Symptoms

When trying to execute C program on Server - Oracle 11g 11.2.0.1 on

IBM AIX 64 bit, 6.1, the following error message is

received.

Application connects to Server with Oracle 11g

11.2.0.1:

ORA-24550 : signal received : [si_signo=11] [si_errno=0]

[si_code=50] [si_adr = 2020202020202020] killed

Depending on the Operating System the stack would

differ. For

example;

Linux x86-64 would be something

like;

/lib64/libpthread.so.0[0x3412a0673d]

/lib64/libc.so.6(clone+0x6d)[0x3411ed44bd] ORA-24550: signal

received: [si_signo=6] [si_errno=0] [si_code=-6] [si_int=0]

[si_ptr=0x200000000] [si_addr=0x1f400001c43]

Changes

Upgraded Database from Oracle 10g 10.2.0.1 to Oracle 11g

11.2.0.1

Cause

Diagnosability features which are turned on by default on Oracle

11g Release 2 causes the problem.

Parameters are:

DIAG_ADR_ENABLED

DIAG_SIGHANDLER_ENABLED

DIAG_DDE_ENABLED

Solution

1. Such errors can occur if the "Diagnosability" features are

'ON'.

To turn off the OCI signal handler and re-enable standard Operating

System failure processing, place the following parameter setting in

sqlnet.ora:

DIAG_SIGHANDLER_ENABLED=FALSE

By default this parameter is set to true.

If you want to see the old behavior you can simply turn off the

feature by placing the following parameter setting in your client

side sqlnet.ora file under $ORACLE_HOME/network/admin

directory.

2. In addition, please turn off other Diagnostics parameters as

well by placing the following entries in the client side or server

sqlnet.ora file. i.e., from where the application is

run.

DIAG_ADR_ENABLED=OFF

DIAG_SIGHANDLER_ENABLED=FALSE

DIAG_DDE_ENABLED=FALSE
