1. Stop RSA Identity Governance & Lifecycle and the Oracle services:

acm stop
acm stoporacle

2. Switch to the root user and set the correct time zone. This step may be skipped if the configured timezone is correct. 

1. Check the contents of /etc/localtime to verify if the timezone is already correct. If it is, then skip to Step 3.

zdump /etc/localtime

2. Backup the currently configured timezone:

su - 
cp /etc/localtime /etc/localtime.backup_<date>

3. Find your correct timezone in /usr/share/zoneinfo. An example would be /usr/share/zoneinfo/US/Eastern.
4. Replace the currently configured timezone with the correct one.  

cp <new_timezone> /etc/localtime

cp /usr/share/zoneinfo/US/Eastern /etc/localtime

If /etc/localtime is a symbolic link:

1. Check the link to verify if the timezone is already correct. If it is, then skip to Step 3.

# ll /etc/localtime
/etc/localtime -> /usr/share/zoneinfo/<timezone>

# ll /etc/localtime
/etc/localtime -> /usr/share/zoneinfo/US/Eastern

2. Backup the symbolic link:

tar -cvf localtime_backup<date>.tar /etc/localtime

3. Find your correct timezone in /usr/share/zoneinfo. An example would be /usr/share/zoneinfo/US/Eastern.
4. Modify the symbolic link to point to the new timezone.

ln -sfn /usr/share/zoneinfo/<new_timezone> localtime

ln -sfn /usr/share/zoneinfo/US/Eastern localtime

3. Set the correct date and time. The command should look like this.

date -s "DD MMM YYYY HH:MM:SS"

4. Sync the BIOS hardware clock.

hwclock -w

5. Switch to the oracle user, then start Oracle services.

su - oracle
acm startoracle

6.  Login to the database as SYSDBA to clear any database cache issues related to time:

SQLPLUS / as SYSDBA
SQL> STARTUP FORCE;

7. Start RSA Identity Governance & Lifecycle 

acm start
