It is well known thing and you can even find it on MOS, but I have a little more simple script for it, so I want to show little example.

First of all we need to start script on local database:

SQL>                                                                                                                                                                   
SQL> @transactions/global.sql
Enter filters(empty for any)...
Sid           :
Globalid mask :
Remote_db mask:

 INST_ID  SID    SERIAL# USERNAME REMOTE_DB REMOTE_DBID TRANS_ID         DIRECTION   GLOBALID                                           EVENT                      
-------- ---- ---------- -------- --------- ----------- ---------------- ----------- -------------------------------------------------- ---------------------------
       1  275       4469 XTENDER  BAIKAL     1742630060 8.20.7119        FROM REMOTE 4241494B414C2E63616336656437362E382E32302E37313139 SQL*Net message from client
                                                                                                                                                                  

Then we need to copy GLOBALID of interested session and run script on database that shown in column REMOTE_DBID, but with specifieng GLOBALID:

SQL>                                                                                                                                                                                                 
SQL> conn sys/syspass@baikal as sysdba
Connected.

======================================================================
=======  Connected to  SYS@BAIKAL(baikal)(BAIKAL)
=======  SID           203
=======  SERIAL#       38399
=======  SPID          6536
=======  DB_VERSION    11.2.0.4.0
======================================================================

SQL> @transactions/global.sql
Enter filters(empty for any)...
Sid           :
Globalid mask : 4241494B414C2E63616336656437362E382E32302E37313139
Remote_db mask:

INST_ID   SID    SERIAL# USERNAME  REMOTE_DB  REMOTE_DBID TRANS_ID   DIRECTION   GLOBALID                                            STATE                     
------- ----- ---------- --------- ---------- ----------- ---------- ----------- --------------------------------------------------  --------------------------
      1     9      39637 XTENDER   BAIKAL      1742630060 8.20.7119  TO REMOTE   4241494B414C2E63616336656437362E382E32302E37313139  [ORACLE COORDINATED]ACTIVE

It’s quite simple and fast.
