Authenticating 10g databases against OID 11g

Hi.
Our client currently uses OID 10g to authenticate users on their 10g databases. They intend to begin an upgrade to 11g beginning with the OID upgrade. Some applications though are likely to remain on 10g databases for the foreseeable future.
Will it remain possible to authenticate existing 10g database installations against the new OID 11g setup?
If so, will this happen automatically as part of the OID 10g->11g upgrade steps?
Many thanks.

Hi Sridhar
Did you come right with the Oracle case insensitive connection? I am at a client site and they are asking if I can create an Oracle case insensitive connection and need to know how to do this.
I have come right now. I have added the following into the parameters in the universe:
NTS_COMP = LINGUISTIC
NTS_SORT = BINARY_CI
When running a query the selection does not have to be case sensitive. eg. In the database it shows as "SOFTWARE" and if I run a query looking for "software" it returns the correct data.
Thanks
Sharon

Restoring Back To 10g After A Failed 11g Upgrade Of a RAC Database

I'm testing this out on a small test RAC database. I successfully upgraded it from 10.2.0.4 to 11.2.0.2 but wanted to test the scenario of having to go back to 10g if the upgrade really hosed up. The first recovery attempt seemed to be successful but after bringing the DB down with srvctl, it failed on the next startup saying it needed to be started in upgrade mode. Something from 11g was still in place or the fact that I was trying to restart a 10g database managed by 11g clusterware was the issue. I tried starting the DB from both 10g and 11g environments and got the same result. Even starting each instance individually got the same result.
In all that I tried, I got the usual incarnation and "until time before reset time" messages. I've been doing this all through RMAN without EM or Grid Ctl. As usual, any docs I found have had just a little information and I have to piece my own instructions together from all of them, not knowing for sure it all steps would apply in my situation.
Can anybody point me to a good doc or other resource that might help me out? Many thanks!

Now I have a different issue with apparently the same problem. I successfully did the restore/recover as before but the thing pukes when I open resetlogs at the end. Something, somewhere is still pointing to 11g but I have no idea where or what has changed since the last time I did this. Maybe I've messed things up by doing this multiple times. Here are my RMAN commands:
RMAN> connect target
RMAN> startup force nomount;
RMAN> RESTORE SPFILE TO '+DATA/jimg/spfilejimg.ora' from '/local/oracle/10.2.0/db_1/dbs/c-2526333028-20110915-01';
RMAN> shutdown immediate;
(in a different session, from command line)
% mv /local/oracle/10.2.0/db_1/dbs/initJIMG1.ora.bak /local/oracle/10.2.0/db_1/dbs/initJIMG1.ora
RMAN> startup force nomount pfile='/local/oracle/10.2.0/db_1/dbs/initJIMG1.ora';
RMAN> restore controlfile from '/local/oracle/10.2.0/db_1/dbs/c-2526333028-20110915-01';
RMAN> alter database mount;
RMAN>
run {
restore database;
recover database;
RMAN> alter database open resetlogs;
The errors I get after resetlogs are:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of alter db command at 09/16/2011 09:24:50

This is being done on a small, expendable database for practice. I think I've learned enough about what NOT to do to keep me from getting in this jam to begin with. Any thoughts?

Preparing for Oracle OCA 11g using an Oracle Express 10g database

As a software application developer, I have been considering Oracle certification for a while to enhance my skill set. Unfortunately I don't have access to a commercial Oracle installation, and would like to use a free version of Oracle Express during my studies. The latest OCA courses largely focus on Oracle 11g, and it would appear that there is no free (Express) 11g database available yet.
Could anyone please advise me whether it would be possible and practical to prepare for the 1Z0-051 Oracle Database 11g: SQL Fundamentals I and 1Z0-052 Oracle Database 11g: Administration I exams using an Oracle Express 10g database instance, while accompanied by the relevant Oracle 11g study material? In other words, is the overlap between Oracle 10g and 11g sufficient that a solid understanding of 10g could allow me to successfully sit the 11g exams? Furthermore, would the Express edition of the database provide sufficient functionality to prepare for the Administration exam?

(http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_org_id=1080544&lang=US&p_exam_id=1Z0_051 says Exam 051 has been validated against Oracle Database 10g and Oracle Database 11g. Training on either version will be appropriate preparation.).
For 1z0-052 the situation is different. Oracle 10g express edition hides some of the administration tasks ... you really need to be using 11g.
If you dont waht Oracle 11g all over your regular machine then I would typically recommend install Oracle Enterprise Linux either on a spare machine with a dual core or HT processor and with 2GB or more of memory (eg Dell gx280 or better); or using a virtualisation solution on your current machine (ram would need to be 3GB or higher) (eg virtualbox or whatever ... though windows as a guest can have a license issue).

Reports 6i against 10g database

Hi,
We are upgrading our database from 9i to 10g. We are running our reports (6i) against 10g database in the batch mode. For some of our reports we are getting the following error:
REP-0736: There exist uncompiled program unit(s).
REP-1247: Report contains uncompiled PL/SQL.
When report is opened in ReportBuilder it needs to be recompiled against 10g and then it runs fine.
Please advise how to solve this problem.

This is not because of the database is changed. Some of the packages/program units compilation dates might have changed and hence reports wants it to be recompiled.

Hi Pete
I encountered the same problem in Oracle Forms 10g (9.0.4.0.19) with an Oracle 10g database. My error was caused by default values in the form of a function call in one of the procedures functions
f.e.
package my_package
function my_function
( par1 varchar2
, par2 varchar2 default my_function_in_another_package
) return varchar2;
end;
Remove the default value in the function parameter par2 and everything works fine
Hope this helps,
Matthieu

You mght not, however do it the other way . . .

Importing a few Oracle 10g schemas into oracle 11g database

Hi,
I have the task to import a few schemas that are on oracle 10g database (10.2.0.4) into oracle 11gR2 database (11.2.0.2). Now I have only oracle 10g export and import utility (the 11g server is in not where I am given the import rights).
Can I do the export of the 10g schemas using the 10g export utility and then import into 11g database using the 10g import utility? I ran a test to do that and found it works but would also like to have expert opinion on it.
Also another question is: if the source schema is 11g - suppose- in that case can the 10g export/import utility still work? I mean export the schema from say db1 (which is 11g) using 10g export utility and import them into 11g database db2 (which is again 11g) using 10g import? I am asking because I don't have access to 11g server and trying to find what I can do with the 10g utilities.
Thanks,

set up a database link to the 10gR2 version database in the 11gR2 database.
Now using the 11gR2 client impdp utility use
impdp network_link=<link to 10gR2 database>
Done.
Your 'objection' you don't have access to 11gR2 doesn't count as you can install a 11gR2 client.
Also generally speaking you should not use a lower version imp to imp to a higher version database
Also exp and imp are deprecated in 10g and higher.

WAY TO IMPORT DATA FROM 11G DATABASE TO 10G DATABASE?

Hi All,
I have a requirement to take an full export dump of an Oracle database and import it fully to a 10g database.
I have never touched 11G until now and would like to know whether the 11G expdp will be downward
compatible so that I can use the dump file(created by 11G expdp) to import it to 10G(using 10d impdp).
Or if it is not possible, can you please brief me the steps I should follow here?
Note: I have only 11G installed in this server.
Regards
Satish

Oracle's Data Pump (expdp) utility has a VERSION parameter. Here is an excerpt from the documentation:
VERSION
Default: COMPATIBLE
Purpose
Specifies the version of database objects to be exported. This can be used to create a dump file set that is compatible with a previous release of Oracle Database. Note that this does not mean that Data Pump Export can be used with versions of Oracle Database prior to 10.1. Data Pump Export only works with Oracle Database 10g release 1 (10.1) or later. The VERSION parameter simply allows you to identify the version of the objects being exported.
Syntax and Description
VERSION={COMPATIBLE | LATEST | version_string}
The legal values for the VERSION parameter are as follows:
    * COMPATIBLE - This is the default value. The version of the metadata corresponds to the database compatibility level. Database compatibility must be set to 9.2 or higher.
    * LATEST - The version of the metadata corresponds to the database version.
    * version_string - A specific database version (for example, 11.1.0). In Oracle Database 11g, this value cannot be lower than 9.2.
Database objects or attributes that are incompatible with the specified version will not be exported. For example, tables containing new datatypes that are not supported in the specified version will not be exported.
Here is a link to the documentation.
Hope this helps!

We are planning to migrate them and upgrade to 11g rel2 on linux machine
and finally merge those into one database as different schemas
has anyone got good ideas of the best strategy to do that

ORA-06553: PLS-908 when calling 10g remote procedure from 11g database

Hi,
I have 2 instances: 11g (11.1.0.7) and 10g (10.2.0.4). When I try to call 10g (remote) procedure from 11g database, there is errors:
ORA-04052: error occurred when looking up remote object CUSTOMER.PRL_PK2_GENERAL@CUSTOMER_LINK
ORA-06541: PL/SQL: compilation error - compilation aborted
ORA-06553: PLS-908: The stored format ofCUSTOMER.PRL_PK2_GENERAL@CUSTOMER_LINK is not supported...
But, if I call the same procedure from another 10g instance, it's OK.
How can I fix the problem?
Thx,
qtpham

As you can see ,it seems like the workaround that was mentioned there is currently the only way to remove this ORA.
Workaround: Remove the function call(s) from the called subroutine's
package's spec.

Making a procedure to work against 8i, 9i and 10g databases

Hello all,
I made a procedure that gathers info from user. At some point I execute this part of code:
CURSOR tabPrivs IS
SELECT owner, table_name, privilege, grantable, hierarchy
FROM dba_tab_privs
WHERE grantee = uName;
At first my procedure was only for 9i and 10g databases. I tried it once on 8i and get the logical error that the hierarchy column doesn't exist in the table dba_tab_privs.
I want my procedure to work against all versions of databases so I tried to do an additional select if the database version was upper than 8, but it seems that it won't compute, as if before executing my procedure, the engine look to all the select I am trying to do and check if they are correct.
I want to know if there's a work-around because I want to provide the most generic procedure possible.
Thank you,

You need to declare your cursor according to your DB version. Something like this might keep you going:
DECLARE
   VERSION         VARCHAR2 (30);
   COMPATIBILITY   VARCHAR2 (30);
   uname           VARCHAR2 (30);
   TYPE cur IS REF CURSOR;
   p_sys           cur;
BEGIN
   DBMS_UTILITY.db_version (VERSION, COMPATIBILITY);
   IF VERSION LIKE '10%' OR VERSION LIKE '9%'
   THEN
      OPEN p_sys FOR 'SELECT owner, table_name, PRIVILEGE, grantable, HIERARCHY
           FROM dba_tab_privs
          WHERE grantee = :uname' USING uname;
   ELSIF VERSION LIKE '8%'
   THEN
      OPEN p_sys FOR 'SELECT owner, table_name, PRIVILEGE, grantable
           FROM dba_tab_privs
          WHERE grantee = :uname' USING uname;
   END IF;
   do_your_fetch_and_work_here;
   CLOSE p_sys;
END;
