two sapdb instances on the same host -> startup error

[Former Member]

Dear all,

I have two sapdb (livecache) instances on the same aix host. DL1 has version 7.6.0 and QL1 7.4.2.

I am able to start DL1, but I have an issue with QL1. QL1 wants to access the DL1 devspaces, after it has open its own datafiles.

Hi,

as you're an official SAP customer (you're using liveCache), please open an official message on queue BC-DB-LVC*.

For the analysis, please open the Telnet-connection to the system, as SAP's support will need it.

Hello Roland

finally i could figure out what the problem was. The QL1 has been built up as a copy from DL1. But I forgot to change the logvolume DB parameters. Now I changed them, and resetted the logs in admin mode:

dbmcli -u control,xxxxx -d QL1

util_execute clear log

Livecache runs again.
