Hi,
 There is a bug when you asign java_pool_size=0, it happened to me.
 
 ORA-04031: no se han podido asignar 4032 bytes de memoria compartida ("shared pool","unknown object","joxs heap
 init","ioc_allocate_pal")
 Metalink:
 
 fact: Oracle Server - Enterprise Edition 9.0.1 symptom: ORA-00604: error occurred at recursive SQL level 1 symptom: ORA-04031: unable to allocate %n bytes of shared memory (" shared
 pool",%s,%s,%s) symptom: ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 0 symptom: ORA-06512: at line 4 change: Java_pool_size <= 4M cause:
 <Bug:2084844>: ERROR OCCURRED AT RECURSIVE SQL LEVEL 1

 fix:

 Startup the database caused
 following errors logged in the alert file:

 ORA-00604: error occurred
 at recursive SQL level 1ORA-04031: unable to allocate 4032 bytes of shared memory ("shared
 pool",
 "unknown object","joxs heap init","ioc_allocate_pal")ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 0ORA-06512: at line 4

 Afterwards, since the
 database is open, the errors also occur when creating ordropping database objects (tables, external tables, ...), neverthenless withslightly different parameters in the ORA-4031 error message, like:

 ORA-04031: unable to
 allocate 4032 bytes of shared memory ("shared pool",
 "unknown object","joxs heap init","ioc_allocate_pal")

 or

 ORA-04031: unable to
 allocate 4032 bytes of shared memory ("shared pool",
 "sun/misc/URLClassPathSYS","joxlod: in ehe","ioc_allocate_pal")

 or

 ORA-04031: unable to
 allocate 4032 bytes of shared memory ("shared pool"
 "oracle/CDC/ChangeTableSYS","joxlod: in ehe","ioc_allocate_pal")

 The size of the shared
 pool doesn't influence the result. This means thatincreasing the shared_pool_size will not solve the problem.

 The problem is fixed,
 setting the java_pool_size greater then 4M. In fact avalue of 4194305 (4M + 1 byte) would be sufficient, since the java_pool_size isadjusted to a multiple of 4M. In this case the java_pool_size would be 8M.

 It seems that there is a
 threshold of java_pool_size of 5M based on v$sgastat.

 Remark:------

 <Bug:2084844> is
 initially fixed in version 9.2.

  While reducing the JAVA_POOL_SIZE in initfile.... , i observed that minimum   it takes 8M and not less than that.
  If we dont specify this parameter, default value it takes as 20 M   !!.
  If there is no JAVA related stuff in my application / database..., why   should i have this space allocated.?
  Moreover, this space allocation seems to be affecting the PGA size....!!   Any suggestions to make it NULL or zero. ??   Thank you.
  regards, Arul.
