Reduce SAP BO size to the minimum - delete logging (CMS, Audit, Tomcat), core, audit and more files

Hi experts,

There can be a number of reasons why administrators would like to reduce the size of SAP BO environment even though the disk space is very cheap nowadays.

In my case, I often need a virtual PROD copy on my local PC for various consulting needs. These days, laptops equipped only with SSD does not offer hundreds of free GB storage.

Therefore I would like to open a discussion how to reduce the size of SAP BO environment to the minimum.

Currently I have accomplished those steps and managed to reduce the disk size significantly.

  1. Delete CMS BI4_CMS.log
  2. Delete Audit BI4_Audit.log

Logging location in Unix: home/user/bobi/sqlanywhere/database

For step 1 and 2 I have stopped the Tomact, all the CCM servers and SQL Anywhere DB. Once the CMS database is stopped, you can make an offline backup or truncate the transaction log file as described in the earlier replies (SAP thread 3734145).

3. Delete Tomcat logs

All the xname.log files at location in Unix: /home/user/bobi/sap_bobj/tomcat/logs

4. Delete SAP BO logging

All the xname.log files at location in Unix: /home/user/bobi/sap_bobj/logging

5. Delete Audit files

All the xname.txt files at location in Unix: /home/user/bobi/sap_bobj/data/Auditing

6. Empty the recycle bin via CMC > Recycle Bin

7. Stop Audit and Delete events Older Than 1 Day

8. Delete CMC > Monitoring Alers and Watchlists

9. optional - Delete all the Personal Folders if it is not needed (in my case not). Delete all the users and migrated them with "no dependencies" back from the original BO environment. This action deletes all the reports and retrieved data in user personal folders but keeps all the users in the test environment.

10. Delete all the backup files - if you have set up any backups of BO content, CMS or Audit DB.

This is all I have done so far to minimize the disk size.

I have found out that there are 20 GB disk size allocated to the core.#### files at the location /home/user/bobi/sap_bobj/enterprise_xi40/linux_x64.

Can I delete those core.#### files without making any harm to BO system?

I found a number of posts and it should be fine for SAP systems. But what about the SAP BO?

Threads: 3196992, 3933249. SAP Note: 16513 - File system full - what can you do?

Do you know if there is anything else that is possible to delete without harming SAP BO environment? Any other ideas how to minimize the size of SAP BO? Is it possible to delete Audit DB if it is not needed?

    For this : "I have found out that there are 20 GB disk size allocated to the core.#### files at the location /home/user/bobi/sap_bobj/enterprise_xi40/linux_x64. Can I delete those core.#### files without making any harm to BO system?"

    there is no allocation for core files, core files are generated when something crashes on *nix systems.
    So, if you have core files - that means your BOE processes are crashing for some reason.
    You can delete those core files, but you should investigate which process or processes generated them first and then investigate why that process (-es) is crashing.
