Hi

I am trying to install Oracle xe in Redhat Linux 5.3 ( Tikanga)

Oracle XE 11.2

I installed the user as root in RHEL.

The DB is up. I verified this using ps-ef | grep pmon

[oracle@localhost admin]$ ps -ef | grep pmon
oracle 5584 1 0 15:28 ? 00:00:02 xe_pmon_XE
oracle 20324 5108 0 17:27 pts/1 00:00:00 grep pmon


TNS listerner is up. I verified
[oracle@localhost admin]$ tnsping xe

TNS Ping Utility for Linux: Version 11.2.0.2.0 - Production on 08-APR-2014 17:26:24

Copyright (c) 1997, 2011, Oracle. All rights reserved.

Used parameter files:


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE)))
OK (10 msec)

But when i tried to login using sqlplus

[oracle@localhost admin]$ sqlplus

SQL*Plus: Release 11.2.0.2.0 Production on Tue Apr 8 17:28:05 2014

Copyright (c) 1982, 2011, Oracle. All rights reserved.

Enter user-name: system/smk@xe

This will be an issue with file ownership and access modes. Did you run your root.sh script? Set your umask correctly? Logon as a member of the OSDBA group? What is the ownership and modes of the oracle executable?

not Windows so above not relevant.
OS user should be member of "dba" group.

Hi
Issue resolved after adding the below in /etc/sysctl.conf
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576

Thanks for your response

Interesting. I can see no reason why those kernel parameters would have any effect on your problem. The issue you had appears to have been to do with launching server processes, and these parameters are for tuning the network and asynchronous I/O. I usually don't bother to change them from default.
But thankyou for the feedback.

I seriously doubt that values below had any impact on the connection failures.
