Caché Installation Guide - InterSystems Documentation

‡ The 1024 KB number is approximate. It is based on the current size of the Caché executable and
grows with the partition size you allocate to each Caché process. On most systems, provide only as
much swap space as necessary. However, some systems require you to provide swap space for the
worst case. Under these conditions, you need to increase this number to as high as 1.5MB, depending
on the partition size you specify.
Be sure to confirm that your UNIX system permits the amount of swap space you require. For specific
information about swap space on your system, consult your UNIX operating system manual.
B.1.2.1 Solaris Swap Space
To calculate swap space for the Solaris platform:
swap –l
Example:
>swap –l
swapfile dev swaplo blocks free
/dev/dsk/c0t2d0s0 136,0 16 526304 526304
/dev/dsk/c0t2d0s1 136,1 16 2101184 2101184
B.1.2.2 Tru64 UNIX Swap Space
To display swap space for Tru64 UNIX:
/usr/sbin/swapon -s
Information for each swap partition is displayed similar to the following example:
Swap partition /dev/disk/dsk1b (default swap):
Allocated space: 16384 pages (128 MB)
In-use space: 10452 pages ( 63%)
Free space: 5932 pages ( 36%)
Swap partition /dev/disk/dsk4c:
Allocated space: 128178 pages (1001 MB)
In-use space: 10242 pages ( 7%)
Free space: 117936 pages ( 92%)
Total swap allocation:
Allocated space: 144562 pages (1.10GB)
Reserved space: 34253 pages ( 23%)
In-use space: 20694 pages ( 14%)
Available space: 110309 pages ( 76%)
