8. Copyright © 2014, Oracle and/or its affiliates. All rights reserved. For Upgrades Follow the OCR •  CreaBng a new disk group (DG) for the GIMR works for fresh installs. •  When upgrading, the GIMR is placed in the same DG as the OCR in 12.1.0.2 – If OCR mirrors are used, the first locaBon in the list will be used. – For future versions the following rules apply: •  If a GIMR is present (12c or later), then the new GIMR is placed in the same DG as the current GIMR •  If no GIMR is present, the new GIMR is placed in the same DG as the VoBng Disk(s) (ER 19661882) •  In order to define the GIMR DG locaBon during upgrades – locate “the OCR” in the respecBve DG using ocrconfig (online), then upgrade and finally relocate the OCR back to its original locaBon, if required. 9

30. Copyright © 2014, Oracle and/or its affiliates. All rights reserved. Extended Oracle RAC – use Standard Cluster + Flex ASM •  What are “ASM_PREFERRED_READ_FAILURE_GROUPS”? –  The ASM_PREFERRED_READ_FAILURE_GROUPS ini2aliza2on parameter is a comma-‐delimited list of strings that specifies the failure groups that should be preferen2ally read by the given instance. This parameter is generally used only for clustered ASM instances and its value can be different on different nodes. •  Example: “diskgroup_name1.failure_group_name1, ...” –  For extended RAC, this paper: Oracle Real ApplicaBon Clusters on Extended Distance Clusters (p. 26) suggests using the “ASM_PREFERRED_READ_FAILURE_GROUPS parameter to go to the local mirror instead of going to any available mirror.” •  What is the issue? –  Using Flex ASM, by default only three ASM instances are started in the cluster. –  Assuming that the Extended RAC uses more than three nodes (e.g. 2 nodes in each side), there is a likeliness for a cross-‐side failover. •  An ASM instance cross-‐side failover breaks the logic to use “local mirrors” in this case, as the local mirror is side-‐dependent. •  SoluBon: –  Follow the recommendaBon to use “srvctl modify asm –count all” for Extended Oracle RAC implementaBons when using Flex ASM. •  This reduces the staBsBcal likeliness for a cross-‐side failover. –  For future releases, ER / BUG 17045279 – “ASM_PREFERRED_READ DOES NOT WORK WITH FLEX ASM” addresses this problem. 31 How to make use of “ASM_PREFERRED_READ_FAILURE_GROUPS”?
