I am not able to start the integration server
please see the wrapper log
You need to provide us with the server.log and not the wrapper log.
You can find it in <SAG_HOME>/IntegrationServer/instances/default/logs
Please check if your license is valid, if license is valid.
Then check for enough space available in you installation drive.
The same scenario happened with me …… once due to license issue and 2nd time due to space issue.
Please note that invalid license will still allow IS to be up and running for 30 minutes. It appears to be something else, as @John_Carter4 mentioned, please share default/logs as well as profiles/IS_default/logs.
