CPU -- Critical Patch Updates

CPU -- Critical Patch Updates

This is a way through with Oracle releases security fixes for Oracle products. CPU's are release for the supported products mainly for the following reasons.


1) Data confidentiality, i.e. an attacker is able to view information that he or she should be prevented from viewing.
2) Data integrity, i.e. an attacker is able to modify information that he or she should be prevented from modifying.
3) System availability, i.e. an attacker is able to disrupt legitimate use of or access to a system.

CPU's patches are released every 3 months on a specific date. So if you are planning to apply any of the security patches/fixes then you can wait for the recent one. The dates are as follows,

a. 15th Jan
b. 15th Apr
c. 15th Jul
d. 15th Oct

Per Oracle patches will be released on tuesdays close to 15th of the months mentioned above.

'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.
