Cannot start instance(MaxDB) during installing Netweaver 7.5

[former_member367733]

Hi experts,

I met a problem "cannot start instance" during installing NetWeaver 7.5 on Redhat7.3. Could you please help check why this happen?

OS info:

[root@mo-36ffb5ac4 sapdata]# cat /etc/*release

NAME="Red Hat Enterprise Linux Server"

VERSION="7.3 (Maipo)"

My installation log:

And I tried to start the instance manually. This is the following logs:

[root@mo-36ffb5ac4 bin]# ./dbmcli -d LDB -u sqdldb,pxE8FZt24001 db_online

Error! Connection failed to node (local) for database LDB: -24950,ERR_USRFAIL: User authorization failed

My system SID is LDS and DB's sid is LDB.

Many thanks.

If the DB is the issue dev_disp wont help it does not show database connection issues... can you post dev_w0?

Hi Juan,

Thank you very much for your answer. Bartosz has already helped me find out why the instance cannot be started. I missed one OS configuration step(modify the /etc/hosts file) before Netweaver installed. After I modified the file as the Notes 2002167, I met another problem.

Do you have clue to resolve this problem?

Thank you very much.

Yes, the clue is on the text above...

Go to your host file (/etc/hosts) and add the entries required..

127.0.0.1 localhost

<ip of your host> <hostname>

this are basic requirements when setting up a system... read the installation guide.

Hi Juan,

I did this as the solution in the error message. But the error still popped up. I don't know how to fix it.

Many thanks.

change your entry for the reverse lookup to point to your host

127.0.0.1 mo-36ffb5ac4
