You can create a management profile for the administrative
agent to administer multiple application servers that run customer
applications only. The administrative agent provides a single administrative
console to administer the application servers.
Before you begin
Before
you use the Profile Management Tool,
install the product files.
The Profile Management Tool is the graphical
user interface for the manageprofiles command. See
the description of the manageprofiles command
for more information.
You must
provide enough system temporary space to create a profile. For information,
read about the file system requirements for profiles.
Attention: When you launch the Profile Management Tool, the tool could
lock up in the following situation for a non-root user: Log into a
machine as root, use the SetPermissions utility to change the user
from x to y. Assume that you are user x and log
back into the machine. Launch the Profile Management Tool, click Profile Management Tool, and click Create.
The next click after the click on Create could lock up the
tool.
Attention: When
you use the
Profile Management Tool with
the Motif graphical user interface on the Solaris operating system,
the default size of the
Profile Management Tool might
be too small to view all the messages and buttons of the
Profile Management Tool. To fix the problem,
add the following lines to the
app_server_root/.Xdefaults
file:
Eclipse*spacing:0
Eclipse*fontList:-misc-fixed-medium-r-normal-*-10-100-75-75-c-60-iso8859-1
After
adding the lines, run the following command before launching the
Profile Management Tool:
xrdb -load user_home/.Xdefaults
- Start the Profile Management Tool to create a new
runtime environment.
You can use one of
the following ways to start the tool.
- Click Launch Profile Management Tool,
and then click Create on the Profiles tab to create a new profile.
The Profiles tab contains a list of profiles that have been
created on your machine. No action can be done on a selected profile
unless the profile can be augmented. The Augment button is greyed
out unless a profile that you select can be augmented.
The tool
displays the Environment selection panel.
-
The Server type selection panel is displayed.
- Select Administrative agent, and click Next.
The Profile creation options
panel is displayed.
- If you selected Typical profile creation,
go to the step on administrative
security.
- If you selected Advanced profile creation, optionally
select to deploy the administrative console and then click Next.
If you chose not to deploy
the administrative console, then the administrative console ports
are disabled on the Ports panel.
The
tool displays the Profile name and location panel.
- Specify a name for the profile and
the directory path for the profile directory, or accept the default
values. Then, click Next.
Profile
naming guidelines: Double-byte characters are supported. The profile
name can be any unique name with the following restrictions. Do not
use any of the following characters when naming your profile:
- Spaces
- Special characters that are not supported within the name of a
directory on your operating system, such as *&?
- Slashes (/) or (\)
The default profile
The
first profile that you create on a machine is the default profile.
The default profile is the default target for commands that are issued
from the bin directory in the product installation root.
When only one profile exists on a machine, every command works on
the single server process in the configuration. You can make another
profile the default profile when you create that profile by checking Make
this profile the default on the Profile name and location panel
of the Advanced profile creation path. You can also make another
profile the default profile using the manageprofiles command after
you create the profile.
Addressing a profile
in a multiprofile environment
When multiple
profiles exist on a machine, certain commands require that you specify
the profile to which the command applies if the profile is not the
default profile. These commands use the -profileName parameter to
identify which profile to address. You might find it easier to use
the commands that are in the bin directory of each profile.
Use these commands to query the command shell to determine
the calling profile and to address these commands to the calling profile.
Default profile information
The default profile name
is
<profile_type><profile_number>:
- <profile_type> is a
value of AppSrv, Dmgr, Custom, AdminAgent, JobMgr,
or SecureProxySrv.
- <profile_number> is
a sequential number that is used to create a unique profile name
The
default profile directory is app_server_root/profiles,
where app_server_root is the installation root.
The default profile directory
is app_server_root\profiles, where app_server_root is
the installation root.
- On the Node, host, and cell names panel, specify a unique
node name, the actual host name of the machine, and a unique cell
name. Click Next.
Table 1. Characteristics
of the administrative agent node. This table shows
the characteristics of the administrative agent node.
Field name |
Default value |
Constraints |
Description |
Node name |
shortHostName
AANode
NodeNumber
where:
- shortHostName is the short host name.
- NodeNumber is a sequential number starting at 01.
|
Use a unique name for the administrative agent. |
The name is used for administration within the
administrative agent cell. |
Host name |
The long form of the domain name server
(DNS) name.
|
The host name must be addressable through your
network. Read about Host
name considerations.
|
Use the actual DNS name or IP address of your
machine to enable communication with your machine. See additional
information about the host name that follows this table. |
Cell name |
shortHostName
Cell
CellNumber
where:
- shortHostName is the short host name.
- CellNumber is a sequential number starting at 01.
|
Use a unique name for the cell. If you plan
to migrate a Version 5 or Version 6 cell to Version 7, use the same
cell name as the Version 5 or Version 6 cell. A cell name must be unique in any circumstance in which the product is running on the same physical machine or cluster of machines, such as a sysplex. Additionally, a cell name must be unique in any circumstance in which network connectivity between entities is required either between the cells or from a client that must communicate with each of the cells. Cell names must also be unique if their namespaces are federated. Otherwise, you might encounter symptoms such as a javax.naming.NameNotFoundException error, in which case, create uniquely named cells. |
All federated nodes become members of the cell,
which you name in this panel. |
Reserved names: Avoid using reserved folder
names as field values. The use of reserved folder names can cause
unpredictable results. The following terms are reserved folder names:
- cells
- nodes
- servers
- clusters
- applications
- deployments
Directory
path length
The number
of characters in the profiles_directory_path\profile_name directory
must be less than or equal to 80 characters.
Host name considerations
The host name is the network
name for the physical machine on which the node is installed. The
host name must resolve to a physical network node on the server. When
multiple network cards exist in the server, the host name or IP address
must resolve to one of the network cards. Remote nodes use the host
name to connect to and communicate with this node. Selecting a host
name that other machines can reach within your network is important.
Do not use the generic identifier, localhost, for
this value. Also, do not attempt to install WebSphere Application
Server products on a machine with a host name that uses characters
from a double-byte character set (DBCS). DBCS characters are not supported
when used in the host name.
If you define coexisting
nodes on the same computer with unique IP addresses, then define each
IP address in a domain name server (DNS) look-up table. Configuration
files for standalone application servers do not provide domain name
resolution for multiple IP addresses on a machine with a single network
address.
The value that you specify for the host
name is used as the value of the hostName property in configuration
documents for the standalone application server. Specify the host
name value in one of the following formats:
- Fully qualified domain name server (DNS) host name string, such
as xmachine.manhattan.ibm.com
- The default short DNS host name string, such as xmachine
- Numeric IP address, such as 127.1.255.3
The fully qualified DNS host name has the
advantages of being unambiguous and flexible. You have the flexibility
of changing the actual IP address for the host system without having
to change the application server configuration. This value for the
host name is particularly useful if you plan to change the IP address
frequently when using Dynamic Host Configuration Protocol (DHCP) to
assign IP addresses. A disadvantage of this format is dependency on
DNS. If DNS is not available, then connectivity is compromised.
The short host name is also dynamically resolvable. A
short name format has the added function of being redefined in the
local hosts file so that the system can run the application server,
even when disconnected from the network. To run disconnected, define
the short name as the loopback address, 127.0.0.1,
in the hosts file to run disconnected. A disadvantage of this format
is a dependency on DNS for remote access. If DNS is not available,
then connectivity is compromised.
A numeric IP address
has the advantage of not requiring name resolution through DNS. A
remote node can connect to the node that you name with a numeric IP
address without DNS being available. A disadvantage of this format
is that the numeric IP address is fixed. You must change the setting
of the hostName property in Express configuration documents whenever
you change the machine IP address. Therefore, do not use a numeric
IP address if you use DHCP, or if you change IP addresses regularly.
Another disadvantage of this format is that you cannot use the node
if the host is disconnected from the network.
After displaying
characteristics, the tool displays the Administrative security panel.
- Optionally enable administrative security,
and click Next.
You can enable
administrative security now during profile creation, or later from
the console. If you enable administrative security now, then enter
a user name and password to log onto the administrative console.
After specifying security characteristics, the tool
displays the Security certificate panel if you previously selected Advanced
profile creation.
- If you selected Typical profile creation at the
beginning of these steps, then go to the step that displays the Profile
summary panel.
- Verify that the ports within the administrative agent
profile are unique, or intentionally conflicting, and click Next.
If you chose not to deploy
the administrative console, then the administrative console ports
are disabled on the Ports panel.
Port conflict resolution
Ports are recognized as being in use if one of the following
conditions exists:
- The ports are assigned to a profile created from an installation
that is performed by the current user.
- The port is currently in use.
Validation of ports occurs when you access the Port value assignment
panel. Conflicts can still occur between the Port value assignment
panel and the Profile creation complete panel because ports are not
assigned until profile creation completes.
The
tool displays the Windows® service definition panel
if you are installing on a Windows operating
system and the installation ID has the administrative group privilege.
The tool displays the Linux service definition panel
if you are installing on a supported Linux operating
system and the ID that runs the Profile Management Tool is
the root user.
- Choose whether to run the
administrative agent process as a Windows service
on a Windows operating system
or as a Linux service on a Linux operating system, and click Next.
The Windows service
definition panel is displayed for the Windows operating
system only if the ID that installs the Windows service
has the administrator group privilege. However, you can run the WASService.exe
command to create the Windows service
as long as the installer ID belongs to the administrator group. Read
about automatically restarting server processes for more information.
The product attempts to start Windows services for administrative agent
processes that are started by a startServer command. For example,
if you configure an administrative agent as a Windows service and issue the startServer
command, then the wasservice command attempts to start the
defined service.
If you chose
to install a local system service, then you do not have to specify
your user ID or password. If you create a specified user type of service,
then you must specify the user ID and the password for the user who
runs the service. The user must have Log on as a service authority
for the service to run correctly. If the user
does not have Log on as a service authority, then
the Profile Management tool automatically adds the authority.
To perform this profile creation task, the user ID
must not contain spaces. In addition to belonging to the administrator
group, the ID must also have the advanced user right of Log
on as a service. The Installation wizard grants the user
ID the advanced user right if the user ID does not already have the
advanced user right and if the user ID belongs to the administrator
group.
You can also create other Windows services
after the installation is complete to start other server processes.
Read about automatically restarting server processes for more information.
You can remove the Windows service
that is added during profile creation during profile deletion. You
can also remove the Windows service with the wasservice
command.
IPv6 considerations
Profiles created
to run as a Windows service
fail to start when using Internet Protocol version 6 (IPv6) if the
service is configured to run as local system. Create a user-specific
environment variable to enable IPv6. Since this environment variable
is a user variable instead of a local system variable, only a Windows service that runs as
that specific user can access this environment variable. By default,
when a new profile is created and configured to run as a Windows service, the service is set to run
as local system. When the Windows service
for the administrative agent process attempts to run, the service
is unable to access the user environment variable that specifies IPv6,
and thus, attempts to start as IPv4. The server does not start correctly
in this case. To resolve the problem, when creating the profile, specify
that the Windows service
for the administrative agent process runs as the same user ID from
which the environment variable that specifies IPv6 is defined, instead
of as local system.
Default Windows service
information
![[Windows]](../../windows.gif)
The following default
values for the Windows service definition panel
exist:
- The default is to run as a Windows service.
- The service process is selected to run as a system account.
- The user account is the current user name. User name requirements
are the requirements that the Windows operating
system imposes for a user ID.
- The startup type is automatic. The values for
the startup type are those values that the Windows operating
system imposes. If you want a startup type other than automatic,
you can either select another available option from the menu or change
the startup type after you create the profile. You can also remove
the created service after profile creation, and add it later with
the desired startup type. You can choose not to create a service at
profile creation time and optionally create the service later with
the desired startup type.
The Linux service
definition panel is displayed if the current operating system is a
supported version of Linux operating systems, and the
current user has the appropriate permissions.
The
product attempts to start Linux services for application
server processes that are started by a startServer command. For example,
if you configure an application server as a Linux service
and issue the startServer command, then the wasservice command
attempts to start the defined service.
By default,
the product is not selected to run as a Linux service.
To create the service, the user that runs the Profile Management Tool must be the root
user. If you run the Profile Management Tool with
a non-root user ID, then the Linux service
definition panel is not displayed, and no service is created.
When you create a Linux service,
you must specify a user name from which the service runs.
To delete a Linux service, the user must be
the root user or have appropriate privileges for deleting the service.
Otherwise, a removal script is created that the root user can run
to delete the service for the user.
The tool displays
the Profile creation summary panel.
- Click Create to create the management
profile for the administrative agent, or click Back to change
the characteristics of the profile.
The Profile creation progress
panel, which shows the configuration commands that are running, is
displayed.
When the profile creation completes,
the tool displays the Profile creation complete panel.
- Optionally, select Launch the First steps
console. Click Finish to exit.
With the First
steps console, you can create additional profiles and start the application
server.
