Assume that all the WebLogic instance log files are collected into common directory structure, each of them are stored respective instance named folder. Script 1: After identifying the impacted instances, I need to take the heap dump of that particular instance with corresponding process id. #============================================================== # File Name : CheckLogs.sh # Author : Pavan Devarakonda # Purpose : Script for searching all WebLogic in...
