If condition fails, advise using wildcard

OS Environment: HP-UX B.11.31 U ia64

I am using the shell script code to connect to Oracle RAC database.
Passing the parameter of cluster database name.


Code:
typeset -l DB_ID=$1
+ typeset -l DB_ID=sivDB

#---- 3. SetDB validation -------------
if [ "$ORACLE_SID"x != "${DB_ID}"x ]; then
 print "============================"
 print " setdb failed for $db"
 print "============================"
 exit
fi

+ [ sivDB1x != sivDBx ]
+ print ========================================================
+ print  setdb failed for
 setdb failed for
+ print ========================================================
+ exit

Question:
Here I want the IF condition to succeed if first 5 characters of $ORACLE_SID matches with ${DB_ID}. Please advise.

For example: [ sivDB1x != sivDBx ]

Note: Actually I pass the Oracle RAC DB name. During the setdb ( setting the Oracle Environment ) it sets the instance running on the node like sivDB1 for Node1 and sivDB2 for Node 2 for the RAC DB of sivDB.

There is no character "x" in balajesuri's post.
What command did you issue?
