This fifth post assumes that you want to add a new node to your cluster and database. It describes most of the associated “silent” syntaxes. Even if you don’t leverage RAC’s ability to add or remove nodes to gain in agility, it’s still very likely you’ll come to these techniques when you want to upgrade some of your Servers or Operating Systems.
This fourth post introduces the fundamental silent installation commands for a 10.2 RAC. this post will dig into how to (1) install the 10.2 Clusterware, (2) apply the latest Patch Set on top of it, (3) install the 10.2 database, (4) apply the latest Patch Set on top of it, and (5) create a RAC database. These operations will be performed with the Oracle Universal Installer, NETCA and DBCA in silent mode. Before you start, just in case you’re not familiar yet with Oracle Silent Installation.
This post is the third of the series of ten posts that explore some of the Oracle Universal Installer (OUI), Network Assistant (NETCA), Database Creation Assistant (DBCA), Database Upgrade Assistant (DBUA) and other syntaxes you can use to script or speed up Oracle Installations. This post will dig into the cloning features of both the Universal Install (OUI) and the Database Configuration Assistant (DBCA)
This post is the second in a series of ten posts exploring some of the Oracle Universal Installer (OUI), Network Assistant (NETCA), Database Creation Assistant (DBCA), Database Upgrade Assistant (DBUA), and many more syntaxes you can use to script or speed up Oracle Installations. This post is way shorter and digs into a couple OPatch, DBUA, and OUI syntaxes. It explains how to apply a one-off patch, how to upgrade a database and how to uninstall a previous ORACLE_HOME.
This post is the first of a series of ten posts that will explore some of the Oracle Universal Installer (OUI), Network Assistant (NETCA), Database Creation Assistant (DBCA), Database Upgrade Assistant (DBUA), and many more syntaxes you can use to script or speed up Oracle Installations. Let’s start with covering the Installation of 10.2 And 11.1 Databases.
RDA 4.11 is out, with a couple of new features. “Oracle Database Diagnostics Collector” (ORADDC) is one of those. It allows you to easily activate all kinds of traces, dumps, or stack collections. This may become one of the most used RDA modules for Oracle Support Services and Oracle database administrators stuck in different situations. For now, let’s start with a more basic question: “How to leverage RDA in a RAC environment ?”
I’m amazed what people are able to do with Oracle technologies. One of the things I’ve liked the most is to spend some time (not enough!) with Kuassi Mensah. The guy is awesome! As a Product Manager at Oracle, he knows probably everything about JServer (the JVM in Oracle 11g), and he is one of the best guys on the subject of some of the key connection layer to access an Oracle database, including JDBC, OCI, and Web Services.
If you’re interested by any of those subjects, you should subscribe to his 360Â° blog and read his book.
What I’ll be doing in the next five days is kind of a secret. Unfortunately, that’s all I’m allowed to tell you, except maybe that I know many people who would love to be in my shoes this week.
ASM is definitely one of the coolest technologies inside the Oracle Database. On the other hand, the ability of the storage arrays to provide a read/write access to a copy or a “snapshot” of its content is something we can easily leverage as an Oracle DBA. For a couple of weeks, I wanted to copy a database stored in an ASM Disk Group with one of those storage technologies and mount it on the same server; unfortunately, this is not supported even with 126.96.36.199. The good news is that I finally overcame all the obstacles to do it in a specific case. This post relates a couple of the tips I used to get to that result.
Recreating the Voting disk may not be as easy as written in Metalink. If you work with RAC, you know about Metalink Note 399482.1 : “How to recreate OCR/Voting disk accidentally deleted”. Of course, you back up the voting disk every time you change your RAC configuration, or on a regular basis. You probably played with the procedure and it worked just fine. Like you, I did all of that. Yesterday, I had to recreate this precious file when it was lost a couple of hours after the whole software stack had been installed. It was, I guess, just before we would have setup our monitoring on the server that would have backed up the voting disk. Here’s how you can fix this problem
