Answer 1

If you don't want to catalog the remote database, you may construct the configuration file on the fly to make it work with the Db2 command line processor.
The script constructs temporary configuration file and uses the corresponding environment variable with this file name saving its previous value and reverting it back after the db2 connect command.
Linux & Unix example
#!/bin/sh
if [ $# -eq 0 ]; then
echo "Usage: . ./db2connect host:port/dbname USER username [USING password]" >&2
exit 1
fi
DSN=${1}
CFGFILE=./db2dsdriver.cfg.$$
dbname=${DSN#*/}
hp=${DSN%/*}
host=${hp%:*}
port=${hp#*:}
cat > ${CFGFILE} <<EOF
<configuration>
<dsncollection>
<dsn alias="${dbname}" name="${dbname}" host="${host}" port="${port}"/>
</dsncollection>
<databases>
<database name="${dbname}" host="${host}" port="${port}"/>
</databases>
</configuration>
EOF
cfg_bkp=${DB2DSDRIVER_CFG_PATH}
export DB2DSDRIVER_CFG_PATH=${CFGFILE}
shift
db2 connect to ${dbname} "$#"
export DB2DSDRIVER_CFG_PATH=${cfg_bkp}
rm -f ${CFGFILE}
Usage:
. ./db2connect 192.168.131.16:25000/SAMPLE USER db2admin USING Password#123
Don't remove space between the 1-st dot and the path to this executable file.
Windows example:
#echo off
if [%1] == [] (
echo Usage: %~nx0 host:port/dbname USER username [USING password]
goto :eof
)
set cfg_bkp=%DB2DSDRIVER_CFG_PATH%
set CFGFILE=.\db2dsdriver.cfg.tmp
set DB2DSDRIVER_CFG_PATH=%CFGFILE%
for /F "tokens=1-3 delims=:/" %%i in ('echo %1') do (
set host=%%i
set port=%%j
set dbname=%%k
)
if exist %CFGFILE% del %CFGFILE%
db2cli writecfg add -database %dbname% -host %host% -port %port% > nul
db2cli writecfg add -dsn %dbname% -database %dbname% -host %host% -port %port% > nul
db2 terminate
db2 connect to %dbname% %2 %3 %4 %5
set DB2DSDRIVER_CFG_PATH=%cfg_bkp%
del %CFGFILE%
Usage:
db2connect.bat 192.168.131.16:25000/SAMPLE USER db2admin USING 'Password#123'
