LogRecord Class

Represents an unstructured log record delivered as a COM+ CrmLogRecordRead structure. This class cannot be inherited.

Namespace: System.EnterpriseServices.CompensatingResourceManager
Assembly: System.EnterpriseServices (in system.enterpriseservices.dll)

public sealed class LogRecord
public final class LogRecord
public final class LogRecord

Unstructured log records are delivered as a COM+ CrmLogRecordRead structure. In addition to the user data (a single BLOB), this contains additional fields that are useful for debugging or fault finding. The Flags field is a bit field that provides further information about whether this record was forgotten at some point, and when it was written. The Sequence field provides the sequence number of the log record. In most cases, sequence numbers are sequential but are not necessarily contiguous due to internal log records that are not delivered to the Compensating Resource Manager (CRM) Compensator.

The following code example demonstrates the use of this class.

public override bool AbortRecord (LogRecord log)
{

    // Check the validity of the record.
    if (log == null) return(true);
    Object[] record = log.Record as Object[];
    if (record == null) return(true);
    if (record.Length != 2) return(true);

    // Extract old account data from the record.
    string filename = (string) record[0];
    int balance = (int) record[1];
 
    // Restore the old state of the account.
    AccountManager.WriteAccountBalance(filename, balance);

    return(false);
}

public boolean AbortRecord(LogRecord log)
{
    // Check the validity of the record.
    if (log == null) {
        return true;
    }
    Object record[] = new Object[] { log.get_Record() };

    if (record == null) {
        return true;
    }
    if (record.get_Length() != 2) {
        return true;
    }
    // Extract old account data from the record.
    String fileName = (String)(record.get_Item(0));
    int balance = System.Convert.ToInt32(record[1]);

    // Restore the old state of the account.
    AccountManager.WriteAccountBalance(fileName, balance);

    return false;
} //AbortRecord
