Server.xml file getting updated with a character '>' each time we restart instance

Dear Readers,


This is something very peculiar that we have noticed only a few days back.We had a performance issue and had to increase the number of oacore processes to 2 and the maxsize for memory to 1024M.

After we did this each time we restart the instance we had a special character '>' appended to the file server.xml located in /db01/oracle/VIS/inst/apps/VIS_server070/ora/10.1.3/j2ee/oacore/config/ which will prevent the oacore process from starting.

The oacore will exit with the following status

adoacorectl.sh: exiting with status 204

You will recieve the error message as shown below in file oacorestd.err under /db01/oracle/VIS/inst/apps/VIS_server070/logs/ora/10.1.3/opmn/oacore_default_group_1

10/01/27 17:25:52 Error initializing server: /db01/oracle/VIS/inst/apps/VIS_server070/ora/10.1.3/j2ee/oacore/config/server.xml, Fatal error at line 70 offset 1 in file:/db01/oracle/VIS/inst/apps/VIS_server070/ora/10.1.3/j2ee/oacore/config/server.xml: .: XML-20100: (Fatal Error) Expected 'EOF'.


To fix this perform the following

1. Set  server.xml  file access right  to read only mode.
2. Start OC4J  container.

(or)

Apply the patch 6702510 for suitable version of your IAS.
