Sybase ADAPTIVE 15.0.2 - Manual (Page 42)

Installing server components
26 Adaptive Server Enterprise
To adjust shared memory segments of the operating system, add the
following line to the configuration file /etc/system:
set shmsys:shminfo_shmseg=x
where x is the number of shared memory segments.
19
20
If after adjusting the SHMMAX parameter the server fails to reboot you may
also need to increase the value of another Kernel parameter, SHMALL, which
is the maximum amount of shared memory that can be allocated. Its value is in
the file /proc/sys/kernel/shmall. This task requires root permission.
Installing server components
Follow the instructions in this section to install Adaptive Server, Backup
Server, and Monitor Server.
Note Adaptive Server Enterprise 15.0.2 includes new major versions of
Adaptive Server and many of the supporting components. Installing Adaptive
Server version 15.0.2 into the same directory with existing products should not
impact the existing products. However, installing other products on top of
Adaptive Server version 15.0.2 will likely result in one or more products not
working correctly.
Sybase strongly recommends that Adaptive Server version 15.0.2 be installed
into its own directory if possible. Where this is not practical and other products
must be installed into the same directory, Adaptive Server version 15.0.2
should be installed last.
