The current backup procedure we using a tar command in linux.
The files are stored in one partition in different folders. The docs stores in day wise folders like ex: /usr/data/xyz/20050129, /usr/data/xyz/20050130 .............etc

We run WebSphere and by default it wants to install everything under /usr. While I can understand the default (everyone has a /usr) I would like to move this over to a dedicated volume group called apps and then setup my lv's and fs's here. Our WebSphere Admin doesn't like this because apparently... (1 Reply)
Hi all,
I have worked on HP UNIX and now i have moved to SunSolaris which i never used to work.

Hi,
I have written a script which calls a process which ends up in a reboot of the system. At the end of the reboot it prompts for login & i need to provide the login details. am not able to figure out hw to do this.
Doubt: will echoing login details after calling the process work?
for ex:... (1 Reply)

sigspace
sigspace(2) System Calls Manual sigspace(2)NAME
sigspace - assure sufficient signal stack space
SYNOPSIS DESCRIPTION
requests additional stack space that is guaranteed to be available for processing signals received by the calling process.
If the value of stacksize is positive, it specifies the size of a space, in bytes, which the system guarantees to be available when pro-
cessing a signal. If the value of stacksize is zero, any guarantee of space is removed. If the value is negative, the guarantee is left
unchanged; this can be used to interrogate the current guaranteed value.
When a signal's action indicates that its handler should use the guaranteed space (specified with a or call (see bsdproc(3C)), the system
checks to see if the process is currently using that space. If the process is not currently using that space, the system arranges for that
space to be available for the duration of the signal handler's execution. If that space has already been made available (due to a previous
signal), no change is made. Normal stack discipline is resumed when the signal handler first using the guaranteed space is exited.
The guaranteed space is inherited by child processes resulting from a successful system call, but the guarantee of space is removed after
any system call (see fork(2) and exec(2)).
The guaranteed space cannot be increased in size automatically, as is done for the normal stack. If the stack overflows the guaranteed
space, the resulting behavior of the process is undefined.
Guaranteeing space for a stack can interfere with other memory allocation routines in an implementation-dependent manner.
During normal execution of the program, the system checks for possible overflow of the stack. Guaranteeing space might cause the space
available for normal execution to be reduced.
Leaving the context of a service routine abnormally, such as by (see setjmp(3C)), removes the guarantee that the ordinary execution of the
program will not extend into the guaranteed space. It might also cause the program to lose forever its ability to automatically increase
the stack size, causing the program to be limited to the guaranteed space.
RETURN VALUE
Upon successful completion, returns the size of the former guaranteed space. Otherwise, it returns -1 and sets to indicate the error.
ERRORS
fails and the guaranteed amount of space remains unchanged if the following occurs:
[ENOMEM] The requested space cannot be guaranteed, either because of hardware limitations or because some software-
imposed limit would be exceeded.
WARNINGS
The guaranteed space is allocated using malloc(3C). This use might interfere with other heap management mechanisms.
Methods for calculating the required size are not well developed.
Do not use in conjunction with the facilities described under sigset(3C).
Do not use in conjunction with sigstack(2).
In HP-UX release 11.11, use of in threads created with process contention scope could result in undefined behavior. This function will
continue to be reliable in threads created with system contention scope.
APPLICATION USAGE
Threads Considerations
Each thread may define an alternate signal handling stack.
LWP (Lightweight Processes) Considerations
Each LWP may define an alternate signal handling stack.
