_CORBA_MODULE_VAR _core_attr CORBA::Boolean dumpConfiguration;
//  Set to 1 to cause the ORB to dump the current set of configuration
//  parameters.
//
//  Valid values = 0 or 1

_CORBA_MODULE_VAR _core_attr GIOP::Version maxGIOPVersion;
//  Set the maximum GIOP version the ORB should support. The ORB tries
//  to match the <major>.<minor> version as specified. This function
//  should only be called before ORB_init(). Calling this function
//  after ORB_init() does not cause the ORB to change its maximum
//  supported version; in this case the ORB just returns its version
//  number in <major>.<minor>.
//
//  Valid values = 1.0 | 1.1 | 1.2

_CORBA_MODULE_VAR _core_attr CORBA::ULong giopMaxMsgSize;
//   This value defines the ORB-wide limit on the size of GIOP message 
//   (excluding the header). If this limit is exceeded, the ORB will
//   refuse to send or receive the message and raise a MARSHAL exception.
//
//   Valid values = (n >= 8192)
//


_CORBA_MODULE_VAR _core_attr omniCodeSet::NCS_C* nativeCharCodeSet;
//  set the native code set for char and string
//

_CORBA_MODULE_VAR _core_attr omniCodeSet::NCS_W* nativeWCharCodeSet;
//  set the native code set for wchar and wstring
//

_CORBA_MODULE_VAR _core_attr omniCodeSet::TCS_C* anyCharCodeSet;
//  set the preferred code set for char data inside anys
//

_CORBA_MODULE_VAR _core_attr omniCodeSet::TCS_W* anyWCharCodeSet;
//  set the preferred code set for wchar data inside anys
//

_CORBA_MODULE_VAR _core_attr CORBA::Boolean      lcdMode;
//  Set to 1 to enable 'Lowest Common Denominator' Mode.
//  This will disable various features of IIOP and GIOP which are
//  poorly supported by some ORBs, and disable warnings/errors when
//  certain types of erroneous message are received on the wire.
//
//  Valid values = 0 or 1
//


_CORBA_MODULE_VAR _core_attr CORBA::Boolean supportCurrent;
//  If the value of this variable is TRUE, per-thread information is
//  made available through the Current interfaces, e.g.
//  PortableServer::Current. If you do not need this information, you
//  can set the value to 0, resulting in a small performance
//  improvement.

_CORBA_MODULE_VAR _core_attr CORBA::Boolean strictIIOP;
//   Enable vigorous check on incoming IIOP messages
//
//   In some (sloppy) IIOP implementations, the message size value in
//   the header can be larger than the actual body size, i.e. there is
//   garbage at the end. As the spec does not say the message size
//   must match the body size exactly, this is not a clear violation
//   of the spec.
//
//   If this flag is non-zero, the incoming message is expected to
//   be well-behaved. Any messages that have garbage at the end will
//   be rejected.
//   
//   The default value of this flag is true, so invalid messages are
//   rejected. If you set it to zero, the ORB will silently skip the
//   unread part. The problem with this behaviour is that the header
//   message size may actually be garbage, caused by a bug in the
//   sender's code. The receiving thread may block forever on the
//   strand as it tries to read more data from it. In this case the
//   sender won't send any more as it thinks it has marshalled in all
//   the data.
//
//   Valid values = 0 or 1
//


_CORBA_MODULE_VAR _core_attr CORBA::ULong scanGranularity;
//  The granularity at which the ORB scans for idle connections.
//  This value determines the minimum value that inConScanPeriod or
//  outConScanPeriod can be implemented.
//
//  Valid values = (n >= 0 in seconds) 
//                  0 --> do not scan for idle connections.
//


_CORBA_MODULE_VAR _core_attr CORBA::ULong objectTableSize;
//  Hash table size of the Active Object Map. If this is zero, the ORB
//  uses a dynamically resized open hash table. This is normally the  
//  best option, but it leads to less predictable performance since   
//  any operation which adds or removes a table entry may trigger a   
//  resize. If you set this to a non-zero value, the hash table has   
//  the specified number of entries, and is never resized. Note that  
//  the hash table is open, so this does not limit the number of      
//  active objects, just how efficiently they can be located.
//
//  Valid values = (n >= 0)
//                 0 --> use a dynamically resized table.


_CORBA_MODULE_VAR _core_attr CORBA::Boolean abortOnInternalError;
//  If the value of this variable is TRUE then the ORB will abort
//  instead of throwing an exception when a fatal internal error is
//  detected. This is useful for debuging the ORB -- as the stack will
//  not be unwound by the exception handler, so a stack trace can be
//  obtained.
//  It is hoped that this will not often be needed by users of omniORB!
//
//  Valid values = 0 or 1


_CORBA_MODULE_VAR _core_attr CORBA::Boolean tcAliasExpand;
//   This flag is used to indicate whether TypeCodes associated with Anys
//   should have aliases removed. This functionality is included because
//   some ORBs will not recognise an Any containing a TypeCode with
//   aliases to be the same as the actual type contained in the Any. Note
//   that omniORB will always remove top-level aliases, but will not remove
//   aliases from TypeCodes that are members of other TypeCodes (e.g.
//   TypeCodes for members of structs etc.), unless tcAliasExpand is set to 1.
//   There is a performance penalty when inserting into an Any if 
//   tcAliasExpand is set to 1. The default value is 0 (i.e. aliases of
//   member TypeCodes are not expanded). Note that aliases won't be expanded
//   when one of the non-type-safe methods of inserting into an Any is
//   used (i.e. when the replace() member function or non - type-safe Any
//   constructor is used. )
//
//    Valid values = 0 or 1


_CORBA_MODULE_VAR _core_attr CORBA::Boolean useTypeCodeIndirections;
//   If true (the default), typecode indirections will be used. Set
//   this to false to disable that. Setting this to false might be
//   useful to interoperate with another ORB implementation that cannot
//   handle indirections properly.
//  
//   Valid values = 0 or 1

_CORBA_MODULE_VAR _core_attr CORBA::Boolean  acceptMisalignedTcIndirections;
//   If true, try to fix a mis-aligned indirection in a typecode. This
//   could be used to work around some versions of Visibroker's Java ORB.
//  
//   Valid values = 0 or 1

_CORBA_MODULE_VAR _core_attr CORBA::Boolean verifyObjectExistsAndType;
//  If the value of this variable is 0 then the ORB will not

_CORBA_MODULE_VAR _core_attr CORBA::ULong maxGIOPConnectionPerServer;
//  The ORB could open more than one connection to a server
//  depending on the number of concurrent invocations to the same
//  server. This variable decides the maximum number of connections 
//  to use per server. This variable is read only once at ORB_init.
//  If the number of concurrent invocations exceeds this number, the

_CORBA_MODULE_VAR _core_attr CORBA::Boolean offerBiDirectionalGIOP;
//   Applies to the client side. Set to 1 to indicates that the

//   calls. Set to 0 means the ORB should never do bidirectional.
//
//   Valid values = 0 or 1

_CORBA_MODULE_VAR _core_attr CORBA::Boolean  diiThrowsSysExceptions;
// If the value of this variable is 1 then the Dynamic Invacation Interface
// functions (Request::invoke, send_oneway, send_deferred, get_response,
// poll_response) will throw system exceptions as appropriate. Otherwise 
// the exception will be stored in the Environment pseudo object associated
// with the Request. By default system exceptions are passed through the 
// Environment object.
//
// Valid values = 0 or 1

_CORBA_MODULE_VAR _core_attr CORBA::ULong outConScanPeriod;
//  Idle connections shutdown. The ORB periodically scans all the
//  incoming connections to detect if they are idle.
//  If no operation has passed through a connection for a scan period,
//  the ORB would treat this connection idle and shut it down.
//
//  Valid values = (n >= 0 in seconds) 
//                  0 --> do not close idle connections.

_CORBA_MODULE_VAR _core_attr timeValue clientCallTimeOutPeriod;
//   Call timeout. On the client side, if a remote call takes longer

_CORBA_MODULE_VAR _core_attr CORBA::Boolean supportPerThreadTimeOut;

//   1 means that after dispatching an upcall in thread pool mode, the

//
//  Valid values = 0 or 1

_CORBA_MODULE_VAR _core_attr CORBA::Boolean acceptBiDirectionalGIOP;
