This property cannot be enabled unless you have enabled automatic demarcation/deactivation.

Automatic failover requires that your application use a cluster
of servers, so that redundant servers are available to run the application’s
components. The cluster must include at least one name server and
clients must resolve proxy references using naming services. See
“Load Balancing, Failover, and Component Availability” in the EAServer
System Administration Guide
for more information.

Valid values are TRUE and FALSE.
This property must be set to TRUE for live editing
but should be set to FALSE otherwise to improve
scalability.

By default, the component uses the server’s coded
character set (specified on the General tab in the Server Properties
window). For European or Asian languages, you may need to set this
property to a value such as iso_1 or big5.

This is a comma-separated list of IDL interface names, each
of which takes the form: module::interface.

To release idle pooled instances, EAServer has
a garbage collector thread that runs periodically. Each time it
runs, the garbage collector removes one idle instance from the pool,
unless the minimum pool size has been reached. The default is 0.

If the maximum pool size is reached, EAServer destroys
excess instances after deactivation. The default is 0, which means
no maximum pool size is in effect.

The value must take the form: package/component

The path takes this form: RepositoryComponentpackagecomponentCcookie

When a library name has a prepended dollar sign ($), EAServer assumes that its location
is relative to the EAServer Repository
directory. When a library name does not have a prepended dollar
sign, EAServer assumes the name
specifies an absolute path.

See “Live editing”.

When the pooling property is set to TRUE,
the component is always pooled and the CanBePooled event is never
triggered. When the pooling property is set to FALSE,
the CanBePooled event is triggered, allowing selective refusal of
pooling.

If the tx_vote property is set to FALSE,
the component is pooled after each method; otherwise, it is pooled
at the end of the transaction.

When the sharing property is set to TRUE,
all clients share a single component instance. Pooling options do
not apply to shared components.

To make a shared component a service, add it to the list of
services specified for the com.EAServer.server.services
property.

For PowerBuilder, the named type is a user-defined structure
that must encapsulate all data to be persisted. When you select
Automatic Persistent State, enter the name of the structure in the
State text box on the Persistence tab page, and click OK, default
values are supplied for other properties on the page. Stateful failover
is supported for PowerBuilder components when using automatic persistence.
For more information, see the chapter on managing persistent component
state in the EAServer Programmer’s Guide
.

The default is: getState, setState

Setting this property has the same effect as setting the
tx_vote property to FALSE, but it also
disables the activate and deactivate events. Do not set this
property if you want to specify that a component is stateless. Instead, set
pooling to TRUE and tx_vote to FALSE.

Required when using automatic persistence, or when using component-managed
persistence with an implementation that delegates to EAServer’s built-in storage
component. The default is: CtsComponents/JdbcStorage

Also specifies the connection cache and table used by the
storage component.

For more information see “Concurrency property”.

The allowable settings are:

• always The default. The server sends the exception to the client
  when a transaction is rolled back.
• failed EAServer does not send the
  exception to the client when a transaction is rolled back. If you
  use this setting, you can code your components to raise a different
  exception with a descriptive message after calling the RollbackWork
  transaction primitive.

With
the failed setting in effect, EAServer may
still throw a CORBA system exception if unable to commit a transaction
at your component’s request.You can set this property to
failed if you require that no exceptions be sent to the client for
rolled-back transactions or that an alternative exception be sent.
This setting is useful if you require that the client be able to
retrieve output parameters after a transaction is rolled back: if
an exception is thrown, the output parameters are not available.

EAServer checks for timeouts
after each method returns.

Valid values are:

• not_supported
• supports
• requires
• requires_new
• mandatory
• user-managed
• never

When tx_vote is set to TRUE, the
component must control transaction state and component deactivation
by explicitly calling methods of the TransactionServer service object.

When tx_vote is set to FALSE, EAServer automatically deactivates
the component after each method invocation. You do not need to make
explicit calls to SetComplete to cause deactivation
because SetComplete is assumed by default. To
override the default state, you can call SetAbort.

For PowerBuilder objects, EAServer sets
this property to pb.
