How to fix timezone issue in RAC Database.

When mismatch between OS time zone and clusterware time zone SYSDATE and  CURRENT_DATE will return different value, because of at the time of clusterware starting lintener started using clusterware time zone.

Solution : 

1. Shutdown clusterware from root user

crsctl stop crs

2. Change the clusterware time $GRID_HOME/crs/install/s_crsconfig__env.txt file using vi editor from root user. Before change take backup of this file.

bash-4.3# cat s_crsconfig_sbldcdb01_env.txt
### This file can be used to modify the NLS_LANG environment variable, which determines the charset to be used for messages.
### For example, a new charset can be configured by setting NLS_LANG=JAPANESE_JAPAN.UTF8
### Do not modify this file except to change NLS_LANG, or under the direction of Oracle Support Services

#TZ=America/New_York
TZ=Asia/Dhaka
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
RT_GRQ=ON
EXTSHM=OFF
TNS_ADMIN=
ORACLE_BASE=

3. Startup the clusterware from root user

crsctl start crs

ORA-12528: TNS:listener: all appropriate instances are blocking new connections.

ORA-12528: TNS:listener: all appropriate instances are blocking new connections.

Cause :  This condition may be temporary, such as at instance startup. In my case instance are in nomount mode and I am trying to connect database through Primary database.

Solution : After adding SID_LIST_LISTENER in listener I have solved this problem.
