APAR information on WCS

versioninfo.sh file will provide you the feature pack fix pack information about your WCS installation. But how to get the APAR installed in a particular WCS installation? There are couple of ways you can check this

• historyInfo.sh file will provide you all the installation/uninstall information about the fix pack feature pack and APARs
• The file NIFStack.xml will contain the information about the apars installed. The location of the file is /instances//properties/version/update/backup/NIFStack.xml.
• More information about the APAR installation will be there in /logs/update/APAR_name.install 

 

IHS Access Log for WebSphere Commerce sites

While doing the production server trouble shooting for many of the issues, the investigation starts from the IHS access logs. But the default IHS log configuration will not give you enough details for troubleshooting and diagnose the root cause server. It will be more complicated when there is a cache layer exists as well. The following log level will give you all the information needed for trouble shooting. The log will provide the output in a csv format so that it will be easier for further processing if needed

LogFormat  "\"%h\",\"%{%Y-%m-%d-%H.%M.%S.000000}t\",%p,\"%H\",\"%m\",\"%U\",\"%q\",%>s,\"%b\",\"%{WAS}e\",%D,\"%{CACHED_RESPONSE}o\"" common

h - Client IP
t - Access Time
p - Port
H - Protocol
m - Request method
U - URL without query String
q - Query String
>s - Status of the request
b - size of response in bytes
{WAS}e - Name of the WAS server
D - Time taken to serve request in micro seconds
{CACHED_RESPONSE}o - The request served from dyna cashe or not

If we want to shoe the request and response cookie values then we could use the following parameter for a short period of time

{Cookie}i - Cookie request header
{Set-Cookie}o - Cookie with response
