Infrastructure at your Service
As the saying goes, “A Picture Is Worth A Thousands Words”. I’d add “And A Simple Graph Is Worth A Long, Abstruse List of Numbers”. And of words too, so let’s show off a little bit: Interested ?

Hervé already did some tests with zheap and documented his results yesterday. After some more discussions with Amit who did the session about zHeap at the conference here in Lisbon (you can find the slides here).

Introduction It has been 5 years I’m working on ODA and I now have a quite good overview of the pros and the cons of such a solution. On one hand, ODA can greatly streamline your Oracle Database environment if you understand the purpose of this appliance. On the other hand, ODA can be your nightmare if you’re not using it as it supposed to be used. Let’s discover the common mistakes to avoid from…
Foglight is a powerful and all in one monitoring solution to monitor various IT infrastructure assets like databases, servers, applications and so on.

This can fail with OUI-10022 error which indicates that Oracle inventory is corrupt. But when trying an “opatch lsinventory” as oracle and as grid user these commands succeeded, so inventory seems to be ok. It turned out that the locks subdirectory of the oracle inventory was not writable for the grid user. After making…

Introduction X3-2 and X4-2 ODAs are still very capable pieces of hardware in 2018. With 256GB of RAM and at least 16 cores per node, and with 18TB RAW disk capacity as a standard these appliances are far from obsolete even you probably don’t have any more support on the hardware from Oracle. If you own several ODAs of this kind, hardware support may not really be a problem. If something fails, you can use…

If you want to have the details of the sessions go the conference website https://www.postgresql.eu/events/pgconfeu2018/schedule Tour de Data Types: VARCHAR2 or CHAR(255)? Very…
After upgrading the Oracle Access Manager from 11.1.2.3 to 12.2.1.3, I extended the WebLogic Domain with User Messaging Services to be able to use the Forget Password feature. The Oracle Support note ID 2302623.1 gives a good example how to do.

But the OAM AdaptiveAuthenticatorPlugin was missing the UmsClientUrl property and without…

The pack command:cd $FMW_HOME/oracle_common/common/bin ./pack.sh -domain=/u02/config/domains/workshop_domain \ -template=/home/weblogic/workshop/lab_DomainCreation/workshop_template.jar \ -template_name=workshop_template \ -managed=trueThe new created jar file was copied on the remote server and the unpack command run:cd $FMW_HOME/oracle_common/common/bin ./unpack.sh -domain=/u02/config/domains/workshop_domain \ -template=/home/weblogic/workshop/lab_DomainCreation/workshop_template.jarStarting the node manager failed due to the DemoIdentity Java KeyStore file missing. This one was…
