During a silent Oracle 12c Release 1 database installation on a newly set up Oracle Enterprise Linux box, I encountered the following error when performing the installation:

[oracle@pandora database]$ ./runInstaller -silent -responseFile /home/oracle/database/response/kdb.rsp 
Starting Oracle Universal Installer...

A log of this session is currently saved as: [..]

But when I checked the hostname, everything seems to be just fine, I even get the FQDN:

Alright, it seems that as of yesterday evening, Oracle 12c Release 1 is available for download for the Linux x86-64 platform!

Now excuse me, I’m off to test out the new release…

After quite a long time, Tanuki Software released another two versions of the Tanuki Service Wrapper. I hereby provide a build of the latest version of the wrapper, version 3.5.19.

As always, I don’t guarantee anything, so please note:

So I get many visits for my post on Oracle Full Datapump Export Batch, so here is the same export script for UNIX systems.

Before using this script, please read my advice:

Ok, so here is a problem that a developer brought up. I thought that this problem is quite interesting and also a bit confusing. Obviously, according to Oracle, this is not a bug – it’s a feature!

When issuing a CREATE MATERIALIZED VIEW statement for a different schema (as DBA), one might encounter the following error:

dba@KDB01:SQL> CREATE MATERIALIZED VIEW simon.simon_mv AS SELECT * FROM dual;
CREATE MATERIALIZED VIEW simon.simon_mv AS SELECT * FROM dual
                                                         *
ERROR at line 1:
ORA-01031: insufficient privileges

For our setup let’s assume we have two users:

When you install the InstantClient binaries, you often want to use your existing TNSNAMES.ORA file containing all your databases. So how do you specify the location of your TNSNAMES.ORA file?

The Oracle website has the answer:

Whenever one has to move large amounts of data from one database to another, storage space might become an issue. An option to circumvent this problem is to use a database link with Oracle Datapump to move the data from one database to another. This way, the data is exported across the network and imported directly into the target database.

In this post, I will provide an example on how to move data via a Oracle Datapump and a database link. This post is based on the excellent entry in Oracle FAQ and basically comments all the steps mentioned in the article.

In another post, a commenter asked how to resolve the “Windows Server: The terminal server has exceeded the maximum number of allowed connections” error when connecting from a Mac.

So here is another post I keep mainly for my own reference, since I regularly need to gather new schema statistics. The information here is based on the Oracle documentation for DBMS_STATS, where all the information is available.

So if you want to COMPUTE the statistics (which means to actually consider every row and not just estimate the statistics), use the following syntax:

So here is another post I keep for my own reference, since I keep forgetting about precision and scale, primarily which is which.

The Oracle Concepts guide states that the NUMBER datatype stores fixed and floating-point numbers. A column with the NUMBER datatype can be defined as follows:
