Starting and Stopping Database on Windows


Go to Control Panel --> Administrative Tools --> Click on Services icon.

This will open a window show below.

Here scroll down to names starting with alphabet O check for anything starting with Oracle.

Observe the screenshot and look at Startup Type, for all the service names starting with Oracle Startup Type is set to Automatic except one. This means that everytime you restart your windows database restarts automatically. This is why you feel your windows has gone slow after installing the database.

Now right click on each of the Oracle Service and Click
on properties and you will see a window like below.

Here, change the Startup Type from Automatic to Manual and click OK.

After this, when ever you restart your database you will have to manually start the database. Open services, if you have installed only one Oracle database on your windows then if your database name is ORCL then you will have to start only one service and that service would be "OracleServiceORCL".

Right click on the service name OracleServiceORCL and just select Start/Stop depending on whether you want to start or stop your database.

'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

$ getconf PAGE_SIZE

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:


# sysctl -p

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