Dropping many tables at a time using pl/sql script

Hello all,

Here i'm going to give you the script to drop more number of  tables at one go. The below script is being used in our environment to drop more number of tables at the same time whenever we receive a mail from our client. This may help you also if you are in a situation. It's a best option to save time instead of dropping tables one by one. Tomorrow also we will have an activity to drop 111 tables which occupied 105 GB of space & reclaiming physical disk space activity followed by table drop.

Export and import multiple schema using expdp/impdp (Data Pump utility)

Use the below sql query to export and import multiple schema: expdp schemas=schema1,schema2,schema3 directory=DATA_PUMP_DIR dumpfile=schemas120514bkp.dmp exclude=statistics logfile=expdpschemas120514.log impdp schemas=schema1,schema2,schema3 directory=DATA_PUMP_DIR dumpfile=schemas120514bkp.dmp logfile=impdpschemas120514.log sql query to export and import a schema: expdp schemas=schema directory=DATA_PUMP_DIR dumpfile=schema120514bkp.dmp exclude=statistics logfile=expdpschema120514.log impdp schemas=schema directory=DATA_PUMP_DIR dumpfile=schema120514bkp.dmp logfile=expdpschema120514.log Parameter STATISTICS=NONE can either be used in export or import. No need to use the parameter in both. To export meta data only to get ddl of the schemas: expdp schemas=schema1,schema2,schema3 directory=TEST_DIR dumpfile=content.dat content=METADATA_ONLY exclude=statistics To get the DDL in a text file: impdp directory=TEST_DIR sqlfile=sql.dat logfile=sql.log dumpfile=content12051

Pinning execution plan for a sql_id using 'SQL Profile' to consistently reproduce a good plan

Deal all, Below post content is not my own. It is taken from MOSC document but the example shown below is taken from our environment. I got to know the below topic when we had experienced the bad SQL query performance in one of our production environment during daily batch running time. Hence we had implemented the same mentioned in the title "Pinning execution plan for a sql_id using 'SQL Profile' to consistently reproduce a good plan". Introduction The "cost-based optimizer (CBO or just optimizer) is the part of database software that determines the most efficient means of accessing the specified data (or at least what it "calculates" as the most efficient). The optimizer determines which execution plan is most efficient by considering several sources of information, including query conditions, available access paths, statistics gathered for the system, and hints. Some changes in those conditions may affect the calculations of the plan

SQL query to find the cause or reason for more archive log generation

Finding reason or cause for heavy or more archive log generation in a particular time period As i said in the previous post we are going to see SQL queries to find the cause or reason for more archive log generation in a problematic window... Sometimes customer would ask the sql query which generated more archive logs sometimes before or days before (not for current archive logs generation which is described in the previous post). In such scenarios, follow the steps below. Step 1: ====== First you must know the timing when more number of archive logs generated in the databases. for that you can use the below query. Below sql query gives how many number of archive logs generated for each and every hour... col day for a12 set lines 1000 set pages 999 col "00" for a3 col "01" for a3 col "02" for a3 col "03" for a3 col "04" for a3 col "05" for a3 col "06" for a3 col "07" for
