Different connection status between 2 servers
Hello All,
Actually, We have a problem in our server (RHEL 7.1), 1st server is used for payment apps like switch card payment (passthru only), and 2nd server is used for Database transaction.
When high transaction there is different connection between Apps Server and DB server, Apps Server sends connection to DB Server, but sometimes that's connection not ESTABLISHED like low traffic (I checked thru netstat in 2 servers). I have changed value Local_port range, and fin_timeout but it wasn't solve this problem, and I think my current kernel needs to update kernel to latest or stable version to solve this.
current kernel : 3.10.0-229.e17.x86_64
Please give me suggest about our this connection problem.
Thank you
Regards

lfc_starttrans
LFC_STARTTRANS(3) LFC Library Functions LFC_STARTTRANS(3)
NAME
lfc_starttrans - start transaction mode
SYNOPSIS
#include <sys/types.h>
#include "lfc_api.h"
int lfc_starttrans (char *server, char *comment);
DESCRIPTION
lfc_starttrans starts transaction mode. The connection to the Name Server is kept open until one of the DB update operation fails or
lfc_aborttrans or lfc_endtrans is explicitly called. If all the DB update operations between lfc_starttrans and lfc_endtrans are success-
ful, a COMMIT is done. If any DB update operation fails or if an explicit lfc_aborttrans is done, a ROLLBACK is done. The comment is
logged in the server log.
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
ERRORS
EINVAL The length of comment exceeds CA_MAXCOMMENTLEN.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
ENSNACT Name server is not running or is being shutdown.
