Installation of ORACLE V 7.0.16.4.0 for SCO Unix on Linux V 1.2.1

Prerequisites

Linux kernel: You didn't expect this!
make: We have a GNU make with Linux.
iBCS2 emulator V 1.2-950308: Allows to run binaries from other Unix systems on Linux. I had this software in my Linux distribution in diskzc1 (german S.u.S.E. distribution based on Slackware). You must recompile this, if you built a new kernel.
five SCO Unix executables:
/bin/idar (archiver)
/bin/idas (assembler)
/bin/idld (linker)
/lib/idcpp (preprocessor)
/lib/idcomp (compiler): Get them, where you can, they are required for installation only.
200MB space in /usr/local/oracle7: This includes the RDBMS, SQL*Plus, SQL*Net TCP V1 and V2, common files, the installer, the stage area, messages for all languages and the default database. With some care, it may be possible to reduce space requirement to about 120 MB.

Problems during installation

Main problems were:

The install procedure did not make the scripts and executables executable, the mount of the CD under Linux left permissions as 444, no RockRidge extension (?)
The installer does not catch all errors, especially when attempting to compile and link libraries. One must carefully examine the install.log.
It took some time and experiments to figure out that for an easy installation the SCO executables are required. As an alternative, one must generate gcc, ld, as ... for SCO systems and use them instead. This should be possible, but I had the chance to use the idxx programs.

# now install the wanted executables

# again select 'Install/Upgrade/Patch Software Only',
# then 'Install from Permanent Staging Area'
# and then 'ORACLE7 Distributed Database option 7.0.16'
# plus 'ORACLE7 Procedural Option (PL/SQL V2) 2.0.'
# plus 'ORACLE7 Server (RDBMS) 7.0.16.4.0'
# optionally you may select i.e. SQL*Plus, SQL*Net TCP/IP V1 and/or V2
# answer other questions, don't require relinking,
# say yes to 'Would you like to install TCP/IP Protocol Adapter (V2)?'.
# The installation now should take place without any serious error.
# Examine $ORACLE_HOME/orainst/install.log again
# (ignore install.log error '/usr/local/oracle7/bin/gennttab: [:
# too many arguments')
#
# Now you are ready to create a database. Leave the installer,
# move install.log elsewhere and restart the installer again with
 
orainst
 
# After the initial questions select 'Create New Database Objects',
# enter/confirm the System Identifier (ORACLE_SID) and you will
# (surprisingly for normal, not ORACLE proven people) again see
# the main window with 'available products' and 'installed products'.
# Select the point 'ORACLE7 Server (RDBMS) 7.0.16.4.0' and install.
# You are asked for some passwords and names/sizes of database
# files. Accept them for a first test, and then the creation of the
# database is done. You may want to have a second window open
# with a 'cd $ORACLE_HOME/orainst; tail -f install.log' to see,
# what's going on, but don't be surprised to find about 235 SQL
# errors, when the data dictionary is created. The scripts always
# do something like: 'drop table ...; create table ...' to be shure,
# the table can successfully be created, but the drop gives an error,
# because on an initial run the table does not exist.
# After the installer tells you about success and leaving the installer,
# you may check the log with:
grep ORA- install.log|grep -v ORA-00942|grep -v ORA-01432|grep -v ORA-01434
# you then should get this list of SQL errors:

# I did not check, if this are serious errors until now, because
