System uptime

[Ian Miller.]

"SHOW SYSTEM/CLUSTER/NOPROC"
- I had not noticed that one before - I really do learn things here every day :-)

Note that this command shows the up time of each system in the cluster. (only 200 days for the system I looked at :-)
The cluster uptime can be longer and is given by the commands given in an earlier reply.

Thanks to you you all for your responses. For all those interested "My cluster has an uptime of: 177 21:40:12.26"

Andre,

You can get this also in any VMS language, by calling apropriate system services. There is a C example:

#include
#include
#include

#include

int main ()
{
__int64 ftime;
__int64 now;
struct
{
unsigned short len;
unsigned short code;
__int64 * buff;
void * rlen;
unsigned long end;
} itmlst = {8,SYI$_CLUSTER_FTIME,&ftime,0,0};
unsigned short timlen;
char asctim[21];
struct dsc$descriptor timbuf = {20,DSC$K_DTYPE_T,DSC$K_CLASS_S,asctim};
int stat;
stat = sys$getsyiw (0,0,0,&itmlst,0,0,0);
if (!(stat & 1)) return stat;
stat = sys$gettim (&now);
if (!(stat & 1)) return stat;
ftime -= now;
stat = sys$asctim (&timlen , &timbuf , &ftime , 0);
if (!(stat & 1)) return stat;
asctim[timlen] = 0;
printf ("Cluster uptime is %s\n" , asctim);
return 1;
}

minor point - iosb should always be included and checked in system calls when they can be. In the case of this getsyiw it probably does not matter as its just reading a system data cell but you never know.

Now I expect examples in perl, python, and other favorite programming languages :-)
