ORA-29702, how to resolve?

[nekocat]

My environment:
RDBMS Version: 8.1.7.4
Operating System and Version: Tru64 4.0F

In my OPS environment (two nodes), the error ORA-29702 will often prompt. It will be triggered when doing import, export, simple sql statement like insert, update, create package, create trigger, etc.

Everytime this error is encountered, an trace file will be logged. Following is a sample:

/oracle/admin/abcde/udump/ora_12425.trc
Oracle8i Enterprise Edition Release 8.1.7.4.0 - Production
With the Partitioning and Parallel Server options
JServer Release 8.1.7.4.0 - Production
ORACLE_HOME = /oracle/product/8.1.7
System name: OSF1
Node name: abc
Release: V4.0
Version: 1229
Machine: alpha
Instance name: def
Redo thread mounted by this instance: 1
Oracle process number: 26
Unix process pid: 12425, image: oracle@abc (TNS V1-V3)

*** SESSION ID31.426) 2002-10-23 19:29:35.167
kjfmsgr: the master member (1) does not exist

The process id 12425 is actually the child process forked by sqlplus session creating this error.

What can I do to resolve this?

Thanks.
