<div>We are deploying Hermes server here in a UNIX environment and java containers with Oracle database.</div> <div> </div> <div>I have a question regarding this (see below) - I'm assuming that the Oracle will control the record access and so on - so this comes down to architecturally if Hermes can handle this - eg - adding new entries to the transaction queue, etc, each instance should be OK since the table record locking will return unique results and prevent one instance tripping up another.</div> <div> </div> <div>Anyone tried this already or have thoughts? </div> <div> </div> <div>I know part of this will be improved using Hibernate - but we'd like to do this right away this month - and then upgrade to the Hibernate version when its available.</div> <div> </div> <div>All feedback appreciated.</div> <div> </div> <div>Thanks, DW<BR></div> <BLOCKQUOTE style="PADDING-LEFT: 8px; MARGIN-LEFT: 8px; BORDER-LEFT: blue 2px solid"> <DIV class=Section1> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">What we need to do is have different containers (and thus different instances of Hermes, with different connections to the database) run concurrently, pointing to the same set of Hermes message tables.</SPAN></FONT><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></P> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"> </SPAN></FONT><o:p></o:p></P> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">So the question is, can multiple instances of Hermes, in different containers point to the same database tables (ie, same user id, two containers pointing to the same message queue/audit tables in the Hermes schema.
