please, where can I download TAC?? it's not an open source ??
is there any way Schedule the Jobs without using TAC??
Talend Administration Center will be available in talend subscription solution not open source.
With talend open source, you can export the job script, and then schedule it with third scheduler tool, such as crontab command on Linux.
Please take a look at this online document about:TalendHelpCenter:How to build Jobs
The Build Job feature allows you to deploy and execute a Job on any server, independent of Talend Studio.
