show open transactions

show open transactions

Displays a list of open transactions.

Syntax

show open transactions 
configuration_name

Parameters

The following table describes the command parameter:
Parameter
Description
configuration_name
The name of the configuration for which to display open transactions.

Example

The following example command lists open transactions for the Oracle2Oracle configuration: 
show open transactions Oracle2Oracle

Sample Output

The following sample output is for a configuration with an Oracle source: 
Transaction #0
Transaction Name: 'qwerty'
XID: '0x0009.007.0001b473'
Begin Transaction SCN: '0x0003.3f65f2f0'
Loopback Transaction: 'false'
Records in Transaction: '9'
Redo Thread ID: '1'
System Table Transaction: '0'
Begin Transaction Timestamp: 'Apr 1, 2014 2:13:43 PM'
Undo Block Address (UBA): '0x00c00100.0001b473.0007'
Session ID: '14'
Session Serial Number: '11279'
Internal SCN: '13948547824 0'
Internal XID: '2533304855278707'
Transaction size (in bytes): '1584'
Database Transaction Status: 'ACTIVE'
Database User Name: 'SRC'
System User: 'abobkov'
Host: 'KZW178313'
The following table describes the properties of open transactions that can appear in the output, depending on the source type and whether the transaction is marked for commit or rollback processing:
Property
Description
Transaction
A transaction counter that the Server Manager CLI generates to list open transactions. The counter uses the format
#
number
. The
number
 value begins at 0 and is incremented by 1 for each subsequent open transaction for the specified configuration.
Transaction Name
The name of the open transaction.
XID
The transaction ID of the open transaction.
For Oracle sources, the Server Manager CLI might list multiple open transactions with the same XID value if Oracle reuses transaction IDs. When listing these transactions, the command first lists the transactions for unmapped tables that do not have a
Begin Transaction Timestamp
 and then lists the other transactions in chronological order, beginning with the transaction that has the earliest
Begin Transaction Timestamp
.
Begin Transaction LSN or Begin Transaction SCN (for Oracle sources)
The SCN or LSN value for the BEGIN TRANSACTION operation.
Loopback Transaction
Indicates whether the Extractor skips the transaction based on the transaction name. The Extractor skips transactions if their names are specified in the
SKIP_TX
 command line parameter. If the
SKIP_DEFAULT_TX
 parameter is set to Y, the Extractor also skips transactions that have the default name of DbSyncTransaction. Valid values are:
  • true
    . The Extractor skips the transaction.
  • false
    . The Extractor does not skip the transaction.
Records in Transaction
The number of records in the transaction that are available in intermediate files.
Database ID or Redo Thread ID (for Oracle sources)
For Oracle sources, the unique identifier of a redo thread. For other sources, the unique identifier of a database.
DDL Transaction or System Table Transaction (for Oracle sources)
Indicates whether the transaction affects database system tables. A transaction that affects database system tables usually includes DDL operations. The database system tables that Data Replication monitors are specified in the following parameters in the
DataReplication_installation
/uiconf/default.cfg file:
  • db2_fixed_source_tables_names
  • mssql_fixed_source_tables_names
  • oracle_fixed_source_tables_names
Valid values are:
  • 0
    . The transaction does not affect system tables.
  • 1
    . The transaction affects system tables.
Begin Transaction Timestamp
The date and time of the first redo record for the mapped table. This value displays only if the transaction includes changes to a mapped table in the configuration. If the transaction includes changes to an unmapped source table, the
Begin Transaction Timestamp
 property does not contain a value.
Undo Block Address (UBA)
For Oracle sources, specifies the Undo Block Address.
Session ID
For Oracle sources, specifies the identifier of the session that is associated with the open transaction.
Session Serial Number
For Oracle sources, specifies the serial number of the session that is associated with the open transaction.
Internal LSN or (for Oracle) Internal SCN
The LSN or SCN value for the BEGIN TRANSACTION operation in the database format.
Internal XID
The transaction ID in the database format.
Transaction size
The amount of data, in bytes, in the transaction records in the intermediate files.
Database Transaction Status
The status of the transaction that is reported by the source database. If the source database does not contain information about the transaction, Data Replication sets the transaction status to NOT ACTIVE.
Database User Name
The name of the database user who opened the transaction.
System User
The name of the system user who opened the transaction.
Host
The IP address or host name of the system with the database client that opened the transaction.
Application ID
For DB2 sources, the ID of the database client that opened the transaction.
