Solution: 

Oracle Doc 2380467.1

This condition is a result of Bug 25964279 (internal / not published in MOS).  Due to Bug 25964279, the startComponent.sh and stopComponent.sh scripts can only successfully complete from the first node in an OID 12c collocated cluster.

 

Execute the startComponent.sh and stopComponent.sh scripts only from the first server node in the collocated cluster.

Alternately an OID instance may be started from a WLST session with one of the following commands :

WLST connected to the AdminServer:
start('<COMPONENT_NAME>')

WLST connected to the target NodeManager:
nmStart(serverName='<COMPONENT_NAME>',serverType='OID')

Replace '<COMPONENT_NAME>' with the OID component name, e.g. 'oid1' or 'oid2'

Done

Cause:

Oracle Support Document: 2723339.1

The issue was happening because the pack command is being run using -managed=true option on a domain that's already created using unpack command, as following:

     a. Host 1 has a WebLogic domain with Admin and a managed server - Execute pack command with -managed=true option.

     b. Host 2 - Execute unpack command.

     c. Host 2 - Execute pack command with -managed=true option.

     d. Host 3 - Execute unpack command and it will fail with 60820: This domain is a managed domain. It has been scaled out from the original domain

 Solution:

Do not extend a domain which is already created using unpack after it's pack was run using -managed=true option.

In order to extend a domain pack should be executed on the host where the domain was created originally using the config wizard or unpack was executed on a host after it's pack was run using -managed=false option

ASM instance warning message in alert log file

“Warning: VKTM detected a time drift”

  Solution

Usually VKTM and VKRM issues come together, at least when you are using the resource manager. 

The VTKM is the Virtual Keeper of Time Process. The VKTM acts as a time publisher for an Oracle instance.  VKTM publishes two sets of time: a wall clock time using a seconds interval and a higher resolution time (which is not wall clock time) for interval measurements.  

The VKTM process is a process that is available in ASM instances and RDBMS instances. So if you see issues with VKTM process, it usually pops up on both. VKTM usage is affected mainly by two hidden parameters _timer_precision and _disable_highres_ticks. So, tuning these parameters can bring down VKTM CPU consumption.

The VKRM process is the Virtual Scheduler for Resource Manager Process, and it serves as centralized scheduler for Resource Manager activity. As there is no resource manager on a ASM instance, you will see this process only on RDBMS instances.

For version 11.2.0.1, Apply patch for Bug 9843304.  This Bug is already fixed in 11.2.0.2

For 11.2.0.2 and 11.2.0.3, apply patch for Bug 11837095, This Bug is already fixed in 11.2.0.4

If patch is not available then please raise SR with Oracle Support.

Add the following even in spfile or pfile.

driver.  The following questions will determine whether the driver is

loaded on boot and what permissions it will have.  The current values

will be shown in brackets ('[]').  Hitting <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

openssl command hangs while generating .p12 file - Git Bash environment

openssl commands hangs while generating .p12 file - Git Bash environment 

 openssl command will remain hang if you are trying to generate the .p12 file from the SSL cert , the only option to come out of hung state is to use the Ctrl+C and it will not generate the .p12 file. 

The issue can be resolved to use the winpty before the openssl command and it will generate the .p12 file. 

$ openssl pkcs12 -export -in ssl_cert_file.crt -inkey ssl_crt_key_file.key -out ssl_cert_file.p12 -name "test command to generate the p12 file" 

Ctrl+C 

use the winpty command and it will work 

$ winpty openssl pkcs12 -export -in ssl_cert_file.crt -inkey ssl_crt_key_file.key -out ssl_cert_file.p12 -name "test command to generate the p12 file"

Resolution:

- check the /etc/hosts file, it should contain the fully qualified name of the host machine with the IP.

- update the /etc/hosts with the correct hostname / ip and Oracle Net Configuration Assistant will pick the right hostname and will get the listener port for the configuration.

- to make sure check the installer screen , also log file can be checked under "cfgtoollogs/netca"
