In some application environments, it is important that application
server components use the same time zone. You can use the administrative console
to ensure that your application components use the correct time zone.
Before you begin
Determine the scope at which you want to set the
time zone value. You can set the time zone value such that is applies for
an entire cell, for an entire node, or only for a specific server.
Remember
that time zone IDs should include an offset and, in almost all cases, a daylight
saving time zone name for consistent results. For example, specify EST5EDT
for Eastern Standard Time, Daylight Savings Time.
About this task
You can specify the Unix System Services (USS)
TZ variable as a WebSphere® variable to change your time zone setting.
To change the time zone setting for a single
application server:
Complete one or more of the following actions to
set appropriate time zone values for your environment.
Procedure
- Set the time zone for all of your server processes.
- In the administrative console, click .
- Select All scopes from the list of scope
options.
- Set a value for the TZ variable.
If the TZ variable
is included in the list of defined variables, click TZ,
and then specify a new time zone value in the Variable field.
If
the TZ variable is not included in the list of defined variables, click New,
and then specify TZ in the Name field,
and the appropriate time zone value in the Value field.
For
example, if you specify TZ in the Name field,
and EST5EDT in the Value field,
Eastern Daylight Savings is used as the time zone setting for all of your
server processes.
- Set the time zone for all of the server processes
in a particular cell.
- In the administrative console, click \ .
- Select the cell for which you want to set the time zone value
from the list of scope options.
- Set a value for the TZ variable.
If the TZ variable
is included in the list of defined variables, click TZ,
and specify a new time zone value in the Value field.
If
the TZ variable is not included in the list of defined variables, click New,
and then specify TZ in the Name field,
and the appropriate time zone value in the Value field.
For
example, if you specify TZ in the Name field,
and EST5EDT in the Value field,
Eastern Daylight Savings is used as the time zone setting for all of your
server processes that are running in that cell.
- Set the time zone for all of the server processes
in a particular node.
- In the administrative console, click \ .
- Select the node for which you want to set the time zone value
from the list of scope options.
- Set a value for the TZ variable.
If the TZ variable
is not included in the list of defined variables, click New,
and then specify TZ in the Name field,
and the appropriate time zone value in the Value field.
If
the TZ variable is included in the list of defined variables, click TZ,
and specify a new time zone value in the Value field.
For
example, if you specify TZ in the Name field,
and EST5EDT in the Value field,
Eastern Daylight Savings is used as the time zone setting for all of your
server processes that are running in that node.
- Set the time zone for a specific server.
- In the administrative console, click \ .
- Select the server for which you want to set the time zone value
from the list of scope options.
- Set a value for the TZ variable.
If the TZ variable
is included in the list of defined variables, click TZ,
and then specify a new time zone value in the Value field.
If
the TZ variable is not included in the list of defined variables, click New,
and then specify TZ in the Name field,
and the appropriate time zone value in the Value field.
For
example, if you specify TZ in the Name field,
and EST5EDT in the Value field,
Eastern Daylight Savings is used as the time zone setting for all of your
server processes.
- Set the time zone value for trace statements in
SYSPRINT for a particular server or for the deployment manager.
- In the administrative console, click
either System administration > Deployment manager, and then under Server
Infrastructure, click > Administration > Custom Properties, or Application
servers > server_name > Server infrastructure > Administration > Custom
Properties.
- Set a value for the ras_time_local variable.
If
the ras_time_local variable is included in the list of defined variables,
click ras_time_local , and then specify 1 in
the Value field.
If the ras_time_local variable
is not included in the list of defined variables, click New,
and then specify ras_time_local in the Name field,
and 1 in the Value field.
For
example, if you specify ras_time_local in the Name field,
and EST5EDT in the Value field,
Eastern Daylight Savings is used as the time zone setting for SYSPRINT for
the selected deployment manager or server.
- Click Apply, and then click Save to
save your changes.
- Stop and restart all of the affected application server that were
running when you made the time zone changes.
Results
Your new time zone setting are in affect for the designated servers.
