• determine the storage space for the upgrade of the APEX

  I put on my 11.2.0.3.12 level APEX APEX to APEX 4.2.4.00.08 version 3.2.1.00.12 version database.  I understand that I must perform the full upgrade, I am moving from version 3.2.x to 4.2.x.

  According to the APEX 4.2 Installation Guide for the full development environment, I have to spend in the following arguments:

  Where:

  • tablespace_apexis the name of the storage space for the user of the Oracle Application Express application.
  • tablespace_filesis the name of the storage space for the user to Oracle Application Express files.
  • tablespace_tempis the name of the temporary tablespace and tablespace group.
  • imagesis the virtual directory for the images of Oracle Application Express. To support future upgrades Oracle Application Express, set the directory of the virtual image that /i/ .

  APEX 3.2.x installation that follows is users:

  • Oracle Application Express Application user: APEX_030200
  • Oracle Application Express user files: FLOW_FILES

  So to determine the tablespace_apex and the tablespace_files you must connect with the user sys with sysdba privilege and run the following query:

  SELECT USERNAME
       , DEFAULT_TABLESPACE
    FROM DBA_USERS
   WHERE USERNAME IN ('FLOWS_FILES','APEX_030200')
  

  Then use the APEX_030200 user as tablespace_apex tablespace and a tablespace of the FLOW_FILES user as tablespace_files.

  I hope this helps!

• Storage spaces for different size tables

  Hello
  
  I have a situation that everyone has probably, so I would go into more detail about this.
  Working with databases with different objectives, a single OLTP and OLAP one another, the two tables with different sizes... some with 1 M, some with 100 M and others with 150 G or more.
  
  Recommendation of the Oracle, so the suite all storage spaces are created in the form of LMT, but I don't know if I can put something else to optimize performance, such as reading or writing, once the databases have different objectives and therefore with different behaviors.
  
  If someone could help me how I should give attention, I really appreciate.
  The version of database can be regarded as 10g and 11g.
  
  Thank you.

  No, really no need to worry about direct allocation tablespace in realtion to the performance of the queries. There are some operations such as the allocation of file extensions and tablespace performance impact scope object, but it can be difficult to see this. Just make sure your expandable size of file on the data files extension is large enough so that the next object needing another measure will also not wait as the file expand. With the maximum of a measure in a size auto-allouer tablespace is 64 M, a volume of measure G 1 file would be 16 degrees of object so 15 additional objects may expand (at this size) before a another file extension becomes necessary.

  What to do is determine if you want to count automatic sur-affectation to manage measurement of object allocations or to use uniform extensions so that each measure in the tablespace is the same size. If you use uniform extensions then you must make a choice of the same size for all or separate objects in small object and object of large size tablespaces and use a different scale for each size. Maybe 512K for small and 8 M wide. It's just a matter of how you want to manage your tablespace usage and growth.

• Many storage spaces and data for each quarter of the year files

  Hello

  I am junior DBA and I have a question about tablespace partitioning or data file sharing.

  I have a database of 10g in many storage spaces, for example:

  KER_DATA_2009_Q1

  KER_DATA_2009_Q2

  KER_DATA_2009_Q3

  KER_DATA_2009_Q4

  KER_INDX_2009_Q1

  KER_INDX_2009_Q2

  KER_INDX_2009_Q3

  KER_INDX_2009_Q4

  There is also a data file for each tablespace that is mentioned.

  But for this year 2013, only two big storage space I can get one and data KER_DATA, KER_INDX files.

  All tables and indexes in the whole database are KER_DATA, KER_INDX, tablespaces.

  I don't know any cut in two storage spaces and means of data files. Is this something like tablespace partitioning? This can be done automatically or someone needed to do it manually on the end of each quarter?

  This should be done to improve performance, several small files data instead a large?

  Can some admin explain this to me?

  The reason for this separation of database/tablespace was partitioning. There are a lot of tables partitioned by date column, and there are partitions for each quarter of the year. There are tablespace with a data file for each quarter (partition).

• by specifying the index tablespace in to disable the primary key constraint

  Hello
  during the ETL I want to disable constraints PK/UK to speed up the load;
  on activation of the constraint, the corresponding indices are created in a different tablespace while they were initially on the creation of the table itself
  I tried to disable PK / UK with the option 'keep the index', the index value corresponding to the status of "unusable" and use ' alter session set skip_unusable_indexes = true', but then I can't insert rows with the error.

  Error: ORA-01502: index 'xxx' or partition of such index is in unusable state

  can anyone tell if there is a way to allow the PK/UK constraint and specify the storage space for the corresponding indices, or keep the index and inserts works?
  I'd like to avoid to drop constraints / indexes and re-create them both from scratch after the load
  Thank you for the advice

  Creating an Index associated with a constraint

  Oracle database applies a UNIQUE key or a constraint integrity PRIMARY KEY on a table by creating a unique index on the unique key or primary key. This index is created automatically by the database when the constraint is enabled. No action is required by you when you run the CREATE TABLE or ALTER TABLE statement to create the index, but you can optionally specify an ESCALATION using clause to exercise control over his creation. This includes them when a constraint is defined and enabled, and when a constraint defined but disabled is selected.

• Is it possible to use GPFS or another build is a SAN storage shared for multiple ESX and ESXi hosts?

  We have a license GPFS and SAN storage. I am trying to create a storage shared for multiple ESX and ESXi hosts share existing virtual machines. We tried once NFS, it of a little slow and consume too much bandwidth LAN.

  Anyone can help answer? Thank you very much in advance!

  It depends on your storage space.

  You must connect all hosts to the same San, then follow the configuration guide of ESXi and specific documentation for your storage space (for sharing LUNS on multiple hosts).

• DataPump to a single index tablespace sqlfile gives ORA-31655

  Hi, try to use the tablespaces of data pump export functions to create a sqlfile of DDL to create indexes for a table index. When I run this command:
  
  System expdp tablespaces dumpfile = directory = DATA_PUMP_DIR idx_ts = idx_ts.dmp
  
  I get the following error:
  
  ORA-31655: no data or metadata of objects selected for employment
  
  My "Workaround" (which is not all that good) was therefore proceed as follows:
  
  the schemaname = expdp system schemas include = index directory = DATA_PUMP_DIR dumpfile = test.dmp
  
  and then do:
  
  Directory = DATA_PUMP_DIR dumpfile = test.dmp sqlfile = Impdp system indexes .sql
  
  which gives a nice script to create ALL the indexes belonging to schemaname. But what is sought is to simply create a script for the IDX_TX tablespace sqlfile.
  
  The questions are:
  
  1. is there some other expdp command-line syntax that successfully exports the DDL for this index tablespace only in a dump file?
  2 is there a way (other than a script - I have those) use of data pump succcessfully 'export' an index tablespace only?
  3. Why is this command faililng?

• Creation of names of users and storage space began with the numbers or _ $#.

  After watching a few google links, I want to sum-up rule for the design of Tablespace:

  1. always create tablespace locally managed (management of the measure).

  2. never create tablespace with hundreds of small data files to avoid a slower recovery.

  3. the types of segments that are used in the same way must be stored together.

  4. the system must be designed for the most common usage.

  5. the regions should be exceptions.

  6 feud among storage space should be kept to a minimum.

  7. the data dictionary must be isolated.

  8. always give a name to the tablespace; so it may be easy to know what contains this tablespace.

  9 http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Recommendations_to_minimize_disk_I/O_contention&anchor=iooracle

  10. never use quotation marks double tablespace name.

  11 create the tablespaces explicitly using CREATE TABLESPACE rather than implicitly by creating a table without specifying a tablespace name.

  12. create an a tablespace less as temporary for user types.

  13 specify the suffix ".dbf" for names of applications datafile, '.log' for log data file names.

  14. set the default storage parameters to take into account the size of the typical object.

  15 specify PCTINCREASE 0. Exceptions can only be made with the approval of the Central s/n.

  16 AUTOEXTEND must be enabled.

  17 MAXSIZE must be set.

  After posting the links to doc, I want to sum-up rule for the creation of the user:

  1. always follow "Requirements Minimum for passwords"
  http://docs.Oracle.com/CD/B28359_01/network.111/B28531/authentication.htm#CHDFDHAJ

  2. never use double quotes with username and passwords.

  3 assign a default Tablespace for the user.

  4 assign a Tablespace Quota for the user.

  5 avoid giving the ability for users to create objects in a table space, because the schema is the logical database for the user.

  6 enable auditing for many reasons.

  7 assign a temporary Tablespace for the user.

  8 identify the appropriate profile and role to the user.

  9. only letters, numbers and the underscore character are allowed in names. Although Oracle allows for $ and the #, they are not needed and may cause unexpected problems.

  10. all names are uppercase. Or at least unimportant in which case. Ignoring this rule usually leads to making reference to the tables and the columns very clumsy because all names must be in double quotes.

  11. the first character of the name must be a letter.

  12. keep meaningful names, but at the same time, do not use long_names_describing_every_single_detail_of_particular_object.

• How do I know the partition that is moved within the storage space?

  I'm currently moving the partitions of a table to reclaim space and I do not transfer to another tablespace, in other words, I just move into the storage space.

  The tablespace contains one table.

  The most difficult part of putting them in the same tablespace is now, that I could not easily identify which partition to date is moved. When I created the script to move partitions, I've sorted them all first.

  I asked the DBA_SEGMENTS and learned the segment_type is TEMPORARY and that the size continues to change right away.

  The nom_segment is "37.75756073" and does not say clearly what partition is moved.

  I know that the '37' part. It's a the file_id. But what is this "75756073"? I checked the object_id and data_object_id from DBA_OBJECTS, but he did not show everything.

  I questioned the block_id from DBA_EXTENTS, but neither did - it show the nom_partition.

  Any other ideas?

  Watch LAST_DDL_TIME to the USER_OBJECTS partition (the name of the table would be OBJECT_NAME and the name of the partition would be SUBOBJECT_NAME "PARTITION TABLE" would be the OBJECT_TYPE) to identify the last partition that has been moved.  Given that your script is the partition names ordered, you would know the next parttiion after it - such next partition would be one that is currently "moved".

  Hello

  The expdp command you listed in your first post may not work. You have exclude and include in the same order.

  Exclude said excluding these items but includes everything.

  Include says include only these objects and exclude everything else.

  If you use the command expdp of your second post, there is no tablespace objects in a schema export. Include = tablespace will only recreate the tablespaces and not objects in storage. If you want to do this, you must delete the schema = MDLOG and add the full = Y. Tablespace definitions are included in a full export.

  What is your ultimate goal? You want just the definitions of tablespace moved? If so

  complete expdp = include = tablespace directory =...

  If you want all the storage space and the objects in these storage spaces, so I think it would be 2 steps:

  complete expdp = include = tablespace directory...
  expdp tablespaces = tbs1, tbs2,... happy = metadata_only...

  You have not need of content = data_only, but you had it on two orders expdp so I guess that's what you wanted, so I added it.

  If you have a different purpose, then publish it and I'll see what I can find.

  Dean

  p.s. If you want to see what items are included in a particular mode you can query sys.datapump_paths. Het_type is the mode

  Full = look het_type DATABASE_EXPORT
  schemas =... Watch het_type SCHEMA_EXPORT
