-
-!!1.4 Aim of the HOWTO
-
-
-
-In this HOWTO I will attempt to cover installation and basic admin of an Oracle database running on a Linux machine. In particular I will cover Oracle server installation, SQL*Net configuration and client configuration.
-
-
-
-
-
-This document is not an in depth tutorial on using or administering an Oracle database, if that is what you are looking for there are great books on those subjects published by O'Reilly and others.
-
-
-
-
-
-I am also not going to cover the development of Oracle programs under UNIX. If this is absolutley necessary to you then I would recommend that you purchase the SCO development system (with !OpenServer 5.x) from SCO, which I am told can be obtained for a very reasonable US $19, from www.sco.com.
-
-!!1.5 Requirements
-
-
-
-I am assuming a number of items that you will need for following the HOWTO.
-
-
-*__Oracle Server CD for SCO Openserver (Version 7.3.3...)__
-
-
-
-This __must__ be a legal copy. Remember that Oracle are a profit making company and charge for their products. If you want a free SQL compliant database use PostgresSQL or similar.
-
-
-It is also possible to install oracle, using a 60 day evaluation licence, from a downloadable tar file from the Oracle web site. I have not personally tried this and it is completely unverified.
-
-
-
-
-
-*
-
-*__A Linux Server__
-
-
-
-You wouldn't be reading this without one...would you?
-
-
-
-
-
-*
-
-*__Kernel 2..30+__
-
-
-
-I cannot guarantee that these instructions will be accurate for any other Kernel. (Not that I am guaranteeing it for 2..30 either...).
-
-
-
-
-
-*
-
-*__iBCS__
-
-
-
-It is very important to have this installed and working with the latest possible version for your platform. (I am using iBCS-2.-10.i386.rpm from Redhat Linux).
-
-
-
-
-
-*
-
-*__Lots of disc space__
-
-
-
-600 Mb+ is a reasonable amount. It is possible to install with less but you need to make some sacrifices, and I never like starting with those. However, I will attempt to point out areas in which space can be freed up.
-
-
-
-
-
-*
-
-*__32Mb+ Ram__
-
-
-
-I know that this sounds like a lot, especially in Linux terms, but remember that Oracle is a complex piece of software. You wouldn't have the same reservations on SCO!
-
-
-
-
-
-I am not saying that Oracle doesn't work with less, just that it is less than Oracle recommend and I wouldn't suggest it.
-
-
-
-
-
-*
-
-*__Licenses from Oracle__
-
-
-
-I know that I have already mentioned this but I want to be clear that this is important. Using software from Oracle without a license is illegal.
-
-
-
-
-
-*
-
-
-
-
-
-!!1.6 News From Oracle Corporation
-
-
-
-Oracle have bowed into pressure from the Linux community. Oracle Corporation have decided to __officially__ support Oracle 8 on the Linux (i386) platform. This should be released in December 1998, according to the Oracle website.
-
-
-
-
-
-Better still Oracle will also be porting Oracle Applications to the linux platform. This should be available in the first half of 1999, according to the Oracle website.

-
-!!2. Installing the Oracle Software
-
-!!2.1 Server Preparation
-
-
-!Creating an Oracle User
-
-
-Unsurprisingly we require a user to hold the Oracle database. Since we have no desire to relink the Oracle kernel (more about that later) we have to accept the Oracle defaults for user name and group name. This includes the user ORACLE and the group DBA.
-
-
-
-
-
-#Login as Root
-
-
-
-
-#
-
-#Create the oracle user and the group dba.
-
-----
-
-$ groupadd dba
-$ useradd oracle
-
-----
-
-
-#
-
-# Ensure a home directory is created for the user oracle.
-
-----
-
-$ mkdir /home/oracle
-$ mkdir /home/oracle/7.3.3..0 (Version of Oracle)
-$ chown -R oracle.dba /home/oracle
-
-----
-
-
-#
-
-
-
-
-
-!!2.2 Installing from CDROM
-
-
-
-Unfortunately the Oracle Installer on the SCO disc will not work. A variety of problems can be experienced, from core dumps to hangs. As a result we need to copy the files from the CDROM manually and uncompress them:
-
-
-(Ensure the CDROM is mounted on the system).
-
-
-#Log on as Oracle
-#
-
-#Change directory to /home/oracle/7.3.3...
-#
-
-#Copy all install files from CDROM
-
-----
-
-$ cp -a /mnt/cdrom/* .
-
-----
-
-
-#
-
-#Un-compress all Oracle files on CDROM.
-
-----
-
-$ find . -name *_ -exec ~/7.3.3../orainst/oiuncomp {} \;
-
-----
-
-
-#
-
-
-
-
-
-!!2.3 Post Installation Tasks
-
-
-!Tasks for Root
-
-
-Add the following lines to /etc/profile or add to the .profile for each user who is going to use Oracle.
-
-----
-
-# Oracle Specific
-ORACLE_HOME=/home/oracle/7.3.3..
-ORACLE_SID=orcl
-ORACLE_TERM=vt100
-export ORACLE_HOME ORACLE_SID ORACLE_TERM
-# Alter path for Oracle
-PATH="$PATH:$ORACLE_HOME/bin"
-
-----
-
-
-
-
-
-
-We also need to change the owner and permissions of the Oracle ulimit increase utility.
-
-----
-
-$ chown root.root $ORACLE_HOME/bin/osh
-$ chmod u+s $ORACLE_HOME/bin/osh
-
-----
-
-
-
-
-
-!Tasks for Oracle
-
-
-Change permissions for the Oracle files to ensure correct operation.
-
-----
-
-$ chmod +x $ORACLE_HOME/bin/*
-$ chmod u+s $ORACLE_HOME/bin/oracle
-
-----
-
-
-
-
-
-
-Oracle tools require the messages to be in the $ORACLE_HOME/tool_name/mesg directory.
-So, move the msb files from the msg_ship directories to the mesg directories.
-
-----
-
-$ mv $ORACLE_HOME/plsql/mesg/mesg_ship/* $ORACLE_HOME/plsql/mesg/.
-$ mv $ORACLE_HOME/rdbms/mesg/mesg_ship/* $ORACLE_HOME/rdbms/mesg/.
-$ mv $ORACLE_HOME/svrmgr/mesg/mesg_ship/* $ORACLE_HOME/svrmgr/mesg/.
-
-----
-
-Create the following directories if they do not exist:
-
-----
-
-$ mkdir $ORACLE_HOME/rdbms/log
-$ mkdir $ORACLE_HOME/rdbms/audit
-$ mkdir $ORACLE_HOME/network/log
-
-----
-
-
-!Things you can remove
-
-
-The following directories can safely be removed:
-
-
-*$ORACLE_HOME/guicommon2/
-*
-
-*$ORACLE_HOME/ctx/
-*
-
-*$ORACLE_HOME/md/
-*
-
-*$ORACLE_HOME/mlx/
-*
-
-*$ORACLE_HOME/precomp/
-*
-
-*$ORACLE_HOME/slax/
-*
-
-----
-
-!!3. Creating a Database
-
-
-Now the Oracle server is installed we need to create a database to test the installation.
-
-
-If you are using Oracle 7.2.x or earlier, please read the troubleshooting section below.
-
-!!3.1 Create the Initialisation File
-
-
-
-Copy the $ORACLE_HOME/dbs/init.ora to $ORACLE_HOME/dbs/initorcl.ora:
-
-----
-
-$ cd $ORACLE_HOME/dbs
-$ cp init.ora initorcl.ora
-
-----
-
-Modify it by adding the following lines:
-
-----
-
-db_name = orcl
-COMPATIBLE=7.3.3..
-
-----
-
-
-
-
-
-
-
-
-!!3.2 Creating the Database Install Script
-
-
-
-Create a script file called makedb.sql in the $ORACLE_HOME/dbs directory:
-
-----
-
-connect internal
-startup nomount
-set echo on
-spool makedb.log
-create database orcl
-maxinstances 1
-maxlogfiles 8
-datafile '$ORACLE_HOME/dbs/orcl_syst_01.dbf' size 40M reuse
-logfile
-'$ORACLE_HOME/dbs/orcl_redo_01.dbf' size 1M reuse,
-'$ORACLE_HOME/dbs/orcl_redo_02.dbf' size 1M reuse,
-'$ORACLE_HOME/dbs/orcl_redo_03.dbf' size 1M reuse;
-@$ORACLE_HOME/rdbms/admin/catalog.sql
-create tablespace rollback
-datafile '$ORACLE_HOME/dbs/orcl_roll_01.dbf' size 8.5M reuse;
-create tablespace temp
-datafile '$ORACLE_HOME/dbs/orcl_temp_01.dbf' size 5M reuse
-temporary;
-create tablespace users
-datafile '$ORACLE_HOME/dbs/orcl_user_01.dbf' size 10M reuse;
-create rollback segment r1 tablespace rollback
-storage ( optimal 5M );
-alter rollback segment r1 online;
-connect system/manager
-@$ORACLE_HOME/rdbms/admin/catdbsyn.sql
-connect internal
-@$ORACLE_HOME/rdbms/admin/catproc.sql
-connect system/manager
-@$ORACLE_HOME/sqlplus/admin/pupbld.sql
-spool off
-exit
-
-----
-
-
-
-
-
-!!3.3 Running the Database Installation Script
-
-
-
-Start svrmgrl and run the script:
-
-----
-
-$ cd $ORACLE_HOME/dbs
-$ svrmgrl
-Oracle Server Manager Release 2.3.3..0 - Production

-Redo Buffers 8192 bytes
-SVRMGR> @makedb
-<loads of messages>
-SVRMGR> exit
-Server Manager complete.
-
-----
-
-
-!!3.4 Starting the Database
-
-
-
-Firstly, we need to bring up the database by hand (we will automate this later on). To startup an Oracle database we need to issue the startup command when connected internally:
-
-----
-
-$ svrmgrl
-Oracle Server Manager Release 2.3.3..0 - Production
-Copyright (c) Oracle Corporation 1994, 1995. All rights reserved.
-Oracle7 Server Release 7.3.3..0 - Production Release

-Fixed Size 41876 bytes
-Variable Size 4140368 bytes
-Database Buffers 122880 bytes
-Redo Buffers 8192 bytes
-Database mounted.
-Database opened.
-SVRMGR> exit
-Server Manager complete.
-
-----
-
-
-!!3.5 Stopping the Database
-
-
-
-It is worth mentioning here that restarting a Linux server without shutting down the Oracle database first there is a high risk of corrupting the database.
-
-
-So, before we issue the Linux shutdown command it is wise to bring down the database:
-
-----
-
-$ svrmgrl
-Oracle Server Manager Release 2.3.3..0 - Production
-Copyright (c) Oracle Corporation 1994, 1995. All rights reserved.
-Oracle7 Server Release 7.3.3..0 - Production Release
-PL/SQL Release 2.3.3..0 - Production
-SVRMGR> connect internal
-Connected.
-SVRMGR> shutdown
-Database closed.
-Database dismounted.
-ORACLE instance shut down.
-SVRMGR> exit
-Server Manager complete.
-
-----
-
-
-!!3.6 Create a Default User
-
-
-
-The database, as created, has a two special users which are automatically created. These are:
-
-----
-
-Username Password
-SYSTEM MANAGER
-SYS change_on_install
-
-----
-
-
-
-
-
-
-These users are typically used to hold the standard data dictionary information for the database. It is a good idea to change the passwords from the defaults as soon as possible.
-
-
-This can be achieved by:
-
-----
-
-sqlplus system/manager
-SQL*Plus: Release 3.3.3..0 - Production on Sat Feb 21 12:43:33 1998
-Copyright (c) Oracle Corporation 1979, 1996. All rights reserved.
-Connected to:
-Oracle7 Server Release 7.3.3..0 - Production Release
-SQL> alter user system identified by <newpassword>;
-User altered.
-SQL> alter user sys identified by <newpassword>;
-User altered.
-SQL> exit;
-Disconnected from Oracle7 Server Release 7.3.3..0 - Production Release
-PL/SQL Release 2.3.3..0 - Production
-
-----
-
-
-
-
-
-
-Since the user system/manager is similar to using root on a UNIX machine, we need to create a user with less ability to cause damage. (remember to bring up the database before attempting to create a user)
-
-
-Connect to SQL*Plus and create a user:
-
-----
-
-$ sqlplus system/manager
-SQL*Plus: Release 3.3.3..0 - Production on Sat Feb 21 12:43:33 1998
-Copyright (c) Oracle Corporation 1979, 1996. All rights reserved.

-Oracle7 Server Release 7.3.3..0 - Production Release
-PL/SQL Release 2.3.3..0 - Production
-SQL> create user <user> identified by <psw>
-2 default tablespace users
-3 temporary tablespace temp;
-User created.
-SQL> grant connect, resource to <user>
-Grant succeeded.
-SQL> exit
-Disconnected from Oracle7 Server Release 7.3.3..0 - Production Release
-PL/SQL Release 2.3.3..0 - Production
-
-----
-
-
-
-Now that you have a new user on the system you can play with the new system. To login to the Oracle database:
-
-----
-
-$ sqlplus <user>/<password>
-
-----
-
-
-
-If this completes with no error messages then you have a working Oracle database. If you never want to connect to this database from anywhere but this server then the job is complete, enjoy!
-
-
-If, however, like most people you want to configure the networking software so that you can connect from other machines, keep on reading.
-----
-
-!!4. Configuring SQL*Net on the Server
-
-
-All of these files configure the Oracle networking software (SQL*Net, aka Net8 for Oracle8). These files should all be created on the server in the $ORACLE_HOME/network/admin directory.
-
-!!4.1 tnsnames.ora
-
-
-
-The TNSNAMES.ORA file identifies services available from the machine. On our instance here we will describe all databases that the server has mounted. For each database instance on your server add a section like below:
-
-----
-
-orcl.world =
-(DESCRIPTION =
-(ADDRESS_LIST =
-(ADDRESS =
-(COMMUNITY = tcp.world)
-(PROTOCOL = TCP)
-(Host = <INSERT HOST NAME OF SERVER HERE> )
-(Port = 1521)
-)
-(ADDRESS =
-(COMMUNITY = tcp.world)
-(PROTOCOL = TCP)
-(Host = <INSERT HOST NAME OF SERVER HERE> )
-(Port = 1526)
-)
-)
-(CONNECT_DATA = (SID = ORCL)
-)
-)
-
-----
-
-
-!!4.2 listener.ora
-
-
-
-The listener.ora file contains the descriptions of the services that other machines are allowed to connect to and any configuration that is required for the server listener.
-
-
-It contains sections for the listener name, listener address, databases served by the listener and configuration parameters.
-
-
-Here is an example:
-
-----
-
-# Name of listener and addresses to listen on
-LISTENER =
-( ADDRESS_LIST =
-(ADDRESS =
-(PROTOCOL=tcp)
-(HOST=<INSERT HOST>)
-(PORT=1521)
-(COMMUNITY=UK_SUP_TCPIP)
-)
-(ADDRESS =
-(PROTOCOL=ipc)
-(KEY=700)
-(COMMUNITY=UK_SUP_TCPIP)
-)
-)
-# List of services served by this listener
-SID_LIST_LISTENER=
-(SID_LIST=
-(SID_DESC=
-(SID_NAME=orcl)
-(ORACLE_HOME=/home/oracle/7.3.3..)
-)
-)
-# Start of configuration parameters.
-TRACE_LEVEL_LISTENER=OFF
-TRACE_FILE_LISTENER = "listener"
-LOG_FILE_LISTENER = "listener"
-CONNECT_TIMEOUT_LISTENER = 10
-STOP_LISTENER = YES
-DBA_GROUP = dba
-
-----
-
-
-!!4.3 sqlnet.ora
-
-
-
-The sqlnet.ora file contains configuration for the particular node of the network. This is independent of the number of databases or the number of listeners. The most important thing in this file is the Dead Connection Timeout configuration variable.
-
-
-Dead connection timeout checks every incoming process to a database instance and ensures that the client end of it is still responding. If the client (of whatever type) is not responding then the Oracle server shadow process is killed.
-
-
-This is very useful if you have many clients accessing a database, especially during a developmental phase when those clients are more likely to be failing to exit cleanly from the Oracle database.
-
-
-Below is a copy of my own sqlnet.ora file for you to puruse:
-
-----
-
-TRACE_LEVEL_CLIENT = OFF
-sqlnet.expire_time = 30 # The number of seconds between client checks.
-names.default_domain = world
-name.default_zone = world
-
-----
-
-
-
-
-
-!!4.4 Starting and Stopping the Listeners
-
-
-
-Now that the configuration of the listeners and SQL*Net is complete we can attempt to connect to the database using the networking software. (Before we were using direct links to the database, whereas here we are simulating a connection from a remote client machine).
-
-
-To start the listener using the above configuration:
-
-----

-
-
-
-If you have a DNS setup which doesn't return the IP address for the hostname specified then starting and stopping the listener can take some time (2-3 mins. dependant on the DNS timeout variable). If this is the case, don't worry, be patient.
-
-

-
-
-
-----
-
-!!5. Client Configuration
-
-!!5.1 Windows Clients
-
-
-
-SQL*Net configuration on the PC using newer versions of the Oracle Client Software is very easy. The best (and easiest) way of achiving a fully working client installation is to use the SQL*Net Easy Configuration tool supplied by Oracle.
-
-
-This toolhas a wizard type interface to take you through the installation of the tnsnames.ora and sqlnet.ora files.
-
-
-Select "Add Database Alias" and enter a name for the alias when prompted. This alias is the name you will refer to the database instance as, and as such should be the same as the instance name (orcl in this case).
-
-
-Select TCP/IP as the protocol, and when prompted the hostname of the machine hosting the database and the instance name of the database.
-
-
-That's it.
-
-
-However, if you do not have the SQL*Net Easy Configuration Tool then don't worry. You can simply create the tnsnames.ora and the sqlnet.ora files in the $ORACLE_HOME/network/admin directory on the client exactly as they are on the server. This will provide an alias the same as on the server (always a good idea anyway).
-
-!!5.2 Unix Clients
-
-
-
-UNIX clients are not very different that windows clients. If you have the Network Manager from Oracle then user that in the same way as above, if not then you can, again, just use the same configuration files as the server in the $ORACLE_HOME/network/admin directory.

-!!6. Automatic Startup and Shutdown
-
-!!6.1 dbstart & dbstop
-
-
-
-The automatic startup and shutdown of the Oracle database can be achieved (in 7.3.3..) with the files dbstart and dbshut both provided by Oracle. These files rely on the existance of the file /etc/oratab to work (although by altering the dbshut and dbstart files this can be moved).
-
-
-The format of the /etc/oratab file is as follows:
-
-----
-
-SID:ORACLE_HOME:AUTO
-
-----
-
-
-
-An example:
-
-----
-
-orcl:/home/oracle/7.3.3..:Y
-leaveup:/home/oracle/7.3.2.1.:N
-
-----
-
-
-!!6.2 init.d & rc.d
-
-
-
-To start and stop the database when the machine comes up and goes down by modifying the startup routines for the Linux machine. This is quite easy, although I should point out here that this may change depending on which flavour of Linux (slackware, debian, redhat, etc). I will show examples which work for Redhat Linux 5.. To modify these for your own flavour of Linux, please see your Linux documentation sets. (Although it should hold true for any Sys V type UNIX).
-
-
-Firstly, we need to create the script which will run dbshut and dbstart in the /etc/rc.d/init.d directory. Create the following file as /etc/rc.d/init.d/oracle:
-
-----
-
-#!/bin/sh
-#
-# /etc/rc.d/init.d/oracle
-# Description: Starts and stops the Oracle database and listeners
-# See how we were called.
-case "$1" in
-start)
-echo -n "Starting Oracle Databases: "
-echo "----------------------------------------------------" >> /var/log/oracle
-date +"! %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle
-echo "----------------------------------------------------" >> /var/log/oracle
-su - oracle -c dbstart >> /var/log/oracle
-echo "Done."
-echo -n "Starting Oracle Listeners: "
-su - oracle -c "lsnrctl start" >> /var/log/oracle
-echo "Done."
-echo ""
-echo "----------------------------------------------------" >> /var/log/oracle
-date +"! %T %a %D : Finished." >> /var/log/oracle
-echo "----------------------------------------------------" >> /var/log/oracle
-touch /var/lock/subsys/oracle
-;;
-stop)
-echo -n "Shutting Down Oracle Listeners: "
-echo "----------------------------------------------------" >> /var/log/oracle
-date +"! %T %a %D : Shutting Down Oracle Databases as part of system down." >> /var/log/oracle
-echo "----------------------------------------------------" >> /var/log/oracle
-su - oracle -c "lsnrctl stop" >> /var/log/oracle
-echo "Done."
-rm -f /var/lock/subsys/oracle
-echo -n "Shutting Down Oracle Databases: "
-su - oracle -c dbshut >> /var/log/oracle
-echo "Done."
-echo ""
-echo "----------------------------------------------------" >> /var/log/oracle
-date +"! %T %a %D : Finished." >> /var/log/oracle
-echo "----------------------------------------------------" >> /var/log/oracle
-;;
-restart)
-echo -n "Restarting Oracle Databases: "
-echo "----------------------------------------------------" >> /var/log/oracle
-date +"! %T %a %D : Restarting Oracle Databases as part of system up." >> /var/log/oracle
-echo "----------------------------------------------------" >> /var/log/oracle
-su - oracle -c dbstop >> /var/log/oracle
-su - oracle -c dbstart >> /var/log/oracle
-echo "Done."
-echo -n "Restarting Oracle Listeners: "
-su - oracle -c "lsnrctl stop" >> /var/log/oracle
-su - oracle -c "lsnrctl start" >> /var/log/oracle
-echo "Done."
-echo ""
-echo "----------------------------------------------------" >> /var/log/oracle
-date +"! %T %a %D : Finished." >> /var/log/oracle
-echo "----------------------------------------------------" >> /var/log/oracle
-touch /var/lock/subsys/oracle
-;;
-*)
-echo "Usage: oracle {start|stop|restart}"
-exit 1
-esac

-
-
-It is worth checking that this file actually correctly stops and starts the databases for your system. Check the log file, /var/log/oracle for error messages.
-
-
-Once this script is working we need to create start and kill symbolic links in the appropriate runlevel directories /etc/rc.d/rcX.d.
-
-
-The following commands will ensure that the databases will come up in runlevels 2,3 and 4:
-
-----
-
-$ ln -s ../init.d/oracle /etc/rc.d/rc2.d/S99oracle
-$ ln -s ../init.d/oracle /etc/rc.d/rc3.d/S99oracle
-$ ln -s ../init.d/oracle /etc/rc.d/rc4.d/S99oracle
-
-----
-
-
-
-To stop the databases on reboot or restart we need the following links:
-
-----
-
-$ ln -s ../init.d/oracle /etc/rc.d/rc0.d/K01oracle # Halting
-$ ln -s ../init.d/oracle /etc/rc.d/rc6.d/K01oracle # Rebooting

-!!7. Other Bits
-
-!!7.1 Intelligent Agent
-
-
-
-If you have a need for the Oracle Intelligent Agent, I found that you can run it without any configuration changes. To start the IA try:
-
-----
-
-$ lsnrctl dbsnmp_start
-
-----
-
-
-
-To stop the IA try:
-
-----
-
-$ lsnrctl dbsnmp_stop
-
-----
-
-
-
-There do not appear to be any messages indicating a sucessful or otherwise start or stop of the intelligent agent. However, the IA responded to Enterprise manager on the client side so I can only assume that it is working.

-
-!!8. Troubleshooting
-
-
-See below for various troubleshooting hints.
-
-!!8.1 I cannot create a database when using Oracle 7.2.x.
-
-
-
-The files shipped by Oracle in the 7.2.x product are incorrect in assuming that you want to setup a parallel server configuration. The shipped init.ora file has the following line in it:
-
-----
-
-# define parallel server (multi-instance) parameters
-ifile = ora_system:initps.ora
-
-----
-
-To fix the problem simply comment it out:
-
-----
-
-# define parallel server (multi-instance) parameters
-#ifile = ora_system:initps.ora
-
-----
-
-
-!!8.2 I'm getting segmentation faults in svrmgrl under version 7.3.4.x.
-
-
-
-I've had this problem reported to me by a number of people. Gerald Weber gerald_weber@master.co.at solved it:
-
-----
-
-Hi Paul,
-first of all thanks for your help,but none of the possible problems you are
-thinking about were responsible for my problem.
-The problem is the iBCS-emulator itself.
-It seems that Oracle performs an sysconf-calls which isn't supported in the
-current version of iBCS.
-Look at the trace :
-<7>
[[22
]615 sysconf(34)
-<7>iBCS2 unsupported sysconf call 34
-<7>[[22]615 sysconf error return linux=-22 -> ibcs=22 <Invalid argument>
-<7>[[24]615 sysconf(34)
-<7>iBCS2 unsupported sysconf call 34
-<7>[[24]615 sysconf error return linux=-22 -> ibcs=22 <Invalid argument>
-Solution: patching the iBCS-source.apply the following diff-pach :
---- sysconf.c Sun Apr 19 19:19:15 1998
-+++ sysconf.c.ori Sun Apr 19 19:28:45 1998
