Error -349 - Informix /Tuxedo

Hi all, Actually, I'm working with Tuxedo and Informix, all servers are connected with Informix whit the sentence DATABASE: tpsvrinit() { EXEC SQL DATABASE ladasoft; if(sqlca.sqlcode < 0) { ReportaErr("TPSRVINIT","Al Ejecutar el DATABASE",sqlca.sqlcode,"DATABASE itrofcfalla"); } } After time, the servers are disconnected and appears the -349 error. What happens? It could be indexes? is the query? is the session dead (I don't know the diference between DATABASE / CONNECT) ? For example, a server that use to be disconnected has this code: sprintf(squery,"select UNIQUE PIC.telefono_pisa, PIC.item, CAT.desc_item, CAT .nivel from pic@des:sereqp PIC, lada:items_internet CAT where PIC.item = CAT.item and PIC.telefono_pisa in (select AG.telefono_pisa from pic@des:agrupado AG where AG.tel_fact_pisa = '%s' and AG.status = '0') order by pic.telefono_pisa, cat.nivel desc",sTel); EXEC SQL PREPARE det_com_qa from :squery; if (sqlca.sqlcode != 0) { userlog("Error en PREPARE sqlcode=%d",sqlca.sqlcode); tpreturn(TPFAIL, 0,val, 0L,0); } In the ulog appers: 180135.k460!ladasoft14.5851: Error SELECT -349 Thanks in advance, * Sent from RemarQ http://www.remarq.com The Internet's Discussion Network * The fastest and easiest way to search and participate in Usenet - Free!
