Oracle 19c - patch 19.22 unavailability for Windows platform

 Oracle 19c - patch 19.22 unavailability for Windows platform 

Having upgraded the Oracle 11g 11.2.0.4 database to Oracle 19c 19.3.0.0.0 while applying the latest patch 19.22 discovered that 19.22 patch is still not released for the Windows platform, raised a SR with Oracle support and they confirmed that 19.22 patch for Windows platform is yet to be released, and they have requested the internal development team to release the 19.22 patch for Windows platform, hope it helps for the shops which are trying to do the latest set of patches 19.22 for their databases on Windows platform.

 Oracle 11g 11.2.0.4  upgrade to Oracle 19c 19.3.0.0.0  failing with error ORA-01034

Solution:

glogin.sql file is causing something that upgrade would fail with error ORA-01034, the simple solution is to rename the glogin.sql file and re-run the upgrade process and it will catch up from the point it failed, hope it helps.

Error: Error reading domain:

60820: This domain is a managed domain. It has been scaled out from the original domain.

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.
