  mode                   (IN) - mode (see NOTES)
NOTES
  - Parameter src_time is optional. If specified the appropriate return 
    structure must be pre-allocated before calling OCILCRHeaderGet.
  - The return values for src_db_name, cmd_type, owner, oname, tag, txid and 
    position are shallow-copied (i.e., they point directly into the LCR 
    structure).  
  - Valid mode flags:
    - OCILCR_NEW_ONLY_MODE: if this mode is specified then the new_columns 
      returned is the count of the columns in the NEW column list only.  
      Otherwise, the new_columns returned is the number of distinct 
      columns present in either the NEW or the OLD column list of the given 
      ROW LCR.

   PARAMETERS
       svchp                      (IN/OUT) - OCI service handle

   RETURNS
       OCI_SUCCESS or OCI_ERROR.
   NOTES
     - For now, specify OCI_DEFAULT for mode
     - If array_size is not large enough to accommodate the number of columns
       in the requested column list then OCI_ERROR is returned. Expected 
       array_size is returned through num_bind_var parameter. 
     - bind_var_syntax for oracle should contain ":". This will generate 
       positional binds such as :1, :2, :3 etc. For other non-oracle databases
       they can give the string that needs to be used for binds. 
     - WHERE clause generated for INSERT lcr will have all the columns that
       are being inserted. This WHERE clause could be used to identify the 
       inserted row after inserting. (like "returning ROWID").
       INSERT INTO TAB(COL1) VALUES (10) -> WHERE COL1=10
     - WHERE clause generated for UPDATE will have all the columns in the
       old column list. However the values of the columns will be that of 
       new column value of the column if it exist in the new values
       of the UPDATE. If the column appears only in the old column then
       old column value will be used.
       UPDATE TAB SET COL1 = 10 WHERE COL1 = 20 -> WHERE COL1 = 10
       UPDATE TAB SET COL2 = 20 WHERE COL1 = 20 -> WHERE COL1 = 20
     - WHERE clause for DELETE will use the columns and values from 
       old column lst
     - LOB piecewise operations would use the new columns and values for
       generating the WHERE clause.

   NOTES
       Specify OCI_DEFAULT for the mode parameter.

       The name of the outbound server must be provided because multiple

       of the stream. This call returns OCI_ERROR if the specified position 
       is non-null and less than the server's processed low-watermark; 
       otherwise, LCRs with position greater than last_position will be
       sent to the user.

       If last_position is null then the stream will start from the processed 
       low-watermark maintained in the server.

   NAME
       OCIXStreamOutProcessedLWMSet - Set Processed Low-Watermark
   DESCRIPTION
       Sets the processed low-watermark maintained at the client.
   PARAMETERS
       svchp                  (IN/OUT) - OCI service handle
       errhp                  (IN/OUT) - Error Handle for error reporting
       processed_low_position     (IN) - processed low position.
       processed_low_position_len (IN) - processed low position length.
       mode                       (IN) - mode for future extension. (Not used 
                                         currently).
   RETURNS
       OCI_SUCCESS or OCI_ERROR.

   NOTES
       The processed low-watermark denotes all LCRs at or below this position
       have been processed. After successfully attaching to an XStream 
       outbound server, a local copy of the processed low-watermark is 
       maintained at the client. Periodically, this watermark is sent to the 
       server so that archived logs containing already processed transactions 
       can be purged. 

       The following API is used to update the local copy of the processed 
       low-watermark. It can be called anytime between OCIXStreamOutAttach 
       and OCIXStreamOutDetach calls. Clients, using the callback mechanism 
       to stream LCRs from the server, can invoke this API while 
       in the callback functions.

/*
   NAME
       OCIXStreamOutLCRCallbackReceive - OCI Receive LCR stream using Callbacks
   DESCRIPTION
       This API is used to get the LCR stream from the outbound server using 
       callbacks to gain better performance. The user must supply a callback 
       function to be invoked for each LCR received. If some row changes 
       in the stream may contain LOB/LONG/XMLType columns then the data for
       those columns are returned to the user in chunks. To receive those row
       changes, the user must provide a second callback to be invoked to
       process each chunk data.

       If there is an LCR available in the stream, the processlcr_cb function 
       is invoked immediately. After the processlcr_cb function exits, if the 
       current LCR contains additional chunks then the processchunk_cb function
       is invoked for each chunk belonging to that LCR.  

       If there is no LCR in the stream when the idle timeout expires (see
       OCI_ATTR_XSTREAM_IDLE_TIMEOUT), this call returns a null LCR with 
       OCI_SUCCESS code.
   PARAMETERS
       svchp                  (IN/OUT) - OCI service handle
       errhp                  (IN/OUT) - Error Handle for error reporting
       processlcr_cb              (IN) - Client callback function for each LCR.
       processchunk_cb            (IN) - Client callback function for each 
                                         chunk.
       usrctxp                    (IN) - Client context. (Optional)
       fetch_low_position         (OUT)- Fetch low watermark. (Optional)
       fetch_low_position_len     (OUT)- Fetch low watermark length.
       mode                       (IN) - mode for future extension. (Not used 
                                         currently).
   RETURNS
       OCI_SUCCESS or OCI_ERROR.
   NOTES
      - The fetch low watermark is used to indicate all transactions
        with commit position below this have been received by the XStream
        outbound server.

      - If the LCR contains non-chunked column(s), the duration of that LCR is
        limited to the processlcr_cb function. If the LCR contains some 
        chunk data then the duration of the LCR is extended until all the 
        chunks have been processed (that is, when the flag passing to
        processchunk_cb function does not have OCI_XSTREAM_MORE_ROW_DATA flag
        set). If the user wants to access the LCR data at a later time, a 
        copy of the LCR must be made.  The client callback should not modify 
        or free the LCR passing to the callback. 

        If the OCIXSTREAM_OUT_ATTACH_APP_FREE_LCR mode is passed to 
        OCIXStreamOutAttach call then the application is in charge of calling
        OCILCRFree to free each LCR. Note, this mode does not apply to the 
        chunk data associated with each LCR. Each chunk data is freed 
        immediately after each OCIXStreamOutChunkReceive call.
        
      - The given usrctxp is passed to both callbacks.

      - An ACK interval is the interval in seconds which the outbound
        server receives the processed LWM or the inbound server sends 
        the processed LWM.  The default ACK interval is 30 seconds. This 
        value can be changed by setting the OCI_ATTR_XSTREAM_ACK_INTERVAL 
        attribute using OCIAttrSet API.  This attribute is checked only 
        during the Attach call; thus, it must be set before invoking this API. 

      - The idle timeout is the interval in seconds after which the current 
        call will terminate if there is no LCR in the stream. The default 
        idle timeout is one second. This value can be changed by setting the 
        OCI_ATTR_XSTREAM_IDLE_TIMEOUT attribute using OCIAttrSet API.  This 
        attribute is checked only during the Attach call; thus, it must be 
        set before invoking this API. 

      - The outbound server ends each call at the transaction boundary 
        after an ACK interval has elapsed since the start of the call
        or when the idle timeout expires. This API returns the fetch 
        low watermark at the end of each call.

   NAME
       OCIXStreamOutLCRReceive - Receive LCR without using callback 
   DESCRIPTION
       This API is used to receive an LCR from an outbound stream. If there 
       is an LCR available, this API immediately returns that LCR. 
       When there is no LCR available in the stream, this call returns a 
       null LCR after the idle timeout (see OCI_ATTR_XSTREAM_IDLE_TIMEOUT)
       has expired.

       The client must not modify the LCR received from the outbound server.
       The duration of each LCR is until the next OCIXStreamOutLCRReceive call.
       If the OCIXSTREAM_OUT_ATTACH_APP_FREE_LCR mode is passed to 
       OCIXStreamOutAttach call then the application is in charge of calling
       OCILCRFree to free each LCR. Note, this mode does not apply to the 
       chunk data associated with each LCR. Each chunk data is freed 
       immediately after each OCIXStreamOutChunkReceive call.

       To avoid network round trip for every OCIXStreamOutLCRReceive call, 
       the connection is tied to this call to let the server fill up 
       the network buffer with LCRs so subsequent calls can quickly receive 
       the LCRs from the network. The server ends each call at the 
       transaction boundary after an ACK interval has elapsed since the start
       of the call or when the idle timeout expires. See 
       OCI_ATTR_XSTREAM_ACK_INTERVAL & OCI_ATTR_XSTREAM_IDLE_TIMEOUT
       attributes.

                                         currently).
   RETURNS
     -  OCI_STILL_EXECUTING means the current call is still in progress. The 
        connection associated with the specified service context handle is 
        still tied to this call for streaming the LCRs from the server. An 
        error is returned if the user attempts to use the same connection to 
        execute any OCI calls that require database round trip, for example, 
        OCIStmtExecute, OCIStmtFetch, OCILobRead, etc. OCILcr* calls are 
        local calls; thus, they are valid while the stream is in progress.
     -  OCI_SUCCESS means the current call is completed. User is free to 
        execute OCIStmt*, OCILob*, etc. from the same service context.
     -  OCI_ERROR means the current call encounters some errors. Use 
        OCIErrorGet to obtain information about the error.

   NOTES
     This call always returns a null LCR when the return code is OCI_SUCCESS. 
     In addition, it returns the fetch low position to denote the outbound 
     server has received all transactions with commit position lower than or 
     equal to this value.

     The fetch low watermark is used to indicate all transactions
     with commit position below this have been received by the XStream

   NAME
       OCIXStreamInLCRCallbackSend - OCI XStream In Send LCR to Inbound Server
   DESCRIPTION
       Sends LCR stream to XStream inbound server using callbacks.
       The API invokes createlcr_cb function to obtain each LCR to send to the 
       server. If the return flag from the createlcr_cb function has 
       OCI_XSTREAM_MORE_ROW_DATA bit set, then it invokes createchunk_cb 
       procedure to obtain each chunk. It repeatedly calls createchunk_cb 
       function while the flag returned from this callback has 
       OCI_XSTREAM_MORE_ROW_DATA bit set. When this bit is not set, this API 
       cycles back to invoke createlcr_cb function to get the next LCR. 
       This cycle is repeated until the createlcr_cb function returns a null 
       LCR or when an ACK interval has elapsed since the start of the call.
       See OCI_ATTR_XSTREAM_ACK_INTERVAL attribute.

 - This function is valid only if the associated LCR's cmd type is
   INSERT, UPDATE or LOB_WRITE. It can be invoked multiple times for the
   same LCR. 

 - This API is not valid for LOB_ERASE and LOB_TRIM LCRs.

 - The chunk values for different columns can not be interleaved. If a 
   column contains multiple chunks, this procedure must be called 
   consecutively using the same column name before proceeding to a new column. 
   The ordering in which the LOB/LONG/XMLType column values are set is 
   irrelevant. 

 - The OCI_LCR_COLUMN_LAST_CHUNK must be specified for the last chunk of
   each column. 

 - Only one column can be specified for LOB_WRITE operation.

 - For NCLOB or varying width CLOB, the input buffer must be in 
   AL16UTF16 format.

 - For INSERT operation, each LOB/LONG/XMLType column, with value set using 
   OCIXStreamInChunkSend, must be included in the current LCR's NEW

   DESCRIPTION
       Commits current transaction
   PARAMETERS
       svchp                      (IN/OUT) - OCI service handle
       errhp                      (IN/OUT) - Error Handle to which errors
                                             should be reported
       lcrp                           (IN) - Pointer to the LCR to send. Must
                                             be a commit LCR.
       mode                           (IN) - Mode flags (For future extension.
                                             Not used currently)
   RETURNS
       OCI_SUCCESS or OCI_ERROR.
   NOTES
       The position of the input LCR must be higher than
       DBA_XSTREAM_INBOUND_PROGRESS.APPLIED_HIGH_POSITION and the LCR's source
       database must match DBA_APPLY_PROGRESS.SOURCE_DATABASE of the attached
       inbound server.

       Upon receiving this LCR, the inbound server will check if there is any
       unapplied complete or rollback transaction remaining. If none is found
       it inserts a row to the apply progress table based on the input LCR and
       commit the current transaction; otherwise, it returns an error.

       If there is any pre-commit handler defined, it will be executed when
       this commit LCR is executed.

   NAME
     OCIXStreamInErrorGet - OCI XStream In Get Error Info
   DESCRIPTION
     Returns the first error encountered by the inbound server since the 
     Attach call.
   PARAMETERS
     svchp                      (IN/OUT) - OCI service handle
     errhp                      (IN/OUT) - Error Handle
     errcodep                   (OUT)    - Error code
     msgbuf                     (IN/OUT) - Pre-allocated message buffer
     msg_bufsize                (IN)     - Message buffer size
     msg_len                    (OUT)    - Length of returned error message
     txn_id                     (IN/OUT) - Pre-allocated txn id buffer
     txn_id_bufsize             (IN)     - Txn_id buffer size
     txn_id_len                 (OUT)    - Length of returned txn id
   RETURNS
     OCI_SUCCESS or OCI_ERROR.
   NOTES
     The maximum size for the returned txn id is OCI_LCR_MAX_TXID_LEN. If the 
     allocated buffer for txn_id is too small, this routine returns ORA-29258.
     The maximum size for the returned error msg is OCI_ERROR_MAXMSG_SIZE. If
     the allocated size for msgbuf is too small, the returned message will be
     truncated.
