DB job to generate/email Oracle report output

The task is to have an Oracle report generated daily, automatically, and e-mailed to a user.

So I've sort of got this working (it works if I hardcode one of the reports server names below).

I created a job on the database that will generate the report. I'm able to get the report to email as a PDF to the destination with this command:

UTL_HTTP.REQUEST('http://server/reports/rwservlet?server=specific_report_server &report='||p_report_name||'&userid='||p_connstring||'&destype=mail'||p_parameters||'&desname='||p_to_recipientlist||' &cc='||p_cc_recipientlist||'&bcc='||p_bcc_recipientlist||'&subject=%22' || REPLACE(p_subject,' ','%20') || '%22&paramform=no&DESformat=pdf&ENVID='||p_envid);

That works great...

The problem however is that my organization has two report servers that are load balanced. Our server team could take down one of the servers without really any warning, so I can't just hardcode the report server name (the ?server= parameter above) with one of the report server names because it will work for a while, then when that server goes down, it will stop working.

My server team asked me to look for a way to pull the server from the formsweb.cfg file or from default.env value within the job (there are parameters in there that hold the server name). The idea there is that the "http://server" piece will direct the report to be run on the appropriate server, and the first part of the job could get the reports server name from the config file that the report is run on. I'm not sure if this is possible from the database level, or how to do this. Any ideas?

Is there a better way that this can be done, perhaps?

If there are two load-balanced servers, that strongly implies that the network folks must have configured some sort of virtual IP (VIP) for the service. You (and everyone else) should be using that VIP rather than a specific server name.

For example, if you have two servers reportA.yourdomain.com and reportB.yourdomain.com, you would almost certainly create a VIP for reports.yourdomain.com that load balances between the two servers (and knows whether one of the servers is down or whether a new reportC server has been added). This VIP would either do the load balancing itself or would point to an actual physical load balancer that distributes the traffic. All applications would reference the reports.yourdomain.com VIP rather than any hard-coded server names.
