Checking SQL DB Availability
Hello everybody. I have a little question. Im creating a script for checking the status of different servers, and everything is running fine except for one thing. I have to check if certain DBs are connectables, I dont care anything else, nor running querys nor updating tables, the only thing I need to know is if the DB is connectable. It should be an easy task but frankly Im not very sure how to do it, so I tried the code below. And the problem I got with it is an "sqlplus : not found" from the unix shell. If anyone could help me itd be great. Thanks in advance.
Here goes what I have until now. If anyone knows another way thats great, I really dont care HOW to do it, just that it works.
#!/bin/bash
dbconnection=1
echo "Setting environment"
ssh -l myuser UNIXSERVER ". /apps/Ascential/DataStage/DSEngine/dsenv"
echo "Connecting to SQL"
dbcoonection=$(ssh -l myuser UNIXSERVER "sqlplus ????@????/????")
dbconnection=$?
echo "Status = $dbconnection"
if [ "$dbconnection" -lt "1" ]; then
echo "Connected"
else
echo "Not connected"
fi

script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
