday. The status of this package today is INVALID.
I am sure it was VALID yesterday. But no way to prove it. Can any one help please???
I can generate AWR report for last 7 days...

Try using a flashback query, like this:
select object_name, object_type, status
from dba_objects AS OF TIMESTAMP (SYSTIMESTAMP - INTERVAL '18' HOUR) -- 18 hours ago
where object_name = 'MY_OBJECT'
;if you haven't granted FLASHBACK privs, you may need to connect as SYS to do a flashback query on a data dictionary table.
But this should give you the info you need - if it's still in undo.

If "String[ ]args" is a valid syntax, why "int( )func" is invalid?

May sound stupid but,
If "String[ ]args" is a valid syntax, why "int( )func" is invalid ?

I know Java creators have made String[ ]args as valid for easy understanding and readabilityThey did that to effect a major improvement over the confusing 'C' syntax. In 'C', if you haveint a[], b, c, d; (i) the 'array-ness' only applies to a; (ii) you have the datatype distributed on both sides of the variable name; (iii) you have multiple datatypes being declared in one line of code (both int and int[]). All of which Gosling (and I) found counter-intuitive. In Java if you writeString[] a,b,c;they are all arrays, and the entire datatype is on the left before any identifiers. It's a better syntax.
but isn't this same procedure can also be followed in functions?But (a) the current syntax isn't confusing or counter-intuitive; (b) changing it wouldn't improve 'easy understanding'; and (c) multiple functions aren't declared in a single line of code anyway.
So your question is pointless.

DBMS_JOB using Packaged Functions but Package goes invalid

Is there any way to check a package while running a PL/SQL procedure to see if it's state is valid and then catch the exception?
In my case usually just calling any function in the package 1x clears it up but the procedure in question runs as a DBMS_JOB it just keeps failing. This procedure could run often enough that Oracle will mark it as broken but I want to give it every shot at execution on time instead of having to make it wait till the next cycle.
What I would like to do is to catch the exception for the package state being invalid and basically have it go back to the beginning of the procedure and give it another try before failing in case it is just a failure because the package has been altered.
Is there any way to do this?

Firstly, I'll copy/paste my standard response regarding package state going invalid as it usually helps to have an understanding of these things...
Packages tend to fail because of their "package state". A package has a "state" when it contains package level variables/constants etc. and the package is called. Upon first calling the package, the "state" is created in memory to hold the values of those variables etc. If an object that the package depends upon e.g. a table is altered in some way e.g. dropped and recreated, then because of the database dependencies, the package takes on an INVALID status. When you next make a call to the package, Oracle looks at the status and sees that it is invalid, then determines that the package has a "state". Because something has altered that the package depended upon, the state is taken as being out of date and is discarded, thus causing the "Package state has been discarded" error message.
If a package does not have package level variables etc. i.e. the "state" then, taking the same example above, the package takes on an INVALID status, but when you next make a call to the package, Oracle sees it as Invalid, but knows that there is no "state" attached to it, and so is able to recompile the package automatically and then carry on execution without causing any error messages. The only exception here is if the thing that the package was dependant on has changes in such a way that the package cannot compile, in which case you'll get an Invalid package type of error.

Secondly, from this above standard response, you can see how to check for package state if you want to determine it programatically.

HT3702 Why does it say invalid security code when I'm prompted to sign in?

Why does it say invalid security code when I'm prompted to sign in. I have intered my security code from my credit card several times. It will not allow me to use the app store, even for free purchases.

Is the address on your iTunes account exactly the same (format and spacing etc) as on your credit card bill : http://support.apple.com/kb/TS1646 ? If it is then you could try what it says at the bottom of that page :
If the issue persists, contact your credit card company and verify that they and any company they use to process credit card authorizations have the correct information on file.
And/or try contacting iTunes support : http://www.apple.com/support/itunes/contact/ - click on Express Lane, then iTunes > iTunes Store

Why do packages go invalid ?
