For achieving the efficient management and storage facilities, the Oracle DBA helps in organizing the multimedia data through interMedia. Wide ranges of data can include files like, video clips, images, line drawings, audio clips, etc. Here are some effective steps that help in the proper tuning process.

Set Database With Initialization Parameters: With the help of the SGA (System Global Area) and Oracle, the database tuning takes place. For availing faster access, the SGA stores various data within the memory. The SGA should be adequately large for storing the data, but it should neither be too little nor too large in nature. The improper size may degrade the performances of the SGA.

  • DB_BLOCK_SIZE: This is the parameter of the size where the database can be measured in blocks, within various bytes. The size of the blocks determines the number of rows within the Oracle data, which can be saved, within a single page of the database.
  • DB_CACHE_SIZE: The parameter measures the actual size of the buffer pool, which is by default, with the bytes. As soon as the ‘show’ statement is displayed with the SQL, the buffer value of the database is shown instantly.

Create Tables Through Column Objects: At first, you are required to initialize the column objects internally. The characteristics of the storage and the table space can be indicated with the help of the BLOB. The Remote DBA Oracle can be tuned by setting the column objects through interMedia including the Binary Large Object (BLOB).

Specify The Storage Characteristics And Table Space: When you are creating tables and defining the objects in the columns, the tablespace plays a very important role. The interMedia objects of the column can only perform in their best manner, with the help of the properly defined storagespace.

Cache or NoCache : The Cache option may contain the data of BLOB that can be frequently accessed. The data can be inserted into the database, with the help of the cache option. The LOGGING functions can easily be used with the Cache option. If the BLOB data is ready very infrequently, then you can use the NoCache option. You can also use the options of Cache Reads when the data is required, within the buffer cache and the write operations should be used frequently.

CHUNK Features: For measuring the number of bytes, within the interMedia column objects, the CHUNK option can be used. It can also help in accessing one data at a time. The CHUNK option can be arranged, within the multiple database blocks. The sizes of the blocks may be a little larger than the video, audio or image data sizes.

Therefore, you can easily transfer the multimedia data with the help of the data pump of Oracle. The best performances can only be obtained when you can easily access the interMedia objects by using the NoCache option. The updating functions of the data help you in copying the entire data and updating them through the interMedia object. All these functions help in improving the data with the retrieval processes.
