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

---

---

# 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:

Hi Paul,

first of all thanks for your help,but none of the possible problems you are
thinking about were responsible for my problem.
The problem is the iBCS-emulator itself.
It seems that Oracle performs an sysconf-calls which isn't supported in the
current version of iBCS.
Look at the trace :

<7>[22]615 sysconf(34)
<7>iBCS2 unsupported sysconf call 34
<7>[22]615 sysconf error return linux=-22 -> ibcs=22 <Invalid argument>
<7>[24]615 sysconf(34)
<7>iBCS2 unsupported sysconf call 34
<7>[24]615 sysconf error return linux=-22 -> ibcs=22 <Invalid argument>

Solution:  patching the iBCS-source.apply the following diff-pach :
