Note that this applies for the "in-use" connections of connection and session pools also. The initial steps of allocating and initializing session handles are omitted here for clarity. Oracle recommends for applications to register a callback, so when failover happens, the callback can be used to restore the session to the desired state. User callbacks can both be registered statically in the application itself or dynamically at runtime in the DLLs. Flow control can be enabled to prevent applications from flooding the shared memory when the message consumers are slow or have stopped for some reason.

    The following are the hexadecimal representation of the flag and the semantic meaning of that value. Note that some are nonsensical and some are not possible. TCP flags are used within TCP packet transfers to indicate a particular connection state or provide additional information.

    There are a few TCP flags that are much more commonly used than others as such “SYN”, “ACK”, and “FIN”. SYN - The SYN, or Synchronisation flag, is used as a. In an effort to prevent this many sites have turned to the TCP keep-alive feature. There are better ways to convert each hexit to a numerical value but a case ip_id; /* ID */ unsigned short ip_flags_off; /* flags and fragment offset */ char ip_ttl; .
    In this area the client can keep any necessary state or context.

    Hence, pooling should be used in conjunction with short tasks and the size of the pool should be sufficiently large to maintain the desired concurrency of transactions.

    These sessions will be handed over to thin clients as requested. The resource is unavailable to other threads during its period of use. Performing pre- or post-processing code for specific OCI calls.

    Transparent Application Failover in OCI Transparent Application Failover TAF is a client-side feature designed to minimize disruptions to end-user applications that occur when database connectivity fails because of instance or network failure.

    However, once an attribute is changed, it will remain set on the underlying physical session.

    If failover is unsuccessful, then the callback is called to inform the application that failover cannot occur. The usage is the same. Homogeneous and Heterogeneous Session Pools A session pool can be either homogeneous or heterogeneous.

    Shrinkage of the pool only occurs when there is a network round-trip.

    It is read-only. However, once an attribute is changed, it will remain set on the underlying physical session. The tag is used to search the cache. Note: This program does not modify the session state such as NLS parameters, and so forth.

    There are several OCI functions that you can use as callbacks from external procedures. OCISessionGet is the recommended uniform function call to retrieve a session.

    The application data such as bind and define buffers can be enclosed in the opaque context.

    Suppose an user employs a Web browser to log in to an application server that accesses a back-end database server. Table Enqueue Option Attributes. This is explained later in this section. This mode should be used when there is more than one server DN in the server DN descriptor or you are sure that a database connection is not available.
