Storage partitioning - query on multiple partitions performance?

• LUN and storage Partitions

  When you use the IBM DS4700 SAN and if ESX supports only one active path to a logic unit at a time number - if I have a logic of Production and an another LUN of Test unit number, I'd rather create a partion of storage for each, then ask SAN CTRL A - & gt; path preferred on Production LUN SAN CTRL B - & gt; the path preferred to LUN of Test? the attached picture shows how I have two paths each HBA, FC switch and SAN. I would like to optimize traffice as much as possible. Any suggestions?

  Thank you

  Am I right assuming that I would be better for the performance of each logic unit on a separte storage partition number and each controller

  Altogether.

  For each RAID Group (or group of physical disks), only 1 LUN.

  At least 2 LUNS.

  If possible (if you have 4 way and many records) also consider using 4 LUNs.

  Rember that each logic unit number must be<>

• Storage VMFS Partition Performance

  I am trying to determine if I'll get best performance of 6-300 Gb 15 K FC disks in a table 6 FC - 300 GB 15 K in a table of RAID5 or RAID10?

  I don't have much time to really sit and Experiment (would like to but time = $$).

  This is the table that will store between 5-9 WIN2k3 VM.

  I like the idea of RAID 10, which allows more than 1 drive fail (as long as it isn't the same mirror) and still survive with times of rapid reconstruction.

  This question has been turned off before, but not with the amount of readers, I want to say

  Any help is appreciated!

  If you have a load of joint task force (most do) then RAID10 will give good performance than RAID5. RAID5 has faster sequential readings as RAID10, but RAID10 is normally the one who gives you the best performance in a VMware environment where multiple virtual machines are access to the same storage.

• Mark partition performance.

  Hi gurus of the Oracle,.
  
  I had a quick question. I thought that of the 2 techniques will give me better performance.
  
  (1) a table querying and using partition name in the clause as from
  
  Select count (*) in the table table_name partition (nom_partition).
  
  The partition in the business_date for this table.
  
  (2) a table querying partitioned with a where condition clause (here the column in the where condition is partitioned for the date).
  
  "SELECT count (*) from table_name, including table_name.business_date ='1-Dec-2009.
  
  Please let me know if you need any clarification.

  Well, theoretically by using the name of the partition will be a few milliseconds faster - second method call mechanism of size of static partition of the optimizer while the first directly say which partition to use.

  You think you're going to lines updates 85K, Oracle think it will update a line.

  At the time where the existence of the first test runs that oracle think already up to 49 lines, which is probably why he uses the loop join nested for the second test. (In your version of Oracle, the subquery introduced existence a very bad assumption (small) on the amount of data will survive).

  It is possible that you will get better performance if you hint Oracle using a hash join for testing the existence - and you might want to think what test will eliminate most of the data and that we can first force.

  Having said that, however, note that MMR_DTL research is a considerable fraction of the cost of the query - and an analysis is an easy thing for Oracle cost properly - if, despite your comments on update a column with a clue to this topic, you will find that the query can be more effective if you use an index. This is more likely to be the case if data ' WHERE CAPITN_PRCS_IND = 5 AND HSPC_IND = 'Y' "is well grouped (perhaps the latest data added to the table).". "  You could then reduce the cost of maintaining this index by creating an index based on a feature that indexes only the lines where the predicate are both true so that the 2 update deletes the index entries and allows the index remain as thin as possible.

• Storage control IO to multiple LUNS on 1 table

  Yesterday I read on I/o control of storage in vSphere, and it seems logical to me. However, what has not been clarified is if/how it works when you multiple LUNS on the same table, and how you set it up in such a scenario.

  In our environment, we have 2 bays EqualLogic (PS100 and PS6000), with the array created as a single group with a little less of 7 TB of space in RAID 10.

  Most of our data is shared between 3 LUNs, 1 store our VDIs, the 2 other storage server VM, set up a single data store with a certain extent. (I'm trying to develop a plan to better distribute our virtual machines for a server) to get rid of the measure and 2) recover unused space (the server of virtual machines are only about 3 TB in size, but because of servers added and retired, takes more space on the San of 3.9 to).

  Thank you

  Each data store gets its own statistics IGCS, so each of them is controlled indepedently.

• Can't understand why this query returns multiple lines with the same data

  Hi all
  I am a relative novice and self-taught when it comes to SQL. I wrote a query to our reporting tool that returns multiple rows, and I can't understand why. I know that I can use the SELECT DISTINCT option, but it really slows the execution when I do. I'd really rather understand if I can change the code to avoid the multiples. This is the query. I've included a few statements in italics to help explain the break. Any ideas?
  
  SELECT MATSITE, MATPONUM, FIRSTRECPTDATE
  Of
  Subquery that concludes the first date on which purchase orders have been implemented with ACK State
  (SELECT ACKSTAT. PONUM AS 'ACKPONUM', (MIN (ACKSTAT. CHANGEDATE)) AS 'FIRSTACKDATE '.
  OF PZMAX. POSTATUS ACKSTAT
  WHERE (ACKSTAT. STATE = 'ACK') AND (ACKSTAT.ORGID ='CGSALTUS)
  GROUP OF ACKSTAT. PONUM),
  Subquery that concludes the first reception against a purchase order transaction for purposes of comparison
  (SELECT TRANS. PONUM AS "MATPONUM", TRANS. SITEID AS 'MATSITE', (MIN (TRANS. TRANSDATE)) AS 'FIRSTRECPTDATE '.
  OF PZMAX. MATRECTRANS TRANS
  WHERE (TRANS.ORGID ='CGSALTUS) AND (TRANS. HOUR > =: startDate and TRANS. TRANSDATE < =: endDate)
  TRANS GROUP. SITEID, TRANS. PONUM)
  WHERE
  (ACKPONUM = MATPONUM AND FIRSTRECPTDATE < FIRSTACKDATE) OR (NOT EXISTS (SELECT 1 FROM PZMAX. POSTATUS ACKSTAT2 WHERE (ACKSTAT2. PONUM = MATPONUM) AND (ACKSTAT2. STATE = 'ACK') AND (ACKSTAT2.ORGID ='CGSALTUS)))
  
  The where the instruction is intended to find when one of two conditions exists. ((1) received happened before the command either in ACK or 2) a reception that's happened, but the purchase order is never in ACK State. It seems that this second condition that creates multiple lines.
  
  Any thoughts will be appreciated geratly.

• What query is good in Performance?

  Hi all
  
  I'm trying to find duplicate records, PK-based. I wrote 2 queries. Can someone tell me what is the best in performance & why?
  
  Query 1
  Select the rowid, * from my_table a
  where ROWID is NOT in)
  Select max (ROWID)
  from my_table b
  where a.COL1 = b.COL1
  and a.COL2 = b.COL2
  and a.COL3 = b.COL3)
  and COL3 = to_char (to_date ('20090404', 'YYYYMMDD'), 'DD-MON-YYYY')
  
  
  Query 2
  Select * from my_table where rowid NOT IN (select MAX (ROWID) group by COL1, COL2, COL3 my_table)
  and COL3 = to_char (to_date ('20090404', 'YYYYMMDD'), 'DD-MON-YYYY');
  
  Thank you
  ACE

  Is COL3 in this example a VARCHAR2? Or a DATE?

  It is useless to take a literal string ('20090404'), that convert a date, and then convert the date to a string in a different format. If COL3 is a DATE, which I guess it is, then that COL3 to be converted to a string (using NLS_DATE_FORMAT of the session, which is subject to change), the forces preventing the use all indexes on COL3. If you take a string, convert it to a date and convert into a string so that you can compare it to something that gets converted from a date to a string. That's a lot of conversion going on, some of them implicit and therefore fragile.

  Especially if performance is a concern, you always want to compare the strings to strings, dates, dates. Comparison of strings to dates is fragile at best.

• ISE Server - query of multiple networks

  Hi guys

  We intend to deploy a Cisco ISE server to handle NAC for 300 users (Windows, WYSE, phones Avaya and HP printers). DHCP is running on the domain controller and the ISE interface Layer 2 visibility of all of the network segment management.

  We received an additional amount for a dedicated/completely separate switch VLAN which provides unlimited Internet access. It would be connected to a third-party router connected to the Internet, allowing connections directly on the internet. Indeed, it is a completely separate network of a single VLAN and Internet access.

  Is it not possible to manage the security of the ports for that VLAN from the ISE Server? If so, the server ISE would need an additional NIC configured in the VIRTUAL Internet LAN subnet?

  Basically, I wonder if a single ISE server can be used to manage 2 totally independent networks. The Internet would not use AD authentication and access would have to grant manually on a case by case basis.

  Thank you very much

  M

  Just to clarify, ISE has NO need to be Layer2-adjacent to clients to work. Only if you use specific profiles of the probes is this useful ever. Has no use when you perform the validation of the mac addresses or 802. 1 x.

  As for your question, yes ISE can manage the addresses of mac validation by the ex. say requiring access to your 'Internet' VLAN and your internal VLANS at the same time. However, it is not made with the 'port security' switch feature, but rather by entering the mac addresses that need access to your server to ISE and using the "group" you put them in ISE, in ads a condition when the permission access to ISE.

  1. 78 + 16 = 94

  2. 102 + 16 = 118, baseline is 100, 100 = col1, col2 = 0, number more than 100 should fill col3

  3 87 19 plus 106, 87 = col1, col2 = 13 while col1 and col2 = 100 and more col3 > 100 complete with 6

  SQL > select col1 least (a 100).

• Help with sql query / a subquery to perform the COUNT

  Hello everyone,

  Co-worker colleague asked me to post a request here in hopes of getting more support.  Here's the question:

  There are 3 tables associated with this request.  A table of the application, which displays a number of application open for a particular request, an audit table that shows you all employees who worked on this application and one employee who shows you the details of the employee table.  My colleague is trying to understand what, how to see only applications that have been published by a wizard, but not a Manager.  There are a few applications that worked on both, but he won't see this request in its results.

  Here are the tables

  EMP

  ID	FULL_NAME
  1234	John Doe
  5467	Jane Doe
  2345	Clark Kent
  5432	June Cleaver

  Unfortunately, this table does not have a title column (which was created provider, so we cannot change the internal structure).  My colleague knows who is the Assistant and the Director, then in this case, the first two of the id:

  1234 and 5467 are managers and the other 2 are assistants

  T_APPLICATION

  app_id	app_number	date_opened	app_type
  9018	54778	JANUARY 10, 2014	NETWORK
  9019	54779	JANUARY 11, 2014	DATABASE
  9010	55000	MARCH 12, 2014	MATERIAL

  T_APP_AUDIT

  APP_ID	PROCESSED_BY
  9018	1234
  9018	2345
  9018	5432
  9019	2345
  9019	5432
  9010	5432

  So, here is the actual query, I was given: it is actually to check the number of times that each application has been published per person:

  Select a.app_id, c.full_name, count (*) that controls

  t_application a, t_app_audit b, c of the emp

  where a.app_id = b.app_id and b.processed_by = c.id and

  a.app_type in ('NETWORK', "DATABASE")

  and b.processed not in ('1234, ' 5467')

  GROUP OF A.APP_ID, c.full_name;

  IF I won't see 9018 in my results, since at one time it was edited by a Manager (1234).  Unfortunately, this request does not eliminate the app_id 9018, it eliminates only the name of handlers appear in the query.  I hope I've explained this properly, and any help to point us in the right direction is welcomed.  Thanks in advance.

  Select

  a.app_id

  c.full_name

  , count (*) as the controls

  of t_application one

  t_app_audit b

  c of the emp

  where a.app_id = b.app_id

  and b.processed_by = c.id

  and a.app_type in ('NETWORK', "DATABASE")

  and b.app_id by (not in

  Select app_id

  of t_app_audit

  where processed_by in ('1234, ' 5467')

  )

  GROUP OF A.APP_ID, c.full_name;
