SHARED MEMORY NOT INITIALIZED

I've installed my 7.3 online dynamic server, followed the instructions in the admin manual regarding configuring sqlhosts and onconfig, BUT I cannot init my dbserver. message is "shared memory not initialized for INFORMIXSERVER ..." I am running linux redhat 2.0.36. According to the release documents that came along with the informix software, I need to install a bunch of kernel patches so I can have 3000 max file descriptors, rather than just 256. I have yet to do this because redhat's ftp site is slow as molasses. Is this the reason why I am having difficulty initiating my database server ? Here is the entry in my sqlhosts file, my dbserver name is batangas. I want to be able to access it via 2 protocols, local shared memory and networked sockets. hostname is peord. I created an alias in the onconfig file named "batangas_tcp" and set corresponding NETTYP field for it. batangas_tcp onsoctcp peord batangas_tcp batangas onipcshm peord batangas_shm attached is my onconfig file. any help would be appreciated thanks dja7@jps.net

You might need the patch for NET connections that is on INFORMIX's web site for LINUX. To see if you do, set up your ONCONFIG to use just shared memory connections and see if it comes online. If so, you need the patch listed on that Linux Web Page --- the same page where the product can be downloaded. Take care. =============================================== Clifton M.

There is a bug on Linux, when poll thread can't run in-line. Also, check if SHMBASE is set properly. If all of above wouldn't help, send us your message log and 'oninit -v' output. Information, you gave, is too low to help you. -- With best regards, Yuri Dovgart, SAP R/3, Informix consultant, "Telecominvest" company.
