RECLAIM SPACE IN /HANA/LOG IS 100% FULL.

Hi team,

Initially we face an issue for filling /hana/log mount in sap hana database.

But firstly let me know you guys that how to reclaim the space in server when your /hana/log mount point is getting full.

Step1) Initially take full complete backup from hana studio and while backup is complete take system backup also.

Step2) Open hana studio with system user database and also with your tenant database and run
“ALTER SYSTEM RECLAIM LOG”.

Step3) while running the same, you find space is get reclaimed on prod server.

In case when /hana/log is get 100%  in this case, shutdown the database immediately and then move small archive log of alteast 2 GB to run the database.

1)     Move the archive logs to another location where space is available and make linking to start the database part.
Use command ln -s to create linking and use unlink command to unlink the linking.

2)     Once space is reclaimed by step1 and step2 , again shutdown the whole database part and then move the archive log to their original location and then again start the Database.
NOTE—NEVER REMOVE ARCHIVE LOG IN HANA DATABASE BY USING LINUX COMMAND.

Query for Tablespace usage with Autoextend

-
                                         Monitoring Tablespace Usage in Oracle I often see questions in Oracle newsgroups and forums about monitoring space in tablespaces, and many of those questions are regarding Enterprise Manager 12c and the alerts it generates reporting the percentage of used space. Of course how you monitor free space depends on whether or not the datafiles are autoextensible. Let's look at several ways to monitor free and used space, starting with methods used in older releases. In versions prior to Oracle 10 DBA_TABLESPACES, DBA_DATA_FILES and DBA_FREE_SPACE were used to generate such reports. One script, from MOS, uses these three views to compute the used space percentage: SELECT SUM(s.used_gb)/SUM(f.total_gb)*100 FROM dba_tablespaces t, ( SELECT tablespace_name, SUM(NVL(bytes,0))/(1024*1024*1024) total_gb FROM dba_data_files ...

How to configure multiple Oracle listeners

-
How to configure multiple Oracle listeners It happened to me few times during the stress tests that Oracle listener became a bottleneck and not be able to handle the required workload. It was resolved by creating  multiple  listeners which appeared to be a quick solution.  Here is a short step-by-step procedure to configure multiple Oracle listeners  on Solaris for standalone Oracle 9i and 10g environment. 1)  First of all, add additional NIC and cables. They can be on separate subnetwork or the same. In the later, make sure to set static route if needed.    2) Assume that we are going to configure two listeners,   LISTENER and LISTENER2 Modify listener.ora and tnsnames.ora as following: Here is a sample of   listener.ora  LISTENER =   (DESCRIPTION_LIST =     (DESCRIPTION =       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.3)(PORT = 1521))     ) ...
