Oracle Database HOWTO: Troubleshooting

## 8. Troubleshooting

See below for various troubleshooting hints.

## 8.1 I cannot create a database when using Oracle 7.2.x.

The files shipped by Oracle in the 7.2.x product are incorrect in assuming that you want to setup a parallel server configuration. The shipped `init.ora` file has the following line in it:

> `

>     # define parallel server (multi-instance) parameters
>     ifile = ora_system:initps.ora

> `

To fix the problem simply comment it out:

> `

>     # define parallel server (multi-instance) parameters
>     #ifile = ora_system:initps.ora

## 8.2 I'm getting segmentation faults in `svrmgrl` under version 7.3.4.x.

I've had this problem reported to me by a number of people. Gerald Weber `gerald_weber@master.co.at` solved it:
