Oracle Sql Developer Java Heap Space Error

Comments If you work with large SQL files in Oracle SQL Developer you will get out of memory errors from the Java sql developer increase memory VM it runs within. To fix this problem, you need to increase

the Xmx (maximum heap size) from the default 128MB. If you start SQL Developer by creating a sql developer java heap space protocol violation desktop shortcut to SQL Developer.exe, you cannot pass the -Xms parameter and instead need to edit the sqldevelopersqldeveloperbinsqldeveloper.conf file, adding the following line:-
AddVMOption -Xmx1024M The file is notSql Developer +"cannot Be Opened Due To The Following Error: Null"
formatted with the correct line endings (I guess from Linux/Java build) so you will need to open it with a smart text editor like Visual Studio 2005 or later, which then correctly detects and terminates the lines, otherwise it appears as one big line in Notepad.

It was very helpful. Reply Innocent JB says: 17 March 2012 at 15:10 Thanx a million ! Reply Anchee25 says: 23 October 2012 at 04:42 Hello, The error messages ‘Java heap space' and ‘Protocol violation' no longer appear after I added the suggested line into the config file. Thank you so much for this useful and helpful tip. Reply Alex Lu says: 13 March 2013 at 12:18 Hi I need to use the developer tool to open a 271MB sql file. I added AddVMOption -Xmx1024M I still get the same error msg when I tried to open the file. Reply Code Chief says: 24 March 2013 at 16:56 Sorry I can't help with that. The extended memory settings will help with relatively large (20MB+) files but at some point there will always be a limit (try opening 40MB or more in Windo

When http://blog.tonywall.co/2008/07/configuring-oracle-sql-developer-for-large-files-fix-out-of-memory-errors/ I connect to a particular db and run a simple select * from table1; I get the result set. (Still happens regardless of the number of records in the table, which is few, however the table does contain over 170 fields) If I try and run it a second time I get a java heap space error. If I try and run it again it starts throwing Protocol violation errors, with a different numbered protocol error http://stackoverflow.com/questions/36311344/oracle-sql-developer-heap-space-error-potocol-error each successive run. I have never experienced this problem with other oracle db’s, even when connecting through the same installation of SQL Developer. The only way for me to be able to query that table again is to reconnect to the db. Other users of this same db do not experience this problem. Has anyone ever experienced this issue? java oracle11g oracle-sqldeveloper share|improve this question edited Mar 30 at 18:39 asked Mar 30 at 14:08 Michael B 1045 4 Consider not using UPPERCASE ONLY for your titles; as UPPERCASE translates to SCREAMING for many folks using the interwebs. –GhostCat Mar 30 at 14:11 1 Does the problem go away if you increase the JVM memory allocation? –Alex Poole Mar 30 at 14:18 Yes that fixed it.

more memory. Here's an example: you want to model a database that has 1500 tables in it. What would that even look like? If you zoom out far enough… 3800 views in one model - not very pretty Now, ‘large' is a subjective term. But lets put it http://www.thatjeffsmith.com/archive/2014/06/configuring-memory-usage-in-oracle-sql-developer/ this way - if you're dealing with more than several hundred tables or entities - that's larger than most other designs. Oracle SQL Developer Data Modeler, and the modeling extension that runs inside of Oracle SQL Developer, consume a lot http://blog.takechances.net/2011/12/increase-memory-size-for-sqldeveloper.html of resources to render the diagrams. Also, each model artifact is stored in its own XML file. That's all loaded into memory when you open a design. So, if you're gonna work with a ‘large' design, you're going to need sql developer more memory than you get ‘out of the box.' SQL Developer is a Java Swing application. It requires the JDK. There are several Java Virutal Machine (JVM) directives that tell it how to behave. You can see how SQL Developer has configured its JVM settings and monitor its memory usage using a cool program called ‘Java VisualVM.' It's in your JDK/bin directory as jvisualvm.exe. If you open it and attach to the sql developer process ID, you get to see a sql developer java lot of cool stuff. How is Java configured to run? Like, how much memory SQL Developer is ACTUALLY using - by the way, Windows Process Explorer will lie every time. SQL Developer is using way less memory than Windows thinks it is. In older versions of SQL Developer, these were stored in the sqldeveloper.conf file in the bin directory - for Windows. In versions 4.0 and higher, this is now stored per user in Windows. For the Data Modeler, you want to find this file C:\Users\jdsmith\AppData\Roaming\Oracle SQL Developer Data Modeler\4.0.2.840\product.conf The italicized bits will vary per machine and version you're running - but this should get you close. You want to open the file with the application closed. Edit the last bit [text] If you are getting the ‘Low Memory Warning' Message Dialog while running # the product, please increase the -Xmx value below from the default 800M to # something greater, like 1024M or 1250M. If after increasing the value, # the product is no longer starting up because it fails to create a virtual # machine, then please reduce the modified -Xmx value, or use a 64bit JDK # which allows for very very large value for -Xmx. # # You can specify one value for any JDK using AddVMOption, OR you can specify # separate values for 32-bit and 64-bit JDK's. # AddVMOption -Xmx800m # Add32VMOption -Xmx800m # Add64VMOption -Xmx800m [/text] In particular the last
can't even pass in the options on the command line. I'm not sure about Mac or Windows, but on Linux, it's pretty easy, just edit your ide/bin/ide.conf file and change the lines "AddVMOption -Xmx640M" and "AddVMOption -Xms128M" lines to something larger (or smaller). You can see what I have mine set to below.
