Exadata :: How To Get The Serial Numbers From Switches
Mar 20, 2013
My management is wanting to know the serial numbers of all the components of our two Exadata machines: one quarter-rack V2 and one half-rack V1
I can use dmidecode to get the appropriate information for comp nodes and storage cells, but not for the Cisco/Voltaire switch, nor the IB switches. I read MOS 1299791.1 and the thought of asking a DOC operative to pull out the label ‘which could damage the switch’ worries me quite a bit.
Is it still true that we are unable to obtain the serial number for the IB switches and the Cisco/Voltaire switches from the CLI of the switches themselves? Sad face.
Data block 1- master_blk : For date/customer of sale invoice Data block 2- detail_blk1 (detail of the master block - For products and qty) Data block 3- detail_blk2 (detail of DETAIL_BLK1 For entering serial numbers of products)
My requirement is that whatever quantity user enter in data block 2 against each product he must enter equal number of serial numbers of that product in data block 3.
For this I have created on item (cnt_iteml : to count product's serial numbers in block3 ) in data block 2, and on summary item (t_serial_no ) in block3.
Whenever user changes in quantity, cnt_iteml: item is populated with t_serial_no in block3 of that product by following trigger on quantity column.
Following trigger is written on block level at data block-3 to populate cnt_iteml with t_serial_no. PRE-RECORD
IF GET_BLOCK_PROPERTY('SERIAL_NUMBERS',STATUS) IN ('CHANGED') THEN :stock_transactions.cnt_itl:=:serial_numbers.t_serial_no; END IF;
Above triggers are fulfilling my requirement except following condition.
If user after entering serial numbers in block 3 and without saving goes back to block2 and try to navigate to another record he gets a message asking him to save changes by forms. At this time if user presses no then cnt_itl item is not been populated with t_serial_no item's value.
What I want in above condition is that if user was inserting new record cnt_it item should be populated with 0, so that he shouldn't be able to save this record. And If he was updating then cnt_itl item should be populated with actual no of records in database against that product.
One of my databases which is running on exadata x2-2 , has been restored to non-exadata machine in order to test few things. I had a sub-partition table in the exadata , compressed for query high. test machine (NOT EXADATA) , after uncompressing this subpartiton tables i am getting the following err message :
ORA-64307: hybrid columnar compression is not supported for tablespaces on this storage type I have executed the following commands : alter table crm.cm_ncd modify partition P01_CM_NCD nocompress; alter table crm.cm_ncd modify partition P02_CM_NCD nocompress; alter table crm.cm_ncd modify partition P03_CM_NCD nocompress;
[code]...
ERROR at line 1: ORA-12801: error signaled in parallel query server P005 ORA-64307: hybrid columnar compression is not supported for tablespaces on this storage type If all the partitions are uncompressed why i am getting this error message ?
I am having an Oracle 11g R2 RAC setup. My database size is 22TB in normal servers. I have checked my database in Exadata X2-2 and found out that the HCC was good and as per my assumption the 22TB can come down to 10TB .
My challenge is i need to transfer the 22TB data to the exadata quater rack which is having space constraint. Is there any way other than export & Import as data export and import will use entire 22TB. Is there any way to transfer the data to Exadata with compressed form from the source server.
I am having doubt on the no_index concept in oracle. I am using oracle exadata server.It is basically data warehouse project.I am in the situation to join some tables and get the result set for reporting purpose.
Among the tables, 2 tables having huge count.1st table has more than - 1,000,000,000 rows2nd table has more than - 200,000,000 rows when i join these 2 tables with some small set of tables, it is taking long time (around 20 MIN) to retrieve the result set. The final result set is around 100 rows only.
But, when i force NO_INDEX hint in the same query, is giving the same result in very fast manner(around 5 MIN). Because it is working based on cell smart scan. So, can i force the NO_INDEX hint to all tables? I forced the NO_INDEX hint only the table which is contain 200,000,000 rows not for others.
Query Plan : Normal Query using the the range scan based on the key. No_INDEX Query going full table scan.
I have a table test with column containing dates, characters and numbers. I have to extract the number part and the three characters before the number . My data looks like :
TEST ID DATA 1 3/12/2007 2 0 3 3/8/2010 ABC 217 4 NONE 5 COLM XYZ 469 6/8/2011 6 LMN 209
1) Post Installation check list ie: How can I see every things are installed correctly. 2) upgrade the exadata OS version . 3) Upgrade the Database. 4) Test Migration from Oracle database to Exadata. 5) Right now there RAC servers are installed without domain, I need to add domain name to existing RAC.
Today i noticed one problem with my database,my redologs switches in every 3mins,i also noticed there is no more transaction changes happening in database but still redo switches.

why redo switch happening,any internal problem causes redo to switch .
Create a table with 100 records.Then write a BULK COLLECT Cursor that can reduce the number of context switches by using a bulk fetch to query records in sets or all at once.
Note that serial number must reset after each 4 lot_num againt dpt_num. Not that where lot is associated in associated_with_lot there serial number must be same as serial number is for associated lot.
I have one table as per the attachment, with id(Primary key),level,name and Srno.Now I want to maintain Sr. if user transfers level 2 of one block (level 1) to another block.is it possible through any oracle function.
I want to conditionally re-arrange the serial. Sample test case is as below.
DROP TABLE t1; CREATE TABLE t1 (
[Code].....
SQL> Select * from t1 order by no;
NO T ---------- - 1245 R 1246 N 1247 N 1248 R 1249 R 1250 R 1251 N 1252 N 1253 R 1254 R 1255 N
11 rows selected.
Required output is
OLD_NO T NEW_NO ---------- - -------- 1245 R 1245 1246 N 1247 1247 N 1251 1248 R 1248 1249 R 1249 1250 R 1250 1251 N 1252 1252 N 1255 1253 R 1253 1254 R 1254 1255 N 1256
Scnario is to add 1 in no. field but no.s having type 'R' will remain unchanged. e.g. Record no. 1247 is changed to 1251 because 1248,1249,1250 have typ 'R'.
I need to query above data with a column "Srl_Num". Its serial number and serial should like 'AA1','AB1'. In serial number is last digit 1 is "Ctn_Num" Column Value. First Letter 'A' of serial number is 'A' and second letter of serial number will change. When it reaches till 'Z' Then first letter will change.I mean if serial number is 'AZ1' Then next serial number will be 'BA1','BB1','BC1' and so on.
How can i print serial no of records in sql query? I know I can achieve this with selecting rownum but it gives wrong data if used with group by like below
select rownum,deptid from emp group by rownum,deptid order by rwnum
how do you generate serial numbers? i have an invoice where i have to add items, so i want the numbering to start from 1 everytime i start a new form and increment by 1 as i i enter a new record. For this i have put my code in when-new-record-instance but problem is if i delete a record and enter a new one, the serial number starts from the nex number.
For ex. if i have 4 items with serial numbers 1, 2, 3, 4 and i delete the item at no. 3 and add a new item , the serial number comes as 5.
i want to get serial numbers in oracle forms. i have one data block with 10 rows and a non database display item with corresponding length as that of the original data block .
when ever i am executing the form i want to see the serial number generated in the display item and when i inserted a new item or row it should show the corresponding rownum.
eg:
empno name serialno 5 tom 1 4 tinil 2 6 sofy 3 7 john 4 1 albert 5 2 michel 6
Is it possible to communicate with a serial device (via COM1) with oracle forms / webutil? I am able to communicate in java using RXTXcomm, but I am having problems making a bean that uses it (getting security errors and yes, I have signed the jars).
Basically, I have a scale hooked up to my COM1 port and want to be able to send commands (zero and tare) to it and read the weight from it through a form or java bean.
I have form with master detail relation ship (invoicing form) the detail block is tabular, displaying upto 7 records...
Now my clients wants to show the serial number along with each record while feeding the data (this includes when insert, editing, deleting / clearing records) he wants to see the serial number as in MS access / MS techniques.
I tried to use the system variable to use :system.cursor_record; but this dose not works.(in insert/edit/delete/clear record)
My exadata quarter rack machine has two asm diskgroups, DATA1 with 5TB and RECO with 3TB. I'd like to resize RECO to 1TB and DATA1 to 7TB.
I know ALTER DISKGROUP RESIZE command, but my question is about resize RECO volume from 3 to 1 TB: is it supported by Oracle?? Let me know risks /issues with this resize?
