Server Administration :: Oracle Export Import Utility Different Versions?
May 10, 2012
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?
Is it possible to import a dump file using impdp data pump utility on oracle 10g where the export dump was taken using traditional exp utility and vice versa.
I have a From which take Logical Backup through oracle export utility. This Form work fine when i Start OCJ4 but when i want to take backup after running oracle Forms & Report services its not take backup.
My Question is dose Oracle Forms & Report Services (Standalone) Support data backup through Export (exp) utility. I have install Oracle Forms and Report Services (Standalone) on Window XP (SP-3).
I have problem/misunderstanding with gather schema stat utility of oracle. Herewith i'm posting my try and output of it. My main question is why the column 'LAST_ANALYZED' of dba_tables not updated on gathering fresh schema level statistics.
SQL>select OWNER,TABLE_NAME,NUM_ROWS,AVG_ROW_LEN,BLOCKS,SAMPLE_SIZE,LAST_ANALYZED from dba_tables where owner='STO' and rownum<=10 order by LAST_ANALYZED; OWNER TABLE_NAME NUM_ROWS AVG_ROW_LEN BLOCKS SAMPLE_SIZE LAST_ANAL
SQL> select OWNER,TABLE_NAME,NUM_ROWS,AVG_ROW_LEN,BLOCKS,SAMPLE_SIZE,LAST_ANALYZED from dba_tables where owner='STO' and rownum<=10 order by LAST_ANALYZED;
I am trying to restore a package only from a dump file that was exported by original exp command. I know you can do it with data pump, but unfortunately this is dump file is not exported by expdp. Can I do that. I really do not want to import the whole database.
I would like to run a daily job that will export the table data from SQL server table and Import back into Oracle table. I might need to run the query to update the flag back into sql server table once job is done. How can i do this using either sql server or oracle?
We have oracle 9.2 and sql server 2005.
Normally i do from flat file or csv file which is generated by developer or user from source destination (not me) and i dump into oracle using sql*loader but this time I have to directly extract/export the data from MS Sql server and load into Oracle table, mostly it will reload so i might doing any massaging data during the load.
Is it sql sql*loader has any function that i can use the datasource to connect the MS Sql server and fetch the data and insert back data into oracle? I have access to Sql server but i don't how to use sql server to do this or using oracle as a daily job even because have to schedule the job for this as it will be a daily job.
I have installed Oracle server and SQL Server on separate machines which cause me a time delay of 21 seconds for each execution. Why executions delay? I have set RPC out (true).
Note: My main concern is either if the query is correct/incorrect it executes for 21 seconds._
Another case when I have both servers on the same machine it executes in milliseconds. I have tried Following methods in SQL SERVER.
*1, Using OPENQUERY:* SELECT * From OPENQUERY(Linked Server Name,’Select * from OracleTableName ‘)
*2, Using Exec:* DECLARE @sql NVARCHAR(MAX); SET @sql =(’Select * from OracleTableName ‘); EXEC (@sql) AT Linked Server Name ;
How to reduce the time delay caused for the execution?
I will have to proceed with Oracle 9 database refresh from production server to integration server. 5 biggest schemas must be exported and imported. They constitute 97% space used in a database. This is very big database so I would like to be sure that everything will go smoothly. That is why i want to ask you some questions.
Have you got any clues for me before I start with exp/imp? From my side i will tell you that I will have to exp/imp schema by schema because there is small space both on production and integration disk for a dump. First thing I thought are dependencies between schemas that are exported and that which are not, and also between schemas that are exported/imported one by one.
This is procedure that I plan:
For every schema that is to be refreshed { 1. Export schema with ROWS=N CONSTRAINTS=Y 2. EXPORT schema with ROWS=y CONSTRAINTS=N 3. Import schema from step one 4. Disable all the foreign key constraints using ALTER TABLE DISABLE CONSTRAINT. 5. Import schema with rows } ALTER TABLE ENABLE CONSTRAINT
With above procedure i think that I will avoid problems with dependencies between schemas exported/imported one by one. But my concern is if there are any dependencies between those schemas and schemas that are not exported. Is there an way to check it before refresh ?
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.
In oracle 11g R2 , I face a problem when I export/import xml records in the tables . Everytime it takes huge time (like 2 or 3 days) to import or export the data . But the dump size is very small (4gb) and this dump comes from a vendor so that I dont understand that is it a data structure problem or it the normal behaviour to import xml records.
I am not used to with xml record with oracle database before. Here I am using datapump feature . I also mention that when I delete the schema (where I imported the xml data) , it also takes 2/3 days to delete.The import script will hang in the following stage :

I am new to Oracle DBA. m facing one problem. i imported and exported my data from one oracle DB to another by using exp/imp.....in both exp/imp log files, its shows the fallowing messages at the end.
"Import terminated successfully with warnings." "Export terminated successfully with warnings."
but when i count there are some rows missing in some tables...
what could be the cause? is there any other way to cross check whether export/import was successful...
I would like to Import data from Oracle 10g using Microsoft Sql Server (2008 R2) Import/Export Wizard, but i get this error when i try too establish the connection :
ora-01017
this the step i followed;
1- i filled the server name 2- username & password 3 - test connection ---> success
but when i try to follow pressing next(Suivant) i got the ora-01017 Error
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'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 ?
Can i have 2 versions of oracle database installed on same server under one user on AIX also on windows,
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.
I am trying to export selective data from one of my prod database tables. But not succeeding. I was keep on trying for the past 2 hours.
OS : SOLARIS SPARC ORACLE - 10G Query --> WHERE E3RECV_DT LIKE '201305%' (I need to export this query data)
Below Script i am using =============== exp E3USER@SGEBAPU2 statistics=none consistent=n buffer=100000000 file=exp_pipe_file TABLES=IFDATA query="WHERE E3RECV_DT LIKE '201305\%'" log=PGTB_IFDATA_conditional.log
Why do export-import require temporary tablespace? Since export-import do behave like DMLs, when does temporary tablespace be needed by datapump utility?
I was asked to do export/import of some schemas from 10g(linux) to 11g(AIX) using original expor/import method. I did not consider the character set and started doing export and import. while exporting, I get questionable statistics error in export log file. In the import log, I see the error like CREATE DATABASE LINK "xxxxxxxxxxxxx" CONNECT TO "xxxx" IDENTIFIED BY...
how can i monitor the export and import job and how increase the export and import job performance.
can i monitor the export and import job by checking the log and dump file created by export and import and can its performance increase by configure parallism. m i right or not?
We are doing daily cold backup. Due to lack of disk space,we couldn't Hot backup. We want our database to be up when doing backups. Since only export/import is possible in our scenario, clarify few queries:
1) Export was done during off period from the live server. 2) We have a development server, in which we have to update our database daily. Can i overwrite the Development server using IMPORT daily? Since this import might show lots of errors (Object already exist), what parameters can i use for import.
