4. Steps to Configure Oracle Sharding
Nodes/Hosts
Step Details 1
shardcat/Shard1/Shard2
Install Oracle Software Only 12cR2 – Preferably Same Location 2
shardcat
Create Database SCAT using DBCA (NON CDB) 3
Install GSM Software as Separate Home 4
Create Environment Setup 5
Shardcat
Prepare SCAT database for Sharding - Prerequisities 6
Configure Shard Catalog using GSDCTL – Create Shard Catalog in SCAT 7
shard1/shard2
Start the SCH Agent & Register Shard nodes to SCAT database 8
Create Shard Group/Director/Add Shards 9
Deploy Shards using GSDCTL – This will eventually create databases in shard1/shard2 10
Verify Shard Configuration 11
Create Global Service using GSDCTL 12
Create sample schema and Tablespace set and see that propagate to shard1/shard2 13
Connect to sample schema and create shard table 14
Shardcat/shard1/shard2
Verify the sample table is created across shards

5. Step 1 : Install Oracle 12c R2 Software
Install Oracle 12cR2 Software on all three nodes shardcat/shard1/shard2
Complete Pre-requisities
Install with Software only option
Sample options to change in <softwarelocation>/response/db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY ORACLE_HOSTNAME=Geek DBA11g UNIX_GROUP_NAME=oinstall INVENTORY_LOCATION=/u02/app/oraInventory ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_1 ORACLE_BASE=/u01/app/oracle oracle.install.db.InstallEdition=EE oracle.install.db.DBA_GROUP=dba oracle.install.db.OPER_GROUP=oper oracle.install.db.BACKUPDBA_GROUP=dba oracle.install.db.DGDBA_GROUP=asmadmin oracle.install.db.KMDBA_GROUP=dba SECURITY_UPDATES_VIA_MYORACLESUPPORT=false DECLINE_SECURITY_UPDATES=true
Create Oracle Home Directories
mkdir -p /u01/app/oracle/product/12.1.0/db_1
mkdir -p /u02/app/oraInventory chown -R oracle:oinstall /u02/app/oraInventory
Sample Run Installer Command
./runInstaller -silent -ignoresysprereqs -responsefile /home/oracle/database/response/db_install.rsp

6. Step 2: Create ShardCatalog Database
On shardcat Node:-
Create Directories
mkdir –p /u01/app/oracle/flash_recover_area/SCAT
mkdir –p /u01/app/oracle/fast_recovery_area/SCAT
mkdir –p /u01/oradata/SCAT
mkdir –p /u01/app/oracle/admin/SCAT/adump
Run DBCA
./dbca -silent \
-createDatabase \
-templateName General_Purpose.dbc \
-gdbName SCAT \
-sid SCAT \
-SysPassword ****\
-createAsContainerDatabase false\
-SystemPassword ***\
-emConfiguration NONE\
-redoLogFileSize \
-recoveryAreaDestination /u01/app/oracle/SCAT \
-DatafileDestination /u01/app/oracle/SCAT
-storageType FS \
-listeners LISTENER12 \
-registerWithDirService false \
-characterSet AL32UTF8 \
-nationalCharacterSet AL16UTF16 \
-databaseType MULTIPURPOSE \
-memoryPercentage 40 \
-memoryType AUTO

7. Step 3: Install GSM Software in Shardcat
On Shardcat Node:-
Download from Oracle Downloads page or Edelivery.oracle.com
Unzip the GSM Software
Install as separate Home

8. Step 4: Create Environment Setup in Shardcat

9. Step 5 : Prepare SCAT database for Sharding - Prerequisities
On Shardcat : SCAT Database
alter system set db_create_file_dest='/u01/ora12c/app/oracle/oradata' scope=both;
alter system set open_links=16 scope=spfile;
alter system set open_links_per_instance=16 scope=spfile;
startup force
alter user gsmcatuser account unlock;
alter user gsmcatuser identified by oracle;
CREATE USER mygdsadmin IDENTIFIED BY oracle;
GRANT connect, create session, gsmadmin_role to mygdsadmin;
grant inherit privileges on user SYS to GSMADMIN_INTERNAL;
execute dbms_xdb.sethttpport(8080);
commit;
@?/rdbms/admin/prvtrsch.plb
exec DBMS_SCHEDULER.SET_AGENT_REGISTRATION_PASS('oracleagent');

10. Step 6:– Create Shard Catalog in SCAT
On Shardcat node, in SCAT Database & Set environment to GSM Home # gdsctl GDSCTL> create shardcatalog -database shardcat:1521:SCAT -chunks 12 -user mygdsadmin/oracle -sdb SCAT -region region1 GDSCTL>add gsm -gsm sharddirector1 -listener pwd oracle -catalog shardcat:1521:SCAT -region region1 GDSCTL>start gsm -gsm sharddirector1 GDSCTL>add credential -credential oracle_cred -osaccount oracle -ospassword **** GDSCTL> exit

11. Step 7: Start the Scheduler Agent on Shard Nodes
Scheduler Agent is already installed if you install oracle database software just start it
#Set Oracle Home
#schagent start
#schagent status
# echo oracleagent | schagent –resiterdatabase shardcat 8080  provide name of host not database

12. Step 8 : Create Shard Group/Director/Add Shards
GDSCTL>set gsm -gsm sharddirector1
GDSCTL>connect mygdsadmin/oracle
Catalog connection is established
GDSCTL>-- add shard group
GDSCTL>add shardgroup -shardgroup primary_shardgroup -deploy_as primary -region region1
The operation completed successfully
GDSCTL>-- add shard1
GDSCTL>add invitednode shard1
GDSCTL>create shard -shardgroup primary_shardgroup -destination shard1 -credential oracle_cred
DB Unique Name: sh1
GDSCTL> --add shard2
GDSCTL>add invitednode shard2
GDSCTL>create shard -shardgroup primary_shardgroup -destination shard2 -credential oracle_cred
DB Unique Name: sh2

13. Step 8 : Deploy Shards In shardcat node, using gsdctl, run
gsdctl> deploy
Note: This will create the databases in shard1 and shard2 using dbca and create listeners automatically

14. Step 10: Verify Shard Status

15. Step 11 : Create Global Service using GSDCTL
Using GDSCTL on shardcat gdsctl> add service –service test_srv –role primar
gdsctl> config service
gdsctl> start service
gdsctl> status service

16. Step 12: Create sample schema and Tablespace set and see that propagate to shard1/shard2
~]$ db_env Sqlplus / as sysdba alter session enable shard ddl; create user app_schema identified by oracle; grant all privileges to app_schema; grant gsmadmin_role to app_schema; grant select_catalog_role to app_schema; grant connect, resource to app_schema; grant dba to app_schema; grant execute on dbms_crypto to app_schema; #Create Sharded Tablespace & Test out conn app_schema/oracle CREATE TABLESPACE SET TSP_SET_1 using template (datafile size 100m extent management local segment space management auto ); CREATE TABLESPACE products_tsp datafile size 100m extent management local uniform size 1m; Note: For any command that need to be shard, you must enable shard ddl at session level before running the sql command

17. Step 13: Create Shard Tables

18. Step 14: Verify Distribution of Tables to shards
On Shard Catalog SDB Database

19. Step 14: Verify Distribution of Tables to Shards
On Shard1, SH1 database the customer table is partitioned and some of the partitions created here
On Shard2, SH2 database the customer table is partitioned and some of the partitions created here
