How to check HDB startup issues

#HDB info showed that not all index servers are started.

hdb info

Since this is multitenant database, looked in following directory for the error logs:

/usr/sap/<SYSTEM SID>/HDB<Instance Number>/<Host Name>/trace/DB_<TENANT SID>/.

For SAP HANA single database, trace files can be found at:

/usr/sap/<SYSTEM SID>/HDB<Instance Number>/<Host Name>/trace/

Found the issue, resolved and restarted to get all my index servers running again.

R3trans and hdbuserstore

When you change the password of connecting user of SAP HANA database, same should be updated in the key file of the HDBUSERSTORE on the Application Server.

You should be logged in with <SIDADM> for this procedure.  Take care of this specially if you application server and database are running on same server.

#> hdbuserstore SET DEFAULT <hostname>:3<instance Number>15 <user> <password>

Note: User option -i along with the command if you want to enter the options (mainly password) interactively.

Example:

hdbuserstore SET DEFAULT hanahost:30015 SYSTEM Hana@123

Once updated check the list using the below command.

#> hdbuserstore list

DATA FILE : /home/appadm/.hdb/hanahost/SSFS_HDB.DAT
KEY FILE : /home/appadm/.hdb/hanahost/SSFS_HDB.KEY

KEY DEFAULT
ENV : HANAHOST:30015
USER: SYSTEM

You can now check the connectivity with the DATABASE using R3trans -d.

If R3trans -d reports error, check the connectivity with hdbsql using the key created above.

#> hdbsql -U <KEY>      #Key is “DEFAULT” in our example.

This should connect to the database without any issues.

You might receive error sql code  rcSQL = -10709 in case of connectivity issues. Please check the host name and port again in case of issues.
