Configuring the logging mechanism on OpenVMS

Where can I find documetation on how to configure the logging mechanisn of ADABAS on OpenVMS… I need information about the different configurations of online/archived PLOG files and how to set each configuration.


Hi Adabas user,

you can find some information in the default documentation about Utilities esp. about adanuc.

I hope this will help you.


Hi, on OpenVMS you can switch Protection logging on/off globally by editing SAG$ROOT:[ADABAS.DBnnn]ADAUNUC.COM by setting ADANUC PLOG (for on) or ADANUC NOPLOG (to switch off). You can also enable plog journaling on a file basis using ADADBM DB=dbid,[NO]PLOG,FILE=n and view the settings using ADAREP DB=dbid,FILE=n.

As VMS has file versions, each time a new PLOG file is opened the file version is incremented by one (32767 version limit). It’s up to you to archive etc. the old PLOG files.

Hope this helps
Kind Regards
