=head1 db2setup
|
|
|
|
|
|
|
|
This script is called after the installation of DB2
|
|
on xCAT. It will automate the setup of the DB2 to run
|
|
xCAT on the IBM DB2 database on AIX and Linux.
|
|
On AIX ( AIX61J - AIX61 TL5(AIX 6.1.5.0)) or later and Linux.
|
|
As an option it will also setup the ODBC for C/C++ applications
|
|
to be able to use the database.
|
|
It will setup an xcatdb
|
|
database ,a db2instance id, name xcatdb ( same as database),
|
|
and instance password to be used in the /etc/xcat/cfgloc file
|
|
to access the database.
|
|
It will interact for the password to assign to the xcatdb
|
|
for the Unix id and DB2 instance id,
|
|
unless the XCATDB2PW env var is set to the password for the instance id.
|
|
For Client setup, it will interact for the hostname or ip address
|
|
of the DB2 Server as known by the Service Node, unless the
|
|
XCATDB2SERVER environement variable is set.
|
|
See man db2setup for more information and the xCAT2SetupDB2.pdf
|
|
documentation.
|
|
The script will assume the default install paths of /opt/IBM/db2 for AIX and
|
|
/opt/ibm/db2 for Linux, unless overridden with the XCATDB2INSPATH
|
|
environment variable.
