Hello everyone,

I am facing a very strange problem in one of our Linux (5.3) environment. It has a oracle 11g R2 client installed. I have a simple C++ program which uses olog() oci function to connect to a remote database using the client. when I execute the program it gives a segmentation fault on olog() function,below is the error stack:

Program received signal SIGSEGV, Segmentation fault.
0x00002aaaaf00eae2 in kpuhhalp () from /oracle/112/lib/libclntsh.so.11.1

#10 0x00002aaaafacdd47 in olog () from /oracle/112/lib/libclntsh.so.11.1

But on the other hand when I use OCILogon() function of OCI8 under same conditions it goes fine.

I am not able to think on whether this is a problem due to incorrect/incomplete installation of oracle client, or some thing else. Just to confirm I have re-installed the oracle 11g client but even then problem exists.

Please help me in resolving this.

Thanks,
Manish

Been way too many years and versions since I dealt with this sort of
thing, but I'd guess you have either an include statement with a typo
in your program, or somehow you are setting off something that isn't
found in older versions, perhaps a sqlnet.ora issue. Maybe sqlnet
tracing could help.

Hi,

I have had the same issue.
Please choose Oracle DB client 11.2.0.2 instead of 11.2.0.1 and your problem will get fixed.
