ORA-03106 fatal two task communication error

[riverlee]

When I Logon Oracle(8.1.6) with DOA or PLSQLDEV,
I am getting the following error message
"ORA-03106 fatal two task communication error" but Oracle(7.3.2) no error.
Can anyone please give the solution so that I can proceed.

sql*net version 2.3

What happens if you connect with SQL*Plus 3.3 from your SQL*Net 2.3 home?

I have found the problem. Because in my oracle client dir "$ORACLE_HOME\nlsrtl32"
*.NLB files lost these files:
Lx20354.NLB Lx4001C.NLB
Lx40018.NLB Lx4002E.NLB
Lx40019.NLB Lx4002F.NLB
Lx4001A.NLB Lx40030.NLB
Lx4001B.NLB Lx40031.NLB
copy these from other computer.
That's OK!
Because I want thinnest Oracle Client,I cleaned up the Oracle Client.
With Oracle8,these files is needed!
Thank you!
