Primavera gave ORA-12545:Connect failed because target host or object does not exist.

A fellow me and said he got the error below after installing Oracle Primavera P7:

ORA-12545:Connect failed because target host or object does not exist.

I asked him to remove Oracle 10g Express Edition and Oracle Primavera P6 Ver 7, then reinstall again, the problem got fixed.

This error is usually caused by the host setting in both tnsnames.ora and listener.ora. If ip address is used rather hostname, this issue should go away.
