Create Control File

I keep forgetting the syntax for create control file, thought it would help me and others for the syntax and the steps to create.

STEPS:

1. Shutdown the database
2. sqlplus '/as sysdba'
3. startup nomount
4. Create Control file (syntax below)
5. alter database open

CREATE CONTROLFILE REUSE DATABASE "anydatabasename" NORESETLOGS NOARCHIVELOG
MAXLOGFILES 50
MAXLOGMEMBERS 3
MAXDATAFILES 1000
MAXINSTANCES 8
MAXLOGHISTORY 500
LOGFILE
GROUP 1 'REDLOG PATH' SIZE 10M,
GROUP 2 'REDLOG PATH' SIZE 10M
DATAFILE
;


EXAMPLE:

CREATE CONTROLFILE REUSE DATABASE "PROD" RESETLOGS NOARCHIVELOG
MAXLOGFILES 50
MAXLOGMEMBERS 3
MAXDATAFILES 1000
MAXINSTANCES 8
MAXLOGHISTORY 500
LOGFILE
GROUP 1 '/APPS/proddata/log01a.dbf' SIZE 10M,
GROUP 2 '/APPS/proddata/log02a.dbf' SIZE 10M
DATAFILE
'/APPS/proddata/a_txn_data01.dbf' ,
'/APPS/proddata/a_txn_data02.dbf' ,
'/APPS/proddata/a_txn_data03.dbf' ,
'/APPS/proddata/a_txn_ind01.dbf' ,
'/APPS/proddata/a_txn_ind02.dbf' ,
'/APPS/proddata/a_txn_ind03.dbf' ,
'/APPS/proddata/a_txn_ind04.dbf' ,
'/APPS/proddata/a_txn_ind05.dbf' ;


If you want to set a new SID for the database then use SET instead of REUSE.
If you want to reset redo logs which will be ideal for a cloned database out of a cold backup.

'Linux-x86_64 Error: 28: No space left on device' While trying to start the database -- Error

SQL> startup mount pfile='/tmp/initdlfasp12.ora'
ORA-27102: out of memory
Linux-x86_64 Error: 28: No space left on device


This as you can see is on Linux x86 with 64 bit processor. We got this error after we changed SGA on 10gR2 database. So was sure that this is something to do with the OS.

Parameters to check for this are shmall.

shmall is the total amount of shared memory, in pages, that the system can use at one time.

$cat /proc/sys/kernel/shmmax
53687091200

$ getconf PAGE_SIZE
4096

As per Oracle SHMALL should be set to the total amount of physical RAM divided by page size.

Our system has 64GB memory, so change kernel.shmall = 1024 * 1024 * 1024 * 64 / 4096 = 16777216


Once this value is calculated you can modify Linux system configuration file directly.

$ su - root
vi /etc/sysctl.conf file:
kernel.shmall=16777216

and

# sysctl -p

Once this is done the database was started without any problem.
