I recently installed DB2 v8.1 on Linux. The installation went
smoothly. I can now connect to the "sample" database and work with
it.
However, I noticed the following. How do I go about fixing these?
1) When in db2, if the SQL statements contain a syntax error, the
whole application crashes. This happens, for example, if I type
"select * from emps" where the table emps does not exist.
That should not happen:
db2 => select * from emps;
SQL0204N "JDBEYER.EMPS" is an undefined name. SQLSTATE=42704
db2 =>
2) db2cc does not start, gives error messages about "Can't find
library
db2jdbc (libdb2jdbc.so)"
I do not use db2cc; got in the habit of not using that in V6.1 days when
it ran so slowly that I could not stand it.
Did you install it?
trillian:jdbeyer[~]$ locate libdb2jdbc.so
/opt/IBM/db2/V8.1/lib/libdb2jdbc.so
/opt/IBM/db2/V8.1/lib/libdb2jdbc.so.1
3) db2ca does not start. It too gives error messages about some java
class: "Can't find library db2adtca (libdb2adtca.so) in
java.library.path"
trillian:jdbeyer[~]$ locate libdb2adtca.so
/opt/IBM/db2/V8.1/lib/libdb2adtca.so
/opt/IBM/db2/V8.1/lib/libdb2adtca.so.1 4) How do I stop/start instances?
db2istrt
In Red Hat Enterprise Linux 3 ES, I have a file in /etc/rc.d/init.d for
that. Named IBMdb2. It is like this:
#!/bin/sh
# chkconfig: 35 98 02
# description: Start and Stop IBM's db2 dbms.
BASE=/opt/IBM/db2
VERSION=V8.1
INSTANCE=/dataA/db2inst1 # Where (a small part of the) instance will be.
# Set the path.
PATH=/sbin:/bin:/usr/bin:/usr/sbin
.. /etc/rc.d/init.d/functions
# Check we have the start and stop programs.
test -x $INSTANCE/sqllib/adm/db2start || exit 0
test -x $INSTANCE/sqllib/adm/db2stop || exit 0
test -x $BASE/$VERSION/bin/db2 || exit 0
case "$1" in
start)
# Check if IBMdb2 not already running
if [ ! -f /var/lock/subsys/IBMdb2 ]; then
echo -n 'Starting IBMdb2 daemons: '
