Hola Maria Antonieta buenas tardes Dudo mucho que el problema sea postgres Primero ve que el problema no se trate desde tu aplicacion web asegurate que este cerrando la transacción y que este cerrando la conexion cuando tu script termine de ejecutarse.
Para ver que procesos te estan generando el problema estos links pueden ayudarte https://wiki.duraspace.org/display/DSPACE/Idle+In+Transaction+Problem http://pg-promotor.blogspot.pe/2010/02/postgres-idle-in-transaction.html Respecto de tu archivo de configuracion parece que no has tocado nada y esta todo por defecto aqui tienes una guia rapida para configurar algunos valores https://wiki.postgresql.org/wiki/Mejorando_el_rendimiento_de_tu_Postgresql_Server saludos 2016-08-09 14:30 GMT-05:00 Maria Antonieta Ramirez < marami...@ulsaneza.edu.mx>: > Buena tarde > > > por medio del presente agradezco su tiempo y su atencion, tengo dudas > acerca de mi archivo de configuracion, mi servidor es windows server > enterprice service pack 1 y tiene 6GB de ram. > > > la aplicacion que se conecta a el tiene problea y llena la memoria virtual > de su servidor de aplicaciones, en la tabla de bloqueos me muestra unas > consultas que quedan en "idle in transaction" > > > revisando mi configuracion.. > > tengo lo siguiente en los siguientes parametros quisiera orientacion > acerca de que si la configuracion de estos parametros es correcta en > proporcion a mi servidor que es de 6GB DE RAM. ojala puedan apoyarme. > gracias!! > > > nota: mi base de datos contiene informacion que se consulta en linea para > fin educativo en maestrias y cursos. > > mi base pesa 313MB > > > Sin mas por el momento quedo en espera de sus comentarios y muchas gracias > por su apoyo!! > > > > > #----------------------------------------------------------- > ------------------- > # FILE LOCATIONS > #----------------------------------------------------------- > ------------------- > > # The default values of these variables are driven from the -D command-line > # option or PGDATA environment variable, represented here as ConfigDir. > > #data_directory = 'ConfigDir' # use data in another directory > # (change requires restart) > #hba_file = 'ConfigDir/pg_hba.conf' # host-based authentication file > # (change requires restart) > #ident_file = 'ConfigDir/pg_ident.conf' # ident configuration file > # (change requires restart) > > # If external_pid_file is not explicitly set, no extra PID file is written. > #external_pid_file = '' # write an extra PID file > # (change requires restart) > > > #----------------------------------------------------------- > ------------------- > # CONNECTIONS AND AUTHENTICATION > #----------------------------------------------------------- > ------------------- > > # - Connection Settings - > > listen_addresses = '*' # what IP address(es) to listen on;
