Manually create a Database in an Existing Oracle 11g RAC - ASM - Grid Infrastructure

Objective: Manually create (through command line interface) an Oracle 11g RAC Database in an existing Oracle 11g Grid Infrastructure - ASM Environment. The new RAC database will be called "mani" and it will have 2 instances called "mani1" and "mani2".

Method Used: Create as a single instance standalone database in one node and then convert it into a RAC database running on a 2 node cluster.

Environment: Oracle 11g Grid Infrastructure, ASM, Oracle 11g RAC Database, 64 bit Oracle Linux Server 6.3, VMware Hypervisor ESXi 5.5

Existing RAC Setup: 2 nodes called "rac1" and "rac2", RAC database "babu" has 2 instances called "babu1" and "babu2" (currently shutdown). A shared disk / DISKGROUP to place the database files of the new database.

1) Start up the Cluster Resources in both nodes (if down)

In node 1, as "root" user

[oracle@rac1 ~]$ su root
Password:

[root@rac1 oracle]# . oraenv
ORACLE_SID = [oracle] ? +ASM1
The Oracle base has been set to /u01/app/oracle

[root@rac1 oracle]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

[root@rac1 oracle]# crsctl status resource -t

Repeat above in node 2 as well

2) We will be using the new DISKGROUP "DSK_GRP_02" (that we created previously) for the new database, so lets make sure its available in both nodes.
In node 1 as "oracle" user

[oracle@rac1 ~]$ . oraenv
ORACLE_SID = [oracle] ? +ASM1
The Oracle base has been set to /u01/app/oracle
[oracle@rac1 ~]$ sqlplus / as sysasm

SQL> ALTER DISKGROUP DSK_GRP_02 CHECK ALL;

Diskgroup altered.

SQL> ALTER DISKGROUP DSK_GRP_02 ADD DIRECTORY '+DSK_GRP_02/MANI';

Diskgroup altered

[oracle@rac1 ~]$ asmcmd ls -lt +DSK_GRP_02
Type Redund Striped Time             Sys Name
                                        N    MANI/
In node 2 as "oracle" user

[oracle@rac2 ~]$ . oraenv
ORACLE_SID = [oracle] ? +ASM2
The Oracle base has been set to /u01/app/oracle

[oracle@rac2 ~]$ asmcmd
ASMCMD> ls -l
State    Type    Rebal Name
MOUNTED EXTERN N      DATA/
MOUNTED EXTERN N      DSK_GRP_02/

3) In node 1 as "oracle" user, create necessary "oracle dump" directories, copy init.ora file from existing database (babu) and edit it:-

[oracle@rac1 ~]$ cd /u01/app/oracle/admin
[oracle@rac1 admin]$ mkdir mani
[oracle@rac1 admin]$ cd mani
[oracle@rac1 mani]$ mkdir adump
[oracle@rac1 mani]$ mkdir dpdump
[oracle@rac1 mani]$ mkdir hdump

Create "initmani1.ora" file by copying it from an existing database

[oracle@rac1 babu]$ cp /u01/app/oracle/admin/babu/pfile/init.ora.012014202025 $ORACLE_HOME/dbs/initmani1.ora

Content of edited "initmani1.ora" is as follows:-

audit_file_dest="/u01/app/oracle/admin/mani/adump"
audit_trail=none
# cluster_database=true
compatible=11.2.0.0.0
db_block_size=8192
db_create_file_dest="+DSK_GRP_02"
db_domain=localdomain
db_name="mani"
diagnostic_dest=/u01/app/oracle
dispatchers="(PROTOCOL=TCP) (SERVICE=maniXDB)"
memory_target=786432000
open_cursors=300
processes=150
remote_listener=rac-scan.localdomain:1521
remote_login_passwordfile=exclusive

mani1.instance_number=1
mani2.instance_number=2
mani1.thread=1
mani2.thread=2
mani1.undo_tablespace=UNDOTBS1
mani2.undo_tablespace=UNDOTBS2

4) Create password file

[oracle@rac1 babu]$ echo $ORACLE_BASE $ORACLE_HOME $ORACLE_SID
/u01/app/oracle /u01/app/oracle/product/11.2.0/dbhome_1 babu

[oracle@rac1 dbs]$ export ORACLE_SID=mani1
[oracle@rac1 dbs]$ echo $ORACLE_SID
mani1

[oracle@rac1 dbs]$ orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle

[oracle@rac1 dbs]$ ls -l
total 32
-rw-rw---- 1 oracle oinstall 1544 Feb 15 10:25 hc_babu1.dat
-rw-r----- 1 oracle oinstall   35 Jan 1 20:20 initbabu1.ora
-rw-r--r-- 1 oracle oinstall 555 Feb 15 11:03 initmani1.ora

11) In node 2 as "oracle" user, create necessary "oracle dump" directories and start up the database:-

[oracle@rac2 ~]$ . oraenv
ORACLE_SID = [oracle] ? babu
The Oracle base has been set to /u01/app/oracle
[oracle@rac2 ~]$ cd /$ORACLE_BASE/admin
[oracle@rac2 admin]$ mkdir mani
[oracle@rac2 admin]$ cd mani
[oracle@rac2 mani]$ mkdir adump
[oracle@rac2 mani]$ mkdir dpdump
[oracle@rac2 mani]$ mkdir hdump

[oracle@rac2 ~]$ echo $ORACLE_BASE $ORACLE_HOME $ORACLE_SID
/u01/app/oracle /u01/app/oracle/product/11.2.0/dbhome_1 mani2

[oracle@rac2 ~]$ sqlplus / as sysdba

-------------------- --------------------
mani2             rac2.localdomain
mani1             rac1.localdomain

Check the participating instances:-

SQL> select * from v$active_instances;
INST_NUMBER INST_NAME
----------- ------------------------------------------------------------
    1 rac1.localdomain:mani1
    2 rac2.localdomain:mani2

Also check the participating instances from node1:-

SQL> select * from v$active_instances;

INST_NUMBER INST_NAME
----------- ------------------------------------------------------------
          1 rac1.localdomain:mani1
          2 rac2.localdomain:mani2

2 rows selected.

SQL> col instance_name for a20
SQL> col host_name for a20
SQL> select instance_name,host_name from gv$instance;
INSTANCE_NAME        HOST_NAME
-------------------- --------------------
mani1                rac1.localdomain
mani2                rac2.localdomain

2 rows selected.

12) Add the new database in the cluster resource

- Shutdown the new database (both database instances)
- Cluster Resources in both nodes should be up and running

Perform the following from node1:-

[oracle@rac1 ~]$ su root
Password:
[root@rac1 oracle]# . oraenv
ORACLE_SID = [oracle] ? +ASM1
The Oracle base has been set to /u01/app/oracle
[root@rac1 oracle]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

[oracle@rac1 ~]$ . oraenv
ORACLE_SID = [oracle] ? babu
The Oracle base has been set to /u01/app/oracle
[oracle@rac1 ~]$ export ORACLE_SID=mani1
[oracle@rac1 ~]$ echo $ORACLE_SID $ORACLE_HOME $ORACLE_BASE
mani1 /u01/app/oracle/product/11.2.0/dbhome_1 /u01/app/oracle
[oracle@rac1 ~]$ srvctl add database -d mani -o $ORACLE_HOME -m localdomain
[oracle@rac1 ~]$ srvctl add instance -d mani -i mani1 -n rac1
[oracle@rac1 ~]$ srvctl add instance -d mani -i mani2 -n rac2

Check the status of new database:-

Objective: Below steps will explain how to manually add a shared disk, create and mount a DISKGROUP in ASM using the newly created shared disk.

Environment: Oracle 11g Grid Infrastructure, ASM, Oracle 11g RAC Database, 64 bit Oracle Linux Server 6.3, VMware Hypervisor ESXi 5.5

Existing RAC setup: 2 nodes called "rac1" and "rac2", RAC database "babu" has 2 instances called "babu1" and "babu2".

Hardware (VM) Configuration:

1) Follow Steps 4 through 17 in Section 2 of this link on how to create a Shared Disk.

OS / ASM Configuration:

2) In Node 1, connect as "root" and see if the newly added disk is visible:-

[root@rac1 oracle]# ls -l /dev/sd*
brw-rw---- 1 root disk 8, 0 Jan 20 13:19 /dev/sda
brw-rw---- 1 root disk 8, 1 Jan 20 13:19 /dev/sda1
brw-rw---- 1 root disk 8, 2 Jan 20 13:19 /dev/sda2
brw-rw---- 1 root disk 8, 16 Jan 20 13:19 /dev/sdb
brw-rw---- 1 root disk 8, 17 Jan 20 13:19 /dev/sdb1
brw-rw---- 1 root disk 8, 32 Jan 20 13:19 /dev/sdc

3) Create a new partition (in the new disk) using all available space as shown below:-

[root@rac1 oracle]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x7fb6e683.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-652, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-652, default 652):
Using default value 652

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

4) Once partition is created, list it to see if its visible:-

[root@rac1 oracle]# ls -l /dev/sd*
brw-rw---- 1 root disk 8, 0 Jan 20 13:19 /dev/sda
brw-rw---- 1 root disk 8, 1 Jan 20 13:19 /dev/sda1
brw-rw---- 1 root disk 8, 2 Jan 20 13:19 /dev/sda2
brw-rw---- 1 root disk 8, 16 Jan 20 13:19 /dev/sdb
brw-rw---- 1 root disk 8, 17 Jan 20 13:19 /dev/sdb1
brw-rw---- 1 root disk 8, 32 Jan 20 13:24 /dev/sdc
brw-rw---- 1 root disk 8, 33 Jan 20 13:24 /dev/sdc1

5) Create an ASM disk called "DISK2" using the newly partitioned/created disk:-

[root@rac1 oracle]# oracleasm createdisk DISK2 /dev/sdc1
Writing disk header: done
Instantiating disk: done

[root@rac1 oracle]# oracleasm scandisks
Reloading disk partitions: done
Cleaning any stale ASM disks...
Scanning system for ASM disks...

[root@rac1 oracle]# oracleasm listdisks
DISK1
DISK2

6) Switch to "oracle" user and start the existing database "babu":-

[root@rac1 oracle]# su oracle

[oracle@rac1 ~]$ . oraenv

ORACLE_SID = [+ASM1] ? babu
The Oracle base remains unchanged with value /u01/app/oracle

[oracle@rac1 ~]$ srvctl start database -d babu

[oracle@rac1 ~]$ . oraenv
ORACLE_SID = [babu] ? +ASM1
The Oracle base remains unchanged with value /u01/app/oracle

7) Connect to ASM instance 1 and check the mounted / participating ASM instances (optional step):-

[oracle@rac1 ~]$ sqlplus / as sysasm

SQL> select * from v$active_instances;

INST_NUMBER INST_NAME
----------- ------------------------------------------------------------
      1 rac1.localdomain:+ASM1
      2 rac2.localdomain:+ASM2

8) Verify if the new disk is visible from the ASM instance 1:-

SQL> SELECT MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,NAME,FAILGROUP,PATH,FAILGROUP_TYPE FROM V$ASM_DISK;

MOUNT_S HEADER_STATU MODE_ST NAME       FAILGROUP PATH                       FAILGRO
------- ------------ ------- ---------- ---------- -------------------------- -------
CLOSED PROVISIONED ONLINE                        /dev/oracleasm/disks/DISK2 REGULAR
CACHED MEMBER       ONLINE DATA_0000 DATA_0000 /dev/oracleasm/disks/DISK1 REGULAR

9) Create DISKGROUP using the new disk:-

SQL> CREATE DISKGROUP DSK_GRP_02
        EXTERNAL REDUNDANCY
        DISK '/dev/oracleasm/disks/DISK2';

Diskgroup created.

10) See if the new DISKGROUP is visible from the ASM instance:-

SQL> SELECT MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,NAME,FAILGROUP,PATH,FAILGROUP_TYPE FROM V$ASM_DISK;

MOUNT_S HEADER_STATU MODE_ST NAME             FAILGROUP       PATH                       FAILGRO
------- ------------ ------- ---------------- --------------- -------------------------- -------
CACHED MEMBER       ONLINE DSK_GRP_02_0000 DSK_GRP_02_0000 /dev/oracleasm/disks/DISK2 REGULAR
CACHED MEMBER       ONLINE DATA_0000        DATA_0000       /dev/oracleasm/disks/DISK1 REGULAR

11) As "root" user, check the status. You will see its online in node 1, but offline (not mounted) in node2:-

[root@rac1 oracle]# crsctl status resource -t
--------------------------------------------------------------------------------
NAME           TARGET STATE        SERVER                   STATE_DETAILS

               ONLINE ONLINE       rac1
               OFFLINE OFFLINE      rac2

12) In Node2, login as "oracle" user and verify the status of the newly created DISKGROUP:-

From database instance 2:-

[oracle@rac2 ~]$ . oraenv
ORACLE_SID = [oracle] ? babu
expThe Oracle base has been set to /u01/app/oracle
[oracle@rac2 ~]$ export ORACLE_SID=babu2
[oracle@rac2 ~]$ sqlplus / as sysdba

13) Login as "root" user, enable and mount the new diskgroup:-

[root@rac2 oracle]# srvctl enable diskgroup -g DSK_GRP_02
PRCC-1010 : DSK_GRP_02 was already enabled
PRCR-1002 : Resource ora.DSK_GRP_02.dg is already enabled

[root@rac2 oracle]# srvctl start diskgroup -g DSK_GRP_02

------------ -------------------- ----------- ---------- ----------
           1 DATA                 MOUNTED           3592       1332
           2 DSK_GRP_02           MOUNTED           5114       5021

From database instance 2:-

[oracle@rac2 ~]$ . oraenv
ORACLE_SID = [oracle] ? babu
expThe Oracle base has been set to /u01/app/oracle
[oracle@rac2 ~]$ export ORACLE_SID=babu2
[oracle@rac2 ~]$ sqlplus / as sysdba

Now the new diskgroup DSK_GRP_02 is ready for use.

Next step is to manually create a 11g RAC database and placing the database files in the newly created DISKGROUP.
