Oracle Database Timezone Issue

Problem:

Post changes in Linux system timezone (in /etc/sysconfig/clock file ) from ZONE="America/New York" to ZONE="Asia/Kolkata" systimetamp over the DB link or TNS alias started reflecting old/wrong timezone 

sqlplus <username>@<TNS_Alias>/<password>;

SQL> select systimestamp,current_timestamp from dual;

SYSTIMESTAMP                            CURRENT_TIMESTAMP
-----------------------------------     -------------------------------------------

Here , +05:30 was the correct time-stamp for Timezone "Asia/Kolkata"

Analysis:

It was identified that time zone of the database server was not matching with one of the Data guard setup in Linux zone configuration file /etc/sysconfig/clock

Required ZONE="Asia/Kolkata" 
But found ZONE="America/New York"

statspack report hangs

Problem: Statspack report hangs 

Executing @?/rdbms/admin/spreport.sql report hangs in midway & unable to proceed further until cancelled

Even if we try to keep it for Hours after undo_retention limit it will throw "ORA-01555 snapshot too old" & come out

Such issue is observed in pre-10g databases where there is no other substitute to stats-pack & its due to huge db object count

Analysis:

Initial analysis,  i kept the report running for over night & it kicked me out with ORA-01555 error after 9 Hours

Further , PERFSTAT.STATS$SQL_SUMMARY table found to be the problem causing table which was doing "db file sequential read" infinitely

Oracle Case insensitive search

Data entered in table column could be in different cases lower/upper making it difficult for search operation to retrieve all possible matches from the table

e.g.  To search abcd from the table if you enter Abcd as input string or anything that does not match with cases in which data is stored will result in “no rows selected” & vice versa.

Suppose case table has below rows, each one with different case but similar string

SQL> select * from case;

TEXT

--------------------------------------------------------------------------------

Abcd

aBcd

abCd

abcD

abcd

ABCD

6 rows selected.

bypass password prompt in shell

This blog will help you in bypassing or ignoring the password prompt in shell along with a sample script to test direct login to remote servers without any interruption due to password prompt

Using ssh –o & trap signals it is possible to skip password prompt & move ahead in the script

Although remote server direct login is enabled using public key sometimes it does not work either due to password policy expiring the password or server un-reachability. In both situation password will be prompted like below

$ssh oracrmdevlab hostname

oralab@oracrmdevlab's password:

Script:

Sample script has been written to provide report of the failure direct remote login from jump server for a particular osuser.

#!/bin/sh

set -x

BASE="/export/home/oralab/direct_login"

SCP_USER=`who -m | awk '{ print $1}'`

DT=`date '+%b_%d_%Y_%HH_%MM'`

DAT=`date '+%b_%Y'`

MAIL="oralab@xyz.com"

TODAY=`/bin/date +%d | cut -d"0" -f2` ; export TODAY

password reset in shell script using passwd

Resetting Password is a tedious job of the sys admin’s or DBA’s while managing over 100’s of servers.

Automatic password reset could make your job easier , What if your OS password gets reset automatically before expiry & reaches to your mailbox ? yes this is what came in my mind before I started hunting for the

Question How to reset password using passwd command in shell script?

While executing passwd command it takes three input i.e. Old password , New Password , New Password (confirmation)

It would have been difficult to pass these inputs to passwd prompts whithin shell without “expect” command

read –p command asks value by prompting for manual input but expect prompts as well as accepts input values in one go

expect can be configured to send the requested input value to desired command

expect is present in Linux by default but need to install it in rest of the Unix environment 

Script: expect.sh

#!/usr/bin/expect

set pwd [lindex $argv 0]

set pwd1 [lindex $argv 1]

set pwd2 [lindex $argv 2]

spawn /usr/bin/passwd

sleep 5

expect "UNIX password:"

sleep 5

send "$pwd\r"

sleep 5

expect "New password:"

sleep 5

send "$pwd1\r"

sleep 5

expect "Retype new password:"

sleep 5

send "$pwd2\r"

sleep 5

expect eof exit

Oracle 10g RAC Upgrade Lessons

Blog highlights basic steps to upgrade oracle 10g RAC db from 10.2.0.4 to 10.2.0.5 along with obstacles faced & Solution. 

 Systems:

Racdb1/Racdb2 ~ Sun OS 5.10 ~ Oracle 10204 ~ ASM ~ Primary

Racdbdr1/Racdbdr2 ~ Sun OS 5.10 ~ Oracle 10204 ~ ASM ~ Standby

 Activity: To Apply 10.2.0.5 Patch (8202632) + CRS PSU Jan 2011 (9952245) + RDBMS PSU JUL 2011 (12419392) to existing 10.2.0.4 oracle & cluster binaries

 Activity Sequence:

Upgrading 10g RAC from 10204 to 10205 involves below basic steps which needs to be performed on both primary & DR setups sequentially

  1.       Per-activity checks

ORACLE_HOME/ORA_CRS_HOME/oraInventory/OCR backup

Invalid Object/Index, backup status, datafile file status

Opatch version verification, current patchset

  2.       Differing archive sync

Racdb1/Racdb2 primary archive deferred with standby Racdbdr1/Racdbdr2
