The connection pool DIMT_DB is running out of connections
I am facing an issue, the process instances created in activity are not getting routed to my work item. I found the following exception logged in engine DB at the time process instance was created,
The connection pool DIMT_DB is running out of connections ( 100 % of the pool is in use).
It is recommendable to expand the size through the Process Administrator.
can anyone provide me a solution to this issue?
the maximum pool size is 10. should it be increased?
does this issue occur when database connection is not closed properly?
Can anyone please share your ideas?
Thanks,

Re:Running out of connection pools one server
Hi,
We are running out of connection pools on one weblogic server only everytime in a 2 node cluster.
But the sessions are very less in the database when we faced the issue.
But this doesn't happen all the time it happens once in a month.
our configuration

<max-capacity>150</max-capacity>

Connection leaks and application is running out of connection
Hi All,
We have configured the SQL Database external resource for OBPM specific connection pool. All the business processes are using the Fuego.Sql package for the data base transaction calls. I have no clue how this package is managing the database connections. If more than 25 users perform concurrent testing, the application is running out of connections. Connection pool configuration details as below.
Maximum Pool Size : 500
Maximum connections per user : 50
Minimun Pool Size : 0
Connection Idle Time (mins). : 5
Maximum Opened Cursors : 1000
Please share your thoughts on how I can track and fix this issue. Also please let me know the answers below.
1. Is there any way to find out the stats about the connection pool
2. If I configure the remote JDBC that points to J2EE datasource, would that fix this issue.
I appreciate your help.
Thanks,Can anyone please share your ideas?
Thanks, -
Sybase ASE 12.5.4 EBF 14124 ESD#4 running out of connections
I am working on a web application which works on SQL sever back end as well as Sybase ASE 12.5.4 EA server. Our project main focus was to move everything to sybase backend.
Earlier there were 2 databases, the app was connecting to - db1 on sql server, and db2 on sybase. Now we have created a separate namespace within db2 in sybase. So application only connects with db2, but with different users and in separate schemas.
Application is in java and connecting to db server using jcon3 driver library. It is using SybXADataSource driver class (provided by jcon3 jar) to connect to the server. Till last week application was able to connect to the server, everything was working fine (though I must say that code is still not optimized to use connection pools etc., I am opening a connection, and closing it for every request).
For sometime, I have been facing an issue from the server- login failed, try again. In the server error logs I found it was throwing an error- "Error 1601 Severity 17 state 3: no user connections available to run the process" I checked for available connections (using sp_configure), allowed connections are 900, and total active connection at the time this error shows up is typically between 30- 100 (using sp_monitorconfig). Seems like this is well within limits.
Also yesterday, I did one more exercise, I restarted the server and logged in as sa from isql console only. Logged out and logged in again afimeter 20 minutes (no application connection was made), and isql login again gave this error. So I am inclined to think that something could be wrong with server configuration as well. Server is on linux red hat.
I have searched all the db forums and SCN website as well, and all of these refer to one resolution of increasing the number of connections, but as from my observation regarding that, I do not think it is an issue.
Any help would be greatly appreciated!!During your sa/isql test, how did you exit from your sessions? Did you type 'exit + go', hit ^S, hit ^C, something else?
Are you running your sa/isql test from the same linux host where the ASE is runing, or from another host on the network?
Is your isql session connecting directly to the dataserver or are you going through an intermediary service?
Are there any login triggers on your sa account? (See the output from sp_displaylogin sa)
Could you run your sa/isql test again, but this time:
session #1: log in as sa using isql; stay logged in
session #2: perform your login/logout test using sa + isql
session #1: periodically run 'sp_who' to see the active connections; does the list of connections grow over time? -
Hello,
I think I'm having the same problem ..

We are using SP8 but the problem seems to be still there!

Hi Joe,
Good news; bug ISOLATED and FIXED! First off, I was able to determinethis bug only manifests if
we are running clustered apps. under a single app server, this bugdoes not appear, and under
clustered app this bug always appears.
Furthermore, I appologize if I may have lead you on a wild goosechasewith all the subsequent
patches you sent me. As it turns out, when I received each patch Ihanded it off to our tester, who
applied the patch and probably only bounced a node in our server
cluster
before testing, hence
getting negative results. Today I applied your latest patch,
clean-bounced
all the nodes, and the
bug disappeared! Thanks Joe!
Now the 2 questions of the day:
1) Is your latest patch production worthy? Can I apply it on ourlive site?
Yes.
2) If not, when's the next service pack coming out with this fix?It will be in future service packs.

Hi Joe,
We tried it and found the same exception raised, except for this
time it took a lot longer to
bug
out; the server hung for almost 2 minutes before dumping the

However I was just
informed by another developer that we may have a recursive bugon our side, and that we are
doing a
non-terminating db search. Perhaps this is causing this
out-of-resource
allocation bug, i.e.
our
bug exposed your bug! I'm sure once we fix our recursion bug we
won't see this again, but maybe
something should also be done on your side that'll handle thismore gracefully...
I'll let you know what happens once we fix our bug; thanks forthe help!
DO let me know. In fact, please use the attached jar (in place ofall the others:-)
because the line ResourceAllocator.java:561 is not executable code.There may be a
JVM problem... I'm fairly sure there's no way our code can causean NPE in this

Hi.
The server won't let an EJB wait indefinitely for
a connection to become
available in a pool. All the while it waits, it iscommandeering one
of the fixed number of execute-threads, doing nothingwhile the thread
could possibly run another task which already hasit's pool connection,
and could release it if it ran. The default waitallowed is 5 seconds
the server decides to devote it's resources to thework it can do, and
not let overflow requests cause an unintentionalor malicious denial-
of-service attack. The fundamental solution is tosupply enough DBMS
connections to serve the load you have.

ConnectionPoolDataSource - running out of Connections..
Hi
I have a same problem as described in this thread
http://forum.java.sun.com/thread.jsp?forum=136&thread=560645&tstart=0&trange=15
I have Q42004 Beta J2EE SDK, and am using MS SQL 2000 databse server with jTDS 0.9 (jtds.sourceforge.net) JDBC driver...
I have a very simple servlet that gets a DataSource from the JNDI, gets connection , does some stuff, closes connection....Pretty basic....After a while I get the following error

ZHi
jTDS 0.9 does not have XADataSource implementation but it has DataSource implementation.
If I use the DataSource imlementation I still get the "out of connections" problem....
This same application did not exibit any problems on Updte 1.
The code of my servlet is pretty big but here are the relevant snippets:
private Connection getDBConnection() {
DataSource ds = null;
Connection conn = null;
try {
Log.info(this.getClass(), "Attempting to use ServiceLocator to get DS from JNDI...");
ds = ServiceLocator.getInstance().getDataSource("jdbc/coiDB");
Log.info(this.getClass(), "Attempting to get connection...");
conn = ds.getConnection();
} catch (Exception e) {
Log.error(this.getClass(),"failure...!");
Log.exception(this.getClass(), e);
return conn;
private Employee getEmployee(int empID) {
Employee existingEmp = null;
PreparedStatement pstmt = null;
ResultSet rset = null;
Connection conn = getDBConnection();
try {
pstmt = conn.prepareStatement("SELECT * FROM EMPLOYEE WHERE ID = ?");
pstmt.setInt(1, empID);
rset = pstmt.executeQuery();
if (rset.next()) {
existingEmp = new Employee(rset.getInt("id"), rset.getString("fname"), rset.getString("lname"), rset.getString("location"), rset.getString("department"), rset.getString("phone"));
existingEmp.setCreateTS(rset.getTimestamp("create_ts"));
} catch (SQLException e) {
Log.error(this.getClass(), "Failed DB operation while checking for existing employee");
Log.exception(this.getClass(), e);
} finally {
DBUtils.closeResultSet(rset);
DBUtils.closeStatement(pstmt);
DBUtils.closeConnection(conn);
return existingEmp;
}The DBUtils I use is just convenience static class that wraps regular JDBC calls into try catch block and ServiceLocator is a BluePrints pattern straight from AdventureBUilder 1.0.1. Employee is a my model/subject class.....
Thanks

Why is the battery on my iphone running out so quickly
Since the last update my iphone runs out of battery power in half the time it used to. I have followed all the advice about turning off anything that consumes energy but it has had no effect. I also keep getting a no service message which can only be fixed by resetting my next work connections.. I am starting to lose my enthusiasm for apple and I think my next phone will be an android. Can anyone suggest how to get my battery power consumption back to normal?
If you have already followed all these suggestions ...

ORA-30928: "Connect by filtering phase runs out of temp tablespace"
i have created a query that is sued to display a data in a label. This particular query will then be stored into a program that we use. The query runs just fine until this morning when it returns the error ORA-30928: "Connect by filtering phase runs out of temp tablespace". I have Googled and found out that I can do any of the following:
Include a NO FILTERING hint - but did not work properly
Increase the temp tablespace - not applicable to me since this runs in a production server that I don't have any access to.
Are there other ways to fix this? By the way, below is the query that I use.

I am using Oracle 11g too.
Thanks for the help everyone.Hi,
The documentation implies that the START WITH and CONNECT BY clauses should come before the GROUP BY clause. I've never known it to make a difference before, but you might try putting the GROUP BY clause last.
If you're GROUPing by LEVEL, what's the point of SELECTing MAX (LEVEL)? MAX (LEVEL) will always be the same as LEVEL.
What are you trying to do?
Post some sample data (CREATE TABLE and INSERT statements) and the results you want from that data, and somebody will help you get them. -

Is the iPad air meant to run out of battery even when it is charging?
Is the iPad air meant to run out of battery even when it is charging?
Depends on the charger. The 12 watt charger that came with the iPad should be able to charge faster than the iPad drains the battery when in use. But other chargers may not provide enough power to efficiently charge the iPad. The best way to charge any iPad is to use the charger that came with the iPad.

Is it possible to store txt message history on the memory card? - Always running out of txt storage space on my phone. I've never gotten close to being able to store 300 messages as indicated on pg 58 of the manual, so I must be missing something.
I might get 35 or 40 and then get storage limit warningsA_Ohmstede,
I know it can be frustrating seeing that inbox get full and having to delete
stored messages. I do see in the Samsung manual where it advises that it
will store a maximum of 300 messages on the phone. The number may lower
if there are pictures messages and other things being stored on the device.
Have you checked your total Memory available in Settings and Tools? How much is
currently available? Please let us know these details and we may be able
to help further!

ASMCMD-08103: failed to connect to ASM; ASMCMD running in non-connected mod
Hi,
I am facing below problem.
ASMCMD-08103: failed to connect to ASM; ASMCMD running in non-connected mode
ASMCMD-08102: no connection to ASM; command requires ASM to run
Probable reasons are:
1. ORACLE_SID is not set properly
2. ASM instance is not running.
But my ORACLE_SID is set properly and ASM instance is also running...
What else i can check?
Thanks,======================================================

Connection pool running out of connections
Hi all,
I am using Oracle's connection pool implementation:
OracleConnectionPoolDataSource dbConnection;
OracleConnectionCacheImpl connectionPool;
and tomcat 3 and 4. Sometimes on Tomcat 4 (Linux) I see that the connections are not being reutilized and therefore I run out of free connections. The same application runs fine on NT and Tomcat 3 and 4. I checked all my methods and all have a close(connection) in my finally{} and besides this the problem only happens once in a while and the program is using the same methods all the time. Anybody has a clue about what could the issue be?
Thanks,
A.have u tried setCacheScheme?

JCo Connections in WD Model running out
Hello,
we have WD application that uses RFC model.
During a load test we have observed that the connection
pools are running out of JCo connections. The result is a an error message in the trace file
and Http 500 response code to the end user.
Number of concurrent users: 20
Max Pool Size: 20
Max Connections: 20
Exception:
[code]aused by: com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool ME_LP_MODELDATA_TSTWEB1_PT_useSSO is exhausted. The current pool size limit is 20 connections.

at com.sap.tc.webdynpro.modelimpl.dynamicrfc.AiiModel.getCurrentlyUsedJcoClient(AiiModel.java:191)[/code]
Questions:
Is it necessary to have equal number of Max Connections as
number of potential concurrent users?
Or is there a way to manually release not used connections?
Best Regards, MaikHi,
It is not necessary to create as many connections as there are concurrent users.
We have to handle the scope of the connection properly and also close the connections once we complete the task.
