SHMBASE

Informix 11.70 AIX 780 The following error appears in the logs. While this is a warning message, we would like to get rid of it. WARNING : If you intend to use J/Foundation or GLS for Unicode feature (GLU) with this Server instance, please make sure that your SHMBASE value specifies in onconfig is 0x700000010000000 or above. Otherwise you will have problems while attaching or dynamically adding virtual shared memory segments. Please refer to Server machine notes for more information. After doing some research in the machine notes it states that ...When using IBM Informix Dynamic Server with J/Foundation, the ONCONFIG variable SHMBASE should be set to the following: SHMBASE 0x700000010000000... There are numerous document stating not to change the SHMBASE. However, on one of our test systems I changed the SHMBASE to 0x700000010000000. Restarted the server and the message no longer appears. Please confirm that this change will not affect anything else. Thank you, Christine Bizukiewicz Shubert Ticketing

Christine, this should be safe. The only problem you are likely to run into would be if SHMBASE interfered with the attach address of some shared library. That, however, would prevent the engine from starting, so you will know immediately. Art Art S.
