Virtual / Physical Memory Usage

Solaris is a virtual memory system. The total amount of memory that you can use is

increased by adding swap space to the system. If you ever see "out of memory"

messages, adding swap space is the usual fix. Performance of the system is very

dependent on how much physical memory (RAM) you have. If you don't have enough

RAM to run your workload, performance degrades rapidly.

Physical memory usage can be classified into four groups:

Kernel memory mapped into kernel address space

Process memory is mapped into a process address space

Filesystem cache memory that is not mapped into any address space

Free memory that is not mapped into any address space

RMCmem includes a simple command to summarize this:

# /opt/RMCmem/bin/prtmem

Total memory: 989 Megabytes

Kernel Memory: 60 MegabytesApplication: 110 Megabytes

Executable & libs: 42 Megabytes

File Cache: 757 Megabytes

Free, file cache: 11 Megabytes

Free, free: 6 Megabytes

Determine the memory used by each Oracle background process on a Solaris

============================================================

# ps -u oracle -f

UID PID PPID C STIME TTY TIME CMD

oracle 359 1 0 12:26:17 ? 0:00 ora_pmon_DIA3

3/3

oracle 361 1 0 12:26:17 ? 0:01 ora_dbw0_DIA3

oracle 363 1 0 12:26:17 ? 0:01 ora_lgwr_DIA3

oracle 365 1 0 12:26:17 ? 0:18 ora_ckpt_DIA3

oracle 367 1 0 12:26:17 ? 0:01 ora_smon_DIA3

oracle 369 1 0 12:26:17 ? 0:00 ora_reco_DIA3

oracle 371 1 0 12:26:17 ? 0:00 ora_snp0_DIA3

oracle 373 1 0 12:26:17 ? 41:50 ora_s000_DIA3

oracle 375 1 0 12:26:17 ? 0:00 ora_d000_DIA3

oracle 377 1 0 12:26:18 ? 0:00 ora_d001_DIA3

Second, you then enter the following commands for the DB Writer process

(ora_dbw0_DIA3) with process id = 361 as an example.

# /usr/proc/bin/pmap 361 | grep "shmid"

80000000 82992K read/write/exec/shared [ shmid=0x2 ]

# /usr/proc/bin/pmap 361 | grep "total"

total 124232K
