MySQLNonTransientConnectionException and Reached maximum capacity of pool
Hi. I'm using jedeveloper 11g and weblogic 10.3x and I'm quite new at this. I have an application with basic CRUD functions deployed in my weblogic server with a MySQL database as its data source. It was running well until we encountered an SQL exception error. Here's the log of the error:
BEA-001112 - Test "SELECT 1" set up for pool "EvCoreMySqlDS" failed with exception: "com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after statement closed.".
After some time, we tried accessing the page again. This time, it was now running perfectly well again. Then sometimes it throws this error with a blank page.
BEA-000627 - Reached maximum capacity of pool "EvCoreMySqlDS", making "0" new resource instances instead of "1".
Can anyone help me regarding these two errors? Are these two errors related? Could you please enlighten me how did these occur? And most importantly, how can I fix this? Thanks.

Hi Kal,
we already enabled Inactive connection timeout is 900 still its throughing the info.

Outage with BEA-000627 Reached maximum capacity of pool
Hi , i am having an outage in the application and at the time of outage i am seeing a lot of <BEA-000627> <Reached maximum capacity of pool > messages.
Now just before i am getting <BEA-000627> <Reached maximum capacity of pool > i have seen messages of :
<BEA-001128> <Connection for pool "iemphsysOracleCP" closed.>
there are 45 such connection closing messages .
the initial capcity for connection is 25 and maximum capacity is 75 , 50 threads are allowed to run.
just after closing the connection by weblogic , i see only one message of connection created , but after that i see messages of reached maximum capacity.
The shirking is allowed and shrinking frequency is 900 secs, now the connections are closed when there are connections existing in the pool above the initial capacity and they are not being used, so weblogic closes the connection, in my problem the connections are closed and just after that one connection created and i see messages of reached maximum capacity , if connections are closed then these should be able to be created again and i shoud not see that maximum capacity message.
The test connections frequency is also 0 and testconns on reserve set to true , also testconnon release is true.
Remove infected connections is enabled.
how it can reach maximum capacity while just before that it is closing the connections ????gaurav joshi wrote:

show me the whole pool definition? There's no need for shrink.
I would recommend turning it off. I would set initial capacity
and max capacity to 50. I would turn off test-conn-on-release.
That is a waste of performance.

Reached maximum capacity of pool "eis/PRAdapterCF", making "0" new resource
Hi All,
We configured weblogic with pega. I am getting below error. Any idea ?

WLS 10.3.0.0 Solaris SPARC and DBMS Oracle 10gR2 connection pooling issue
Hi all,
we are currently testing Weblogic Server 10.3.0.0 in order to migrate our production system from WLS 8.1 to it.
While testing the new setup, we encountered some strange behaviour of the connection pooling within WLS.
We configured a XA-Connection pool to our DB (Oracle 10gR2) by using
a) the Oracle XA-thin-driver delivered within WLS 10.3.0.0
and alternatively
b) the Oracle 11.2.0.2 OCI-driver of the Oracle 11g database client.
We´ve got the same issue with both variants. We defined an initial capacity of 5 connections and a maximum capacity of 30 connections.
Our application is running flawlessly using the connection pool, but the amount of active sessions between the application server and the database server is increasing rapidly and the maximum capacity is exceeded. We are seeing up to multiple hundreds of sessions from the application server to our database server. Obviously the connections aren´t cleaned up.
We are using the following settings for the JDBC-Connection:
initial capacity = 5
max. capacity = 30
Capacity increment = 1
Statement cache type = LRU
Statement cache size = 10
Test connections on reserve = true
Test frequency = 120
Test table name = "sql select 1 from dual"
seconds to trust an idle pool connection = 10
shrink frequency = 0
connecttion creation retry frequency = 120
login delay = 0
incative connection timeout = 10
max. waiting for connection = 2147483647
connection reserve timeout= = -1
Ignare in-use connections = true
pinned-to-thread = false
remoce infected connections enabled = true
Does anyone have an idea how to track/solve this issue?
Kind regards
MarcHi Joe,
we´ve tested with the thin driver using an initial capacity of 5 and a maximum capacity of 15. During our tests (in a very short time period) the maximum capacity has not been exceeded. But we saw some exceptions in the managed server logfile which made us curious.
When these exceptions are occuring, a new connection to the database server is established. We are seeing for a short time a total count of 6 connections which is immediately decreasing to the initial capacity of 5. We will do some further testing over the next hours and monitor the connection usage.
The connection we are dealing with is the one called "ZDB2".
This is an excerpt of the logfile:

Datasource Maximum capacity in Cluster
Hi,
I have configured a datasource and assigned maximum capacity of 10 and initial capacity to 2 and targeted it to all server in a clusters(node 1 & node 2).
now how the connections will be utilized in the clustered mode. Both the node will have maximum of 10 connection limit
or each node will have maximum of 10 connection limit ? please clarify me.
Thanks
KKMaximum Capacity
Maximum capacity is number of allocated session in database side for WebLogic Server divide by number of WebLogic server. Example, DBA allocated 500 session for WebLogic server which has 5 server, so this config value is 500/5 = 100
Initial Capacity
Initial capacity mean number of initial session created when data source started. Recommended value for Initial Capacity is equal to Maximum Capacity size database connection pools. In this case WebLogic never increase the number of connections when it needed by application. Negative impact for this case is increase DB load although only few session use by WebLogic, but if impact in database side is not significant its work well.

Satellite M110 - RAM upgrade and maximum capacity
I have a Satellite M110 and would like to upgrade the RAM as much as possible. It has the original RAM from the factory. The manual gives me the model numbers for memory depending on the model of the computer - ie either PC2-4200 or PC2-5300. How do I tell which one I have? I can't see either of those numbers anywhere. Is 1GB the largest RAM this computer will take?
Hi lenore104,
The maximum RAM capacity is also depending on the chipset. Furthermore the maximum RAM capacity can also be found in user manual.
Did you find this information?
The specifications of memory modules you can find on memory module itself. So if you remove the current memory module you should see a sticker on it with technical information such as PC2-4200.
If you post the exact model number of the notebook we can search on Toshiba website for maximum capacity. -
Toshiba Satellite L750-1LM PSK6RE-01N00RG5 Ram Upgrade and Maximum Capacity help

Through a command in linux I found it is 16GB (8gb and 8gb)Is there any limitation in speed?In my ram slots says 1.5v if I buy 1.35v will be a problem? Is this ram compatible with my laptop?RAM CORSAIR CMSO8GX3M2A1333C9 SO-DIMM 8GB (2X4GB) PC3-10666 DUAL CHANNEL KIT Size: 8GB (2 x 4GB kit).

I am going to build a RAID5 config in my Cisco/Linksys NSS6000. I am going to buy (4) Sata drives but wasn't sure if there is a limit to the size of drives that the NSS6000 can handle. I was thinking of getting (4) 500gb drives but am seeing 1.5tb drives becoming cheaper and am thinking of getting 4 of those instead. Anybody know the limitations on the NSS6000?

UnsyncCircularQueue$FullQ Queue exceed maximum capacity of: '65536' element
dear friends:
Does anyone knows the problem like this <BEA-002911> <WorkManager ClusterMessaging failed to schedule a request due to weblogic.utils.UnsyncCircularQueue$FullQueueException: Queue exceed maximum capacity of: '65536' elements
weblogic.utils.UnsyncCircularQueue$FullQueueException: Queue exceed maximum capacity of: '65536' elements
why this happend and how to solve it?
thanks a lot!Hi,
Weblogic has a maximum storage for Pending Request queue configured at 65536. At this point, it will stop accepting incoming request to your Server Socket port.
This means that your Weblogic server / JVM very likely has depleted its internal Thread Pool triggering Weblogic to start queuing incoming requests; eventually reaching its maximum capacity.
From a resolution perspective, you will need to investigate the root cause, Thread Dump generation and analysis will be required in your case.
Please generate a JVM Thread Dump (kill -3 <pid> for UNIX OS) and share detail on Thread contention / problem pattern.
Thanks.

Channel has reached maximum concurrency (5,000 concurrent messages)
Hi Experts,
I have executed a scenario: IDocs to AS400 (JDBC Adapter). Some IDocs were processed succesfully but some are giving the following error.
"com.sap.aii.af.ra.ms.api.RecoverableException: Channel has reached maximum concurrency (5,000 concurrent messages) and no free resource found within 5,000 milliseconds; increase the maximum concurrency level"
Can any one faced this problem? Please do needful...
Regards,
Ramesh.Hi,
This error occurs when the channel has only few (minimum 1) resources in the pool(to connect the DB in parallel) and the messages load to that channel is high. Hence, channel will reach to maximum concurrency( minimum 1, by default). In this case, you can increase this maximum concurrency value to higher value (could be 3 to 5) and check whether the issue is happening still.
Hope this feature implementation will solve your problem.

Problem with reached maximum number of connections to database
Dear Experts,
Our Production system was not responding properly last week.
The below was the reply from the Basis team.
"It seems that we have again problem with reached maximum number of connections to database. We have extended this number to 100 this year and now it seems that it’s not enough again. It seems that something is running on Production, which takes over too many connections."
They have increased the number to 200 as a work around.
Do we have any means to find out, which component or application is causing the issue.
Please advise me if any better way is available to correct the issue.
Please see the below trace.

Thanks and Kind Regards,
JelbinStop all instances(including DB) and start again, Hope it should work.
It may happened that jar has not been synchronized with the database and may be version mismatch with the java.

Hi,
The queue in question here is not a JMS queue. Instead,
this is the "execute queue" of jobs waiting to be
serviced by a thread in its thread pool.
I think the size of these queues is configurable on the
thread pool. Note that if dead-lock is locking up threads
and causing the problem,
you will likely need to increase the number of threads
or dedicate server-side resources to their own thread pools
rather than (or in addition to) increasing the size
of the execute queues. (A thread dump helps
in diagnose dead-locks.)
Likely this error is on a server side thread pool, so
there should be warnings/error messages in the server logs
that describe what is happening.

Channal Reaches Maximum - Urgent
Hi all
when i start my Weblogic 81 sp2, MQ Channal reacheds 92 connection.
why its increase?.
can u explain.
i am using IBM MQ Series 5.3 as a foreign JMS server.
and i have 8 MDB to lisiten queues and i defined 8 channal only. but when i start weblogic 81 server(Production Mode) , that time channal connections are reaching 90+, than its keep on increasing.
plz let me, how to rectify the pbm.
thanx n advance
regards
muruganandamI presume that the MDBs in your server are set up to dequeue from MQ. So, when you boot the server, they connect to MQ and they start receiving messages. How do you have them configured? This will control how many connections are deployed for the MDBs.
The "max-beans-in-free-pool" parameter in the descriptor of the MDB sets a maximum number of connections for each MDB that you deploy. The server limits this number to one-half the total number of threads in the server for each MDB, but if your server is running with 16 threads, and max-beans-in-free-pool is larger than 8, then you'll have 8 connetions for each MDB.
(Plus, that means that WLS will open eight JMS connections per MDB. How many "channels" MQ opens with those either JMS connections is something that only IBM knows.)
If you look at your MDB descriptors and reduce "max-beans-in-free-pool" for each MDB, you can reduce the number of MQ connections that are created. -
How do I add new Apple ID as it said it reach maximum
Please tell me how do I add new apple id as I already added a lot and it's said that it reach maximum. I forgot my Apple ID password and can't recover because I cant ***** the email.
Easy. Open System Preferences > iCloud and sign in with the same Apple ID and password you used when you initially set up your MacBook Pro. Select the iCloud services you wish to use.

What's The Maximum Capacity of Mac Mail
Hi All
I am new in Mac world, I was using outlook in windows with many email, the email files around 3GB, I did the converter of emails by using outlook2mail application.
My questions are, how much the maximum capacity of mac mail, and now I am using mac mail with few emails, its working fast, if I transfer all my emails to mac mail (1000s emails, around 3GB) is it will work in same speed or it will work slow or die ?
Thanks
KhalidYou've asked an unanswerable question. To my best knowledge there are no limits, other than as Barney says the available space on your hard drive. Also, it's impossible to quantify it because email messages vary in size. Do you delete large attachments? Have you created new Mail folders Mail > Mailboxes Sidebar > +? I do have a friend who has over 20,000. If anything gets mucked up you can always rebuild a mailbox from your Mail menu > Mailbox >Rebuild.
