    Can someone please Help Me.I just setup oracle 9i on Linux 7.2.
    When i am in sqlplus and run startup nomount, i recieve the following error

    ORA-03113: end-of-file on communication channel

    I don't know if it is my listener? Can one use 8i client on 9i Database? (STUPID QUESTION, but i would just like to confirm)

    ora 3313


    How many semaphores do you have? and what is the processes parameter in the init.ora.

    Somehow somewere there is a typo in your init.ora file.

    I have seen this once when setting processes to high.

    Try 64 for his parameter.

    ORA-3113 is a generic error message that oracle sends out. The cause of the problems could be at various levels. The troubleshoot differed from level to level. Do a search on this site under search forums and you will sure find a trubleshooting list on one of the posts.

    I tried searching on the site but most of the solutions doesn't work, or members recieve the same error message when trying to do something else

    Can you precisely tells what happens.

    When you do > startup nomount
    what happens?
    If this give the ora3313 the problem sits in the init.ora file.

    If this works you can try >alter database mount;

    and look if it mounts.

    Hope to hear from you.

    When you connect to Oracle, a new server process is created on the server. The client (svrmgrl) communicates with the server process. When you get an ORA-3113 it means that the server process crashed hard.

    When this happens, check the alert log file in the bdump directory. There will probably also be a process log file in the udump directory. These will describe why the error happened.

    A1) Errors connecting as SYSDBA / Internal OR on startup nomount
    	There is something fundamental wrong with the software / environment
    	if you cannot connect to Server Manager as a DBA user. 
    	The steps here cover errors such as ORA-3113, ORA-12547: TNS:lost contact
    	or similar errors connecting to Oracle or starting the instance NOMOUNT.  
    	Check the following items:
    	A1.1)	If possible reboot the server disabling any automatic
    		startup of Oracle before you do so. This may seem drastic
    		but helps make sure you are working from a consistent 
    		starting point.
    	A1.2) 	Check your environment points at the expected ORACLE_HOME
    		and ORACLE_SID and that TWO_TASK is not set (Unix) or
    		LOCAL is not set (NT registry).
                    Check the USER_DUMP_DEST and BACKGROUND_DUMP_DEST and default
                    trace directories under this environment for any user trace 
                    files or alert log entries generated. These may help indicate
                    the cause of the problem. 
                    Eg: ORA-600[SKGMINVALID] may indicate a problem with the
                        shared memory Unix parameters on Unix systems.
                    Try to show that any trace file / alert log entry you 
                    find is truely related to the "CONNECT" command by re-issuing
                    the "connect" and checking for a new trace file / alert entry
                    at the time of the error.
            A1.3)   Unix only:
    		Some Unix platforms need LD_LIBRARY_PATH to be set 
                    correctly to resolve any dynamically linked libraries.
                    As the user with the problem:
                            % script /tmp/ldd.out
                            % id
                            % cd $ORACLE_HOME/bin
                            % ldd oracle
                            % exit
                    If the 'ldd' command does not exist go to the next step below.
                    Check that all lines listed show a full library file. If there
                    are any 'not found' lines reported contact Oracle support
                    with the output of /tmp/ldd.out .
            A1.4)   Unix only:
    		Your 'oracle' executable may be corrupt. Relink it thus:
                            Log in as the 'oracle' user.
                            % script /tmp/relink.out
                            % cd $ORACLE_HOME/rdbms/lib
    			% mv $ORACLE_HOME/bin/oracle $ORACLE_HOME/bin/oracle.dd.mon.yy
                            % rm -f ./oracle        
                            % make -f ins_rdbms.mk ioracle
                            % exit
    		Prior to Oracle7.3 the relink command was:
    			make -f oracle.mk ioracle
                    If this reports any errors Oracle support will need to see
                    the contents of the file /tmp/relink.out .
    	A1.5)   Have you installed the Parallel Server Option ?
                    ORA-3113 can occur if you have installed the Parallel 
    		Server Option but do NOT have a Distributed Lock Manager 
    		installed or running correctly. 
    		  If the Parallel Server Option was installed by accident
    		  then it can be de-installed by relinking.
                            Shut down any Oracle instances
                            % script /tmp/relink.out
                            % cd $ORACLE_HOME/rdbms/lib
                            # 'oracle' should not exist so delete it if it present
                            % rm -f oracle
                            % make -f ins_rdbms.mk no_parropt ioracle
                            % exit
    		  NB: Do NOT deinstall the Parallel Server Option if the
    		      database is using Parallel Server unless both nodes
    		      are shut down otherwise database corruption could occur.
    	A1.6)   If the error is on STARTUP NOMOUNT:
    			Check the init.ora file used to start the database.
    			This provides the configuration details used
    			configure the instance. To help isolate the problem
    			it may be useful use a very basic init.ora file
    			when starting the instance. If this works then 
    			parameters can be increased / introduced one at a 
    			time to see if there is a problem with a particular
    	A1.7) 	Check for server side trace files which may give more 
    		indication what the underlying problem is.
    		See section C for details on how to check
    		for server trace files.
    	A1.8) 	Ensure there is free disk space in:
    		  a. Your USER_DUMP_DEST and BACKGROUND_DUMP_DEST locations
    		  b. Your AUDIT destination (Unix)
    			The default is $ORACLE_HOME/rdbms/audit
    		  c. Your Oracle Trace directory if Oracle Trace is enabled
    A2) Errors Mounting the database
    	Check all the items in A1 first.
    	If an error occurs when mounting the database there may be problems
    	with the control-files or data files, or with resources required to
    	open these files.
    	A2.1) 	The location of the control files are specified in the 
    		init.ora file.  Try mounting using each controlfile in 
    		eg: "Shutdown abort", 
    		    edit the init.ora to refer to ONE of the controlfiles only, 
    		    "startup nomount", 
    		    "alter database mount"
    		Repeat for each controlfile to see if any controlfile works.
    	A2.2)	It is possible to re-create the controlfiles if you know the 
    		location of all datafiles and online logs, or to restore an old
    		backup controlfile. Always back up the current controlfiles before
    		restoring any backup copies or issuing a CREATE CONTROLFILE
    		The steps for this are not documented here.
            A2.3)   Unix: 
                    Some unix platforms have a 'truss' command (or 'tusc').
    		If available this can be used to help trace how far Oracle 
    		gets before the error occurs.
                            % truss -o /tmp/truss.out -f svrmgrl
                    Keep the file /tmp/truss.out safe - Oracle Support MAY need to see it.
