SQL log in from Cron job - sql

Question

On RHEL 7, I am trying to access a SQL table. When I run the code from terminal I can access the database and the script runs as expected. When I run the same script from crontab I get an error:
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
Here is my code:
getSequence()
{
SQLPLUS=/oracle/app/oracle/product/12c/bin/sqlplus
seq_num=$($SQLPLUS -S $OPS_DB_USER/$OPS_DB_ORACLE_PASSWD<<-EOF
set heading off
set feedback off
select Sequence.nextval from dual;
EOF)
VERSION=`printf "%07d" $seq_num`
}

Answer 1

If the script runs as expected. Make sure the permissions are set correctly on the script so when the cron runs it has the correct permissions to execute the script. Double check your environment variables as well. Here is an example of how I call a proc using a bash script. Hope this helps.
#!/bin/bash
sqlplus -s <<%%
$DBLOG/$DBPWD#$ORACLE_SID
exec "my_proc"();
exit
%%
