1 PREFACE RAC Attack is an Oracle RAC SIG community effort to invite all Oracle Users to install and configure a 2-‐Node RAC environment on their own hardware (laptops) with experienced RAC Attack Ninja’s support. The effort has gained much support within the last year of its inception and is held at most major conferences. For more information, visit http://racattack.org/12c.

2 PURPOSE The purpose of this particular is to illustrate a conversion from standard to flex for both Cluster and ASM. Although the names Flex Cluster and Flex ASM appear similar, they are two distinct and for the most part mutually exclusive, components of RAC in 12c.

2.1 FLEX CLUSTERS

Fig 1: Flex Cluster Illustration Flex Clusters introduces (among many other new features) the concept of Hub and Leaf nodes.

2.1.1 HUB NODES Hub Nodes are similar to Oracle Grid Infrastructure nodes in an Oracle Clusterware standard Cluster configuration.

2.1.2 LEAF NODES Leaf Nodes are different from standard Oracle Grid Infrastructure nodes, in that they do not require direct access to shared storage, but instead request data through Hub Nodes.

Fig 2: Leaf and Hub Nodes in Flex Cluster Leaf nodes were designed to contain application (non-‐database) components of a system. For example, one could place Fusion Middleware, EBS, IDM etc on a set of leaf nodes, where as on the hub nodes the actual databases for the application would reside. For a standard cluster to covert to a Flex Clusters, Flex ASM must be enabled.

2.2 FLEX ASM Oracle Flex ASM enables Oracle ASM instances to run on a separate physical server from the database servers. An Oracle ASM instance can operate in several configurations in Oracle Flex ASM. The aim of Flex ASM is to consolidate ASM instances into a set of nodes within a cluster.

3 ASSUMPTIONS This lab assumes that the user has an existing 2-‐node RAC environment configured as per the base RAC Attack 12c manual instructions listed here.

4 CONVERT TO FLEX ASM

4.1 GET CLUSTER MODE [oracle@collabn1 ~]$ crsctl get cluster mode status Cluster is running in "standard" mode

4.2 GET ASM CLUSTER MODE [oracle@collabn1 ~]$ asmcmd showclustermode ASM cluster : Flex mode disabled [oracle@collabn1 ~]$ srvctl status asm -‐detail ASM is running on collabn2,collabn1 ASM is enabled. [oracle@collabn1 ~]$ srvctl config asm ASM home: /u01/app/12.1.0/grid



Page#: 6

Password file: +DATA/orapwASM ASM listener: LISTENER [oracle@collabn1 ~]$ asm To convert to Flex ASM, according to Oracle’s documentation, ideally there should be a third (private) NIC attached to all nodes in a cluster. However, if that is not feasible or available, the existing Private Cluster Intereconnect NIC could be utilizes instead.

4.2.1 VIA ASMCA GUI Start the ASM Configuration Assistant. [oracle@collabn1 ~]$ . oraenv ORACLE_SID = [oracle] ? +ASM1 The Oracle base remains unchanged with value /u01/app/oracle [oracle@collabn1 ~]$ asmca

Select the “ASM Instances” tab, and at the very bottom is the option to “Convert to Flex ASM”.



Page#: 7

On the next screen, and for the purpose of this lab, we will select the default listener for ASM network traffic, and the private interconnect as the NIC. Click “OK” to continue.



Page#: 8

Click “Yes” to continue.



Page#: 9

At this prompt, you are requested to run the converttoFlexASM.sh script manually as a privileged user.

4.2.2 VIA ASMCA SILENT MODE [oracle@collabn1 ~]$ asmca –silent convertToFlexASM –asmNetworks eth1, interface_name/172.16.100.0 –asmListenerPort 1521

4.2.3 RUN SCRIPT AS ROOT The script needs to be executed as privileged (root) user on each node.

5 CONVERT TO FLEX CLUSTER Flex Cluster is the next generation of clustware release with version 12c. It introduces the concept of Hub and Leaf nodes where hub nodes have direct access to storage and leaf nodes may or may not. The basic idea is to extend the “standard” cluster and encompass application servers as well. One could run all databases on the hub nodes, and all applications on leaf nodes. There are a few pre-‐requisites to enabling Flex Clusters.

1. Grid Naming Services VIP must be available. 2. Flex ASM must be enabled.

In the context of this lab, we need to additionally perform the steps below:

1. Add a new DNS entry for the GNS Host Name 2. Install and Enable DHCP Daemon

5.3 CONVERT CLUSTER At this point, the cluster can be easily converted to flex mode. All commands must be run as the root user. [root@collabn1 ~]# /u01/app/12.1.0/grid/bin/crsctl set cluster mode flex Cluster mode set to "flex"



Page#: 19

Cluster Ready Services (CRS) must be restarted on both nodes (one at a time) for the change to take affect. [root@collabn1 ~]# /u01/app/12.1.0/grid/bin/crsctl stop crs [root@collabn1 ~]# /u01/app/12.1.0/grid/bin/crsctl start crs -‐ wait [root@collabn2 ~]# /u01/app/12.1.0/grid/bin/crsctl stop crs [root@collabn2 ~]# /u01/app/12.1.0/grid/bin/crsctl start crs -‐ wait Check the cluster mode. [oracle@collabn1 ~]$ crsctl get cluster mode status Cluster is running in "flex" mode
