OCF_HEARTBEAT_DB2(7)

NAME
ocf_heartbeat_db2 - Resource Agent that manages an IBM DB2 LUW databases in Standard role as primitive or in HADR roles as promotable configuration. Multiple partitions are supported.

SYNOPSIS

db2 [start | stop | monitor | promote | demote | meta-data | validate-all]

DESCRIPTION

Resource Agent that manages an IBM DB2 LUW databases in Standard role as primitive or in HADR roles in promotable configuration. Multiple partitions are supported.

Standard mode:

An instance including all or selected databases is made highly available. Configure each partition as a separate primitive resource.

HADR mode:

A single database in HADR configuration is made highly available by automating takeover operations. Configure a promotable resource with notifications enabled and an additional monitoring operation with role "Promoted".

In case of HADR be very deliberate in specifying intervals/timeouts. The detection of a failure including promote must complete within HADR_PEER_WINDOW.

In addition to honoring requirements for crash recovery etc. for your specific database use the following relations as guidance:

"monitor interval" < HADR_PEER_WINDOW - (appr 30 sec)

"promote timeout" < HADR_PEER_WINDOW + (appr 20 sec)

SUPPORTED PARAMETERS

instance
    The instance of the database(s).

    (unique, required, string, no default)

dblist
    List of databases to be managed, e.g "db1 db2". Defaults to all databases in the instance. Specify one db for HADR mode.

    (optional, string, no default)

skip_basic_sql_health_check
    Skip basic health check SQL query.

    Only set to "true" when the "monitor_retries" and "monitor_retry_all_errors" parameters arent enough to avoid issues under high load.

    (optional, boolean, default false)

monitor_retries
    Monitor retries before failing.

    (optional, string, default "1")

monitor_retries_sleep
    Monitor sleep between tries.

    (optional, string, default "1")

monitor_retry_all_errors
    Set to true to retry monitor-action for all errors instead of the default "db2pd" race conditions.

    (optional, string, default "false")

admin
    DEPRECATED: The admin user of the instance.

    (optional, string, no default)

dbpartitionnum
    The number of the partition (DBPARTITIONNUM) to be managed.

    (optional, string, default "0")

SUPPORTED ACTIONS

This resource agent supports the following actions (operations):

start
    Starts the resource. Suggested minimum timeout: 120s.

stop
    Stops the resource. Suggested minimum timeout: 120s.

promote
    Promotes the resource to the Master role. Suggested minimum timeout: 120s.

demote
    Demotes the resource to the Slave role. Suggested minimum timeout: 120s.

monitor
    Performs a detailed status check. Suggested minimum timeout: 60s. Suggested interval: 20s.

monitor (Promoted role)
    Performs a detailed status check. Suggested minimum timeout: 60s. Suggested interval: 22s.

validate-all
    Performs a validation of the resource configuration. Suggested minimum timeout: 5s.

meta-data
    Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

EXAMPLE CRM SHELL

The following is an example configuration for a db2 resource using the crm(8) shell:

    primitive p_db2 ocf:heartbeat:db2 \
      params \
        instance=string \
      op monitor depth="0" timeout="60s" interval="20s" \
      op monitor depth="0" timeout="60s" role="Promoted" interval="22s"

    ms ms_db2 p_db2 \
      meta notify="true" interleave="true"

EXAMPLE PCS

The following is an example configuration for a db2 resource using pcs(8)

    pcs resource create p_db2 ocf:heartbeat:db2 \
      instance=string \
      op monitor OCF_CHECK_LEVEL="0" timeout="60s" interval="20s" \
      op monitor OCF_CHECK_LEVEL="0" timeout="60s" role="Promoted" interval="22s" promotable
