agentres jar file on collector

Hi There,

I found agentres-<release numner> jar files under <DT_HOME>\collector\lib. The release numbers are include every release from 4.2 to 6.0. We are currently using dT60.

The question is what's those older version jar file for? Are they design for any older version bootstrap agent in environment? So it can be upgrade through release.

Thanks

YC

hi YC,

those agentres jars are not needed for bootstrapping, but exactly for the opposite scenario, when somebody is using a non-bootstrapped agent.

you will probably have noticed that those "older" agentres jars are much smaller than the current one. this is because they don't contain the "core" native agent which is required only in the most current version for bootstrapping.

however, if old versions (i.e. not bootstrapped) of the agent try to connect to this collector than the collector still needs to send it the java/.net/javascript code in the same version as the non-bootstrapped agent is. and that's what those agentres jars are for.

best,
Christian

Hi Christian,

Thanks for clarification. I also see those agentres files has most recent version. Are those just for z/OS agent?

Thanks

hi YC,

ok, my answer was not a 100% correctly formulated, it should have been:

those old agentres jars are not needed for bootstrapping,...
however, the current agentres jar is of course needed for bootstrapping

this should answer your question, right?

I don't see the connection to z/OS, however. you can also look into the jars and see that in the current one there's basically every native agent for every platform, including z/OS.

best,
Christian
