How to find the server is whether standby (slave) or primary(master) in Postgresql replication ?

-
Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)

How to Configuration UDEV SCSI Rules In Oracle Linux 5, 6 and 7

-
For Oracle Automatic Storage Manager (ASM) to use disks, it needs to be able to identify the devices consistently and for them to have the correct ownership and permissions. In Linux you can use ASMLib to manage these tasks, but it is seen as an additional layer of complexity and has never really gained any popularity. Instead, many people use the Linux device manager "udev" to perform these tasks. This article presents a brief overview of setting up udev rules with respect to disks for use with ASM in Oracle 11g. The examples are all done using Oracle Linux 5, 6 and 7, so they will be consistent with RHEL and CentOS 5, 6 and 7. Background Essentially, what udev does is apply rules defined in files in the "/etc/udev/rules.d" directory to the device nodes listed in the "/dev" directory. The rules can be defined in a variety of ways, but what we need to do is identify the device and say what we want udev to do with it. In this case I know all my disk

Linux ctime,mtime,atime,cmin,amin,mmin

Unix and therefore Linux uses (at least) 3 different timestamps on modern file systems (see File systems Table for info) in order to date any files. You can use these information to search for files, check logs, manage your backup and more… that’s why it is a must  for any sysadmin to clearly understand this mechanism. This page is aimed at exposing basics knowledge to understand and use files timestamps. 1) Definitions Here are some time stamps related definitions. 1.1 atime This is the Access time : atime is updated whenever file’s data is accessed (a read, write or any other access); this could be done by a system process, interactively by CLI or by a script. 1.2 mtime This is the Modification time : mtime is updated whenever the file’s content changes. This time stamp is not updated by a change of files permissions (e.g : through a chown command). It is usually used for tracking the file content changes (see the Linux time related tools section below for more inf
