Oracle Database connection using Oracle Wallet

Oracle Wallet protects your oracle database user credential by password, it means, Oracle wallet creates a secured credential store, and sqlplus reads the credentials from the store to connect to specified database.

To use it, you need Oracle database client.


In $ORACLE_HOME/bin, mkstore can be found. If you prefer to GUI, type owm from unix console.

user: root
DB User: SCOTT
SID: TEST


1. Create .sqlnet.ora in /root with below entries

SQLNET.WALLET_OVERRIDE=TRUE
WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/root)))

2. Create Oracle Wallet in /root
# mkstore -create -wrl /root
Oracle Secret Store Tool : Version 11.2.0.1.0 - Production
Copyright (c) 2004, 2009, Oracle and/or its affiliates. All rights reserved.

Enter password:

Enter password again:

3. Add credentials
Syntax:  mkstore -wrl /root -createCredential <ORACLE_SID> scott

# mkstore -wrl /root -createCredential TEST scott
Oracle Secret Store Tool : Version 11.2.0.1.0 - Production

Your secret/Password is missing in the command line
Enter your secret/Password:

Re-enter your secret/Password:

Enter wallet password:

Create credential oracle.security.client.connect_string1
4. Verify the setting

# sqlplus /@TEST

Openldap Installation and Configuration on SuSE Linux 11

Use Yast(2) to install openldap server and client, I am using  version 2-2.4.26-0.12.1 in this case.

Installation

Here, I am not explain the installation in details.

1. Check LDAP, LDAP over SSL, and LDAP over IPC, if you are not using yast2, you might be able to change the options in ldap configuration files.

Configuration

base    dc=office,dc=goweekend,dc=ca
uri     ldap://ldap.office.goweekend.ca
surfix dc=office,dc=goweekend,dc=ca
Administrator DN cn=Administrator,dc=office,dc=goweekend,dc=ca



restart ldap service
# service ldap restart

Population

Add your own schema

Add your own schema if necessary, if not, you can skip this section to load your groups/users.

you can refer to /etc/openldap/schema/core.ldif to [rrepare your own schema. You can register your own OID from Internet Assigned Numbers Authority (IANA) by filling out the registration form http://pen.iana.org/pen/PenApplication.page, to check your existing OID number, go to page http://www.iana.org/assignments/enterprise-numbers/enterprise-numbers.

 Or, you can dump existing schema from your existing ldap server by following below procedure. For instance, mylocal.schema
Find the included schema in slapd.conf, and copy those entries to /var/tmp/dump.conf

include         /etc/openldap/schema/core.schema
include         /etc/openldap/schema/cosine.schema
include         /etc/openldap/schema/inetorgperson.schema
include         /etc/openldap/schema/rfc2307bis.schema
include         /etc/openldap/schema/yast.schema
include         /etc/openldap/schema/mylocal.schema

1. Login into a Linux server which can connect to existing ldap server
2. create /var/tmp/dump.conf
   include         /etc/openldap/schema/core.schema
   include         /etc/openldap/schema/cosine.schema
   include         /etc/openldap/schema/inetorgperson.schema
   include         /etc/openldap/schema/rfc2307bis.schema
   include         /etc/openldap/schema/yast.schema
   include         /etc/openldap/schema/mylocal.schema
3. create folder /var/tmp/schema_dump
   # mkdir -p /var/tmp/schema_dump
4. dump schema
   # slaptest -f /var/tmp/dump.conf -F /var/tmp/schema_dump
5.  copy the dump to new ldap server by scp, ftp ..., but I prefer tar and ssh
   # tar -cf - /var/tmp/schema_dump | ssh ldap.office.goweekend.ca "cd /; tar -xf -"
6. modify /var/tmp/schema_dump/cn=config/cn=schema/cn={5}mylocal.ldif on new ldap server
   

   From	to
   dn: cn={5}mylocal	,cn=schema,cn=config
   cn: {5}mylocal	mylocal

   
   and remove below entries from the end

   createTimestamp:
   entryCSN:
   modifiersName: cn=config

Oracle 10g: Reconfigure Enterprise Manager

Remove existing Enterprise Manager Configuration and Repository
$ emca -deconfig dbcontrol db -repos drop

Configure Enterprise Manager
$ emca -config dbcontrol db -repos create

If Enterprise Manager failed to start, Check the log file, and if it is certificate relater, try to unsecure enterprise manager

If existing Enterprise Manager is running, you need stop it first

$ emctl stop agent
$ emctl stop dbconsole

Sometime, the agent/dbconsole cannot be stopped properly, you have to find the process and kill them.

For example,

When you try to stop dbconsole, it says:
Stopping Oracle Enterprise Manager 10g Database Control ...
--- Failed to shutdown DBConsole Gracefully ---
failed.

but when you try to find dbconsole status, it reads:
Oracle Enterprise Manager 10g is not running.

try to start it, it reads:
An instance of Oracle Enterprise Manager 10g Database Control is already running.

but if you can find its port number, you can run below perl file to find out who is using the port number, and kill it.

below scripts is quoted from internet, and don't have the writer's name

Upgrade Oracle Database 10g to 11g

Prerequisites Check

Run the Pre-Upgrade Information Tool for Collecting Pre-Upgrade Information

Step 1
      Log in to the system as the owner of the Oracle Database 11g Release 2 (11.2) Oracle Home directory.
      Copy the Pre-Upgrade Information Tool (utlu112i.sql) from the Oracle Database 11g Release 2 (11.2) ORACLE_HOME/rdbms/admin directory to a directory outside of the Oracle Home, such as the temporary directory on your system.
      $ORACLE_HOME/rdbms/admin/utlu112i.sql
Step 2
      Change to the directory where utlu112i.sql had been copied in the previous step.
      Start SQL*Plus and connect to the database instance as a user with SYSDBA privileges. Then run and spool the utlu112i.sql file. Please note that the database should be started using the Source Oracle Home.
$ sqlplus '/ as sysdba'
SQL> spool upgrade_info.log
SQL> @utlu112i.sql
SQL> spool off
Check the spool file and examine the output of the Upgrade Information Tool.

Remove Public SYNONYM XMLCONCAT

$ sqlplus / as sysdba
SQL> select SYNONYM_NAME,OWNER from all_synonyms where SYNONYM_NAME = 'XMLCONCAT';
SQL> drop public synonym XMLCONCAT;
Synonym dropped.

Improve upgrade performance

To decrease the amount of downtime incurred when collecting statistics, you can collect statistics prior to performing the actual database upgrade. As of Oracle Database 10g Release 1 (10.1), Oracle recommends that you use the DBMS_STATS.GATHER_DICTIONARY_STATS procedure to gather these statistics. For example, you can enter the following:
$ sqlplus "/as sysdba"
SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;

Recompile Invalid Objects at least twice

$ cd $ORACLE_HOME/rdbms/admin
$ sqlplus "/ as sysdba"
SQL> @utlrp.sql

Upgrading

Starting Upgrade Using DBUA:
Enter the following command at a system prompt in the Oracle Database 11g Release 2 (11.2.0.x) environment:
Make sure that you are invoking the DBUA utility from the target Oracle home only .
Login as oracle user,
$ dbua

Follow the instructions in DBUA to finish upgrade without Upgrading Enterprise Manager, it will be reconfigured.

Post Upgrading

Change parameters for new Instance

mkdir -p /usr2/app/oracle/product/11.2.0.3/admin/<DBINSTANCE>/adump
mkdir -p $ORACLE_HOME/admin/<DBINSTANCE>/cdump
SQL> show parameter core_dump_dest
SQL> alter system set core_dump_dest='/usr2/app/oracle/product/11.2.0.3/admin/<DBINSTANCE>/cdump' scope=both;
SQL> show parameter audit
SQL> alter system set audit_file_dest='/usr2/app/oracle/product/11.2.0.3/admin/<DBINSTANCE>/adump' scope=spfile;
SQL> show parameter DB_RECOVERY_FILE_DEST
SQL> alter system set db_recovery_file_dest='/usr2/app/oracle/product/11.2.0.3/flash_recovery_area/<DBINSTANCE>' scope=both;
SQL> show parameter compatible;
SQL> ALTER SYSTEM SET COMPATIBLE = '11.2.0' SCOPE=spfile;

Change LOG_MODE

$ cd $ORACLE_HOME/dbs
$ orapwd file=orapw<DBINSTANCE> entries=10
$ sqlplus / as sysdba
SQL> SELECT LOG_MODE FROM SYS.V$DATABASE;
LOG_MODE
------------
NOARCHIVELOG

QL> shutdown immediate

Database dismounted.
ORACLE instance shut down.
SQL> startup mount

SQL> shutdown immediate
SQL> startup
