Return time, format as: 2012-09-23 06:48:28 Curdate, returns the date of the time, formatted as: 2012-09-23 Curtime, return time, format such as: 06:48:28 Unix_timestamp, returns the time integer stamp, such as: 1348408108 Sysdate, the return time, the format and time () function return times, but there are differences. In addition t

A customer reported that in RAC of 11.2.0.3, it is correct to query the time returned by sysdate when using sqlplus to connect.

A customer reported that in RAC of 11.2.0.3, it is correct to query the time returned

Recently, there have been issues with access to sysdate return error times in some RAC environments, which often occur when database links are created through listener, and in most cases are related to time zone settings. In this article we will explain how to diagnose this problem. This article applies to version 11.2.0.2 and above. First, introduce the knowledge involved in the problem. 1.
