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.

USER_CLUSTERS(5)					 Debian PostgreSQL infrastructure					  USER_CLUSTERS(5)

NAME

       user_clusters - File linking users to PostgreSQL clusters

DESCRIPTION

       This  file  maps users against the database clusters to which they will connect by default. However, every user can override these settings
       in ~/.postgresqlrc.

       When scanning this file, the first matching line will be used.  It is a good idea to provide a default explicitly, with a final line  where
       both user and group are set to *.

       If  there  is  no default, the implicit default is to connect to the cluster whose postmaster is listening on port 5432 and to the database
       matching the user's login name.

FORMAT

       Comments are introduced by the character #.  Comments may follow data on a line; the first comment character terminates the  data.  Leading
       whitespace and blank lines are ignored.

       Each uncommented, non-blank line must describe a user, group or the default (where both user and group are set to *).

       Fields must be given in the following order, separated by white space:

       USER   The login id of the Unix user to whom this line applies. The wildcard character * means any user.

       GROUP  The group name of the Unix group to which this line applies. The wildcard character * means any group.

       VERSION
	      The major PostgreSQL version of the cluster to connect to.

       CLUSTER
	      The name of a cluster to connect to. A remote cluster is specified with host:port. If port is empty, it defaults to 5432.

       DATABASE
	      Within  the  cluster,  the database to which the user will connect by default if he does not specify a database on the command line.
	      If this is *, the default database will be the one named by the user's login id.

NOTES

       Since the first matching line is used, the default line must come last.
