We have a requirement from the customer to start using data and index compression in our 11g database.. Is this something available in Oracle 10g,11g without any additional costs? We are not sure if this will work with our application so we will have to test it in-house, is it possible to compress the existing table data/index to test it out?
View 3 Replies1)i have 2 SWP TABLES. while dropping a column, i am getting error -
ORA-39726: unsupported add/drop column operation on compressed tables.
2) when i checked compression status, those were not compressed. But as per our code standard, SWP tables should not be in compress mode.
OWNER TABLE_NAME COMPRESS COMPRESS_FOR
------------------------------ ------------------------------ -------- ------------
NOVAR PAYMENT_SWP DISABLED
OWNER TABLE_NAME COMPRESS COMPRESS_FOR
------------------------------ ------------------------------ -------- ------------
NOVAR PREPAYMENT_SWP DISABLED
3) as a workaround, i compressed these 2 SWP tables with OLTP option, and then i was able to drop the column from these 2 SWP tables.
4) Below statement is correct or not ?
IF A TABLE USING BLOCK LEVEL COMPRESSION, THEN this error will come - ORA-39726: unsupported add/drop column operation on compressed tables.
if above statement is correct, then how to find out whether table data is using block level compression ?
5) we have DBMS_COMPRESSION.GET_COMPRESSION_TYPE. using this i just tried to find out, but i am getting "1" as output. I am not getting the exact meaning of it.
confirm what is the conclusion on this ?

I start my database and suddenly got this error:
ORA-00371: not enough shared pool memory, at least 72102521958 bytes
How to fix? I use startup command only and shutdown when shutdown the database.
Our database size is 100GB and i removed few records from a table and rebuild the index.The size of Index reduced considerably after Index rebuild but now i see our database size increased to 115GB.I know online rebuild creates second index which is also removed after the build is finished then why the increase in database size?Is there a way so it shows up more space ?
select sum(bytes) from dba_segments where owner='abc' and segment_name='abc_index_1';
8GB
ALTER INDEX abc_index_1 REBUILD ONLINE ;
select sum(bytes) from dba_segments where owner='abc' and segment_name='abc_index_1';
2GB
How to verify if rebuild an index is required in database.

View 10 Replies View RelatedI need to move my indexes (around 300) from data tablespace to index tablespace. What's the best way to do it?
View 9 Replies View RelatedI had created a Primary key and wanted to compress as per my senior instructions.Below are my results the size increased after compression.
select compression from dba_indexes where index_name = 'TEST_IDX';
Compression
----------
DISABLED
select sum(blocks) no_of_blocks, (sum(blocks)*8192)/(1024*1024)size_MB
[code]....
We ran a compression on the primary key index TEST_IDX
ALTER INDEX SCOTT.TEST_IDX REBUILD INITRANS 15 TABLESPACE DATA_01 COMPRESS;
ANALYZE INDEX SCOTT.TEST_IDX VALIDATE STRUCTURE;
Now when i ran the below select statement:
select compression from dba_indexes where index_name = 'TEST_IDX';
Compression
----------
ENABLED
select sum(blocks) no_of_blocks, (sum(blocks)*8192)/(1024*1024)size_MB
[code]....
As you can see after compression the blocks and size has been increased, but i ran for many tables and other indexes, we observed the blocks and size was reduced by 50-70%, i am not sure why this happened to the index compression.
I have a global index and I want to convert it to local index.Is there a way to recreate local index with out dropping the global index.
I can create a local index first and then drop the global index. But is there a way to create it with out dropping the global index, just convert it.
How does standard vs advanced handle index compression? Is there an advantage to having one vs the other besides the incurred cost?
View 3 Replies View RelatedI have setup a RAC machine of two nodes on Oracle 10GR2(with 10.2.0.4 Patchset). All setup went well. I am able to connect one node from sqlplus but the other node is connected to idle instance. I tried to startup the database with mount and nomount option but it fails. Following is the error :
SQL> startup nomount;

I am using ASM and it is running on both nodes even I am able to connect the SQL prompt from it. I am able to view the diskgroups I created from the second node but through "asmcmd" option I can't go inside the disk group. It gives :

asmcmd: diskgroup 'data' does not exist or is not mounted
On first node, everything is fine and I am able to import the database on it, as well.

OS: AIX 6.1 64bit
DB: Oracle 10gR2 (10.2.0.5.0)
What we did is..
1. Install patch 6613550 (./rootpre.sh)
2. Install 10.2.0.1 for AIX 64-bit
3. Install 10.2.0.5 Patch Set
4. Create Database
5. Created/Setup LISTENER and TNSNAMES (test connection successful)
After installation of database, everything went well until we tried to restart the server, what happened is that we cannot start the listener, the error was:
TNS-12555: TNS:permission denied
TNS-12560: TNS:protocol adapter error
TNS-00525: Insufficient privilege for operation
IBM/AIX RISC System/6000 Error: 1: Not owner
What i did to resolve this problem is to change the owner of /tmp to oracle, after that i was able to start the listener. ($lsnrctl start) The problem is that our sys admin said that the /tmp directory is being used by the OS and it's owner must be root. But if i return it to root, the listener will not start again. (After server restart)
BTW, our /tmp has enough space so we did not perform the following steps from the installation guidelines:
$TEMP=/directory
$TMPDIR=/directory
$export TEMP TMPDIR
I was thinking if that we must make a temp directory for oracle and set it in the profile, or change the owner to root again and perform this:
$chown -R oracle:oinstall /tmp
$chmod -R 777 /tmp

We have an Oracle Server database of Size 50 GB having 10 GB Data. And Planning to have a new Database Server of 200GB . So my question is after moving all the 10 GB data to 200 GB Database Server, will the performance of the system come down? Will it reduce the speed?

Basically structure two database is same, but database A have data real time, database B is stand by server. Now i want to synchronize all data of database A to database B. What should i do?
whether Oracle has any capability of automatically checking which lossless compression algorithm it should apply by analyzing a data stream on data load? Does Oracle have any compression advisors/wizards that would make recommendations as to type and level of compression?

On a SAP system, am trying to drop six indexes, largest is 300MB and smallest is 50MB.
I tried running drop index sapusername.index_name on the 50MB index via SQL*Plus and it seems to be taking forever. anything I can check on the database on why it is taking such a long time?
I can leave it to run overnight but worried that when I come back the next day, it will still be hanged. Is there any quick way of dropping the index, .i.e. drop immediate ...
Am not using SAP's BRTOOLs as it is also hanging from there and the SAP-ADMIN had approved for the DBA to drop it from our end instead.
I am working on Index issue and need to validate the structure of the index. Does validation lock the Index ?
Do we need downtime or we can do it in normal working hours.
