            To complete the definition of an IBM DB2 XAR, add the following values to the 
               		Open string field. Enclose values containing spaces in double quotes. 
               	 
            
 
            	 DB=name,UID=identifier,PWD=password,AXLIB=casaxlib
   [,SREG={T|F}]
   [,LOCALTX={T|F}][,ISOLEVEL={CR|RR|SZ|UR}][,ESLOGGING={0001|0002}]
   [,PACKAGEPATH=schema1[+schema2+...schemaN]] 
            	 Note: The open string format is defined by IBM. We strongly recommend that you become familiar with all of the available options
               by reviewing the 
               		DB2 Administration Guide and the 
               		Application Programmer's Guide in your IBM documentation. Example settings are shown in this topic for guidance only.

- The name of your DB2 database. 
                     			 
                  
- UID

- PWD

- AXLIB 
                     			 
                  
- The name of the library that contains the transaction manager's 
                     				ax_reg and 
                     				ax_unreg functions. 
                     				
                      
                        				   
                        					 
                        - For Windows: 
                           					 
                        
-  If the %PATH% environment variable includes the directory that contains the axlib library, set AXLIB to 
                           						CASAXLIB.dll. 
                           						
                            If the %PATH% environment variable does not include the directory that contains the axlib library, set AXLIB to include the
                              absolute path of the axlib library. For example, set AXLIB to either 
                              						  %COBDIR%\bin\CASAXLIB.dll (32bit) or 
                              						  %COBDIR%\bin64\CASAXLIB.dll (64bit). 
                              						
                            Note: In all cases, specification of the 
                              						  .dll file extension is optional.

-  If the $LD_LIBRARY_PATH or $LIBPATH environment variable includes the directory that contains the axlib library, set AXLIB
                           to either 
                           						casaxlib.so or 
                           						casaxlib64.so. 
                           						
                            If the $LD_LIBRARY_PATH or $LIBPATH environment variable does not include the directory that contains the axlib library,
                              set AXLIB to include the absolute path of the axlib library. For example, set AXLIB to either 
                              						  $COBDIR/lib/casaxlib.so (32bit) or 
                              						  $COBDIR/lib/casaxlib64.so (64bit). 
                              						
                            Note: In all cases, specification of the 
                              						  .so file extension is required. 
                              						
                            
 
- SREG 
                     			 
                  
-  Static Registration flag (optional). To register the XA switch module statically, you must set 
                     				SREG=T. Set 
                     				SREG=F or do not specify SREG to omit static registration (Default).
