Rolling upgrades are here Finally available, with the 12.10xC5 release, the Informix Server now permits to us to do an upgrade for a high-availability cluster to the next fix pack or interim update (PID) with minimal interruption to client applications. During the rolling upgrade process, the cluster remains online even though the servers in the cluster are running on different levels of the software. For example, to upgrade from 12.10.xC4 to 12.10.xC5: Stop a secondary server in the cluster, install the new fix pack on it, and then start the upgraded server. After you upgrade all of the secondary servers, stop the primary server and promote one of the secondary servers to the primary server. Then, you can upgrade the original primary server, start it as a secondary server, and then promote it back to primary server. The rolling upgrade process, as well as prerequisites and restrictions, are documented in the IBM Informix Migration Guide. Additional information is available in the What's New in Informix page.

IIUG New Features Survey We've gathered the best of the IBM Informix Requests for Enhancement from the past year: http://goo.gl/forms/awkAdQjNmM Please indicate which features would be useful to you and your organization. The survey results will be tallied, summarized, and passed on to the IBM Informix Development Team.
Just in case you are not aware, some time ago IBM created a public website to collect the requests for new features directly from users. The RFE (Requests For Enhancements) website is included in developerWorks. You can access it here. Once you logged in with your usual IBM ID, choose "Information Management" in the Brand dropdown box and "Informix Servers" or "Client Products" in the Products dropdown box. The interesting thing is that any request, including your request, if you place one, are submitted to be voted on. This means the RFEs that receive more votes have a greater chance to be considered by the architecture and development teams for further consideration. In other words, this IS the opportunity to provide enhancement ideas even if you are not the biggest IBM customer on the planet Earth. Some RFEs will be of great interest, others will not seem useful to you. This is why your opinion is important. Do not hesitate to vote and place comments! The idea of the RFE corner is to provide a digest on new Informix RFEs and make those RFEs more visible and accessible for the community, so that you can vote for them in a faster and easier way. By participating actively in this website, IBM will have solid and useful elements from the customer base to introduce new functionality to Informix product. Also in the area of IBM website, a new functionality has been released: MyNotifications. You will want to register this webpage in order to receive the notifications of your choice (new product defects, new patch release, new versions etc..., on the frequency of your choice (daily, weekly). I have registered and will definitely keep registered, due to the value of the information delivered. New RFEs for March 2015 UTC/GMT timestamp conversion function for Informix database Informix does not have a UTC/GMT timestamp conversion function. Requirement:
Working system-calls from sysadmin tasks with Informix for Windows Automatic Backup Tasks started from within the sysadmin-scheduler don't work on windows systems. The same problem with every other system-call. This is a Windows-specific problem. On Linux systems this works as intended. When executing a DDL statement one can expect the following error message: 106: ISAM error: non-exclusive access Using the SET LOCK MODE command and placing a exclusive lock on the table will not prevent these behavior. These error can occur if there are sessions querying the table wit isolation level set to 'dirty read'. You can prevent these last one by setting the environment variable IFX_DIRTY_WAIT, that define the number of seconds a DDL statement will wait for existing dirty readers to finish and prevents new dirty readers from accessing the table. But these don't prevent someone to try to place a lock using the SET LOCK MODE command and again preventing the table to be altered. There can be no sessions with open structures on the table. So we can identify the sessions that have the partition open, we start by getting the partnum of the table in hexadecimal querying the sysmaster:systabname, these action must be done before the DDL statement. It is also important to get our sessionid before we start to kill the sessions, we can get it by calling DBINFO('sessionid'). Then after the DDL statement get stucked we can check the In-memory address of the RSAM thread control block (rstcb) for the threads that opened the partition, with something like:
onstat -g opn | grep -i Then, to get the sessions we have to grep the onstat -u command with the result above. Clean it to get only unique ids and descarding our session and then killing the sessions through onmode -z command. Now, in a "wild" production environment it's a long road to follow. Here are some features that can be added:
Add a function to output the cause of information the Remote TMU error 12033 The customer encountered Red Brick Remote TMU Error 12033 occurred. Red Brick Remote TMU Error 12033 message is below. They can't found cause of the error. ** FATAL ** (12033) TMU Driver could not connect back to TMU Client. The Error 12033 cause of network problem or Remote TMU client was too busy and could not open the port in time. In this case, please add a function to output the cause of information the Remote TMU Error 12033. The customer necessary to explain an investigation into Error 12033 occur. Query on table of 64MB uses over 93 GB of tempspace and fails Query that is generated by Cognos on a fact table of less then 100.000 rows, 16374 pages of 4KB is running out of temp space. There are 3 tempspaces of 8.192.000 pages of 4KB, in total 93,75 GB of temp space. Query is not optimally generated by Cognos and contains 80+ count(distinct xxx) clauses. But even then it is not exaplanable that this query does not have enough temp space. Today we are able to prepare RPM that can be bundle and redistributed as per our requirement. When I do an information rpm query on each individual package I see that the summary and description doesn't give correct information. Here is a sample rpm command output for each RPM: rpm -qip server/RPMS/x86_64/CSCOinformix-server-12.10.FC4W1XK-1.x86_64.rpm rpm -qip client/RPMS/x86_64/CSCOinformix-client-12.10.UC4W1X1-1.x86_64.rpm I would like suggest an enhancement change/bug fix for being able to correct this based on a parameter value defined in bundle.properties file If the description and summary can be customized by defining a variable and value in bundle.properties that is used by ids_install script to create the RPM then we would have better RPM information when a query is run for information against an RPM. E.g. of bundle.properties that I am using: [root@cscolxplat8 anavale]# cat csco-server.bundle.properties Variable and value that I mentioned above would be populated in the bundle.properties like we are currently doing for RPM_PACKAGE_BASE_NAME , RPM_PACKAGE_VERSION, RPM_PACKAGE_RELEASE. ENABLE ONCHECK DATA CROSS-CHECKING FOR FUNCTIONAL INDEX oncheck -cI on a functional index still says: "Non vanilla index. data crosschecking not enabled" After so many years supporting functional indices we should consider enabling this. I had a customer with a corruption in a functional index on a huge table that only surfaced when he eventually tried to delete the affected row. He'd like to check this index now more frequently to find other such corruptions and/or to better determine the point in time when such corruption gets introduced. Enable "Shrink" for indices alone, aside from the "Shrink" for tables 32 and 64-bit Redbrick ODBC drivers certified for IPV6 Protocol System: Product NITRO Actor: Users are migrating their VPNs from IPV4 to IPV6 due to which there is a need to certify NITRO for IPV6 protocol. Description: Nielsen NITRO is desktop application that has capability to connect to red brick databases via drivers using odbc connectivity. As per our testing with Direct Access VPN that supports IPV6 protocol the connectivity to redbrick databases failed while using Redbrick ODBC drivers mentioned below, Up on further analysis of network traces it was understood that the problem is due to the fact that Redbrick drivers being used are not complaint with IPV6 protocol. Redbrick ODBC driver Certified for Windows 10 Currently we are using following Redbrick driver version in our application, We know that the ODBC driver versions mentioned above works on Windows 7, Windows 8 and Windows 8.1. But we would like to know a version that is certified for Windows 10 (both 32 and 64-bit Redbrick driver). Remove the physical storage limitations on Innovator-C At release of Informix Innovator-C Edition 11.70 xc5, a large number of functionality has been withdrawn ( ER and more), as well as new ressource limitations have been implemented or inreased, such as limitation to 1 CPU vp for instance. We think that many of those limitations are justified and acceptable for a free of charge product. Nonetheless, we strongly think that the the 8Gb storage limitation is a show stopper and should be removed. We request the withdrawal of the storage limitation of 8 Gb for Innovator-C.
