Home -> Community -> Usenet -> c.d.o.server -> second set of eyes needed - db not registering nor getting dispatchers for shared server
Platform: Oracle 9.2 on Solaris 5.9
Recently started getting problems on a dev db of maxing out 'processes.' Made the decision to enable shared server, so added 'dispatchers' init parm, fiddled with shared pool and large pool sizes. When this all seemed to check out I replicated the same changes to qa, pre-prod and prod databases and to a set of dev/qa/pre-prod/prod 'sister' db's that live on another net.
All but one of a total of 8 distinct db (and that one is one of the two prod db's) are showing mts dispatchers and shared server connections. The one db is still showing nothing but dedicated connections, and the listener is not reporting anything from dynamic registration.
>From eyballing the init.ora (we're not yet using spfiles on these), sqlnet.ora, and listener.ora files, I found only one difference bet. the 'bad' db, and all the 'good' ones. That was in the listener.ora, where the bad server listed host by ip address, and all the good ones listed by server name, but when I substituted IP address for server name on one of the test servers, restarted the listener and did ALTER SYSTEM REGISTER, the problem did not reproduce. Listener status shows only one 'unknown' service handler (from the specific SID list in listener.ora), and listener services doesnt' show any dispatcers.
Here is the listener config from listener.ora file (masked the ip
address)
$>: cat listener.ora
# LISTENER.ORA Network Configuration File:
/u01/app/oracle/product/9.2.0/network/admin/listener.ora
# Generated by Oracle configuration tools.
#-----------------------------------------------------------------------

and the sqlnet.ora file:

$>: cat initVITXP01.ora
