Panorama: User is enabled to add personal SQL to dragnet list

In menu ‘Spec. additions’ / ‘Dragnet investigation’ now you have the opportunity to add your own personal SQL-statements to the predefined list of dragnet SQLs.

This SQLs are stored at Panorama’s server instance and are available for your personal browser instance only.

Choose ‘Add personal selection’ from menu ‘≡’ and customize the JSON template for your purpose.

You will get a new menu ‘Personal extensions’ in your list of SQLs then.






If you want to persist this SQLs and provide them to all users of your Panorama instance, you can store them as JSON-array in a file ‘predefined_dragnet_selections.json’ stored at PANORAMA_VAR_HOME.
The content of file ‘predefined_dragnet_selections.json’ is shown in list of dragnet SQLs if it exists in   PANORAMA_VAR_HOME directory.

Click here to show all opportunities for your personal or global extensions to dragnet list.

Common pitfalls using SQL*Net via Firewalls

It's very common that firewalls are terminating idle TCP sessions after a limited time, often after approximately one hour. Possible problem If you have a long running SQL or PL/SQL program and the firewall terminates your apparently idle TCP session this may lead to the following scenario: the database is not able to send result to client. After reaching the TCP-timeout the database server terminates the DB-Session the client program stays in socket read forever waiting for the database response Oracle's full solution: SQLNET.EXPIRE_TIME=x in sqlnet.ora Oracle's solution for this problem is setting parameter SQLNET.EXPIRE_TIME=x in sqlnet.ora where x are the minutes between keep alive packets on idle sessions that inform the firewall that this session is always alive. SQLNET.EXPIRE_TIME hast to be set in the sqlnet.ora of your RDBMS' ORACLE_HOME. Normally $ORACLE_HOME/network/admin. If you have a grid infrastructure setting SQLNET.EXPIRE_TIME in sqlnet

Oracle-DB: How to check for appropriate sequence caching

Image
A common pitfall while using sequences in Oracle-DB is forgetting to define sequence caching. The default for sequences is cache size = 0. That means, every sequence.nextval operation triggers a single write operation on dictionary table sys.SEQ$. Especially if frequently calling sequence.nextval uncached sequences may cause significant performance degradation. Frequently calling sequence.nextval in parallel sessions may lead to ramdom lock scenarios in library cache. Setting a cache size for a sequence may heavy increase performance of nextval-operations. There's a minimal memory overhead for caching a sequence because all that's needed is a counter to increase in SGA memory and a upper limit. If this limit is reached with the counter, the upper limit is increased by cache size and the new upper limit is written down once to SEQ$. The possible drawback for sequence caching is that you loose all your values between the current value and the highest cached value if yo

Oracle DB: Evaluate database audit trail with Panorama

Image
The performance analysis tool Panorama for Oracle now supports both evaluation of standard audit trail as well as evaluation of unified audit trail. The menu item "DBA General" / "Audit Trail" / "Auditing rules" shows the current configuration of the DB audit trail as well as several auditing rules for standard, fine grained and unified audit trail. With menu item "DBA General" / "Audit Trail" / "Standard audit trail" you open a dialog for evaluation of standard audit trail including find grained audit trail. Depending on the choosen value for "Grouping" single audit records are show for the selected period or the result is grouped by time with record counts for the top x OS and DB users, machines and actions. By clicking at the links in the columns for "Action", "Machine", "User" etc. you can refine the grouped result. Clicking at the column "Audits total" shows the s
