Error message "Maximum number of drilldown characteristics exceeded"

Hello,
an user created a Web report. In the navigation block there are nearly 100 selection fields. If you make either "drilldown in the rows" or "drilldown in the columns" you recieve after 50 drilldowns the error message "Maximum number of drilldown characteristics exceeded" and it is not possible to proceed further. Does anybody has got an idea what this can be?
Thanks!
Regards,
Christian

Hi Check SAP Note No -
Note 144478 - BEx: Termination/Message at 10th/20th drilldown characterstc
1. Terminations occur when you drill down a large number of characteristics at the same time during interactive navigation in the Business Explorer Analyzer (Excel).
2. In the global query definition, the system displays message 'Termination: the maximum number (10/20) of drilldown characteristics is exceeded' if the total of the characteristics and structures you are using exceeds
              - 10 objects in Release 1.2B
              - 20 objects in Release 2.0A/2.0B/2. 1C
              during the definition of a query.
Hope it helps

Error Message-"Maximum number of internal sessions reached"

Hi,
 In one of the User defined screen , we are getting error as
"Maximum number of internal sessions reached".
 This error is not coming each & every time.This screen is used to store the values in Z-table.
 This error is coming after entering 6-9 entries.
 What may be the problem.
 The code is as follows :
 when 'save'.
 INSERT zmmt001_grn_gate FROM wk_zmmt01.
 INSERT zmmt002_grn_item FROM TABLE it_zmmt02.
 IF sy-subrc EQ 0.
 COMMIT WORK.

 CALL TRANSACTION 'ZMMI001'.
 ELSE.
 ROLLBACK WORK.
 MESSAGE e000 WITH text-006.
 ENDIF.
Whether CALL TRANSACTION 'ZMMI001' statement having problem..
Pls give your suggestion on this.
Thanks in Advance,
Best Regards,

Hi
I agree on the reason of the problem, too. SAP limits the number of internal sessions. By calling the transaction with "CALL TRANSACTION ..." statement, you keep the current transaction's program data and open a new internal session. To handle things technically, SAP forces an internal session number limit.
The solution is to use "LEAVE TO TRANSACTION ..." which ends the current transaction session, rolls out the relevant program and then opens the new session.

Error message, Maximum number of windows open. How do I close windows on Droid 2 Global white?

I know this sounds like a simple question, in fact it is so simple that I can not find any writen solution to this problem in the on line help manual.
I'm new to the Droid (a former BB user) and am looking for the obvious answer.
Who knows I may eventually learn how to drive this thing....

Call off the dogs on this one. I dumb lucked the solution.
Thanks for any replies.

BEX analyzer -Maximum number of rows (65535) exceeded. Result is incomplete

Hello Experts,
I am trying to Run a report on BEx Analyzer.There are around 200,000 records to be displayed in the result.
I am getting the below error.
Maximum number of rows (65535) exceeded. Result is incomplete.
Message no. BRAIN675
We are on SAP GUI 7.X and Excel 2007
Is there any setting that I have to change inorder for BEX analyzer to display all the 200,000 records.
Also any memory setting for the result set to be changed ?
Please let me know your thoughts
Thanks
Doodle

Hi Doodle,
The rows limit for Excel 2007 is 1 million so this is not the problem with row limitation. It seems like you have opened the pre-excel 2007 workbook in excel 2007, check your title bar if it says "Compatible Mode". This will limit you to old standard of 65K.
May be what you can do is , save your file using save as option and try running the workbook.
Your new file extension will be .xlsx

Maximum number of columns 90 exceeded

Hi,
after implementation SP SAPKH60409 we have problem with ALV reports FBL1N (3,5).
When I choose a button "select layout" I get the message:
Maximum number of columns 90 exceeded ( Message no. 0K114). It is not true because the layout has less columns.
I have set an user parameter FIT_ALVC = 'X' and it solved the problem but halfway the only.
In FBL1N we can change display layout via "Switch list". The first uses FM REUSE_ALV_GRID_DISPLAY, the second REUSE_ALV_LIST_DISPLAY. In the first it works, but it doesnt in the second.
Did you identify such problems?
regards

We had the same issue occurring where message OK114 was being issued. We had loaded note 1566394 in our system but only had the first correction for this note. SAP applied a 2nd correction to this note on the 28th of March 2011 which has now fixed our issue. Get your developer(s) to check the ABAP include LKKBLF01. At line no. 5946 there is a message being issued "message w114(0k) with con_max_columns." The 2nd correction of the note puts this message within the following IF statement "if l_no_out_count > con_max_columns.". Hopefully this 2nd correction fixes your issue.

Essbase error maximum number of columns [1] exceeded [15]

I am getting Essbase error: maximum number of columns [1]exceeded [15]This message started appearing after HBR 3.5.1 installWhen I retireve from the same excel spreadsheet on a machinewhich does not have HBR installed it works. I do need to use HBRso, how do I resolve this?

Retrieving more than 500,000 rows in excel are you sure you are using the correct tool, sounds like you are just trying to data dump out of essbase, have a look at other export options.

Regards,

You should check alert log file on database like Alex told you.
And please post Error ;)
But If You can access +ASM, Or ...by the way... if you stop database ... try to check ASM diskgroup.
$ export ORACLE_SID=+ASM1
$ sqlplus / as sysdba
SQL> set lines 130
SQL> set pages 10000
SQL> select NAME, TOTAL_MB, FREE_MB from v$asm_diskgroup;
If your DISKGROUPs for archivelog on DB full... backup or delete them
(please start database mount mode)
$ export ORACLE_SID=DB1
$ sqlplus / as sysdba
SQL> startup mount;
SQL> show parameter log_archive_dest
backup archivelog
$ rman target /
RMAN> backup ARCHIVELOG ALL DELETE INPUT format 'ARCH_%d_%U' ;
or delete
$ rman target /
RMAN> delete ARCHIVELOG ALL ;
After that ...
$ sqlplus / as sysdba
SQL> alter database open
This justs my suggestion, if your database has the problem with ASM diskgroup full ... because archvielog...
By the way... please post your result from ASM query and alert log file
Good Luck

 void com.evermind.util.ThreadPoolThread.run()
Question:
- What is the cause of this error message? How to avoid?.
From the Oracle error message documentation:
ORA-00020 maximum number of processes (string) exceeded
Cause: All process state objects are in use.
Action: Increase the value of the PROCESSES initialization parameter.
Another alternative approach may be to configure your Connection pool and/or your ApplicationModule pool to optimize the use of
database connections and/or restrict the number of database connections used by the application. For example, if your application
has declared many root ApplicationModules (i.e. more than one ApplicationModule pool is in use) then it may help to enable the
jbo.doconnectionpooling switch so that each ApplicationModule instance in the pools does not maintain a dedicated database
connection while not in use. Another alternative if you are using the BC4J connection pool (not a JDBC datasource) may be to
restrict the number of connections the pool can create to < 150 with the jbo.maxpoolsize switch. However, please note that this
may have an impact on throughput.
- I intended to deploy my application to 9IAS server. Will the same problem occurs too?.
This is a database issue. So, yes.
Hope this helps.

Tellling the OpsTeam to ignore RMAN jobs that return errors is not an ideal solution.

So the fix, does not fix all occurrances.
Have found additional information, and you may be able to look at your errors too for more info.

Maximum number of mail processes exceeded

I've got problems with my mailserver. I already had them, but after a restart the problems didn't occur. From today after sys updates I have them back.
Some clients mostly iPhones can't connect to my mailserver.
In the system log I have the following error message:
Jul 26 15:07:49 miniserver dovecot[60]: Maximum number of mail processes exceeded (see maxmailprocesses setting)
I don't know where these settings are in a config file.
I also have problems with webmail, I I want to login I get an error message: Unknown error: Internal login failure. Refer to server log for more information.
Thanks,
Patrick

I found the config file and edited in: /etc/dovecot/dovecot.conf
Settings were: mailmacprocesses: 3
Changed it to 300 and voila.

"Maximum number of application files exceeded or file names too long"...help!!!

Hi there…
I am trying to create a game for my mobile.
The “problem” is that I have more than 500 swfs that I want to pack using the Adobe Mobile Packager. And I am getting this error:
“Maximum number of application files exceeded or file names too long”
How could I solve this problem?
Thanks everyone!
Cheers.
Leo.

500?? What are there so many files?
The problem is that the CAB format only allows for 300 files maximum, so there's nothing that we can do about that I'm afraid.

In my listener.log, I got this at 08:05 am:

Host SRVXXX is a server where a web app is and 192.168.1.1 is our firewall. May I think that this server was the one that made so many connections?
I checked alert.log, trc file and listener.log. What else can I check to determine what was the cause of this incident?

It could result from Denial of Service attack or trojan or virus infecting webserver

ASM maximum number of processes (300) exceeded

Hi Everyone,
My Oracle database is 11g r2(11.2.0.2.0) and linux version is redhat 5.5.
In ASM one of our diskgroup getting full. so we added 5 disks to diskgroup with size of 545 GB lun(disk) each..succesfully added diskgroups but while rebalancing is going on ASM instance got stuck and node got hanged up and from application side process got stuck up and thrown with the below error from alert log, for temporariy solution we rebooted the first node.

Hi Jos
--> How to calculate ASM Parmaeter process? with which view i can get the information?
-->I cheked with below command by connecting ASM instance show below like 300 process .But while doing any operation on ASM crossing 300+ connection of process.
SQL>show parameter process
NAME TYPE VALUE
processes integer 300
--> I confirmed by checking by ps -aef|grep beq command in linux it shown 380 beq connection.
--> Power limit i given 5 while adding disks to diskgroup..!
--> long back ago we changed ASM Parameter process value to 300 in place of 100.
--> A question like while rebalancing is going node got hanged got alert error like ASM MAXIMUM PROCESS GOT EXCEED so no operation were allowed to the node, so we rebooted the node after rebooted node came in to normal state and able to do all operation normally..but my question is that rebalance is completed succesfully or not?
--> For this issue we need to apply any Patch to overcome this issue in future while doing any operation on ASM
Thanks a lot for your quick reply.
Thanks & Regards

Maximum number of processes (100) exceeded

Hi!
I've some php application working with oracle XE with oci8 driver. Application works fine, but with time number of running oracle processes grows and when it reaches 100, it is impossible to to backup:
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04005: error from target database:
ORA-00020: maximum number of processes (100) exceeded
To do a backup I need to restart oracle.
What is interesting, number of processes doesn't affect php application. I think php can reuse existing processes. It is possible that RMAN will reuse existing processes?
Or is there any way to close unneeded processes ?
best regards
Jarek

With 11g XE, use DRCP connection pooling for your PHP connections. See The Underground PHP and Oracle Manual
Use non-DRCP connections for other jobs.
It sounds like you are using persistent PHP connections. This is good for performance but if you have a large number of PHP/Apache processes you will reach the DB limits, as you've found. You can tune the number of connections to suit the largest possible number of mid-tier processes in your system. Do this with the 'processes' parameter in the DB. See the "Configuring the Database For Testing" section in the testing chapter of The Underground PHP and Oracle Manual. You could also reduce the number of Apache processes that start, or be more aggressive in expiring them.
For follow up PHP questions, use the PHP OTN forum.

ORA-00020: maximum number of processes (500) exceeded

Problem Details:
In our Database we are getting huge number of open connection from remote system.
Let say, our application A and remote application name is B.
Some common users of application A are USER0, USER1, USER2.
Remote Application B uses USER0 to create views on application A's table through Database Link.
Those views (nearly 100) are accessed in application B at several places from the Java code.
Since those views are getting called almost all the times from the application B's code, DB link is in use almost all the time - holding many number of connections (check the first row of the query output).
Many times the open connections remaining high and any other application, users trying to connect to application A,
getting the ORA-00020 error.
Note :
1. Application B is very old application and does not use open DB link or close DB link.
2. Application B tried with "alter session close Database link xxx", it decrease the number of open connection but its degrading the performance of application B at large scale.
3. To cope up with this problem Application A recently incraesed the parameter process=500, but not sure if this limit can also be broken through Application B
Questions/Doubts:
1) What is best approach to handle this problem??
'alter session close database link xxx' is the only option from application B's point ??
What other approach can be taken??
2) We are not sure the risk associated with increasing the process parameter value ??
Appreciate your suggestion !!

ERROR:
ORA-00020: maximum number of processes (500) exceeded
Warning: You are no longer connected to ORACLE.

semmsl in Linux tells what the max number of processes are. You have to make sure this is equal to the process parameter of all instances plus 10.
It is usually in /etc/sysctl.conf
kernel.sem = 250 32000 100 128
SEMMSL
The SEMMSL kernel parameter is used to control the maximum number of semaphores per semaphore set.
Oracle recommends setting SEMMSL to the largest PROCESS instance parameter setting in the init.ora file for all databases hosted on the Linux system plus 10. Also, Oracle recommends setting the SEMMSL to a value of no less than 100.
SEMMNI
The SEMMNI kernel parameter is used to control the maximum number of semaphore sets on the entire Linux system.
Oracle recommends setting the SEMMNI to a value of no less than 100.
SEMMNS
The SEMMNS kernel parameter is used to control the maximum number of semaphores (not semaphore sets) on the entire Linux system.
Oracle recommends setting the SEMMNS to the sum of the PROCESSES instance parameter setting for each database on the system, adding the largest PROCESSES twice, and then finally adding 10 for each Oracle database on the system. To summarize:
SEMMNS = sum of PROCESSES setting for each database on the system
+ ( 2 * [largest PROCESSES setting])
+ (10 * [number of databases on system]
To determine the maximum number of semaphores that can be allocated on a Linux system, use the following calculation. It will be the lesser of:
SEMMNS -or- (SEMMSL * SEMMNI)
SEMOPM
The SEMOPM kernel parameter is used to control the number of semaphore operations that can be performed per semop system call.
The semop system call (function) provides the ability to do operations for multiple semaphores with one semop system call. A semaphore set can have the maximum number of SEMMSL semaphores per semaphore set and is therefore recommended to set SEMOPM equal to SEMMSL.
Oracle recommends setting the SEMOPM to a value of no less than 100.
App B could try using connection pooling or something to reduce the number of connections to the DB.
