-4 connection broken message when selecting complete backup in DBM GUI

[Former Member]

I am not able to backup my SDB anymore!! When I click on the Complete backup option, there is a -4 connection broken message and then a -4 wrong connection type. When I try to create a new backup media, the modified date is 12:00AM no matter when I create it. If I try to execute the backup, I receive error -24985 medium not found. I have tried clearing the entries in the SDB.knl and SDB.mdf files, but that has not resolved the issue.

Hello Doug,

-> If you are the SAP customer, I recommend you to create the OSS ticket.

=> we could logon to the system via OSS and take a look closer on this issue.

-> Please provide more information to get clear on the reported issue.

• Please don't correct manually the entries in the SDB.knl and SDB.mdf files !!

• Please update with output of the following commands:

dbmcli inst_enum

dbmcli db_enum

xinstinfo SDB

dbmcli -d SDB -u <dbm-user>,<pwd> medium_getall

dbmcli -d SDB -u <dbm-user>,<pwd> medium_delete <medium-name>

• What errors did you see in the dbmsrv-<servername>.prt located in the /sapdb/data/wrk by default installation?

• Please post the commands executed/errors entries in the dbm.prt, located in database RUNDIRECTORY.

Thank you and best regards, Natalia Khlopina

Thank you for the response. I opened an OSS note and the issue has since been resolved. The problem was that the dbm.mmm file had grown to large. Entries had to be manually deleted out of the file.
