Ora-4030
Have you observed anORA-04031 error reported in your alert log? An ORA-4031 error is raised when dde: problem key 'ora 4031' was completely flood controlled (0x6) memory is unavailable for use or reuse in the System Global Area (SGA). The error message will indicate the memory pool getting errors and high level information
Ora 04031 Unable To Allocate 4096 Bytes Of Shared Memory
about what kind of allocation failed and how much memory was unavailable. The challenge with ORA-4031 analysis is that the error and associated trace is for a "victim" of the problem. The failing code ran into the memory limitation, but in almost all cases it was not part of the root problem. Looking for the v$shared_pool_reserved best way to diagnose? When an ORA-4031 error occurs, a trace file is raised and noted in the alert log if the process experiencing the error is a background process. User processes may experience errors without reports in the alert log or traces generated. The V$SHARED_POOL_RESERVED view will show reports of misses for memory over the life of the database. Diagnostics scripts are available in Note 430473.1 to help in analysis of the problem. There is also a training video on using and interpreting the script data Note 1087773.1. 11g Diagnosibility Starting with Oracle Database 11g Release 1, the Diagnosability infrastructure was introduced which places traces and core files into a location controlled by the DIAGNOSTIC_DEST initialization parameter when an incident, such as an ORA-4031 occurs. For earlier versions, the trace file will be written to either USER_DUMP_DEST (if the error was caught in a user process) or BACKGROUND_DUMP_DEST (if the error was caught in a background process like PMON or SMON

I don't know if this is a simple server setup problem or an application design problem (or both). Once or twice every few months this Oracle http://stackoverflow.com/questions/994182/resolving-ora-4031-unable-to-allocate-x-bytes-of-shared-memory XE database reports ORA-4031 errors. It doesn't point to any particular part of the sga consistently. A recent example is: ORA-04031: unable to allocate 8208 bytes of shared memory ("large pool","unknown object","sort subheap","sort key") When this error comes up, if the user keeps refreshing, clicking on different links, they'll generally get more of these kinds of errors at different times, then soon they'll get "404 not found" page errors. Restarting the database usually resolves the problem for a while, then a month or so later it comes up again, but rarely at the same location in the program (i.e. it doesn't seem linked to any particular portion of code) (the above example error was raised from an Apex page which was sorting 5000+ rows from a table). I've tried increasing sga_max_size from 140M to 256M and hope this will help things. Of course, I won't know if this has helped since I had to restart the database to change the setting :) I'm running Oracle XE 10.2.0.1.0 on a Oracle Enterprise Linux 5 box with 512MB of RAM. T
(troubleshooting) Problem(Abstract) When exporting data from Maximo to an External System by using Interface Tables, Maximo may raise an error as http://www-01.ibm.com/support/docview.wss?uid=swg21515454 above. Symptom OutBound Interface cannot send data out. You will see an error similar to the following: nullBMXAA4210E - Database error number 904 has occurred. ORA-00904: "PLUSCISMTECLASS": invalid identifier Cause This error happens due to a column mismatch between the Maximo MBO and the Interface table. When a new Product, Industry Solution or Add-on is installed, new columns may be added unable to to Maximo core tables, but these columns will not be automatically applied to the Interface Tables and when MIF tries to write data in to the iface tables the insert will fail and raise the error ORA-00904 Environment Maximo 7.x Database Server: Oracle Resolving the problem There are two possible solutions for this issue: 1 - Re-create the Interface Table in the unable to allocate External System Application. All data in the Interface Table will be lost. 1.1 - Go to > Integration > External System > 1.2 - Select any External System 1.3 - Select Action > Create Interface Table > 1.4 - Select the endpoint and the table to be recreated > Click the Create Button 2 - Remove the "Invalid" column from the Object Structure Schema. 2.1 - Go to > Integration > Object Structure 2.2 - Select the Object Structure being used 2.3 - Select Action > Exclude / Include Fields 2.4 - Check the "Exclude" checkbox for all fields you want to remove. 2.5 - Click OK 2.6 - Select Action > Generate Schema / View XML > OK 2.7 - Click OK in the Pop-up dialog Retest your Integration.
