IBM Db2

Pre-requisites​

Check the supported versions​

DBmarlin supports versions of IBM Db2 from 10.5 and above. Please check the list of supported platforms before continuing and contact us if you are not sure.

Create a monitoring user with the correct permissions​

Before adding a target Db2 instance in the UI you should first create a dbmarlin user in the target database instance and granting the following permissions (you can choose to use a name other than dbmarlin if you prefer).

grant execute on function SYSPROC.mon_get_connection TO USER dbmarlin;
grant execute on function SYSPROC.mon_get_activity TO USER dbmarlin;
grant execute on function SYSPROC.mon_get_database TO USER dbmarlin;
grant execute on function SYSPROC.mon_get_pkg_cache_stmt TO USER dbmarlin;
grant execute on function SYSPROC.dbm_get_cfg TO USER dbmarlin;
grant execute on specific function SYSPROC.db_get_cfg TO USER dbmarlin; 


grant select on sysibm.sysdummy1 TO USER dbmarlin;
grant select on sysibmadm.dbmcfg TO USER dbmarlin;
grant select on syscat.schemata TO USER dbmarlin;
grant select on syscat.tables TO USER dbmarlin;
grant select on syscat.indexes TO USER dbmarlin;

Adding the Database Target​

This is done through the User Interface using the Add Database screen

Executions plans​

To generate an execution plan in Db2, the monitoring user must have access to the explain_* tables.

CALL SYSPROC.SYSINSTALLOBJECTS('EXPLAIN', 'C', CAST (NULL AS VARCHAR(128)), CURRENT_USER)

Db2 in IBM Cloud​

We have certified that DBmarlin works with IBM Cloud Db2 which is the cloud hosted DBaaS (database-as-a-service) from IBM. Setting up a sensor is just like any other, except for one SSL parameter :sslConnection=true; which you can add to the Connection string under Advanced mode.
