The other day we had a discussion with Oracle sales about the question if you can buy an Oracle Database Appliance (ODA) X7-2 HA when you only have 1 socket license Oracle SE. The licensing rules can be interpreted different by some. Disregarding the question why you would buy an […]

0 In this post I will explain how to create your own ACFS file system (on the command line) that you can use to (temporarily) store data. So you have this brand new ODA X6-2M and need to create or migrate some databases to it. Thus you need space to store […]
0 0 ODA X5-2 simplifies and speeds up the creation of a 12c database quite considerably with oakcli. You can take advantage of this command by also using it in the creation of physical standby databases as I discovered when I had to setup Dataguard on as many as 5 production and […]
0 0 One of the great advantages of the Oracle database Appliance HA is the possibility of Virtualization through OracleVM. This virtualization wasn’t possible for the other members of the Oracle Database Appliance. Until now. In the patch 12.1.2.11.0 which has been released recently for the ODA S,M and L, virtualization is […]
0 0 While I prefer a “loosely coupled architecture” for replication between Oracle and SQL Server, sometimes a direct (database) link cannot be avoided. By using DBMS_HS_PASSTHROUGH for data extraction the 2 other ETL processes (transformation and load) can be configured and administered with more flexibility, providing an almost acceptable level of […]
0 0 At a recent customer install, I was faced with configuring Oracle Traffic Director (OTD) 12.2.1.2.0 Webgate with Oracle Access Manager. Deploying Webgate on OD 12c is very well described in the documentation. See A Configuring OAM Agent (WebGate) for Oracle Traffic Director 12.2.1.2 There is however a flaw in the […]
0 0 Recently, while migrating AIX 11gR2 Databases to Oracle Linux 12cR1 on an ODA X5-2, our setup of Sequence Replication by Oracle Golden Gate appeared to be faulty. The target side sequences were not automatically incremented. The problem came to light during the migration of acceptance databases, and under some time […]
0 0 Since the birth of the ODA X6-2 HA, the net usable storage has become more of a challenge when advising a customer as the X5-2 HA had substantial more – but slower – storage. This very short blogpost is just a quick summary / checklist of the net usable storage, […]
0 0 This is how I dump data from an Oracle Database (tested on 8i,9i,10g,11g,12c) to a delimited ascii file: Next to the query and the generated filename the Dump_Delimited function takes another 6 parameters, each one with a default value. Check out the PL/SQL, and BTW… the basics for this code […]
0 0 Oracle dbms_datapump provides a parallel option for exports and imports, but some objects cannot be processed in this mode. In a migration project from AIX 11gR2 to ODA X5-2 ( OL 5.9 ) 12c that included an initial load for Golden Gate, I had to deal with one of those […]
0 0 THREADED_EXECUTION Threaded_Execution is an Oracle Database 12c feature aiming to reduce the number of Oracle processes on LINUX. After setting parameter THREADED_EXECUTION on TRUE and a database bounce, most of the background processes are threads within just 6 Oracle processes, where more than 60 processes existed before the bounce. And […]
0 0 Creating or modifying an Oracle Database user password can be done by using any standard password generator you can find on the WEB. But I wanted a password to comply to “ora12c_strong_verify_function”, and this isn’t as easy to generate as you might expect. Though most generators provide options to include […]
0 0 A while ago I published an article about the ODA X6-2S and X6-2M, the new entry level machines for small business. And since then Oracle introduced the ODA X6-2L and the successor of de ODA X5-2: ODA X6-2 HA. Quite a line of ODA’s. But when to choose what ODA? […]
0 0 I admit, I’m a bit of a fan of the Oracle Database Appliance. And I also admit there are some characteristics of the X5-2 ODA’s which made it sometimes a bit hard to fit in the needs of the customer. I’ll come to that later in this post. With the […]
0 0 In my previous post Network considerations on an ODA X5-2 I described a solution where I created a private network to optimize network performance between the components running on an Oracle Database Appliance. I am talking about a Virtualized setup in this article, and rebuilding the second pair of public […]
0 0 When you buy an Oracle Database Appliance (ODA) X5-2 off the shelve, you will get a machine with four times 10Gb copper Ethernet (bonded into two interfaces) for public communication and two 40Gb InfiniBand (bonded into one interface) for interconnect communication between the two ODA_BASE’s. You would think that should […]
0 0 Oracle introduced the ODA X6-2S and ODA X6-2M. And no, they are not the successor of the quite popular ODA X5-2, which we installed and configured quite a number of times lately. These 2 new machines are the in-between ODA’s, entry level machines for small business. Single node with flash […]
0 0 Since Oracle launched the Oracle Database Appliance a few years ago it has become clear that only the Enterprise Edition is allowed on the machine. But when NOT using the bare metal setup (not the OracleVM) it’s not always quite transparent what kind of licensing requirements is needed and allowed. More […]
