PRVT_ILM

The PRVT_ILM API is an internal API of the ILM feature and cannot be directly called by users. Only the API names are listed and the API prototypes are not described.

API	Description
be_active_ado_window	The maintenance window updates the ilmadowindow triggering time and action.
be_create_ado_window_for_each_db	The maintenance window creates ilmadowindow in each database of the instance.
be_execute_ilm	The ilmadowind performs automatic evaluation.
be_execute_ilm_dn	Automatic evaluation is performed on distributed DNs. This operation affects the overall ILM background scheduling of the cluster.
flush_task_executestate	The automatic scheduled job updates the task status.
generate_taskoid	CN generates a task ID for this scheduling.
evaluate_obj_policy	Data objects are evaluated after scheduling is triggered.
change_be_ilm	dbe_ilm_admin.enable_ilm() and disable_ilm() help functions. This operation affects the overall ILM background scheduling of the cluster.
get_compression_ratio	dbe_compression.get_compression_ratio() help function.
get_compression_type	dbe_compression.get_compression_type() help function.
get_lastmodified_time	dbe_heat_map.row_heat_map() help function.
ilm_job_action	Compression task executor, which is used for distributed DNs.
delete_expired_ilm_log	Expired logs are cleared in distributed mode.
delete_gs_ilm_task	System catalog related to the operation feature, which is used for distributed DNs.
insert_gs_ilm_jobdetail	System catalog related to the operation feature, which is used for distributed DNs.
insert_gs_ilm_task	System catalog related to the operation feature, which is used for distributed DNs.
insert_gs_ilm_taskdetail	System catalog related to the operation feature, which is used for distributed DNs.
update_gs_ilm_jobdetail	System catalog related to the operation feature, which is used for distributed DNs.
update_gs_ilm_object	System catalog related to the operation feature, which is used for distributed DNs.
update_gs_ilm_param	System catalog related to the operation feature, which is used for distributed DNs. This operation affects the overall ILM background scheduling of the cluster.
update_gs_ilm_task	System catalog related to the operation feature, which is used for distributed DNs.
gs_ilm_ticker	The maintenance window performs an action, performs a dotting operation, and records the mapping between the LSN and time.
compress_blocks	prvt_ilm.ilm_job_action() help function.
compress_block_single	Do not use this API because it is discarded.
get_job_status	dbe_ilm.stop_ilm help function.
insert_gs_ilm_param	System catalogs related to the operation feature.
query_unfinishedjob_num	Queries whether there are jobs that are not complete, including jobs in the initial and running states.
update_gs_ilm_object_flag2	System catalog related to the operation feature, which is used for distributed DNs.
ilm_seq_nextval	Obtains the next sequence value of the ILM.
ilm_seq_setval	Sets the current sequence value of the ILM.
check_compatibility	Specifies a function used to determine a database compatibility mode in a unified manner.
set_pg_settings	Specifies a function used to set the GUC parameters for setting a database compatibility mode.
check_seq	Ensures that the current value of gsilmtask_seq is greater than the maximum value of taskoid in the gs_ilm_task catalog. This parameter is used on distributed CNs.
