Time Zone Support in Oracle E-Business Suite Cloud Manager

Time Zone Support in Oracle E-Business Suite Cloud Manager

When using Advanced Provisioning to provision an environment, or when creating a standby environment, you are prompted for the operating system time zone you want to use for your instance. This appendix describes how default values for the operating system time zone are derived, as well as the implications of overriding the default values.

When taking a backup of an on-premises environment, you will be prompted for the operating system time zone that you wish to use when restoring the backup in Oracle Cloud Infrastructure. This value will be saved as backup metadata in a property called SRC_OS_TIMEZONE.

When provisioning a new environment from a backup, the default value for the operating system time zone is derived based on the following logic:

The following table illustrates some examples of scenarios with the default value for the field Operating system time zone as well as the time zone to be set in Oracle E-Business Suite Cloud Manager.

In these examples, the user has chosen not to bypass the Server Timezone profile validation.

In this table, the property SRC_OS_TIMEZONE is taken from the backup's metadata. The Oracle E-Business Suite profile option Server Timezone is referred to by its code, SERVER_TIMEZONE_ID.

Table B-1 Examples of Time Zone Values for Advanced Provisioning
Backup Metadata Default Value Shown in UI User-Selected Value Time Zone to be set on Compute-VM Time Zone to be set on VMDB Exadata Infrastructure Time Zone Time Zone Variable (TZ) to be set on the Exadata Cloud Service
SRC_OS_TIMEZONE = NOVALUE
Profile option SERVER_TIMEZONE_ID = NOVALUE
UTC America/New_York America/New_York America/New_York Europe/London Time zone is America/New_York
SRC_OS_TIMEZONE = Asia/Kolkata
Profile option SERVER_TIMEZONE_ID = NOVALUE
Asia/Kolkata Asia/Kolkata Asia/Kolkata Asia/Kolkata Europe/London Time zone is Asia/Kolkata
SRC_OS_TIMEZONE = NOVALUE
Profile option SERVER_TIMEZONE_ID = (GMT+05:30) India Time
IST IST IST IST Europe/London Time zone is IST
SRC_OS_TIMEZONE = IST
Profile option SERVER_TIMEZONE_ID = (GMT - 5) Eastern Time
America/New_York America/New_York America/New_York America/New_York Europe/London Time zone is America/New_York

Note the following:

In the case of environments on an Exadata Cloud Service, where there is one system with many databases on it, Cloud Manager can't use the operating system time zone for a given environment, but instead uses the time zone defined in the Exadata Cloud Service infrastructure.

Alternatively, you might choose to bypass the Server Timezone profile validation.

In the examples in the following table, the user has chosen to override the default value for the time zone, and has chosen to bypass the validation.

Table B-2 Examples of Time Zone Values Bypassing Server Time Zone Profile Validation
Backup Metadata Default Value Shown in UI User-Selected Value Time Zone to be set on Compute-VM Time Zone to be set on VMDB Exadata Cloud Service Infrastructure Time Zone Time Zone Variable to be set on the Exadata Cloud Service
SRC_OS_TIMEZONE = Asia/Kolkata
Profile option SERVER_TIMEZONE_ID = NOVALUE
Asia/Kolkata America/Los_Angeles (Override) America/Los_Angeles America/Los_Angeles Europe/London Not Set
SRC_OS_TIMEZONE = NOVALUE
Profile option SERVER_TIMEZONE_ID = (GMT+05:30) India Time
Asia/Kolkata America/Los_Angeles (Override) America/Los_Angeles America/Los_Angeles Europe/London Not Set
SRC_OS_TIMEZONE = America/New_York
Profile option SERVER_TIMEZONE_ID = (GMT+05:30) India Time
Asia/Kolkata America/Los_Angeles (Override) America/Los_Angeles America/Los_Angeles Europe/London Not Set

In the case of environments on an Exadata Cloud Service, where there is one system with many databases on it, Oracle E-Business Suite Cloud Manager cannot use the operating system time zone for a given environment, but instead uses the time zone defined in the Exadata Cloud Service infrastructure. The time zone variable is not set.

In the case of creating a standby environment from an on-premises environment, the default value will be derived based on the Oracle E-Business Suite profile option Server Timezone (code SERVER_TIMEZONE_ID), if it exists. Otherwise, 'UTC' will be used.
