OL 8 and BTRFS

Dude!Jun 2 2019 — edited Jun 2 2019

Hi,

Starting with RHEL 8, Red Hat no longer includes a driver for BTRFS and that the technology has been abandoned in favor of Red Hat's stratis, which I understand is a wrapper for LVM an XFS. Beside that this does not supersede BTRFS

What effect will this have on technologies like LXC and Docker? I've found the following on the web:

Note that Red Hat Enterprise Linux (RHEL) removes the Btrfs storage driver from their build of Docker, both on the Extra Packages for Enterprise Linux (EPEL) repository and the version released for RHEL7. (https://www.thegeekdiary.com/how-to-configure-btrfs-as-the-storage-engine-in-docker/ )

I'm not sure about LXC with may also supports LVM, but I understand Docker from the OL7 optional repository relies on BTRFS.

Thanks.

try to set Disabled property for that fourth SOC, to be false _only if first three SOC attributes are set to non-null values...

OR, make 4.th SOC ;disabled property to be false only if 3.-th SOC value are set, then the same for 3. SOC (depends on 2. SOC), then the same for 2. SOC, etc... got a point?

Jose Aróstegui

Excellent idea!

Can you help me please a bit to build the expression?

I don't know how to reference the fields as they are inside a Query Panel based on a View Critera.

This 4th Lov is dependent on all 3 lovs?

If you are using view cirteria then uncheck "Ignore Null Values" Check box in criteria to not show any data in case of no value is selected in other 3 lovs

Thanks a lot for your help Ashish.

This 4th Lov is dependent on all 3 lovs?

2nd Lov depends on 1st

3rd Lov depends on 2nd

4th Lov depends on 3rd

If you are using view cirteria then uncheck "Ignore Null Values" Check box in ...

Ignore null values is not editable:

I've tried your solution Igonre null values in viewCriteria -Jdeveloper 12c (Not a bug but a change) – Ashish Awasthi's Blog (Jdev/ADF) but It didn't activate the checkbox either.

Regards,

Jose.

Hi Jose

It'll not activate checkbox , you just need to add GenerateIsNullClauseForBindVars="false" under viecriteriItem tag like this and then check

<ViewCriteriaItem

    Name="DepartmentId"

    ViewAttribute="DepartmentId"

    Operator="="

    Conjunction="AND"

    Value=":BindDeptId"

    IsBindVarValue="true"

    Required="Optional"

    **GenerateIsNullClauseForBindVars="false"**/>

After this 4th lov will not show any data untill 3rd one is selected
