Hi, I have 15+ yrs of experience in IT industry majorly as Oracle DBA. I have worked in diverse work environments and hybrid domains. I understand the severity of an issue especially in HA production databases very well and act accordingly. I have worked for many customers in various domains. I have written this blog based on my experiences during work, the knowledge I gained through various sources including internet and consolidated all into articles. The solutions I have described is only my experience and these may not be applicable to all cases or environments. This blog is for technology awareness and knowledge gaining purposes only. Contacting Oracle support is always the best way to resolve your Oracle DB issues.
