Previous tasks to perform before start practicing with Oracle Spatial

Training material

Important:

This guide is intended to be use with either Oracle 12c Multitenant environment or Oracle Pre-12c

Non-Container (also works with 11gR1 – R2).

Most of the tasks are optional, however those ones that are optional are marked with an (*) , the

ones that are mandatory were tagged with the legend “Mandatory”.

Please follow the order of this task, skip the optional ones as needed.

1. Change in the .bash_profile

In order to use SecureShell client we need to introduce the support of DELETE key into the

bash_profile, therefore at the end of the file we must add the following:

This should be bash_profile after this change:

2. Creating an after startup trigger (Only if you have a Multi-Tenant Container DB)

In a CDB environment, the default behavior when a CDB is started is that all user-defined PDBs are

in MOUNTED state i.e. closed. The only way to change this behavior is by using an AFTER STARTUP

trigger on the database.

In this exercise, you will create AFTER STARTUP trigger to open all PDBs of a CDB. The AFTER

stty erase ^H

# Oracle Settings

export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_HOSTNAME=db.oracledemo.com

export ORACLE_UNQNAME=cdborcl

export ORACLE_BASE=/u01/app/oracleexport ORACLE_HOME=$ORACLE_BASE/product/12.1.0.2/db_1

export ORACLE_SID=cdborcl

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlibstty erase ^H

STARTUP trigger is a database event trigger, which means that the user creating the trigger should

have ADMINISTER DATABASE TRIGGER system privilege. The trigger will only fire after the startup

event on the database.

Steps

1.

Connect to the Root container of CDBORCL as a SYSDBA user.

2. Create a trigger in CDBORCL to open all PDBs automatically after starting upCDBORCL.

3.

Restart the database CDBORCL.

4.

Observe that the PDBs are in READ WRITE open mode.

3. Configuring DB parameters, (this applies to Container and Non-Container DB)

1.

Modify the DB_CACHE_SIZE database initialization parameter to be at least 75 MB.Notice that this parameter will apply either to the Container and all the PDBs.

a.

sqlplus system/Manager1;b.

SHOW PARAMETER db_cache_size

2.

If the db_cache size is less than 75M (megabytes) type:

a. ALTER SYSTEM SET db_cache_size=75M scope=spfile;b. shutdown;c.

startup;d. SHOW PARAMETER db_cache_sizee. exit

. oraenv [Enter cdborcl at the prompt]

sqlplus / as SYSDBA

CREATE OR REPLACE TRIGGER AFTER_STARTUP AFTER STARTUP ONDATABASE BEGIN EXECUTE IMMEDIATE 'ALTER PLUGGABLE DATABASE ALLOPEN'; END AFTER_STARTUP; / SHOW ERRORS;

SHUTDOWNIMMEDIATE;

SELECT CON_ID, NAME, OPEN_MODE FROM V$PDBS;


5/18


This is the expected output:

4. Create additional database tablespaces (applies to Container and Non-Container

DB) Mandatory

In SQL*Plus, assuming you are connected as system user, run the following statements:

In Multi-Tenant Container instance:

Be sure your current container is PDBORCL


ALTER SESSION SET CONTAINER=PDBORCL;

COLUMN NAME FORMAT A8;

SELECT NAME, CON_ID, DBID, CON_UID, GUIDFROM V$CONTAINERS ORDER BY CON_ID;


6/18


Option A. Using a Single-Tenant instance:

Option B . Using a Non-container Single Instance (Pre-12c):

5. Create the Oracle database users and grant appropriate privileges. Mandatory

Assuming you are still logged in as system/Manager1 either in the Non-container single-instance

or into the Pluggable DB (PDBORCL)

In Single-Tenant Container instance:

Be sure your current container is PDBORCL and also it is open:

Execute the following:

create tablespace student datafile'/u01/app/oracle/oradata/cdborcl/pdborcl/student.dbf' size 150M;

create tablespace indx_tblspc datafile'/u01/app/oracle/oradata/cdborcl/pdborcl/indx_tblspc.dbf' size150M;

create tablespace work_indx_tblspc datafile'/u01/app/oracle/oradata/cdborcl/pdborcl/work_indx_tblspc.dbf'size 100M;

create tablespace student datafile 'student.dbf' size 150M;

create tablespace indx_tblspc datafile 'indx_tblspc.dbf' size150M;

create tablespace work_indx_tblspc datafile 'work_indx_tblspc.dbf'size 100M;

ALTER SESSION SET CONTAINER=PDBORCL;

SHOW CON_ID;SHOW CON_NAME;

ALTER PLUGGABLE DATABASE OPEN;

6. Connecting to the instance with student user

After creating the user student , the only way to connect in a multi-tenant environment is through

EZCONNECT, since we haven’t created the SERVICE yet, we are able to connect as follows:


create user student identified by student default tablespacestudent;

grant connect, resource to student;

alter user student quota unlimited on student;

$sqlplus student/student@//[HOSTNAME|IP ]:1521/pdborcl

7. Configuring Services to allow external connections to the Pluggable DB.

Mandatory.

When a PDB is created, a new default service for the PDB is created automatically, and has

the same name as the PDB. You cannot manage this service, and it should only be used for

administrative tasks.

Do not use this default PDB service for applications. Always use user-defined services for

applications because you can customize user-defined services to fit the requirements of your

applications.


9/18


You can create, modify, or remove a service with a PDB property in the following ways:

If the database is not being managed by Oracle Restart or Oracle Clusterware, then use

the DBMS_SERVICE package to create or remove a database service. This is the

method you will follow in this task.

Note: Each database service name must be unique in a CDB, and each database service

name must be unique within the scope of all the CDBs whose instances are reached through a

specific listener.

Steps

1. When you create a service using the DBMS_SERVICE package, the PDB property of the newservice is set to the current container. Therefore, login to the PDB that you want tocreate/modify/delete the user-defined services before running the DBMS_SERVICE procedures.

If you run DBMS_SERVICE.CREATE_SERVICE in the root container then the service is associatedwith the root.

Connect as SYS to PDBORCL with the SYSDBA role.

2. Create the service by the name PORCL using the DBMS_SERVICE.CREATE_SERVICE procedure.

3. Check to see if the newly created PORCL service shows up in V$SERVICES.

At this point this is the expected output:

CONNECT SYS/Manager1@//127.0.0.1:1521/PDBORCL ASSYSDBA;SELECT CON_ID, NAME, OPEN_MODE FROM V$PDBS;

EXEC DBMS_SERVICE.CREATE_SERVICE (SERVICE_NAME=>'PORCL', NETWORK_NAME=>'PORCL');

SELECT NAME FROM V$SERVICES;


10/18


4. Start the newly created PORCL service using DBMS_SERVICE.START_SERVICE procedure.Check if the newly created service is started using the V$SERVICES view, and also in the listenerservices.

5. Reconnect to PDBORCL using the PORCL service. Verify that you are reconnected back toPDB PDBORCL.

6. Now connect with the student user:

EXEC DBMS_SERVICE.START_SERVICE('PORCL');SELECT NAME, PDB FROM V$SERVICES;

HOST lsnrctl services

CONNECT SYS/oracle@//127.0.0.1:1521/PORCL AS SYSDBA;SELECT CON_ID, NAME, OPEN_MODE FROM V$PDBS;

Once he have configured the SERVICE , we must configure clients to use this SERVICE.

In our VM we must run NETCA in order to create a SERVICE entry within TNSNAMES.ORA

In a terminal window logged with the user oracle , run the command NETCA.

sqlplus student/student@//127.0.0.1:1521/PORCL;


12/18


Select “Local Net Service Name Configuration”

Please proceed with the next steps inside NETCA by choosing the same options as follows:


13/18


Pleas provide a SERVICE NAME for PDBORCL.


14/18


Please provide your hostname name or IP.


15/18


Click on Change Login in order to provide a different user/password.


16/18



17/18


Please write the short name of the SERVICE_NAME.


18/18


Now we should close NETCA window, and connect from SQLPLUS with the user student as shown

below:

From now we can connect to PDBORCL as if we were using a Pre-12c Non-Container DB.
