Viewing Machine performance in unix and linux

1. display cpu quantity: hp-unix: ioscan-Cprocessor | grepprocessor | wc-lSolais: psrinfo-v | grep & quot; Statusofprocessor & quot; | wc-llinux: cat/proc/cpuinfo | grepprocessor... 1. display the number of CPUs:
Hp-unix: ioscan-C processor | grep processor | wc-l
Solais: psrinfo-v | grep "Status of processor" | wc-l
Linux: cat/proc/cpuinfo | grep processor | wc-l
AIX: lsdev-C | grep-I processor | wc-l
2. display the memory quantity (top ):
Solaris: prtconf | grep-I mem
AIX: root> lsdev-C | grep mem
Memo: Available 00-00 Memory
LINUX: free
HP-UNIX: swapinfo-tm
3. storage space:
Df-h
4. run the following command to view the kernel version:
Cat/proc/version
Uname-
5. view the linux version:
Lsb_release-
Cat/etc/issue
 
6. Database Status:
SGA: show sga
Archive: archive log list
Temporary tablespace:
Select * from database_properties d where d. PROPERTY_NAME = 'default _ TEMP_TABLESPACE ';
Select TABLESPACE_NAME, FILE_NAME, BYTES/1024/1024 "SIZE (MB)" from dba_temp_files;
Tablespace:
Select a. tablespace_name TABLESPACE_NAME,
A. all_space ALL_SPACE,
A. all_space-B. free_space USED_SPACE,
Substr (to_char (a. all_space-B. free_space)/a. all_space * 100 ),
1,
4) | '%' "% USED ",
B. free_space FREE_SPACE,
Substr (to_char (B. free_space/a. all_space * 100), 1, 4) | '%' "% FREE"
From (select sum (bytes/1024/1024) all_space, tablespace_name
From dba_data_files
Group by tablespace_name
Order by tablespace_name),
(Select sum (bytes/1024/1024) free_space, tablespace_name
