Reserved memory bis

I reserved memory in VMS 8.2 and did an autogen. I rebooted and got bugchecks. The reason why is not important.

So, I tried to boot minimal for removing the reserved memory in sysman.

To my surprise res show didn't show anything. So, I couldn't remove it.

My question : how do I remove reserved memory while booted minimal ?

(the problem is already solved so only answer on this question)

Re: Reserved memory bis

Found it.

The setup is in the file sys$system:vms$reserved_memory.data.

So my new question is : why didn't sysman find it ?

Re: Reserved memory bis

Wim,

reserved memory is initialized during system initialization (in [SYS]INIT), but only during a full boot (not when booted minimum).

The SYSMAN RESERVED_MEMORY ADD and REMOVE command are used to read/write the Reserved Memory Registry data file (SYS$SYSTEM:VMS$RESERVED_MEMORY.DATA).

The SYSMAN RESERVED_MEMORY LIST command is supposed to display the contents of the reserved memory data file. So - when booted minimum - you can use the SYSMAN RES LIST command to show the current entries in the file and RES REMOVE to remove any reservations.

Volker,

I can asure you that it wasn't shown.
When I booted normally afterwards, it was shown (I restored the old system params, undoing the autogen).

Re: Reserved memory bis

Wim,

I tested this on an OpenVMS I64 V8.2 system BEFORE writing the answer to your question.


To my surprise res show didn't show anything. So, I couldn't remove it.


Sure, RES SHOW also did not show anything during my test (booted minimum), but SYSMAN> RES LIST did show the reserved memory section and I could then remove it with SYSMAN> RES REMOVE ... - unfortunately, I did not capture the terminal session at that time - especially as everything worked as documented and expected.

Re: Reserved memory bis

Volker,

You are correct. RES SHOW didn't show anything but RES LIST should. Thx for the clarrifiocation. I read the help text in 7.3 and then LIST wasn't documented.
