Setting asm_diskstring parameter helps creating a successful ASM diskgroup.

When tried to create diskgroup FRA, and got errors as below:

Is MGMTDB Patched While Applying GI PSU/RU/RUR ?

MGMTDB will be patched as well at the same time when GI is upgraded or patched ( PSU, RU/RUR, etc).

Yes, while applying PSU patch onto GI, we can see GIMR database “-MGMTDB” is patched as well. It can be confirmed from logs.

a) Logs from “opatchauto apply” shows MGMTDB is patched while applying GI PSU:

Is MGMTDB Using HugePages ?

GIMR database “-MGMTDB” uses HugePages if Linux server is configured with HugePages.

The HugePages was configured for newly built Linix servers, and we did not change any configurations of GIMR database “-MGMTDB”. Just found MGMTDB is using HugePages automatically if HugePages is configured according to the alert log.

Interface (‘VirtualBox Host-Only Ethernet Adapter’) is not a Host-Only Adapter interface (VERR_INTERNAL_ERROR).

Refresh MAC address and get a new random MAC address helps this Host-Only Adapter interface issue.

The laptop was upgraded from Windows 8 to Windows 10 . After that ,VirtualBox 5.0 software failed to start up and there was no response at all. The software is neither up nor with any error messages.

Then uninstalled VirtualBox 5.0 and installed latest VirtualBox 5.1.6. It was better this time. But when I tried to start up one Linux virtual server, got this message:

capture_1

Checked a couple of items, all look fine:

b) Go to File->Preference->Network->Host-only Network Details, looks good.

c) “VirtualBox NDIS6 Briged Networking Driver” is checked:

d)  Click refresh button to get a new “MAC ADDRESS”.
