Verify that your network software is configured.
Sybase software uses network software even if Adaptive Server and Sybase client
applications are installed on a machine that is not connected to a network.
If you are having connection problems, or to verify your network configuration, ping the
host.
10.
Adjust the shared memory for your operating system.

Adjusting the Operating System Shared Memory Parameters
Adjust shared memory segments if Adaptive Server cannot obtain large memory as a single
segment, or if Backup Server stripes fail due to insufficient segments.
Depending on the number and types of devices used for backup (dump) and recovery (load),
you may need to adjust the shared memory segment parameter in the operating system
configuration file to accommodate concurrent Backup Server processes. There are six default
shared memory segments available for process attachments.
If any reconfiguration through sp_configure requires additional memory, Adaptive Server
allocates shared memory segments after start-up. To account for these additional segments,
allocate the maximum memory available to Adaptive Server by using the allocate max shared
memory configuration parameter. See the System Administration Guide .
1.
The operating system shared memory default, for most Linux releases is 32MB. The
minimum required by Adaptive Server is 64MB for default Server with 2K pages. A higher
value is required if you plan to increase Adaptive Server’s total memory. Set the stack size
to unlimited to avoid shared memory attachment problems. Set this using ulimit -s
unlimitedon Bourne Shell, or limit stacksize unlimited on C-Shell.
2.
Use the sysctl(8) method to check and adjust the operating system shared memory
parameter:
To check the current shared memory size, enter:
# /sbin/sysctl kernel.shmmax
To adjust the shared memory size at runtime, enter the following, where nnn is
1073741824 for 1GB of shared memory:
