Client tool

gsql

gsql is a database connection tool provided by openGauss and runs in the command-line interface (CLI). Users can use gsql to connect to a server and perform operations and maintenance on the server. In addition to basic functions for performing operations on a database, gsql provides multiple Advanced Features for users.

Server tool

gs_check

gs_check has been enhanced to unify functions of various check tools, such as gs_check and gs_checkos. It helps users fully check openGauss runtime, OS, network, and database running environments; as well as perform comprehensive checks on various environments before major operations in openGauss, ensuring smooth operation.

gs_checkos

gs_checkos checks OS information, control parameters, and disk configurations, and configures control parameters, I/O parameters, network parameters, and THP services.

gs_checkperf

gs_checkperf routinely checks openGauss-level performance (host CPU, Gauss GPU, and I/O usage), node-level performance (CPU, memory, and I/O usage), session-/process-level performance (CPU, memory, and I/O usage), and SSD performance (read and write performance). It provides openGauss load information for users so that they can fine-tune database performance accordingly.

gs_collector

When openGauss is faulty, gs_collector collects OS information, log information, and configuration file information to locate the fault.

gs_dump

gs_dump exports database information. It can export complete, consistent data of database objects (such as databases, schemas, tables, and views) without affecting the normal access of users to the databases.

gs_dumpall

gs_dumpall exports database information. It can export complete, consistent data of openGauss database objects without affecting the normal access of users to the database.

gs_guc

gs_guc is used to set parameters in openGauss configuration files (postgresql.conf or pg_hba.conf). The default parameter values in a configuration file are consistent with those for a standalone database.

gs_om

gs_om, provided by openGauss, helps you maintain openGauss, including starting and stopping openGauss, querying the openGauss status, generating static configuration files, updating dynamic configuration files, replacing SSL certificates, starting and stopping Kerberos authentication, and showing help information and version numbers.

gs_restore

gs_restore, provided by openGauss, is used to import data that was exported using gs_dump. It can also be used to import files exported by gs_dump.

gs_ssh

gs_ssh, provided by openGauss, helps users run the same command on multiple nodes in openGauss.
