How oracle deals with the setting of init.ora parameter compatible.
e.g. we have
DB Version=10.2.0.4
compatible=10.2.0
what is the possible leak for us ? Is there any description about the features changed in 10.2 up to 10.2.0.4 in all steps - so that we can check out which functions we do not have.
We are migratingfrom [IBM P5 - AIX 5.3 - Oracle DB 10.2.0.1 64bit]to [IBM P7 - AIX 6.1 - Oracle DB 10.2.0.5 64bit]
The new database is already up and running, our next step now is the following:
1. Create Tablespaces (done)
2. Export the Database from P5
3. Import the dump to P7.
We have this following options:
I. Use a Windows XP workstation 32bit with Oracle 10.2.0.1 Database software to export from P5, then import the dump to P7. (Export/Import Utility 10.2.0.1 Windows 32bit)
II. Use the Export Utility of the P7 (10.2.0.5 AIX 64bit) to do the export and import.
III. Use the Export Utility of P5 (10.2.0.1 AIX 64bit) then use the Import Utility of P7 (10.2.0.5 AIX 64bit)
BTW, our colleague tried to do the following:
A. Use Windows - Export Utility 10.1.0.2.0 - 32bit to make a dump of our database (Oracle 10.2.0.1.0 AIX 64bit)
B. Use Windows - Import Utility 10.1.0.2.0 - 32bit to import the dump file from step A to our new database (Oracle 10.2.0.1.0 AIX 64bit)
But after issuing imp system/password@NEWDB file=(a.dmp, b.dmp... c.dmp) full=y ignore=y statistics=none
The import seems to hang here...importing SYSTEM's objects into SYSTEM
is there a oratab file in window versions of oracle 11g xe?I found out that, oratab is:
associate with ORACLE_SID, ORACLE_HOME value, and you can input parameter like:
orcl:/opt/oracle/product/10.2.0/db_1:Y
to allow the datebase to be started when the server reboot.I am thinking for window versions, they are using 'SERVICES' right? That's why no oratab files?
Following is the scenario:
1. Oracle DB Binaries: 11.2.0.2.2
2. Using dbca to create General Purpose Database and then modify initialization parameter "COMPATIBLE from 11.2.0.0.0 to 10.2.0.3.0" in the "All Initialization Parameters" window.
So, when I finally start installing database, I get following error during the install:
ORA-00201: control file version 11.2.0.0.0 incompatible with ORACLE version 10.2.0.3.0
ORA-00202: control file: '/u01/app/oracle/cfgtoollogs/dbca/infpp1/tempControl.clt'
IGNORE OR ABORT...
Now you might ask why i am doing this. Actually I want to install fresh 11grel2. database with lower compatible parameter. IMPORT DP custom schemas into this database making sure compatible is set to 10.2.0.3.0. Then run database with such settings for a week and finally change compatible parameter to 11.2.0.0.0
Any thoughts where i am going wrong? as the default template seems not accepting what i am interested to do.
I had installed Oracle 11g R1 on windows system where Oracle 10g R2 also installed. As I required both versions parallel on same server, both are installed on different Oracle homes.
Configured listener.ora & tnsnames.ora files on 11g (path) with 10g details also in same file, checked the listener status, its �READY� & windows services also started but now only I am able to connect Oracle 11g & not able to connect Oracle 10g.
how to configure so that I can able to connect both VERSIONS separately on the same server.
I often use "alter session set xxx=xxx;" command to change parameter value temporarily. After that, how to reset parameter value to default and I don't want logout sqlplus.

I'd like to know if it's possible to install a client with Windows 7 (64bits) can be installed with Oracle 11gR2 (32 bits) when the server is still with Oracle 10.1.0.2 ?

Currently we have oracle 10.2.0.4.0 installed on AIX server, can we install oracle 11gR2 on the same server under on user, & both the versions will be in use.
How to manage the profile of the user having 2 oracle versions on AIX & on windows how to handle it.
How to change db timezone parameter. My application team has asked me to change the db timzone parameter by following sql.
ALTER database SET TIME_ZONE = '+10:00';
Is this way is the correct one , and do we have any impact on database and does it require a db bounce.
It always used to be that Automatic Memory Management and Linux huge pages were incompatible: you had to use one or the other. But 11.2.0.2 has new parameter, USE_LARGE_PAGES. This isn't documented apart from a few articles on metalink, but Googling it suggests that if it is on TRUE (the default) or ONLY then I can use AMM with huge pages.

We do not specify any other tablespace information. Not even for temporary tablespace. Then why we need to give undo tablespace name while instance is creating.

I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.
My question is, how more than 500 users can connect to the database without any issue, if we set the value of "sessions" parameter to 500?
quick check on a hidden parameter? I need to know the default value and possible values for _serial_direct_read on various releases, I have only 11.2.0.3 available right now and I'ld like to know this for 11.2.x.x 11.1.x.x, and 10.2.x.x.
Below is the query that will show what it is currently which (unless you've changed it) will be the default: auto for my 11.2.0.3. Then to see the options, try to set it to something wrong, my options are false/true/never/auto/always. I think false/true were the only choices for 10.2 and are maintained only for compatibility. But I can't rememebnr 11.1.

I am getting the following error while starting database.
ORA-32004:obsolete and/or deprecated parameter(s) specified
I have a question about spfile.
SQL> SELECT COUNT(*) FROM v$parameter WHERE value IS NOT NULL;
COUNT(*)

246
SQL> SELECT COUNT(*) FROM v$spparameter WHERE value IS NOT NULL;
COUNT(*)
----------
20
v$parameter displays information about the initialization parameters that are currently in effect for the session,but v$spparameter displays information about the contents of the spfile.I want to know why the count of parameters whose values are not null in v$parameter is greater.where are they from? My initialization parameter file is spfile.
i try to startup a database, and get that obsolete/deprecated parameter specified(ORA-32004: obsolete and/or deprecated parameter(s) specified)so i try to reset the parameter, but it seems it is already reset(not in spfile), so maybe this is in memory. SO now i try to reset with scope = memory or both, it gives this error(ORA-32029: resetting with SCOPE=MEMORY or SCOPE=BOTH is currently not supported).
what to do, because now i cannot reset with scope = memory and in spfile it is not there but still it comes in deprecated parameter.
Database version: 10.2.0.4 Patch 45 on Windows 2003
1. Documentation says to set "_first_spare_parameter" to resolve bug 6904068. What should be the value if we actually see this bug occurring after applying the patch. How can we determine that we need this parameter to be turned on?
2. How can we determine we need to set "_third_spare_parameter"? How can we check if there is a regression on log files?
how to find the versions of exp and imp utilities of database server from windows command prompt?
Note: Currently i have 10.2.0.10 oracle software installed on my local machine.

what are the main points that these examples are considered cursors? and why are they called explicit and implicit cursor.
explicit
for x in (select * from emp) loop
dbms_output.put_line('emp no: '||x.empno);
end loop;
implicit
select empno
into vEmpno
from empno
where empname = 'SCOTT';
for all we know that these are not clearly defined on the declaration area as cursor.
we get daily a full dump from our customer. We have to build the differences of tables (deltas) and load them in separate tables.
There some questions, requiremenst and restrictions:
1) Is it possible the merge the dumps ?
2) How to build the differences as the easiest ?
3) The whole process (import, merge, extract) should be run in batch.
4) We have only a solid knowledge and liitle time for doing.
I am planing to write the web-application which use Oracle DB 11g.I would like to understand what are the differences (specially, performance issues, steps of execution, optimizer possibilities) between calling SQL statements and PL/SQL procedures/functions. Which approach is more appropriate, and why?
Examples:
a) WebApp->Call("select * from employees where department_id = ?", 10) ;
b) WebApp->Call("? := mypackage.get_emp(?)", refCursor, 10);
create package mypackage is
function get_emp(dep_id in number) return sys_refcursor is
begin
open cur for select * from employees where department_id = dep_id;
end;
