Dear fellows of the Oracle,
I recently ran into a problem when trying to execute the I/O calibration. Environment: Oracle 11.2.0.3.0, Solaris 10 (SunOS 5.10 Generic_147440-12 sun4u sparc SUNW,SPARC-Enterprise).
Here's what happened:
Error starting at line 2 in command:
DECLARE
lat INTEGER;
iops INTEGER;
mbps INTEGER;
BEGIN
--DBMS_RESOURCE_MANAGER.CALIBRATE_IO(<NUM_DISKS>, <MAX_LATENCY>,iops,
mbps, lat);
DBMS_RESOURCE_MANAGER.CALIBRATE_IO (16, 20, iops, mbps, lat); DBMS_OUTPUT.PUT_LINE ('max_iops = ' || iops); DBMS_OUTPUT.PUT_LINE ('latency = ' || lat); dbms_output.put_line('max_mbps = ' || mbps);end;
Error report:
ORA-56719: Error spawning or communicating with calibration slave ORA-06512: at "SYS.DBMS_RMIN", line 463 ORA-06512: at "SYS.DBMS_RESOURCE_MANAGER", line 1302 ORA-06512: at line 7
The few hits on MOS point to bugs or scenarios that don't apply to this
environment.
BUT: We use Oracle Disk Manager (ODM) on VxFS.
Has anyone had similar experiences? Suggestions, aside from contacting support or setting max_pmbps manually?
Cheers,
Uwe
