SQWareProduction:cassandra

Presentation

Usage

It's the module locally operating of cassandra.
It is entirely written in ksh and sql.
It allows to manage the operation for cassandra.
Example uses of the tool:

Backup
Recovery
Compute statistics
Indicators collection to store in referential database SQWareRepository
Rotate logs
....

This module is deployed locally on the machine hosting the authorities to manage, in order to avoid any points of weakness related to an NFS mount or whatever. The deployment is done through a simple command SQWareCentral module using inventory located in SQWareRepository !

Explanation of directories

Directories located in $gvsqw_CasBin:

bin : Directory containing standard scripts
bin_cust : Directory containing customs scripts for your environnement
etc : Directory containing the standard files of configuration
etc_cust : Directory containing the customs files of configuration for your environnement (overload standards)
help : Directory containing the standard files of help
help_cust : Directory containing the customs files of help for your environnement
lib : Directory containing the generic shell function librairies
lib_cust : Directory containing the generic shell function librairies (overload standards)
spm : Contain sql query toolkit
tools : Directory containing the standard scripts used on an ad hoc
tools_cust : Directory containing the customs scripts used on an ad hoc for your environnement
menu : Directory containing the standard menus
menu_cust : Directory containing the custom menus for your environnement

Warning:
Do not change the standard scripts and configuration files of dbSQWare.

Use directories *_cust for customizations. This will facilitate version upgrades.

Naming convention of files

The majority of files are named with suffixes:

*.ksh : for scripts
*.cfg : for configuration files
*.lib : for function librairies
*.hlp : for help files

Warning:
Do not change the standard scripts and configuration files of dbSQWare.

Use directories *_cust for customizations. This will facilitate version upgrades.

Naming convention in scripts

In general, the following naming convention is used in all scripts of SQWareProduction:

gvsqw_ {} : global variable initialized by the environment and / or generic library
lvsqw_ {} : local variable initialized by the script and / or a specific library
gfsqw_ {} : function defined by a generic library
lfsqw_ {} : function defined by the script and / or a specific library

bin

sqwcas_CentralisedNodetool.ksh

Script $gvsqw_CasBin/bin/sqwcas_CentralisedNodetool.ksh:

Execute nodetool command on all selected nodes in parallel
You have to select le options of nodetool to execute
You can also choose:

Aggressiveness of run (number of seconds between two runs)

Scope of the execution (by default: Local)

** Local => only on the local node
** LocalNode => only on the local node

** DC_$DCName => all nodes on the datacenter '$DCName'
** All => all nodes on the cluster(all datacenters)
** AllNodes => all nodes on the cluster(all datacenters)
