Dears First I would like to thank you all for replies about tracing - it helped me very much Now I have a different problem - I have Linux (suse 7.0) with oracle 8.1.7EE and with 2 IP addresses and I want to have MTS server running. The server allways connects to the listener as a dedicated server and not as dispatcher (lsnrctl services). I have opened TAR but they are not able to help me (TAR opened since 18.6). I have tried a lot of things in init<SID>.ora and listener.ora files but it didnt help. Is there somebody who has the same configuration and whith MTS running? If yes, would you be so kind and send me your configuration files (or part with MTS config), please? Thank you in advance Ivo this is my MTS part of init.ora file #mts_max_dispatchers=10 #mts_max_servers=10 #mts_servers=3 #mts_listener_address="(ADDRESS=(PROTOCOL=TCP)(HOST=10.17.150.5)(PORT=1521)) " #large_pool_size = 10000000 #MTS_DISPATCHERS="(ADDRESS=(PARTIAL=TRUE)(PROTOCOL=TCP)\ #(HOST=10.17.150.5)(PORT=12345))(DISPATCHERS=2)" mts_servers=3 mts_dispatchers="(PRO=TCP)(DISP=3)(LIS=awms)" -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Libal, Ivo INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
