IFS ALERT NOTICE FOR JDBC MEMORY LEAK FIX

Product and Version Affected:

Product: Oracle Internet File System
Product ID: 7
Version: 1.0

Description: There is a memory leak when retrieving or saving BLOBs through JDBC. IFS will appear to continue to increase in its memory consumption until the user runs out of swap space, and the machine stops functioning.

Platform Affected: Sun SPARC Solaris, Windows NT

Likelihood of Occurrence: Most iFS customers will notice this problem, since most will retrieve and store enough document content that they will notice the memory leak.

Symptoms:
- Performance becomes unacceptable on a minimally configured machine when doing significant retrievals and storage of documents.
- Significant swapping of the operating system.
- The user sees real memory and total memory continue to increase without bound when using any iFS protocols to retrieve and store document content.
- The memory usage goes back to normal when the iFS protocols are stopped.

Solution: Get the JDBC 8.1.6.0.1 patch for Solaris or NT (the OCI component, for JDK 1.1). Install it on all machines where the iFS protocols are running. The patch may be obtained on http://technet.oracle.com/software/tech/java/sqlj_jdbc/software_index.htm (you have to be logged into technet).

Be sure to get the OCI component of JDBC 8.1.6.0.1 for JDK 1.1.
