View 4 RepliesWe have a Data Source with min_pool_size (10) and max_pool_size (20). A Data Source is by default a connection pool. By starting a transaction we are retrieving a connection from the pool (i.e., opening it to retrieve data, perform queries, inserts and updates). Our application server is JBoss. An application workflow uses many transactions to build a product. The same connection is not used by the application for the entire workflow; but, it uses and returns them to the connection pool. We do not use Java syntax like "rs.close():"... this is performed by iBATIS.
On the Linux side when we execute a "ps" command (ps -elf|grep -i ora) we see all the Oracle processes. A further refinement of that command (ps -elf|grep -i local=no)shows a list of the "waiting" connections in the connection pool. The DB may be queried with the following syntax:
SELECT schemaname, sid, serial# FROM gv$session where schemaname = 'APP_USER' order by SID;
A list of connected sid and serial numbers is returned, identifying which connections are in use. From here we are able to force the connection to trace by executing the following:
exec dbms_monitor.session_trace_enable(249, 6595, TRUE, FALSE); ! 249 and 6595 being SID and Serial# from query above
There should be no need to execute the inverse, since the connection is returned to the pool when the transaction is committed or rolled back.
exec dbms_monitor.session_trace_disable(249, 6595);
We are trying to trace in order to use the Quest Benchmark Factory. Their instructions request the following syntax be applied to each session:
alter session set events '10046 trace name context forever, level 4';
and again, the inverse should not be necessary.
alter session set events '10046 trace name context off'
When it became too cumbersome to alter each session as it appeared, we issued an "alter system" to monitor (trace) everything. The trace files filled the disk, and four hours of testing was stopped two hours in. Doing a system level trace is probably not a good idea.
My first inclination was to create a post-logon trigger to set trace in the session; however, these connections, coming from an JBoss connection pool, do not logon each time, and I presume that they are not all the "same session".
We opened a support ticket with Quest last Friday and do not have an answer yet. This was the third ticket with them, the first to get Benchmark Factory installed (the original installer did not work). The second ticket was to setting up a shared directory on Linux with a folder on Windows, a setup configuration required by their tool. The third ticket to address this issue.
They needed to contact "the developers" to answer the last two questions. Their latest suggestion is to fix ticket two so we "won't need to trace" anything. How do I set trace in these connections?
I want to increase my shared pool. my SGA values are as under below.

I have a problem with one table.. First of all:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
The problem table resides in a locally managed tablespace. About 10 millions records is added in this table every day. After 36 hours all these records moved to another (partitioned) table, so the size of data in the problem table always about 75 Gb. But the size of table is reached 157 Gb today, and it still growing. The results of dbms_space.space_usage are showed below:
Size of blocks with:
0-25% free space: 4726784
25-50% free space: 17301504
50-75% free space: 24920064
75-100% free space: 102418669568
full blocks: 54761594880Thus, a lot of blocks have 75-100% free space but the table constantly growing: during last 9 days the size increased from 123 to 157 Gb.
how to stop the table growing? It there any way to limit the table size in locally managed tablespace?
I'm using TimesTen Release 11.2.1.9.8 (64 bit Linux/x86_64) 1. is there any limit in size for a single table. How much a table size can be increased? 2. Is there any limit in number of records in a table?

I'm looking for 3 simple things.
1) A reverse engineering tool that I can point to an Oracle schema and get a "baseline" script to re-create that schema from scratch, with decently formatted DDL files (1 per object) neatly organized in a directory tree (by object type) and called in the correct order. Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to populate (insert) those tables as part of the script.
2) a diff tool that I can point to a pair of Oracle instances (source and target) containing a given schema and get a "delta" script to alter the target schema so that it becomes identical to the source schema. If data loss occurs on the target instance (i.e. drop a column) I would like to find a warning comment inserted in the script (e.g. "-- Attention: data migration DML needed here?"). Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to update (delete, update and insert) the data in the target tables to become identical to the contents in the source tables *without* deleting and re-inserting all rows (or dropping, recreating and repopulating the table).
3) I would like the above two tools (that, as you will have recognized, are basic to putting your database design under version control) to be open-source, with a command-line interface and a vibrant community backing them.
The problem is that this connection errors when I try to connect using my SQuirreL client. My developers want to connecting using the SID or the SERVICE_NAME and by using the "New Method" syntax, not the "Old Method" syntax. According to the documentation the "New Method" syntax works with the SERVICE_NAME or the SID. The "Old Method" only works with the SID.
# Host name is vmwwin7634.na.SAS.com
# SID is sting2
# SERVICE_NAME is sting2.na.sas.com
PROBLEM using SID errors ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2
THIS WORKS using SERVICE_NAME ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2.na.sas.com

I'm fighting with a fairly large set of dynamic queries created by some developer (often SQL is over 2MB) accessing plenty of tables having something like 1000 columns...
Formatting of such query takes ages in Toad while is pretty fast in Oracle SQL Developer... SQL developer is running plenty write operations in local app data directory... moving it onto a ram-drive didn't worked how I could optimize Toad's formatter?
I'm often accessing a small table which has 100 columns of type VARCHAR2(4000).
The problem is that I cannot see the results of such query as Toad is throwing "out of memory" exception. How to deal with that?
I'm a Data Manager recently hired at a small company that uses InForm as our data management tool. We are currently not set up with any type of SQL tool to query the database. Consequently, I feel like I'm trying to clean data with one hand tied behind my back. I have two questions:
1) Is there any sort of built in feature in InForm for using SQL statement to query the data? (I'm not really a fan of the built in Cognos feature.)
2) Any tool that is easy to install/configure?
I'm facing some resistance here, so I'm looking for a really easy/cheap solution. I've used SQL Developer before, and I know that's free, but is it easy to set-up?
