Oracle CPU July 2014 + Oracle Exploit CVE-2013-3751

Alexander Kornbrust - Wed, 2014-07-16 10:03

Yesterday, Oracle released a new critical patch update (CPU Jul 2014) for July 2014. This CPU contains fixes for 5 database vulnerabilities. The most critical one, CVE-2013-3751, has a base score of 9.0 and affects Oracle 12.1 only. The same issue was already fixed for Oracle 11.2 in July 2013 (CPU Jul 2013).

After a short research on the web (google and twitter, less than 5 minutes) I found an exploit for the CVE-2013-3751.

This vulnerability was found by Nicolas Grégoire: He released an exploit nearly 1 year after the patch was published by Oracle. But it seems that he was not aware that Oracle forgot to fix this issue in Oracle 12.1

Timeline of CVE-2013-3751:

  • January 2012: Vulnerability found (fuzzing)
  • February 2012: Vulnerability reported to ZDI
  • March 2012: Vulnerability contracted $500
  • November 2012: Reported to Oracle by ZDI
  • July 2013: Patch published by Oracle
  • March 2014: Oracle’s Cloud still not patched
  • June 2014: Exploit released at INS#14 conference
  • July 2014: Patch for Oracle 12.1 published by Oracle

Coherence Adapter Configuration

Antony Reynolds - Wed, 2014-07-02 23:05
SOA Suite 12c Coherence Adapter

The release of SOA Suite 12c sees the addition of a Coherence Adapter to the list of Technology Adapters that are licensed with the SOA Suite.  In this entry I provide an introduction to configuring the adapter and using the different operations it supports.

The Coherence Adapter provides access to Oracles Coherence Data Grid.  The adapter provides access to the cache capabilities of the grid, it does not currently support the many other features of the grid such as entry processors – more on this at the end of the blog.

Previously if you wanted to use Coherence from within SOA Suite you either used the built in caching capability of OSB or resorted to writing Java code wrapped as a Spring component.  The new adapter significantly simplifies simple cache access operations.

Configuration

When creating a SOA domain the Coherence adapter is shipped with a very basic configuration that you will probably want to enhance to support real requirements.  In this section I look at the configuration required to use Coherence adapter in the real world.

Activate Adapter

The Coherence Adapter is not targeted at the SOA server by default, so this targeting needs to be performed from within the WebLogic console before the adapter can be used.

Create a cache configuration file

The Coherence Adapter provides a default connection factory to connect to an out-of-box Coherence cache and also a cache called adapter-local.  This is helpful as an example but it is good practice to only have a single type of object within a Coherence cache, so we will need more than one.  Without having multiple caches then it is hard to clean out all the objects of a particular type.  Having multiple caches also allows us to specify different properties for each cache.  The following is a sample cache configuration file used in the example.

<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
  <caching-scheme-mapping>
    <cache-mapping>
      <cache-name>TestCache</cache-name>
      <scheme-name>transactional</scheme-name>
    </cache-mapping>
  </caching-scheme-mapping>
  <caching-schemes>
    <transactional-scheme>
      <scheme-name>transactional</scheme-name>
      <service-name>DistributedCache</service-name>
      <autostart>true</autostart>
    </transactional-scheme>
  </caching-schemes>
</cache-config>

This defines a single cache called TestCache.  This is a distributed cache, meaning that the entries in the cache will distributed across the grid.  This enables you to scale the storage capacity of the grid by adding more servers.  Additional caches can be added to this configuration file by adding additional <cache-mapping> elements.

The cache configuration file is reference by the adapter connection factory and so needs to be on a file system accessed by all servers running the Coherence Adapter.  It is not referenced from the composite.

Create a Coherence Adapter Connection Factory

We find the correct cache configuration by using a Coherence Adapter connection factory.  The adapter ships with a few sample connection factories but we will create new one.  To create a new connection factory we do the following:

  1. On the Outbound Connection Pools tab of the Coherence Adapter deployment we select New to create the adapter.
  2. Choose the javax.resource.cci.ConnectionFactory group.
  3. Provide a JNDI name, although you can use any name something along the lines of eis/Coherence/Test is a good practice (EIS tells us this an adapter JNDI, Coherence tells us it is the Coherence Adapter, and then we can identify which adapter configuration we are using).
  4. If requested to create a Plan.xml then make sure that you save it in a location available to all servers.
  5. From the outbound connection pool tab select your new connection factory so that you can configure it from the properties tab.
    • Set the CacheConfigLocation to point to the cache configuration file created in the previous section.
    • Set the ClassLoaderMode to CUSTOM.
    • Set the ServiceName to the name of the service used by your cache in the cache configuration file created in the previous section.
    • Set the WLSExtendProxy to false unless your cache configuration file is using an extend proxy.
    • If you plan on using POJOs (Plain Old Java Objects) with the adapter rather than XML then you need to point the PojoJarFile at the location of a jar file containing your POJOs.
    • Make sure to press enter in each field after entering your data.  Remember to save your changes when done.

You may will need to stop and restart the adapter to get it to recognize the new connection factory.

Operations

To demonstrate the different operations I created a WSDL with the following operations:

  • put – put an object into the cache with a given key value.
  • get – retrieve an object from the cache by key value.
  • remove – delete an object from the cache by key value.
  • list – retrieve all the objects in the cache.
  • listKeys – retrieve all the keys of the objects in the cache.
  • removeAll – remove all the objects from the cache.

I created a composite based on this WSDL that calls a different adapter reference for each operation.  Details on configuring the adapter within a composite are provided in the Configuring the Coherence Adapter section of the documentation.

I used a Mediator to map the input WSDL operations to the individual adapter references.

Schema

The input schema is shown below.

This type of pattern is likely to be used in all XML types stored in a Coherence cache.  The XMLCacheKey element represents the cache key, in this schema it is a string, but could be another primitive type.  The other fields in the cached object are represented by a single XMLCacheContent field, but in a real example you are likely to have multiple fields at this level.  Wrapper elements are provided for lists of elements (XMLCacheEntryList) and lists of cache keys (XMLCacheEntryKeyList).  XMLEmpty is used for operation that don’t require an input.

Put Operation

The put operation takes an XMLCacheEntry as input and passes this straight through to the adapter.  The XMLCacheKey element in the entry is also assigned to the jca.coherence.key property.  This sets the key for the cached entry.  The adapter also supports automatically generating a key, which is useful if you don’t have a convenient field in the cached entity.  The cache key is always returned as the output of this operation.

Get Operation

The get operation takes an XMLCacheKey as input and assigns this to the jca.coherence.key property. This sets the key for the entry to be retrieved.

Remove Operation

The remove operation takes an XMLCacheKey as input and assigns this to the jca.coherence.key property. This sets the key for the entry to be deleted.

RemoveAll Operation

This is similar to the remove operation but instead of using a key as input to the remove operation it uses a filter.  The filter could be overridden by using the jca.coherence.filter property but for this operation it was permanently set in the adapter wizard to be the following query:

key() != ""

This selects all objects whose key is not equal to the empty string.  All objects should have a key so this query should select all objects for deletion.

Note that there appears to be a bug in the return value.  The return value is entry rather than having the expected RemoveResponse element with a Count child element.  Note the documentation states that

When using a filter for a Remove operation, the Coherence Adapter does not report the count of entries affected by the remove operation, regardless of whether the remove operation is successful.

When using a key to remove a specific entry, the Coherence Adapter does report the count, which is always 1 if a Coherence Remove operation is successful.

Although this could be interpreted as meaning an empty part is returned, an empty part is a violation of the WSDL contract.

List Operation

The list operation takes no input and returns the result list returned by the adapter.  The adapter also supports querying using a filter.  This filter is essentially the where clause of a Coherence Query Language statement.  When using XML types as cached entities then only the key() field can be tested, for example using a clause such as:

key() LIKE “Key%1”

This filter would match all entries whose key starts with “Key” and ends with “1”.

ListKeys Operation

The listKeys operation is essentially the same as the list operation except that only the keys are returned rather than the whole object.

Testing

To test the composite I used the new 12c Test Suite wizard to create a number of test suites.  The test suites should be executed in the following order:

  1. CleanupTestSuite has a single test that removes all the entries from the cache used by this composite.
  2. InitTestSuite has 3 tests that insert a single record into the cache.  The returned key is validated against the expected value.
  3. MainTestSuite has 5 tests that list the elements and keys in the cache and retrieve individual inserted elements.  This tests that the items inserted in the previous test are actually in the cache.  It also tests the get, list and listAll operations and makes sure they return the expected results.
  4. RemoveTestSuite has a single test that removes an element from the cache and tests that the count of removed elements is 1.
  5. ValidateRemoveTestSuite is similar to MainTestSuite but verifies that the element removed by the previous test suite has actually been removed.
Use Case

One example of using the Coherence Adapter is to create a shared memory region that allows SOA composites to share information.  An example of this is provided by Lucas Jellema in his blog entry First Steps with the Coherence Adapter to create cross instance state memory.

However there is a problem in creating global variables that can be updated by multiple instances at the same time.  In this case the get and put operations provided by the Coherence adapter support a last write wins model.  This can be avoided in Coherence by using an Entry Processor to update the entry in the cache, but currently entry processors are not supported by the Coherence Adapter.  In this case it is still necessary to use Java to invoke the entry processor.

Sample Code

The sample code I refer to above is available for download and consists of two JDeveloper projects, one with the cache config file and the other with the Coherence composite.

  • CoherenceConfig has the cache config file that must be referenced by the connection factory properties.
  • CoherenceSOA has a composite that supports the WSDL introduced at the start of this blog along with the test cases mentioned at the end of the blog.

The Coherence Adapter is a really exciting new addition to the SOA developers toolkit, hopefully this article will help you make use of it.

Tackling the challange of Provisoning Databases in an agile datacenter

Pankaj Chandiramani - Wed, 2014-05-14 01:03

One of the key task that a DBA performs repeatedly is Provisioning of Databases which also happens to one of the top 10 Database Challenges as per IOUG Survey .

Most of the challenge comes in form of either Lack of Standardization or it being a Long and Error Prone Process . This is where Enterprise Manager 12c can help by making this a standardized process using profiles and lock-downs ; plus have a role and access separation where lead dba can lock certain properties of database (like character-set or Oracle Home location  or SGA etc) and junior DBA's can't change those during provisioning .Below image describes the solution :



In Short :



  • Its Fast

  • Its Easy 

  • And you have complete control over the lifecycle of your dev and production resources.


I actually wanted to show step by step details on how to provision a 11204 RAC using Provisioning feature of DBLM  , but today i saw a great post by MaaZ Anjum that does the same , so i am going to refer you to his blog here :

brew install sqlplus

Dominic Delmolino - Tue, 2014-05-13 18:59

Gee, that didn’t work.

For those of you wondering about the title of this post, I’m referring to the brew package manager for Mac OS — a nice utility for installing Unix-like packages on Mac OS similar to how yum / apt-get can be used on Linux.

I particularly like the way brew uses /usr/local and symlinks for clean installations of software without messing up the standard Mac paths.

Unfortunately, there isn’t a brew “formula” for installing sqlplus and the instant client libraries (and probably never will be due to licensing restrictions), but we can come close using ideas from Oracle ACE Ronald Rood and his blog post Oracle Client 11gR2 (11.2.0.3) for Apple Mac OS X (Intel).

Go there now and read up through “unzipping the files” — after that, return here and we’ll see how to simulate a brew installation.

organize the software

mkdir -p /usr/local/Oracle/product/instantclient/11.2.0.4.0/bin
mkdir -p /usr/local/Oracle/product/instantclient/11.2.0.4.0/lib
mkdir -p /usr/local/Oracle/product/instantclient/11.2.0.4.0/jdbc/lib
mkdir -p /usr/local/Oracle/product/instantclient/11.2.0.4.0/rdbms/jlib
mkdir -p /usr/local/Oracle/product/instantclient/11.2.0.4.0/sqlplus/admin

Change to the instantclient_11_2 directory where the files were extracted, and execute the following commands to place them into our newly created directories:

mv ojdbc* /usr/local/Oracle/product/instantclient/11.2.0.4.0/jdbc/lib/
mv x*.jar /usr/local/Oracle/product/instantclient/11.2.0.4.0/rdbms/jlib/
mv glogin.sql /usr/local/Oracle/product/instantclient/11.2.0.4.0/sqlplus/admin/
mv *dylib* /usr/local/Oracle/product/instantclient/11.2.0.4.0/lib/
mv *README /usr/local/Oracle/product/instantclient/11.2.0.4.0/
mv * /usr/local/Oracle/product/instantclient/11.2.0.4.0/bin/

While these commands place the files where we want them, we’ll need to do a few more things to make them usable. If you’re using brew already, /usr/local/bin will be in your PATH and you won’t need to add it. We’ll mimic what brew does and symlink sqlplus into /usr/local/bin.

cd /usr/local/bin
ln -s ../Oracle/product/instantclient/11.2.0.4.0/bin/sqlplus sqlplus

This will put sqlplus on our path, but we still need to set the environment variables for things like ORACLE_BASE, ORACLE_HOME and the DYLD_LIBRARY_PATH. Ronald sets them manually and then adds them to his .bash_profile, but I wanted to mimic some of the brew packages and have a .sh file to set variables from /usr/local/share.
To do so, I created another directory underneath /usr/local/Oracle to hold my .sh file:

cd /usr/local/Oracle/product/instantclient/11.2.0.4.0
mkdir -p share/instantclient
cd /usr/local/share
ln -s ../Oracle/product/instantclient/11.2.0.4.0/share/instantclient/ instantclient

Now I can create an instantclient.sh file and place it in /usr/local/Oracle/product/instantclient/11.2.0.4.0/share/instantclient/ with the content I want in my environment.

$ cat /usr/local/share/instantclient/instantclient.sh 
export ORACLE_BASE=/usr/local/Oracle
export ORACLE_HOME=$ORACLE_BASE/product/instantclient/11.2.0.4.0
export DYLD_LIBRARY_PATH=$ORACLE_HOME/lib
export TNS_ADMIN=$ORACLE_BASE/admin/network

Once I have this file in place, I can edit my .bash_profile file and add the following line:

source /usr/local/share/instantclient/instantclient.sh

Open up a new Terminal window and voila! A working sqlplus installation that mimics a brew package install!

EMCLI setup

Pankaj Chandiramani - Mon, 2014-04-28 02:15

A quick note on how to install EMCLI which is used for various CLI operations from EM . I was looking to test some Database provisioning automation via EMCLI and thus was looking to setup the same . 


EMCLI Setup
To set up EMCLI on the host, follow these steps:
1.    Download the emcliadvancedkit.jar from the OMS using URL https://<omshost>:<omsport>/em/public_lib_download/emcli/kit/emcliadvancedkit.jar
2.    Set your JAVA_HOME environment variable and ensure that it is part of your PATH. You must be running Java 1.6.0_43 or greater. For example:
o    setenv JAVA_HOME /usr/local/packages/j2sdk
o    setenv PATH $JAVA_HOME/bin:$PATH
3.    You can install the EMCLI with scripting option in any directory either on the same machine on which the OMS is running or on any machine on your network (download the emcliadvancedkit.jar to that machine)
java -jar emcliadvancedkit.jar client -install_dir=<emcli client dir>
4.    Run emcli help sync from the EMCLI Home (the directory where you have installed emcli) for instructions on how to use the "sync" verb to configure the client for a particular OMS.
5.    Navigate to the Setup menu then the Command Line Interface. See the Enterprise Manager Command Line Tools Download page for details on setting EMCLI.

Webcast: Database Cloning in Minutes using Oracle Enterprise Manager 12c Database as a Service Snap Clone

Pankaj Chandiramani - Thu, 2014-04-17 04:02

Since the demands
from the business for IT services is non-stop, creating copies of production
databases in order to develop, test and deploy new applications can be
labor intensive and time consuming. Users may also need to preserve private
copies of the database, so that they can go back to a point prior to when
a change was made in order to diagnose potential issues. Using Snap Clone,
users can create multiple snapshots of the database and “time
travel
” across these snapshots to access data from any point
in time.


Join us for an in-depth
technical webcast and learn how Oracle Cloud Management Pack for Oracle
Database's capability called Snap Clone, can fundamentally improve the
efficiency and agility of administrators and QA Engineers while saving
CAPEX on storage. Benefits include:



  • Agile provisioning
    (~ 2 minutes to provision a 1 TB database)

  • Over 90% storage
    savings

  • Reduced administrative
    overhead from integrated lifecycle management

Something for the future

Dominic Giles - Thu, 2013-07-18 05:46

A nice little feature in Oracle Database 12c is to query patching information via SQL. You can do this from SQLPlus or any other SQL interface jdbc/odbc etc. You can find more details here

http://docs.oracle.com/cd/E16655_01/appdev.121/e17602/d_qopatch.htm#CBHEBGIB

However you won't be surprised to find that the following query doesn't currently return any useful information.

SYS@//oracle12c/orcl > select DBMS_QOPATCH.GET_OPATCH_LIST from dual;
GET_OPATCH_LIST

RAC aware SLOB2 analyze script (Flash DBA)

Jeff Moss - Mon, 2013-07-15 10:02

I’ve been using the very useful scripts from FlashDBA to run SLOB2 on our new system, but unfortunately the analyze one is not RAC aware, so I’ve modified it, in very minor ways, such that it can use an AWR Global report (awrgrpt.sql) as input and still extract the same values that the original does.

I call the script slob2-rac-analyze.sh

Here is an example run – ignore the numbers as they are not representative of anything in particular.

Jonathan Lewis has a nice article covering the different AWR Reports.

I’ve only tested it on the system at work and it seems to work OK – your mileage may vary and I’d be happy to hear comments to the contrary, in relation to the changes I’ve made for use on RAC, but obviously the script is still 99% unchanged, so please contact FlashDBA if there are any generic issues you want to raise.

I’m not a unix shell script guy, but it seems to work…see what you think.

SQL Translator Profiles in Oracle Database 12c

Dominic Giles - Mon, 2013-07-08 10:19

A new feature in Oracle Database 12c is the ability to intercept and translate third party SQL to Oracle syntactically correct SQL  before it is parsed and executed. So you can now intercept SQL from applications using jdbc and odbc that were designed to run against a non Oracle database and potentially run them completely unchanged. The only work necessary is done by the database development/management team. In Oracle Database 12c we also currently support the automatic translation of some databases SQL. Currently this is limited to Sybase but we're working on others. You can find all the details here

http://docs.oracle.com/cd/E16655_01/gateways.121/e22508/sql_transl_arch.htm#DRDAA131

You can also use the frame work against an application that already successfully runs against an Oracle Database. You might want to do this for migration/performance/security reasons. It also gives you an opportunity to try out an important part of the framework "Translation Profiles".

The following SQL demonstrates a simple use case. I'm using the Swingbench Order Entry schema but the sample schema OE would work just as well.

First grant the privilege to the user you want to create the SQL profile on in this case SOE. You need to do this as sys or system

grant create sql translation profile to SOE

Then connect to the user you've just granted the privilege to (SOE) and create a SQL Translation profile.

-- Drop the profile if it already exists
-- exec DBMS_SQL_TRANSLATOR.DROP_PROFILE('ORDERS_APP_PROFILE');

-- Create a Translation Profile

exec dbms_sql_translator.create_profile('ORDERS_APP_PROFILE');

Then add some SQL to be translated. In our simple example we are translating a count against the ORDERS table and translating it to run against the ORDERS_SOUTH table

-- Create a Translation in that profile

BEGIN
    DBMS_SQL_TRANSLATOR.REGISTER_SQL_TRANSLATION(
      profile_name    => 'ORDERS_APP_PROFILE',
      sql_text        => 'select count(*) from orders',
      translated_text => 'select count(*) from orders_south');
END;

At this stage it's worth seeing whats been populated. You can see the SQL via the following views.

select *  FROM USER_SQL_TRANSLATION_PROFILES;

select * from USER_SQL_TRANSLATIONS;

Then test how this changes the execution by creating our new "ORDERS_SOUTH" table

-- Count the rows we get back from orders
select count(*) from orders;

-- Create a new table  orders_south with just ten rows in

create table orders_south as select * from orders where rownum < 11;

Now we've done that enable the sql translation profile we want to use

-- Set the session to use the sql translation profile

alter session set sql_translation_profile = ORDERS_APP_PROFILE

-- For testing make the sqlplus look like a foreign tool

alter session set events = '10601 trace name context forever, level 32';

Now when we re run our query it will use the ORDERS_SOUTH table even though we've explicitly asked for a count against the ORDERS table.


select count(*) from orders;

-- We should just see 10 rows as opposed to hundreds of thousands

And thats a quick example of SQL Translator profiles in Oracle Database 12c
