I verified the max 32 applications limit a couple of point releases after 10.4.0. While more than 32 applications can be started, communication will only occur to 32, with any above that limit receiving an error that they could not be contacted. We worked around that by using an adaptor complied for 64 applications.

Now with imminent plans to move to WebObjects 5.4.2 under Mac OS 10.5.4 and a mix of Apache 1.3 and Apache 2.2, I was hoping someone had a quick answer. According to the info provided, the adapter limits for 10.5 are now 64 max applications, and I've made a poor assumption they were still at 32 max instances. Thanks for helping me see.

Does anyone here know what the maximum number of WO apps is when
running with the Apache 2 WebObjects adapter? Environment is Mac OS
X Server 10.5.4 with WebObjects 5.4.1 or 5.4.2.

Under Mac OS X Server 10.3 - 10.5, the out of box config for Apache
1.3 is 32 running applications (not instances but applications), but
have to include the java monitor.


        Are you sure about the 32 application maximum with Apache 1.3?
Source for both the Apache 1.3 and 2.2 adaptors is included in /
Developer/Examples/WebObjects/Source/Adaptors on all WO developer
systems.  It appears that both adaptors share the same config.h file
which contains

#define WA_MAX_APP_COUNT                64      /* maximum number of 
applications the
adaptor can keep track of */
#define WA_MAX_APP_INSTANCE_COUNT       128     /* maximum number of instances
of a single application the adaptor can keep track of */

        I just checked the Apache 1.3 source included with WO 5.3/OS X 10.4.
config.h includes the same defines as the version included with WO 5.4/
OS X 10.5.  So I don't think that these limits have changed.

Aloha,
Art
