many local sessions

Hi guys!
I don't understand how to avoid that error. Could you help me please. Of course I can read 'Action' but I have no idea what to do exactly.
Thank you

-----------------------------
ORA-02045 too many local sessions participating in global transaction
Cause: There are too many sessions at this site to accommodate this transaction.
Action: Use an existing database link so that another session need not be created at the remote site.

Make changes to these parameters in your init.ora file. BTW what is your oracle version? Always include the version of ORACLE AND THE OS

MAX_TRANSACTION_BRANCHES = 32
open_links = 100
distributed_transactions= 100

These changes require a bounce on the instance.

Sorry,
Oracle 8.17, RedHat 6.2
Thank you

As I can see this parameter MAX_TRANSACTION_BRANCHES initialization parameter has been made obsolete,
so I have to use this one
_MAX_TRANSACTION_BRANCHES = 32
Thank you

MAX_TRANSACTION_BRANCHES = 32
is obsolete if the oracle is 8.1.6 or higher
