A newly designed Replication task (with default settings) reported errors in the first run:
2023-03-15T21:02:28 [STREAM_COMPONEN ]E: Replication task cannot support lobs, since log stream staging task does not [1020480] (ar_cdc_channel.c:261)
2023-03-15T21:02:28 [METADATA_MANAGE ]E: Allocating utility stream component failed [1020480] (metadatamanager.c:837)
2023-03-15T21:02:28 [METADATA_MANAGE ]E: Cannot create the source utility component [1020480] (metadatamanager.c:753)
2023-03-15T21:02:28 [TASK_MANAGER ]E: Creating Metadata Manager's utility components failed [1020480] (replicationtask.c:3893)
In general this error comes with "Replicate LOB columns" is deselected in Log Stream Staging task :
Workaround:
- Enable "Replicate LOB columns" in Log Stream Staging task if LOB columns are needed, or see (2), (3) below.
- If no need to replicate LOB columns, or there are no LOB columns in the table(s) selected, then Edit Replication task and SAVE (any change is good enough, eg change Task setting --> Logging --> PERFORMANCE from INFO to Trace, SAVE, and change it back to INFO again). This operation will add the missing components implicitly.
- Or export/import the Replication task by adding the missing property explicitly:
"common_settings": {
"support_lobs": false,
"change_table_settings": {
