Operating Systems HP-UX Database replication process stopped in server Post 302979322 by anaigini45 on Friday 12th of August 2016 09:33:31 AM

Database replication process stopped in server

Hi,

A database (Oracle) replication process was executed by the DBA team in one server (serverX). However, this replication process gets terminated, and there are no errors in the replication log. But there is error in the OS log files (syslog.log) :

Code:
Aug  8 16:51:47 L28dre02 sshd[10388]: subsystem request for sftp 
Aug  8 17:11:15 L28dre02 vmunix:
Aug  8 17:11:15 L28dre02 vmunix: Pid 11582 was killed due to failure in 
writing the signal context- possible stack overflow.
Aug  8 18:45:31 L28dre02 sshd[17209]: Accepted keyboard-interactive/pam 
for oracle from 192.168.29.23 port 50190 ssh2

From the error "stack overflow", I found that the solution was to edit the value of the parameter 'PTHREAD_DEFAULT_STACK_SIZE'.
However, I am not sure how/where to locate the file in the server.

Another article I read says that change that parameter value in the file :
$SYBASE/RAX-15_5/bin/ra.sh

However, when I run echo $SYBASE in the server to look for the path, the error is :

Code:
L28dre02:/home/oracle:INTDB> echo $SYBASE
sh: SYBASE: Parameter not set.
L28dre02:/home/oracle:INTDB>

How do I locate this parameter and change the value?

***The replication application used is 'DBVisit'.
