Linux Server pattern fails with identification payload errors due to "UNIX Cluster - ORACLE Clusterware" pattern libraryDescriptionIdentification engine will fail to process Linux Server payload with the following error in the pattern log:2019-12-03 23:51:30: Identifier: Identification CI Errors:Insertion failed with error,Insertion failed with error,Insertion failed with error,Insertion failed with error,Insertion failed with error,Insertion failed with error,Insertion failed with error,Insertion failed with Followed workaround in PRB1384378 as below but still have same error.The workaround was to change the precondition on steps 23 and 26 to the following:Step 23:FROM: $oracle_crs_cluster_resources_ph1 Is Not EmptyTO:$oracle_crs_cluster_vip_resources_ph1 Is Not EmptyStep 26:FROM: $oracle_crs_cluster_resources_ph2 Is Not EmptyTO:$oracle_crs_cluster_vip_resources_ph2 Is Not Empty==============================================1. Debug the pattern based on the error and Cause seems to be with : UNIX Cluster - ORACLE Clusterwarestep : 43.

PATTERN [FILE]...Try 'grep --help' for more information.Steps to Reproduce Run discovery to Linux Server that has Oracle cluster installedWorkaroundWorkaround update set is attached. (Note: one is for Paris and the other is for Orlando, please pick the one that matches your instance) Please import, preview, commit the update set, then in Discovery Patterns, search for "UNIX Cluster - ORACLE Clusterware", open it, then click on related link "Synchronize with MID Servers"Related Problem: PRB1450998
