After activating ATAP successfully, you do not see SSL encrypted traffic with Oracle

Troubleshooting


Problem

You have configured ATAP and successfully run "activate".  The messages are similar to below:
...
Inserted instrumentation
Restoring non-instrumented libn12.a from /opt/oracle/12.2.0/lib/libn12.a-guard-original
Restoring non-instrumented libnnzst12.a from /opt/oracle/12.2.0/lib/libnnzst12.a-guard-original
Restoring non-instrumented libnnz12.a from /opt/oracle/12.2.0/lib/libnnz12.a-guard-original
Restoring non-instrumented naeet.o from /opt/oracle/12.2.0/lib/naeet.o-guard-original
Restoring non-instrumented oracle /opt/oracle/12.2.0/bin/oracle-guard-original -> /opt/oracle/12.2.0/bin/oracle
Instance root/myinst1 is instrumented
Set 856 bytes for 'executor/env' in file '/opt/oracle/12.2.0/bin/oracle-guard-executor'
Instance root/myinst1 is active

The guardctl commands list-active shows the instance.  
But no encrypted traffic is seen in Guardium. 

Cause

Encryption is set to 1 in the STAP configuration.  This was done either in the GUI (S-TAP Control > Inspection Engine > encryption box checked) or in the guard_tap.ini (encryption=1) or both. 
 

Diagnosing The Problem

In the STAP syslog, you see configuration errors similar to the ones below when the STAP is started:
Guardium STAP starting, Wed May 20 10:14:48 2020
(pid 6946830,uid 0)
FIPS 140-2 mode not available
2020.05.20 10:14:49 Adding exec map for /opt/oracle/12.2.0/bin/oracle-guard-instrumented failed!
2020.05.20 10:14:49 CONF_ERROR: IPC reader failed to initialize Adding exec map for /opt/oracle/12.2.0/bin/oracle-guard-instrumented failed!, ktap_install is set to 0, no data will be captured from KTAP
2020.05.20 10:14:49 CONF_ERROR: After failed to initialize IPC, Initailize PCAP failed: , no data will be captured from PCAP

Resolving The Problem

  • Stop the database processes.
  • Deactivate ATAP.
  • Set encryption=0.  It should not be set in either guard_tap.ini or S-TAP Control. 
  • Restart STAP.  Verify after the restart that encryption is still 0 in both guard_tap.ini and the GUI and KTAP_INSTALLED=1. Reset the KTAP setting if needed. 
  • Activate ATAP.
  • Start the database processes.
