whether there is an invalid connection that should be terminated. It finds the dead connections and returns an error, causing the server process to exit.

Additional steps for Oracle 9i RDBMS:

Some Oracle 9i the Oracle Installers create symbolic links in the client library directory /oracle/client/92x_64/lib that reference to SID-specific libraries residing in the $ORACLE_HOME/lib of that database instance. This causes trouble when the database package is not running locally - these symbolic links can not be resolved. Therefore these links are required to be resolved, i.e. copied locally in the client library directory.

But only copying the client libraries locally does not solve the issue completely: certain client libraries are linked during installation so that the 'shared dynamic path search' contains the following entries (chatr output):

LD_LIBRARY_PATH enabled first

SHLIB_PATH enabled second

embedded path enabled third /oracle/<SID>/920_64/lib

This means if the libraries are not found in LD_LIBRARY_PATH or SHLIB_PATH, the dynamic loader again searches in the instance specific path $ORACLE_HOME/lib. To resolve this issue, the needed libraries have to be provided either in LD_LIBRARY_PATH or SHLIB_PATH as local copies or symbolic links. For example create symbolic links to these libraries in the central executable directory /sapmnt/<SID>/exe is a possible solution.

Additional steps for Oracle 10g RDBMS:

Even though no cluster services are needed when installing a Oracle 10g Single Instance, the cluster services daemon ($ORACLE_HOME/bin/ocssd.bin) is installed. It will remain running, even when the database is shut down. This keeps the file system busy during package shut down. Therefore it is mandatory that the cluster services daemon is disabled.

Comment or remove the following entry in /etc/inittab:

# h1:3:respawn:/sbin/init.d/init.cssd run >/dev/null 2>&1 </dev/null Additionally there is a init script in /sbin/init.d:

/sbin/init.d/init.cssdthat is linked to by /sbin/rc3.d/S<###>init.cssd

and

/sbin/rc3.d/K<###>init.cssd

Remove the following referenced links to prevent the Oracle Cluster Services Daemon from initiating during boot time.

#rm /sbin/rc3.d/S<###>init.cssd

#rm /sbin/rc3.d/K<###>init.cssd

Additional Steps for MAXDB

Logon as root to the primary host of the database where the db or dbci package is running in debug mode.

MAXDB Database Step: SD930

If environment files exist in the home directory of the MAXDB user on the primary node, create additional links for any secondary.

For example:

su - sqd<sid>

ln -s .dbenv_<primary>.csh .dbenv_<secondary>.csh

ln -s .dbenv_<primary>.sh .dbenv_<secondary>.sh

exit
