Default Port and its Assignments (http,https,LDAP,Telnet,SSH,FTP etc)

Operating System reserves first 1024 ports for its internal usage and each port within 1024 port has been assigned for different protocols.  When I say reserved it means that only Root/Administrator user can change the preferences. Here are the list of ports and their default assignments.


PortUsage
21FTP
22SSH
23Telnet
80HTTP
66Oracle SQL
443HTTPS

513RAW/Rlogin
1521Database Listener

'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.
