CORBA 2.6.1 Programmer's Guide for C++

max_threads number
The maximum number of servant threads available in a process. Default is 4097. The effective maximum number of threads in a server
depends on the size of each thread's stack and the number of NSK threads available in a CPU.
nsdom_ir file-name
Default is $NSD_ROOT/etc/nsdom.ir.
stack_size number
Default is 65536. Minimum is 16384 and maximum is 32768000. This setting dictates the size of thread stacks.
keep_alive {true | false}
Controls whether the TCP/IP keep-alive mechanism is enabled. Default is true. If enabled, TCP will periodically ping the other end of a
connection to determine if the connection is still valid, which will detect if the other end has gone away, even if no data is being
transferred. This variable is useful when one side is waiting for data (the next request for a server, or a reply for a client) and the other
side fails.
giop_version version
Allows you to select the ORB giop version for both the client and server directions. The key values are 1.0, 1.1, and 1.2. The default is
version 1.2. The key sets the ORB’s GIOP version. IORs generated by this ORB will have this version and GIOP requests will have a
version that is the minimum of this version and the remote IOR's version.
allow_wchar_wstring_in_1_0 {true | false}
Controls whether wchar and wstring are enabled over GIOP 1.0. The key is allow_wchar_wstring_in_1_0, and the key value is true or
false. The default is false. Since the default is false, you must set this configuration value if you want NonStop CORBA to allow wchar
and wstring to be transmitted over GIOP 1.0. Many vendors, including NonStop CORBA 2.3 B13, allow wchar and wstring to be
transmitted over GIOP 1.0. NonStop CORBA also allows wchar and wstring to be transmitted over GIOP 1.0. If the
allow_wchar_wstring_in_1_0 key value is set to false, marshalling exceptions are thrown if GIOP 1.0 is in effect. If the
allow_wchar_wstring_in_1_0 key value is set to true, marshalling exceptions are not thrown if GIOP 1.0 is in effect.
wchar_native_code_set code set
Controls whether the C11 C++ ORB publishes UCS-2 or UTF-16 as its wide character native code set. The key is
wchar_native_code_set, and the key value is UCS-2 or UTF-16. The default is UCS-2. Interoperation with IONA E2A ASP 5.1 (or any
other ORB that implements UCS-2 incorrectly) is the only reason to use UTF-16. IONA has fixed their handling of wstring endian-ness in
ASP 6.0, so UTF-16 is only required for ASP 5.x.
