Hello Mark,
When connecting using a service, the parallel slaves will be spawned only
on the instance/instances where service is started. Parallel_force_local
will prevent parallel slaves from leaving the current instance.
I haven't tried yet hanganalyze, I just started to look into it, I was
curious if someone faced a similar issue or had any clue.
Thanks

Hello,
DB Version 12.0.1.2
I noticed a strange situation and I`m curios if someone faced a similar
situation or have any clue about the reason:
While executing a partition move:
ALTER TABLE t move PARTITION p TABLESPACE t ROW store COMPRESS advanced
lob l store AS (COMPRESS medium TABLESPACE tl)
UPDATE INDEXES PARALLEL 8;
-> one query slave remain stuck into wait "row cache lock" (p2 = 0, p3 =3)
-> the blocker is actual query coordinator who is idle all this time
Much appreciated,
Laurentiu.
