Database Listener Configuration

If we need to configure database listener go to $ORACLE_HOME/lib and execute shell called netca

Create new Database

Solving compilation/link errors

Some issues should appear during installation.
If you have not created the symbolic links above, you will have to solve error lib//libagtsh.so: undefined reference to `nnfyboot' in make: rdbms/lib/dg4odbc] Error 1. For this, create the symbolic links and execute the commands:
export ORACLE_HOME=/opt/oracle/Oracle11gee/product/11.2.0/dbhome_1
cd $ORACLE_HOME/lib
ln -s libclient11.a libagtsh.a
$ORACLE_HOME/bin/genagtsh $ORACLE_HOME/lib/libagtsh.so 1.0


Now we will encounter many errors due to indirect library linking:
To solve error # libnnz11.so: could not read symbols: Invalid operation /sysman/lib/ins_emagent.mk, enter the command:
export ORACLE_HOME=/opt/oracle/Oracle11gee/product/11.2.0/dbhome_1
sed -i 's/^\(\s*\$(MK_EMAGENT_NMECTL)\)\s*$/\1 -lnnz11/g' $ORACLE_HOME/sysman/lib/ins_emagent.mk

To solve error # nsglsn.c:(.text+0xc29): undefined reference to `ons_subscriber_close' /network/lib/ins_net_server.mk, enter the command:
sed -i 's/^\(TNSLSNR_LINKLINE.*\$(TNSLSNR_OFILES)\) \(\$(LINKTTLIBS)\)/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/network/lib/env_network.mk
To solve error # libocrutl11.so: undefined reference to `lfifcp' rdbms/lib/ins_rdbms.mk, enter the commands:
sed -i 's/^\(ORACLE_LINKLINE.*\$(ORACLE_LINKER)\) \(\$(PL_FLAGS)\)/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/rdbms/lib/env_rdbms.mk

You also need to execute the following commands to prevent from later errors:
sed -i 's/^\(\$LD \$LD_RUNTIME\) \(\$LD_OPT\)/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/bin/genorasdksh
sed -i 's/^\(\s*\)\(\$(OCRLIBS_DEFAULT)\)/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/srvm/lib/ins_srvm.mk

Starting up the database

Once your server have been restarted, your database may not start. To solve this issue, first check in /etc/oratab that it has the 'Y' flag, if not, set it.
sudo gedit /etc/oratab

And replace N by Y
orcl:/opt/oracle/Oracle11gee/product/11.2.0/dbhome_1:Y

Manually starting up the database

Finally, to manually start Oracle, run these commands as oracle user
dbstart $ORACLE_HOME

Manually shutting down the database


dbshut $ORACLE_HOME
