Install database software

Let’s start with database software installation as oracle user.

su - oracle

Unzip the  database  install files:

[oracle@ora-c7 ~]$ cd  database/
[oracle@ora-c7 database]$ ./runInstaller

During the linking phase, you will see the following error.

    Error in invoking target 'links proc gen_pcscfg procob' of makefile
    for details.

To fix it, do the following:

    rm -rf $ORACLE_HOME/lib/stubs/*
    cp $ORACLE_HOME/rdbms/lib/ $ORACLE_HOME/rdbms/lib/

Perform the following modifications:

vi $ORACLE_HOME/rdbms/lib/
    # Line 176
    # FROM:
    # TO  :

    # Line 279-280
    # FROM:
    # TO  :
    LINK=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS) $(COMPSOBJS) -Wl,--no-as-needed
    LINK32=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS32) $(COMPSOBJS) -Wl,--no-as-needed

    # Line 3041-3042
    # FROM:
    # TO  :
            $(LLIBTHREAD) $(LLIBCLNTSH) $(LINKLDLIBS) -lnnz12

Click the “Retry” button.
