hello,
  our SAP instance is going to Google Cloud - we installed TWS agent on the SAP instance and pointed our existing workstation to that address. Looks like we had to create a new user for that agent and not the user tws930 we normally use- so now when i run a job in the existing workstation that is pointed to the cloud - we get internal abend because the user calling the job is wrong ?... i changed the login user to that new user in the job definition and it runs. is there anyway to do a mass change to all the job definitions and change the login user to be the new one. we have 500 jobs :)

As an example, if your existing workstation is called ABC123 you could do the steps below, but always test the procedure first.

# Create a text file of all jobs defined against workstation ABC123
composer 'create allABC123Jobs.def from job=ABC123#@'
# Globally replace all instances of the tws930 user with the value of the new user
sed s'\STREAMLOGON tws930\STREAMLOGON thenewuser\'g allABC123Jobs.def > allABC123JobsNew.def
# Use composer to validate the file with the new amended STREAMLOGON user
composer 'validate allABC123JobsNew.def'
# Replace the job definition in the database with the ones from the file
composer 'replace allABC123JobsNew.def'
