I need to see if the
iFS will work for something . . . will this
really be in beta soon? If so, will I be able
to try it out at that time, or else how long
will it be before anything concrete would
be available?
Thanks for any info,

Where can I get a list of all Oracle products available in the Cloud?

All Oracle Products available in the Cloud can be viewed here
Applications can be accessed under dedicated "Knowledge Zones" where you can have insightful information about the product, how to develop, implement, market and sell the solutions. Also, under "Join the discussion" tab, you can engage with Oracle and follow the discussion on dedicated social media channels.

LOL what a useless doc. Maybe https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=612452503286937&id=1337394.1&_afrWindowMode=0&_adf.ctrl-…
is a bit better, but good luck trying to be Itanium specific.
Edit: Well, so much for trying to paste in an MOS doc link. It's called 10.2.0.5 Patch Set Updates - List of Fixes in each PSU [ID 1337394.1]

Details on TAF support in Oracle AS 10g

Hi experts,
I'm currently writing a Master's Thesis on High Availability of Applications based on Suns JEE platform.
With Oracle being one of the big players in this market I'm going to investigate the features of the Oracle product stack and compare it with other solutions including opensource.
At the moment I'm looking for details on TAF-support in Oracle AS 10g. Lets assume one has installed the latest release of the Oracle 10g database in a RAC configuration on two or more physical nodes to store the applications data. Lets further assume one has set up the latest release of the Oracle AS 10g on different hosts building an AS farm with clustered OC4J-instances. Now one would like to connect a JEE application running within these OC4J-instances to the RAC database.
Therefore one can configure an OC4J datasource to use a service definition supporting network failover and transparent application failover (TAF) specified in the tnsnames.ora on the AS hosts or directly describe the service in the data-sources.xml. To my knowledge only datasources configured to use the OCI client can be used with TAF. Everything right so far?
Now the interesting part. The best what TAF can do is automatically reconnect to the next known database node if its current node is not reachable or fails, and continue processing an open cursor for select so that the application can continue to use its current connection.
If the application is running a database transaction it can only be rolled back and rerun after failover.
In a good old plain Java application one had to implement the OracleOCIFailover interface and register a callback with the db connection in order to receive failover events. Therefore you need to process the query in a different thread.
In a JEE server only the container should be responsible for creating threads, or? How does the Oracle AS support TAF? How can a user application get notice of a failover and react appropriately. Is the behaviour always the same no matter one decides to implement the data access via simple DAOs or entity beans (CMP/BMP)? I assume it is safe to use a connection pool and container will take care of the necessary cleanup jobs, right? Will the complete connection pool be reconstructed or only connections to the failed node?
Does the application server internally use these OCI callbacks and wrap them up into special Exceptions? Is there anything an application programmer has to do in order to make his data access code ready for TAF, especially in case of failover while the db is processing transactional code?
Any insights and/or code snippets would be greatly appreciated!
Ah, one last question. From a HA perspective is it generally a bad idea to put application logic into the database (use CDM RuleFrame and so on) as there is no support in preserving package states or do you think this makes no difference as one has always to repeat everything since the last commit point no matter in which tier the code resides?
During the next days Im going to set up the above environment for testing. A 10.0.2.1 RAC on RHE4 is already up and running fine. AS 10.1.3.0.0 on RHE4 is following today or tomorrow.
Many thanks for all answers!
Regards,
Eric

Hi,
well, I thought I could dig into the OC4J documentation before installing the server. After reading the OC4J Service Guide for 10.1.2 and 10.1.3 I'm a little bit confused.
First I read the 10.1.2 Service Guide and almost everything seemed to be clear. I found a lot of answers to the questions above. I'd like to sum them up. Please correct me if I got something wrong!
- TAF only works on top of OCI driver
- TAF can be used with connection pooling
- OC4J takes care of connection pool cleanup (OC4J and OCI Pool)
These two pools are mentioned. It's not clear to me how they work together. Do one of you know some source where I can get more information about this?
- after a failover all connections in the pool are checked by OC4J and only alive ones will survive
- in case of a failover TAF issues an exception
- the application has to catch this exception and acknowledge with a rollback, after that the transaction can be restarted (this seems to be the responsibility of the applications code, oc4j will not replay something automatically; If I got it right, CMP entity beans will be an exception to this rule - there OC4J will proceed transparently...)
- the application can use OCI callbacks to customize the failover behavior (well I would like to see some source code example here, as I can't imagine how this could look like)
After that I read the 10.1.3 service guide. The section about datasources in conjunction with HA is much shorter. Besides TAF new? mechanism is introduced, namely Fast Connection Failover (FCF). There is not much information about it but references to the JDBC Guide, because FCF is a feature of the implicit JDBC connection cache. Where cache seems to be just another word for pool.
By the way, the example on p. 4-36 looks wrong at first glance. Enabling FCF and setting:
<property name="fastConnectionFailoverEnabled" value="false"/> ???
Seems to be a typo in the docu, or?
I got the impression, that the text is written as if FCF being TAF's successor, without explicitly saying this. Is this right?
So I proceeded reading the JDBC Developer Guide to lean more about FCF. Here is what I learned:
- since 10g available
- FCF is driver independend (you can also use the thin driver)
- prerequisites are implicit connection cache (pool) enabled, ONS must be configured
- in case of a failover the transcation will be rolled back automatically (not by the application); whereas using TAF you have to use a rollback to acknowledge the error
- only one exception ORA-17008 to catch
- application has to obtain a new connection from the cache (pool), where as using TAF the old connection object can be used, and resend the transaction (same as with TAF)
So when to use what? The comparison on p. 27-8 was not very helpful to find an answer to this question.
On p. 28-1 one can read that TAF does not work with the OCI Connection Pool. That's seems to be contradictory to the statement in Service Guide of 10.1.2 that OC4J takes care of both pools (OC4J and OCI). Or has something changed in 10.1.3 in that regard? May be this is because of the changes in Cache or Pool Management?
What is the advantage of using TAF within OC4J in 10g, if there is any?
What about select statements with FCF? You can only read about transactions. I'd assume the application would get the same exception executing a query (ORA-17008) as executing a transaction, right? So TAF should have the advantage of transparently proceeding selects after a failover. Am I right?
I'd love to see more examples and comparisons of TAF and FCF.
Regards,
Eric

TimesTen Cache Connect support for Oracle 11g

The latest 7.0.5 readme mentioned that "Oracle Release 11gR1 is supported with TimesTen Cache Connect to Oracle on Linux x86 32-bit and 64-bit platforms, and on Windows 32-bit."
What about Solaris 10? It looks like on Solaris 10 only Oracle 10gR2 being supported. What is so specific about Oracle 11?
Thank you,
Alex

TimesTen 7.0.5 can be used to cache data from different versions of Oracle database.
The reason why the support for Solaris, AIX, and HP-UX were not at the same time as the Linux platform was because Oracle database 11g was not available on those platforms initially. So TimesTen 7.0.5 was certified to support only the ones available first, and support for other platforms was added as 11g became available on those platforms. It was just timing of the certification, code base is the same.

Is RDAC supported in Oracle Unbreakable Linux kernel 2.6.32-100.0.19.el5?

Dear,
Is RDAC supported in Oracle Unbreakable Linux Kernel 2.6.32-100.0.19.el5?
If supported, please point to the download link.
We require this in order to plan for the OEL 5.5 kernel upgrade to ULK and to connect SUN SAN storage array 6180.
Thanks,
...basha

From what I can gather you will need to compile the driver from source in order to use the RDAC driver with the UEK kernel. Chances are that it won't compile properly under the UEK kernel, which is more up to date than the RHEL kernel.
You will have to start the system from the supplied original RHEL kernel in order to use the binary IBM RDAC driver distribution. The following is available: http://www.lsi.com/sep/Pages/rdac/ds4000.aspx and http://www.lsi.com/sep/Pages/rdac/ds3000.aspx
You may however be able to use Multipath, which is build in also in the UEK kernel. To get the current supported configurations for IBM System Storage it is best to use the interoperability matrices located at http://www-03.ibm.com/systems/storage/product/interop.html. You can use the link to the "System Storage Interoperation Center (SSIC)" to query your specific configuration (http://www-03.ibm.com/systems/support/storage/ssic/interoperability.wss)

Is XMLTYPE not supported in Oracle Lite?

I tried to create a XMLTYPE column in Oracle Lite. I am getting this error.
[POL-5147] this feature is not supported. Is XMLTYPE not supported in oracle lite ?
Can anyone help me understand how to create XMLTYPE column in oracle lite?
Thanks..

Or you could say that they are supported, but sharpening, moire and de-noise are not available (or just set to default), which is actually more Canon's fault. sRAW is a major mess and we're very lucky it's even supported in AP3, finally.

Urgent! Error: ORA-01034 Oracle not available for Oracle10gi

I have used SQL*Plus for a while, but recently when I try to login there is this error message:
Error:
ORA-01034 ORACLE not available
ORA-27101 shared memory realm does not exist
I had search for the solution quite a while. I changed the "sqlnet.ora" from C:\OraHome_1\NETWORK\ADMIN
I changed SQLNET.AUTHENTICATION_SERVICES=NT; to SQLNET.AUTHENTICATION_SERVICES=NONE and then reboot the machine.
The weird thing is that sometimes it works after I reboot the machine, but recently this just doesn't work any more. The SQL*Plus generates the same error message as I wrote above.
It seems like this kind of problem has troubled lots of oracle database users. IS this a bug that exists in the Oracle10gi?
Or does Oracle10gi require to run on certain operating system platform like Windows XP Professional but does not support for Windows XP Home Edition?
Can the Oracle company provide some error solution guide for the public for their own system?
many thanks

No this specific error message is not a result of an Oracle bug to my knowledge.
In my experience it is a simple matter of not using Oracle correctly. Only it is not that simple from a pure end-user perspective as Oracle is not a mickey mouse little filing system that pretends to be a database (like MS Access).
Which makes sense. After all, driving a bicycle does not mean one is able to get on a superbike. And if you respond "what!! why is it a superbike!?" then you need a bicycle in the first place.
The cause of the error you list - the client is making a local IPC dedicated server connection to the Oracle instance. This fails as the dedicated server cannot find the Oracle SGA (shared memory area) to attached to. This is usually the result of
a) the Oracle instance is down (and thus the SGA does not exist)
b) the ORACLE_SID used by the client is incorrect (and thus it attempts to attach to a non-existant SGA)
Reason (a) could be caused by some underlaying issue that results in the Oracle instance shutting down automatically or unintentionally.
As for what Oracle 10G requires operating system wise. There are detailed platform certification matrixes on the Oracle web site. In addition, the INSTALLATION notes of Oracle also specifies what platforms are supported.
You also fail to mention the exact Oracle product you're running. Oracle XE is different than Oracle Standard Edition which is different than Oracle Enterprise Edition.
There is btw a dedicated support forum here for Oracle XE - and this one ain't it.

What jar file contains oracle.ifs.beans and oracle.ifs.clients classes?

I am trying to build some code which needs oracle.ifs.beans and oracle.ifs.clients packages and classes. I have downloaded the following:
OracleAdministrativeClientUtility
OracleApplicationServer
OracleContentManagementSDK
OracleIIOPClientLibrary
OracleJDeveloper
OracleRMIClientSideLibrary
OracleSOA
OracleWebServicesClientLibrary
None of these appears to contain the oracle.ifs packages.

oracle.ifs.beans and oracle.ifs.clients packages are for the Oracle Internet File System. Are the following JAR files available?
repos.jar
adk.jar

Is SQLPlus supported by oracle cloud?

Hi,
I'm creating a database system using SQLPlus which will be stored/connected to the cloud. I've been made aware that SQLPlus is not supported by Oracle Cloud and that I should use SQL Developer, is this true or will SQLPlus be supported by Oracle Cloud?

The Oracle Cloud is a broad term, but the Oracle Database Cloud Service does not support SQL*Net connections, which rules out SQL*Plus. There are much easier ways to create database objects with the Database Cloud Service,including SQL Developer and SQL Workshop in Application Express. Both of these tools will also run SQL scripts, which is how SQL*Plus works, if you would prefer that.
The upcoming DBaaS offering will include a dedicated database instance in a virtual machine, but that is not slated to be available for a while.
Hope this helps.

Oracle Drive Availability

I may be WAY behind the curve on this but, has Oracle stopped making Oracle Drive available? It seems practically impossible to find now and I can't find it at all on an Oracle site.

I don't see it on Oracle's site either but if you have access to My Oracle Support, check out *Oracle Drive Certification Matrix [ID 387959.1]*. Looks like you could download it from that page.

Oracle MIBs available for compiling?

Are the Oracle MIBs available somewhere so I can download
and compile them into my management system? I'm able to
see a chart of many of them in the SNMP Support Reference
Guide, but that doesn't help my NMS when it performs a walk
and we want to easy understand the output.
Thanks!
