There’s a unusual command in SQL*Plus that may be useful under certain circumstances: the COPY command (http://docs.oracle.com/cd/E11882_01/server.112/e16604/apb.htm).
Although this command will be obsoleted in future releases of SQL*Plus, Oracle has been saying the same since (at least) Oracle 9, and it’s still available in Oracle 11gR2.
I need to copy a table from one database to another database, and I don’t want to do an export/import of the table.
A simple copy of the table is enough for me:
miquel@db_2> copy from otheruser@db_1 create my_table using select * from other_table; Enter FROM password: Array fetch/bind size is 1000. (arraysize is 1000) Will commit when done. (copycommit is 0) Maximum long size is 2000000000. (long is 2000000000) Table MY_TABLE created. 55481 rows selected from otheruser@db_1. 55481 rows inserted into MY_TABLE. 55481 rows committed into MY TABLE at DEFAULT HOST connection.
It’s that simple!
Feel free to comment below.
Oracle 11g introduces a new security feature: case sensitive passwords.
Case sensitive passwords may cause problems if you run an old version of Oracle Forms (6i in my case) with an Oracle 11g database. The LOGON built-in sends the password to the database un UPPERCASE, so if the passwords doesn’t match, you cannot login to the database.
To disable case sensitive passwords in oracle 11g you have to modify the SEC_CASE_SENSITIVE_LOGON initialization parameter:
SYSTEM@mydb> show parameter SEC_CASE_SENSITIVE_LOGON NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ sec_case_sensitive_logon boolean TRUE SYSTEM@mydb> alter system set sec_case_sensitive_logon=false;
To enable case sensitive passwords again, revert back to true.

I’m getting errors of block corruption in the alert.log of an Oracle 11g Release 2 test database:

In this case it’s not a data corruption, I’ts due to a silly mistake in the creation of a tablespace.
I have two databases created on the same server (it’s a test server), and the datafiles of the two databases in different folders:
- /app/oracle/oradata/database1: datafiles of the database 1.
- /app/oracle/oradata/database2: datafiles of the database 2.
I’m testing an application with different database configurations. So, I created this user in database 1, with its own datafile, but by mistake I created the datafile on /app/oracle/oradata/database2, the folder for the other database’s datafiles.
Then, I did the same for the database 2, created the same user, with its own tablespace, and now, I created the datafile correctly in its own folder (/app/oracle/oradata/database2), with the same name as the other database’s datafile. This is an illustration of this mistake:
When I noticed the error in the alert log, I performed a backup of the user on both databases. Then, dropped the user in database 1 to recreate it again, but when I try to delete the tablespace in database 1 I get this error:
SQL@database1> drop tablespace sgirgea; drop tablespace sgirgea * ERROR at line 1: ORA-01122: database file 42 failed verification check ORA-01110: data file 42: '/app/oracle/oradata/database2/sgirgea_01.dbf' ORA-01210: data file header is media corrupt
Trying to alter the tablespace to bring it offline doesn’t works:
SQL@database1> alter tablespace sgirgea offline; alter tablespace sgirgea offline * ERROR at line 1: ORA-01122: database file 42 failed verification check ORA-01110: data file 42: '/app/oracle/oradata/database2/sgirgea_01.dbf' ORA-01210: data file header is media corrupt
I try to bring the tablespace offline with the database mounted, but I can not shutdown the database for the same reason:
SQL@database1> shutdown immediate; ORA-01122: database file 42 failed verification check ORA-01110: data file 42: '/app/oracle/oradata/database2/sgirgea_01.dbf' ORA-01210: data file header is media corrupt
Prior to a shutdown abort, I tried to offline the datafile, instead of the tablespace:
SQL@database1> alter database datafile 42 offline; alter database datafile 42 offline * ERROR at line 1: ORA-01145: offline immediate disallowed unless media recovery enabled
But it’s not possible because the database is in NOARCHIVELOG mode, as this is a test environment.
Finally, I tried an offline drop of the datafile and it worked. Then just dropped the tablespace just including contents, not the datafile (without the “including contents and datafiles” clause, only “including contents“):
SQL@database1> alter database datafile 42 offline drop; Database altered. SQL@database1> drop tablespace sgirgea including contents; Tablespace dropped.
Then I checked for the datafile and it’s still there, and it’s correctly attached to database2, and everything works fine on database 2. Just have to recreate the same user in database 1 to continue testing.

I’m trying to export a user on a Oracle 11g Relase 2 database (184.108.40.206) using my local client, Oracle 10.2.0.4.
With certain users I’m getting this error:

I tried also not to exporting indexes (indexes=N), as some other blogs suggested, but no luck.
This is due to the different versions of my client export and the database target.
I tried the same export using the 11gR2 client and the export finished without errors.
Thanks to all of you who have read and commented on my (our) blog!

When I’ve finished all the configuration steps, create a database with dbca and I get this error:
$ dbca ORA-21561: OID generation failed
I’ve to assign the correct IP and now the database creation is successful.
I’m configuring a new database on a recently created VMWare virtual server.
When I try to launch netca (or dbca, or whatever else), I get this error:

First of all, I reviewed all my environment variables, then launched xclock to check that my X are well configured, and all that stuff was ok.
The problem is that the filesystem where the oracle binaries were installed were moved to another filesystem by our sysadmins, and the permissions of the entire oracle folder and subfolders were changed to root:root.Simply revert back permissions to oracle:dba solved this silly error.
Never trust on your sysadmins ;-D
First of all, try the installation process specified in the section “Modify the deb package and install again”. This post is the full log of my installation, but I have had to reinstall again following the steps of this section because the system became unstable.
Lets try to install the new Lotus Notes 9 in my fresh installation of Ubuntu 13.04 64 bits.
First of all, a quick view of Usable software backlog blog, a must of every Lotus Notes on Ubuntu user: http://usablesoftware.wordpress.com/2013/03/21/quick-guide-installing-notes-9-on-ubuntu-13-04-beta1-64bit/
I tried to install and I get a lot of dependencies (intentionally suppressed some lines of the output):

Once installed this bunch of packages, I try to install notes with –force-depends option, as suggested Charlie in the comments (I can see unsatisfied dependencies on some essential packages, as grep, see below for details) :
$ sudo dpkg --force-depends -i ibm-notes-9.0.i586.deb S'està preparant per a reemplaçar ibm-notes 9.0-20130309.0942 (emprant ibm-notes-9.0.i586.deb)… S'està desempaquetant el reemplaçament de ibm-notes… dpkg: ibm-notes: problemes de dependències, però es configurarà igualment tal i com heu demanat: ibm-notes depèn de gdb. ibm-notes depèn de grep. ibm-notes depèn de libcupsys2. ibm-notes depèn de libgconf2-4. ibm-notes depèn de libgnome-desktop-2 | libgnome-desktop-2-7 | libgnome-desktop-2-11 | libgnome-desktop-2-17 | libgnome-desktop-3-2. ibm-notes depèn de libpam0g. ibm-notes depèn de libxkbfile1.

S'estan processant els activadors per a desktop-file-utils… S'estan processant els activadors per a gnome-menus…
And it works fine, with no extra karmic libs as with other installations (https://myotragusbalearicus.wordpress.com/2012/01/12/install-lotus-notes-8-5-3-on-ubuntu-11-10-64-bits-with-gnome3/).
When I try to install other packages, I’m getting errors. When I try to fix them, I get this error (slightly different from Usable Software’s blog):

Modify the deb package and install again
For me this has worked. So If you have the same scenario as me (Lotus Notes 9.0 and Ubuntu 13.04 64 bits), it’s preferable to modify the deb package and install with no dependencies (see the Collateral damages section). Maybe you’ll have to install some dependencies if it does not work for you (I already installed it at the begginning of the post, but maybe some of them are unnecessary).
First of all, modify the dependencies of the ibm-notes-9.0.i586.deb package (see http://usablesoftware.wordpress.com/2012/05/04/install-lotus-notes-8-5-3-on-ubuntu-12-04-64bit/ for instructions on unpacking and repacking the deb package):
- Extract the deb file
- Go to DEBIAN folder
- Edit the control file
- Clear the pre-depends and depends lines:
Pre-Depends: libgnomeprint2.2-0, libgnomeprintui2.2-0 Depends: gdb, coreutils, unzip, bash, procps, grep, sed, libart-2.0-2, libasound2, libatk1.0-0, libbonobo2-0, libbonoboui2-0, libc6, libcupsys2, libfontconfig1, libfreetype6, libgcc1, libgconf2-4, libgtk2.0-0, libglib2.0-0, libgnome2-0, libgnomecanvas2-0, libgnome-desktop-2 | libgnome-desktop-2-7 | libgnome-desktop-2-11 | libgnome-desktop-2-17 | libgnome-desktop-3-2, libgnomeui-0, libgnomevfs2-0, libglib2.0-0, libice6, libjpeg62, liborbit2, libpam0g, libpango1.0-0, libpng12-0, libpopt0, libsm6, libstdc++6, libx11-6, libxcursor1, libxext6, libxft2, libxi6, libxkbfile1, libxml2, libxp6, libxrender1, libxss1, libxt6, libxtst6, libz1
Change it for:
- Now go to the root folder again rename the original deb file.
- Generate the deb package again (install the package dpkg-dev if you don’t have the dpkg-deb command) and reinstall it(now you don’t need to force dependencies):
$ dpkg-deb -b ibm-notes-9.0.i586 dpkg-deb: building package `ibm-notes' in `ibm-notes-9.0.i586.deb'. $ chmod +x ibm-notes-9.0.i586.deb $ sudo dpkg -i ibm-notes-9.0.i586.deb Selecting previously unselected package ibm-notes. (Reading database ... 161789 files and directories currently installed.) Unpacking ibm-notes (from ibm-notes-9.0.i586.deb) ... Setting up ibm-notes (9.0-20130309.0942) ... Processing triggers for bamfdaemon ... Rebuilding /usr/share/applications/bamf-2.index... Processing triggers for desktop-file-utils ... Processing triggers for gnome-menus ...
And now you can run Lotus Notes 9 Social Edition:
One of our developers has problems with a select of different tables:
SELECT ROWID, TMP_TABLE_ALIAS.* FROM (select a.*, B.*, (SELECT MAX(TMP_CODEMP) FROM ATE_TABLE WHERE TMP_IDTRE = TRE_ID and TMP_FI is null ) AS TRE_CODEMP, (SELECT MAX(REV_DATA) FROM AR_TABLE WHERE REV_ID = TRE_ID ) AS TRE_DATREV FROM AT_TABLE a, AP_TABLE B WHERE PER_ID = TRE_ID (+) ) TMP_TABLE_ALIAS;
This statement works on the development environment, but in the production environment it fails with:
ORA-01445: cannot select ROWID from, or sample, a join view without a key-preserved table 01445
The database versions is the same in both environments: Oracle 10g Release 2 (10.2.0.5).
After reviewing the tables in the production environment, I noticed that one of the tables has no primary key, and that caused the ORA-01445. Even with a unique index the select fails, it’s mandatory to declare primary keys for the tables when they are involved in joins.
To archive and compress a folder with tar use this command:
$ tar -czvf folder.tar.gz folder
Be careful with the parameters order: tar -czvf is not the same as tar -cvfz. The fist one is ok, but the second one ends with an error:
$ tar -cvfz folder.tar.gz folder tar: folder.tar.gz: Cannot stat: No such file or directory folder/ folder/file1.txt folder/file2.txt folder/file3.txt tar: Exiting with failure status due to previous errors
An ls will show a z file. The reason is that the -f parameter takes the next argument as the filename to archive, thus the z file in our folder. So you have to use the tar -czvf syntax.
