ASE-15 isql command can not find sybase home on CentOS 7

Question

I installed ASE-15 under directory /opt/sybase on CentOS 7 VM, then I ran SYBASE.sh to set environment variables, but it didn't work, because it outputs nothing when I typing echo $SYBASE on OS. So I set environment variables manually by typing cat SYBASE.env >> ~/.bash_profile, the content in SYBASE.env below.

[sybase@localhost sybase]$ cat /opt/sybase/SYBASE.env
SYBASE_JRE7_32=/opt/sybase/shared/JRE-7_0_7_32BIT
SYBASE_JRE7=/opt/sybase/shared/JRE-7_0_7_64BIT
SYBASE_JRE7_64=/opt/sybase/shared/JRE-7_0_7_64BIT
SYBASE_OCS=OCS-15_0

[sybase@localhost sybase]$ 

However, it occurs an error below when I execute isql cmd to connect with ASE-15 Database.

[sybase@localhost sybase]$ isql


The context allocation routine failed when it tried to load localization files!!
One or more following problems may caused the failure

Your sybase home directory is /home/sybase. Check the environment variable SYBASE if it is not the one you want!
Cannot access file /home/sybase/config/objectid.dat
An error occurred when attempting to allocate localization-related structures.
[sybase@localhost sybase]$ 

Then I input echo $SYBASE to check if the environment variable $SYBASE is correct.

[sybase@localhost sybase]$ echo $SYBASE
/opt/sybase

So I think I have specified the sybase home directory /opt/sybase, why isql command find file objectid.dat under /home/sybase/config instead of /opt/sybase/config?

Answer 1

Sybase's suffix and permissions for the SYBASE.[csh|sh] files are a bit misleading. You don't want to execute/run these files but rather source them, eg:

# sh / bash / ksh
. SYBASE.sh

# csh
source SYBASE.csh

You should only have to add the following to your profile to successfully access isql:

# sh / bash / ksh
SYBASE=/opt/sybase
. ${SYBASE}/SYBASE.sh
